This is a port of Cyanogenmod 13 for the Samsung Galaxy Tab A 7.0 (2016) LTE SM-T285. Cyanogenmod needs no introduction, it is one of the most popular aftermarket ROM distributions around.
5.1.1 is the best that you can get from samsung right now and it is not known if they plan to do any upgrades. I have absolutely no idea why samsung chose to stay with the outdated 5.1.1 mid 2016 when we already got 7.1 coming out. This custom rom is probably the best you can get if you want an upgrade from Lollipop. Performance on the latest build is also better, you be the judge.
This ROM is stable enough to be my current daily driver, however please take note of the issues noted below. Feature are on par or exceeds my OMNIRom builds in terms of features and performance. However do note that CyanogenMod has a lot more features and brings about its own bugs as well.
Based off on Cyanogenmod 13 sources which is based on Marshmallow 6.0.1

Update Jan 28, 2017
===============
New XTRM build released. Overview of changes:
* kernel and framework built with -O3 compiler flag for deeper linaro optimizations
* Video recording now works
* Added I/O scheduler support to the kernel
* reduced OC to 1.54 from 1.56 (actually faster at this clock)
Update Jan 16, 2017
===============
CM 13 Xtreme builds now available! See section below for details.
Update Jan 07, 2017
===============
A build with SELinux enforcing and support for F2FS in the data partition is now available. If SELinux security is important for you and if you want the Filesystem performance benefits that F2FS brings, I invite you to check it out the section below. Note however that a Data Wipe is necessary.
Update Dec 14, 2016
===============
- Fixed hardware acceleration for some videos (lower power consumption in YouTube etc.)
- Fixed crash when a call has ended
- ScreenRecorder/ScreenCasting now works.
- Added reboot menu options (Needs developer mode)
Works:
- Wifi/SMS
- Audio
- Graphics
- GPS
- Wifi Hotspot
- Incoming/Outgoing Calls
- MTP
- Bluetooth
- Camera (stills) - but video works in xtrm-20170128
- LTE
Bugs/Known Issues
*Unable to record video using camera* (Fixed in xtrm-20170128 build)
*FM Radio crashes*
*gps unable to get a fix*
*poor sound volume (can possibly be fixed by sound mod add-ons)
*speakerphone issues during call*
Other Notes:
- selinux permissive (There is a special build with selinux enforcing in the section below)
@Vagr9K has a fix for gps issues here: https://forum.xda-developers.com/showpost.php?p=71999226&postcount=42 thanks1
Most of the issues are fixable, I just need more time and encouragement
SM-T280 Users: Unfortunately this rom would probably not work on it since the SM-T285 and SM-T280 have different kernels and slightly different hardware. I don't have access to this device so it would be hard for me to port it over. However I believe there are a lot of similiarities in the device tree that can be shared. If a dev with the SM-T280 is interested I can probably help.
Download
========
Remember flashing an unofficial ROM on your samsung device will probably void your warranty, Samsung representatives will probably not be able to help you as they are still stuck at 5.1.1 land as of now and have no idea how to handle a SM-T285 that is running 6.0.1.
As always flash this at your own risk. Make sure you have a copy of the stock ROM so that you have something to fall back to, which is highly the case when using an experimental rom.
See DevDB download section. Or click here for the latest version.
Note that this rom is pure stock and does not come with the Play Store or any Gapps, I suggest you download a micro gapps package separately and install it via recovery.
There have been reports that recent versions of open gapps don't work properly, it is advised to use older versions instead (e.g. open_gapps-arm-6.0-nano-20161109.zip)
Finally if you enjoyed this ROM and like what I'm doing, hit the thanks button or better yet hit the donate button.
Installation Instructions
==================
Perform a backup of all of your important files. This ROM is experimental and I will not be responsible for your loss of data.
Download the zip file and extract the tar.
Use Odin/Heimdall to flash the tar file to your device. If you are coming from stock oranother rom make sure you wipe first using TWRP. Coming from a previous version of OMNIRom for SM-T285 may not require a wipe, however please perform a wipe if you encounter problems.
Using the F2FS and selinux enabled version (WIPE Required)
-------------------------------------------------------------------------
Recommended to move over to the Xtreme build instead (01/17/2016)
1. Flash the custom F2FS version of TWRP for the SM-T285 here using Odin/Heimdall. If coming from another ROM or even a non F2FS version of CM you need to format your data partition to F2FS using this twrp so make sure you take the necessary backups.
2. Download an flash using Odin/Heimall CM 13.1 F2FS Edition here.
Other Notes: Antutu Scores for reference (6.0.1, F2FS) : Overall: 25830, 3D: 914, UX: 10397, CPU: 10606, RAM: 3913
Xtreme Edition Builds
=================
Xtreme Edition builds are aggressively optimized and possibly unstable builds (though I do test them for some time to ensure minimum stability). Warning this build is only for enthusiasts that want to tinker settings to achieve the best performance possible for this device (using Kernel Auditor is recommended). Speed should be noticeable especially when coming from stock or non optimized builds.
Feature List:
* Kernel and system files compiled with the latest linaro toolchain 6.2.1 with -O3 optimization
* Additional hotplug and CPU governors installed (tweak with your hearts content with Kernel Auditor)
* Max clockspeed slightly bumped to 1.54Ghz from 1.5Ghz
* Various speed optimization patches to the kernel
* Support for KSM (Kernel same page merging)
* Support for both Ext4 and F2FS for the data and cache partitions (Use TWRP to switch to your desired FS)
* SELinux enabled
* ExFAT and NTFS support built-in
* Improved doze and low power mode support
* Antutu Score 26325 (KSM disabled, IntelliPlug Enabled, F2FS data and cache partitions)
* USB Audio/MIDI support (untested)
* Added new I/O schedulers (row, bfq etc.)
* Other optimizations and fixes I can't remember
For GPL compliance please look at the github source above, kernel sources for Xtreme builds are under the performance branch.
Issues
-------
Known issues are the same with the standard build (e.g. video recording not working etc.) However due to aggressive kernel changes this build may not be as stable as the standard build.
Download & Installation
-------------
This build supports both Ext4 and F2FS filesystems so a wipe isn't strictly necessary unless you want to switch filesystems using TWRP. However I won't be responsible for data loss, so make sure you make the necessary backups.
Grab the latest build here
If you haven't updated TWRP, get the latest build with F2FS support and the latest kernel here.
Root and customization
===================
Cyanogenmod already comes with its own root mechanism, you have to enable it in developer settings though.
If you want to customize this ROM and repackage it you may use this guide as a reference.

speakerphone still does not work but not a big deal at the moment
theme manager too! and it works!
checked data, calls in and out , sms, mms, wifi (of course you had already said it works..just 'reporting')
thanks!

one thing-theme manager crashing (clearing its cache and data did not help) but this started only after installing one theme and then switching over-wish there was a simpler list view vertical rather than the horizontal intensive scroll view-anyway it crashes and keeps resetting the view to the first default theme when I go in (try to scroll sideways and it will not as it crashes and comes back to the first system default theme)-resetting to default system theme did not stop the crash reports..popups of it stopping keep coming and am not able to do anything with the theme chooser....not sure I downloaded too many themes or what-will remove some themes to see if it changes anything
lte/h+ icon in status bar varies in its presentation-will sometimes show up sometimes won't even when on mobile data (and the data works)...thought at one point I saw both that and the wifi icon showing (wifi was on then) (changing clock position did not help)
When adding a contact, and choosing a photo the screen changed automatically to automatic live display mode (when I had it turned off)..the color shading changed completely of everything indicating a filter of sorts (which is what the live display does I think among other things)
not sure if these are consistent but will try again (maybe even resetting and starting all over-unless you know of any of these or have any insight into them) thanks!
also like omni...process phone stops sometimes on ending a call not a big deal but just reporting

system.img is a sparse ext4 image. You need to use simg2img and mount it as an ext4 filesystem. What device do you want to port it too? This works only for the SM-T285 right now.

I see. Though you probably need to be able to build a new kernel and boot image for this to work though, I doubt just flashing the system image would just work.
Though I'm surprised this spreadtrum phone is still at android 5.1 this december 2016 when clearly we can go up to 6.0.1 with minimal problems

Not sure if it is a cyanogenmod bug or mine. I've updated again with the latest nightly maybe it will be fixed.

That crash, should now be fixed in the latest build.
ROM is actually usable for me now as a daily driver and have since switched from OMNIRom.

awesome! thanks..downloading now (the theme chooser crash occurs now and then when switching between themes but no big deal-there are some themes that have issues but that is a different matter nothing related to this excellent rom...it seems switching back to the base theme creates issues but not trying this anymore for fear of getting stuck-backups always are useful)

One thing though about the CM ROM (versus the OMNI)
If on call, the person at the other end will hear his echo
I tested this myself, knowing this issue from CM/AOSP/Resurrection etc from Tabpro 8.4 etc devices (all of this tablet phone types where the speaker/microphone arrangement placement I believe is different from regular smartphones)
on Tabpro and this was on 4.4 and 5.0.2, I had to adjust some values in an audio mixer file (not just the gains as lowering gain would reduce in-call volume too but actually turned one microphone off to use another) (top microphone versus the lower one but turn on gain so person at other end could hear..something like that if I recall correctly from early 2015..nothing was perfect though)
Here on Omni and CM I reported the speakerphone as not working. However, and this is more evident in the CM rom, the caller's voice at the other end is unusually loud and moreso does not sound like coming from the internal in-call speaker but from the external speaker, albeit at a very low volume. (like the Xperia Z3 Tablet compact that does not have a separate speaker for the call and uses the regular media speaker at a very low volume, though folks have said it is loud enough that other people can hear what is being said by the caller (to your phone). This sounds like that on the CM ROM...and therefore this is picked up by the microphone that then is heard as an echo for the caller (hearing his/her own voice). In the OMNI, this is not there i.e. I do not hear echo on my 'caller' phone (once I move suffiicient distance away from the device with my 'caller' phone)..on the CM it does not go away...when people are speaking rapidly they will not hear the echo usually but if they pause and say things slowly or say single words they could hear echo of their voice.
I am restoring the OMNI backup I had to check it again and copy out the system/etc/audio files to see if there is any difference with the CM
I think something can be changed in the audio files to make use of the speaker and microphones correctly (may also fix speakerphone issue)
This is a perennial issue on almost all CM/non-stock ROMs for Samsung tablet phones (think even the tab S had this issue with CM and so did the T235)...even OneplusOne (which used CM on some of its models) though there I am surprised the users had this issue
..although like on Note 1, Note 2 I never had this issue...suspect it is because of tablet phone differences in the speaker and microphone layout
maybe I am not wording or describing this properly or just that I could be wrong but thought I'd post this
EDIT: Yes tried the OMNI again and it works just fine..no echo
EDIT2: I swapped the OMNI etc folder audio files for the CM and now the echo has gone (so just like Omni...had 2 long calls today-one caller I know is very audio-sensitive and picks up the echo quickly-no complaints!) still trying to understand why this 'worked'

Glad to see that someone is actually using this device for making calls, I use the SM-T285 as a secondary device so i don't use it for calls as much. I appreciate that you are taking the time to test this things. Interesting find on those etc files, I'll try to perform a diff to find out, unfortunately CM makes much more tweaks to stock android than OmniRom does and it makes it hard to figure out where the bugs are coming from.

well...something else..on CM only not OMNI there is a quirk...say I put the phone on call forwarding it will show a call forwarding icon in the status bar which is what is expected...however on reboot that icon may disappear...I missed couple of calls having put the device on call forwarding to my work phone (as it gets a certain carrier coverage Verizon in some work areas where my personal provider ATT does not have)...then forgot about it, put it on mute, and was using the Tab not knowing it was on call forwarding (as sometime during the day I had rebooted and the icon had disappeared)
Further, this also happens like say I am on call forwarding on omni or stock and then went to twrp and restored a cm backup...when the phone comes back on restored with the cm backup the call forwarding icon may have disappeared (does not happen say with call forwarding established on cm, then restored omni backup..the icon remains in omni)
what is disconcerting is if I go into call forwarding it shows that I am not on it (although I am) and actually allows me to turn on call forwarding! (and then turn it off i.e actually disable it if I want to)
also it seems another 3 times I have missed calls on CM...seems the signal drops off more on CM (maybe a rendering thing on signal bars but in checking the signal db and band it does seem weaker)
so for now going back to Omni..although I miss the theme manager and the font changing with your own fonts (not like inbuilt in some font app like fontser) (manual replace of Roboto-regular.tff in system/fonts works to change the font in Omni)

CyanogenMod is a free, community built, aftermarket firmware distribution of Android 4.4 (KK), which is designed to increase performance and reliability over stock Android for your device.
------------THIS IS AN UNOFFICIAL UNSUPPORTED BUILD-----------
This is my attempt at porting CyanogenMod 11 to the Galaxy Tab 4 10.1. I use a SM-T530NU, so that is the only device I have tested.
Any other device variations have not been tested and are at your own risk. I will not be able to support other variations as I don't own them for testing.
Special thanks to MetaIIica - I have been using his Alpha build of PAC-ROM KitKat since December. I studied the code for that, along with stock and some other ROMs before starting this port. This is my first time doing any work with Android, so I'm not sure if I'm technically doing things correctly or not.
I know CyanogenMod 12 is under development already, but I have decided to do a CM11 based build in hopes of a making a stable daily driver offering. I have fixed many of the issues present that were present in the PAC-ROM build. They can probably be backported to PAC-ROM easily if its built with my tree, but I prefer the plain CM-based offering myself.
You may get the source of my changes for this ROM on my github. If you'd like to help and submit a patch, feel free to open a pull request. You will of course be credited accordingly.
See below for instructions, what's working, and issues I fixed over the PAC-ROM Alpha.
For any bug reports or feature requests, please use the appropriate tabs at the top of the thread. Please include as much information as possible and if possible a logcat or other debug information in the case of bugs. Requests for supporting other device variations will not be honored - sorry,
Feedback and constructive criticism is always appreciated. I hope you enjoy using the ROM; if you use the ROM, please consider leaving a thanks, rating, and/or review

INSTRUCTIONS
- Install PhilZ Touch Recovery (recommended)
- Copy CM11 & GAPPS (Optional) ZIPs to your SDCard
- Boot into Recovery
- Do "Clean to Install a New ROM" (FULL WIPE REQUIRED INCLUDING SYSTEM, NOT JUST DATA/CACHE - even if coming from another CM-based ROM, as my device tree is different)
- Flash CM11 ZIP
- Flash GApps zip from SDCard
- Reboot
UPGRADING
-In general, you should be able to just flash over the previous build, but if you encounter any weird issues please clean using the steps above
Working that I've tested:
Audio: Speakers, Headphones, Bluetooth
Bluetooth
CIFS/NFS (Network File Systems - see notes below)
Front Camera
GPS
IR Blaster [SM-T530NU Only]
Magnetic Cover Sleep/Wake
MTP
Rear Camera
USB OTG
Video (w/ Hardware Decoding)
WiFi (2.4ghz & 5ghz)
NOTE ON BUTTONS: This ROM is configured to use the hardware buttons-- so you won't see the software buttons taking up space at the bottom of the screen, as they are disabled. This is not a bug. Use the hardware buttons, as they are the same. If you really want the software buttons for some reason, edit /system/build.prop, change qemu.hw.mainkeys to 0, save, and reboot. If you map the menu button to a long press of another button, some apps such as TitaniumBackup will count this as a hardware key and hide their soft menu button - but only after a reboot.
NOTE ON CIFS/NFS: Many of the mounting utilities on the play store are outdated and broken due to changes in the linux kernel. For best luck, mount using the command line. For CIFS, you can tweak CIFSManager into working - see this thread

Congratulations ! :good:
Nice ROM, it installed fine on my T530 will test some more, thanks for the hard work
I got this installed but the back button and recents button didn't work at all. Its a fast rom though but it would be nice if it was a barebones CyanogenMod without the Pac Rom extras installed too.
Time for a new test, i'll test it in my t530 and report back the results.

It is a pure Cyanogenmod without the Pac extras. If you're seeing them, make sure you did a full wipe before flashing as noted in the original post - you may have remnants of PAC-ROM in /system. The best way is to use PhilZ option to "Clean to Install a new ROM" as that wipes everything correctly. That could also be causing your issues with the back button as well. I completely rebuilt the device tree for this rom over the pac build, as that was based on MSM8974 when this is an MSM8226 device. If a full wipe wasn't done, you have stuff for the other device tree in /system that will mess things up. If the issue persists after a full wipe, please let me know what varient of 530 you're using, and pastebin a logcat of what happens when you press the back or recent events buttons.

I always completely wipe everything before installing a new rom. Never wiping the tablet before installing a new rom might cause problems. I no longer have the rom installed. I will install it again and see if it was just a flike that it didnt work properly the last time. I also have Philz recovery installed because its the only one that has full brightness on the screen.
Simply great. Everything i need works great. Finally a kitkat aosp rom that given me everything i need. Flashed in TWRP on a t530 (wifi only) and running perfectly fine. Good job mate. If you want me to test anything on t530 just tell me.
Btw, otg works, so my usb keyboard is working.
Otg works, YouTube and twitch.tv works, BT works, rotation works, camera works, xposed works, everything i have tested works

Thanks! Glad to hear that it is working well for you. I believe the only difference between the SM-T530 and the SM-T530NU is the the NU has an IR blaster, which I haven't actually enabled yet. I need to figure out how to test that because I never use it. After i do that and post a build with IR, it will be useful if you check and make sure it doesn't break the regular 530. Those two from what I can tell are vary similar, its more of any celluar varients that I would be worried about, because this is build for wifi only..
Let me know if you find anything broken
I got this to work properly. I have one question though. Is there a way to get youtube working without having all the other GAPPS rubbish installed. I noticed that the tablet got slower as soon as I installed GAPPS. The tablet flies along without GAPPS installed and I only want youtube working without all that other rubbish bogging down the tablet.

Glad its working for you now
To be honest, I'm not sure - you could try copying the Youtube APK off of the device and then side-loading it on a fresh install without installing all of GAPPs, but I'm not sure if that will just prompt you to install all of them or not if you do that.
Are there particular use cases you are noticing are slower? I did not really notice any difference with or without GAPPs, other than the initial boot time as they were unpacked and installed. If there are particular situations that cause this, then we could dump some logs to see if there is something that could or needs to be optimized.

I have youtube backed up with all my other apps with Titanium Backup and when I try running youtube without GAPPS it fails and a popup states Youtube has failed to start (or something similar) and if I install the GAPPS I have which is older than the version that is needed it tells me that google needs to be updated. So then I update that and tried freezing the google apps I dont want or use but youtube fails.

The whole tablet is slightly slower with GAPPS installed. I've opened a gapps zip with WINRAR and removed some of what I dont want and only left whats needed for play store to run so it improved a bit.
Hi,
I didn't try it for now...
But thanks for the good work!!
For the Gapps, have you try PAGapps?
It has different package with a lot of options.
The smallest one should be around 136Mo. You can also remove some apk with a config file.
All other apps are available on Play Store...

I used an aroma based gapps. You can install only what you need. About using YouTube without gapps, i dont know if tubemate could do the trick. Use aptoide to install it if you dont like play store. Here is the link for the aroma gapps: http://forum.xda-developers.com/showthread.php?t=2547250

It has something to do with the lighting detection or some other initial initialization that I haven't figured out yet, but as a workaround if you toggle between camcorder mode and back it'll brighten up.

Tested and working fine. Is a nice workaround. I dont mind about this bug as I only use front camera for Skype and such things, but im glad this workaround is pretty easy and fast
Sent from my GT-I9300 using XDA Free mobile app
Hi Everyone,
I updated the original post with a new build. This build should fix the lighting issues with the rear camera the first time it is used. After I debugged the mode switching with logcat I was able to find out what the issue was. I also am working on reducing dependencies on vendor libs where possible by getting more of the modules that can be built from source building from source.
I've started exploring IR blaster support for NU users and I am continuing to look for a solution for bluetooth audio, but I don't have either yet. Stay tuned for future updates
If you already installed the ROM most times you should be able to flash over it, but if you see anything weird after, try wiping to confirm if its a bug or weirdness after upgrading (you can always nandroid before wiping if you're unsure and roll back if its not related to upgrading).
Please let me know if you find any issues. Include model number and if possible a logcat as well.
Enjoy!
Congrats starlightknight!
Anyone tried this on the SM-T530?
This is a port of OMNIRom 6.0.1 for the Samsung Galaxy Tab A 7.0 (2016) LTE SM-T285. OMNI is a minimalist ROM created by devs from the CM project.
5.1.1 is the best that you can get from samsung right now and it is not known if they plan to do any upgrades. I have absolutely no idea why samsung chose to stay with the outdated 5.1.1 mid 2016 when we already got 7.1 coming out. This custom rom is probably the best you can get if you want an upgrade from Lollipop. Performance on the latest build is also better, you be the judge.
Though this is stable enough that I use it currently as my daily driver, make sure you read the pending issues below and decide if this is acceptable to you before you flash this rom. This rom probably won't get much use out of some people until bluetooth is fixed.
Based off on OMNIRom 6.0.1 MOB31K sources which is based on Marshmallow.
For more information on OMNIRom and its features see their site here.

https://github.com/jedld/vendor_samsung_gtexslte.git
https://github.com/jedld/kernel_samsung_gtexslte.git
Update Dec 8, 2016
===============
* Fixed sideloading apks from internal sd card
* Fixed selection of preferred network mode
* Enable soft navigation bar (googe now on tap should work with this)
* Adjust heap settings
Works:
- Wifi/LTE/SMS (Some users report data intermittently not connecting, though toggling airplane mode on/off can fix it)
- Audio
- Graphics with glitches (minor screen tearing, blank screen showing up on overlays)
- Camera (works if a third party camera app is used. Does not work on the stock camera app)
- Bluetooth
- GPS
- Wifi Hotspot
- Incoming/Outgoing Calls
- MTP
Does not work:
- Calls (Incoming)
-- MTP (Browse Only)
- probably more (need testers)
Bugs/Known Issues
* Bluetooth A2DP streaming issues when both bluetooth and Wifi is on and network traffic is occuring. There are reports that this also happens in order ROMs, not sure if stock also has this issue.
* Screen turns upside down for a brief moment when turning off the device.
* Unable to select preferred network mode e.g. LTE, 3G, 2G (fixed 12/08/2016)
* Error while entering USSD code in the dailer
* Unable to tap to install apks for sideloading (see workaround below)(fixed 12/08/2016)
* Problems recording video
Other Notes:
- selinux permissive
Most of the issues are fixable, I just need more time and encouragement
SM-T280 Users: Unfortunately this rom would probably not work on it since the SM-T285 and SM-T280 have different kernels and slightly different hardware. I don't have access to this device so it would be hard for me to port it over. However I believe there are a lot of similiarities in the device tree that can be shared. If a dev with the SM-T280 is interested I can probably help.
Download
========
Remember flashing an unofficial ROM on your samsung device will probably void your warranty, Samsung representatives will probably not be able to help you as they are still stuck at 5.1.1 land as of now and have no idea how to handle a Sm-T285 that is running 6.0.1.
As always flash this at your own risk. Make sure you have a copy of the stock ROM so that you have something to fall back to, which is highly the case when using an experimental rom.
See DevDB download section for older releases. Or click below for the latest release:
Build Dec 9 2016
Note that this rom is pure stock and does not come with the Play Store or any Gapps, I suggest you download a micro gapps package separately and install it via recovery.
There have been reports that recent versions of open gapps don't work properly, it is advised to use older versions instead (e.g. open_gapps-arm-6.0-nano-20161109.zip)
Installation Instructions
==================
Perform a backup of all of your important files. This ROM is experimental and I will not be responsible for your loss of data.
Download the zip file and extract the tar.
Use Odin/Heimdall to flash the tar file to your device. If you are coming from stock oranother rom make sure you wipe first using TWRP. Coming from a previous version of OMNIRom for SM-T285 may not require a wipe, however please perform a wipe if you encounter problems.
Root and customization
===================
This ROM is a purely based on source and is not rooted out of the box. However you can easily root it by using TWRP to install the latest version of SuperSU.
If you want to customize this ROM and repackage it you may use this guide as a reference.
Workaround for apk install issue
=========================
Due to a possible bug with how sdcardfs is implemented in this device, apks downloaded externally and placed in external storage like Download show the apk is corrupt error when trying to install it.
however you can do a workaround by having root and doing the following:
1. Root your device (Download SuperSU and install via TWRP)
2. Download root file explorer
3. Using root file explorer move your apk to /data/local/tmp or create a folder under /data/local and move it there
4. Install the apk from that location and it should work.
Note that apps downloaded from the play store or install using "adb install" are not affected and works properly.

Thanks for releasing. Will definitely try it out if time permits.
I hope you will keep at this. This device needs marshmallow..
Great ROM! It is surprisingly usable, even at this stage of development, and feels far faster than stock. In addition to the bugs you mentioned, I also found out that apps will not install. Attempts at installation trigger a 'this package seems to be corrupt' error. Did anyone else encounter this problem?

No, via Odin. I even thought I had made a mistake at some point during the installation process, so I repeated it twice, once with Gapps, and once without, but the problem persisted.

Odin/Heimdall Flashable Zip: http://forum.xda-developers.com/devdb/project/dl/?id=21180
Installation Instructions:
If coming from stock, make sure you oem unlock first in developer settings. A full wipe is required so make sure you backup all your data.
Extract Zip and flash using ODIN or Heimdall. A TWRP recovery c/o @ashyx and repacked by me for the T285 is included in the package.
If you plan to install a GApps package it is recommended to do a full wipe so make sure you do that before you start using the device.
Note that this rom is pure stock and does not come with the Play Store or any Gapps, I suggest you download a micro gapps package separately and install it via recovery.
Special Thanks
===========
@ashyx - TWRP build
koquantam - work on the core33g provided an invaluable resource for porting the SM-T285 which is also a sc8830 device.

Many thanks for your hardwork jedld
build 20161104 is now available. GPS and bluetooth should now be fixed. Most of the hardware support for the SM-T285 seems to be working on a basic level, I am now attempting to use it as my daily driver.
Though bluetooth seems to work I haven't tested all possible bluetooth profiles yet, so keep your fingers crossed.
The remaining major issues are being unable to make/receive calls, Graphics overlay issues, being unable to play some video content in facebook (not sure if DRM related or Graphics related) and MTP.
There are also minor issues related to battery monitoring and screen flipping when going into low power mode.
I don't usually use this tablet to make/recieve calls so I am currently fixing graphics as a priority.
I use this tablet as a phone constantly so please get the calls working!! Great job so far!!!

1. Great job! In the course of testing, I bumped into a very odd problem; apps from the Play Store install just fine, but the apks I have saved on both the internal memory and the memory card will not. Has anyone else encountered a similar problem? How do I solve it? Thanks in advance. I installed the ROM via Odin
2. The WiFi hotspot is not working

Nice catch on the wifi hotspot.
For the apk installation problem, yes I am able to replicate it, turns out to be some permissions I incorrectly set for the filesystem, will investigate. However note that using adb install works fine.

I tried installing both the previous and current releases using adb, but for some reason, that didn't work.
I suspect the problem is at my end, though. I'll use another computer, see if that will solve the problem.
Thanks for the prompt response, and for the work that you're doing.
New build released for 11132016, main fixes are wifi hotspot, outgoing calls and partial MTP fix (still broken though).

1. Compared with the previous build, scrolling feels faster
2. A personal favorite; it is possible to enable softkeys without triggering system UI errors
3. Just like in the previous build, apks stored on the internal memory or microSD will not install if the ROM is loaded via Odin. Apps from the Play Store install just fine, though, and the problem completely disappears when the ROM is installed via ADB
For the Nov 21 release, all major issues have been fixed except for MTP. Graphics issues have also been fixed, expect a major performance boost, No promises but the user experience should be superior to that of stock, and I haven't even compiled for a release build yet. This release should be good enough as a daily driver assuming its ok for you to have SeLinux in permissive mode.

This is a port of LineageOS 14.1 for the Samsung Galaxy Tab A 7.0 (2016) LTE SM-T285. LineageOS needs no introduction, it essentially a rename from CyanogenMod due to naming issues.
5.1.1 is the best that you can get from samsung right now and it is not known if they plan to do any upgrades. I have absolutely no idea why samsung chose to stay with the outdated 5.1.1 mid 2016 when we already got 7.1 coming out. This custom rom is probably the best you can get if you want an upgrade from Lollipop. Performance on the latest build is also better, you be the judge.
I don't recommend you use this as a daily driver, but it should be good enough for some. Make sure you read the pending issues below and decide if this is acceptable to you before you flash this rom.
Based off on LineageOS 14.1 sources which is based on Nougat 7.1.2

- Bluetooth
- Wifi Hotspot
Does not work:
- video recording (sometimes works with 3rd party apps like open camera)
- GPS (no fix)
Issues
* Stability issues and some boot loops (Try to disable hardware GPS, or location services which may solve it)
* Wifi and network performance issues when both bluetooth and wifi is on and vice versa (needs confirmation from testers). I'm not sure if this problem also happens under stock. So if someone can give me feedback that would be appreciated.
* Setting alarms using the stock clock app will crash your tablet, use third party apps instead (this is a bug in upstream LineageOS and not related to this device)
Not essential but still needs to worked on
- HW encoders (06/26/2017 hw decoders now supported)
Other Notes:
- selinux permissive
Most of the issues are fixable, I just need more time and encouragement

See DevDB download section. Or get the latest version LINEAGE-OMS-14.1-20181117-UNOFFICIAL-SMT285-ALPHA.zip
For Older Versions/OMS builds see downloads sections:
All Downloads
Note that this rom is pure stock and does not come with the Play Store or any Gapps, I suggest you download a micro gapps package separately and install it via recovery.
There have been reports that recent versions of open gapps don't work properly, it is advised to use older versions instead (e.g. open_gapps-arm-7.1-nano-20161109.zip)
Installation Instructions
==================
Perform a backup of all of your important files. This ROM is experimental and I will not be responsible for your loss of data.
Download the zip file and extract the tar.
Use Odin/Heimdall to flash the tar file to your device. If you are coming from stock or another rom make sure you wipe first using TWRP. DO NOT USE twrp to flash these zip files, they are not configured for that.
Root and customization/ Build Guide
===================
LineageOS unlike Cyanogenmod does not come with root. However you can easily root it by using TWRP to install the latest version of SuperSU.
If you want to customize this ROM and/or repackage it you may use this guide as a reference.

Awesome work!
wow! Thanks jedid!
EDIT 2 amazing...wifi, cellular data for internet, sms, mms, calls all work (and no echo!)
as you wrote...mms (data) and internet (data) work after the 1st reboot
not yet installed gapps
slower than cm13 but an incredible start! (compare with tab s, s2 that even have official marshmallow and even nougat coming or already there for the tab s2 that have all call and data issues...this one is simply a great feat!)
only thing for some reason it will not automatically get the time and day from the cellular network
EDIT 3
a TWRP backup would not restore properly-android.phone.com errors (no root no gapps just basic setup)
strange thing when I flashed gapps (full not pico from Oct for 7.1) had all kinds of google apps force-closes and the network would not connect easily-it did but the errors never ended so I ended up trying to go back to the twrp backup which is when I got the android. phone.com stopped error (repeatedly coming)
am redoing the installation now (maybe was a bad twrp backup cannot know for sure)

Also happened to me. What I did was to rewipe after Gapps and it worked OK after that. Also set GPS to power saving
issues just reporting...updates
by rewipe do you mean wipe dalvik and cache? thx
edit
for time i just unchecked the auto time zone and manually selected my time zone...the time and day are now correct (but it is an issue..understand way early)
few things
the file manager seems to be missing the root option in general settings and prompts to add root permissions when the option does not show up (maybe because it has no CM root? and that an SU root is secondary? even if cm root is not set?)
the clock has the similar type of error as in cm13 (extreme only?)..try setting up alarm and it freezes when tapping OK to set alarm and then reboots (bootloops just as getting to android is starting message) (need to delete clock data in twrp)
no speakerphone but that has been absent anyway in cm13 and omni as well and the previous cm14
also problem connecting to the computer choosing mtp protocol the usb debugging and the connection option notifications vanish (even if set to always show) (think it does not do anything and remains in charge mode) through dev menu in settings it appears picture transfer may be set
the above are minor irritants given all the other things that are working! thanks
EDIT3
gapps 7.1 pico 20161024 worked no need for dalvik and cache wipe
Hello
Can you fix GPS? The Rom is nice but i really Hard ned GPS. Or give IT nö Chance to fix GPS?

I did a full data wipe after gapps, then it worked. Flashing gapps after going through a first boot seems to cause problems.
@jedid
Ok i hope IT give a fix for GPS. Then ist Use it as Daily.

the gapps 7.1 pico 20161024 worked without any dalvik wipe (not sure what happened earlier but suspect it was because i used a full stock although of the recommended timeframe of oct 2016 (7.1 only goes back to that month anyway)
Used it the whole day..calls text mms browsing
root explorer would not work (blank screen upon opening)-am using Fx explorer (root which does a great job anyway especially if pasting entire folders into system app/priv-app folders-sets the permissions automatically and correctly)
camera does not work known anyway (was not coming up on 2nd/3rd try)
lte signal similar to cm13 (omni is still fastest to get on and stick)
but at times happened at least 5 times and in static position that the internet signal would drop and then come back (so somewhat finicky there)
lag is there when opening certain apps-just sits there
happens at times when pressing ok button in say some app where you have to accept or reject
but alpha...known and/or expected
don't about bluetooth headset, netflix, audio sophisticated stuff..not into these/kept up with the times
youtube works no issues
odd thing if some app or function fails for some reason it says browser stopped...will have to note down which ones gave that error that had nothing to do with the internet browser (opera beta that I use works no issues as does the built-in browser...unless the data signal drops for some reason-then have to turn off and on the data/or even toggle airplane mode to restart the radio)
Just like your other alpha builds, this is really good; great work! Subjectively, the ROM feels quite fast.
The bugs I noticed were:
1. MTP is not working for me
2. Scrolling was smooth, but slow, and eventually got jerky over time
3. The tablet can be detected by other devices when Bluetooth is on, but it cannot receive any files
4. For some reason, CM Transfer - I did not test other apps that use the same approach to transfer files - is not working

Was this device made with Android 7.1 in mind? Some time last year, when I was trying to install a ROM using Flashfire, I noticed that this device seems to have two data partitions. After installing this ROM, the tablet reported that the total 'shared' internal memory was around 8GB, rather than the usual five-or-so gigabytes. I was very surprised

Didn't notice MTP wasn't working will take a look at it.
As for bluetooth it is still essentially broken in this build.

There are changes to how /data is structured but it is still one partition from what I know. It is still a mystery to me how it computes storage especially if you set your external sd card as adoptable, it could probably combine the size of both system and data in that report.

.now on a 2nd installation..TWRP backup restore runs into issues (twice now) (only on lineage not cm14.1/13.1/omni) get android.phone stopped issue.
mtp issues..yes in #4 "also problem connecting to the computer choosing mtp protocol the usb debugging and the connection option notifications vanish (even if set to always show) (think it does not do anything and remains in charge mode) through dev menu in settings it appears picture transfer may be set"
it shows up for selection but does not work (sits in charge mode)...I think the picture transfer appears to get set...will check again and try to restore the backup without data

anyone here having issues restoring from twrp backup (tried 3 times now each time it fails with looping android.phone crashes-muting the app then toggling airplane mode to restart the radio does not work) basically have to set it up and use it (the rom) but cannot try anything else (or have a backup that can be used in case things go wrong)...ran into the same clock issue as on cm13 (extreme only?) ...could not get out of the rebooting loop (tried deleting data for the desk clock) and then twrp backup would not work either
thanks
edit
I am able to restore without data (so have to set up again including supersu but at least it avoids the odin flashing part)
Seems the alarm clock issue happens on all LineageOS roms and not just mine. Their advice is to just get another app from the app store while they are fixing it.
Hi, thanks for continuing to work on this device.
Sadly, I have (or rather my granny does) a SM-T280... In the last thread there was someone who wanted to try to port to the T280, is there still work going on?
Also can I help? I am not really a developer, but a tinkerer; and I am fed up enough by the Samsung nonsense to try and help (as long as I can be reasonably certain to be able to restore the tablet to a working state even if I mess up, it's not mine after all^^)
SM-T285
:crying:
Just bought SM-T285 yesterday.
Last night I look in youtube on how to root my Samsung Tab A 7.0.
Me, as the stupid human followed the tutorial installing the img then poof! BOOTLOOP.
(looking for stock rom to flash it tru Odin)
Newbie here guys!
I know you can find ways to fix it.
We can wait..
Hello, can you port this for the T580? I kinda really hate CrapWiz

jedid, it seems the ftp issue is still there? as before checking or selecting the ftp option simply removes the toggle from the notification (does not show up until next reboot) and does not connect the drives to the computer
also not sure if you were looking at this issue but need to manually select the network time zone (does not automatically detect)
automatic takes it to GMT
The Unlegacy Android ProjectIntroduction
Unlegacy-Android started out as the OMAP4-AOSP Project. It was created in late 2015 in order to maintain a clean and organized place for pure AOSP support for various OMAP4 devices, such as the Galaxy Nexus and the Samsung Galaxy Tab 2 series. Over time this evolved to support more than just these devices, but still maintains its roots of supporting "legacy" devices that no longer receive "official" updates: hence Unlegacy Android was born. In our opinion, these ROMs are how the official updates would look.
On top of AOSP, we only include changes which are necessary to support the hardware, be secure, and get acceptable performance. Current features for flo/deb include:
- Linux kernel 3.4.y merged in (currently 3.4.108 - mostly security patches and minor bug fixes)
- BFQ IO scheduler (official kernel 3.4 release), set up so GUI processes have the highest priority
- F2FS support from kernel 4.9 (for /data only!)
- SELinux in Enforcing mode
Installation
If you're planning to install GApps, be sure to read the second post!
Aside from these, installation and upgrading is no different than on other ROMs.
Problems
- No known issues for flo/deb yet.
If you notice anything, be sure to report it in this thread. Stability is our main concern. While I'm kind of busy, I usually read the thread and acknowledge the bug reports, even if I don't reply directly to them.
Downloads
See: http://builds.unlegacy-android.org. Our automated builds ensure that we always have the latest Android security patches merged in, without having to manually start and upload builds
We will have a built-in OTA updater (just like stock) soon (it's a work in progress)
Information about our experimental builds and progress you may find here.
Features?
There isn't much to say here - this is AOSP, if you install GApps, you pretty much get the same thing that's running on the Nexus devices (see the second post). The aim of this project is to create a fast and stable ROM - although, one could use Xposed to add extra features.
As usual, feedback is appreciated

GApps
If you want to install GApps, we recommend Open GApps Micro.
An important note: as this is a pure AOSP ROM, installing GApps tends to be problematic: in order to try to avoid installation issues, be sure to install GApps immediately after installing the ROM, before booting the system for the first time. If you experience any issues with the Google applications, be sure to go into Settings -> Apps, and grant every permission to every Google application - most importantly, Google Play services.
In the case of an upgrade, be sure to re-install the GApps package, as upgrading wipes /system. You shouldn't need to re-set the permissions afterwards.
Stock-like setup
Disable the following built-in (AOSP) apps:
- Android keyboard (once you installed Gboard)
- Browser
- Calculator
- Camera
- Clock
- Email
- Gallery
Install the following apps from the Play store:
- Google Photos (https://play.google.com/store/apps/details?id=com.google.android.apps.photos)
- Calculator (https://play.google.com/store/apps/details?id=com.google.android.calculator)
- Chrome (https://play.google.com/store/apps/details?id=com.android.chrome)
- Clock (https://play.google.com/store/apps/details?id=com.google.android.deskclock)
- Gboard (https://play.google.com/store/apps/details?id=com.google.android.inputmethod.latin)
- Gmail (https://play.google.com/store/apps/details?id=com.google.android.gm)
- Google Calendar (https://play.google.com/store/apps/details?id=com.google.android.calendar)
- Google Camera (https://play.google.com/store/apps/details?id=com.google.android.GoogleCamera)
- Google Now Launcher (https://play.google.com/store/apps/details?id=com.google.android.launcher)
SafetyNet
The ROM should pass SafetyNet after installing GApps, without anything else. Keep in mind that installing extra stuff (SU, ...) might make it fail!
Rooting
You can flash the latest Magisk to get rooted.

I simply use Darker for night time playing in the bed personally, I reduce brightness to 65% and apply a slight yellow tint. When most websites are white, theming the framework wouldn't matter that much anyways... and we kinda want to feel like a factory image (no dark mode in them either)
@Ziyan
It's a pity)
The rom itself works fine. Good job)
@Ziyan Thanks for your efforts on these older devices. I've used your work on both Gtab 2 and Grouper before I sold them. I just downloaded 0324 builds for Flo and Hammerhead, neither one matched the MD5. I just downloaded Flo again but still no match. I haven't tried flashing any of the roms yet but figured I'd let you know.
Also, don't know if you use Netflix but it's been a problem getting a current version of the app working properly on ANY Nougat rom for Flo. Without any modifications, the Netflix app will load and give you an option to download and watch at a later time. However, if you try to just do a normal streaming of a movie or show, it will give you an error 0013. As is mostly the history of Netflix, it appears to be a drm issue. @Startrek852 was able to compile a zip with drmblobs that will eliminate the error 0013 and allow normal streaming but you lose the ability to download and watch at a later time. Although I don't use Google Movies, it's my understanding that it will not work if you flash the drmblobs.
Anyway, just wondering if "in your travels" you've heard of this Netflix issue and might possibly know of a proper fix. Thanks again.

Play Movies works perfectly, so I'm not sure how to debug that either ways - can look into that zip later on.

Very weird on the MD5 thing, as mentioned I downloaded it twice and on a desktop PC so it shouldn't be a mobile issue??? I'm gonna' flash it later, will report if there's a problem.

Updates come out every day ...?)
And why the cache is not f2fs?
I'm sorry that there are a lot of questions. I just made this rom basic and I want to figure it all out
p.s. That there were no problems with gapps - you need to restart the recovery after flashing the main rom
have volume wake option?

Our little build server likes overdoing its job and building even if the changes don't affect flo - until this is fixed, it's enough to update every 3-4 weeks or so to get the security updates, unless I make an announcement here about a change
About /cache f2fs: there's simply no point, as that partition isn't actively used by the system (other than maybe OTA updates). I usually don't support it, as it can lead to more complications than what it worth...
@Ziyan
Thank you for your reply)
I really like the way the rom works.
Only have to use a lot of additional tools to at least somehow expand the settings)))

Install via TWRP.
I'm not responsible for any damage to your device of any sort.
By flashing this you take responsibility of anything that happens.
Process at your own risk!
If you want to check firmware - please make backup. Better to store all partitions, at least efs and may be modem.
Instructions
1. Install twrp
2. Download the zip(s) - firmware and Google Apps additional package (optional)
3. Backup all partitions (it least efs) and store somewhere - it need to do - because you can loose imei
4. Full wipe all
5. Flash firmware and gapps
Work
almost all

I am getting 'There's an internal problem with your device. Contact your manufacturer for detail.' error on every reboot. I've flashed the 'BL_T825XXU3CSH9_CL16530048_QB25611745_REV00_user_low_ship_MULTI_CERT.tar.md5' bootloader but still facing the issue.
See the screenshot for error message.
Camera is not working

Hi there,
do you have any intention to include palm rejection on Q?
It's the only missing feature on LOS...

Do custom ROMs have to have palm rejection added? It's not normal feature?
This would be good to know as I got this device to use the pen!
I notice that screen is very hard to wake up. I have to play all buttons in random combination to be able to bring up lock screen. Once it get unlocked, everything works find.
I did once get system UI locked error. I have to push all buttons to force it reboot.
So I tested this rom on my T820 Wifi and in my opinion it works pretty stable, except of some issues I recognised:
- Saving pictures does not work. The pictures I get are scrambled.
- sd cards in ntfs format not working
- Palm rejection is not working
- ed xposed causes boot into download mode
- screen wakup is sometimes slow
- Viper4Android is not working
- Speaker only working on one site (right)
- it's not possible to rename SD Card or uninstall any system app like mail-app via root
- Netflix is not working
- Not possible to activate a custom notification sound
- Adaway only working with systemless host activated in magisk
- trying to use miracast causes a complete crash of system ui and makes a reboot necessary
- digital wellbeing randomly fc if settings menu is open
- sometimes hardware buttons stuck and i have to wait 5 sec until I can use them again
Thanks for your work!
*update: On second build same issues and camera just force close, now
did anyone figure out how to get the camera to work. It takes pictures but to view them they all look scribble.
does this rom work with the T825Y?

Just try it. I think the specifications are the same like T825.

Not working on second build for me
Now for the *REAL* question, does this ROM cause graphical glitches when you run a 3D load and heat the processor up to 100c?! That was my experience various unofficial LOS16/RR based Pie builds. I get temps in the worst case up to 97c under extreme load on the stock OneUI ROM, but normally it is way LOWER. Could someone (with the performance level in the power settings set to max) test games like https://play.google.com/store/apps/details?id=com.PnA.Offroad and some heavier ones for an extended period of time, and maybe some benchmarks (AnTuTu, 3DMark, etc...) while watching the CPU temp and General SoC temp with a temp guage overlay (like the one in the paid option on DevCheck).

Is there any chance, that you compile Havoc OS 3.0 for our Device?
Thanks in advance

Don't expect that anything on this rom will fixed soon.
Always the same with this dev. He releases a build with issues, then he ignores all issue reports and only releases sometimes a new build with security updates and nothing more. I wish a had wait a little bit and bought a tab s5e, because it seems to be the only new Samsung tab with fully working custom roms and palm rejection.
Better you use stock rom for tab s3.

same here
There is something that I cannot understand. The users say that there are problems with the ROM but OP says there aren't...

Not sure if answered but I fixed this by:
Copying the complete line ro.vendor.build.fingerprint.................. from the /system/build.prop file.
Paste replacing the line ro.vendor.build.fingerprint.................. in the /vendor/build.prop file.
These files crosscheck each other looking for this line. The files must be from different builds.
