LineageOS is a free, community built, aftermarket firmware distribution of Android, which is designed to increase performance and reliability over stock Android for your device.
LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.
Instructions :
Download the latest build and gapps
Reboot to recovery
Flash the latest build and gapps
Reboot

Reporting Bugs
DO NOT Report bugs if you're running a custom kernel or you installed Xposed or Magisk
Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
If it is a random reboot, grab /sys/fs/pstore/console_ramoops. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log
Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.

Couple notes.
1. I don't have firmware update zips yet. Unfortunately, I think the different models will need different firmwares. Though, I may still be able to make that one larger zip. Not going to happen real real soon because:
2. I soft bricked my darcy (2017 emmc model). The official build didn't boot for some reason. And using the controller to get to fastboot isn't working. I have a message out to one of my contacts seeing what can be done. The official build works fine on my sata model, and my side builds worked on both. So, I expect it was just a fluke, but if you're on the newer emmc model, might be a good idea to make sure the controller works in fastboot before flashing.

So this does work on the Shield Pro 2017? I already have unlocked bootloader and I can boot TWRP. Also have Supersu installed. Also is it rooted? Sorry if this was already answered in the thread.
thanks

Any big bugs?

It works on all models, and there is no difference between the old and new pro models. Su is not included, same as other Lineage releases. But there is the official su addon zip on the download site.
Big bugs? Guess I didn't copy those from the old thread. Only thing I know of is Netflix. Having so much trouble making it happy... Finally gave up and pushed official anyways. Won't even run on most models, and while it does run on the new emmc model, the video stops playing after a few seconds. The only other thing I know of is the annoyance of pairing: have to have a controller hard wired on first boot. Then after the setup wizard you can pair a Bluetooth controller and everything works fine.

thanks for the reply. and I take it Su is flashed in TWRP? Do i do a factory wipe in TWRP before flashing Lineage?

Yes, Lineage, su, and gapps are all flashed in twrp. You will need to wipe data and caches when flashing Lineage for the first time. Internal sd can be persistent, though.

great thanks. Will report back how it goes when I try it out.

Is it full play store and what interface?

But is gamestreaming present in this?

This is Android TV and uses the ATV store. I will make an unofficial build of tablet mode sometime in the future.
Game stream works fine. I test with Geforce Now, but game stream uses the same thing. Just install nvidia games and it will work.

Gave this a try. It flashed fine. Flashed Lineage, gapps and Su. All seemed to flash without issue. Only problem was user error. I flashed the wrong gapps. Should have flashed X64. after reboot couldn't see Google Play Store. I was able to pair the remote and the controller with very little problem since I already had a wireless keyboard attached. I went back into TWRP to flash the correct gapps and that is where things went south. TWRP for some reason was having a problem with mounting partitions. I couldn't even restore backups I had in TWRP. All this I'm certain was a result of something I did. I was able to finally get back in and restore a previous backup. Scary stuff though. Gonna have to pay closer attention when I try this again. At one point TWRP even said no OS installed. Everything seemed to work as it should other than my few fumbles. Looks really promising. Great work
thanks again.

@Steel01 so the original Shield Controller is working? I'm asking this because I was not able to pair my shield controller with my shield tablet (I'm using your official LOS on shield tablet too).

No it doesn't. The old controller is wifi direct, not bluetooth. There is a way to manually pair the controller using adb or a terminal emulator, but it's not at all user friendly. The new blocky controllers are bluetooth.
I'm still working from time to time to try and get the official pairing app to work for the old controllers, but there's some hook loading code that Nvidia hasn't released yet and I haven't quite reverse engineered either.

Thanks for the reply. Ah then this is a show stopper for me I've only the original shield controller, and I need it in order to use my shield tv
Is root required to manually pair the controller? thanks

any ETA on tablet build?
thanks for your work here

I made the build Saturday night, but didn't get around to testing it. Still fighting with my darcy. It boots unofficial builds, but croaks on the official one. And fastboot is acting extremely flaky. I may get to testing a tablet build tomorrow night, but no guarantees.

Amazing! I think a lot did't know about this!

Is there a link anywhere to a description/guide of this manual way? I might be willing to give it a try. Also, is the link procedure needed only once, or every time?

Can this be flashed straight from Marshmallow or do I need to upgrade to official Nougat first?

Hi all, after a great effort and lot of work finally i got cm9 compile from source working in my s7 model 105.
this is a more stable version it still has some bugs that i'm trying to solve, help is welcome.
I used kernel from jotamj from another forum and i use asturel device files to get it started, asturel files is for the slim so i had to made some changes in the files, thanks to them.

my s7 model=105, it may work on 104 and in 106, probably will not work on s7 slim
what works:
-wifi
-bluetooth
-audio
-gps
-google play (solve, install gaps file)
-streaming (must install flash player 11)
do not work:
-camera
-usb mount on pc
how to install:
first do a backup, IMPORTANT , backup first ( in case same thing go wrong)
copy file zip to sdcard
boot on cwm and install zip file
reboot and wait 4 to 5 minutes, if anything goes wrong restore from backup.

Huawei isn't to blame I think. I don't think there are many QSD8250 devices that made it past Gingerbread. Acer (Liquid, Liquid E) and HTC (Desire) left their devices on Froyo. Dell (Streak 5) moved up to Gingerbread.
I have given my S7 away to a family member and won't be changing the firmware, but thanks for putting this together.
That's a weird looking ro.build.fingerprint you have there. Fix in cm.mk for build. Play Store also freaks out if you have a date too far from the present.

Hi xaueious, when i bought my s7 it came with android 2.1, some time after huawei lunch android 2.2 for asia, i had to wait for a suedish user to hack it and lunch it for europe, they could lunch android 2.3 but they where not interest, that why i said huawei suck, other manufactures realeases updates for they clients, but not huawei.
the fingerprint of the build has to do with the system i came up with to test things, i started with asturel base devices files but that is for the slim, so i had to test what option worked or not, it took dozens of test and tries, to get it to work.
i got the google play problem solve, see post 1, and streaming to
I'm close to get a 100% working rom.
test it if you can, and help me solve the bugs if you find any, enjoy.

I installed your rom on my s7-105 but now it's not starting proper anymore. I see the word ANDROID and I can hear a small click every second but nothing more... what's wrong?
---------- Post added at 04:07 PM ---------- Previous post was at 03:53 PM ----------
After a re-boot I get the message "Update failed! Please retry!" No matter which key combination I try (vol+ & power, menue&green&power, oder vol+&vol-&power) this is all that I get!!!!!!! HELP PLEASE!!! What can I do now?????? How can I get back into CWM to reinstall a rom??????
after some try & error I found out that with the key combination back&red key & power I can make the device to boot, I see the words Ideos and later android again but that's all. It's not going on. I have no idea how I can install an older rom now....

Sounds like a boot loop. What ROM did you come from? You should be coming from Android 2.2, not 2.1.
Here's a list of stock firmware to use: http://johnnyparanoia.blogspot.co.uk/2012/04/huawei-s7-tablet-firmware-list.html

To be honest, I can't say it for sure which one I had. In the status menue it said "2.1 update 1" Whatever this means. I had problems to install the clockworkmod I finally found this ROM: rom tri_zet. With that I could install clockworkmod and reboot the tablet into recovery mode. Then I installed this rom here and run into the problem.
Last night I finally managed to install the official swedish ROM 2.2.2. With that my tablet is running again.
Do you think with that one I could make another try to install this rom now? How can I install the clockworkmode now? Maybe the tri_zet rom was the cause of the problem...

Hi grka, i tryed tri_zet but i didnt liked so i used the swedish ROM 2.2.2 until recently.
My advice install cwm 6.0.1, backup and then when install, clear cache and data, then intall my rom it should work
If you get problems again restore from bacup.
1º install the rom, let it boot, after sucessul boot install gaps to make goople play work.
If you need more help ask.

2-connect s7 to pc
3-extract the zip file
4-in a dos text console inside the dir where are the files execute: "fastboot flash recovery s7-recovery-v601.img"
5-to reboot "fastboot reboot"
to go to cwm, with device power down, menu+call (green key) + power on

Hi threader, i didnt save the img file, so i compile one today with my 53 source files, here is the link: https://docs.google.com/file/d/0B9OIKoN0knUtSXU5Tm9XZUYzYms/edit?usp=sharing
one question. do you know how i can have (make) a system.img file in ext2 format, insted of a yaff2 ?
Hal_2000
I think there is a flag to make the userdata ext4 , but do not make it ext2! It is prone to dataloss if not unmounted properly, it is better to compile in ext3 and 4 support in to the kernel. But i believe if im not mistaken i have seen options to make ext images in the codeaurora sources
Under BoardConfig.mk, TARGET_USERIMAGES_USE_EXT4
Relevant: https://groups.google.com/forum/?fromgroups=#!topic/android-building/wdV3GIe_XC4
The update.zip should be sufficient for most users. Shouldn't need to provide fastboot images.
build/core/Makefile contains the rules to generate the boot, userdata,
and system images. The choice of file system for the two latter is
determined by the setting of the TARGET_USERIMAGES_USE_EXT[234]
variables, so to get ext4 for your system and userdata images you can
say
TARGET_USERIMAGES_USE_EXT4 := true
in e.g. BoardConfig.mk.

For the usb mount, I don't really know how to fix this at all, but the is the Acer Liquid similar? https://github.com/thepasto/liquidCM_devicetree/blob/master/acer/liquid/BoardConfig.mk
BOARD_USE_USB_MASS_STORAGE_SWITCH := true
TARGET_USE_CUSTOM_LUN_FILE_PATH := "/sys/devices/platform/msm_hsusb/gadget/lun"
(lun path needs to be fixed to match S7. I remember changing this when I kanged recovery)

I'm not an expert at CM. I just worked on building one very specific platform and know where some files are... But from what I know...
For Android platform: http://elinux.org/Android_Build_System and https://android.googlesource.com/platform/build/+/master/core/build-system.html
If you modify specific packages, mm and mmm are nice tools to use. For building, make otapackage does a lot more crap than just making the target images (make bootimage, make systemimage). Enabling CCACHE is supposed to help with build speed too. Also consider stripping the unnecessary languages during development, and stuff builds a lot faster (PRODUCT_LOCALE flag), because a ton of time is spent building together strings.
Originally build options are mostly in /build/. CM has some new options in there, but I am not sure if they add new ones elsewhere. Other things to pay attention to are the .prop options that CM has added. Those things are littered all over and don't have documentation, but at least git commits are easy to follow.

Hi, thank you,
Just in case someone else as same question, TARGET_USERIMAGES_USE_EXT4 in cm9 only acepts ext4 no ext2 or ext3, i tryied all tree options.

Hi, kosmasgr, the audio same times gives a click, is a little bug, the device source i used is from asturel and his files are for the slim version, i'm trying to fix the camera its more critical then the audio bug.

The click is a problem from kernel that Huawei provided for 2.2.2. Kernel source is generic for both version fat and slim.

[RECOVERY] [OFFICIAL] TWRP for Shield Android TV

Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.
DOWNLOAD:
Most devices can be updated quickly and easily within TWRP if you already have version 2.8.4.0 or higher installed
1) Download the latest version from our website on your device
2) Reboot to TWRP
3) Hit Install and tap the "Images..." button in the lower right
4) Browse to the location of the TWRP image on your device and select it
5) Select recovery from the partition list and swipe to flash
OR:
You can find more information and download links on our website.
SHIELD Android TV 2015/2017 direct link
SHIELD Android TV 2019 direct link
BUGS:
If you have found a bug, please consider posting it to our github issues log. It's pretty much impossible for us to keep up with the more than 40 threads that we have for the devices that we "directly" support. If you have a significant problem that cannot be answered in this thread, contact us via our website, or find us in our IRC channel below. If you see someone that's struggling, feel free to point it out to us. We need your help to help us keep track of all of our devices! Thanks!
SUPPORT:
Live support is available via #twrp on Freenode with your IRC client or just click this link.
NOTES:
Due to the lack of a touchscreen on the device, you will need to have a mouse plugged in. A keyboard should work as well for typing input.
KNOWN ISSUES:
Cannot display at 4K. There have been a few reports that some 4K TVs wont display this recovery, but others will properly switch to 1080p mode and work just fine.
Build and device page will be up shortly. Got some fun recursive references going on here. Build is live.
Anyways, I know, I know, it's about time, right? Just haven't had too much motivation to work on this device. As powerful as it is, it's been a bit of a pain to work on. True built from source custom roms are still crippled due to hdmi audio not working, etc. But afaik, this recovery is 100% working, no problems. But if you find anything wrong, please let me know here.
Hmm, it seems adopted storage still isn't getting mounted correctly. The "Micro SDCard" selection is only 15 MB. Also, it's not picking the correct time for backups. The terminal shows two errors when typing "ls -l":
__bionic_open_tzdata: couldn't find any tzdata when looking for CST6CDT,M3.2.0,M11.1.0!
__bionic_open_tzdata: couldn't find any tzdata when looking for posixrules!

Really? Blast... I pulled the same fix that worked on the tablet, but didn't actually test it on this platform. Guess I'll have to do some tinkering. Not a whole lot of time for a couple weeks, though.

Does this support 4k TV finally?

Doesnt look like there is.
But it seems like vegeta has stumbled upon one way for now, indicatative that the issue may be from the direct hdmi connection from the shield to a 4k tv. Maybe theres a cheap 4k compatible hdmi splitter/switcher/combiner out there or perhaps one you own already, that can be tested depending on your urgency for twrp
Alas this doesn't even work on my Monitor with an HDMI to DVI converter. Actually it does work, once it finishes booting up that is. But for TWRP it's a standard Black Screen then.
Is it really that hard to code TWRP to output a 4k.. barring that a locked 1080 signal? This all said it worked very well on my Old Man's FHD LG TV have the command, and a moment latter it was there. So installing SuperSu successfully, and a full boot latter I packed it back up, and took it home with my again.

Update isn't released yet. So nobody can say for sure.
From what I thought I knew about Android, the Recovery Partition is fully independent of the OS One. This said from what I read about Nougat, where we used to just have the One OS Partition, from Nougat going forward we'll now have Two. An active One, and the other that will be used for active updates. This should be interesting for those on low spec Devices such as the 16Gb Shield. As the Android OS has traditionally taken about 4Gb of Storage. So can we expect that to double now?
About the only thing that could theoretically happen is that the Update overwrites the Recovery Partition. But I don't think this will be a problem.
But, to pass along some helpful info which I made an enquiry about in a different Thread. Once you have flashed TWRP as your recovery, and as far as I can tell you have to have it installed, and not merely loaded from a fastboot command line. You can simply install SuperSU again. (And you will have to do that again anyway.)
Which could be a problem if your like me, and stuck with just the One 4k (2160p), TV. Then this is a more round about way to reinstall SuperSU again after the Update.
Just do the following:
Login to your shield via ADB..
Code:
$ adb reboot recovery
$ adb shell
$ twrp install /sdcard/SuperSU.Zip
The a/b system partition thing is only being done on new devices. We will not repartitioned and lose space due to the upgrade.
The current twrp works just just fine with N ROMs. The worst thing you will see is a couple errors saying a log command isn't found when installing the update. This happens on all ROMs, all devices. It isn't fatal and can be safely ignored. Other than that, everything will continue to work as before. Flashing, backup/restore, etc. No problems at all. No, I haven't seen the official update yet, but I've done some work with cm-14.1 which is the same core stuff.

this dosent work at all on the new shield. just reboots after flashing then it reflashes stock recovery
Well I guess the question is does the "new" Shield TV (Slim), actually count as a "New Device"? That supports Google's new a/b System?

so fair the only thing that has been discovered with this new "model" is the usb identifiers have changed abit.
Hmmm... Kinda surprised it doesn't boot at all. Maybe the dtb and kernel changed enough that the newer bootloader balks at them. I won't have one in hand until probably next week. Once I do, I'll make something work.
Previously I would have said no, darcy doesn't have a/b updating. But... The more I look through the code drop, the more it looks like it actually does. But I won't be able to confirm until I got my hands on it.

heres the 2017 5.0.1 image if this helps http://ota-downloads.nvidia.com/ota...-full_ota-1749719_832.2408.20170116175313.zip
Well, I'm still waiting on a darcy. I hear it's supposed to ship this week. Sorry for the wait, but it's hard to do any development without the device. That or the update for the original 2015 one I've already got. Once I get my hands on something to test with, I should get something out pretty quick.
And yeah, the ota link helps. I went and compared a bunch of stuff and I think I have it ready to go, just can't test it yet.

Thanks @OldDroid for all the efforts.
I have used all 4 and all are working awesome, especially RR beta 2.
Awesome work....
What about the deep sleep issue on 950?
Will it be fixt in the future?
Hey guys, I have a spare mate 8 which is actually on build 829. Followed the instructions to the letter on Openkirin website, on RR beta 2right now,. But each time I reboot it, it says that decryption is unsuccessful and to reset the device. Is this normal?

Yes, decryption problem remains with OK ROMs. You need to either decrypt with twrp or with fstab through adb shell. Once done, you won't get it again till you flash stock room again.

Thank you buddy, basically same issue I ran in to when I tested AOSP a while ago except that ROMS are now more elaborated and functioning smoothly.
I try rr beta 2 and omnirom but i have only one sim (sim 2) sim 1 does not exist.Nice sim 2 does not work with all operators. For the idea?
For everyone else who has been struggling with the decryption issue, I finally figured out how to get OpenKirin's LineageOS image to boot without first encrypting. You lose FDE in the process (a tradeoff I'm willing to make to get a working phone).
1. Start with stock EMUI 8 and a stock recovery. You can get EMUI 8 using the HWOTA packages. If, anywhere in the process you make a mistake, you can restore EMUI by flashing the HuRUpdater zip.
1a. Boot into EMUI 8 to make sure it is intact. You may need to run a factory reset from the recovery (the complete, stock recovery which you can reach by holding Power + VolUp. Do not reset from eRecovery.) Once you see the language select screen you can be satisfied that it works.
2. Boot into fastboot (power off, hold VolDown and plug into USB).
3. Flash your OpenKirin ROM of choice:
Code:
fastboot flash system openkirin_ROMNAME.zip
4. Exit fastboot and immediately perform a factory reset from stock recovery, just like the OpenKirin instructions tell you to. Do not boot into the OS first. For me, the factory reset appears to fail. I ran it anyway just to be sure, and it does seem to make a difference even if it fails.
5. Once the reset is done, return to fastboot.
6. Flash this version of TWRP (originally for Mate 9):
Code:
fastboot flash recovery_ramdisk twrp_mate9_0.1.img
7. Boot into TWRP recovery: run
Code:
fastboot reboot
, unplug the phone, and hold down VolUp until the logo appears. (You have to be quick.)
8. Once in TWRP, load up an adb shell and remount /vendor with write perms:
Code:
mount -o remount,rw /dev/block/bootdevice/by-name/vendor /vendor
If your devices differ, use
Code:
df -h .
to see what the device name is.
9. Alter the following files, removing any boot flags that say "avb" or "forceencrypt":
Code:
/vendor/etc/fstab.f2fs.hi3650
/vendor/etc/fstab.ext4.hi3650
Make sure the comma-separated lists stay valid.
10. Save your files, and tell TWRP to reboot to system.

I also had that problem, a developer told me its because of the cdma modem, which is in the AL10 variant. Max connection i got was Edge.
So im back to stock an wait till they fix that problem.
Are these projects working for mate 8? I see that the rom has not been updated

yup this is for Mate 8..there are few peoples already tested it but seems like there are still got few bugs like signal and etc. i'm waiting for a new build and will test it.
I'm another that has tested LOS, RR, and OR, and all have the issue with not getting any SIM card signal. Obviously I can't use, as a smartphone without the phone, isn't that smart.
Keenly hoping this gets resolved, as I certainly like the look of these ROMs.

I've tried from NXT-AL10 b829 stock ROM, then loaded each of the OpenKirin system images with the same result.
Are you saying if I flash DL00 stock ROM (b829?) first, then the cellular signal should work?
If so, I think DL00 uses the same base except for a different "cust" partition. Perhaps I just need to flash the DL00 cust partition?

Did you flashed cust after upgraded to B596?if you noticed that you don't have signal or no service at that time?

Yes, and signal was fine at B596. Signal is also fine on either stock b829 or KangVIP b828/829.
Firmware Finder's been offline, but looks like it's coming back online soon, so I'll try installing DL00 b829 stock ROM, then OpenKirin, to see if that helps.
(I tried flashing just DL00 b829 Cust.img yesterday, but it didn't seem to make a difference.)
For those that do have working signal on OpenKirin, what full base stock ROM did you come from? i.e. b829, DL00, AL10 etc, and which country region C00, C92, C17, etc?
Hi, looks like I am having the same signal issues as every one else on NXT-AL10. Have flashed back to stock EMUI 8 for now after hard bricking my device and using Dc-Phoenix to recover by shortinng out the testpoints.
Like every one else have been looking in to possible solutions. After booting in to open kirin roms and looking in to phone info in setting I noticed my IMEI was blank. At this point flashed back to stock after hard bricking and loaded in to HCU-client to repair fortunately this was not the case and IMEI was intact.
So digging around other Huawei boards I fond this maybe a possible solution to signal issue. Don't have time to try just now will let you know how it goes.

Tried this, and confirmed that my IMEI is also missing from OpenKirin, but after changing the local.prop file and rebooting, it was worse. Rather than the SIM being detected, but having no signal, the SIM was no longer being detected at all (slot showing as empty). Tried OpenKirin RR.

LineageOS is a free, community built, aftermarket firmware distribution of Android 9 (Pie), which is designed to increase performance and reliability over stock Android for your device.
LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

Reporting Bugs
DO NOT Report bugs if you're running a custom kernel or you installed Xposed
Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
If it is a random reboot, grab /sys/fs/pstore/console-ramoops and /sys/fs/pstore/dmesg-ramoops-0. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log
Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.

with the abl.img the fastboot has go in the system no mtp modus
can you both abl.img without fastboot and abl.img the fastboot did not combine so we have fastboot but can still switch to mtp on system ?
Ps
with the abl.img the fastboot makes it possible for me every few minutes the sd card out but then again nen recognized
After a little trial and error, I finally got it installed on my Chinese version. Thank You! Running through the setup now. Once again, Thank You

Yes, with the Fastboot abl.elf ,MTP on System is disabled for whatever reasons......
But if I'm honest, with TWRP installed if you don't have the need to have fastboot, just keep stock abl for MTP and TWRP to flash anything.
Beside you can just use the AxonTool to get fastboot abl without problem.
I'm also leaving here a link for the TWRP Flashable Fastboot abl in case anyone wants it.

Hi!
I have two problems with the rom.
The first one and most important is, that it sometimes just stops at LOS boot animation and I have to flash the entire rom and gapps.
The second one is that LOS recovery always overwrites TWRP, is there any option to avoide that?
Thanks!

Not sure about your first problem because you have not provided a log (I haven't ran into that issue yet). It could be something you have installed or some option causing an issue. The second problem is something that cannot be stopped. Newer devices don't have a recovery partition it's packed into the boot partition. The ROM provided a boot IMG so TWRP isn't replaced it's just not part of the boot.IMG that's being flashed. After you flash the ROM, flash the TWRP installer again (this cannot be changed)

Installed and working on 2020
I live in Canada and couldn't order an Axon10 anywhere here, so i got one from China. It is the A2020 not the G or the U. I managed to flash TWRP and this LineageOS ROM on it successfully, except for one detail.
I can't seem to get the mobile data networks to connect. I can make calls and send and receive texts, but no data networks. I've tried flashing the original modem, resetting the cache, and reinstalling the rom. I can't seem to change the APN settings either as they're all greyed out.
Any advice would be appreciated.

I too have the Chinese version. I was on Lineage, but went back to stock. even though there are some annoyances with the Chinese rom, there were some issues with the Lineage rom. Such as, No face unlock, FP scanner or wireless charging don't work and sound was rather low. I'm sure all these issues will be worked out in time.

I have the 4G version. I just don't personally like light modes, so I have kept mine BL unlocked so that I can theme so that most apps are dark, but the other annoyance I have with the Chinese rom is the over agressive memory management that constantly shuts down Google Assistant. This causes me to constantly have to reset it. That is why I was asking if anyone had the capabilities or knew of a rom that had Chinese setting, but system images with Google Play. I have also tried eliminating Z-assistant, which seems to manage things, but Google Assistant is still shut down. Are you knowledgeable as to which app/service might be responsible for shutting things down?

Fp is almost impossible. After a few weeks we finally got ZTE audio changes it may not be the same for fp. I'm not sure who makes the decisions but they modified the default Android service for fp. You can't really do that it's against vts. I've tried myself to do the same and the build give a big warning. It's not impossible to get it working, I just refuse to go that far to get something working when it could have been done differently.

This causes me to constantly have to reset it. That is why I was asking if anyone had the capabilities or knew of a rom that had Chinese setting, but system images with Google Play. I have also tried eliminating Z-assistant, which seems to manage things, but Google Assistant is still shut down. Are you knowledgeable as to which app/service might be responsible for shutting things down?

Could you grab a logcat? Since the modem is working it could be the network mode is different for this device even though it's the Chinese one.

What's posted below is a work in progress, but it should suffice to unblock efforts to build custom ROMs for this inexpensive tablet. Many thanks to @mehanik6 on 4PDA for blazing the trail.
Notes:
The current process requires you to reset to factory defaults to remove file-based encryption. Remember to backup your data!
Custom kernels are specific to OEM releases, and rely on the latest posted kernel source.
This is unofficial and unsupported, so the usual caveats apply. Since we don't mess with the bootloader, you should be able recover from any problems...but nothing is guaranteed.
Not working:
Support for file-based encryption

What about rooting with Magisk?
These images are not supplied pre-rooted with Magisk, since it's against the terms of use laid out by Magisk's developer, John Wu. To root the TWRP image yourself, simply use Magisk Manager to Select and Patch a File. More details on this process are available from @ianmacd's topic for the Galaxy S10 series here.

After weeks of waiting Samsung has finally provided the Source for the Q update. Is there anyway you can update the Kernel base for the Q source?

Thank you!

Yes, I've been requesting this since I got my SM-T290 in mid-October (when it went on sale for $89 at Costco) and Samsung finally posted it on Monday, along with the SM-T500. I'm actually building the custom kernel right now and should have an update for TWRP and a Nexus Stock custom ROM very soon.
UPDATE: Samsung seems to have changed the bootloader in Android 10 so that it won't support custom recovery even if the bootloader is unlocked and we substitute an empty vbmeta.img. This is another one of those Samsung VaultKeeper "features" that I find infuriating.
UGH!! I own both of these tablets (290 and 500) and just rooted the 500. I was hoping there would be some some custom ROMs coming out early next year for the 500.
Well, at least with the SM-T290 we can roll back to the Android 9 bootloader (minimally aboot and vaultkeeper), but that might not be an option with the SM-T500. We'll find out this weekend when I attempt to build TWRP for that newer tablet, which released with Android 10 and dynamic partitions.
The fact that you've been able to root the SM-T500 is promising, since Majisk modifies the recovery partition to do that.
Does this work with the Kids Edition of the SM-T290?
Really disappointed with this tablet, I figured since it only allows the user less than 32 gigs of space I could use an SD card in order for my daughter to download all the games she wants... only to find out there is no possible way to move any app to the SD whatsoever, actually the option to move apps to sd is not even greyed out it's just gone completely.
Doesn't seem to be many roms for the t290 available, and or if any roms out there could force that option back in.

My Nexus Stock custom ROMs do allow formatting the SD as internal so that you can store apps on it (although there are performance issues with SD vs. EMMC to consider). I've already got this working on Android 9, but was holding out for the Android 10 kernel source to be posted so that we can roll out on the latest OEM firmware. This issue with the Q bootloader is a setback, but I expect that we'll be able to work around it.
The Kid's edition is just a characteristic of the OEM firmware you install, and the hardware is identical, so you should be fine after you upgrade to T290XXU3BTI2. If you really want the Kid's Edition splash screen, I suspect that T290UEU3BTI3 will work with custom ROMs based on T290XXU3BTI2 just fine.

Oh ok thanks for breaking that down for me, I just was worried it wouldn't be compatible.
I would love to have a Nexus like experience on this thing, the more vanilla and pure Android, the better to me.
Would games on the sd card still play? Thats really my biggest reason as my daughter has already maxed out her space on it.
The last rooting/flashing I've done is from years back on an S3 and S5. I wish I could say my memory was good enough to feel confident about doing it.
So it would be unlock oem on developer mode, hook it up to a correct version of odin to put twrp in, then from twrp install magisk and also flash the rom right? I know I'm missing a ton of little details but just wanted to see what I could remember .
Thanks for your help
Quick Note: I just modified the Odin tarball to include legacy aboot and vaultkeeper images so that you can flash this custom recovery on Android 10 OEM firmware releases. The recovery image itself is unchanged.

Well, a custom ROM and rooting a ROM are two very different things. You can look at my Nexus Stock custom ROM for the 2019 Galaxy Tab A 10.1 (SM-T510) and see that it's very similar to Pixel Experience custom ROMs. Both are attempts to reproduce the "pure Nexus" experience, but with more modern Pixel boot animations, backgrounds, and Google apps.
Rooting can generally be done for any ROM now using Magisk to allow you to make changes, and there's a pretty good tutorial on that for the Galaxy Tab A7 here. My personal preference is not to root the system partition, but to simply make any changes using the TWRP File Manager where you already have root access.

Oh ok, i see.
Your Nexus rom for the SM-T510 looks awesome! Also, that Tab A7 tutorial is great.
On your original post, the first 2 downloads you have, the first one, "twrp-3.4.0-0-T290UES3ATC1-20201204.tar.md5 (Odin tarball)" that puts the custom recovery on the phone via ODIN. The second download, "twrp-3.4.0-0-T290UES3ATC1-20201101.img", is your Nexus Stock Rom for the T290, and is run from the TWRP recovery itself.
Does your T290 feel more responsive - less laggy with your Nexus rom?

Samsung doesn't do flashing via fastboot, so the .img file is really only for incremental updates via TWRP.

I think so, but I might be biased and I haven't had time to run any performance tests. I just posted the first release, though, so you can judge for yourself.
BTW, the $89 Costco deal is back until 12/27.
Quick question, I am having an issue using Smart Switch to make backups for my T500 on my Win10 machine. Seems like it just started and hangs up on applications. Any ideas? Want to install a few Magisk modules but want a back up first.

Wow and a free 32GB SD card. Awesome deal! I got mine for $99 from BestBuy with no card.
Would this work on the LTE variants (SM-T295)? I have one of those and I'm kinda tired of the performance issues plaguing One UI on that tablet. :/

I've been told that it does, but I haven't confirmed it myself because I don't have an SM-T295.
The links seem to be broken?

XDA Forum seems to have lost my last edit. Very strange, but I've tried to recreate it as best I could recall.

Okay, apparently the forum now forks a thread if you change the title. Bug or feature?
The new thread for TWRP v3.5.0 on the SM-T290 is here.
Any chance to get a working TWRP for latest stock firmware as of now?
