After @geiti94 and @ianmacd started the ball rolling for the Samsung Galaxy S10 series (Exynos 9820), it was really only a matter of time until we could do the same for the 2019 Galaxy Tab A 10.1 (Exynos 7904). The kernel source was released last May, allowing me to build a custom kernel with many of the problematic Knox security features disabled. What's posted below is a work in progress, but it should suffice to unblock efforts to build custom ROMs for this impressive tablet.
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 (T510XXU5CWA1).
This is unofficial and unsupported, so the usual caveats apply. Since we don't flash 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.

Good work. Well done.

Great stuff! I've received the device today, although I'm willing to test this recovery, it maybe better to wait a bit longer for a patched kernel/ROM instead? From my understanding this prevents the needs of booting in recovery every time to start the tablet and may be better to prevent Samsung/KNOX from bricking this device.
If this is untrue, please let me know and I'll remove this post asap.
Also let me know if you need any (debug) info.

NoKnox above will patch the T510XXU1ASC7 OEM firmware with the custom kernel and includes the vendor partition fixes in @ianmacd's Multi-disabler. Booting to recovery each time is only required with the Magisk root, which patches itself into recovery (TWRP or stock). More details on @ianmacd's post here.

Thanks for this! I successfully flashed NoKnox, TWRP and Magisk last night and all is working well! @PiCkLeS posted some helpful instructions here for those needing some extra help. Follow the instructions in this thread, but replace the last step with flashing your Magisk-patched TWRP image. No need to mess with running magisk on the stock AP file, you can just modify the TWRP recovery.img.

I just received the tablet and it's running T510XXU1ASCE, I suppose I should downgrade first, if possible, or will it work as-is?

Unfortunately, they've only posted the source for T510XXU1ASC7 at this point, so that's what we're stuck with. The safe bet is to downgrade (especially since NoKnox includes a modified vendor partition), but I wouldn't be surprised if you can mix and match these two versions.
Note: I see that the May 2019 update (T510XXU1ASCF) is already available. I've put in a request for the kernel source to be posted.

Thanks, downgrading from ASCE worked very well, had to change OEM unlock in dev settings again though (with the date trick).

@Magendanz, l'm willing to test twrp for the 515 model. Dm me ?

I did a backup and did a restore but it kept bootlooping idk if this was because i rooted it first or what..

They released the latest kernel

hello, thanks for your work, i'm building twrp for a device with the same soc [7904], i was wondering does disabling [proca] is a must to boot twrp ? if it's can you provide changes you have made to vendor partition to remove it
regards
edit: ok i see that you remove the init file for proca service [pa_daemon_teegris.rc] so my question now is, does using a custom kernel in boot image is a must ? i already use one in twrp with most of the security features such as defex/proca/samsung restrictions..etc disabled and if possible can you provide the used kernel source or used defconfig ?

I just manually perform everything that @ianmcd's multi-disabler script does to the vendor partition.

Yes, you've got to build a custom kernel to disable Samsung's rooting restriction features. The custom defconfig is here.

Been trying for a week now, still it bootloop at every attempt to enter twrp according to the testers.. not sure what's wrong, I'm building using twrp minimal source also custom kernel works good on stock rom so no idea where is the problem

Are there any release for SM-T515?

I have a volunteer to test it, but I was waiting for Samsung to post kernel source for the May 2019 update (T515XXU1ASEH).

'Only official released binaries are allowed to be flashed'
Thank you for this great work. I ended up getting the 'Only official released binaries are allowed to be flashed' at booting after flashing:
- NoKnox-T510XXU1ASEF.tar
- twrp-3.3.1-1-gta3xlwifi.tar
After the flash, the tablet successfully booted into new factory status OS. Once the intial setup was done and rebooted, the phone is just soft bricked with the message. Any idea what I've done wrong?
Thank you very much in advance.

That's Samsung's VaultKeeper "feature". To workaround it, you've got to connect to the Internet and enable Developer Options after setup.
So to recover, just flash the stock OEM firmware package with Odin, repeat the steps you took, and be sure this time to enable Developer Options and verify that OEM Unlocking is enabled. (It should also be grayed out, since the bootloader is already unlocked.)
And if you want to more permanently disabled VaultKeeper, I have a modified version of @ianmcd's multi-disabler script for the SM-T510 that you can install in TWRP.

Thank you!

Whoa, thank you so much for your quick and thorough reply!
I will do what you instructed after another 7 days I guess, (assuming there is no way to get around with this one).
Again I truly appreciate your contribution and hard work.

[Oreo][Stock][Rom] TWRP Flashable Stock Builds

About this project
This project provides repackaged Stock Oreo roms that can be flashed by TWRP. Modifications from stock are listed below.
As we are now moving into the Oreo world, I've decided that now is a good time to make a few changes to how things were done previously with Nougat. Please pay attention to the next few sections.
Modifications from stock
Note - It seems that I can't get DM-verity nor forced encryption disabled. The location of the fstab.qcom file is no longer in the Boot image. I found a similar file in the system image, but changing that appears to have had no effect. In order to disable these, use Magisk. UPDATE - Resolved since soak test 2, and soak test 1 with Aroma installer
DM-verity is disabled
Forced encryption of the data partition is disabled. It is still possible to encrypt the partition if you wish (optional with Aroma installer)
The partition table and boot loader are not included, which makes it safer to up/down-grade.
Do not attempt to apply standard OTAs over these builds. They'll probably fail, worst case they will brick your phone
Differences from previous Nougat builds
These roms are suitable for all channels. Previously there was separate firmware for different regions (e.g. retin had a separate build from retus), but as a general rule you are safe with any region's firmware.
I have now started using the Aroma installer for Oreo builds. Some of the below is now customisable at install time. Aroma installer zips will have "-aroma" in their filename.
The modified boot logo will no longer be included in the rom download. A separate zip will be provided to just flash the modified logo.
EFS will be erased on install! If your persist is intact, EFS will recreate itself. With the amount of exposure that the lost IMEI issue has had, all should be very familiar with the importance of backing up persist and EFS. And those that have had a compromised persist, will know that they should be hanging on to their EFS backups for dear life. Full details of the issue and solution (for those with intact persist) is here: Fix Persist, resolve IMEI=0, Volte, 4G, Explanation, Requirements From my perspective, the EFS is erased installing OTAs for a reason. I don't know what it is myself, but the folks at Motorola build it into their OTAs and they know far better than I do.
As a mitigation to the risk of people forgetting/losing their EFS and / or Persist backups, I will have a very crude backup system integrated into the zips. However, it will take some skill / knowledge to restore from these backups, and they should not be relied upon over the long term. Refer to the second post for more details.
Important information if downgrading to Nougat and Custom Oreo roms
The Oreo roms will change the ownership of specific files and folders in the /persist folder. As a result of this, stock Nougat will have issues such as lost IMEI, no Volte, no 4G, etc. In order to overcome these issues, either follow the instructions in the link above, or flash the following zip in TWRP.
potter-stock-persist-fix.zip
Additionally, the latest Nougat builds with the Aroma installer will apply the persist fix when installed.
Another potential issue is that, as a result of various partitions being updated, the new Oreo blobs may not be compatible with existing Nougat roms (stock or custom), or even current Custom Oreo roms. This may result in issues such as the fingerprint reader not working, etc.
UPDATE: Some custom roms are now using the Oreo blobs. However, if you require the older Nougat blobs, you can downgrade through one of the following methods:
1) install one of the latest Stock Nougat TWRP flashables. This will ensure that all affected partitions are compatible with Stock Nougat and Custom Oreo roms. You can get these from this thread here:
[Nougat][Stock][Rom] TWRP Flashable Stock Builds
2) install one of the firmware-only zips from the below folders. Note that if this results in other odd behaviour, you may need to install and boot into a full stock Nougat firmware as above. The main benefit of these zips is that they are much smaller, ~50MB rather than ~1.4GB.
https://www.androidfilehost.com/?w=files&flid=273039
potter-firmware-92-14.zip is for retin, retla, retbr
potter-firmware-93-14.zip is for retus, retapac, reteu
Out of respect for the purpose of this thread, please keep questions about whether or not to use Nougat or Oreo firmware for particular custom ROMs in the thread for the custom ROM you are trying to use. I do not support other custom ROMs - the maintainers of those custom ROMs should provide guidance.
Usage
Steps to flash
Ensure you have the latest TWRP
Download an appropriate zip from one of the links below
Copy to the phone or SD card
BACKUP YOUR DATA, INCLUDING EFS AND PERSIST
Flash the zip via TWRP
Optionally flash Magisk etc - NOTE - in order to disable dm-verity and forced encryption you must flash magisk before rebooting Resolved since Soak Test 2 and Soak Test 1 Aroma installer, Magisk is optional
Reboot
Profit?
How you can help with new builds
If your phone gets an OTA notification for a build that has not been released, please pull it and share it in this thread:
When the notification is received, allow your phone to download the OTA
Power off and boot into recovery
Go to Advanced -> File Manager
Navigate to /cache
There will be a file Blur_Version_x.y.z.potter.blah.zip - Note - Oreo OTAs may not be named this way, they may be named according to the version of the rom that is currently installed
Copy it to internal storage or the sdcard
Copy to PC (optional)
Upload to Mega, Google Drive, wherever
Share the link
You can also remove the file from the /cache folder to prevent any auto-updates from happening.
Latest versions
The 85-13 series is released to most channels except retus, and the last update was to 85-17-2.
The 85-17 series is released to the retus channel.
However, all releases can be used with all channels.

FAQs
Frequently Asked Questions
What is the 'very crude backup system integrated into the zips'?
This is a script that is run at the start of the install. It's purpose is very simple - it creates "dd backups" (i.e. bit-perfect images) of the modemst1/2 and persist partitions. They are stored in your sdcard as "backup_yyyymmddHHMMSS_modemst1.img", etc., where yyyymmddHHMMSS represents the date and time the script was run.
For this to work, your data partition must be mounted. I haven't included any checks for this (I'm not really a shell script person - it would take me hours to get this sort of thing right) - this is what puts the "crude" in "very crude backup system". UPDATE - the aroma installers now check that data is mounted, and abort the install if not. Most of the time the data partition will be mounted in TWRP, so this will work 99% of the time. Caution should still be applied, and you should still copy these or any other backups to cloud storage to be safe.
OK, so if I needed to use these backups, how do I restore them?
To restore these, you will have to reboot into TWRP and open up a shell or use adb. The commands to restore each partition are as follows (replacing yyyymmddHHMMSS with the appropriate values of course):
Code:
dd if=/sdcard/backup_yyyymmddHHMMSS_modemst1.img of=/dev/block/bootdevice/by-name/modemst1
dd if=/sdcard/backup_yyyymmddHHMMSS_modemst2.img of=/dev/block/bootdevice/by-name/modemst2
dd if=/sdcard/backup_yyyymmddHHMMSS_persist.img of=/dev/block/bootdevice/by-name/persist
Note that these commands are very powerful, and applied incorrectly can result in you bricking your phone if you overwrite the wrong partition.
So are dm-verity and forced encryption now not able to be disabled?
OK some history... Nougat had fstab (file system table) in the boot image. So in those days, I would open up the image, and edit the fstab.qcom file, do the appropriate changes, repack the boot image, and all is fine.
Now, under Oreo, the fstab file is not in the boot image, it's under /system/vendor/etc/fstab.qcom or similar. Editing that file appears to have no effect. For now, Magisk is the easiest way of disabling both, but you must make sure to install it immediately after installing the rom and before rebooting.
Update - this is now resolved in the second Oreo soak test download. dm-verity is still disabled in the boot image, but a completely different way. Once this is done, disabling forced encryption works as expected.
Which partitions are modified?
The short of it is this - boot, system and 'firmware'-related partitions. None of the bootloader partitions are updated. The full list of partitions that are written is:
modem
fsg
dsp
boot
system
oem
Note that this list applies to the Nougat and Oreo flashable zips.
TWRP is no longer installed after flashing this
I believe this is related to dm-verity (see above). You will have to first reinstall TWRP via fastboot. When TWRP is back, install magisk immediately after installing the rom, and before rebooting.
I'm having problems with an Oreo custom rom after installing this rom, what can I do?
Refer to the OP, the section about downgrading to Nougat - the same approach applies. Oreo Custom roms will have been based upon the available Nougat blobs that were available. As the blobs have been updated in the Oreo release, the issue is that they are not compatible. So install a full TWRP Nougat zip and then install your Oreo Custom rom.
Dirty or clean flash?
I did a dirty flash, as I came from the latest Nougat stock rom. Keep in mind that this is nothing more than the OTA applied to the previous Nougat build and packaged into a TWRP zip. So, as long as you have come from (the latest) Stock Nougat, you should be able to dirty flash, as that would be the use-case for the OTA. If you were on another rom, clean flash required.
Once you are on one of these builds, you can dirty flash subsequent builds. Again, this would be just like flashing one OTA after the other. Also note that these builds are complete in their own right, you don't need to incrementally flash - you can flash the latest to get the full install.
My device was encrypted, and I really need to decrypt it. How can I do this?
Sorry, but the only way is to format the data partition. That means you will need to backup your data, and your internal storage as well (/sdcard). After backing up, use TWRP to format the partition. From the TWRP main menu, select Wipe > Format Data. Then follow the on-screen instructions.
Is it 32 bit or 64 bit
32 bit. We've known this would be the case for a long time.
How can I create flashable zips myself?
I created the guide below, and it has been updated for Oreo. A word of warning, it is not for the faint of heart. You will need to have a good understanding of the Linux command line, and be able to understand the techniques that are being taught, rather than expecting that the process is a 'step-by-step'. Adaptability is key here.
[GUIDE] Creating TWRP Flashbale Stock roms
What are the new Aroma zips?
The aroma zips use the Aroma installer. Some of you may have seen the Aroma installer for Open Gapps. The key here is that I, as the packager, can build in selection options into the installer. It's all available as a nice GUI for the users to pick and choose from the options I've provided. Here are the options that are available:
Do backups - does the backups as mentioned earlier in the FAQs.
Erase EFS - erases modemst1 and modemst2, as described in the first post. Also DDR is erased, but I'm not sure what purpose that has but it may as well go together with these.
Install Firmware - installs the following partitions - modem, fsg, dsp; each of these has something to do with hardware / connectivity.
Install System - Installs the following partitions - boot, system, oem.
Apply patches - as long as Install System is selected, will install the patched boot image with dm-verity disabled, and will edit the fstab (filesystem table) to disable forced encryption.
On soak test 2 or later, I have my IMEI but no signal. What can I do?
In all cases where this has happened, the user's phone has relied upon an EFS backup for IMEI, due to flashing another persist. In these cases, it appears that the only way to get a signal is to use the firmware (i.e. modem, fsg, dsp - refer previous FAQ) from soak test 1. We're probably seeing here that the EFS does in fact need to be recreated to be valid. Unfortunately for these users, by not having their own persist, they are stuck with an old EFS and the newer firmwares appear to not work.
To do this
if you are already on Soak Test 2 or later, download the Soak Test 1 firmware download at either of these links:
Android File Host - oreo-soak1-firmware.zip
Dropbox - oreo-soak1-firmware.zip
If you are on Soak Test 1, install Soak Test 2 or later / official aroma installer and de-select firmware
My fingerprint is not working on my custom ROM
Refer to the thread for your custom ROM, and ask questions there. In short, Nougat and Oreo firmware are not compatible with each other. Many custom ROMs are now using Oreo firmware, whereas previously (before October 2018) pretty much all custom ROMs were using Nougat firmware. It's messy now, but please ask the questions in the right place (which is NOT this thread).
My touchscreen isn't working after flashing, even within TWRP
This seems to happen somewhat rarely, although I don't know what the cause is. As it affects TWRP as well, and TWRP uses the 'modem' partition for getting its firmware blobs, I guess it's possible that this particular partition is getting a conflicting modification whilst flashing, which is causing problems (but this is purely speculation on my part).
To solve, fastboot flashing the stock ROM appears to work. It may also be possible whilst in TWRP to manually flash the partitions via ADB, but that takes a bit of work and knowledge. Until someone can truly work out what's happening and the minimum required to fix it, stick with fastboot.
Update - refer to post #3 for the latest information about this issue.

Touch screen unresponsive even in TWRP
The below post has the latest information on the Touch Screen Unresponsive issue
Likely Cause
From the testing that I've done to reproduce the issue, as far as I can tell the issue is that Stock Oreo is not able to be safely applied over the top of old builds of Stock Nougat. Furthermore, it doesn't seem to matter if you were on Custom ROMs after you were last on Stock Nougat, just what Stock Nougat build you were on last.
Avoiding the Issue
Again the key here is what build of Stock you were on last (and I guess booted into). So, if you were never on Stock Oreo, and you aren't sure what version of Stock Nougat you were on last, then the safest path to getting these builds working is to first flash the latest Nougat Stock ROM.
Get the latest from this thread: [Nougat][Stock][Rom] TWRP Flashable Stock Builds
Once you have flashed the latest Nougat, boot once to make sure everything is working. After that, you should be able to safely upgrade to Oreo.
Fixing the Issue
If you have been affected by the issue, most people have been able to get back the touch screen functionality by flashing a fastboot version of the ROM. However, as long as you have a PC handy you will be able to flash using TWRP as well via adb, using the steps detailed below. A third option is to connect a USB Mouse via an USB OTG adapter.
Note that for either method via TWRP, you cannot use the versions of the ROM with the Aroma installer, as the mouse is not supported within, and there is no way of providing input by adb.
Downloads
The 92-14 or 93-14 versions should be suitable. They are in these links (these do not erase EFS, so for the paranoid, you will retain your IMEI):

adb push twrp-flashable-potter-NPNS25.137-92-14-no-erase-modemst.zip /sdcard/
If you want to backup, you can do this via the command line as well. I haven't tested this myself, but the commands are available here: https://www.pocketables.com/2014/10/using-twrps-new-adb-interface.html
The example provided uses the following to back up system, data and boot, and compress:
Code:
adb shell twrp backup SDBOM
You will need to do a clean flash, so these commands will wipe data / factory reset and then install
Code:
adb shell
twrp wipe data
twrp install /sdcard/twrp-flashable-potter-NPNS25.137-92-14-no-erase-modemst.zip
reboot
After the reboot, you should have your touch screen functionality back. Then reboot to recovery, and install Oreo as normal. If for any reason the Oreo flash doesn't work, try the steps again, but rather than installing the latest Oreo, install an earlier one.

Awesome bro...
You Rock...
you even included auto backup of efs and persist ... wow thats very thoughtfull and nice of you...
hatsoff..
:good::good:

Thanks for uploading. Two questions though...
1. which one would be suitable for retin? (India)
2. Are there any bugs?

working for retin also thnx

Question: I'd like to flash this, but I'm planning to roll back in the future to take the OTA back up to O. If I restore nougat system, boot, persist, recovery, oem will that still be possible? I see some other stuff in the zip like adspo.bin, fsg.mbn, and modem. Not sure if those it lead to OTA failures or a brick.
also, nice job on the persist/efs script!

Worked on retin also thanks. Great work!!!!

I'm pretty sure forced encryption of the data partition is still enabled.

If that's the case magisk is probably needed to turn it off. Sorry, but I've only tested it with magisk installed. Moto have changed the fstab location, I thought I got it but maybe it's cosmetic and doesn't do anything. Will update OP when I get a chance.

Yes, when you do;
rom installation > format data > flash magisk
everything is okay
verified.

Did Moto make Oreo 64bit?

Good question, and this is something that I needed to consider before doing this, in case everyone installed this and we'd have no path to get to official Oreo.
Refer to the section in the OP "Important information if downgrading to Nougat". Basically you need to follow all of that to be able to get notification of the OTAs. Once the official public Oreo OTA is available, I will then put together a zip based upon the pre-requisite nougat rom with the official Oreo OTA.
I also believe that one or both of the 1 July 2018 and/or 1 August 2018 patches were announced, but neither were for Oreo. I do intend to keep Nougat up to date as well in its thread.

I've only just added something to the FAQ (post 2) that covers this. Sorry, it was unexpected and didn't come up when I was testing as I always had magisk installed. Follow these steps:
TWRP is no longer installed after flashing this
I believe this is related to dm-verity (see above). You will have to first reinstall TWRP via fastboot. When TWRP is back, install magisk immediately after installing the rom, and before rebooting.

Maybe I'll try tweaking the zip to see if we can run it without the stuff we can't easily backup/restore with twrp. I'll take a stab at it shortly and let you know what happens if we flash just system, boot, and OEM.

You can give it a go, but I've already done some very brief testing. Using the Nougat modem partition on the Oreo system results in things like 3G only, fingerprint not working.

I'm guessing you don't have root either? If you did, you could try installing it from a shell from within the rom:

In the spirit of moving custom ROM development along for the 2019 Galaxy Tab A 10.1 [SM-T510], here's a build of LineageOS 18.1 I just created based on the latest OEM stock firmware and @AndyYan's latest LineageOS 18.1 GSI. It's very much a work in progress, but it should hopefully help blaze the trail for even more custom ROMs for this tablet.
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 this one is based on the latest Android 11 release (T510XXU5CVG2).
Stock recovery will be replaced with my latest TWRP build for the SM-T510.
This is unofficial and unsupported, so the usual caveats apply. Since we don't flash the bootloader, you should be able recover from any problems...but nothing is guaranteed.
Not working:
Support for file-based encryption

When I try to installing gapps in twrp, twrp crashes and reboots. Using open gapps arm pico. Is there a way to install google apps on this rom?

Yes, I've noticed that myself, and it seems to occur when writing to certain modified vendor partitions. Anyone have an idea of what might cause that?

Hiya
Just got this device today.. pretty stoked to get it rooted & Lineage going.. thanks for your projects & info
I'm curious do I need to change any of the Options tab in Odin ?
Auto Reboot off for example ?
Auto Reboot & F. Reset Time are checked by default none of the others are.
At this point in this device's progress assuming I unlocked correctly & get into Download mode.. flash with Odin successfully I should just Auto Reboot right into TWRP & can go from there ?
NoKnox is a thing of the past ?
What about Multi-disabler ?
If I install Magisk & plan to how do I ensure I don't "boot outside Magisk" I keep hearing people say.. where Vaultkeeper & similar things may become problematic or so I've read.
Someone did offer some advice on not booting outside Magisk a few weeks ago I'm going to go find their message too but yeah I've read a lot of threads here & it seems like since certain packages & older methods like patching TWRP with Magisk are things of the past.. I just want to confirm what all else is
is charging past 80% an issue at all with this ROM ?
That's one thing I see people mention about custom kernels is they fix that.. well that & EX or Franco would be rad if they exist for this device & rom

I don't use Magisk, and so I'm really not the person to ask. Note, however, that custom kernels in boot and recovery partitions are slightly different wrt MTP. Boot kernel uses Google MTP and recovery one uses Samsung MTP to maintain compatibility with OEM system if patched with Magisk.

Thanks for sharing this and great job! Got it up and running smoothly with gapps and magisk pretty easily.
Haven't noticed any major issues other than that my SD card can't be read. It keeps showing the notification "Issue with SD Card - Tap to fix". I'm able to format the card successfully but the error returns the sd card isn't readable. Tried it with two different brands and getting the same issue.

I'm confused by your terminology. The bootloader is locked or unlocked. Developer mode and OEM are enabled or disabled. I'm assuming you are referering to OEM but I'm not certain. Normally when coming from stock, you enable Developer and OEM and then unlock the bootloader. That will also cause a "factory reset". You then need to reboot and once again enable Developer mode. OEM will normally still be enabled and grayed out. Then you can start the Odin flashing. Also, you shouldn't let it do the OTA because the TWRP needs to match SK1.
edit: The original instruction are a little confusing. They tell you that after each step you have to boot and enable Dev mode in order to chech OEM enable. The real reason is that you have to enable Dev mode in order to flash anything but stock. Without it enabled, you get the message in red saying that only original firmware can be installed.

I already successfully installed lineage. I was doing it for a business who needs to have the tablet rooted, but the program they needed was finiky with the custom rom, so I tried to go back to factory.
Where I think I messed up is I flashed all the BL, AP, and CSC, from the stock firmware. how ever I wanted to throw lineage on to test and now when I try to flash lineage again it gives me an error on the tablet.
Error : "only official released binaries are allowed to be flashed(BOOT)"
and the flash stalls out on odin.
So i checked to see if it was boot unlocked still it was. so I reverted to sk1 (my tablet was bought from the store yesterday with sk5) and I let the tablet OTA update, and tried the process again to no avail.

Maybe so. But it isn't officialy supported, so if it doesn't work, it doesn't work. I tried it with several apps on several ROMs and could only get it work on my T580 by reverting to an Android 8. Every thing I tried in Pie either froze or caused the tablet to reboot.

You triggered Samsung's VaultKeeper "feature" when you rolled back to the OEM firmware. In order to prevent that, you need to immediately enable Developer Options while connected to the Internet after setup (before rebooting). If you don't, VaultKeeper places the device in a hybrid state where it looks like the bootloader is still unlocked, but it still won't allow Odin to flash firmware unless it's signed with Samsung's release keys.
Flashing a known-good OEM firmware should remedy the problem, provided you verify that the OEM Unlocking setting is enabled in Developer Options and go back for a Volume Up long press from the blue warning screen to complete the bootloader unlock. Did you do that after booting while holding the Volume Up & Down with the USB cable attached?

Do you know why is still not possible to decrypt pie? And why you do not recommended to disable it? At the beginning everyone wanted disable this.

1. it is no possible to decrypt stock pie due to HTC proprietary encryption protocol, it is not Open Source, and the Dev that made it possible @nkk71 to decrypt previous HTC Encrypted devices passed away, and no one has been able to take over his amazing work.
2. It is not secure to have an un-encrypted device, at the end is your device and your choice,

Hello, installed following the guide and got this

I also have a problem with this recovery. I want to make a nandroid backup ( system , boot and data ) i am on viper rom gsi now. I always have this error when i launch a backup , : unable to find partition for path '/system. In mount the system is checked and the mount system partition read only is not possible to uncheck it.
After that i have try the twrp updated for viper rom and is working fine this one no problem for backup.

new version uploaded, it should be as stable as official TWRP + some extras , & now become almost official release, still a pre-official test for official release

Got it! , I will try it! Can you tell me if you flash permanent the recovery you still can flash a ruu later without do anything else? Also on the viper rom you suggest to flash your Touchscreen hexpatcher ? with flashing the header patch from venom or only the kernel pie 0.2 from venom i am not sure with what i have read..
Thanks you!

RUU should always works if done properly regardless of whatever you flash in your phone, and the hexpatcher will be only needed if you are on stock kernel, if you are using a custom kernel, then use the patch from venom

I have asking it for to be sure, because some of my old phones like the htc 10 when you flashing a bootloader without a red text you should restore the original bootloader for flashing a ruu or a firmware if i am remember correctly.. I am pretty sure you are already know that but is for why i have asking it.
For my other question , so i am assuming the viper is on a custom kernel so i know now what files flashing.

Rom and kernel are 2 different things, you can flash viper Rom and have stock kernel, or you can flash a custom kernel, custom kernel do no need the hexpatcher only stock kernel does regardless of the Rom you are using

Of course i know rom and kernel is a different things. I was thinking since the viper is not a official rom is need a custom kernel.

it doesn't requires a custom kernel, it is completely optional, just remember, if you stay on stock kernel, then you will need hexpatcher, if you use custom, as far as i know there are 3 available, CleanSlate, Kirisakura, & Beyond Stock, any of those 3 you will no need to use the hexpatcher

I have forget to tell you since your recovery is a port from twrp, when I write you about the bugs the other days, after that I have take the last twrp I have make a full backup with no errors , more later I have restored my backup with... I had got a bootloop on htc logo every times, I have trying to fix it but nothing to do... I was forced to install again the viper rom after that I was able to restore the data partition and is worked. Probably a bug in twrp restored, I am guessing probably have this bug on your recovery also.

@JEANRIVERA, thanks for the great job and maintaining TWRP!
I assume, it is still not possible to do a data backup on Pie (without this one)?

Not possible, this recovery is based on TWRP, every limitations on TWRP will also be here, Devoting HTC stock Pie at the moment is not supported by TWRP, but you can Decrypt AOSP Pie Encryption for example GSI ROMS based on PHH work like ViperExperience,

@JEANRIVERA I have done what you said and i have a problem , I have flash your recovery after that i have flash your touch patch and magisk.. reboot.. Android work fine.. ( except I was forced to delete some files in the recovery about the lockscreen , he didn't want let me to put again my password.. ) after that i has put again my password.. )
The problem now is on the recovery i boot it from the bootloader, the recovery stays on the logo pitch for a long time after that is said to me to put my password i enter it but it never want to decrypt the data. So i do not know why the recovery do not want the decrypt the data and why is stay so long on pitch logo every times. I have not flashing viper patch because is for custom kernel.

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

I'll have a release of my Nexus Stock custom ROM shortly. It's basically the same as what I've been releasing for the 10.1" version of this tablet over the past year. I'm basically just waiting for Samsung to post the latest kernel source.

I have tried installing via Odin your twrp custom recovery for my t290 device.
The process with Odin seem to go well and after installation my device restarts however, when I press the + volume button, android recovery shows up and not TWRP.
Any idea why?

There are two issues here:
The process of entering recovery on the SM-T290 using buttons is really finicky, unlike the 10.1" version. My best result has been with holding Power + Vol Up on startup, quickly switching to hit Power to dismiss the bootloader unlock warning page, and then immediately holding Power + Vol Up again for 6 seconds. (Holding longer will cause a hard reset.)
If you miss on the first attempt and haven't installed Multidisabler, it will revert your custom recovery to the stock OEM recovery.
So, try your best to get it right the first time, and don't be surprised if you end up with stock recovery if you mess up.

Presumably, if you miss the first time, you reflash and try again? (and as many times as needed?)

If you miss, hold Power + Vol Down for 7 seconds during the boot animation to do a hard reset and try again. Alternatively, you can wait for it to finish booting and then restart, but then you risk Samsung's VaultKeeper "feature" putting the bootloader into a stealth locked state. You can prevent that by connecting to the Internet, enabling Developer Options, and then confirming the OEM Unlocking state as soon as you finish setup. (You don't need to log into Google or Samsung services for Vaultkeeper to maintain the bootloader unlock, but you've got to have Internet access and reenable Developer Options right away.)

Thanks for pointing out some of the potential potholes along the way. I'm not a stranger to modding, but have experience only with fastboot, so the Samsung method is a whole new ballgame for me. Maybe I just need to take a deep breath and jump in. And backup everything before starting.

Yeah, it never ceases to amaze me how Samsung believes it's adding value with Knox security features like Vaultkeeper and its special Download mode that only works with Odin. My main phone is a Pixel 4a, and I've never felt that Google has taken any flak for making bootloader unlocking and firmware flashing painless. Why does Samsung feel the need to reinvent the wheel?

Somewhat to my surprise, I was able to get TWRP installed and boot into it on the first try. In fact, the biggest difficulty by far was getting Samsung drivers to work in my Windows 10 vm. The vm is still having problems, so hopefully, now that TWRP is installed, I won't need to use Odin for a while.

Tried patching TWRP with Magisk. No bootloops or other drama, but wifi doesn't work. I notice on the Magisk Github site that a number of people are running into this. Fortunately, restoring the unpatched TWRP also restored wifi.
I think I can live without root much more easily than without wifi!

I have root and wifi, but didn't use the TWRP install method

Further to this post about the inability to set a password, PIN or pattern:
I reflashed the stock ROM and I can verify the following:-
Stock ROM with (or without) bootloader unlocked will allow me to set up a PIN (I didn't try the other options but would expect that they'd work.
As soon as I install TWRP, the stock ROM will no longer allow me to set up a PIN. I can have "swipe" or "nothing" to unlock, and that's it.
I've tried installing LineageOS 17 GSI, LineageOS 18 GSI and Magendanz's Nexus stock ROM. None of these will accept a PIN, password or pattern.
Therefore, I think that the issue has to do with TWRP, or possibly with something in the multidisabler script.
Googling has come up with nothing other than the instruction to remove /data/system/locksettings.db and related files. I've tried this numerous times without success. I've even tried comparing permissions and ownership with the (working) equivalent on my Moto phones, with no luck.
I'm happy to do any tests, provide logs etc if it would help. The only other alternative seems to be to revert to stock if I need to travel.

I'm going to be using the table in an install that does not allow easy access to be able to use the physical buttons, if I lock the boot loader back after all this will it keep root?
I need root so that I can modify the files necessary to make the tablet turn on automatically whenever power is connected.

Do we need to update the underlying stock ROM first if TWRP is already installed? Or is it sufficient to flash TWRP from the existing TWRP?

You can just flash the new .img file from an existing TWRP install. The version of the kernel is only important if you're using Magisk (which boots through the recovery partition).

Thanks. That was easy. As far as I can tell at this point, it all works.

[ROM][SM-T510][UNOFFICIAL] LineageOS 19.1 for Galaxy Tab A 10.1 (2019)

Thank you dear @Magendanz very much for keeping my Old Youtube Tab Alive!
Quick Question, is an update from "lineage-18.1-20220417-UNOFFICIAL-T510XXU5CVB1.zip" to the new 19.1 Possible or do i have to update the base version first?

Good evening Mr. Magendanz,
i installed this ROM on my Samsung SM-T510 and my tab/back/home buttons are not in the middle/bottom position they are in the right corner (i had this issue also with another unffocial lineage Os 19.1 Rom for SM-T510)
How can i solve this ?

Is the task bare active? I have the same layout when it is. You can turn it off in settings, but research the bar, you might want to use it.

@Magendanz , I dirty installed it over my lineageos gsi, and it works great so far. One problem I see, and had with the gsi is that I have a notification to finish installation, but there is no way to get past the network selection. There is no button to either skip or continue. Is there a way to fix this?
Thank you for this - I know how hard it is given your other responsibilities!

Thanks Magendanz for this news!
Coming from LineageOS 17.1 (lineage-17.1-20200812-UNOFFICIAL-T510XXU3BTFN), what would be the sequence of steps for updating to this rom ?

I recommend you download and install the T510XXU5CVG2 firmware, do a clean install with Odin...but intercept the restart by holding Vol Up & Down so that you reenter Download mode. Then, install this custom ROM with Odin and intercept the restart by holding Power + Vol Up to enter TWRP. From there, do a factory reset and reboot to system.
If you inadvertently miss the restart intercept and have to run through OEM setup, make sure to connect to the Internet and then enter Developer options to disarm Vaultkeeper. Don't try to flash anything else until you've verified the OEM Unlock is still on (but disabled).

Thanks Magendanz for this clarifying tutorial!
So you must first always update \ have the samsung base AND the custom recovery to a MINIMUM combination set? In this case the minimum "combo" set would be a samsung rom with android 11 as base (and recovery 3.6) right ?
Will try this sequence and give feedback as soon as possible.
Thanks again.

Hey there, just wondering -- does hardware video acceleration work on this build seeing as its based on a GSI? Thanks

I tried to flash this on T515 via twrp. Seems like it only detect and allow install on t510

In the ten or so years I've been dealing with Samsung tablets and XDA, I must have seen this question asked at least a hundred times. "Can you make the wifi ROM work on the LTE version?" of whatever tablet or vice versa. And the answer is always "No." They are two different animals and normally the dev has one or the other. And it is very difficult to make a ROM for a device you don't have. And the same thing goes for tablets with the S Pen. They are NOT the same.

of course mate i like your passion in explaining such things but i belive *i can be wrong of course* that i wasn't asking on a Xiaomi Poco thread..... this two devices are very much similar, smt510 twrp works correcly on smt515 for example. Just maybe the rom could also work with some little tweaks. Thanks

Yes, TWRP can work on both but recovery doesn't access the LTE modem. And, again, I'm stating MY experience from over ten years of having people ask the question about many, many SAMSUNG tablets only.

Has anyone successfully installed MindTheGApps on lineageos19? did you use an sdcard or adb or some other method? I don't have access to an sdcard but I am curious if this is the only way. I have not been successful in using adb..... yet!

This version of Lineage 19 already has Gapps installed. So MindtheGapps is not needed. Installing it using the tar ball and Odin means you don't need an SD card. Or have I missed something?
