[ROM][SM-T510][UNOFFICIAL] LineageOS 18.1 for Galaxy Tab A 10.1 (2019)

[Magendanz]

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

Downloads:

• lineage-18.1-20220907-UNOFFICIAL-T510XXU5CVG2.tar.md5 (Odin tarball)

Does the ethernet-function (LAN) work?

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


/salute

Nope.

Yep.

You still need to run Multi-disabler if you're installing TWRP, but it's baked into this custom ROM.

is charging past 80% an issue at all with this ROM ?

No longer an issue with this custom kernel.

If I install Magisk...

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.

OpenGapps won't work. I tried and a few and managed to get it working with BiTGApps for Android 10. You can get it here:

I successfully installed lineage, but then I had to go back to stock. now when I try to install it again, I am only getting a error; "only official released binaries are allowed to be flashed(BOOT)"

I cannot get back into lineage any advice?

I used odin and flased the BL AP and CSC nothing is changing, wont even let me install twrp any more

Did you re-enable Developer mode and OEM?

it was never locked again to being with. the option was greyed out saying it was already unlocked. but I did relock it then unlock it. no avail. is there a timer or something with these tablets if you mess up?

I even downgraded to sk1 and then let it do a OTA update while locked

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.

Did you read my "edit" where I said that was caused by not having enable Developer mode?

I did not see your edit, thank you I will try and inform the community.

Miracast is no longer supported in Android 9 or 10. It isn't just this ROM. Chromecast is still supported but not miracast.

my mi a1 with stock pie and the t510 stock rom still can use it

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?

No luck for me with this, TWRP still reboots when trying to install gapps/bitgapps . I'm not sure what else to try.
