[ROM][9.0][UNOFFICIAL] Nexus Stock for 2019 Galaxy Tab A 10.1 [SM-T510]

[Magendanz]

In the spirit of moving custom ROM development along for the 2019 Galaxy Tab A 10.1 [SM-T510/T515], here's one I just created based on the September 2019 Update and @AndyYan's LineageOS 16.0 GSI. It's very much a work in progress, but it should hopefully help blaze the trail for even better work.

Notes:

• The current process may require 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 November 2019 Update (T510XXS3ATB4) for the SM-T510.
• The system is based on @AndyYan's LineageOS 16.0 GSI with the latest Stock variant from OpenGApps.
• Boot logo and default wallpaper is from my Nexus series of custom ROMs for Android TV, and I'm using the Pixel boot animation with black background.
• Stock recovery will be replaced with my latest TWRP build for the SM-T510.
• I've dialed back most of scary bootloader warnings and Knox Security branding from the boot sequence.
• 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

Oo our first custom rom!! Thanks alot!! Cant wair to try it soon

 

[Magendanz]

Important Note: The Night Mode setting in Developer Options is set to "Always off" by default. Don't change it! When I set it to "Automatic (based on time of day)", the screen went black and I couldn't recover without a factory reset. (I'm assuming that this was a bug in SystemUI.apk.)

 

[NightHawkUndead]

Thanks for the effort and time you've put into this.
Unfortunately I can't get it to work. I will wait for detailed full instructions. I just keep getting Odin fails.

Well, I just verified the MD5s and they match. However, to be a little more squared away, I replaced the original .tar file that I uploaded with a .tar.md5 (a.k.a. "tarball) which has the MD5 footer that Odin can use to verify the file integrity. I've also compressed the contents with LZ4, which cut the size down by a third.

Installing the new tarball with Odin3 v3.13.3 on my tablet went smoothly, so I hope this works for you.

 

[NightHawkUndead]

Finally got it to work. Had to flash back to stock. Wipe. Then immediately reboot bootloader again and flash Rom.
How do I go about rooting now?

Edit: nevermind, got it rooted. Everything is working fine now!

Sent you a donation for your work. ? ?

I have a new SM-T510 on T510XXU1ASEF

I flashed this ROM with Oding3 3.13.3. Then it rebooted. The Nexus logo goes by, I am asked to confirm the ROM is non-standard by pressing the "power" button. Then I get the TWRP splash screen, and it hangs.

Tried to flash 3 times, same result.

Is there something to going back to stock, wiping, bootloader, flash again? Or is that just doing things until it works?

It's important that you wipe the data partition before TWRP boots, since it currently hangs when it encounters an encrypted file system. (Yes, this really shouldn't happen, but I haven't found a fix for that TWRP bug yet.)

Did you select "Wipe data/factory reset" in the stock OEM recovery immediately before you flashed this custom ROM?

 

[garyemiller]

"Did you select "Wipe data/factory reset" in the stock OEM recovery immediately before you flashed this custom ROM? "

Yes.

I got it to work. reinstalled stock rom (link above). Booted it stock. Enabled Developer Mode, Enabled USB debugging. confirmed OEM still unlocked. Boot to recovery, wipe, boot to bootloader. Flash this ROM with Odin3. reboot. All is well.

So now I guess I gotta do the Device ID dance. Install Magisk Manager, patch the boot.img from your tar file, then use TWRP to install the magisk_patched.img as boot.

Along the way I also wasted a lot of time trying to flash with heimdall 1.4.2. But that was very flakey. Odin3 just worked.

I guess I should mention my biggest issue was unlocking the bootloader. Not like before.

Power off. Hold Vol UP and Vol Down. Plug in USB. Long press Vol UP to unlock.

So now I guess I gotta do the Device ID dance. Install Magisk Manager, patch the boot.img from your tar file, then use TWRP to install the magisk_patched.img as boot.

If you install Magisk, you might not have to do the device certification dance. It tries to fake out Play Protect.

 

[garyemiller]

The device certification was painless. I've doe that before on other devices.

Rooting with Magisk was also painless:
Grab boot.img from your tarball.
adb push boot.img /storeage/emulated/0/Download
patch using Magisk Manager
adb pull /storage/emulated/0/Download/magisk_patched.img .
heimdall flash --BOOT magisk_patched.img

I can't get SafetyNet to pass, even with Magisk SafetyPatch module. But not a big deal to me.

Is there a way to turn off the google page on the launcher?

Thanks for the nice ROM! So much better than stock.

I'm still looking for a good ad blocker for Pie. Up tile now I have used a Raspberry Pi as a dnsmasq server for ad blocking.

 

[Magendanz]

Is there a way to turn off the google page on the launcher?

If you open up the Android One Launcher settings, there's a "Display Google app" option that you can disable.

I can't get SafetyNet to pass, even with Magisk SafetyPatch module..

Yeah, I've tried the usual tricks like spoofing the fingerprint, but that didn't work either. This kind of hard Play Protect device rejection seems to happen for me whenever the vendor partition is using release keys and the system partition is using test keys.

I haven't found an XDA thread yet that really provided deep insight into the algorithm that Google uses for Play Protect and SafetyNet. And given the proprietary nature of what it's doing, we may never get it. I think our best long-term solution is to get LineageOS 16 builds that pass CTS testing, but we may have to scrounge for 64-bit drivers.

 

[garyemiller]

I just went with Nova Launcher. It has been good to me.

I can wait for Lineage to catch up. I'm happy to be rid of bloatware. And with root I can block ads and my firewall works.

Thanks for the ROM! I'm happy!

 

[Magendanz]

Which stock files do I need to replace the nexus boot splash screens? I would like have the Samsung ones.

Just restore the original param image. (But seriously, why would you? The stock boot splash is ugly! )

Just ordered my T510, can't wait to try this out when it arrives

The 3G/128G config was selling for just $250 USD through Costco until a few days ago. That's a pretty insane value....as long as you aren't stuck with Samsung's One UI, that is.

 

[DarthGW]

will there be a new release coming?

 

[Magendanz]

will there be a new release coming?

Yes, I'm trying to build an unofficial LineageOS 16.0 release, but am struggling with some build issues. The primary goal is to deal with the Play Protect device certification (but I definitely won't pass SafetyNet). Eventually, I'll also get to fixing MTP.

 

[macapa1994]

wow dude, thanks a lot for you work
