@Magendanz

I'm having trouble installing Chrome web browser. Since I have been in the Google ecosystem for many years, I use it. Is there a way to install it? Play just says pending. I stopped it at 8 hours, restarted my tablet, then tried again, and it's been another hour now just sitting there at pending.

On a side note, I also cannot install Google Calendar, but I can work around that.

I must say, this was the most painless ROM to install on the tablet. Took me 15 minutes before work this morning. It's smooth and fast, without a huge footprint.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
My Chrome install from the Google Play Store worked just fine for me. Anyone else having similar issues?

Just confirming: You did a factory reset with Wipe->Format Data in TWRP, right?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] y0himba:
Yes. I followed the instructions in the original post, but before I even started the install I wiped/formatted. Then install, then another wipe to be sure, then boot into the new ROM. Which is perfection, by the way. Brought life back to my SM-T510.

I was able to get Chrome installed from APK backup, remains to be seen if it will update from the Play Store.

Thank you for the reply.

I have a problem

Every time I connect it to the charger in the off state

This starts the operating system

(instead of just charging)

can you fix it

Thank you

Do what I do - flash Andy Yen's GSI over this. Use the _bvN image, to get the one without Google. You get the best of both worlds. You benefit from Magandanz' efforts to get the vendor firmware for us, then use Andy's GSI builds for the OS. He generally updates every month with the security patches.

I have another problem that doesn't solve it

When I press power off

It takes 2 minutes for it to turn off.

Did you encounter a problem?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
This is by design. The Samsung Low Power Mode (lpm) only seems to be compatible with the system image provided in the stock ROM, and not anything newer. I spent days trying all sorts of workarounds, and eventually had to just settle for doing a system boot like Apple does in iOS. It's not what Samsung does, but it's much better than the alternative...which is for it to hang.

If you want to remove my workaround, just delete /system/etc/init/off_mode_charge.rc in TWRP.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
I'm pretty sure this is an issue with the LineageOS 20.0 GSI. I don't know about 2 minutes, but it does take a long time to shut down.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Android developer2:
I checked and it also exists in LineageOS 19.1 GSI
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Take a look at the logcat output during shutdown and see if anything stands out. Frankly, I just don't have the time.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Android developer2:
For anyone who wants to help us solve the problem

This is the output from the moment before I press the power button
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] DarkSteve:
:D

Thanks! I'll look into it. I thought Andy Yen's GSI was used to create the flashable ROM for each device, I didn't know it could be flashed over a working ROM.

I'm no n00b, but I'm also not particularly skilled either. But thanks for the push, I'll look into it (y)

While trying to install this rom via odin, I keep getting errors. Most often, "write operation failed". I have unlocked OEM bootloader, removed samsung account, on the latest official version, enabled usb debugging. Unsure if there is anything else that I am missing. I also get similar errors while trying to install the twrp separately.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
Is the correct firmware update installed?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Bharath Bhat:
I am able to install the rom successfully. I missed the step of actually unlocking the oem bootloader by a long press of volume up. Once I figured the issue, it went smooth.

I don't see imei numbers anymore. Is this usual?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
I was wondering that you are correct. I tried another way to use the dailer app, but this app isn't working because it can't be set as the default dailer app. The dailer option is not showing under default app settings.

Hi Kenaz,

How do you flash it ? Odin or TWRP ? The file is *.xz what can I do with this?

Can you explain please?

Thanks
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] treakeeog:
Yeah, you need to extract the xz file, inside you will find the img file which you can simply flas as system image in TWRP.

Alternatively you can just reflash your previous img, that fixed the issue for me once

Hello, I installed this ROM on my SMT510, thank you so much!!! I would like to create a swap file to extend the RAM from 2 GB to 4 GB. How shall I do it? I didn't find the usual Ram Plus option that is on Android 12+... where is it? How can I enable developer options?

Thanks
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
Developer options are default enabled under System in LineageOS.

With MTweaks, or other tool, it's possible to see and assign a Swap file.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] StefanoGiu:
Under System there is no developer option...

I installed MTWeaks from here (https://github.com/morogoku/MTweaks-KernelAdiutorMOD/releases) but it requires root and with LineageOS 20 it seems I don't have root privileges.

Can you please suggest?

My ROM is rooted. If you want then you can use the patched boot.img for LOS20 a couple post back. Install the image with TWRP.

Can you please pin point me to the boot.img to install ? How can I install it with TWRP? Shall I still use Odin?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] StefanoGiu:
So... I was able to root the tablet with LineageOS 20 and Magisk. Now root works and also MTweaks works properly.

I use this tablet to run the UI Lovelace of Home Assistant via Fully Kiosk Browser. The problem is that FKB crashes every 4 or 5 hours because it runs out of memory. That's why I decided to move from Android 11 to LineageOS and increase the ram.

I have installed also "Swap - No Root" and create a swap file of 4 GB, but when I enter MTweaks and go into virtual memory I see only 1,3 GB swap file. Moreover, if I open FKB and check for the free memory/total memory I still have like 200MB/2GB... I don't see the RAM increased.

Am I doing something wrong? Thanks for your precious help.

I would really like to get rid of these continuous crashes without having to buy a tablet of 400/500 euro to put it on the wall.

Thank you so much
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] StefanoGiu:
Any idea of what shall I do?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
If Fully Kiosk Browser do run the system out of memory then the problem is the app. I can't imagine the more RAM solves it. May be it give you some additional time.

Really?

The downloads on the first page are literally listed as:

lineage-20.0-20230901-UNOFFICIAL-T510XXU5CWA1.zip (TWRP update)

Which do you think should be flashed with Odin or TWRP?

I'll give you a hint:

lineage-20.0-20230901-UNOFFICIAL-T510XXU5CWA1.tar.md5 (Odin tarball)

lineage-20.0-20230901-UNOFFICIAL-T510XXU5CWA1.zip (TWRP update)

Alternatively, you could try using Odin to flash the zip. It won't work. Or you could try flashing the md5 via TWRP. It won't work.

Yes, I got my bootloader unlocked.

Hi everyone!

I'm new to posting on XDA but have some experience with AOSP development. My trusty SM-T510 still has life in it, so I've decided to pick up the development torch for this device.

Building on Magendanz's Foundation

A huge thanks to Magendanz for their initial work on the recovery and device tree. My goal is to create a more tailored and "official-feeling" LineageOS experience for the Tab A, starting with 19.1 and 20.

Moving Beyond GSIs

While projects like PHH and AndyYan GSIs bring new life to older devices, there are limitations. With Google ending official security support, backporting patches becomes trickier, and our aging hardware makes achieving a smooth experience tougher.

The Challenges Ahead

RAM Restrictions: Modern Android versions ideally want 3GB+ of RAM, something our Tab A lacks.

Outdated Kernel: We're stuck with a legacy kernel (4.4.xx), while newer Android requires features like eBPF that we don't have.

Aiming High, Staying Realistic

I love a good challenge! While a perfectly stable Android 12+ build might be out of reach, I'm committed to creating the best possible LineageOS experience for our SM-T510 within its limitations.

Let's Collaborate!

If you're a developer, tester, or a user of the Galaxy Tab A, I'd love to collaborate. Join the org. Let's see what we can make happen!

gta3xlwifi-development

Cheers!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] DarkSteve:
Has Magendanz stepped down/stepped back from leading development? His initial work? I've been using his builds since LOS16! (Up to 18.1, I don't like GApps! :p )

I've very happy you've thrown your hat in the ring, I can't code to save my life, otherwise I'd help. I'm just surprised your post is implying Magendanz is passing the torch.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ramenrolls:
Well, he's laid the groundwork with the recovery trees and builds.

He has several tablets in his arsenal, which he intends on building more recovery trees and foundations for further builds. Newer tablets.

His Lineage builds thus far, work great. Some kinks here and there, but as an unofficial GSI build. Of course there are.

Maintaining those builds would be a whole 'nother animal. No need on his end for that sort of upkeep, especially if it's a device that's not a primary device. Time consuming, especially if you don't really need or want to.

I will keep that in mind for future builds, as people like to choose GApps or GApps-free builds. Keep in mind, very much in 'alpha' stage of developing. Working on the device tree, and compiling against AOSP source. So fighting errors as they show up.

I got this tablet since it came out so never felt the need to upgrade, I got some skin in the game. I'm a 4th year EU medical student, so this is sort of a side gig for me. I enjoy it, i'm a full blown nerd for sure.

If you would be interested to learn, plenty of resources online for rom development. Anyone can get into it, truly.

Give the GH org. a follow, if you're interested to see progress.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] DarkSteve:
That would be greatly appreciated. Especially now, as the official LOS code enables signature spoofing for MicroG.

MicroG has reached the point it can replace GApps for most use cases, it's weird to bundle google's malware with LineageOS by default.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] icdmize:
Is lineage-18.1-20220907-UNOFFICIAL-T510XXU5CVG2 still the most recent build accessible? Have there been no updates since August of last year, or is there something I am overlooking?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ramenrolls:
Since newer builds get more attention, there isn´t a great deal of demand for 18.1.

If you prefer it, I would be willing to compile it. With GApps, or without. I couldn´t give you an exact ETA. It might take a little time since there's less interest, but I'm committed to providing options for everyone.

Feel free to swing by my GitHub organization to track progress, suggest features, or report any issues
