I don't believe that's accurate. A64 should mean it includes the lib64 and 64 bit executables in the bin directory. But, 64-bit is not activated if 1. You don't have the arm64-v8a in the CPU capabilities list on the vendor build.prop and 2. you don't have the lib64 folder in the vendor folder. The 64 bit binder is required for Android 9+.

Working on a 64-bit port now. More info soon.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Yeah, I originally thought that A64 was just the "32-bit fixed-length instruction set that machines in AArch64 state execute"...basically just the ARM64 instruction set. However, I'm seeing "arm-32-binder64" releases with "treble_a64_bvN-userdebug" in their build descriptions and fingerprints that have no ro.product.cpu.abilist64=arm64-v8a in their build.prop or lib64 folder. Is this someone's new definition of "A64"?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ibanezbass:
Any idea what's getting added to the vendor partition when flashing this rom? The lib folder is using all of the space, which leaves none left for lib64 :(

what GSI Roms have you tried an that is bootable on SM-T510?

would you been kind to start creating a list with links of the working gsi roms for the SM-T510? or just the names of working gsi roms!

i got HavocOS A64AB android 10 to boot but no gapps so i reflashed my TWRP backup of nexus stock

Is it possible to format sd card as internal storage? I don't get the option on this rom, I think it's called adaptive storage? Is this some Samsung thing that it's disabled and is it possible to enable?

Hello Magendaz,

I'm facing a new issue with the bluetooth. I'm connecting a bluetooth ring scanner (RS507) in HID mode. When I scan a barcode, it's switching some letters which is very anoying. I haden't the issue with the official rom!

regards

I found that it was due to the virtual keyboard that was too slow to display / hide. I used another one hidding himself when physical keyboard is detected and everything looks great now.

Could you please add lionheart and bioshock to the kernel and share it ?

Thanks a lot!

Although not sure but i think the GAPPS go to vendor partition too , atleast OpenGapps pico does

---------- Post added at 02:04 AM ---------- Previous post was at 01:53 AM ----------

YES i would love to maintain a list .

I'll make one on Github and share it on 2nd January as im having my finals right now :crying:

I'm going to test out all the compatible GSIs after my exams and add them all.

For now though i can confirm that HAVOC OS 3.0_Android10 A64AB unofficial works but no gapps like you mentioned.

Also Descendant OS PIE arm32 works albeit with some random stutters once in a while

AND EvolutionX 2.0 PIE official A64AB works

and lastly i tested the PixelExperience PLUS pie A64AB working as well.

ONLY flash pico gapps if you want.

though EvolutionX and PixelExperience has GAPPS included.

I hope this helps :fingers-crossed:

Have Fun !!

EDIT:

Sorry, minutes after posting I found the error:

I had 'system' mounted in TWRP. Make sure after boot into TWRP that 'system' is unticked under 'Mount'...

________________________________________________________________________________

Hi there,

Not sure it's an issue with the ROM or TWRP or Me (very likely) - but I cannot flash Magisk from TWRP. It shows a fail as it 'cannot mount /system'.

What I've done so far:

- Unlocked bootloader

- flashed this rom (incl. TWRP) via Odin

- booted into recovery (and system and back in recovery, all good)

- In TWRP format data

- tried flashing Magisk 20.1 and 20.0

Now I just recently rooted a Galaxy Note 9, no problems and apart from the Bixby button a very similar process. Never had this error ever before.

I did swipe to allow modifications in TWRP btw as with the Note 9.

Anyone got an idea?

Thanks a lot for your help in advance! :)

The same happened to me I just rebooted to recovery from twrp and tried flashing it ,then it started working.

---------- Post added at 08:27 AM ---------- Previous post was at 08:12 AM ----------

If you are rooted

Go to play store download app2sd

https://play.google.com/store/apps/details?id=in.co.pricealert.apps2sd

There would be an option there partition tool adoptable

Toggle the adopted option there if it's portable .

Then click on the bottom left and choose create and then press yes .

Voila your ad card is adopted

If no root

Format the SD card to some unknown format.

The table would say SD card corrupted tap to fix.

Then it would say format the SD card to continue ,press cancel

Then select add storage and continue.

Hope it helps.

can you make that list of working gsi roms with links?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Note that a fresh release has just been posted, based on T510XXS2ASK1.

I spent the weekend working on a fix for the cold charge hang (boot to LPM), but nothing is working and I'll probably resort to a kernel fix. That will mean that we'll need to maintain two kernels, one for the OEM system images and another for GSIs like AOSP and LOS. That said, it will also allow me to fix the MTP bug when USB debugging is disabled.

The LOS 17.0 builds are also progressing nicely, and I expect to have a Nexus Stock build based on that ready for release soon.

Is there a tablet version of this rom? The notification status bar etc are all in phone mode. Not sure if something is wrong here or I'm missing a setting?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Well, Android doesn't have a ton of differentiation for tablets, but I will admit that the current build.prop sets ro.build.characteristics=default. Technically, this should be ro.build.characteristics=tablet, which it will be in future releases. Not sure how this will manifest in the user interface, but I'm pretty sure that the difference will be subtle.

I changed it to tablet with build prop editor. After reboot nothing changed. Any other ideas ?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] VeganaSatana:
Fantastic ROM as always :) . Only issue I'm having is I can't get Magisk to pass SafetyNet. It shows ctsProfile: false, basicIntegrity: true, but on the last version of the ROM they both showed true. I even tried changing the package name but that didn't help. What am I missing?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] VeganaSatana:
So after doing some digging it appears that the "fingerprint" on this ROM uses some generic test keys, and that's why it won't pass. There's a nifty Magisk module to change the fingerprint, but I don't have the proper one to change it to. Anyone that's on a stock rom could look up the proper fingerprint perhaps?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
That's because I didn't run phh-securize.sh for you this time, since I wanted to keep the LineageOS su extra intact.

To do it yourself:

Enable root access and local terminal in Developer Options

Open Terminal and issue the following commands:

cd /system/bin
su
phh-securize.sh

When the prompt comes up to allow root access after the su command, make sure to give it permission. If all goes well, the device will reboot and you'll no longer have an option for root access in Developer Options.

What's the general consensus? Do folks want me to run phh-securize.sh as part of the build process, even if it kills all the LineageOS built-in root access features?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] VeganaSatana:
Thank you for your response :). I had actually gotten it to work with a Magisk module called SafetyPatch. Whatever it did fixed it, but now I know the proper way for next time.

As for my vote, Netflix won't even show up in the Play Store, much less work, unless the device passes SafetyNet. A tablet that I can't watch Netflix on is pretty lame, so my vote is that you do what needs to be done to make sure it passes by default.

I just patched latest TWRP with latest Magisk and flashed it in recovery and booted recovery, the tablet keeps looping on "phone starting" with security pin or no pin " so rebooted the tablet and checked from magisk manager recovery mode and now the tablet keeps "phone starting forever, can't boot into fastboot to reflash TWRP or to TWRP.. any ideas for help :D ?

UPDATE: Nevermind, managed to get back into recovery and re-flashing again the rom :)

---------- Post added at 02:26 PM ---------- Previous post was at 02:06 PM ----------

However, what are the correct steps to have magisk on this tablet? I thought it should be:

- Get the twrp "recovery.img" from the tar

- Install Magisk manager

- Install Magisk "chose to patch a file" pick the recovery.img

- reflash the recovery.img even with twrp if you wish

- everytime you need to boot the tablet, boot it into recovery

optional: follow the steps https://xdaforums.com/showpost.php?p=81475231&postcount=328 here for SaftyNet..

is that correct? am I missing something? why the phone kept looping trying to "start phone"?

I flashed the latest 20200103 but all I can see that the image is compiled built on 7th of October 2019, I used to have the normal LOS rom, then wiped everything ad flashed the zip file from here from the OP, is that normal to see old dates of the rom?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Yes, that's the latest build date of the LineageOS 16 GSI from [MENTION=4467696]AndyYan[/MENTION]. At some point I might start building those myself, but I just haven't had the time and Andy has moved on to LineageOS 17 exclusively.

TWRP can't backup encrypted partitions and the data partition is encrypted on the stock ROM.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] demoneg:

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Not if you want backup to work.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] demoneg:
TWRP backup you mean?

Okay, what did change to make TWRP not able to ask for the passphrase and decrypt the data and take backup?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
I'm not certain. I believe what changed is Samsung's encrption method. But I know it no longer works.

- reflash the recovery.img even with twrp if you wish

- everytime you need to boot the tablet, boot it into recovery

Appreciate it but that would put me back to scratch obviously and I dont want that. Just option through twrp which I was told not doable because of encryption. Thanks anyway
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] woundtrauma:
Have you heard of Titanium Backup? It's good app. All you need to do is to make a backup of your apps, save the backup folder, flash image and then restore your backups. That's how I do things with my Essential Phone, since TWRP is not really practical for it, due its partitioning system.

Hi guys, I install this rom, everything looks fine but launcher seems to me laggy and all animation of transaction ecc..., is this okay?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
I've found that the scrolling is pretty smooth as long as you've set debug.sf.latch_unsignaled=1 in the build.prop.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] StarGeneral:
Thank you again for your great work. Is there any way to confirm that the flash of the recent version worked? My tablet still says that is is running an older kernel and older build in the "about - system" area.

I think the flash worked concerning the TWRP-logs, but i am not sure.

Moreover, the device says that it has been build with public keys and that this is a security issue - is this correct or did i miss something?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Currently, I don't update the fingerprint for incremental Nexus builds, so it will just show the build of LineageOS and the underlying kernel version. That will probably change with the next release.

We actually build "userdebug" with the platform keys, since we're not Samsung and don't have access to their release keys. Consequently, there will be some features dependent on SafetyNet that won't run, despite efforts to spoof that as best as possible using [MENTION=1915408]phhusson[/MENTION]'s "securize" feature. I don't see that changing anytime soon.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] StarGeneral:
Thank you very much for your answer. Everything is fine then.

Is there any possibility to get the "Charging while turned off completely"-function going? This would be very nice :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
That's my biggest priority right now, but none of the usual workarounds are working. Even my attempts to edit the kernel source aren't making any difference. Given that this is a pretty generic problem with GSIs, I'm surprised that no one has documented a "best practices" fix.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] yozart:
Great that you try to find a fix !

I just found my tablet completely discharged. how can I charge it again ?

Edit: Finally, it seems to charge even if charging logo seems stucked. To restart the tablet, I need to unplug cable, press power button and connect again cable when screen is showing something.

The only ROM for the T510

Thank you, megadanz for building the only viable custom ROM for this device. I eagerly await the next update.

I'm curious, do you have any idea why others aren't interested in this tablet? I see so much on the forum for older devices, but nothing is expanding to include this. I bought this because it is a good device at a good price.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Well, it's a relatively new device, but I'm also surprised that more custom ROM developers aren't targeting it. Both Costco and Amazon have been selling the SM-T510 at incredible discounts, so I suspect there are quite a few of them out there.

I just feel guilty that I have so little time to set aside for this project. There are fixes in the works for double-tap to wake and cold charge, but it requires me to start building LineageOS from scratch (vs. from [MENTION=4467696]AndyYan[/MENTION]'s prebuilt GSIs). Usually, I only have a day every few weeks to dedicate to that work, and so far it hasn't yielded any usable results. (Building TWRP or a custom kernel from source I find to be much easier by comparison.)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:

Not sure what is going on, but I can't install other browsers from the Play Store. I've tried installing Brave and Opera. Neither will install. All I get is "cant install" error.

No, I don't believe it has a vibrator. At least, I wasn't able to get vibration working on the OEM firmware either. (However, I am noticing that there are part vendors selling replacement motors online. That makes me wonder.)

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:

Follow the directions!!! Though the word "stock" appears in the title, it is NOT T510 stock and can't be flashed via Odin without first installing TWRP and formatting the data partition. It is actually easier to flash the TWRP version.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Um...you actually should be able to install the tarball (.tar.md5) using Odin, and it will include the TWRP custom recovery. When Odin reboots, you will automatically be taken to TWRP to format the data partition and can then reboot to system.
