Transfering files from PC to internal memory or card SD not working. Is only charging. If you switch to transfering files-nothing happen. Another bug wha i find is Magisk. When i install Magisck via TWRP i have restarts every 1 minute.

Can we expect this rom to work on SMT295 LTE version
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] detroitredwings:
I can confirm - right after I flashed Magisk.zip via TWRP the tablet reboots by itself every minute or so. I guess I can reboot to recovery, wipe/format and reflash the ROM, but I need root, which means I need to flash Magisk... any ideas?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] djrexy:
probably i'll be back to stock rom and then push magisk
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] detroitredwings:
By "push magisk" you mean flashing it in TWRP?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
That file transfer is called MTP, and it's listed as a known issue. I've fixed it with a custom kernel build for TWRP, but that breaks WiFi (seemingly due to some issue with enforcing SELinux). Losing wireless networking is fine for TWRP, which doesn't use it, but not for the main system.

As for Magisk, I don't use it and so don't test it. You'll have to troubleshoot that on the Magisk forum.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Mitar00:
When are you dropping the android 11 build brother? I'd gladly test it if you need.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
As soon as we get a stable ARM64 build of OpenGApps for Android 11. We finally got an update on May 13th (after almost 4 months) and it's giving me a black screen during setup.

I got netflix working by downloading the latest netflix beta apkm from apk mirror, then installing it with the apkmirror installer.

However, widevine drm is on L3 status on almost every custom rom, that means that you can't play HD content, there is a hack to fix it but it relies on Magisk, which doesn't work on this rom for the moment.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] mateuxi:
Just installed and thoroughly tested the latest build of your rom, it is smooth and stable as f*k. There was no way to get the poor thing to run as fast on stock, thanks. The only problem I've found is that Magisk makes the system restart one minute after it boots, but the rom allows for root over adb and that has been enough for my needs.

Once again, thanks for the incredible rom, you have been singlehandedly carrying the entire rom development community for this device.

Hi, I tried to use the mic on a zoom call and discovered that the mic (and audio in general) isn't working right, I tried changing all the configs related to audio in Phh config and still nothing (in any audio recording app, not just in zoom), I could get a bluetooth headset working, but then the mic would work but the audio would still go through the speakers. Any ideas for a workaround?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] V0latyle:
I was having the continuous reboots on the January build, so I updated to the May build, and now the tablet only boots to TWRP. Any ideas?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] mateuxi:
Have you tried flashing T290XXU3BUC1 system before the ROM?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] V0latyle:
I flashed the multidisabler which fixed it for some odd reason.

Is anyone else stable with Magisk on this?

I started from scratch with the BUC1 firmware. Flashed TWRP, then this ROM. If I flash Magisk, I get boot loops.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
Did you patch the boot image in Magisk Manager?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] V0latyle:
No, I just flashed Magisk via TWRP.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
That is the reason why you gave bootloop
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] V0latyle:
How do you figure? Flashing Magisk via TWRP patches the boot image.

I installed Magisk on the tablet, but it crashes on startup. I'll try patching the image but I'll have to do it on another device.

I'm not even sure how to flash the boot image since Samsung doesn't use fastboot.

Is MTP working for anyone else on this ROM?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] cossak2007:
Would love to flash this rom .

Don't know where to post my problem so I am apologizing for posting it here.

After the April security update , I had an issue with MTP file transfer .

Only charging... no options to file transfer from notifications and Developer options set to file transfers.

Only charges when plugged into my Windows desktop and laptop.

Different cables , new cable , different ports etc.

Spent hours with Samsung support with no solution.

Searched all forums .

Thought it might be the software so waited for the Android 11 update.

Did not solve the problem.

Purchased a new USB board and after installing it, it still only charged tablet.

Could the problem be the main motherboard ?

Anyway to flash roms without a USB Odin connection to computer?

Tablet had been rooted before but with minimal custom roms, I reverted back to stock and locked bootloader.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] V0latyle:
MTP doesn't seem to be working on the May update of this ROM. I went back to CUF8 stock, MTP works.

Sounds like you had a bit of a frustrating experience. Are you saying MTP isn't working on this ROM, or that MTP isn't working at all? Have you been able to flash TWRP and use MTP?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] cossak2007:
Would love to flash this rom but cannot due to MTP issue mentioned above.

Rom sounds to be awesome but need to fix whatever wrong with my tablet.

Software or hardware I dont know .
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] V0latyle:
Have you tried flashing back to stock Samsung firmware? MTP works for me on both the stock firmware and TWRP.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] bignikescar:
For some devices Unlocking bootloader could be done in a different method.

I managed to flash the rom but I keep running into issue with sd card, any fix regarding this; I can't use my sd card with this is what I'm saying.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TheLoonyRebel:
Looks like we got at least a few OpenGApps ARM64 packages (pico, nano). No idea if that helps you out but that's there for an potential Android 11 ROM for the T290.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Well, I use the Stock package for this custom ROM, but I have released Nexus Nano variants in the past. That said, I was able to create my own Android 11 Stock package from the latest Nano and the Android 10 release of Stock. I did this for the SM-T510 (ARM), but would feel much better having an official release.

It's just hard to justify investing time in building and testing Android 11 Stock packages when it keeps sounding like the official ones will be here any day now. (Of course, the last Android 11 Stock ARM test release was in January.)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TheLoonyRebel:
I totally get what you mean and yes I would feel better with an official stock release as well. On that note any idea if the A11 kernel source might fix the MTP issue? Or is that basically an fix that needs to be done in the coding itself for the kernel?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Well, I can build a custom kernel that fixes the MTP issue, but it ends up breaking WiFi. I think there's some undocumented setting that's needed to address an underlying dependence on SELinux. Without it, the WiFi drivers won't load. This problem is specific to the SM-T290, since I have no problem building custom kernels for the Eynox-based SM-T510.

That said, I haven't tried building the new Android 11 kernels (CUF8 and CUG4) yet. Maybe they fixed it?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TheLoonyRebel:
I'm more than happy to help beta test on my tablet if need to be. I already have the current A11 build backed up on TWRP if I need to go back to that.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
On Monday I put in the request for CUG4 kernel source, so let's give that a shot when it's posted. Maybe we'll get lucky and OpenGApps will have an official Stock release by then too.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TheLoonyRebel:
Thanks. I'll do one more backup of my current setup before testing any build you might upload. Curious if no stock OpenGApps is available maybe an ROM build using pico or nano could suffice (maybe call it slim build or something)?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
I did a Nexus Nano build just for grins earlier this summer, and it didn't pass muster. I'm more comfortable just making another custom OpenGApps Stock based on Nano and the Android 10 Stock.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TheLoonyRebel:
I just noticed this unofficial stock ARM61 for A11 one here done by ripee:

20211008 - Google Drive

20211008

drive.google.com

Would that work for bundling in with an potential A11 ROM for the T290?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Any GSI should work, but ensure that it includes the @phhusson patches.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TheLoonyRebel:
I'll test this weekend and will let you know how things go.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TheLoonyRebel:
So I am assuming this tablet is A-slot partition only since TWRP has no mentions of switching slots? Tried using CRDroid R Mod but bootloops on the SAMSUNG screen (A-Only ARM64 build 21.09.21).

Edit: Went back to my stock backup (A11 August 2021 update). Treble Check says A-slot only which I suspected. Should I flash the GSI over stock? I tried clean and no go won't boot past the Samsung screen.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Heeni:
According to https://play.google.com/store/apps/details?id=tk.hack5.treblecheck, this tablet needs AB roms. I've been running AB roms on this tablet successfully for over six months now.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TheLoonyRebel:
Working now. Thanks for point that out to me. This tablet is so much better without the Samsung bloat.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Chameleon2000:
Sorry to have to write this but I'm having a lot of issues with my tablet. I'm sure the author has put a lot of work into it to get it to this stage.

I'm using the current latest download.

Nexus_Stock_LQ_T290XXU3BUC1-20210516.tar.md5 (Odin tarball)

Nexus_Stock_LQ_T290XXU3BUC1-20210516.zip (TWRP update)

If its anything my tablet was bought in Aus. I used odin to flash twrp from the included link and then installed the nexus stock using twrp.

Maybe my download was corrupted? Was I meant to use the tar.md5 file with TWRP instead of the "TWRP update" zip?

Not only does the SD Card constantly become "corrupted" (Its not, put it back into my windows pc and it works fine Samsung 256GB Evo, was working fine on the OEM rom.) but I cannot even use the tablet with adb because as soon as I run "adb root"

the tablet drops the connection with adb and becomes unresponsive with adb requiring the tablet to be rebooted before attempting another try connecting with adb. In addition to this I cannot connect with adb via the network, it refuses to connect. Also I cannot access the internal storage via usb file transfer with this rom as stated on the first page this rom has no MTP support.

With the SD Card, I cannot access any of the files when booted into the system, however TWRP can access the SD Card with no problems? This allows me to transfer files from microSD card to the internal storage by using TWRPs file manager. (But the storage/emulated/0 partition isn't mounted? when I go into /storage when in TWRP the folder is empty.)

After that it becomes unresponsive unless I reboot.

Aside from these faults it seems to be "workingish", it seems stable. No issues with charging unlike some other people are having. Can set a pin.

At least the wireless works. But good luck trying to actually use the tablet without having to download everything from the internet, there is no way that I can transfer files locally to this tablet from my pc without running a locally hosted web server or ftp server.

Any ideas? I haven't signed in using a google account. should I? Is that the issue? I did do a format before installing the nexus rom. Followed the instructions exactly.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
So, the issue here is the OEM kernel, which implements a proprietary Samsung version of the USB gadgets (e.g. MTP and ADB). When source is made public, I can build a version of the kernel that implements the standard MTP and ADB for Android GSIs, which I then bundle in TWRP so that it's fixed in that environment.

The problem is that every custom kernel build that I've made with the public OEM source breaks wireless support. This isn't really an issue for the TWRP environment, but is a bit of a deal breaker for booting to system. If I have to choose between MTP and wireless, I choose wireless every time.

Now, if someone can help me figure out how to build the kernel in a way that doesn't break wireless, I'm all ears...but I've dedicated several weekends to troubleshooting at this point and have basically given up. There was a hope that the Android 11 kernel just posted (T290XXU3CUG4) would have fixed the problem, but I confirmed yesterday that wireless is still broken for those local kernel builds from the Android 11 public source.

By the way, I'll be retiring this Android 10 custom ROM now that we have an Android 11 OEM kernel (which doesn't support Android 10 GSIs) and official Stock builds of OpenGApps for Android 11. This issue will still be present going forward, though...at least until we can successfully build a kernel with functional wireless support.

Grate work i had some difficulty but i got it done and now my tablet is running grate without all that Samsung crap and Samsung UI ( one of the worst UIs ever made )

for anyone who says it wont work on the new ones ( Tab A T290 Walmart purchased 10/15/2021 ) it defiantly can

enable dev mode

enable OEM unlock

downgrade with Korean dev firmware

install old version of TWRP ( oden3b AP )

enjoy root for a bit...

update to new version of TWRP ( this will soft brick but its ok )

use TWRP to install Nexus_Stock_LQ_T290XXU3BUC1-20210516

ENJOY

there might be a faster way to get the end result but IDK...

thank you for your hard work and making this possible
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Chameleon2000:
The other issue with this is that seeing as you cannot access the decrypted system partition and there is no ADB you cannot transfer the patched magisk boot.img file from your tablet to your pc to be uploaded again via adb or Odin. Found that little problem out myself.

This sucks! I'll have to buy another tablet and phone because I've also been waiting for a custom rom to be made for my phone too and the phone is damaged now and is due for a replacement... I really hoped I could get a custom rom for my tablet and my phone but development is to me bricked because of Samsung's tampering.

And Development is so slow to non existent in general because of manufacturers proprietary code and locking down their equipment that the devices that people buy are obsolete or become broken by the time a rom is made that works because of the proprietary code. I think the last phone I bought was already 2 years old when I had a working LineageOS rom for it.

Really wish we could just install LineageOS on any piece of hardware we wanted. I'm sick of manufacturers locking out developers and forcing Google code down the throat of everybody.

The other issue is that most good LineageOS approved phones are really expensive and don't get me started about the price of a Librem phone.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
You can still use a microSD card or MTP in TWRP to transfer files.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Chameleon2000:
Yeah I'm having a problem where TWRP after its flashed to recovery won't mount the system partition as decrypted, I just get garbage folder names whenever I view the system partition in TWRP when I load TWRP from recovery so transferring files to and from microsd card is impossible. I've installed the Multidisabler zip file (multiple times) thats recommended on the TRWP page that you linked to but it still won't work. I'm having issues with that.

The multidisabler zip works on the initial twrp flash but once you install twrp to recovery permanently the multidisabler no longer works. Its not permanent? Do I have to keep reinstalling multisabler every time that I need to access the system partition?

For now I'm just going to reinstall the stock firmware and modify it and uninstall the samsung apps and google apps that I'm not using and install microg and other stuff that I need back onto the tablet via ADB. Until I can get the multidisabler to work it'll have the stock OEM ROM.

Again thanks for all of your development on this rom but I think its best that I just go buy another tablet one thats better supported.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Yes, I've not cracked Samsung's file-based encryption (FBE) used in the userdata partition yet, but that's not applied to removable storage and so you can access microSD cards and USB flash drives from TWRP just fine. Note that you can install the version of Multidisabler that removes encryption, but then the screen lock feature stops working on this model.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Chameleon2000:
ok I'll give it another shot. Reason why is because I just tried removing certain com.samsung apps and failed spectacularly, causing a bootloop. I'll reinstall your rom and run a ftp server on the tablet and pull any files that I want off that way. I cannot transfer files to and from the system/userdata partition even in TWRP because of the encryption which is what I was having problems with. I wanted to transfer the patched magisk boot image off of the system partition onto the microsd card so it could be accessible in twrp for flashing. Thats what I was trying to do before. But patching the boot with magisk won't work will it? Just tried it and it caused a bootloop. Gotta patch it with recovery? or is rooting this rom not possible?

There are a LOT of samsung bloat apps hidden in the background on these tablets! I didn't realize just how many there were.

Thanks again for your free tech support. I really need to reread this thread.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Chameleon2000:
I found a "bug"... In my router I've set so that all of b|g br0th3r$ stuff is blocked by default so no android or snapple devices will be able to detect if they are connected to the internet and spy on you even if the device is running OEM ROMs. The only issue with this is that with this rom it won't auto reconnect to wifi if you reboot the tablet. In addition to this when you select "Do not prompt again" in the dialogue box where it asks you if you would like to stay connected to the wireless network, It doesn't remember this setting. It forgets this setting.

This is probably just stock rom behavior and has nothing to do with your development. But I thought I would just mention it anyway.

Hi,

Many thanks! Great job! Almost everything works pretty fine.

Question: is it possible to have this rom without gapps? Or can you explain how to remove/uninstall these gapps?

Thx in advance.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Just boot to TWRP, mount the system partition, and start deleting what you don't want. Focus on the /apps and /product/apps folders.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
New Android 11 release is finally posted. Note that we're now constrained by the system partition size, so I had to trim some of the stock OpenGApps (e.g. Maps, Duo, Messenger, Android Auto) to fit in the available space. Also, you'll need to do a clean flash on top of the OEM T290XXU3CUG4 release because we're moving to an Android 11 kernel. Dirty flashes are not possible (which is why I've disabled the link to the TWRP update). Finally, because we've reached end of life on the Android 10 releases, I've now highjacked this XDA thread for Android 11.

Downloads:

Nexus_Stock_CR_T290XXU3CUG4-20211121.tar.md5 (Odin tarball)

Nexus_Stock_LQ_T290XXU3BUC1-20210516.zip (TWRP update)

Change Log:

20211121:

Updated to Android 11 OEM stock T290XXU3CUG4 kernel (July 2021 Update).

Switched underlying GSI from LineageOS 17.1 to CAOS 11.

Updated TWRP recovery to v3.5.2_9-1 (20211017).

Updated Google apps from latest OpenGapps Stock variant (20211120) w/ rollback for WebView

IMPORANT NOTE: Dirty flash is not possible because we're transitioning to Android 11 kernel. Use Oden and do a factory reset from TWRP.

You Rock Magendanz!!! Thank you so much for your hard work and continuing development. Phenomenal move to A11 BTW. Any chance you might TWRPify this rom?

Really appreciate the fine work you do and have been watching for a while. I have several of these and several of many, many others (tabs, phones, etc) and normally stick to my own development, but I just wanted to chime in and thank you for keeping the sm-t290 custom rom dream alive.

Thanks again...Flashing now:)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] gigahurts:
Flashed it semi dirty, without the base, sorry no time. This ROM works absolutely flawlessly! No issues whatsoever, everything works perfectly.

Also a side note, Magisk (ty John Wu) 23.0 installs and functions perfectly. I did have some spontaneous reboots after spoofing pixel 5 and enabling safetynet in phh misc settings and also using Magisk hide... Rebooted about 30 seconds after lock screen, but I undid those sliders and I have root on A11 and am very pleased with the performance and have zero issues (other than failing safetynet, even after flashing the safetynet fingerprint modifier module in the Magisk manager. Oh well...

Thank you sir for your hard work and dedication. I will let you know how it goes with the sm-t510 shortly. I also have the A7 10.1, s5e, s6, s7 and s7+ among many others.

Cheers, how's the weather in WA? Was born in Seattle, I know how it is.
