I had a scare with my t500. I installed the 3.6 TWRP but hadn't tried a GSI yet. Turned it off and tried to restart it the next day. It wouldn't even reach the first screen. Backlight would show for a couple of seconds and then turn off again. Couldn't even use the key combos to reach download or recovery. With or without cable plugged in. Thought I had completely bricked the tablet. In desperation, I taped down the power button to try to run the battery down. I happened to glance at about it about 15 minutes later and the second splash screen was showing. Took off the tape and now it is booting normally. But TWRP is gone. Back to stock recovery. I know a stock ROM will overwrite TWRP if you let the tablet boot to system instead of recovery when you first flash TWRP. But I've never seen it do once TWRP had been entered.

hi

can this be used on sm 505 ? r they same in kernel ?

cause i googled but no idea if they have same kernel ...so same twrp can work both ? am i right ?

thank u in advance

It should work but you never know until somebody tries :)

I tried installing the Pixel img using this method. It got almost to the end a failed with the message that remote operation wasn't permitted.

@lewmur: a better guide is in https://xdaforums.com/t/guide-sm-t5...flash-lineageos-or-any-other-gsi-rom.4378017/

Please ask there if you have *general* questions about GSIs.

This thread should be kept for TWRP issues only. AFAICT fastboot works fine and I was able to flash all working GSI builds (PixelExperience included, I have no clue why people love this rom!?).

Keep in mind that flashing logical partitions from TWRP itself (by mapping /dev/block/dm-0 to /system_image as an emmc mountpoint) or using a 3rd party patch (like Dynapatch) is error-prone and should be avoided. If you tried that in the past then please restore the super partition from a backup or from a samsung firmware package before attempting to flash logical partitions from fastboot.

Then follow the new guide, replace Lineage with the rom you want and try again. If you still find an error while in fastboot with a stock super partition then copy/paste here the error it throws.

is there anyway to use adb to do an install?

I'm a linux user, tried odin software before but it wouldn't work under wine :(
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] paziusss:
Just use heimdall. Download it from https://github.com/amo13/Heimdall/releases/tag/v1.4.2

You can use https://wiki.lineageos.org/devices/gta4xlwifi/install#installing-a-custom-recovery-using-heimdall as a reference.

It does work using a Windows session in VirtualBox. I've done it.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] punteruk:
yeah but don't I need a copy of windows for that? gave up on windoze years ago :p
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] paziusss:
What doesn't work and how?. If you're talking about the heimdall aur package that's expected. You need to download the binary from the link I gave you, which contains PRs not yet merged upstream and needed to support this device.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Yes and no. You do need a copy but you don't have to activate it. You should be able to use Wine to get the Media Creation Tool to download a Win 10 iso and use that to create a Vbox session. Then you'll have several days to use Odin without activating Windows.

Presumably the blank vbmeta is obtained from one of the other threads..

TWRP won't stick for me, after successfully flashing both tars in Odin the system reboots with stock recovery. I'm pretty sure TWRP needs to be booted first, but there's nothing in any of the threads outlining how or when to boot recovery.

Kudos to all involved, it's appreciated (y)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ragarcia87:
You'll need to use multidisable in TWRP.. when you are in Odin before you flash, make sure to untick the Auto-Reboot.. then after it Passes, leave it plugged in via USB and hold down the buttons Power + Volume Down to make it Force Shut Down then Power + Volume Up to boot into TWRP before it has a chance to reboot and remove TWRP.. Then flash multidisabler.

Nice work..

My 3.5.2 build also has Fastboot and it works perfectly btw.... lol.... I just use TWRP to flash GSI cause its how I liked doing it... but Fastboot works on my recovery as well..

//EDIT//

My 3.5.2 fastboot doesnt flash lol... but my 3.6.0 build does... smh.. wont update my thread withupdated 3.6.0 due to you having one already here..
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] punteruk:
yeah could be the AUR package.......this tablet is turning into a massive PITA lol

now it doesn't do anything when I hold the vol + and - keys to get in into download mode...

if I use 'adb reboot download' it goes into download mode but I don't get the extra writing in multicolors

Also I'm not on the latest Samsung firmware...should I relock the bootloader and update too? that's another PITA :(
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Tirofog:
Thanks, got TWRP to stick after some perseverance..
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] punteruk:
houston we have a problem lol

ok so I got heimdall to do this:

sudo ./heimdall flash --RECOVERY recovery.img --no-reboot

but then I reboot and got the following screen (I tried both the power/vol up and vol down combo for 7 secs but it reboots to the same screen, yikes
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Tirofog:
Looks like the blank vbmeta wasn't flashed. I'm not familiar with Heimdall, but you should be able to get to download mode by holding both volume buttons and then connecting usb. From there I guess you're going to have to flash back to stock and start again, at least that's what I had to do but using Odin.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] EdwardTCM:
Gotta reflash the stock firmware + stock recovery and try again (that's what I do)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] EdwardTCM:
Idk how to work Heimdall so I'd recommend you go look it up unless you know how to reflash something
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] punteruk:
quick google suggests I should have done this after the 1st heimdall command

heimdall flash --VBMETA vbmeta.img

need a blank vbmeta and hopefully @paziusss can confirm? he seems well clued up

and why did the lenovo X606X tablet fix this with the firmware screenshot ( page translation

Removing the warning about the unlocked Orange State bootloader.

I did it at the request and with the assistance of (testing) participants of the smds Virtualiy topic

After unlocking the bootloader during the restart of your device, you see an annoying and nasty warning:

Orange State.

Your device has been unlocked and can't be trusted.

Your device will boot in 5 seconds.

We get rid of it with the firmware of the modified lk.img.

Attention! Install the modified lk.img strictly for your tablet version!

Copy lk-verified-mod.img to the folder with adb drivers, load the device into fastboot mode, enter the command:

fastboot flash lk lk-verified-mod.img

Reboot the device into the system:

fastboot reboot

To restore the original lk in fastboot with the command:

fastboot flash lk lk-verified.img

Sorry guys one quick question I haven't found an answer to yet. Does flashing TWRP actually deletes the tablet's data. I wanted to make a Nandroid Backup, but if flashing TWRP deletes all data there's no point in that 😅
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Just flashing and running TWRP doesn't. But to install a custom ROM, you need to format the data partition and that WILL erase everything. Also, you can't use TWRP to backup data on a stock ROM because the data partition is encrypted. So you need to use some other method of backing up.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ghoppa:
Alright is what I imagined, but didn't know about data partition enctription, too bad. I have been dealing with Samsung devices many years ago and it was all pretty simple and straightforward at that time. Now it's a PITA!

Thank you for your help! :)

I cannot believe I'm asking this because I've had it working properly before.

How do I use stock firmware from Samsung while TWRP is installed. After installing TWRP with the latest official firmware installed, I get the "Android Rescue Party" causing the tablet to keep booting into recovery mode. I can only seem to boot into custom ROMs (GSI and Ultimate).

Thanks for the great work, by the way!

huh do i need to be in android 10 install twrp?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ragarcia87:
For that I would recommend to use the 3.6.0 TWRP that paziusss posted and then follow his guide: https://xdaforums.com/t/guide-sm-t5...flash-lineageos-or-any-other-gsi-rom.4378017/

Thats the easiest way since it has fastboot, or you can use my Skyhawk recovery as well... however simpler to use the 3.6.0 TWRP and then follow his guide :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] craaziik:
i tried and its bootlooping now :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ragarcia87:
You tried what? To follow his guide? His guide is very accurate and works well.. Which Android version is installed on the tablet and which GSI did you try to flash? This will make it easier to help. It shouldn't bootloop unless you tried like Android 10 GSI on Android 11 starting out...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] craaziik:
right now im following step to step the guide but this fastboot resize-logical-partition system 3940000000 what could this be in the 64 gb variant?

hi, im trying to follow step to step this guide but fastboot resize-logical-partition system 3940000000 what could this be in a 64gb variant
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ragarcia87:
I want to assume the system partition is going to be similar so it shouldnt have to be changed.. the only difference would be the userdata or /data partition is bigger in 64GB variant vs 32GB variant...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] craaziik:
so i just put fastboot resize-logical-partition system 3940000000 like it is ?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] craaziik:
and also i try to change the partition size and it just throws me this garbage
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] craaziik:
what can i do abot this?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ragarcia87:
Before running the fastboot commands, you did go to Reboot > Fastboot in TWRP right? or adb reboot fastboot...

What does the output say when you do fastboot devices
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] craaziik:
yup it just restarted and its now a twrp screen saying ¨entered fastboot mode...¨
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ragarcia87:
Ok, and when it says fastboot devices it shows up right? If so then make sure the command is copied exactly right. Because it works when I do it.

You are using too old outdated fastboot... Update your platform tools... my fastboot version is: fastboot version 31.0.3-7562133.. That will explain why you dont have that command avail in your fastboot
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] craaziik:
wait im not using powershell hold on let me try that
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ragarcia87:
I edited my post.. what does it say when you run "fastboot --version"

You just need to update your platform-tools... I uploaded zip of updated version that will have the correct fastboot commands avail :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] craaziik:
wait where can i get a new version of adb?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ragarcia87:
I attached it for easier download on my previous post... lol or you can download from this link:

https://dl.google.com/android/repository/platform-tools_r32.0.0-windows.zip
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] craaziik:
yeah i downloaded the thing and **** and it still bootlooping im so mad
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] craaziik:
can i install it using a usb or something?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ragarcia87:
To install the platform-tools you just unzip it and copy the contents to your adb folder and overwrite... I am sorry your'e mad because its bootlooping... which GSI are you trying to flash? You wanna make sure to use the AB version not just A or A64 the current GSI that I am using right now is: lir-v315-220127-arm64-bgZ-lite.img
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] craaziik:

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ragarcia87:
I am going to download it and see if it works for me or bootloops... I have learned that its also best to flash the GSI kernel that paziusss posted also.. Ill attach it below... Some GSI will reboot randomly and not be functioning except if you flash the GSI kernel...

Attached the kernel below, just flash it in TWRP and reboot and see if it fixes your bootloop issues
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ragarcia87:
I just installed the same GSI that you are having issues with by following the guide posted earlier:

and it booted up... This is with the GSI kernel that makes it so GSI MTP works and also it makes the random reboots stop...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] craaziik:
i tried the kernel it didn't work and is complaining about the security patch level is not supported 😀
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ragarcia87:
Just to be sure, this is the SM-T500 right? Lol... um... so the GSI kernel didnt flash in TWRP, and its bootlooping... what version of bootloader do you have?

fastboot getvar all

Did you start with stock Android 11 SM-T500 or Android 10? I am really at a loss.. cause I Just followed exact directions on guide with the same exact GSI image you are using, and also the same TWRP 3.6.0 to flash the GSI kernel... i would try starting over... fastboot flash product product.img then fastboot erase system then the fastboot resize logical command and just try to do it over again... since you have updated platform-tools now...

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] mystifuzz:
Here's the problem, the GSI kernel won't work on that stock version, you'll have to downgrade to T500XXU3BUJ1 and try to flash that GSI again (and hope for the best!) 😄
