Hello this is fixed by installing the driver, but if the driver is installed and the problem exists you need to

1 go to device manager and you will see unknown device sm-x200,205

2.you need to right click update driver--find driver on this computer--select driver from the list of available drivers on this computer--select SAMSUNG driver from the list.

If you don't know the device, you may be asked to select which hardware to install the driver for, select ADB interface from the list of hardware and then select Samsung driver from the list.

Help im stuck, I've had LeafOS installed on my smx200 but wanted to give crDroid a try. On using fastboot to flash crDroid followed by recovery.img I got a security warning screen and although I got it back to download mode subsequent attempts at installing custom gsi have ended in Samsung screen bootloop. I'm not sure what I have done. I can reinstall stock firmware though.

[Samsung Galaxy Tab A8 (2021)] 5dPZ:
Hi there, I followed your guide from Step 1 to 9 (did not need to do last two steps), and I got LineageOS 21 running flawlessly.

Thanks very much for this detailed guide (and the video helped too)!

The TWRP for my device (WK1) is this one (with touchscreen fixed): https://github.com/MrFluffyOven/android_device_samsung_gta8wifi/releases/tag/TWRP-EGL&Vulkan(Test4)

The LineageOS 21 I used is here (the bgN version, the 5th one with most number of downloads): https://sourceforge.net/projects/andyyan-gsi/files/lineage-21-td/

Afterall, the effort is well worth it! The tablet is running super sleek without any bugs and free of all the Samsung bloatwares.
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
Thanks for your support, I'm always happy to help.
[Samsung Galaxy Tab A8 (2021)] DeepReef11:
I see that this is TWRP 2.6. Should I get TWRP 3.7 mentioned in [another post](https://xdaforums.com/t/recovery-unofficial-twrp-3-7-0-for-2021-galaxy-tab-a8-10-5-sm-x200.4488691/)? I didn't try it because there is a build number attached to it.
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
No, it's also the 3.7.1 number listed next, it's our personal build version with Jimi (TWRP version at the top).
[Samsung Galaxy Tab A8 (2021)] DeepReef11:
No, the link in your instruction (first post of this thread) is the 2.6. I've had to go get the 3.7.0 to get it working. I've been able to install los 21 successfully.

Also, the LOS 20 in GSI custom list is actually LOS 21.

Is the flash stock recovery step optional? If I want to get TWRP back, do I just load it back with odin?

Edit: Where is TWRP 3.7.1? Is it worth it over 3.7.0?
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
yes you can do this works only with gsi los other gsi will not run with TWRP as there are not the right drivers and we are working on this with MrFluffyOven
[Samsung Galaxy Tab A8 (2021)] DeepReef11:
EDIT: OH! I see... I thought it was TWRP 2.6 but it really is 3.7.1 ... I'm really sorry for the confusion. I don't know why I wasn't able to flash los 21 with it earlier, possibly my mistake... When I tried to flash TWRP 3.7.0 with los 21 installed, I wasn't able to make it work, but the TWRP 3.7.1 in your instructions works perfectly. Thank you very much!

Message before my edit:

You meant this link?

https://github.com/MrFluffyOven/android_device_samsung_gta8wifi/releases/tag/TWRP-EGL&Vulkan(Test4)

I've tried it, I get binary is invalid. I downloaded the .img file, am I suppose to use the .zip?
[Samsung Galaxy Tab A8 (2021)] DeepReef11:
EDIT: My tablet is currently bricked. Everything was fine until I've stopped using (and charging) my tablet for a little while. I'm currently trying to drain the battery but it doesn't seem to work, I still get to the knox sceen and can't do anything about it.

Alright, here are my personal notes for installing GSI with odin4. Hope this help. Feel free to use it and change it. It is basically the instructions above with more details.

- # Rooting Galaxy Tab A8

- LOS21 is labelled as LOS20 for some reason. For LOS21, here's the link:

sourceforge.net/projects/andyyan-gsi/files/lineage-20-td

- ## Unlock oem

- Go to settings, enable dev by tapping 7 times build number

- Turn off automatic update, allow usb debugging, turn wifi on.

- Enable OEM unlock

- Poweroff

- Press power + vol+ + vol-

- When blue page arrive, long press Vol+ to unlock then press vol+ vol- while it reboots to get back to odin mode

- ## Install TWRP

- Known working version of twrp:

Working for installing los21: twrp 3.7: https://1drv.ms/u/s!AoqocX31ecnXgsRcMikqeFbiESnwZw?e=QNWhub

Current after installing los21 twrp 3.7.1: https://github.com/MrFluffyOven/android_device_samsung_gta8wifi/releases/tag/12.1-V2.6(unofficial)

Note: For some reason, twrp 3.7.1 didn't work for me for flashing los21. Possibly my mistake. So I had to flash 3.7 then flash los then stock recovery then twrp 3.7.1 to make it work. Perhaps not pressing Vol+ immediately on reboot is the culprit.

- Choose tar file, remove .md5 at the end of the file if it is the case (file ends with .tar)

- Using odin4: `odin4 -a /path/to/twrp-x.x.tar`

If using odin gui, simply click ap button and select the twrp file then start.

- Press Vol+ immediately on reboot to get to TWRP

- ## Install GSI

- Tab A8 custom GSI: https://xdaforums.com/t/complete-gsi-list-samsung-galaxy-tab-a8.4619197/ (for some reason, los21 is under los20)

- In TWRP, wipe -> format data -> type yes

- Then go back to main menu -> reboot -> fastboot

- Rename custom GSI file

- From the archive with the standard firmware you need to extract the stock recovery, it is located in the AP archive, it should also be placed in the adb and fastboot folder. (the file looks like this recovery.img). Extract ap file then remove .md5 at the end (so it will end with .tar) then extract recovery.img from its files.

-

- `fastboot flash system los21rename.img`

- Then with the stock recovery extracted earlier:

`fastboot flash recovery recovery.img`

- `fastboot reboot`

- To reinstall twrp, boot in bootloader (vol+ + vol-), then flash twrp 3.7.1: `odin4 -a /path/to/twrp.x.x.tar` and press vol+ immediately on reboot.

- ## Install magisk

- In twrp, go to advanced -> adb sideload

- Sideload magisk apk: `adb sideload magisk.x.apk`

- reboot, open magisk, there should be a prompt asking to install properly

- Select install directly

It was added to the manual in a hurry, and by running a test it didn't work and I urgently needed to fix it. The stable version is now in the manual, please forgive me, I had to final test it.
[Samsung Galaxy Tab A8 (2021)] DeepReef11:
I wasn't able to make a nandroid backup with the (2.6) 3.7.1 twrp, I suppose this is currently normal?
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
Yes this is normal, we are working on it and we hope that in One UI 6 we will be able to fix it, as the vendor section and the encryption principle of the system should be updated.

[Samsung Galaxy Tab A8 (2021)] DeepReef11:
Yeah that's what I've explained, it is labelled as LOS 20 here:

Since we're now able to flash GSIs properly for this device I thought that a comprehensive thread should be created of what's currently available. Please refer to this post for the crucial step that needs to be done in order to boot successfully...

I'm having the same issue as lottez, when I run fastboot to flash a gsi rom the process shows < waiting for any device > and never recognizes the attached tablet. Anyone solved this issue? *edit* I read further and found steps to try, apologies for the repost of this issue.
[Samsung Galaxy Tab A8 (2021)] catsc4n:
What's the point reflashing the stock/standard recovery in the last steps? Why just not continue with TWRP?
[Samsung Galaxy Tab A8 (2021)] lewmur:
TWRP is needed to use fastboot to flash the ROM, but it is not compatible with running it. It causes a bootloop. So you install it to flash the ROM but reflash the stock recovery before booting the new ROM.
[Samsung Galaxy Tab A8 (2021)] catsc4n:
Not true.

I just flashed LinageOS 21 ( 20240317 ) with the latest twrp 3.7.1 and it works fine without any loops.
[Samsung Galaxy Tab A8 (2021)] lewmur:
Then evidently they fix the problem with the latest ROM. It was certain true with earlier versions.
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
Hello dear XDA users, I will resolve your dispute. There is indeed a problem with GSI booting. The problem is that all GSIs except LOS OS use the EGL graphics driver in their firmware, which is not available in TWRP, and the problem is that the firmware with the EGL driver tries to boot, then it makes a request for information about the driver's availability in TWRP, and TWRP replies that it doesn't have the driver, and then the flashed system refuses to continue starting because it didn't get the right tool to start.

To solve this problem we flash the standard recovery because it has the EGL driver we need.
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
Hello dear users, I have updated my instruction, I made even more simple. If you have any questions, feel free to ask them here or contact me personally.

[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
Always happy to help. But what you say is that the PC couldn't detect your device in Fastboot mode, I'm aware of that problem, which is why I added a link to my step-by-step photo instruction in Imgur (that instruction was under the “Fastboot bug fix” spoiler). I will also duplicate it here. Wishing you all a good day.

Flash version before QPR2. Most ROMS currently do not boot QPR2 so you need to flash the release before Android 14 QPR2. The ROMS that boot QPR2 are Rising OS and another called Superior OS(https://github.com/ItsLynix/RisingTreble and https://github.com/ChonDoit/treble_superior_patches/releases/tag/A14-v20240608)

[Samsung Galaxy Tab A8 (2021)] HawkVision:
question , why do we need to install stock recovery ? your point number 6.
[Samsung Galaxy Tab A8 (2021)] monsiu:
rising is a bit laggy and the other is faster. But rising is more optimized for our device while the other is not as we can not rotate our lockscreen.
[Samsung Galaxy Tab A8 (2021)] HawkVision:
Thank You , any link to the Stock recovery ?
[Samsung Galaxy Tab A8 (2021)] monsiu:
i assume you are on samsung tab a8 (x200 gta8wifi) download the full firmware here https://samfw.com/firmware/SM-X200, or if you have it already just extract the AP file and you will see the recovery image file. Here is how to extract the file:

the firmware is in .tar.md5 so rename by removing the md5 and leave the .tar then extract. So it will now be xxxx.tar from xxxx.tar.md5 then use 7zip or whatever you use to extract the files within
[Samsung Galaxy Tab A8 (2021)] HawkVision:
Thank you so much for the help.
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
Good day sir, the problem is that all GSI's load the EGL driver while booting the recovery but there is a LOS OS that loads the EGL driver while booting the OS itself and the problem is that our TWRP doesn't have this driver because it's hard to implement and to answer your question why we do it, to avoid getting bootloop and returning to TWRP with boot error. And to solve this problem we flash the standard recovery because it has the EGL driver we need in it
[Samsung Galaxy Tab A8 (2021)] HawkVision:
Thank you :) I took LOS working fine .
[Samsung Galaxy Tab A8 (2021)] Skolotaie:
Tried with the suggested recoveries. Got system and everything to format

Oem unlock/bootloader unlock done

Tried 5 different gsi's and none boot, also not with the original recovery form the latest for my tablets available firmware (wich i in between reflashed to make sure it's done right)

Sucks

trying out older gsi's also didn't work

Got this REVVL 6 Pro 5G

- Its bricked.

- Says NFC stopped loading, reboots.

- ADB not detecting it.

- Failed installing MT6388 firmware with Smart Phone Flash Tool Windows.

The only idea i had to stop the boot loop:

service call nfc 7

or

svc nfc <enable|disable>

on adb platform tools. But since i cant usb debug, can i send the

commands from an sdcard? What can we do?

I am going to try mtk flash tools tomorrow with this ghetto ROM and no scatter file.
[General Questions and Answers] NinjaAdmin:
Use mtkclient in Brom Mode. You enter brom mode, when the power is off, plug in the USB data transfer cable (attached to PC) while holding volume down and power at the same time. You can enter during a bootloop if you time it right. I don't know if it will work without the debug mode turned on or oem unlock turned on but it might be your only chance. You have to enter brom mode over and over for each mtkclient command.

Use these commands;

For Dumpload and Backup:

python mtk rl <path to backup folder>

For Firmware Install (should fix brick and bootloop):

python mtk Wl <path to firmware folder>

Should ask for FDR after.

Enter recovery mode at the picture of the Android with its belly open by pressing volume up and power at the same time. Get to there by pressing volumes down and power as the device boots up. In recovery mode you can FDR perhaps without flashing the firmware and fix your issue.
