Well, so does .7.0_12-2_ on mine and others.
[Samsung Galaxy Tab A8 (2021)] MrFluffyOven:
The latest version is incomplete, I started that project as a noob but I'm learning bit by bit to build twrp, it will eventually be finished, but my previous releases have been too ambitious, I suggest you use magendanz version till I perfect my version
[Samsung Galaxy Tab A8 (2021)] Magendanz:
This is just patching the fstab to remove forced encryption, something Mutlidisabler should already be doing.

And this is just how you flash the vbmeta.img on a device with fastboot support, but Samsung uses Download Mode and Odin...and that at least seems to be functioning. I could update the fstab in TWRP so that you could more easily flash the four AVB partitions (vbmeta, vbmeta_system, vbmeta_vendor, and vbmeta_bak) from recovery, but it's not a common thing to do unless you're trying to find a workaround for a bootloader that won't let you disable AVB with a blank vbmeta.img.

Note that fastboot is for flashing physical partitions from the bootloader while fastbootd is for flashing dynamic partitions (in super.img) in userspace.
[Samsung Galaxy Tab A8 (2021)] Magendanz:
BTW, there's a nice little tutorial on using fastbootd to flash dynamic partitions here.
[Samsung Galaxy Tab A8 (2021)] bighit101:
Arrrrr lol

I used odin to flash twrp via Odin and then got into twrp. But now, I have tried installing the above TWRP.img file, it says successful but when I restart out of TWRP it just goes back to TWRP.

What am I missing guys? I dont have magisk.img either becasue I did not make it before flashing TWRP.

Any help will be greatly appreciated!
[Samsung Galaxy Tab A8 (2021)] WackyHacky1:
when will the file manager in twrp work for this device? so far it says 0mb
[Samsung Galaxy Tab A8 (2021)] Tony Ronaldo Matute:
I think that you have to wipe data before use it
[Samsung Galaxy Tab A8 (2021)] WackyHacky1:
ah okay thanks it works
[Samsung Galaxy Tab A8 (2021)] WackyHacky1:
my only issue is once i connect my tablet i cant transfer files even tho it shows the storage is above 0mb

and when i flash a zip i get issues like system_root block device required
[Samsung Galaxy Tab A8 (2021)] Tony Ronaldo Matute:
one of the bugs is the MTP until you desactive it and active it again, did you already try it?
[Samsung Galaxy Tab A8 (2021)] Ollibolli85:
Hello everybody,

many thanks for this TWRP!

It is not permanent, right?
[Samsung Galaxy Tab A8 (2021)] Tony Ronaldo Matute:
It is! You can restart and everything. If you install the stock firmware with Odin, you'll loose TWRP, but is normal
[Samsung Galaxy Tab A8 (2021)] Ollibolli85:
Hmm, i still lose it after turn off the device, even from TWRP-menu...
[Samsung Galaxy Tab A8 (2021)] Tony Ronaldo Matute:
how did you install it?
[Samsung Galaxy Tab A8 (2021)] Ollibolli85:
This way:

Unlock bootloader

Hold Vol Up & Vol Down buttons during restart to enter Download mode

Install TWRP to AP with Odin

Hold Power & Vol Up buttons during restart to enter TWRP recovery
[Samsung Galaxy Tab A8 (2021)] Tony Ronaldo Matute:
what if you root the tablet and install it with the TWRP app? being honest it shouldn't be deleted, even if you install it with Odin lol
[Samsung Galaxy Tab A8 (2021)] Ollibolli85:
"Note that you should just patch the boot.img file and not the whole AP tarball, since this device's bootloader doesn't like the empty vbmeta.img that Magisk will provide."

How to flash the single boot.img with Odin?
[Samsung Galaxy Tab A8 (2021)] Tony Ronaldo Matute:
so, you'll need 7-zip and a PC.

1. Uncompress the "boot.img" image from the AP archive (you can find your firmware at samfirm).

2. Patch it with magisk.

3. Compress it with 7-zip in .tar

4. Flash the image in the "AP" section with Odin.

5. It will be it:)
[Samsung Galaxy Tab A8 (2021)] Ollibolli85:
Hmm, still not work for me...

It's not the first device i mod this way!

Can there be an issue with the latest Firmware X200XXU1AVG1?
[Samsung Galaxy Tab A8 (2021)] Tony Ronaldo Matute:
It's weird cause' my tab has the same version and it keeps the recovery. In fact, my CSC version is TPA, I don't know if it has something important lol
[Samsung Galaxy Tab A8 (2021)] Ollibolli85:
Yes, you use "PANAMA (TPA)", i need "EUROPE (EUX)"!

Now i try the penultimate Firmware-version X200XXU1AVC1...

By the way: Is there a big difference between flashing the whole AP tarball or just the single boot.img?
[Samsung Galaxy Tab A8 (2021)] Tony Ronaldo Matute:
No, but you'll save time if you just flash the boot.img, but if you'll downgrade your firmware version you better flash all the firmware slots.
[Samsung Galaxy Tab A8 (2021)] ZorgonPeterson:
Hi. I'm experiencing the exact same issue you seemed to be having with the version of TWRP from this thread. I can flash it without issue, but touchscreen functions don't work so it's essentially useless.

I tried using the version you've linked there, but as stated in the release notes fastboot doesn't function properly. Where you ever able to find any alternative solutions to this issue?
[Samsung Galaxy Tab A8 (2021)] Rosalie241:
I've looked at the code from the github link in OP and after merging the recent PR, it's kinda broken.

so I decided to fork the repo and try to improve it in my own way, you can download my forked version here, though do note it's only meant for X200XXS3CWG2 and has only been tested on my own device, touch works, fastboot works, and you can flash system images through TWRP itself, which also works, also note that it's still experimental but it's worth trying.
[Samsung Galaxy Tab A8 (2021)] lewmur:
I hope I've made a mistake 'cause I've run into a major problem. I updated my tablet to G2 and flashed your recovery. It booted fine and looks good. So I booted back to system to check for bootloop and system booted OK. But when I tried to boot back to TWRP it booted stock recovery. So I decided that rather than boot to system after flashing your recovery, I'd go ahead and try to flash LOS 20. So I formatted data and factory wiped and installed the LOS 20 system.img. It appeared to flash OK but when I tried to boot it I got the bootloop where instead of the LOS logo screen I got the stock Samsung and then the shutdown and reboot loop. So I started over and this time tried to flash LOS via fastboot and it won't flash. File not found error. Seems like Samsung has fouled things up again with G2.
[Samsung Galaxy Tab A8 (2021)] Flash1993:
Got it. I rooted my Tab with a patched Magisk boot image and then flashed your TWRP image in the Official TWRP app.
[Samsung Galaxy Tab A8 (2021)] torben5247:
I am about to flash los 20 gsi image, but i am a little bit unsecure what recovery thats working. tablet is updated to latest stock cwg2.

Will the twrp linked to in post 1 be the right one to use or should i use skyhawk or pitch black or orangefox?? thanks for any reply
[Samsung Galaxy Tab A8 (2021)] Flash1993:
You could try it. The only thing I would say to do is download the Official TWRP app from the playstore and flash it that way. Then try booting into recovery to confirm. I tried the one Rosalie241 posted above and it worked for me but I didn't try this method on OPs image.
[Samsung Galaxy Tab A8 (2021)] AdarshB:
Hi there!

Can you give a step by step guide on flashing TWRP and installing Magisk? I'm currently also on the G2 version and I'm very hesitant on unlocking the bootloader and installing TWRP.

Thanks in advance.
[Samsung Galaxy Tab A8 (2021)] Baconator724:
I've been struggling with this for a couple of days, every time I flash TWRP my tablet will only boot into recovery.

After flashing the stock AP, BL and CSC I can boot into the stock ROM. If I flash the TWRP tar file as AP it doesn't go pas the boot screen, and reboots into TWRP every time I try to boot the system. What am I doing wrong? I'm using firmware version X200XXS3CWG2 and TWRP version 3.7.0 for firmware X200XXS1CWA3.
[Samsung Galaxy Tab A8 (2021)] tanovicd123:
Hello! I need to know does this work on the Galaxy Tab A8(X-205)? There is a thread but i dont know how to build an img file :(
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
sir, you are a genius for creating a test recovery, I decided to take it for tests under Sm-X205 and the latest firmware version X205XXS3CWG1 Xev region and it worked as it should without any reboots.
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
And I have a question for you: can you fix the data section so that it works and does not encrypted
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
sir, I installed TWRP on our device by downloading a test recovery from Github and selected the Tar archive and uploaded it through the ODIn AP section and rebooted by entering it by pressing the power button and volume up
[Samsung Galaxy Tab A8 (2021)] tanovicd123:
Yes, i know how to do that. But does everything work? Thats what i needed to know.
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
'm also new to firmware, but I really like this topic. Here are the problems that can await you: 1. problem with the DATA partition, inability to format the system partition and inability to install custom firmware region XEV(SM-X205)
[Samsung Galaxy Tab A8 (2021)] lewmur:
You aren't supposed to format the system partition. ONLY the data partition needs formating. Then you factory reset WIPE, which only partially erases other partitions.
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
so how can I reset the settings without logging in?

and I tried to write the system to the Super partition with a file with the extension .img
[Samsung Galaxy Tab A8 (2021)] lewmur:
A factory reset from stock recovery or /Wipe and swipe in TWRP will reset settings. Super and System ARE NOT the same. You can't flash a system.img to Super. That is why you need to use fastboot.
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
but I tried through fastboot and CMD gave me an error
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
I basically can’t clear the system partitionView attachment 6009083
[Samsung Galaxy Tab A8 (2021)] lewmur:
This is only a guess, but it would appear fastboot is not finding the system.img file. Try specifying its path "fastboot flash system c:\platform-tools\system.img". I can't read the name of your C: drive but if there is a character in it the fastboot can't read, that may be the problem.
[Samsung Galaxy Tab A8 (2021)] lewmur:
You don't need to. You don't need /Wipe/Advance Wipe. Just /Wipe and the swipe the bar at the bottom.
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
вот полный путь C:\platform-tools View attachment 6009089
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
It turns out that for everything to work I need to 1. clear the data 2. go to wipe without selecting anything there and swipe from below 3. go to fastboot and flash the file
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
as you said the command fastboot flash system C:\platform-tools\s.img but it did not help meView attachment 6009097
[Samsung Galaxy Tab A8 (2021)] lewmur:
Don't know what you mean by "Clear the data". When you select /Wipe in TWRP, there is the option to Format Data. You do that first and then go back to that same screen and swipe the bar at the bottom. And before going to fastboot, I'd advise renaming your C: drive to something simple in plain English so as not to confuse fastboot.
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
(I would suggest renaming your C: drive to something simple in plain English so as not to confuse fastboot.) I don’t know what you mean by that as it is the C drive is what it is
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:

[Samsung Galaxy Tab A8 (2021)] lewmur:

or maybe I stupidly threw TWRP from SM-x200 into it and I have sm-X205 and that’s why it doesn’t work
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
I answered my own question: to install custom firmware I need to wait until a person develops TWRP standards
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:

[Samsung Galaxy Tab A8 (2021)] kanapka90:
Would TWRP from an x200 device work on x205?
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
yes it will, but you won’t install GSI through it, you can install ROOT in it
[Samsung Galaxy Tab A8 (2021)] kanapka90:
if the device has an operator lock and I want to get rid of it, I have to upload another software or root it and remove the application responsible for the lock, but I have no way to do it, so I need TWRP and would it work?
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
see TWRP works regardless of operator blocking and it will work (TWRP)
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
your problem is that you use 1 operator and cannot use others

if you want, you can write me a private message via telegram https://t.me/MaxiTrusov to resolve your issue
[Samsung Galaxy Tab A8 (2021)] kanapka90:
I have no way to contact you on Telegram, so I will describe it here and I sincerely apologize. it's about this lock, the device was purchased online with an operator lock and I wanted to upload a custom ROM so that there would be no message, the tablet is only to be used for YouTube and I do not intend to connect a SIM card. And my question is whether it is possible to remove this lock from the TWRP point with some custom rom or root if TWRP is for an x200 device and the purchased one is an x205?
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
yes TWRP will work from sm-x200. but I will suggest you to flash the stock firmware from another region and I think your problem will be solved.
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
could you send a screenshot here so I can see what this blocking looks like?
[Samsung Galaxy Tab A8 (2021)] kanapka90:
thanks for your help, but I think I expressed myself incorrectly, because the device I have is x205
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
Sorry, this translator writes via () I will repeat to you this TWRP fits sm-x205 (but custom firmware cannot be installed)

[Samsung Galaxy Tab A8 (2021)] lewmur:
Don't take my word for this, but from what I read, I think it needs to be flash to system_ext_a. There are 2 parts system_ext_a and system_ext_b.
[Samsung Galaxy Tab A8 (2021)] Vinpinto:
Probably I didn't fully explained myself, what I meant is direct system image flashing from sdcard or internal memory into those partitions, without using fastboot, not flashing TWRP into those partitions
[Samsung Galaxy Tab A8 (2021)] lewmur:
I know I have used versions of TWRP that allowed "Install" button to do that, so there must be a way. But you would need someone like @Magendanz to tell you how. Above my skill level. :unsure:
[Samsung Galaxy Tab A8 (2021)] Magendanz:
Yes, you can do this via an OTA update (.zip) file using an Edify script. Documentation is here. Alternatively, you can replace the update-binary file with a shell script, which is how more advanced packages like OpenGApps do it. I recommend that you just open a few up and take a look.

Note that these packages need to be signed if you're going to install them using the OEM recovery. Otherwise, you'll need to install with TWRP.
[Samsung Galaxy Tab A8 (2021)] torben5247:
Hi Rosalie241. I have flashed your twrp today but i cant flash gsi image using fastboot. I just read that you have written: "you can flash system images through twrp itself" what do you mean? do you mean that i can install system.img as a system image in twrp?

or can i install the zip file as system? i hope you can clarify this becaus e it is driving me crazy that it should be so difficult to flash los on this tablet.;):cowboy: Thanks in advance
[Samsung Galaxy Tab A8 (2021)] Magendanz:
Both. If you have an OTA update and the author of that script knows the technique, it can install the images. If you want to install the images manually, you can do that in TWRP too. Since this devices uses dynamic partitioning, though, you've got to use TWRP's Fastboot mode.
[Samsung Galaxy Tab A8 (2021)] tschertel:
Hi guys. Thanks for the TWRP!!

Is there a way to disable the warning messages, like "press power to continue" and "unsecure device" during boot??
[Samsung Galaxy Tab A8 (2021)] torben5247:
so is it that simple.

from stock cwg2

unlock bootloader

usb debugging on.

flash your twrp in odin.

boot into twrp

wipe partitions.

flash system.img in twrp. (Not using fastboot flash directly in Twrp)

and thats it

Not unless you're able to rewrite the bootloader.

Hey @Magendanz, could you add more details about the DATA partition formatting requirement in the initial post? I think it could make things clearer. Just my two cents. ;)

I kind of have a problem.... I had to reflash the stock ROM. But I'd like to know when is the better time to install TWRP. Do I need to configure all Android and just then install TWRP, format DATA end reconfigure everything? Can I flash TWRP before first Android boot?

EDIT: I flashed stock ROM, made the initial Android configuration, Installed TWRP, formatted DATA partition, now I can't go back to Android. The tablet always goes back to TWRP. I did a factory reset in TWRP, without luck.

What can I do now? Do I need to reflash the stock ROM?
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
hello sir, I will help you answer this question 1. yes, you can flash twrp, immediately after flashing the stock ROM, by also going into odin mode, BUT IF YOU DO THIS, YOUR INTERNAL MEMORY WILL NOT BE CORRECTLY ALLOCATED and WILL SHOW 8 GB 2. why you are returned to twrp after clearing the data. This happens because after clearing or formatting the data partition, the system is automatically deleted. but why this happens I can’t give an answer

I hope my answers helped you
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
and yes, if you cleared the data partition and it boots you into twrp, then you need to install the stock firmware since you don’t have a system. you can check this easily. if before cleaning you have errors in mounting the data partition, and when you go to the install item and the internal memory is written 0 mb, then the system is there if after formatting the data partition. you write 50+ gb then you don’t have a system and this is necessary
[Samsung Galaxy Tab A8 (2021)] tschertel:
Hi Maxim. Thanks for your reply.

I'm stuck in this "boot loop" and the only way I've found to get back to Android is reinstalling the stock ROM. But then I loose TWRP. :cry: :p
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
yes but what is the problem when you flash twrp it does not format the data partition. you will have twrp and a stock system but the encrypted data section is nothing more
[Samsung Galaxy Tab A8 (2021)] Maxim-Root:
You can install root without formatting data
