You didn't answer the question. Have you unlocked the bootloader? Has nothing to do with OEM or Dev mode.
[Samsung Galaxy Tab A8 (2021)] HikariWS:
Indeed, I missed the bootloader unlock. I followed https://androidcatch.com/unlock-boo...a8-10-5-2021/#Step_3_Unlocking_the_Bootloader and it worked, green PASS!

But I'm now unable to enter twrp. I hold Vol Up and Power, some lines of white letters show up very quicly, and it seems to reboot. I had tried releasing the buttons and keep holding them and twrp never shows up.

Edit, it didn't work, I'm entering Android recovery mode, with a list of commands: reboot system now, reboot to system load, etc.
[Samsung Galaxy Tab A8 (2021)] lewmur:
Flashing TWRP is tricky. If you allow it to reboot by itself, it will reboot to system instead of TWRP and overwrite what you flashed with stock recovery. Before flashing TWRP click the option button in Odin and uncheck auto-reboot. When it finishes flashing, leave the cable attached, hold vol down and power for about 7 seconds. As soon as the screen blanks, switch your finger for vol dn to vol up while still holding down power. Keep holding both button until red message appears. Release power but continue hold vol up till screen blanks. It should now enter TWRP. Also, after unlocking the bootloader did you let it boot to system and enable Dev mode again?
[Samsung Galaxy Tab A8 (2021)] Zoro53:
Well the touchscreen isnt working :(

does anyone know a solution?
[Samsung Galaxy Tab A8 (2021)] kevinco1:
You have to make sure auto reboot is unchecked.

If you're still not able to pull this off with Odin, you can also install it by using the TWRP app
[Samsung Galaxy Tab A8 (2021)] AverageNoob:
So you can root this device in two ways: Odin or TWRP or any other recovery other than the original one. What about the TWRP file posted in the original post on XDA Forums by @Magendanz? Does it still work for new and recent updates?

Since I have unlocked my bootloader, I am unable to update my Tab. Neither am I using it at the moment. However when the time comes, I can just apply the updates by Samsung's official app (Smart Switch, is that what it's called?), right?
[Samsung Galaxy Tab A8 (2021)] lewmur:
What version of stock ROM are you running? Did you re-enable Dev mode and OEM after unlocking the bootloader?
[Samsung Galaxy Tab A8 (2021)] HikariWS:
Yes, they were enabled. I struggled but got twrp installed, but then I couldn't get LineageOS installed. I ended up giving up and sent to a technician to install. It ended up LineageOS isn't still available/stable for Tab A8 X200 (gta8wifi). So he installed latest stock and removed M$ and some Samsung from it.
[Samsung Galaxy Tab A8 (2021)] kevinco1:
What LOS version/build where you trying to install?
[Samsung Galaxy Tab A8 (2021)] lewmur:
Unless he removed One Ui, then, IMHO, he didn't remove enough. And he can CLAIM no LOS is "stable" but there are several available. I just upgraded to the latest LOS 20 and it is running fine. So is TWRP. Just because he/she is a tech, in no way means they are familiar with installing GSI ROMs.
[Samsung Galaxy Tab A8 (2021)] kevinco1:
Exactly, this is why I was asking for him to be clear about what build of LOS he was having trouble with because besides the light ones every LOS 19 and 20 I've flashed works
[Samsung Galaxy Tab A8 (2021)] HikariWS:
I was trying 19.1 in https://xdaforums.com/t/gsi-12-unofficial-lineageos-19-sm-x200.4495865/

Yes, it's been many years I don't do it. My current phone I left stock and previous to it I stayed years with a custom rom.

Could u suggest a LineageOS build that works on X200? Tecnician also was unable to get one working, he made a discount on original price due to not being able to install it.

Also, what launcher do u suggest? I use ADW on my Android 10 Galaxy Note 9, but it's not updated for years so I preferred to not risk. I didn't wanna use it, but One UI does what I need in having a grid to place icons and it has a TaskBar feeling on its docker.
[Samsung Galaxy Tab A8 (2021)] lewmur:
I am currently using lineage-20.0-20230716-UNOFFICIAL-arm64_bgN.img. It has a task bar in the default launcher.
[Samsung Galaxy Tab A8 (2021)] HikariWS:
Do u know what's its default launcher?

And why are ppl against One UI? Its usability seems better than ADW.
[Samsung Galaxy Tab A8 (2021)] lewmur:
If you want One UI, don't flash any GSI because only Samsung stock has it. I don't use its feature, so to me, it is nothing but bloat.
[Samsung Galaxy Tab A8 (2021)] HikariWS:
I don't want it precisely. My Note 9 has Android 10 so I got outdated. ADW isn't updated anymore so I need a new launcher.

The 2 most popular today didn't fit me, I don't remember their names. I tried One UI that was installed and it has what I need which is grid layout for icons and I liked the new taskbar-like docker. It's better than ADW.

I'm asking why ppl don't like it, the objective reason, and if there's any other launcher with this kind of docker.
[Samsung Galaxy Tab A8 (2021)] kevinco1:
The default launcher is Trebuchet. The taskbar is just an added feature

OneUI is just fine, but it runs terrible on this device since it's lower end which is why most people have flashed GSIs instead

I've used Nova as my main launcher on all my devices for at least the last 5 years
[Samsung Galaxy Tab A8 (2021)] Kreuger:
Hey all. I just got this tablet and after updating, my build is TP1A.220624.014.X200XXS3CWG2. Will this build of TWRP work for me?
[Samsung Galaxy Tab A8 (2021)] kevinco1:
Yes
[Samsung Galaxy Tab A8 (2021)] Kreuger:
Thanks. Could you provide a bit more instruction as to how to do this? Im new to the Odin/Samsung way of doing things. I'm not sure how to "install TWRP to AP with Odin".
[Samsung Galaxy Tab A8 (2021)] MrFluffyOven:
im currently working on a updated version with touchscreen driver included, i may upload later today
[Samsung Galaxy Tab A8 (2021)] MrFluffyOven:
New builds releasing, updated with working touch screen https://xdaforums.com/t/twrp-skyhawk-pitch-black-work-in-progress.4613861/
[Samsung Galaxy Tab A8 (2021)] Kreuger:
So I figured out how to work Odin but it kept failing because I hadnt fully unlocked the bootloader. After doing that, my tablet is stuck at the Samsung Galaxy logo.

Edit: 30 seconds after I posted that, it boots. Go figure.

Edit 2: I now have TWRP. Yay!

Someone help me for decrypting stock firmware I have tried to flashing zip from twrp but it can't boot anymore in to system it's just stuck.
[Samsung Galaxy Tab A8 (2021)] lewmur:
Flashing what zip? And what to you mean "decrypting stock firmware"? You can format data and factory reset wipe to get rid of encryption to then flash the LOS 19 system.img via fastboot. There is no zip file that you can flash with the "Install" button in TWRP.
[Samsung Galaxy Tab A8 (2021)] exebat:
My fastboot doesn't work in twrp idk whay
[Samsung Galaxy Tab A8 (2021)] lewmur:
What does it do? If it says "Entering fastboo....", then it IS working.
[Samsung Galaxy Tab A8 (2021)] exebat:
I have drivers installed but I can't find device
[Samsung Galaxy Tab A8 (2021)] lewmur:
I'm assuming you rebooted into fastboot in TWRP. If your PC still doesn't find the device, the you don't have the correct drivers installed. The very latest driver from Samsung doesn't have fastboot support. You need this version.
[Samsung Galaxy Tab A8 (2021)] exebat:
it dosen't work still

There's some screen shots

View attachment 5981535
[Samsung Galaxy Tab A8 (2021)] lewmur:
I'm sorry but you posts tell me nothing. Saying it doesn't work is pointless. Without knowing what you have done, what ROMs you using, what error message you are getting, what happens when you type "fastboot devices" from your PC, what version of TWRP you have installed. It is like telling your Doctor "I'm sick" and expecting to cure you just from that.

edit: You don't need Power Shell to run fastboot. Just open a CMD and go to the adb dir and type "fastboot devices" and it will tell if it is connected. Also, DO NOT FLASH vbmeta.img. You need to rename your LOS 19 img file to system.img, place it in the adb dir and type "fastboot flash system system.img".

Better but still not enough. One, you need to show that device manager output in English and expand the SM-X200 line to show what driver is installed. The yellow triangle says that is your problem.
[Samsung Galaxy Tab A8 (2021)] exebat:
so sorry about that but my problem is when i install twrp and i wan't to stock rom working but when i format it it wont boot anymore just stuck in samsung logo. i have done this before example whit s7 edge and i know you have to disable encryption but i can't because fastboot dosen't work/show up on my computer i have drives you told me to install but still nothing. dos it have another way doing or i'm missing something?

yes it can't find drivers for that. it's saying that no compatible drivers found
[Samsung Galaxy Tab A8 (2021)] lewmur:
I left you a link to download the version v1-7-48-0 driver. That one works.
[Samsung Galaxy Tab A8 (2021)] exebat:

[Samsung Galaxy Tab A8 (2021)] lewmur:
Make sure the tablet is in fastboot mode and connected to the PC when you install the driver.

I just re-installed them on my PC and it worked just fine. But the Device Manager entry should now read "SAMSUNG Android Phone" and not SM-X200. Did you "Uninstall Device" SM-X200 prior to running Samsung-USB-Driver-v1.7.48.0.exe?
[Samsung Galaxy Tab A8 (2021)] exebat:
i have another computer that has fresh windows installation and there's same problem i noticed that adb works fine
[Samsung Galaxy Tab A8 (2021)] lewmur:
adb uses the same drivers as Odin. NOT the fastboot drivers.

that fastboot driver dosen't work and i can't find reson for it

yes i told i have and if it's not working on fresh installation either.

i have fixed this when i installed other fastboot drivers...

but i need correct vbmeta because after flash it's just boot looping
[Samsung Galaxy Tab A8 (2021)] lewmur:
No you didn't. You have to be doing something wrong when it works for everyone else. Show me your C:\Program Files\Samsung\USB Drivers folder.

NOT ON THIS DEVICE!! If that were true then TWRP wouldn't install. If you installed vbmeta.img, you need to start over and flash stock ROM and then re-flash TWRP. Rather than curing bootloops, on this device flash vbmeta CAUSES bootloops.
[Samsung Galaxy Tab A8 (2021)] exebat:
it's working right now but sure...

View attachment 5981599

what you mean not on this device???? and i have installed twrp trough odin?? and it's working then i format data and flash vbmeta.img torugh fastboot

if i go step by step and you or somebody help me first i flashed stock firmware: View attachment 5981601
[Samsung Galaxy Tab A8 (2021)] lewmur:
I mean EXACTLY what I said. READ THE OP. There is NO MENTION of vbmeta! The steps are flash stock and then TWRP via Odin. Then format data and factory reset wipe, reboot to fastboot and fastoot flash system system.img. NO VBMETA!!!
[Samsung Galaxy Tab A8 (2021)] exebat:
but whay then i can't boot stock firmware whit twrp installed even after i format data and reboot then recovery and then system

but thx for trying help me!!! i jus don't know what to do

if you mean this then i'm correct because i follow instructions View attachment 5981603

i get in twrp this error Android rescue party trigger!
[Samsung Galaxy Tab A8 (2021)] lewmur:
After flashing stock, did you let it boot to system, connect wifi, skip setup and re-enable Dev mode and OEM, before going back to download and flashing TWRP?
[Samsung Galaxy Tab A8 (2021)] exebat:
oh no sorry my mistake

i have done that but still same issue. "The reported problem is: --reason=fs_mgr_mount_all"
[Samsung Galaxy Tab A8 (2021)] lewmur:
What versions of stock and TWRP are you flashing?

edit: When you flashed stock, what CSC did you use? This error appears to have something to do with userdata and flash full CSC instead of HOME should erase userdata.
[Samsung Galaxy Tab A8 (2021)] exebat:
it's not working and i'm using latest that is android 13 and i try flashing full csc but same porblem
[Samsung Galaxy Tab A8 (2021)] lewmur:
The problem is the TWRP version needs to match the stock version. I'm using twrp_3.7.0_12-2_X200XXS1CWA3.tar.md5 which should work with stock CWA3 or later. If that is what you are using and it still isn't working I see no option but to flash stock again and then relock the bootloader, let it reset and start from complete scratch. You know you got it to work once but if you can no longer get into TWRP to format data, that is the only thing I see you can do to get it back to its original state.
[Samsung Galaxy Tab A8 (2021)] exebat:
My twrp is working but that same error is there when I format data? And it's same version twrp
[Samsung Galaxy Tab A8 (2021)] lewmur:
Ignore the error. After formatting data and factory reset wipe, go to file manager and internal storage should only have a TWRP folder. If that's the case, proceed to fastboot.
[Samsung Galaxy Tab A8 (2021)] exebat:
what i do in fastboot
[Samsung Galaxy Tab A8 (2021)] lewmur:
Assuming you have renamed the LOS img file you want to flash to system.img and placed it in the adb folder, then type fastboot flash system system.img

When it finishes type fastboot reboot

custom rom works too i try flash that los20 "system.img" but it's boot looping
[Samsung Galaxy Tab A8 (2021)] lewmur:
Exactly which LOS 20 ROM did you flash? Not just any LOS 20 ROM will work.

edit: The one I'm using can be found on this page. It is the arm64_bgN.img.xz one. I know it works. If you don't want Google stuff, you can try the bvN version. It should also work.

I'm having problems flashing this. Does it work for sm 205 ?

Yeah it works just need wait😅 format memory etc or it's should work if you have correct gsi image?
[Samsung Galaxy Tab A8 (2021)] lewmur:
What version of stock ROM do you have installed?
[Samsung Galaxy Tab A8 (2021)] orestpol:
X205XXU2CWC1 android 13
[Samsung Galaxy Tab A8 (2021)] lewmur:
Then that's not the problem. The OP says this for the X200 but other have stated it works with the X205. I don't have an X205 so I can't verify that. After unlock the bootloader, did you boot system again and re-enable Dev an OEM? Unlocking causes a factory reset and you have to do that again. Other than that, I don't don't know what to tell you. You might want to post a screenshot of your download mode screen. Also, are you using the version of TWRP posted in the OP? And the only option change needed in Odin is to uncheck auto-reboot. No PIT or anything else needed.

Yes I did that after unlock View attachment 5985439View attachment 5985441

The print is too small to read. Take phot of only the print in the top corner.
[Samsung Galaxy Tab A8 (2021)] lewmur:
That's all as it should be, so the problem has to be a mis-match between your ROM and the version of TWRP if you are getting "failed" when you try to flash. Post the entire file name of the TWRP you are putting in the AP slot.
[Samsung Galaxy Tab A8 (2021)] orestpol:
twrp_3.7.0_12-2_X200XXS1CWA3.tar.md5
[Samsung Galaxy Tab A8 (2021)] lewmur:
That's the correct file, so my only conclusion is that is just doesn't work with the X205. Right now someone is working on a new TWRP, Skyhawk, etc. You might have to wait for them to finish.
[Samsung Galaxy Tab A8 (2021)] exebat:
Try skyhawk?
[Samsung Galaxy Tab A8 (2021)] lewmur:
I noticed in that thread that there ARE different versions for the X200 and X205. That tells me the same should be true for TWRP and that the one for the X200 WON'T work on the X205.
[Samsung Galaxy Tab A8 (2021)] Flash1993:
I am getting lost. How do I flash TWRP for the X200XXS3CWG2?
[Samsung Galaxy Tab A8 (2021)] Sunla:
Got the same question. Earlier in the thread, someone said it was fine to flash this TWRP (X200XXS1CWA3) on fw X200XXS3CWG2, but I'm going to have to say that's probably a negative, for obvious reasons.

Now I did patch and repack the file, so it could be my own fault, but upon flashing in patched Odin, the software spontaneously closed, and I had a message in download mode appear saying "final ver." and I think "4.3" but I don't remember.

Stock recovery remained, no other issues.

I'm assuming version mismatch, and you can't rollback versions anymore.

Edit: Went ahead and gave it a another try to rule out a hardware failure disconnect, and to confirm the message that returns in Download mode. I've attached a picture, just in case. I am using patched Odin to flash AP only - TWRP repackaged after patching recovery.img.

Could be anything else, but that's what I'm getting - just seems probable it's because it's a version mismatch.

If a version for X200XXS3CWG2 surfaces, I'll be so stoked! View attachment 5989031
[Samsung Galaxy Tab A8 (2021)] lewmur:
I said it because I did it and it worked. It isn't always the case that an earlier version of TWRP will work with the latest stock ROM, but, in this case, it did.

BTW, I used UNPATCHED Odin and UNPATCHED TWRP 3.7.0.12.
[Samsung Galaxy Tab A8 (2021)] Flash1993:
So do we do TWRP first or Root with Magisk?
[Samsung Galaxy Tab A8 (2021)] Charlie.w:
I have a Samsung Galaxy Tab A8 of this model but they're recovery you provided is not right for my tablet don't get me wrong you worked very hard for it and I respect that but would you mind seeing if you could make one for this x200xxs2cwd2
[Samsung Galaxy Tab A8 (2021)] lewmur:
I'm afraid you are wrong. This TWRP is for the SM-X200 and works with CWD2 firmware. If it isn't installing, then YOU are doing something wrong. Apparently your tablet is for the Brazil region but there aren't different TWRP recoveries for different regions. If you want help, you need to list EVERY step you took and how and when it failed.

BTW, the latest firmware is CWG1, not CWD2. You should flash that before trying TWRP again.
[Samsung Galaxy Tab A8 (2021)] kevinco1:
If you glanced at any of the previous pages of this thread you'll see it's working for everyone. The problem is on your end, retrace your steps

I purchased a Tab A8 recently (via Amazon - US) - it has X200XXU1BVI6 on a SM-X200/gta8wifi. I've been looking about installing TWRP on it and after that lineage - but I don't see a specific TWRP version for my specific instant. Can someone provide some pointers on where I should go from here?
[Samsung Galaxy Tab A8 (2021)] lewmur:
You need to update your stock firmware. Your version is old.
[Samsung Galaxy Tab A8 (2021)] 4romany:
OK...I've updated last night on my Samsung Tab A8 to x200xxs3cwg2.. there is nothing outstanding as far as updates at this point. And I've done a *lot* of reading on these forums - and I'm STILL confused. Which version of TWRP should I use x200xxs3cwg2? I'm assuming that one of the downloads I'm seeing posted by Magendanz is the TWRP image I should use with Odin. And after this process is done I still have to pick out a GSI "rom" or a custom rom at some point. I'm pretty much a newbie on this to a large extent. I was able to get TWRP and LO on a 8 year old Samsung tablet - but this process for the A8 seems to be more involved - or perhaps there are just more choices. Anyway breadcrumbs would be appreciated....
[Samsung Galaxy Tab A8 (2021)] lewmur:
I don't see your problem. Look in post #1 in this thread for the link to the md5 file. That is the latest version.
[Samsung Galaxy Tab A8 (2021)] 4romany:
This file?

It that

I don't see any img files that has x200xxs3cwg as part of it name. On page 1 of this thread I see TWRP for S1CWAS and U1AVE1 but not any that would seem to match mine.
[Samsung Galaxy Tab A8 (2021)] lewmur:
Do you have any idea how many different version numbers there are for X200s? You are NOT going to find an exact match for yours. And it isn't an img file you want anyway. Odin needs the md5 file and the one linked in post #1 is the one you need.

[Samsung Galaxy Tab A8 (2021)] 4romany:
Thanks for posting this howto - it worked perfectly on my Tab A8. I use Arch as my linux distro and never had any issues with my PC recognizing the tablet - it just worked. I knew there were linux apps for this kind of stuff - but there were so little "real world" examples - until you posted this - that I just used a windows VM in VirturalBox to run Odin...
[Samsung Galaxy Tab A8 (2021)] Rosalie241:
I've managed to flash TWRP through Odin fine after unlocking the bootloader, however the touchscreen isn't working for some reason, though it works fine when booted in android, I haven't tried any custom GSI images yet due to being unable to properly use TWRP. so I've attached the /tmp/recovery.log file which will hopefully be somewhat useful.

I'm not sure what's going on though, considering nobody else has reported this issue, it seems like only I have it.

EDIT: I only searched for touchscreen in this thread when writing this post, when searching for touch it seemed like people used to experience the same issue.
