It's now a bricked tablet after a boot loop, I think should wait to magisk get an update. It won't power on or charge I think. I have two days trying to power on in several times and many key conbinations. No Samsung logo or something. Can I do anything to recover the tab?
[Samsung Galaxy Tab A8 (2021)] thicc_pp:
I had bootloop after trying to root my A8 as well. I wasn't able to figure out how to root but you can get out of bootloop by entering download mode by holding down the power and volume down keys for a while.

Odin should recognize that you're in download mode, so you can flash the stock AP at that point. This got me out of bootloop.. It won't be rooted but you'll be able to use it.
[Samsung Galaxy Tab A8 (2021)] arutsuro:
Yes but after some restarts in bootloop it got hard bricked, I can't get download mode since can't turn this on... I don't know what to do, I tried in many ways turn on.
[Samsung Galaxy Tab A8 (2021)] keksas3:
holding down volume up and volume down while it was boot looping got me to download mode. i just nedeed the wright moment to connect the cable while holding those buttons down. in your situation i have no idea what to do...
[Samsung Galaxy Tab A8 (2021)] arutsuro:
After some days I was able to turn the tab on and enter in download mode finally. The battery wasn't seem to be drained I don't know what really happened.
[Samsung Galaxy Tab A8 (2021)] Aelliaria:
Had the same problems, I just gave up after serval trys
[Samsung Galaxy Tab A8 (2021)] arutsuro:
Maybe you could turn your tab on if you leave it some days to rest. After that mine turned on at once.
[Samsung Galaxy Tab A8 (2021)] Aelliaria:
Oow sorry, I meant that I had al the same problems but stopt trying rooting the device haha
[Samsung Galaxy Tab A8 (2021)] garyemiller:
I updated my tablet to X200XXU1AVC1.

Factory reset.

Installed Magisk Manager 24.3

Patched the AP (super.img) file

Used Odin 3.14.1 to flash the patched AP.

I was not fast enough to get to the recovery to factory reset.

That got me a bootloop, then a hard brick.

Several days later, I was able to enter the recovery menu with Vol UP, Vol DN, and connecting the USB.

So, back to flashing my table to X200XXU1AVC1,

Install Magisk

Patched boot.img from the AP file.

Use Odin to flash the boot.img as AP.

Odin was smart enough to download the super.img, add the new boot.img and flash it.

Once again, I was not able to get to recover and factory reset.

Once again, boot loop.

Once again hard brick.

So, any ideas how to root X200XXU1AVC1?
[Samsung Galaxy Tab A8 (2021)] garyemiller:
I updated to Magisk Manager Canary, version 24.3.12. Then, once again:

Patched the AP (super.img) file. I did notice

that Magisk patches both the boot.img and the vbmeta.img in the AP file.

Used Odin 3.14.1 to flash the patched AP.

I was not fast enough to get to the recovery to factory reset. I did PWR and Vol Down for 7 seconds o get out of the bootloader. Released, then PWR and Vol Up, but no luck getting into recovery.

That got me a bootloop for a few minutes that I could not break out of, then a hard brick.

I likely have to wait a day for the battery to drop before I can try anything else.
[Samsung Galaxy Tab A8 (2021)] arutsuro:
If I remember correctly you need to replace the boot.img instead of super.img, then patch it using TWRP.
[Samsung Galaxy Tab A8 (2021)] garyemiller:
As noted above: I tried both naked boot.img patched by Magisk Manager, and super.img as patched by Magisk Manager. Naked boot.img will not work as vbmeta.img also needs to be patched so that boot.img will not be rejected at boot time.

I would love to use TWRP, but, as noted above, there is no TWRP for the SM-X200.

Olá, estou com o mesmo problema que você... Quantos dias de consulta para o tablet dar "Vida" novamente? :(
[Samsung Galaxy Tab A8 (2021)] Tony Ronaldo Matute:
Morning! I have the same issue here with my tab A8, same thing, I replaced the vbmeta by the "clean" Google version to install a GSI room, after several bootloops (and me trying to put the tablet in download mode) the tab just gave me a black screen. And nothing more, I had try a couple of days to boot the tab, with and without PC, but nothing at all not even the download mode, any suggestions or ideas?
[Samsung Galaxy Tab A8 (2021)] Vinpinto:
Same thing happened to me, flashed google's vbmeta and bootlooped out into the wild for one full day, quickly showing "sysdumping now, keep powering on / reset mode:abnormal", just waited until it shut down by itself eventually, then connected to my PC and keep power, volume up and volume down for 4 o 3 boot loops and it eventually went into download mode
[Samsung Galaxy Tab A8 (2021)] UnnA^:
Ugh, i patched the whole AP and now my tab is just black. Cant turn it on/off reset, download mode.....nothing. any ideas? It's been 24hours but still nothing.

Hi,

I have a

Samsung Galaxy Tab A8, Android Tablet, WiFi, 7.040 mAh Akku, 10,5 Zoll TFT Display​

and would like to root it

is there a tutorial available?

thks
[Samsung Galaxy Tab A8 (2021)] asadgsm75:
i root this using this method

download same firmware

extract boot.img from ap file then convert boot.img to boot.img.tar with 7zip

after unlock bootloader patch the file

flash file with bl csc and home

after it reset the tab

rooted
[Samsung Galaxy Tab A8 (2021)] mach87:
i got mine bricked too i just returned everything to stock.

i had to plug usbc to pc open odin and hold vol up and down to return to download mode.

once it actually let me i closed and opened odin again and put the bl, csc home, and the untouched ap and reset it.

i did have to wipe data and factory reset

at least the tablet still works

sm x200

did you get it to work?
[Samsung Galaxy Tab A8 (2021)] UnnA^:
Yes, after 5 days I think the battery finally ran out and I was able to get it into download mode and recover it
[Samsung Galaxy Tab A8 (2021)] Fredcop:
Got stuck in bootloop -> brick as well. Tried opening, pulling the battery and reconnecting it. Still dead. I don't understand why it died.
[Samsung Galaxy Tab A8 (2021)] asadgsm75:
just keep it for 3 days and after it hold both volume butns and insert usb cable you will see the blue screen press volume up and then flash the latest firmware that you able to download from sammobile and after it you can root the tab..
[Samsung Galaxy Tab A8 (2021)] Fredcop:
Thank you for your reply, I will of course try waiting. At the moment I'm more curious why it's dead and then spontaneously resurrects later.
[Samsung Galaxy Tab A8 (2021)] asadgsm75:
just keep it for 3 days and after it hold both volume butns and insert usb cable you will see the blue screen press volume up and then flash the latest firmware that you able to download from sammobile and after it you can root the tab..

its not dead its a bug in this model and its come alive again after 3 days
[Samsung Galaxy Tab A8 (2021)] Fredcop:
Yes absolutely, but shouldn't pulling the battery expedite the process? It's intriguing as to why it happens.
[Samsung Galaxy Tab A8 (2021)] asadgsm75:
i was never try to remove batrry i have my shop i face this problem 2 time but i wait both time
[Samsung Galaxy Tab A8 (2021)] Fredcop:
After some more testing, I managed to reflash it without the screen turning on. It seems as it now actually boots, since it appears in file explorer eventually as a media device (and in device manager as SAMSUNG Mobile USB Composite Device) . Still black screen though.
[Samsung Galaxy Tab A8 (2021)] Fredcop:
One week later, still black screen...
[Samsung Galaxy Tab A8 (2021)] Loki_123:
I just got this issue today. I don't know how long I'll have to wait, but I hope I don't have to wait for very long. I'll wait three days and try to enter bootloader, but if that doesn't work, I'll send it in for a repair.
[Samsung Galaxy Tab A8 (2021)] XenHat:
hello there, another victim of failed rooting AVC1 here!

I've been able to sucessfully root this unit before but I must have done a mishap and lost some notes because I tried to patch the whole AP as some guide instructed, since i couldn't find system.img... then I forgot to remove vbmeta from the archive before flashing...

Bootlooped until it bricked itself while i was getting the clean image ready, and now it won't power on at all.

I'll wait a few days for the battery to drain and try again. I'll report if i manage to unbrick it, any advice in the meantime is welcome :)

p.s. there really needs to be a template how-to-shenanigans for every device thread, pinned, and complete with new-to-android-hacking steps that are valid for that specific model, instead of having to rely on broken 8 years old guides, or 4 half-guides with missing pieces.

my 15 years of c++ and Linux experience aren't really helping me with this, hahaha.
[Samsung Galaxy Tab A8 (2021)] kevinco1:
Rooting works just fine with AVC1

While I applaud you for your 15 years worth of experience with c++ and Linux, none of that applies to the skill set of rooting a Samsung tablet with Magisk.

You mentioned you needed to find system.img to patch and I think that's where you went wrong. It's supposed to be boot.img

Also why try to root A11 when A13 has been out for a while now?
[Samsung Galaxy Tab A8 (2021)] XenHat:
I was trying to revert to an older base for LineageOS and/or Rooting because I've had many storage-related failures on the newer images (app plugins not installing, unable to send pictures in Telegram, etc).

Plus the SM-X200 isn't a very powerful tablet and I don't think it's going to get any faster on newer OS. I'd love to be proven wrong, though.

I've tried booting the tablet one day after leaving it alone, No success. So I left it out for two more days, still nothing.

It'll be close to a week now since I last attempted, I'm pretty sure the battery is flat.

What should I do to at least get it to *power up* since holding the button didn't work last week?
[Samsung Galaxy Tab A8 (2021)] lewmur:
You need to hold both vol up and down and then plug in the USB cable to the PC. This should allow you into download mode to flash from Odin.
[Samsung Galaxy Tab A8 (2021)] XenHat:
You're a life saver!

Now to attempt it again after a full flash.
[Samsung Galaxy Tab A8 (2021)] XenHat:
heimdall didn't quite work, so I had to bring out windows and ODIN but I got it to work again!

I'll attempt rooting again at another time, I'm just happy it's not dead for now.
[Samsung Galaxy Tab A8 (2021)] pvhpobel:
I had the same issue to. I purchased a Chinese SM-X200 tab. I flashed it to my region and then attempted to root it. ( Android 13)

I followed the procedure like on this video:

I used for the rooting:

patched odin : Odin3 v3.14.1_3B_PatcheD

Magisk-v26.1.apk

SM-X200_EUX_X200XXS2CWD2_fac

Unfortunately, I encountered a bootloop issue when I reached around 9 minutes and 42 seconds into the video. Initially, I was in a soft brick state. I reflashed the tabA8 and try rooting it again. However, again at the same point in the video, I got stuck in a bootloop and the SM-X200 was now hard bricked.

So no response when pressing

the power button,

charging,

power and volume up and down buttons, and connecting it via USB cable to pc

I read here that waiting for around 5 days could help resolve the issue, I was sceptical but I could not do much more else than wait. And indeed after 4 days, the SM-X200 tab started working again.

I was able to enter download mode and reflash it once again.

Yet now I'm not sure if I should root or not.
[Samsung Galaxy Tab A8 (2021)] lewmur:
Just curios. Why are you using instructions for the T225 when you have a X200? Not all Samsung tabs have the exact same procedure for rooting. There are instructions for the X200 in this forum. And why the patched Odin? Regular Odin works just fine.
[Samsung Galaxy Tab A8 (2021)] lewmur:
It had been awhile since I rooted the stock ROM, so I wasn't sure it still worked with the latest version. I was running LOS 20 so I couldn't tell what stock version I came from. But so many people seem to be having problem that I started over in order to test what works. So here is what I did that worked.

Assuming that the device has the bootloader unlocked and OEM has been enabled in Dev mode.

1: Download the latest CWD2 ROM using frija.exe

2: Flash it with Odin and let it reboot.

3: Connect wifi but skip the rest of setup.

4: Enable Dev mode and check OEM. It may be greyed out but should still be enabled.

5: Enable USB debugging and set USB to File Transfer.

6: On the PC, use 7-Zip to extract boot.img from AP md5

7: Download Magisk v26.1.apk and copy it and boot.img to the tablet SD card.

8: Install and run Magisk on the tablet and choose the boot.img as the file to modify.

9: Copy the file magisk created from the Internal storage Download folder to the PC.

10: Rename the magisk file to boot.img and use 7-zip to tar it.

11: Boot the tablet to download mode and flash the boot.tar file with Odin in the AP slot.

When the tablet reboots, run Magisk again and you should have root.
[Samsung Galaxy Tab A8 (2021)] JFDee:
Hmm, I did all that, but Magisk does nothing when run in the end; it just says "Installed: N/A" ...

Edit: The firmware that I use is the 'European' (multi-country) version. After installing or resetting I have to choose language and country - then the device reboots once more. Can this be a factor? Does your firmware do the same thing?
[Samsung Galaxy Tab A8 (2021)] JFDee:
OK, I flashed the boot.tar once more. Now Magisk is active ... The only thing I did differently was to switch off auto-reboot in Odin, and to reboot manually after flashing.

Feels a bit like Voodoo ...

Anyway, what does definitley NOT work is Magisk's recommendation to patch the entire AP package.

So just patch and flash the boot.img.
[Samsung Galaxy Tab A8 (2021)] SamDaaEpic:
I flashed Lineage OS GSI on my Tab A8, and in order to make it go to landscape mode in the lock screen i tried changing the /system/build.prop file which could only be changed via root, so I tried running adb as root and disabling adb verity in order to mount /system as rw and modify the build.prop file. But as soon as I rebooted after disabling adb verity my Tab just started bootlooping and it shutdown itself and didn't boot again. Its just a plain black screen not getting detected by odin or any other flashing software, not even the windows device manager. I cant enter download mode, nor the recovery. I can't do nothing.

I've put rubber bands on its power button to keep it pressed in order to make the battery drain for around 2 days but nothing yet(I put it on charged after I bricked it for like 4 or 5 hours, but nothing happened, idk if it charged it or not). Can someone please help me out.
[Samsung Galaxy Tab A8 (2021)] kevinco1:
There's an option in settings to make the lock screen landscape automatically without having to edit build.prop

Do not run any scripts or commands to disable verify, it doesn't work for this device and it'll put you in an endless bootloop

It takes more than just a few days to drain the battery, be patient. Afterwards flash stock again through Odin to get back up and running
[Samsung Galaxy Tab A8 (2021)] SamDaaEpic:
I plugged it on charge after I got it bricked for around 5 hours, Will it have charged the tab. And will it have increased the time it'd take to dry out the battery?
[Samsung Galaxy Tab A8 (2021)] kevinco1:
Do not plug it into an outlet! You need to let it drain completely and that's not gonna happen if you keep on plugging it in, even if it's for a short time

Read what I said again...not 5 hours but a few days
[Samsung Galaxy Tab A8 (2021)] SamDaaEpic:
I think you didn't understand what I said, I Charged up my Tab for 5 Hours Straight, to see it'd turn on the, first time I bricked it.
[Samsung Galaxy Tab A8 (2021)] SamDaaEpic:
Thank you so much for your help! I got my Tab Back up running. I had put it in the drawer for around 4 or 5 days and today it finally booted and I flashed the stock rom on it. Again Thank you so much!
[Samsung Galaxy Tab A8 (2021)] ViolentMob:
Hello, I have a different phone: SM-A035F with the same issue and alsu use Unisoc.

It bootloop with the following message:

sysdumping now, keep power on
reset mode: abnormal mode
no valid adress, no info display
no valid adress, no info display
no valid adress, no info display
wait.... done

And I was unable to enter download-mode. I solved it by waiting until the battery dies before trying to enter download-mode.

Cause: flashing kitsune-patched vbmeta.img + boot.img

Issue: Initially, the device bootloop before going into some sort of dead boot. During the initial bootloop, I can't enter download-mode and recovery-mode. While it was in dead boot, it won't respond to charging and button press. I detach the battery and reattach it again. I then connected it to usb. And it boots up!! But the bootloop persist... I still can't enter download-mode and recovery-mode.

Solution: I wait until the battery dies and then tried to enter download-mode and it works!! While bootlooping, I connect the device to pc using usb and press the vol-up and vol-down button. After a few bootloop, it finally enters download mode!

Extra note: I can't flash the stock vbmeta and boot image on linux using Thor to apply fix. It throws the following error:

Failed to bulk write: Resource temporarily unavailable (11)

Even though I always used it before the bootloop. I believe Samsung device specifically blacklists my pc from flashing on this device. As it has happened on my other phone before (SM-J730G). I can flash on windows though.

I want to install custom ROM but I only have one phone right now, I use this X3 Pro for several apps(mostly banking, internet food services, delivery services) that requires SafetyNet.
[Xiaomi Poco X3 Pro] PhotonIce:
Read the ROM description and look for safety net, if it's not written then just ask if it supports it. If you've still got no luck, backup your stock system (full twrp backup) and then flash the ROM and test if it supports safety net

[Xiaomi Poco X3 Pro] Alec Chan:
All of the rom I tried are passing. If it doesn't just install MagiskHide Props Config. Steps are here. If you are using magisk v23 then enable magisk hide. If you using magiskv24 then enable zygisk, enforce list and choose google play service in the deny list then tick com.android.gms and com.android.gms.unstable. If you can't find it then tick show os app in the menu then reboot. It should pass.
[Xiaomi Poco X3 Pro] gringo80:
this thing doesn't exist

There is this ROM but just didn't post on xda. Idk why dev don't post it but you can search on Google and go to their source forge folder. You can download there.
[Xiaomi Poco X3 Pro] Lu5ck:
rom post in xda need to provide their kernel source code which is something for whatever reason some people find it uncomfortable to do so

Actually, some LOS contributors put together a safetynet fix without the need of magisk, obviously not an official thingy.

SafetyNet seems to pass out of the box with most of the ROM's now, unless you flash Magisk.

But the latest version (Magisk 24.1) with zygisk, has a module available called Universal SafetyNet Fixer (by kdrag0n) which seems to fix both CTS Profile and Basic integrity.

[Android Q&A, Help & Troubleshooting] BereketWAB:
I have a TECNO SPARK GO 2020 (KE5). I waited till its warranty run out to root the device. But I downloaded the factory boot image instead of the current updated one and proceeded to unlock the bootloader. I used these commands in fastboot.

fastboot flashing unlock

fastboot --disable-verity --disable-verification vbmeta vbmeta.img

fastboot flash boot boot.img

This is my first time trying to root a phone so I know nothing about it I just tried to follow instruction here.

After all that I have tried to get the correct boot image file and follow the same steps but it replies with

fastboot: usage: unknown command vbmeta for the second command above

error: cannot load 'boot.img': No such file or directory for the third command
