can anyone help me root my samsung Tab A 10.1 with S Pen ? - Samsung Galaxy Tab A series Questions & Answers

I tried installing TWRP but always failed, the nearest TWRP build I can find is for gtanotexllte, but mine is gtanotexlltedx, so I tried flashing the non dx version (I haven't found the DX one) and It just bricked the tab, any help ?
Edit: My device is the S Pen version (SM-P585Y, Australian ROM, Android Oreo)

You need a DEV to fix TWRP for your device because your TWRP you are using is for Android 6, it needs updating for working on android 8.1. Or if you want Twrp, you can downgrade to android 6 and flash it.

I tried downgrading but it says error bootloader binary 1...

The Twrp is only for android 6 and need a developer to maintain it and fix error with android 8.1. If you want twrp, just downgrade your tablet to android 6 and flash twrp.

Commonly TWRP will not install if you're using a version incompatible with the device, check to make sure. You should always have the original stock frimware on hand in case anything goes wrong. If you do encounter difficulties such as bootloops you can basically start over by flashing in the stock firmware in download mode via Odin3. Sometimes after flashing it may take a while for the device to fully boot up, I've had some take hours.

Nexus 10 does not boot after Update

After attempt at installing software update to Nexus 10 tablet will not boot. Have wiped Cache and even then did a factory reset. Nothing. Google appears and then twirling colorful dots and nothing. For hours just twirling dots., Samsung and Google and Best Buy geeks says nothing they can do. No longer under warranty but very upset since tablet was working great until update. I am not very tech savvy but can anyone help or do I just have a new paperweight? Thanks for any advice.
I have not made any modifications to the tablet.
Just flash the newest factory image. Get it and the instructions to flash it from here:
https://developers.google.com/android/nexus/images
yes flash the newest image
After getting a notification of the latest update I went and rebooted for the update to install but it went to the twrp recovery and nothing happens, is there a way to install the update?

Hi Khaon, I have stock lollipop version 5.1.1 . (LMY47V) and latest twrp version. When upgrading it restarts and goes to recoverys main screen.

as a newbie .I'm not allowed to reference your link !!
I rooted my nexus 10 using xda instructions., installed CWM. All good. I tried backup and recovery and screwed something up in recovery. Got stuck in recovery mode reboot loop. Many gyrations, no fix, so I tried factory reset. Still no fix.
I decided to install a new version of the OS using the Mantaray tar you reference above. UBS connecting and fastboot. All messages look good. Now I have the problem reported in this thread. Stuck with flying balls and no boot. Very interested in any suggestions you may have.

So you keep just boot looping into twrp, right ?
Did you try installing a custom ROM through adb or just connecting your device?
If it keeps boot looping you gotta to wipe the full storage.

No, on a normal reboot or a shutdown/restart it's fine no problems there but when I try to install the update via system update it reboots into twrp. I attach a pic of my system.

Oh I see, well, you should just flash a custom ROM or if you want to stay with official factory images, you should just follow instruction there:
https://developers.google.com/android/nexus/images
What you do need is just have fastboot executable once you are into the bootloader.
You can easily access the bootloader from twrp : shutdown > reboot into booatloader
Cool thx for your continued help :good:
The problem is due to your attempting an OTA update with a custom recovery (TWRP). You can only do OTA with stock recovery. Once you are in this situation, your easiest way out of it is to simply apply the latest factory image using "fastboot", but this will also wipe your user data so backup any photos, music, etc. before you start. You will also have to reload programs from Playstore once the new image is installed.

Wrongly installed TWRP 3.0. 2-0

I was running on an older version of TWRP. Also I had uprooted my phone recently due to battery heating and media server issue. I flashed the new zip file but did not clear cache after flashing instead directly booted into system. System boots perfectly but cannot load recovery as it gets stuck on splash screen( Lenovo logo). Please do help me.
Flash it back to older twrp version using fastboot.
Guys, hi
There is one more new problem. I tried to update the OTA update but got stuck at boot screen. It's not responding after the Lenovo logo. I think the issue is not having any recovery(custom nor stock). How to fix this issue? Please help me to
# Reset stock recovery or TWRP 3.0.2-0
# Update the OTA update( I badly want this as I saw that Resurrection Remix requires the device to presently run on stock Lollipop to update. I soo badly want to use CM13

Thank you. But can you please tell how to do this via the flash boot. I haven't tried yet in a PC. I installed the older TWRP and now tried flashing the new version using my phone. Wouldn't I get stuck because none of the recoveries(custom and stock) are opening
can you boot into the system? if Yes then use rashr app and flash twrp's img file from the storage.. and reboot to recovery and u don't need to update to stock lollipop you can directly flash cm12.1 by ed300 and after booting into system once you can install any lollipop or marshmallow rom with the help of recovery. i advice you to not to do update as u r a root user.

You first hv to root for the installation of recovery.. First root ur phone then install stock recovery.. Using flashify or rashr.
If you can boot into system, then you can use adb sideload to flash zips(recovery or rom).
For detailed info, google it or go to http://www.droidviews.com/sideload-roms-mods-using-adb-sideload/
If it doesn't work, root your phone and then install flashfire. Then use it to flash recovery.

Thanks bro. Is it bad to root using iRoot or KingRoot? Or should I do it using ADB?
@Iamjomy if you have pc then go for adb otherwise go for the latest version of kingoroot.. I rooted with kingroot.. No problem in that.. You can find that apk by searching on google.. !!

Hello,
Thank you soo much. I flashed TWRP 2.8 using Flashify and it works. Actually I wanted to do a factory reset to solve "Unfortunately the process com.android.phone has stopped" issue. It wasn't allowing me to turn on my mobile data. I couldn't reset the phone too as a recovery was missing. Now the issue is fixed and I'm happy with it. Can I flash the TWRP 3.0.2-0 similarly using Flashify? Also please do suggest some good ROMS bro. Im still on the KitKat version( S040_150805)

idk how the problem occured I followed the root instructions perfectly . I had the latest twrp out so couldn't have been that. os was missing and nothing i tried could get it back installed, so following more instructions led me to downgrade the twrp and install b29 stock then i just did the whole root process over following the same instructions that sent the phone into a loop but this time everything worked correctly. i updated twrp and installed super su and now i have full root. axon7toolkit provided majority of the tools needed.

Cannot get TWRP on Oreo, only on Nougat, phone keeps rebooting.

Hi,
I have a S8+, SM-G955F and I cannot have Android Oreo and TWRP (and then root). I only can have Android 7 and TWRP (and then root).
Current situation is: I have Android Oreo, Build G955FXXU1CRB7 is installed. Once I go to Download Mode and flash TWRP, I can boot into TWRP, but my device is not booting into Android anymore. It starts up, shows me the Samsung logo and reboots, then it shows samsung logo again and reboots.
It reboots and reboot and reboots...If I go to TWRP and make a factory reset or format data, it does not help, it only reboots when trying to start Android.
Even if I restore an older backup of boot, systems partition, it does not work...
So what do I do? I flash original Android Oreo firmware once again via Odin and get it back working, but: I loose TWRP again (and cannot flash SuperSU).
Any idea? I would like to have latest Oreo as well as TWRP recovery
Many thanks!

Yes, it was the official one. Just searched the site, but cannot find it anymore. However, flashing the firmware does not need many steps. DOwnload the zip, extract the .tar files in it, open ODIN, load .tar files into Odin and click flash. Then it was flashed and Android was booting again.

you are right, when you flashed the official firmware, on odin did you select the Home_CSC or the CSC ?

I think it was the CSC, but as far as I remember, I also tried the HOME_CSC in the past (not today) but the behaviour was also the same.
As far as I know difference is that with one of these files internal storage is wiped, with the other one it isn't, correct?
But what could this have to do that I get a restart-loop when flashing TWRP? I dont have a problem to flash original firmware, it works. But once I flash TWRP I cannot start Android anymore and have to reflash Android firmware again.

Hi again,
I got an OTA Update this morning, so current build on phone was G955FXXU1CRC7.
I now downloaded the TWRP file you mentioned and followed the guide you mentioned.
TWRP was installed using latest Odin Version 3.13, then I tried to install SuperSU, but this failed, red error messages like failed to mount /data, unable to mount storage.
same for factory reset, does not work. I formated data, it worked. then I installed Super Su, it was possible. then I rebooted device and what shall I say, it booted into Android
Dont know what I did different now, maybe not trying to boot up Android before installing supersu.zip?
However, Now I have latest Oreo with TWRP and phone is rooted
Now I will go on and install xposed framework :good:
Many thanks for your help.

Usually Samsung bootloaders are backwards compatible, so you may still be able to downgrade.
You could also just try using the touch screen binaries from Android 7.

Just flash ap only. Be aware you will also need to factory reset, so make sure you are oem unlocked.

All I can suggest is Install twrp and flash the kernel with that.
However you will need to pull out the boot.img from the AP tar file.
What kernel should i flash and ap? 8.1 o 7?

Basically you need to remove the boot.img from the AP tar archive then install the rest of the AP file without the boot.img using ODIN.
Then install twrp and flash the boot.img.
Format data and reboot.

There's a chance It may soft brick it. However soft bricks are fully recoverable by simply flashing the stock firmware or just restoring a backup.

Depends on the custom rom. If its based on stock dm-verity will need to be disabled. Rooting will accomplish this.
If its based on lineage or other aosp sources then it shouldn't be necessary.
However a format of data will be required either way.

How did you install the rom?
Does touch work in twrp?

touch does not work in twrp
rom installed by twrp
does it means that my touch is really dead if not working in twrp?

Maybe, but it depends on the twrp version you are using.
Try a build based on nougat.
This was one of my early builds before it became official.
