New OTA update - BuIld LMY47X.G928CXXU2A0J5 blocks recovery and root on G928C

Guys I have a G928C model which just received an OTA update of some 150MB. I can confirm that it is a fresh update which came today.
After updating I tried flashing custom recovery following the method mentioned on [HOW TO] Rooting Flashing Custom Recovery & Kernal thread. Odin fails to flash recovery, stock recovery remains. Other two images are of me trying to flash the older stock rom which gives another strange error.
Please help me out.

Did you enable the option oem unlock in developers options?

OEM unlock and usb debugging were on

MD5 of the files were ok? I assume you have the kernel/recovery specifically for your device.

No issues with MD5, kernel or recovery. Was running the device with custom recovery,kernel and root before i went back to stock and updated it OTA.

It is mentioned a few times that J5 is NOT downgradeable, so no chance to go back to you old rom!
and, if i remember right, it also has been mentioned that J5 blocks custom recovery! search in the general section!

To fix the boot loop just re-Flash stock ROM (but no root yet)
Then find & flash custom PERMISSIVE Kernel for your Note 4 type if you are still want to be rooted.

you are facing a locked bootloader as we all are (both exy and snap) the only solution to fix your bootloop is to install apps like phone info then find out what your phone PDA version is then find the exact PDA from Sammobile or if you you are Having an 910C flash latest COJ5 rom or if you are on 910H try installing COJ4 rom (just download and install the latest frimware from sammobile or ... and you will be just fine )

Hi,
I already have a same problem with you, but i can through this..
you just find the right Firmware, its mean the latest firmware, try to download from sammoblie.com and find firmware for N910K picked the latest one. or folow this link : http://www.sammobile.com/firmwares/download/58333/N910KKTU2COJ5_N910KKTC2COJ5_KTC/
after download you just flash via Odin.
goodluck

Please provide me some information regarding your problem:
How did you flash stock ROM?
What is the type of stock ROM that you flash?
Can you enter Download Mode / Odin Mode?

I will try your method but firsr I have a question: If i restart my phone I get a message on my screen that my phone is unlocked and can't be trusted. So that means my bootloader is already unlocked and I don't have to unlock it again? So I only have to flash revolution recovery and find the file in firnware finder?
Is there a instruction how to install revolution recovery and where to find the file...?

TWRP Recovery for Galaxy Tab A SM-T585 LTE (NO SPEN)

Galaxy Tab A SM-T585 LTE 16GB / Android 6 / European Model
Hi all,
I recently bought this tablet and I am trying to find a working custom recovery to install.
The official TWRP from here https://twrp.me/devices/samsunggalaxytaba101lte2016spen.html
does not work. When I flash it, it does not boot to recovery at all. It must have to do something with SPEN because mine does not seem to support it. I have also tried to flash the TWRP from here https://forum.xda-developers.com/ga...overy-official-twrp-gtaxlwifi-galaxy-t3437666 . This time the tablet boots to recovery and everything seems fine but the partition mappings are completely messed up and I cannot flash any zip or access sdcard contents.
Does anybody have any solution ?

Really ? Noone ?

My galaxy Tab A6 SM-T585 with "twrp-3.1.1-0-gtanotexllte.img" should be work but isn't it...
My best chance was with "twrp-3.1.1-0-gtaxlwifi.img" and im not able to boot without ERASE ALL DATA.
I found a lot of threads talking about twrp recovery and i have come to the conclusion:
dm-verify prevent you do that, because kernel was compiled with CONFIG_DM_VERITY so...
bad time for rooting manufacturer ROMs...
The only way is to install custom ROM that allow this option...
This link provide some idea of my conclusion.... may be exists any workarround or reverse engineering to do...
Im a new user and im not capable of post links so.. if you search > dm-verify android on google, you will see page of source code of android and will be any information about dm-verify.

I got 585 LTE model as well and used the 580's twrp version. That works. But know that it currently cannot use encryption of data partition.

So rooting the 585 comes with many downsides?
PoedelPCS did you encountered other problems besides the encryption? Does LTE works?

Hi! Also I have the T585 LTE, and also I tried the 580's version, but nothing, I can't access to recovery mode, and it goes in a bootloop. I don't know why, I know I must to be quick to press volup+power+home IMMEDIATLY after i exit download mode, but nothing, it goes bootloop. I also tried to flash twrp by adb, but it doesn't recognize my device while it is in download mode, actually only Odin does that. if you want, could you help me? I'm newbie to this things, but I know that installing TWRP is not so difficult, but this time I can't install it. Thanks for attenction!
P.S: I followed this tutorial, https://forum.xda-developers.com/galaxy-tab-a/development/recovery-official-twrp-galaxy-tab-10-1-t3473023

Hey Guys,
I am really struggling to find a TWRP image that works on SM-T585 (Non S-Pen, LTE variant).
Any that I try end up with the same outcome - when I boot into recovery I think it boots ok (I can communicate with it over ADB) but the display is scrambled/just vertical lines).
It's not a physical display problem as the display works fine when booting to system.
So far I have tried various versions of the gtaxlwifi twrp, some versions i found on this forum supposedly for the T585 variant, but so far none of them work.
I'm beginning to wonder if I am doing something wrong. Any help is much appreciated.
UPDATE: Others on a different thread have suggested that it might be because TWRP is not compatible with latest samsung firmware/bootloader.
UPDATE 2: Theory confirmed. Waiting on Samsung to release kernel source (hopefully in a few days). See here.

It went pretty smoothly, but after you do this, you won't be able to enable encryption for your user data anymore. You should also backup your data as chances are high you will need to reset everything if you make mistakes.
I had to flash the no-verity-opt-encrypt.zip file after flashing TWRP onto mine.
You can download it from here too:
