Device Root Key error

Hello family; you all much appreciated for the support here:
i have an G925A stuck in a boot loop and asks to check DRK. i seem to have no clue on how to go about it, and asking for your kind help.
I have the same problem.
I have updated from 5.0.2 to 6.0.1 (I tried different firmwares found here) and now the phone doesn't boot anymore (it says something about DRK) and goes automatically into recovery mode.
Download mode still working but I don't know what to flash anymore....I can't downgrade to 5.0.2 since the bootloader doesn't allow and I can't try to upgrade to Nougat since "install zip from adb" in original recovery doesn't work...

I had the same issue after trying MM ROM from 5.1.1. Finally I solved this issue following step.
1) My trial MM ROM is PK5 version
2) I try Download ROM (full 4 files) via Odin
3) The issue is remained. I try Download ROM via Odin which is 5.1.1 root version in development board. In recovery mode, you can select reboot. Then phone is freezed with galaxy logo screen without entering recovery mode again.
4) I retry Download PK5 AP ROM only via Odin.
Then phone start to work normally with MM.
But it is not fixed issue. If you enter recovery mode. You will meet the DRK error again.
Anyway, I hope you can slove DRK error issue

ran unlock_N4 Verizon Bootloader Unlocker on my t Mobile Note 4

now my phone lags freezes crashes reboots and does random weird s*** all the time I figured out that the files that came out on the SD card when I ran the script are from /firmware-modem/image. My phone is a mess HELLLLL LP
A folder named image came out on the SD card when I ran the unlock_N4 file. When I reflash stock Odin firmware it gave me an error message device does not have drk please indlstall drk and press any button and DMVerity verification failed when it went into recovery afterwards. The serial number is off also. Anybody know how to use fastboot with ADB to flash all the files back in????
did you try Kies?

1st why you ran Verizon bootloader to this phone? this phone has unlocked bootloader it doesnt need to be unlocked
2nd your phone partition got messed up you have to put TWRP back and then go in wipe and then you have to do file repair
3rd when you fix file then ran back the stock firmware which will fix bootloader
then go back install twrp and install custom rom with root, remember 910t, 910t3 comes with unlocked bootloaders no need to unlock them

Note 5 N920G Stuck at Samsung logo

I'm in a weird situation, I flashed the latest stock firmware for my phone (N920GDDS4CRD2_N920GODD3CQJ2_N920GUBU4CRA1_HOME.tar) through odin and now it is stuck. Then I went to download mode again to flash twrp just to try to wipe cache and stuff to get it working, no luck as it wouldn't boot into recovery. Then I tried flashing the same firmware through odin again but I get an error (sw rev. check failed), I know why I am getting this. its because the phone doesn't allow downgrading and the firmware that I am trying to flash is the latest one. Any help would be appreciated.
Check last twrp installed. Next try flash any custom rom.zip

SAMSUNG NOTE 8 N950F (XSP - Singapore Region) WONT BOOT INTO SYSTEM!! HELP!!

hi guys, im lost and desperate need help right now
its been 4 days im looking for solution but no avail
please i need help to make my device back to normal again
device : Samsung Note 8 (XSP - Singapore Region) running One UI 1, Android 9. oem unlocked.
so here is the stories,
3 days ago, 22 Dec 2020.
i did factory reset on my device, and reboot
after that, my device lost the network, it detect my sim card but cant connect to network. signal lost.
i tried to reboot like usuall but still, no network available. lost the signal
but i can connect to wifi.
and i reboot it again, suddenly stuck at samsung logo
at first i thought this is easy just need to flash it with stock firmware
and i did, i download the stock firmware from sammobile, XSP - Singapore region.
with BL, CP, CSC, AP file, repartition not ticked. only tick the Auto Reboot and F. Reset time.
i choose the CSC file not HOME_CSC. so everything went well. PASS! green light in odin.
successfully flash my device, but weird, it is still wont detect any network or signal. i tried to automatically find network operator but it says "unable to connect" i tried everything and it says "NO NETWORK"
i did checked my imei , and its safe, its not blocked. but why my device still wont detect my sim card
and the i tried to reflash and flash and flash it again, several time hoping it will detect any network from my sim card after flashing but no avail
and then at the night, flash at 6th time, my device giving me more problem.
suddenly stuck at samsung logo bootloop. i went to recovery state, its says :
"E: FAILED TO MOUNT /EFS (INVALID ARGUMENT)
DM VERITY ERROR" stuff like that
damnn what problem again this time
im frustated already
and i flash it again with Pixel Experience rom hoping the problem will went away, but still , same results. "NO NETWORK"
i look it up in Settings - About - Status - Sim Card Status , its shown "DISCONNECTED"
my imei still there but just wont connect to network.
and then i tried to re-flash it again with stock firmware and again went straight into bootloop. with broken efs etc some****
im so mad and frustated, the problem keeps coming.
and then i found a temporary solution from @bluecub1st thread about the same problem :
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
The following is a guide for repairing failed to mount efs and dm-verify fail (drk error)
We finally did it ~~~
Warning - We will not take any responsibility for your device. Follow the steps at your own risk. If your device is Knox 0, This guide would convert it into Knox 1 due to TWRP. For solutions that does not convert to knox 1 check out payed remote solutions. Everything on your device will be reset, including efs partition. You will need backup of efs.
Test on N950F binary 4 may work on other exynos models comment below if it worked for other samsung devices.
Problem Detail -
Bootloop with samsung stock firmware boot logo.
Recovery error E:Failed to mount /efs (Invalid argument) or dm-verity verification failed...
Device cannot boot into Factory binary or Stock Rom
Actions that could cause this problem -
Flashing a non-signed efs.img by odin
Corrupt flash of efs partition.
Note - Must have efs backup for device to work (very important)
Any error that cause bootloop would show in recovery required if
Files Required
Latest Odin (recommend 3.13)
Working Stock firmware and Combination file (same binary as bootloader)
PC
Winrar or 7zip etc
Solution for efs failed bootloop-
Extract Stock firmware AP file (rename .md5 to .tar)
Rename dqmdbg.img to efs.img (or smallest image must be smaller than 8000 KB). Extract Dqmdbg.img.lz4 so it’s just “Dqmdbg.img” and then rename it to efs.img and put that one in a tar. Other option is downloading a file that’s already made this way if your bootloader is binary 4, Saves you trouble of extracting / renaming: http://www.mediafire.com/file/589wucja9rk2v8f/efs.tar/file (if you download this file just move onto number 3)
Add file new efs.img into tar archive.
Flash tar as AP file in odin + download mode
Reboot download mode
Flash Combination with odin + nand erase option on Edit: suggest you to flash stock rom first and oem unlock, don't need to wait for 7 days if imei is 0000 skip combination step
Device Should boot into Factory binary
Use IME to restore imei using *#06# (or imei 0000 in stock rom) Edit: This step is not required if efs backup is restored successful
Your device should have dm-verify failed in recovery due to drk error
Continue drk bypass for dm verify error below to continue
Solution for dm-verify error (also known as drk bypass - but temporary read note)-
Extract Stock firmware AP file
Make a copy of boot.img and delete recovery.img
Note - if files is boot.img.lz4 format change name to recovery.img.lz4
Rename boot.img copy to recovery.img
Add all the files (including other files extracted) to tar.
Flash Modded AP file with BL, CP, CSC (nand erase not required)
The phone will boot into stock firmware
Note- cannot reboot, will stuck at dm-verify error again and need to flash modded AP again.
Wait 7 days to oem unlock phone or use 7 day bypass by changing dates (not always work, keep trying, don’t reboot, worked for Samsunguser932 Edit: Imei must be 0000)
Edit: oem unlock will fix drk - if not you must follow next step
Once oem unlock flash TWRP and restore efs backup Edit: if you haven't fixed imei fix now by *#06# with combination file
Flash stock firmware once again by odin (stock, not modded)
Done - phone is back to normal
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
but at my case , the solution still failed,
yes it did success boot back into the system but still my network is still missing.
and he says restore with efs backup but he didnt attach the file to download the efs backup, how can i continue that step?
so i skip that step and just went to reflash it with stock firmware and the problem came again, it stuck in bootloop.
with efs broken ,
anyone here can share your efs backup ?
please i need it
im using samsung note 8 n950f XSP Singapore region
will appreciate your help a lot. thanks a lot

If you can not into download mode and have an unlocked bootloader, you can flash stock Samsung firmware with Odin.
