dm-verity verification failed

2 days ago i flashed twrp on my pure stock note 4, i did backup my rom including EFS using twrp and then flash kyubi rom with nameless kernel, it all went well. just now i wipe data ,system, cache on twrp and restore my backup stock rom and it went well too...and then i try to flash stock rom using odin so i can get back the stock recovery mode for OTA update when MM releases.. the flashing was a sucess and phone booted but my data inside werent wipe.
so i went to recovery mode and saw this dm-verity verification failed on the bottom i proceed to wipe data and reboot my phone, its all working now no problems except i cant reset my phone with the setting inside it will just bring me to recovey mode and stay there with that message.
now i did some research, some saying will bootloop and stuffs but mine is all ok no problem except i cant reset it inside the settings..
anyone can help me get rid of that message/problem?
If you format everything in advance format in twrp and then flash stock firmware this message will go away.
got the same problem. Then I went to a local store. They helped me. Here are steps
1. Pull out your battery, check your serial number (S/N:....)
2. Download smart switch, enter emergency software recovery..... Enter your serial number
3. Turn off your phone. Enter download mode or sth ( I don't remember it clearly. just power + vol down or up. just try it)
4. Smart switch will recognize your phone. Choose a firmware to download. then wait
5. Enjoy stock firmware
Use kies3 reinstall drivers, then use emergency recovery in kies to reinstall your current firmware or opt to update to latest or most recent release or version then follow kies instructions

Hello everyone
I have found a way to fix dm-verity and DRK issues and it works like official, meaning no errors in stock recovery and OTA works with Official firmware, the problem is related to corrupted/deleted 3 files on /efs partition. I have tested it on SM-N910C so I guess it works on other Exynos variants, perhaps even on snapdragon if the partition layout is similar? Kies won't restore DRK or dm-verity check because it doesn't write to EFS. I can fix yours if someone is interested via Team Viewer, you will need the following:
1. PM contact me for Skype ID
2. Stock rom, rooted (any root method)
3. Adb debugging enabled and drivers installed (Kies or SmartSwitch)
After repair you can enter your stock recovery and confirm there is no DRK/dm-verity red letters error.

Mine still says fail. but it also says "need to check drk first" could anyone possibly help me im stuck.the phone loads up and everything. but when i try to root or anything or flash any other firmware than n910pvpu5dqi5 it fails about 4 seconds in to flashing on odin. ive downloaded every possible firmware specific to the SM-N910P but only one worked.
im a big noob with the note 4 this is my first luckily its not my daily phone yet. im very familiar with the note 3 n900t but im finding they are very different. any advice would be appreciated!

If you just unlocked your bootloader and thats it, your rom should still be the stock one.

OTA fails , dm-verity fails

Hi there
after following a guide on how to downgrade from cm13 , i successfully finished the job and now have a COJ4 , but the prob is that every ota i get after downloading and going to recovery it says that the "dm-verity fails need to check DRK first" and just cant update , a friend said that it happened because you touched the IMEI (but everything i did was according to the guide) . ANY HELP?
(SM-910H Exynos)

FullOTA Firmware Flashing Issue

Hey there! I am on my build WAS-LX1AC185B172. its fully stock, unmodified, unrooted , stock recovery and bootloader locked. So i decided to update it to WAS-LX1AC185B181, this firmware is officialy available in my country via OTA, but it weighs 2.35 Gb and my internet connection is week so i was unable to download it via OTA. so instead i downloaded a FULL-OTA firmware from firmware finder app (my friend did it for me). and i want to install it through DLOAD (three buttons method) but its starts and stucks at 5% and throws an error "Update install failed" , I dont know what is going on. Kindly help me how to install this firmware, and also can it be flashed through TWRP. as the Update.zip file seems to be flashable. or is there any other method to do it.
Thanks in advance for your replies.

SM-G935FD Custom Binary Blocked by FRP Lock.

Hi,
I own samsung s7 edge (SM-G935FD) which i rooted and installed a custom ROM Oreo 8.1 last month. Everything was working fine till today morning. I restarted my phone and then it was show my the error message in the boot "Custom Binary Blocked by FRP Lock".
I downloaded the stock rom from sammobile.com according to the model no and country and tried to flash it using odin.
Odin got stuck in system and after several minutes i had to restart the process. Now i'm unable to install twrp recovery but phone has Samsung official recovery installed. I even tried z3x samsung tool to flash it but that also is not able to flash andas soon as i click on flash, it goes through the process and after 2 seconds it gives a success message while actually nothing changes.
I tried all the possible ways including sd card but nothing is working.
Can someone help me out and guide me through the proper way to reinstall stock ROM?
I'll really appreciate swift response.
Thanks,
