[Galaxy Note5 Q&A, Help & Troubleshooting] magix01:
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.

Regards,

magix01
[Galaxy Note5 Q&A, Help & Troubleshooting] 121man:
Cool dude, I assume this voids warranty etc....

Also would I be able to get and update OTA once done?

Also will this trip knox?
[Galaxy Note5 Q&A, Help & Troubleshooting] magix01:
Well we need root, thus knox is void. But dm-verity is usually broken by modding system, installing roms and editing efs partition. So i assume that knox is already tripped.

Hi im using a sm-g928t with a dm verity drk error in my recovery, i was stuck in a boot loop and had to install twrp>5.11>and then cf autoroot in order for it to boot up, but alas now its constantly searching and the recovery went back to stock, also a 911 adress error i disabled in the device manager.

can this error be the reason my cell (t mobile) is constantly searching? i have full bars but no signal :(

been a few days without cell, need for work :(

please any input would be amazing

The device isn't blacklisted is it? Also does it show the correct IMEI under about device in settings?

not blacklisted, and correct imei, checked on the t mobile imei checker, pretty sure i can figure out the searching issue in time, having alot of trouble finding difinitive information on getting rid of this awful error code.
[Galaxy Note5 Q&A, Help & Troubleshooting] Jammol:
We fixed it by using the mm beta and supersu v2.64 I think. We got supersu to patch dm-verity (it does so anyways), and went back to stock LP and no more error. It took a lot of flashing.

Hello,

Could you please help me regarding this issue? I have also an SMg-920F S6 and I don't know how to bypass this error.

I also have teamviwer, skype and everything is needed. Could you please help me? Or at least send me the stock kernel for S6 920f to adryan289@yahoo.com.

Also any remote assistance via TeamV is appreciated. Thank you in advance!

Hi Magix,

Sorry if this is double posting, but I'm trying to get my s6 920f fixed and with no success. I went to a local GSM repair shop and they tried to flash all the possible software with a "box" and also with no success. Then I went to our regional country Samsung service and I wanted to pay for the software "re-write", but they didn't helped me at all because the phone lost the warranty doe to root.

Could you please assist me via teamviwer please? I also accept a temp solution just to make my phone working.

Thank you.

HELP

Hey i got a problem, i have tried installing firmware from samfirm, but my country (denmark) isn't there so i choose an other tried with Germany and Brazil.. but now it says: Supported api 3

dm-verity verification failed...

Need to check DRK first

What do i do ? and how should i choose the right firmware when my country is not on Samfirm ? I don't care if i need to root it or what ever, i just need help on what to do to make it turn on.. i got it very cheap because it was a demo, and i followed a guide how to remove retail mode, but it failed so i used a guide to flash firmware, and now i cannot turn it on :(

Would this work for Verizon Note 4? I was rooted on MM with a ported variant S7 rom for a few days than started getting problems so I odined official MM and have had the EFS failed to mount and dm verity issue in stock recovery since... I'd really like to get this fixed even if it takes sending it to one of you XDA senior members... will gladly pay for your service!
[Galaxy Note5 Q&A, Help & Troubleshooting] Sleepycloud:
It is a permanent fix. Man... My device was so f'd up that it would not boot. Now it works fine, and all the extra partitions that got added when I flashed the bogus .tar are gone. He used Octoplus to repair my device back to a 100% stock factory state, except for the Knox counter.

[MENTION=5222560]lorilucille9[/MENTION]

Your efs partition is damaged if you get invalid argument if you want to fix it you need efs backup and efs format, if you want to keep your own imei.

I created tutorial here

http://xdaforums.com/note-4/orig-development/fix-drk-dm-verity-factory-csc-serial-t3422965

Dont follow tutorial unless you already have efs backup and nv_data.bin files or you are toast. Since you have to format your efs because it cant mount.
[Galaxy Note5 Q&A, Help & Troubleshooting] lorilucille9:
Unfortunately my backup was corrupted by twrp... twrp was getting to be unreliable for me. When making a backup of my rom and folders it would say successful but more than half the time restore would fail. I'm at a loss what to do [emoji31]
[Galaxy Note5 Q&A, Help & Troubleshooting] magix01:
I have sent you a PM, maybe there is a way to help you. Regards
[Galaxy Note5 Q&A, Help & Troubleshooting] lorilucille9:
After trying repeatedly flashing and unlocking bootloader my SD card that had backup was erased. Here is the thing though... the phone still worked for calls and data with no problem. The only thing I noticed that didn't was screen mirroring. My Bluetooth and WiFi worked as well. I went and bought a new phone so now my Note 4 can only be used via WiFi but my IMEI still shows good. My ICCID number is not the same as it is listed on the OEM box and my MEID number cuts of the last digit off but matches other than that. As you can see in screenshot the network, mobile network type and service state are wrong.

thanks for help and reaching out! Maybe someone will have an ah ha moment and maybe these settings can be fixed and it's not as bad as corrupted efs folder?
[Galaxy Note5 Q&A, Help & Troubleshooting] magix01:
[MENTION=5222560]lorilucille9[/MENTION]

Well if you EFS nv_data.bin and other network related files are ok, which i assume they are since your imei is valid than that is very good. But if you get error in recovery about bad mount, than its best to manually backup efs and format/mount it again, then restore those files manually and try it that way.
[Galaxy Note5 Q&A, Help & Troubleshooting] lorilucille9:
When you have root and you look into your efs folder should there be files showing because I had an empty folder unless it's solid explorer not letting me see them? I don't have much faith in TWRP to do backups anymore either.
[Galaxy Note5 Q&A, Help & Troubleshooting] magix01:
[MENTION=5222560]lorilucille9[/MENTION]

I pmed you with skype id add me, solid exporer dont show those files, type with terminal emulator:

1. su

2. cd /efs

3. ls -la

Then post ss back, commands are case sensitive.
[Galaxy Note5 Q&A, Help & Troubleshooting] lorilucille9:
Sorry I don't have Skype and at work now... do I need root to do this because now I'm on official MM and would have to go back to LP to root.
[Galaxy Note5 Q&A, Help & Troubleshooting] magix01:
[MENTION=5222560]lorilucille9[/MENTION]

Yes you need root /efs is sensitive partition, there is CF autoroot for MM for note 4 i guess.
[Galaxy Note5 Q&A, Help & Troubleshooting] lorilucille9:
I'll go back to LP and do bootloader unlock than... will let you know... appreciate the help and big thanks!
[Galaxy Note5 Q&A, Help & Troubleshooting] lorilucille9:
In process of doing bootloader unlock on LP again. I see now that the settings have changed and are different on LP (screenshot). Mobile network type is not LTE but IMEI is still good except for the ICCID which is not the same number on the OEM box. Should I still do these commands in terminal emulator downloaded from playstore on my phone still? I also compared the screen settings against my S7 Edge and noticed the configuration version shows "Not Available" (screenshot).
[Galaxy Note5 Q&A, Help & Troubleshooting] Jammol:
Not that simple. Of the EFS partition is messed up they are out of luck unless they have a backup of it.
[Galaxy Note5 Q&A, Help & Troubleshooting] lorilucille9:
I was able to go back to LP and unlock the bootloader and Odin TWRP onto my device. I was also able to do a backup of my efs folder as well. I haven't done anything further because I know from past tries that TWRP will not flash roms due to my settings being screwed up from the efs folder mount and/or dm verity failed issues maybe? How can I fix the efs issue from this point? I don't have Supersu on the phone because it conflicts with Kingroot and I can't get that off either... it won't let me uninstall it. So it looks like I'm kinda screwed unless you have more advice? I did not do the terminal emulator commands either since you thought I was on MM then as well. Appreciate the help so far... be so much easier if I could send it to someone reliable to fix and pay for it at this point.

Copied from other thread, Thanks in advances.

I don't want to be an alarmist but back on 17th June 2016 I created this thread DM Verification failure , Please flash ENG binary then install DNK

At the time I wasn't sure what had caused the problem but last night with a different phone I used KingoRoot and it corrupted a second phone of mine. Now two out of three of my Verizon Note 4's have the dm-verification-failure.

The symptoms of the problem are when I am navigating some of the swipes lag. Sometimes when typing there is a lag delay before it is entered. Sometimes Wifi lags before it is turned on and the phone forgets my wifi password.

I found this thread How to solve dm-verity verification failed/need to check drk first on samsung devices but I don't have the experience to do it. Can a developer create the fix for the Verizon Note 4 , PLEASE, Thanks

I can say that I tried every suggestion out there, but was not able to fix it definitively. I finally reached out to IMEIRescue and he fixed it for me (for the cost of a few beers) via remote.

He used GC ProKey, but you really need to do some research if you're going to attempt it yourself!

Hello, I have a Samsung Galaxy S6 that I bought second hand on ebay. It was working fine until recently when i began an update and put it down for a bit. I came back and it had apperently died durring the update is what im guessing. Anyway, I tried flashing the rom on in to a 6.0.1 and i also get that DM-Verity Need to check drk error... But mines a bit different.. I flashed the most recent 6.0.1 onto the phone from SamFirmware just fine... When the phone restarted it starts the blue "update" screen with a loading bar. It gets to about 24% then jumps to about 32% and briefly says "erasing" and restarts once more... It then proceeds to say something along the lines of "Supported api: 3" in white and "E:failed setting up dirty target" in red.. at the recovery type screen. I can then restart the phone to VERY BRIEFLY see the blue "updating" screen and then i get the final error i see which is the DM-verity verification failed... need to chekc DRK first....
