Hi,
My phone (S7) got into a boot loop for no apparent reason. I noticed it was a bit hot and it froze a couple of times so I rebooted it and after that it was stuck in a boot loop no matter what. I then tried "flashing" the latest firmware with Odin3 to fix it. Everything was fine in Odin but after the phone rebooted, it couldn't finish installing the patch... It showed an "error!' screen then booted into Android Recovery with these logs:
#fail to open recovery_cause(No such file or directory)#
#Reboot Recovery Cause is UNKNOWN
No Support SINGLE-SKU

E:failed to mount /efs (Invalid argument)

E:failed to mount /efs (Invalid argument)
E:failed to mount /efs (Invalid argument)
dm-verity verification failed...
E:failed to clear BCB message: failed to fin /misc partition

At this point I'm not sure what I can do... I would really like to avoid a factory reset as I have a lot of data on my phone I would like to keep.
Thanks!

Hello, this problem is very common for people that root their phones if you get drk error then there are 2 methods to solve this
Method one : easy
Just flash cf autoroot with odin download the file for your phone and flash it in ap
You may get stuck or get bootloops in splash screen or red errors just wait patiently until rom boots
Method 2 : for if you want no root (ota still impossible)
Flash twrp with odin, then download the no verity file
And move it to your phone, in twrp tap on install and select the file
https://build.nethunter.com/android-tools/no-verity-opt-encrypt/
Just download the latest version of the file (6.0)
Now wait until rom boots
-----------------------------------------------------------------------------------
Please donate and like if you think i deserved it,
If it didnt work you don't have to do it
Happy flashing and good luck
Dont forget to update me after following the steps
I'm a total newbie when it comes to phone flashing, I have a few questions. If I decide to use autoroot, is there a chance for a brick? What could go wrong? I think there's no turning back from rooting a device, right? I don't want to lose my data.
Also, I can't seem to make TWRP work because when I plug the phone to the pc it doesn't recognize it and I can't access it whatsoever to put the files in there, even after installing the drivers.
Thanks!

Flash the stock firmware again but from download the firmware from Samfirm application. Please use the HOME_CSC too or your device is wiped. If you need the firmware just post modelnumber or name idk and CSC code and i can post a link with the firmware for you. TWRP can't mount /data and you will need to format your phone with means you lose everything.

Same issue
I have the same issue. I cant boot into download mode at all to even attempt to flash anything

Hi everyone!
I want to ask for help.
Long story short:
Twrp 3.0.2 as custom recovery
Issue: - Takes 5 minutes to boot into recovery,
- Resets itself every time booting into it
- Wipe Data/Factory Reset not working at all
I've tried File system change, repair system file, change system file but none of these are working either. All of this ends with the same error messages:
Failed to mount '/data' (invalid argument)
Failed to mount '/cache' (invalid argument)
Unable to mount storage
Unable to wipe Dalvik, Cache, Data, System
SO I PRETTY MUCH CAN'T DO ANYTHING
Tried installing new stock Rom via Odin, full Re-Partition with correct GT-S7275R PIT file, correct BOOTLOADER file, correct FIRMWARE for my region, correct MODEM file and correct CSC file. Everything is correct and legit. Odin flashes, message is PASS, phone reboots into recovery, same recovery, same reset on recovery, restarting my phone, galaxy ace 3 logo, and goes into bootloop.
Tried with Samsung Kies, entered my phone model and S/N number, correct firmware showed up, Kies installed it. Nothing changed still!!!
Tried legit stock recovery for my model, odin flashed it, PASS, phone reboots into the same TWRP recovery... like what the hell!!
Tried flashing CWM recovery, Odin okay, PASS, reboots again into TWRP....
I did not touch my phone, I just didn't use it since 2016, the phone drained and switched off, Since then I bought a new S7, I wanted to check on my Ace 3, so yesterday I've put my Ace 3 in charger, waited a few minutes, tried to boot it, and it got stuck on boot animation... since then, I tried literally everything to get it work.. EVEN WITH COMMANDS IN THE TWRP TERMINAL. NOTHING!!!
In 2016 the phone's status was:
Custom ROM:
cm-12.1-20151001-UNOFFICIAL-loganreltexx
Gapps micro:
tk_gapps-modular-micro-5.1.1-20150927-signed
TWRP:
twrp-2.8.6.0 (now 3.0.2)
BACK THEN, I was able to flash anything, install any .zip, wipe any data, reset my phone, boot normally.
Someone, who knows what the hell is going on, and how to fix it, please tell me.
Thanks.
Remember when you flash the stock firmware via Odin you have to factory reset the phone. It won't boot if you don't reset it.

If you flash the original firmware via Odin, you should have the original recovery as well.. maybe download the firmware from a different source.

hello iv been trying to flash emui 5.0 firmware but i always get the same error when i flash the system.img it says FAILED (remote: sparse flash write failure)
and when i tried to flash the cust.img i get FAILED (remote: partition error). so like you figured i damaged the partition
i tried to wipe cache, format data but still doesn't work to flash the system.img and the cust.img but the boot and recovery images are fine to flash.
i also tried the dload method with no luck. so it started of when i updated to nougat 7.0 emui 5.0 from emui 4.1 marsmallow 6.0.1 it didn't update properly and i got some other version
with only google voice input, and crashed. so i decided to flash it manually instead in fastboot but before i flashed i went in to twrp and wiped everything and formated the data.
then i flashed the boot,recovery,cust,system images from the update.app to emui 5.0 for my device but then i damage my partition and got stuck on a boot loop. after that i went
in twrp and wiped everything again flashed the images again but then system and cust img failed errors above. would appreciate any assistance thank you.
are you able to flash any custom ROM?
Try booting to TWRP from TWRP and see if it makes any different instead directly wiping and booting.

You need to flash the TWRP 3.1 for EMUI 5.0. Once you flash the correct file you can boot.
Do one thing, remove USB and just press power key, it will boot to system.
Sorry my bad english.
If you connect the phone to PC, you can browse the internal or external storage?
If you do, or you have an sdcard, use it to dload mode to flash firmware. Use rollback package to revert back to an old firmware. And don't use twrp to flashing firmwares. Its wont work perfectly with nougat firmwares. Dont use it.
From twrp did not work for me. This method send my phone to bootloop and later just booting to erecovery, or stay a permanent bootloop. TWRP gone and just the dload method works 100 percentage.

Help! I cannot use my phone because while updating to OERO it failed saying :
An error has occurred during update and you have to use emergency firmware recovery on smart switch PC software but smartswitch says it is unsupported device. I have access in download mode but cannot accomplish anything because;
1). Odin fails every time ( gets stuck while flashing system.img (AP)
2). My phone cannot find /system. I have tried restoring my phone to stock, but Odin fails.
The bottom of my recover screen says "dm-verity verification failed ... " And "E: failed to mount /system (Invalid argument)".
Any help or guidance is greatly appreciated.
Thanks.

I am in swtizerland with CSC VFG and wanted to flash oreo from UK BTU. I flashed it via odin 3.13.1. and couldn't boot into system only into recovery in which i get the message :
No support SINGLE-SKU
Supported API: 3
Dm-verify error…
E:failed to mount /system (invalid argument)
I can see that in recovery I still have the firmware from switzerland G930FXXS2RC3 instead of UK G930FXXU2ERD5.
In download mode I can see Secure download: enabled and FRP lock : ON, I also remember that i didn't toggle the OEM unlock since flashing official firmware you don't need to be OEM unlocked.
This work for me:
Download BTU Oreo stock files.
Download Odin 3.13...
Change AP file format from *.md5 to *.tar
Flash only APxxx.tar file
Wait to reboot
Enjoy
Hope it work. Good luck!
I was on Oreo BTU Stock and try rooting flashing tarp and when boot on TWRP there was lost data partition. I wasn't able to flash anything via twrp and Odin just reboot the phone. Then I did those steps and and boot normally and everything ok, no data loss.

Hello bro.
I did not come around any fix for that, I had to take it to a repair shop and they fixed it for 40 euros.
While searching on internetil I found some guys who said that they could repair it via Teamviewer from their shop but also had to be paid 35 dollars.
After a while, I found a program which is called ; Octopus Box Samsung which seems to repair NVM, write firmware on samsung phones. I haven't tried it but I'm sure it would work if you do a little research on it and watching tutorials on how to use the app.
Best of luck, and let me know if you come to a fix.
Edit: apparently you need this program and a Samsung Micro UART cable with 530k resistor in irder to work.

NVM is the memory of the phone on which your firmware operates. I never used the octopus box but I read for it on google.and watched som.youtube videos on which they repair NVM through the octopus box. I never heard about z3x box but I assume it does the same function.

Hello friends, when I flash Combination file, or stock file , my phone boots and hang at start up logo, while I restart to recovery I see this error (E:Failed to mount efs, Invalid Argument)?
Can anyone help?
What have you done ? Trying to root and lost your IMEI ?
If so, then go to recovery and do all of the wipes and format Data. Once done, then just flash the exact same ROM as the one which is already installed on your phone.

This steps does not work, I need EFS for A8 2018.
I'm having the same problem, I've tried everything. z3x, Odin , won't even let me flash from sd card. Won't load into Oreo just keeps rebooting. I can get into recovery but does nothing as well as boot loader. I did have a utility im pretty sure was made by FACTORY BINARY that was it's own little OS with a bunch of little tools. I have a sm-a530w flashed with boot loader 4 ugggg. If anyone can help find that utility that will wipe the whole thing and let me flash from scratch that would be awesome. I've tryed miracle, Uni-Android, samsung tools 29.5 and flashing with odin. Lets me flash factory FIRMWARE but still error's out on the "Failed to mount EFS" HELPPLEASE
A quick suggestion you probably tried, but i've had failure at boot in the past after returning to stock via odin if i used home_csc. So, if you haven't already tried, use just csc. No home. On home it does system.img until the end, no user_data . Not sure at all what the deal is but it's all i can suggest. Get 'er goin'!
:Failed to mount EFS
Yes I think I tried that, but at this point, I try again. Any more suggestions would be greatly appreciated. An A8 in mint shape just hurts LOL.
Hello,
My phone(Samsung galaxy s8) just had a crash and is stuck on the blue screen with "Installing update". After several seconds the screen goes away and boots straight into the recovery mode.
The log that i see in the recovery is :
Fail to open recovery_cause(No such file or directory)
Failed to mount /efs
Unknown volume for path /odm
dm-verity verification failed
I tried to install the stock firmware (I cant link to the webpage but im 100% sure its the correct one) but it wont boot and goes to the "Installing update" again and after that to the recovery.
I tried installing twrp but it wont install due a FRP lock. i read that you should wipe your data and factory reset. Also tried that but again no succes.
Can someone please help me.
Thanks in advance

I'm going to take a guess here, you had the device rooted and then you tried to apply an OTA stock update while the device was rooted? Tyically, stock OTA updates can't be applied to devices that have been rooted because the updates require the device to have an unmodified system partition(no root) and they require stock recovery instead of custom recovery. There are "some" devices that can apply stock updates while rooted, but those are few and far between.
If that is what you did, you need to do some searching for repairing failed OTA updates on rooted devices.
