[Samsung Galaxy S7 Questions and Answers] chestertjuh:
Dear all,

I hope you can provide me some help since i'm not sure what to try anymore. I'm allready struggling to get it solved for several days.

I tried to root my phone and it turned out to be working. Upon a reboot after the installation of a SD-Card partitioning app ( i dont know the name anymore since i thought it would be harmless.. but i was wrong ).

After the reboot the phone wouldn't turn on or let me restore so i decided ( to make it worse.. ) to put a custom rom since the data on the phone wasent important to me.

After installing TWRP everything seemed fine and when installing the zip's i noticed the message Failed to mount /EFS (invalid argument).

I tried several recovery's recommended on the forum but nothing works for me.

What i tried so far.

At first i tried the original firmware and software.

Tried to restore the folder and fix permissions

Tried the ADB commands but that doesent help either

Tried to restore the PIT file without any positive result.

Tried to completely wipe and restore also without any positive result.

Errors when installing rom :

Failed to mount /dev/block/platform/155a0000.ufs/by-name/EFS

at /EFS invalid argument

Error in TWRP

Failed to mount /EFS (invalid argument)

Can anyone provide me help or know how to solve this for me ?

Model SM-G930F

Info from KIES3 : PDA:QG4 CSC:QD1 PHONE:QD7 (DBT)

Thanks in advance!

Offering a small reward/thank you. for figuring this out :) without needing to send it to the service centre.
[Samsung Galaxy S7 Questions and Answers] *Detection*:
No need for rewards, this is XDA :)

Did you try using ODIN 3.12.3 or newer to flash the stock ROM from Download mode?

If you partitioned the internal storage, you might need to select "Repartition" in ODIN when you flash the firmware

Add AP, CP, BL and CSC (CSC will wipe the phone after the flash)

Put the phone in Download mode (Volume Down & Home & power)

Connect phone to USB > PC

Make sure COM port is highlighted at the top of ODIN to confirm connection to phone

Hit Start

All being well the phone should auto reboot and boot into Android, first boot will take a while

Get the stock ROM from updato.com

http://updato.com/firmware-archive-select-model?q=G930F

Select your region from the drop down, or use unbranded United Kingdom (BTU or XEU)
[Samsung Galaxy S7 Questions and Answers] chestertjuh:
Just tried to be sure. After loading/flashing stock rom it goes into recovery mode displaying the following error :

No Support SINGLE-SKU

Supported API: 3

E: Failed to mount /efs (Invalid argument)

E: Failed to mount /efs (Invalid argument)

E: Failed to mount /efs (Invalid argument)

dm-verity error...

I didnt receive any errors during flashing or in ODIN. Only error shows up in recovery mode after flashing.

Did you backup the EFS partition before messing with the sd-card partitioning app?

EFS partition contains IMEI and Radios needed for calls etc

Does Download mode definitely say G930F?

Give Smart Switch firmware recovery a shot too, see if that can do anything

Similar issue here, answer was taking it to a tech repair centre

https://xdaforums.com/s7-edge/help/brick-phone-challenge-dm-verity-error-t3597849
[Samsung Galaxy S7 Questions and Answers] chestertjuh:
I have checked the model to be sure and it says G930F so that is correct. All firmware is also downloaded for the G930F. Smart Switch also doesent work and i return to recovery with the mounting error. I tried repartitioning with ODIN but also that didnt fix the problem. The DM-Verity error is easily to fix when flashing the right zip but i keep bumping into the /EFS error over and over.
[Samsung Galaxy S7 Questions and Answers] chestertjuh:
Had to have the board replaced by a repair centre. Since they couldnt fix this issue due to, too many wipes and corrupted partitions. Now its working fine again.
[Samsung Galaxy S7 Questions and Answers] ganapathi.sub@gmail.com:
How much did they charge for the Board?
[Samsung Galaxy S7 Questions and Answers] Flashyflasherson616:
SOS Mount /efs fail smg930w8

So Ive basically tried everything as well but i dont want to give up and get a perfectly fine board replaced. Has any one found a soulution to this issue yet? Or would anyone be willing to troubleshoot this with me?
[Samsung Galaxy S7 Questions and Answers] cooltt:
You have to understand that if the EFS is corrupt, missing info, completely blank etc, nothing else will work on the device. You need to flash a back up of YOUR Efs for your phone to ever work correctly again. You can flash a copy of another same model EFS but then you will have to change the Imei to your own and its not an easy process but there are guides on Google on how to do this.
[Samsung Galaxy A3, A5, A7 (2017) Questions & Answe] KimJungCool:
Hello, fellow A720f owners. I messed up my Type-C port. While it can still definitely charge, still quite fast at that, the data transfer doesn't seem to work. So, no Odin for me.

Luckily, I've already rooted the phone and installed cmw as my custom recovery way before I messed the port up (submerged phone in a swimming pool for too long)

My phone went into a boot loop after I tried unrooting via SuperSu and rerooting via Kingroot (I was trying to see if I could really root my phone through Kingroot.) Because I saw that Kingroot was performing some shady actions (it installed itself as a system app for one), used root explorer to remove Kingroot from the systems folder.

I was planning on flashing a custom ROM via sd card, but I haven't seen any roms for the a7 2017 (6.0.1)

I failed to make a backup as well as I wasn't expecting things to go awry. (lesson learned)

So, I now have a question that you probably already know because of the title.

Inquiry: Is it possible to restore my phone using someone else's backup?

Request: If yes, is anyone of you willing to send me a backup so I can restore my phone? What other measures should I take to ensure that the procedure will succeed?

Some info I left out:

Model: SM-A720f (Open line, Philippines) [Surprise! I'm not Korean haha]

Build: A720FXXU1AQC5

Android Version: 6.0.1

Recovery: CWM

ROM: Stock

Thank you all in advance. :)

Good to have a TWRP for both variants.

Where did the term "International" come from? Both the Qualcomm and Meditatek versions of the Moto E4 are sold in several countries, so using the term "International" to refer to the MediaTek version seems confusing to me. Users may think "International" works on phones sold in all countries. I think it would be better to name this as TWRP for the MediaTek version rather than "International".
[Moto E4 ROMs, Kernels, Recoveries, & Other Develop] andMego:
But not all users know what mediatek is so It probably makes sense to put "(mediatek)" in the title

i have some strange problem with my device boot image. it unable to start any external service which i added after unpacking the boot image.

i write this command in init.rc to change sysinit file permission "chmod 0755 /sbin/sysinit". but no 0755 permission to sysinit. also daemon process start by init such as "service sysinit /sbin/sysinit \n oneshot" unable to start on boot. so no init.d support

Try this. Init.d should be enabled. I also removed dm-verity and force encrypt and made it insecure. I wanted to make a flashable zip but I have no device info to do so. You'll have to extract it and flash the img. You might need to add the etc/init.d folder and set it's permissions manually. Let me know if it works ok.

2. This Dialer works with EZDial from www.mesoftware.biz (=The Fastest Smartdialing software available) You will not believe how fast the kaiser dialer can be!

3. Now this Dialer supports SmartDialing!

4. This dialer supports WM6 and WM6.1 roms.

This is how it looks like:

after the installation you need to switch off Smartdialing.

then install another smartdialing app (EZDIAL) and it will work.

and will produce the FASTEST DIALER AVAILABLE! for the Kaiser.
