[Q] E: Failed to mount / efs(invalid argument)

Hello All,
I have a Samsung Galaxy I9070.
I have rooted the device from http://forum.xda-developers.com/showthread.php?t=2087424 and it worked fine.
After that i tried to Flash a CWM 5 XX version,
1. I wiped all the data/reset
2. While flashing it from "Apply update from external storage" the device got powered off.
3, I did a hard restart to enter recovery mode and then CWM showed up and stared to blink.
4. Now i got a error as E: Failed to mount / efs(invalid argument).
5. i have restarted the device.
6. i am getting a error as Unfortunately,the processcom.google.process.gapps has stopped.
Now i thought to flash a new rom from SD card and then it may work.
1. i flashed cynogen Mod 11.0
2. after that it is just stuck at the starting screen of Cynogen Mod logo.
Now i have restored the Jellybean from Odin and still i get the same error as Unfortunately,the processcom.google.process.gapps has stopped.
and also in the recovery mode E: Failed to mount / efs(invalid argument). this error stayed.
Please help me to get the device back to working.
Just an update-
1. i have used ODIN and installed Ginger bread on it.
2. The phone got turned on and working.
3. I am not able to connect to Wifi.
4. But when i go to recovery mode, it still shows that error as E: Failed to mount / efs(invalid argument).
5. I think this this EFS file is corrupted and so Mac address of the device is corrupted.
How do i fix this error. Please help. i have not taken a backup of this efs.
Thanks All.

Try this maybe.

I have the same problem.
I wanted to flash a new rom and and deleted some unnecessary folders and I deleted some hidden folders.
I can enter on recovery/downloading but I can't flash any rom.
I've flashed a stock rom (JB) via Odin and it restart the device on setup screen but it gives 2 errors (I'll post the images).
I've flashed another stock rom (GB) via Odin and it restart the device on the home screen but whenever I go to recovery it shows me the the message E: Failed to mount / efs (Invalid argument)
I've tried some methods I've found on the forum but they didn't work.
The link posted don't work for me.
My phone connect to 3G and don't shows the error "Baseband and IMEI unknown / Baseband unchangeable".
I didn't find any thread on the forum with the answer for my problem.

Recovery Setup not working

Hallo,
im quite new and i was trying to install custom ROMs on my gt-p1000. my tab is rooted, but i didnt do it myself
i installed rom manager from the appstore and tried to install cwm and twrp, but when i try to boot this happens:
Code:
[...]
E:part(1) DATA Checksum Error
E:part(1) Checksum Error
Internal MMC checksum verify failed.
Installing Package
[...]
E:failed to verify whole-file signature
E:signature verification failed
Installation aborted
i assume im directed to the normal recovery mode, because i cant install custorm roms from here because there is some sort of check which doenst pass.
I tried to repartition using Odin, but no success. I just selected the checkbox for repartition and reboot and waited. But that didnt help.
Does anyone know why this is happening?
Thanks !

[EMERGENCY] Unable to install anything from recovery as well as from miflash tool.

My current situation:
->twrp installed
->everything formatted!(sdcard,data etc)
->unable to mount /system error in both cwm/twrp
-> No OS installed
->stock partition
->unable to flash any ROM, yes any custom ROM out there(from sideload or from sdcard) with this error "failed to mount /dev/block/platform/msm_sdcc.1/by-name/system at /system No such file or directory
unmount of /system failed; no such volume"
->Unable to flash MI roms through miflash because of unspecified error (0xffffff01)!
-> hope from you guys.
My mi3 was running on lollipop ivan ROM. everything was ok. I thought lets flash mokee. after flashing mokee and using it for few days(With no gapps, unable to flash) I reverted back to ivan AOSP from my old backup(thank god!).
Crysis started after this point.
I extended the partition from this guid->http://forum.xda-developers.com/xiaomi-mi-3/general/howto-resize-extend-partition-capacity-t3011918
It was successfull. But whenever I tried to flash any rom , it gave me the error mentioned above(failed to mount /dev/block/...)
So I fomatted everything, and reverted the partition changes to stock. But the error was still there, on both cwm/twrp.
So I thought of using miflash method to solve this issue. But miflash is giving unspecified error. Yes, I'm doing everything correctly in miflash method,no space in folder name and etc.But it's giving error.
Now I don't have anything in my phone except twrp. Cant flash AOSP/CM romes because of the error and cannot flash MIUI from meflash. What should I do? Seriously I'm completely broken. Need Help. :crying::crying:

If under warranty take it to the nearest service center. They should fix your phone.

Flash MIUI through recovery method.

dude, flash back to stock partitions and only after u flash that through cwm/twrp (try both if its still not working ) it will work Mi Flash. I experienced the same problem, just kept flashing (cmw/twrp) the stock partition zip and it worked

help pls rog phone 2 soft bricked

Getting Failed to clear BCB message: failed to open /dev/block/boot/device/by-name/misc: No such file or directory after phone crash​
cant solve this please help
tried edl recovery flashed well but didnt solve problem
i have unlocked the bootloader and flashed many raw firmware didnt solved problem
flashed twrp sucessfully but cant mount storage intenal storage 0mb and cant swipe anything
get this message everytime in recovery
Getting Failed to clear BCB message: failed to open /dev/block/boot/device/by-name/misc: No such file or directory after phone crash​
please help

I have no idea it helps, I had my phone crash on me and me trying my old-and-tried flashing etc. I did not have such BCB message, but it sounds like there is an issue with the partitions or partitioning.
There are nice YouTube videos at least that show how to flash the stock ROM (not giving link here for advertising etc).
it boils down to (FIRST get your data off the phone as you are going to lose this)
- TWRP being bootable
- in TWRP: factory reset, wipe data
- flash stock ROM twice: to partition A and after reboot to TWRP, to partition B. I do not know why this needs to be done, love to learn it by myself.
- flash without wiping a custom recovery if wanted.
- restore your data
