Semi-bricked phone E:Can't mount /cache/recovery/command

I got the Virtuous Unity 1.29.0 rom on my desire s and suddenly it just started to freeze so i took out the battery, put it back in and it's just stuck at the HTC screen. So i got in to clockwork recovery but there i get this error message
E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
i can do a "wipe data/factory reset" but i cant flash the Virtuous Unity ROM or restore to previous backups.
And CWM is running really slowly everything takes 10 times longer to do..
I guess the ROM freeze semi bricked the phone and damaged the recovery.
How can i fix this ?
Please help!

Have you tried a full wip as described here? If you don't have a Nandroid Back Up, do the wipes and then try a fresh install of just the rom. If that's no better you'll need to RUU.

I tried the full wipe, but i get an error message when trying to format cache..same with data.
So how do i do this RUU ?
Thanks for your help!

Push a new recovery via Fastboot, that should sort it. I'll post instructions later.

This is fixable, you have NOT bricked your phone but you'll need to RUU, and before you can do that your probably going to need to downgrade your bootloader.
What does your Hboot screen say?
There's more help here.

it says HBOOT 6.98.1002

i tried to flash it with saga_hboot_0.98.img
sending 'hboot' (1024 KB)...
OKAY [ 0.205s]
writing 'hboot'...
(bootloader) image update is bypassed!
OKAY [ 0.029s]
finished. total time: 0.241s
and on the phone it says "can not roll back hboot version"
what am i doing wrong ?

I got same issues and hope someone can help us out

Once I can get my adb working I will help, either way you'll need to read this.

OK I can confirm that this works! Its long winded but you will achieve what you want.
You'll need this, you need only go as far as downloading and installing, and then this.

1. Put the hboot.img you want to flash in the root of the sdcard.
2. In cmd run the following commands (after each command press enter):
adb devices
adb shell
su
dd if=/dev/block/mmcblk0p18 of=/sdcard/backup.img
dd if=/sdcard/hboot.img of=/dev/block/mmcblk0p18
reboot bootloader
i cant use the su command cause then i get
---------------------------------
C:\Users\Seb>adb shell
~ # su
su
/sbin/sh: su: not found
------------------------------------
so i skip it and jump to this command
dd if=/dev/block/mmcblk0p18 of=/sdcard/backup.img
and i get
----------------------------
dd: /dev/block/mmcblk0p18: I/O error
-------------------------
i dont have this backup.img file, maybe thats the problem.
where do i get it ?

without root (that's what the su-command is for) you'll proboably can't write the hboot...
and you don't need the backup.img since you are creating it yourself with the first command. what you need is the hboot.img. but as is said before, without root you can't dd...

Well i have root and s-off..unless the rom freeze messed that up too..
I read somewhere also that it's not necessary to type the su command
If ur already rooted. But i dont know i'm the noob here.
I'm going away for a couple of days so wont be able to do much untill i get back home.

Well, i know that in a normal linux, "sudo su" is to get root
Still pretty weird what you got there..

Have you renamed your file hboot.img?
Download this extract the hboot and rename it.

problem on android phone "failed to mount system invalid argument"

I heve edited the system.img.ext4 on samsung galaxy mini 2
and after i have flashed the phone i receive this error :
failed to mount system invalid argument
Flashing the system back with original phone works
What is causing this error?

Well, it really depends on your edit.

I have mounted system.img.ext4 and removed some files from it then i have recreated the image and flashed to phone but i receive this error when the phone starts.

re install the firmware or install a new one....that should serve the purpose

the phone is working when i flash the original fw but i want my modded system.img.ext4
with the modified system i receive this:
Not need checksum confirmation already executed!!... (this is normal )
then:
E:failed to mount /system (invalid argument)

@grigoreee - I have the same problem like You with system...
Do You found any solution?
I think that replace boot.img from this thread:
Code:
http://forum.xda-developers.com/showthread.php?t=1719699
end's in the same way

How did u guys extract the system.img.ext4?
using dd?

I use this method:
Code:
http://forum.xda-developers.com/archive/index.php/t-1588461.html
(in mini2 system is mount with the same parameters as described above)

No solution for this error?
I still receive the same error......

GT-n8010 (Wifi) Factory Mode

Hi,
Hope someone can figure this as its wrecking my brain.
I got an 8010 (wifi only version) a few days ago.
Did the clockwork and rooting and it was all working fine, until..
Booted it up this morning and it flashed a message 'Unfortunately, Factory Test has stopped. Factory Mode is ON!!' and gave me the 'calculator' program for putting in service codes.
I've checked the efs folder and its blank, no files. (I do not have a backup, yes I know I'm an idiot)
I've since tried flashing a number of roms, including stock. None of which have resolved the issue.
When using the stock recovery it gives me an error about being unable to mount /efs
From google it appears that the efs folder is to do with the imei and other areas. As mine is wifi only version should I even have this folder?
The note appears to work fine with the exception of having a lock screen, power off options etc.
thanks
BB

Have you tried to flash it over the PC with Odin and the Files from sammobile.com ??
Have you tried to repair the EFS with this Tool: http://forum.xda-developers.com/showthread.php?t=1308546 ?

Hi,
I have tried with the N8010XWALG4_N8010XSAALG3_XSA from sammobile but am currently running the N8010-XXALH2-XAALH2-DBT-deodexed
Strangely enough I have just tried to connect with Kies, and it wont connect gives an error of 'No Sim Card inserted unable to continue communication'
I'm wondering if I've somehow confused my device into think its a 8000, when it is in fact an 8010.
I've tried the EFS Repair, it states that Locate /efs partition failed and can't locate any backups ;-((
I've just tried reflashing a stock rom via odin, selecting the re-partition and format efs section (got nothing to lose at this stage I guess)
I've also removed clockwork mod and gone back to stock recovery, which reads E:failed to mount /efs (Invalid arument)
would anyone have the .pit file / bootloader files? or are they built into the the pda rom?
thanks
BB

Pit file
Further testing has shown that the /efs partition does not exist or has become corrupt.
Would anyone have / or could make a pit file for a 32gb gt-8010?
Failing that would anyone know the terminal commands and dev location for making the /efs partition (make2fs ??)

Did you fixed the issue?

Dont want to start another thread, i ran into this problem today and my solution
Assuming you have CWM installed on device and have androidsdk store on computer C: drive
1..Plug Device to Computer.. Reboot Device in CWM recovery/ mount storage/ mount system
2 on computer Shift+Ctrl +right click to open command window
command window type
cd c:/androidsdk/tools
adb shell
su
mke2fs /dev/block/mmcblk0p3
mount -w -t ext4 /dev/block/mmcblk0p3
reboot
this will create a generic EFS files on device
when you reboot you will see your screen with a yellow text..now time to get rid of it
root explorer/efs and delete factorymode(OFF) and replace with factorymode(ON)
reboot in recovery wipedata factory reset...done
you can do this with terminal also but i dont type well so this works best for me...tested only on 8013

Hello
I am getting the same problem.
Odin can not find partition. But I cant go to CWM, only download mode is possible. Any other way to start, it goes to a white screen...

it is just factorymode file set to on
use root enabled file manager and copy to /efs over writing current one. but it's just as easy or easer to just edit current file and change OFF to ON

Stuck at YU logo

1) Accidentally wiped all data including Internal Storage
2) Twrp 3.0 is working, but can't able to install any rom, Getting E:failed to mount / cache (Invalid argument) etc etc..
3)Getting "NO OS Installed" message in TWRP &- Internal Storage size is 0 (TWRP)
4) Followed Steps to flash factory image (WINDOWS)
Download the factory image fastboot package
Extract the contents of the fastboot package into a folder.
Download this flashing tools package
Extract the contents of the flashing tools zip into the same folder
To make sure, check that system.img, boot.img etc files are in the same folder as flash-all.bat, fastboot.exe etc
Connect your phone in fastboot mode, steps for which are : -
a. Power off your phone
b. Press and hold the Volume Up key
c. With the Volume Up key, connect the phone to your PC/Laptop with USB cable
d. You can let go off the Volume Up key when Fastboot Mode is displayed on the screen
Run flash-all.bat by double clicking on it.
A command window will open and flashing procedure will start
DO NOT disconnect the device during flashing procedure
The command window will close after the flashing process is over.
Disconnect the USB cable, and boot the phone normally by long pressing the Power button
But getting this error while flashing: http://imgur.com/g3NozUJ
After reboot,phone is stuck at YU logo..

Yuphoria stuck at YU Logo.
I had got notification for the OTA Cyanogen 12.1 Update and I had updated it. But even after reboot, the same 12.1 Update-notification would still appear again.
Later, I switched off Yuphoria to take out the External-SD-Card for data-transfer. Then when I switched on the Yuphoria, this Yu-Logo Boot-Loop Problem has started.
Now, My Yuphoria is Stuck at Yu-Logo on boot... and showing 'cannot mount partitions' errors when I boot custom-recovery twrp.
I have unlocked the bootloader.
From what I read online, I guess the memory partition-tables have got corrupted.... Now how can we solve this corrupted memory problem ?
I read about fastboot-flashing database.rfs or dbdata.rfs in some xda-developers Threads.
-----------------------------------------
I tried flash-all.bat with latest Cyanogen Official 12.1 ROM signed-fastboot.zip file... but still stuck at Yu-Logo on boot....
I fastboot boot trwp 2.6 custom-recovery.img and installed Cyanogen 12.1 ROM signed.zip file from external-sd card. But trwp says cannot mount partitions '/data', '/system', '/cache' etc...
---------------------------------------
I ran the command e2fsck /dev/block/bootdevice/by-name/system in terminal.
Then this message came : 'superblock has an invalid journal (inode 8) ext4'
I entered yes for correction multiple times and the process completed....
But still stuck at YU Logo on reboot.... Please Help.
-----------------------------------
I erased persist, then flashed persist.img.
Then I booted into twrp recovery, and adb sideload cm-12.1-YPG4PAS8A8-lettuce-signed.zip
The sideload started and then stopped with error : failed to unmount /cache ; failed to unmount /data ;

Only TWRP 2.8.7.2 and lower versions boots successfully in my Yuphoria.
TWRP 3.0.0 will not boot successfully. The TWRP logo will appear and then show command errors, and the phone will restart.
Please help me reinstall OS in my softbricked Yuphoria.

same prblm
anyone got solution for this ??

Exact problem.........
I ve gave it micromax service center, they asked 400 and began their work. after some time the man came out and sad, this is a board problem, you have to change the board. My friend is an embedded service engineer. He is saying its just a soft brick and the device is perfectly working. Those knowledgeless idiots dont want to find solution for this, the simply trying to change the board. Friends the problem we have is 100% a software issue, pls dont fall in their trap............

Same issue
Guys anyone got the solution ? Please help ...

Anybody got solutions, please respond

Same here
I tried everything but nothing seems to work. Someone help....

Seems to be Soft-Brick Software issue....
TWRP Recovery is not able to mount the /system , /cache and /data partitions...
but inside TWRP Recovery FileManager , we can open and browse all partiton files and system folders/files in /dev directory....
Also the TWRP Terminal shell can be used to run e2fsck and mke2fs commands...
So I think the /system, /cache and /data , and other corrupted android partitions like /misc can be repaired and mounted again, using the right steps and procedures....
Then I believe TWRP Recovery will mount partitons again and work, and we will be able to install/flash new ROM... Phone will boot into OS again...
We need Somebody with enough technical know-how to run Terminal Shell commands and repair corrupted android partitions.
Please if someone can help, would be greatful...

I ve gave it micromax service center, they asked 400 and began their work. after some time the man came out and sad, this is a board problem, you have to change the board. My friend is an embedded service engineer. He is saying its just a soft brick and the device is perfectly working. Those knowledgeless idiots dont want to find solution for this, the simply trying to change the board. Friends the problem we have is 100% a software issue, pls dont fall in their trap............

Same problem here !!
Tried to flash the ROM with QFIL but the port is not detected by the software.
Also tried with fastboot.exe method still the same sometimes it says write failed for Size too large of system.img and if I change the default size limit (with -S option) it says "Error : Write failed"

You just gotta flash regular CSC and not home CSC. It will wipe your device but it fixes the problem.
