[Q] [HELP] Error mounting /system & /cache in stock recovery

Guys need your attention & a consoling solution for my bricked phone, that can go in recovery & download mode. But the stock recovery mode says
--Applying multi CSC--
E:failed to mount/system(Invalid arguement)
E:failed to mount/cache(Invalid arguement)
E:cant open /cache/recovery/log
The troubled began when i added internet tweaks to build.prop.
When i reboot, phone got stuck at samsung logo.
Then when i opened cwm their i found error mounting system, & was unable to restore backups but when i used Rafael's "FORMAT ALL EXT4.ZIP" i was able to mount /system in cmw but these errors got shifted to stock recovery
now i'm able to flash zips & restore backups but of no use. still phone stuck at logo
Do i need to take my phone to Service center or any other advices?

The reason you are getting those errors is that stock recovery cannot handle ext4, that's normal.
Probably the simplest thing to do would be to follow the unbrick tutorial:

thanks for specifying the Ext4 problem...
can i get back to Ext3 by flashing any zip through cmw recovery?

Well rfs is the default file system format, not ext3. If you use this version of CWM then you can go to mounts and storage > format /cache, /system and /data back to rfs. However you will obviously now have no ROM on your phone so will still need to either restore a backup or flash a zip of a ROM that includes the entire /system folder, which is most, if not all. I've never tried this technique by the way, so no guarantees here.
Also try to restore only Nandroid backups made with the same version of CWM that you are using to avoid problems.

Soft Brick pt7310? can't mount /data - /sdcard , bootloop

hi everybody.
yesterday i have flashed my p7310 from stock honeycomp to cm10.1-experimental.
descriped here: http://forum.xda-developers.com/showthread.php?t=2060530
works good, just the strange screen flickering after wakeup from standby.
see here: http://forum.xda-developers.com/showthread.php?t=1989398&highlight=wakeup
because this I tried to reflash it with GT-P7310_XAR_P7310UELA3.
descriped link above.
now I'm in a bad state.
actually cwm 5.5.0.4 is installed.
if I try to boot my rom it loops at samsung logo.
if I select "wipe data/factory reset" in cwm I get:
-- wiping data...
formatting /data
error mounting /data!
skipping format...
formatting /cache
formatting /sd-ext
formatting /sdcard/.android_secure...
error mounting /sdcard/.android_secure!
skipping format...
data wipe complete
I have tryed to install stock rom P7310XXLPO_P7310XEULPO_XEU.zip via odin. install works, bootloop
installed ClockworkMod_Recovery_v5.5.0.4.tar via odin. install works
repartitioned via odin (p5_0614.pit) and install stock rom, install works, but still bootloop.
if i connect via adb i can push Clockwork_Recovery_6.0.0.8_GT-P7310.zip to /sdcard, but no access via cwm and "choose zip from sdcard". error: E: can't mount /sdcard/
if i list files via adb shell from /sdcard and /data there are no files.
can somebody help me?

one more info.
in adb shell, if i try to mount /data manually, i get following message:
[email protected]:/ # mount /data
mount /data
mount: mounting /dev/block/mmcblk0p8 on /data failed: Invalid argument
i assume that this blk device has no filesystem. but how can i format it manually?

ok... i solved it.
who want's to know how i solved:
i formated /data with ext4 via adb shell.
[email protected]:/system/bin # /system/bin/make_ext4fs /dev/block/mmcblk0p8
where /dev/block/mmcblk0p8 is my /data (according to the fstab)
after that i was able to mount /data !!!
i flashed cwm 5.5.0.4 again via odin, flashed (odin) stock rom (works now!)

It seems that I have a similar (if not exactly the same problem). Problem is, I'm not exactly tech savvy enough to
understand/execute your solution on my own.

Can you tell us how you go about formatting your SDCARD? I have a similar problem and can't mount E: data/ whenever I try TWRP or CWM recoveries on my p7300. Can you give us step by step or at least a link where to start. Sorry, I am not familiar with ADB.
Thanks for your support with this tab.

Try to install a new twrp recovery using the following instructions. That fixed it for me:

incomplete su binaries perhaps? I suggest flashing a su.zip file, being it from Chainfire's, or Koush's, it doesn't matter.

Unable to mount storage - failed to mount /data (no such device)

I just tried to clean-install OmniROM with TWRP-3.0 on my Xperia Z1 (6903 UB). I was on CM12 nightly, but my phone went soft-bricked. ): TWRP says:
Code:
Unable to mount storage
Failed to mount /data (no such device)
Any advice? Thanks!

As the error says: your /data partition is missing. You can't wipe something that isn't there!
Try these:
1. As an experiment, in case /data is corrupt: repair /data by tapping Wipe > /data > Repair filesystem and format to ext4. I had a similar error with my phone's /cache when I was dealing with an unstable KK build, but performing these steps fixed my issue. Your situation may be different...
2. Transfer a stable LP or KK ROM into a sdcard or phone and flash it. You may also sideload or push the zip through adb if you don't have an sdcard and OS to boot to, but have a working recovery; make sure you have the correct drivers installed on your computer. Depending on the kernel, you may or may not have recovery built in to your boot.img, so flash recovery through fastboot if needed.
3. Planning to return to Sony's default ROM?: Use flashtool to restore your phone to its factory state. Find proper FTF file through XDA and flash. Guide: http://forum.xda-developers.com/showthread.php?t=2428319
Hope my answer is clear enough! Good luck getting this sorted out!
