I've had a few problems installing ROMs recently; boot loops, errors etc. And then when I try to restore my back-up, having wiped everything - /system, /data, /cache, /(int)sd_card, it reports a failure to restore the /data. But when I restart my phone, it's still how I left it: apps, phonebook, messages are still there and still work. I can read and write to the /data partition with ES or Xplore.
It first occurred using CWM but it did the same thing with TWRP, as well. TWRP reports 'failed to mount data', CWM, in Mounts & Storage, says "unmount /data" but nothing happens when I click on it. It just flashes and stays on 'unmount' option.
Backup data from both recoveries is fine. It's the right size and if I copy it to my PC and unpack it, everything is there so recovery has no problem reading the /data partition. Just writing to it. Or formatting it.
Any clues as to what's causing this would be greatly appreciated.
I'm running V20E Android 4.1.2 by szymel.

I rooted and installed CM7 on my SGS i9000B about 1 month ago. Everything was going fine and I was in love with my phone.
This afternoon, suddenly and with no apparent reason, it started giving me infinite "Force Close" messages to all apps I tried to open, making the phone pretty useless. Whe this happened I tried repairing permission from within Rom Maanger but the problem persisted. So I booted in recovery mode (Clockwork Mod Recovery) and tried fixing permissions there, but force closing problem was still there.
I had an Nand backup from the day I installed CM7. So I went to recovery mode again and tried restoring the backup, but it gave me an error (I believe it was somwthing related to disk space, but I'm not sure about that). So I did another backup (just in case) and tried to reboot the phone to try restoring backup again.
The problem is, now I can't get to recovery mode again. When I rebooted I was not able to go back to recovery mode anymore. I am still able to get to Download mode though. So I was thinking about flashing some rom/bootloader or something back in from Odin, but as I have no experience doing this, I believe it's safer to ask for help here before doing anything to the phone.
I believe it's not bricked yet, since I can still get to download mode.
Can anyone give me some detailed info about what I should do?
Do flash Kernel one more and,
Do root again and try that working.
If it happend again, wipe dalvik-cache and after your device is rebooted, try again in CWM.

Sorry but I have very little experience with this and I want to be sure about what I'm supposed to do. What do you mean by flash kernel again? Is it flashing CyanogenMod 7 again via Odin?
I flashed the kernel again using Odin. Used the same file that I used before (when I fisrt rooted the phone a month ago - speedmod k13C). Now I can get into Recovery Mode.
But now I have a different problem. I tried to do a nandroid restore (backup and restore - restore ALL) but I have some errors related to mounting errors:
Code:
Checking MD5 sums...
Restoring system...
E:Can't mount /dev/block/st19 to /system with parameters auto llw.check=no
(File exists)
Error mounting /system/!
Skipping format...
E:Can't mount /dev/block/st19 to /system with parameters auto llw.check=no
(File exists)
Can't mount /system/!
I have no idea what that means.
Any help?
While searching for help on this error I found some people saying that flashing stock rom back intro phone could solve the problem. So this was what I did. Flashed stock samsung rom back i using Odin but when phone rebooted the following error appeared:
Android system recovery <3e>
Samsung Recovery Utils
- for BML -
[some recovery options]
update media, please wait
E:Can't mount /dev/block/st110
(Invalid argument)
E:copy_dbdata_media:Can't mount DBDATA:
So I have a very similar error - "can't mount /dev/block/SOMEFILE". It looks to me like a problem with the internal sd card. What do you guys think?
Solved
I could solve the problem using the method described in this thread.

My tab froze and when I rebooted it, I get a black screen right after the AOKP logo. It just sits there forever. I can boot recovery.
My story is below, but I think my question is: How can I format the partitions, because I think /data is corrupt?
Story:
I can boot recovery, and I wiped everything, then tried adb pushing a rom to the /sdcard. That's when things got weird...
adb push failed, so I rebooted and noticed that /data wasn't mounted. (/sdcard is just a symlink to /data/media)
I mounted /data from recovery and tried to push the ROM file again. This time I got some I/O errors on the push. I also noticed that in an adb shell, the /data partition would sometimes unmount by itself, and threw disk errors when copying files around. All other partitions seem to work fine.
So I deleted everything in /data/media, formatted /data, and tried again. This time I could adb push the ROM. I installed the ROM, but I still get the same freeze after AOKP logo.

I would say you need to ODIN your TAB:
Use this:

I just accidentally wiped my internal storage, now TWRP can't see it or mount it? In the process, I wiped my external SD too (I swear, I'm not a NoOb).....
I've tried installing some ROMs via TWRP, but it errors out and say's: Failed to mount '/data' (invalid argument).
HELP?
[UPDATE]
Finally got a ROM to install....

99% of the time that's how things go ?. As long as you can into the bootloader there's a next step.
Glad you're good to go
Missed your post on my earlier run through. I would of suggested formatting data from within twrp. This is destructive in that it wipes both data and internal storage, but should resolve your issue.
Running latest twrp.
Big problems.
Can't backup, mount, wipe /data partition or access internal storage. Although formatting /data temporarily fixes the issue, as soon as I install A ROM within a few days when I try to backup I can't backup /data as its not mountable.
Any ideas?
Follow this guide.
It's not in english, but I can guarantee you 100% that it works.

So I finally unbricked and booted the stock rom. Now im trying to reroot the thing.
When I go to format/unencrypt in TWRP I get ERROR 255 -t 0 /dev/block/mmcblk0p54
Is my data partition permanently corrupted? I know that partition exists inside /data.
I've already tried to manually format /data, repairing it, changing it from f2fs to ext4 and back. All failed.
I'm have a similar problem. I cannot mount anything thru twrp. System, data, cache, can't do a wipe all fail. I've tried changing file system the back but it fails. I was able to mount my sdcard and start the recovery but.... its. Been "working" for and hour with no process increase. I'm wondering if I can force a fix partition thru adb sideload. Or... how can I decrypt it. Also the internal storage registers as 0 out of 0, same as /data
