[Q] Splash screen lock up & mounting issues

Hi folks,
I rooted my GT-P7300 and upgraded it to Jellybean (cm-10-20120804-UNOFFICIAL-p5) without problem (besides picasa sync not working), I noticed there was a later version cm-10-20120808-UNOFFICIAL-p5 and that's when it all went wrong
Now my tab locks up at the samsung galaxy tab splash screen.
I can go in recovery mode (running CWM v5.5.0.4) - Odin seems to be OK as this is how I installed CWM recovery
Wiping dada gives me the following
--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 tried moving back to stock recovery, but it has problems from the get go :
-- updating application...
E:failed to mount /system (invalid argument)
E:install_application_for_customer:Cant mount /system
copy application failed
-- appling Multi-CSC...
E:failed to mount /system (invalid argument)
E:install_application_for_customer:Cant mount /system
E:failed to mount /system (invalid argument)
E:multi_csc:cant mount /system
I'm kindda stuck now. so if anyone has somme smart suggestion...

fixed

You'll have to try flashing stock again. Chances are that your internal memory died though.

Yeah, I got it. My Internal memory died then I have to run OS on External Card. Also by the way it helps my old Captivate. :good:

Data recovery, how to mount messed up /data - Internal SD - sda25 in Recovery/ADB

Hi:
I've messed up my Note 9 pretty bad, such that no partitions mount in TWRP except cache - I'll need to do a data wipe, but I need to save data that I have in the Internal SD.
I've discovered via fdisk in TWRP that the media part - the Internal SD is partition sda25 - however can
t mount it in the terminal through a simple: mount /dev/block/sda25 /mnt
I get an error: mount failed: Invalid argument
I've tried: mount -t sdcardfs /dev/block/sda25 /mnt
This gives me also an error: mount failed: Not a directory
Mounting with -t vfat or exfat gives the Invalid argument error.
Anyone can help me with how to mount it, so that I may copy data off of it manually? I don't want to lose it. Many thanks.

cant you simply wipe the affected partitions(except data of course)? then flash a rom?
have you tried;
mount /sys/block/sda25 /mydata
or
mount /dev/block/sda25 /mydata
or
adb
mount -o rw /dev/block/sda25/data /mydata
in both cases /mydata is just the mount point so I believe it can simply be called what ever you want including just /data
have you read:

edit:
by any chance when you first flashed twrp, did you forget to format data?
if yes then flash back stock AP file(original phone's firmware) in Odin AP slot only and you should be good to go.( you shouldn't loose any files in internal storage)
