imei blank...

this is what happened earlier...
i tried rooting my phone on 2.3.5 then found out i needed 2.3.3 max to root, so i tried flashing 2.3.3 to my phone, something went wrong and now after several attepths at restoring it it just boot cycles. i can get into download mode no problem, but it doesnt matter what i flash it tells me it cant mount efs or dbdata. is there a way to fix this or do i need to send my phone off to get it repaired?
melli.
could reflashing the efs sort this? if so where can i download it? cause i can't find the efs.rfs anywhere...

ok i have now got my phone working again with a few hours tinkering thru heimdall. but now i have no imei number its just blank... any ideas? i have tried every rooting method ive managed to find on here so far none work so i can't edit the stuff in the efs partioion anyway. any other ideas???
melli.
now i have the phone working but have a blank imei and cant find any way to restore it.
when i go into recovery mode i still get:
E:failed to mount /efs (invalid argument)
E:failed to mount /efs (invalid argument)
E:check_selective_file:can't mount /efs
-- Copying media files...
Succewwfully copied media files.
-- Appling Multi-CSC...
E:failed to mount /efs (invalid argument)
E:multi_csc:Can't mount /efs
Multi-csc applied failed.
so it seems i still have an invalid efs partition. any idea how i can fix this? ive tried loads of rooting methods and none work... so i cant even copy from another efs partition on another phone.

TWRP: "E:failed to mount /sdcard (Invalid argument)"

I formatted my Kindle Fire using my Mac computer as a Mac OS Extended (Journaled) drive. Unfortunately, when I tried installing a ROM on my Kindle, it did not succeed. So, I wiped the cache, Dalvik cache, and system (oops), and performed a factory reset. However, when I attempted to wipe the external storage, it Failed. The error message stated:
Code:
E:failed to mount /sdcard (Invalid Argument)
E:tw_format_rmfr: failed to mount "/sdcard"
* Verifying filesystems...
* Verifying partition sizes...
E:Unable to mount '/sdcard' (tw_mount)
E:Unable to mount '/sdcard' (tw_mount)
E:failed to mount /sdcard (Invalid Argument)
E:failed to mount /sdcard (Invalid Argument)
E:failed to mount /sdcard (Invalid Argument)
Additionally, the Kindle Fire has no OS installed (since I wiped to system), and the ADB shell does not recognize my device. Any ideas on what to do? Thanks to anyone who responds!

Boot freeze and partitions lost

Hi,
my german N7100 one sad day rebooted just to the Samsung logo and froze.
After some research i found Heimdall and jOdin and managed to flash TWRP 3.3.1-0 as recovery.
Booted into that, looked around and found on tapping the menu icon:
Code:
Failed to mount '/cache' (Invalid argument)
E:primary block device '/dev/block/mmcblk0p16' for mount point /data is not present!
Failed to mount '/data' (Invalid argument)
Unable to recreate /data/media folder.
Updating partition details...
Failed to mount '/efs' (Invalid argument)
Failed to mount '/cache' (Invalid argument)
Failed to mount '/system' (Invalid argument)
Failed to mount '/data' (Invalid argument)
...done
Unable to mount storage
Failed to mount '/data' (Invalid argument)
Full SELinux support is present
E:
Unable to mount /data/media/TWRP/.twrps
MTP Enabled
ADB was and is enabled.
Flashing a stock ROM with jOdin first complained about a missing PIT file, then proceeded getting one from the phone, then did the flashing and reported PASS.
Didn't change a thing, though, the phone still didn't boot further, and TWRP reported the same as before.
adb shell
works and i looked around in the phone; i found
/dev/block/mmcblk0
and
/dev/block/mmcblk0p1,
both readable by less, but no other mmcblk* were there.
The phone has a MicroSD card inserted, which isn't listed in /dev or /dev/block, although TWRP can write the system logs "successfully" to it.
Right now, i can't check the contents without a MicroSD adapter.
I looked around here and found nothing quite similar, therefore this new thread.
Help, please?

maybe emmc dead or what?
