[Q] My UbiSlate 7C+ always boot into CWM recovery & can not mount /system /data - General Questions and Answers

Whenever I boot my device, I get to see the Datawind start screen and that's where it stays. Nothing happens.
When I boot my device with the volume button pressed, I get to see the menu of CWM based recovery v6.0.1.5.
Immediately it gives errors:
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
If I try to wipe the cache partition I get:
--Wiping cache...
Formatting /cache...
E:format_volume: make_extf4fs failed on /dev/block/nandh
Cache wipe complete.
and for ----- wiping data...
Formatting /data...
E:format_volume: make_extf4fs failed on /dev/block/nande
data wipe complete.
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
Is there a standard ROM that I can download and install?
I have also used adb
It did not help.
And I cannot find a ROM that I know will work for my Tab.
Basically I want my Tab to boot again and I have no clue what I need to do.
Can you (or someone else) please help?
Many thanks!

[Q] My Fascinate will not turn on! Please help!!

Last night, I was looking at an article I found on Facebook. I was reading the article, and my phone locked up (my phone has a tendency to freeze when I am using any web browser.) So I took out the battery like I do any other time that this happens. I put it back in after two or three seconds. I then turned it on. It is fine until the boot animation starts up. Then it will stay at the boot animation forever. I did not download anything before it happened. The phone is rooted. I have already tried wiping the cache partition and taking out the SD card. Neither worked. Would a factory reset fix the problem, and would it erase the root on my phone. By the way, when I booted in recovery and tried wiping the cache partition, I got the following.
ClockworkMod Recovery v4.0.1.0

[Q] bootloop plus a problem with the cache

My phone somehow got stuck in a boot loop and I can't fix it. I don't know what to do. I cant get pass the start up animation no matter what I do.
I've tried the fast boot commands to flash and keep getting the error (i dont really know alot about flashing and never done it before but the that what i found suggested in the web..)
FAILED < remote: flash write failure >
I've tried the flash-all.bat file, but the lock state goes back to LOCKED when it reboots the device and I get the error
not supported on lock device
I can unlock the device when I type fastboot oem unlock, but if the device is restarted it goes back to LOCKED.
I've tried recovery mode and I see the below statements:
E:failed to mount /cache (Invalid argument)
E:Can't mount /ache/recovery/log
E:Can't open /ache/recovery/log
E:failed to mount /cache (Invalid argument)

It sounds like your emmc is fried. not being able to lock/unlock your bootloader is a classic symptom
