Unable to take backup using ClockworkMod in Mid9742

[ashok_fun123]

Hi there, I have installed Clockmod recovery as suggested in this thread and I could able to see all CM options in recovery mode. When I try to take backup, Boot img and recovery img were successful, but it failed to take backup on System. Can someone help me on this. Thanks, Ashok

First how and what did you do? How did you root and installed CM.

What does it say? Do you have enough of storage ?

The complete story is in the following thread: http://www.androidtablets.net/forum...removed-execute-permission-system-folder.html . In short, he screwed his tablet up, used LiveSuite to try and fix it, then installed CWM on top of LiveSuite. I had already recommended to him to exchange the tablet, because there's no way this tablet will ever function 100% correctly after everything that has been done to it.

Coby wasn't agreed to replace my tablet, since its out of warranty and I went with the wrong option of installing it from Livesuite and suffering now, since its failing to take backup of system, is there is way to fix it, might be odd knowing the system is broken and asking for fix recommendation.

just a thought, can I use someone recovery data and restore it back, is that viable option is CWM? I'm not a android/Linux guy, just searching for options

Just used show log options in Advanced Option in CWM. Please refer below,

I: Checking for extendedcommmand..
I: Skipping execution of extendedcommmand, file not found…
SD Card Free space :27744MB
Backing up boot image..
Backing up recovery image..
Backing up system..
tar: write error : I/O error
log might help for experts Thanks,Ashok

The log simply says tar can't write to your device, so it is unable to make a backup, device must allow write permission and be large enough to hold the backup.
Most likely you will run into more problems with your tablet, The problems most likely will be due to livesuite, The livesuite image people are using came from elf which is a completely different device than the Coby. So there will always be some problems with any tablet that has used an elf livesuite image.

Resolved the issue by unmounting external SD, initiated backup process in SD card and succeeded . Any idea why isn't backing up in external SD card?

Most likely the recovery isn't identifying your sdcard, it's looking in a different place for your sdcard. You would need to compare the vold.fstab to the recovery recovery.fstab for sdcard

Your micro sdcard is /devices/virtual/block/nandi The recovery most likely is looking for micro sdcard at /dev/block/nandk

what recovery are you using?

 

[ashok_fun123]

i'm using v5.5.0.4, which is posted in this thread.
