Hi Everyone,

For some reason, TWRP is not able to format /Data.
It keeps saying "failed to mount /data (Device or resource busy)".
This doesn't prevent me from updating the ROM to 4.4.2-21.
However, once updated it keeps on booting over-and-over.

Is there a way to - sort-of - a forced format of the internal flash.
Or at least the /data partition as it seems to be corrept.


Thanks - Will

Hi,
With twrp use the wipe menu for installing kk 4.4.2
Wipe cache-dalvik cache-data-system-internal storage (if you need a complete clean install), after install menu, flash the rom and the gapps, return to wipe menu, wipe cache and dalvik cache again.reboot.you`ll run on the new rom
(Ps : don't used mount sd and format menu).

Thanks for the (quick) response.
I'm coming from 4.4.2-19. However, on previous occasions I was able to upgrade without going through a clean install.
So I tried the same this time with 4.4.2-21. However, as it stands, this release tends to end up in an ever on-going boot sequence.
Even a clean install or going back to the previous version (4.4.2-19) doesn't work.

Compared to previous installs, the only difference I can see is an error stating that /data can not be wiped.

Any thoughts on this behavior?


Thanks - Will

Hi, which release of TWRP do you use ? in 2.6.3.0 and lower release, on wipe menu you have an advanced wipe menu, go on it select format and type data, this will format data partition

Tried formatting the data partition. It comes back with "failed" - no explanation.

Any other suggestion?
