Hi @all!

I just 'tried' to root my ASUS Memopad FHD 10 16GB (WW-version).
I post here because I simply think that you guys at XDA are certainly the ones who know the solution, if there is one.

It seems as if the userdata+cache partitions are "destroyed" or something like that.

Having Android 4.3 it was not possible to flash the rooted system-image, so I first wanted to "downgrade fastboot" to the version from the "" firmware and then try again flashing the 4-7-3 firmware. But after flashing fastboot, when I tried wiping all data I got this:

fastboot erase system
fastboot erase cache
fastboot flash fastboot fastboot.img

fastboot -w
erasing 'userdata'...
OKAY [ 15.292s]
formatting 'userdata' partition...
Erase successful, but not automatically formatting.
File system type not supported.
OKAY [ 1.634s]
erasing 'cache'...
OKAY [ 3.607s]
formatting 'cache' partition...
Erase successful, but not automatically formatting.
File system type not supported.
OKAY [ 1.186s]
finished. total time: 21.729s

Since then I cannot format the partitions or userdata. Flashing the firmware 'supposedly' works (console output on PC says 'finished').
But after "fastboot flash update" is done the device restarts immediately, then
1. shows the android figure with opened hatch and a green progress bar
2. figure changes to one having a red triangle inside
3. reboot and then showing the ASUS bootscreen for like 10min.
4. The last step repeats like 4 times, then the android figure with red triangle appears again, then bootscreens again ... (endless loop)

So as you can see I cannot boot into android again. I think the problem lies with the "File system type not supported" but.

When I try to format directly I get:
fastboot format cache
formatting 'cache' partition...
Formatting is not supported for filesystem with type ''.
finished. total time: 2.303s

Does anyone know how I can fix this and reinstall any firmware?
My ideas were
- format the partitions to ext2/ext3 directly (there should be a way to specify the filesystem, right?)
- flash the userdata/cache partition with someone else's partition content
- use a custom-recovery for the tablet which does this - though I cannot find one anywhere

Thanks XDA! =)


Thanks to perpe and wakatu the problem has been solved by flashing the original recovery, as specified here:
