is it possible somehow to cleare the partitions "deeper" then it's possible with the build in format command inside CWM?
I tried the fastboot erase (system, data, boot) with the result "permission denied" also.
The problem is the Moto G got messed up during the update to 4.4.
Since that moment the Moto G won't boot up with any stock Rom i flashed and i checked up many, many different stock roms (4.3 and 4.4.2).
It is possible to access recovery. (only CWM-swipe is working, CWM-touch, TWRP or the stock recovery won't boot) (Somehow TWRP booted once, but never again...) Sometimes i even can't access CWM-swipe, than I have to erase userdata and cache inside bootloader.
The other thing is it was possible to boot up the G with the Lego Rom, but it rebooted very often (30secs, 1min, 10secs....)
At this moment even that doesn't work it's getting stuck inside the bootlogo like every other custom rom i tried (Slim, CM11).
This behaviour makes me belief that things must be messed up depper inside.
I like to wipe everything!
