[Xperia Z1 Compact Q&A, Help & Troubleshooting] ULT][MO:
Hi guys, I flashed CM 12.1 with CM recovery on my device one month ago then I tried to install CWM-TWRP dual

recovery to make a nandroid system backup:

1- I tried to install via CM recovery and I've obtained this result:

Finding update package...

Opening update package...

Verifying update package...

E:footer is wrong

E: signature verification failed

Installation aborted

The CM recovery seems to install only cm12.1 new releases and gapps. Same result installing any other recovery, except flashing via fastboot.

Infact I flashed "Z1c_DooMLoRD_AdvStkKernel_FW-757_v04" (CWM) and worked fine, so I made all wipe and tried a clean

install of CM 12 obviously without CM recovery, but when I power on the device the CWM has been removed and the fu**in'

CM recovery it's back again!!!

2- I tried to flash a new fw via flashtool and the result was this:
