[G 2014 Q&A, Help & Troubleshooting] cxxxx:
I was now able to download the original firmware.

But...it's the same :'(

I did every step to reinstall stock firmware. No error-messages, neither on console nor on device, everything seems to be fine.

But when I finally reboot, the device again asks for my encryption PIN and will fail to startup!

I still cannot wipe my userdata, still cannot flash a custom recovery...nothing. It's just a ******* brick.

I found one interesting error:

C:\Users\cxx\Programme\adb-1.0.32>fastboot -w

How can I manually reformat my partitions in internal storage or how can I force automatically formatting?
