Ok... Finally I killed my Jolla C
After some times of disassembling, and restore from Recovery mode, the touch screen stopped to react... It go to the page where user should choose the language and I can't do nothing...
I disassembled phone again, but didn't find something not connected or damaged... Probably I killed my phone some how...
I returned to use the Jolla 1 for now and waiting for official Sony Experia with full sailfish os.

End of story...
