1. By some reason none of flashed TWRP's request the unlock pattern now (earlier it was requested and file structure was ok to copy the ROM) for this reason on the sdcard there are files and folders with random letters and can not copy the ROM in it. What is that and what can be do to be able to copy the ROM?

2. How can I install the ROM with USB-OTG device, I have not found a description to do that
3. I would like to avoid clean install, because after several try i could install the previous ROM with format data only and spent two days with restoring.
