hibernick, Jul 8, 2016 : Hi guys, I have the following configuration: the phone is onepluse one, stock recovery, bootloader is locked, USB debugging is off OS - ubuntu 15.10 adb version - the latest update.zip - signed zip from cygn.com COS13.1 the latest OTA update. The phone boots but right after booting I can not unlock the screen. When I swipe the screen It just hangs and goes to reboot. So I can not activate developer options to enable USB debugging. when I set phone to adb sideload mode: $adb devises 89xxxxx sideload but $adb sideload update.zip error: protocol error (no status) Does anybody know why It doesn't work?
