If the system is not 5.1.1 or 6.0.1 or CM CM 13.0 or 14.1 , you will need to re-brush firmware.
The following is a manual brush firmware steps: the firmware compressed extracted the platform-tools folder, then cmd enter the command execution path respectively
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cache cache.img
fastboot flash vendor vendor.img
fastboot erase userdata
fastboot flash userdata userdata.img
After completion of the restart, wait slightly longer to enter the Developer options open USB Debugging, and then painted recovery, supersu, nethunter etc.
PS：
In case 32g dryer, brushing nethunter only 16g case, it is necessary to repeat the above operation of the original brush, after the completion of reboot, follow the following path settings> backup & reset> factory data reset> reset phone> erase everything ( the path only for the 6.0.1 system, other systems may be slightly different, but the idea is formatted Internal storage)
