Required

Before start very important is to disable windows drivers signature enforcement in windows (google how to)

How to

Note

  • For those getting qusb_bulk ( and reconnecting ) brick.
    • Connect phone with PC and then press all three volume up, down and power button at same time and hold like 15-20 sec, edl normal will appear.
    • Or press and hold power button 15-20 sec until phone start, as soon as phone start release power button then immediately press and hold volume up to enter recovery mode. In recovery mode chose “power off device” and turn off. Now when device is turned off press and hold at same time volume up and volume down, while holding connect device with PC. Now device will be in normal EDL mode. Now go to device manager and uninstall drivers qusb__bulk , install Qualcomm drivers above (maybe u will need restart pc or reconnecting phone, just disconnect and hold again volume up and down, connect and normal EDL 9008 should be installed ) after that use QFIL. Tested by me.
  • If u are bricked and want to unbrick without losing data, use same version or higher EDL rom over current one u are right now. Example if u brick on 14.0.11 use EDL rom 14.0.11 or higher to unbrick to save data.
  • If u want to convert rom, or flash downgrade data will be lost. In some scenarios white screen will appear with message fs_mgr_mount_all – from recovery menu u need factory reset and boot normal. If u get bootloop or stuck on Nubia logo-boot to recovery by pressing volume up when boot start and facory reset there.
