Umidigi f1 Fastboot problem

Marce95

I am trying to re-lock the bootload with fastboot but in the cmd I cannot see the device (in fastboot mode). I have installed the last USB driver and adb minimal 1.4.3 but nothing is showing up. Any solution?

- be sure to start the CMD window with admin privileg
- be sure to use an USB2 port (USB3 generates problems)
- be sure to try a different USB cable (that was my problem)
- be sure to allow USB debugging in Engineer mode and allow connection (on the mobile screen)
- run "adb devices" to check if your computer sees the mobile
- run "adb reboot bootloader", phone should restart in fastboot mode
- run "fastboot devices". If you get a result all is well and you can run "fastboot flashing lock"
