Forgotten alternative FIX when fastboot bootloader not detected

[yvmuell]

Still the easiest way in I think in 99% of the cases.

If the FP is not recognized in Fastboot:
It can be the cable or USB port, but most of the time it is a fastboot driver problem (on Windows). To update the driver: connect the FP in fastboot mode to the PC, go to Windows Updates, check for updates manually, go to Optional Updates and Drivers and install everything regarding Google/Bootloader (e.g. Kedacom/LeMobile).
