I tried to follow this manual and it was alright until article 12. When I enter “fastboot devices” command my device isn’t on the list. The command “fastboot help” works. If course my phone is on the list after “adb devices” command and it enters into fastboot more after “adb reboot bootloader” command.
Does it mean I have correctly installed drivers on my computer or i need some specific driver especially for fastboot mode?
