I just got my Fairphone 4 yesterday and I wanted to flash it with /e/ OS image so I followed the install tutorial Install /e/ on a Fairphone FP4 - “FP4”
I enabled developers options, unlocked oem and allowed usb debugging. I installed android sdk followwing these instruction Installing adb and fastboot on a Linux PC.
I can see my device using
and I can reboot the phone in bootloader mode with
adb reboot bootloader
When in bootloader, I see my devices serial number and device state is locked,however, when I type
I get nothing. When I try
fastboot flashing unlock
I get “waiting for any device”
If I go to recovery mode and fastboot devices, I see my device and when I do “fastboot flashing unlock” I get the error “flashing unlock unrecognized command”.
Both my adb and fastboot version is 126.96.36.19953317. I am using Ubuntu 20.04. Anyone has got any idea how to resolve this?
I managed to solve this just by connecting the phone to a different USB slot and then fastboot seems to work.
