I just bought a fairphone 3+, and I want to install e/OS, I followed all the instruction and at this step I had a problem :
“unlock the bootloader and start again your phone with fastboot mode”
“chose to unlock the bootloader with the volume button”
“press enter to confirm”
“enter the option menu with the volume button”
at this step my phone stopped, the screen is black. I can’t start the phone normaly or with the fastboot…
Can anyone help me?
I add, that the phone was new, without any account or data on it.
