with the phone in fastboot mode, I was able to update the drivers. I then tried this [HOWTO] a Clear Guide to install "IMG-e-builds" when /e/ web installer fails
but when I enter the command fastboot flashing unlock_critical, it says Failed (remote: device already : unlocked) fastboot: error: command failed
Can I conclude that my device is unlocked, proceed to the next step and install the e/os ?
Thanks !
