Sorry, I am totally new here. Got my FF3, wanted to install LineageOS, found a great looking guide how to do it and failed.
I followed this guide:
Step 4 I followed through but could not get the fastboot oem unlock.
FAILED (remote: oem unlock is not allowed)` or command not found
(fastboot was found, but not what came afterwards)
But there was a hint in the internet how to do this without OEM Unlock.
That was step 4 in chapter 4.
And then I failed.
Step 5 I did not really get.
I could see the bootloader is unlocked.
So I thought I chose the correct line and continued with chapter 5.
I downloaded the mentioned files.
But step 3 Boot your FP3 into the bootloader I did not understand what to do. I thought I was in bootloader.
And from here nothing works anymore.
I get a screen on the phone in small small fonts telling me that it cant load android system
Try again or factory reset.
All commands I issue in the terminal fail.
adb devices does not recognize the device.
The list is empty.
I am lost.
