Stuck on fastboot during /e/ installation after rooting the phone and locking the bootloader

Welcome to the community forum.
I edited the topic title to better reflect the actual situation.

@Exstramonium

I followed these steps How to root the Fairphone 3?

A bit further in this topic …

How to root the Fairphone 3?

Even though it is not listed in your guide, I assume the bootloader still has to be unlocked for this?

How to root the Fairphone 3?

Yes, I had unlocked my Fairphone 3 from the factory so I forgot to include this step. Its basically as simple as booting into fastboot and running: ‘fastboot oem unlock’ (THIS WILL ERASE ALL DATA)

@Jona

It is impossible to lock the bootloader, again after installing magisk. Am I right?

@lost_geographer

I corrupted the system by locking back the bootloader (sometimes I do stupid things). But it’s quite easy to solve this problem : just flash everything back, following again the install instructions of /e/ .

@Exstramonium

so I reboot to fastboot mode and took the installation’s step for /e/ again

And you unlocked the bootloader again for this?
