How to root the Fairphone 3?

Hi all,

the solution above does not seem to work. I don’t get a pop-up asking for permission to allow USB debugging.

I installed TWRP and LOS 17.1. I unlocked the phone, flashed Magisk en locked the phone again. The last step was apparently the the problem. I did a factory reset. Got back to Google. Then I was able to manage to unlock the phone again via fastboot and flash TWRP and LOS again. I could do this while ADB said I have an unauthorized phone.

Is the above to say that my phone is bricked? I mean, I have a working FP3 (with LOS) installed.

The only problem is that I am not able to connect the phone via adb. I tried a lot to fix the problem via information on several threads of xda-developers and stackoverflow.

And if there is no solution for this, please let me know!!

btw my bootloader is unlocked

btw 2. I tried to install Magisk in this way:

But that didn’t work either, because I got stuck at step 8. 'And finally install MagiskManager-v7.5.1.apk
