Im trying to get calyxOS or /e/OS on my fairphone 4 but whatever I try, my bootloader wont switch to ‘unlocked’. I tried to ADB it, but i cant use ./fastboot for some unknown reason. I am using a mac, and also tried installing it by using the /e/OS easy installer but that also gave an error at ‘can not get the security patch level’.
OEM is unlocked, ADB debugging is on. Only fastboot stays on ‘unlocked’ in my bootloader.
Thanks in advance!
What means “can’t use” here? Does using “fastboot” give you an error?
There have been reports on the forum about adb working and fastboot not working and I think sometimes it helped to use different USB cables or USB ports…
Maybe you have another computer (linux, windows) too, to try it out with that?
Yes! I read that i could switch computer or cable. I have definately tried different cables and usb-c ports, but that did not help. Also i tried using parallels desktop since i only own a mac computer, but sadly that did not work either.
You haven’t answered my question regarding the error when using fastboot.
So what happens when you have your usb connected FP4 in bootloader and execute fastboot devices?
Don’t know about Mac, but in Linux it can also help to use sudo fastboot devices.
When I type “cd ” , then '“./fastboot” It already gives me “fastboot: usage: no command”. If i do “./adb” it starts running adb. When I type “fastboot devices” it says: “zsh: command not found: fastboot”. when i do “./fastboot devices” it gives me the location of platform tools with "% ".
About the sudo:
When I type ‘sudo fastboot devices’ it says “zsh: no such file or directory: ./sudo”
Now I tried with first typing “sudo cd ” and then using sudo adb it says command not found. When I type “sudo adb fastboot reboot bootloader” It says “zsh: no such file or directory: ./sudo”.
I’m not exactly sure about this output. Normally it should show an ID of your FP4.
Still it sounds like ./fastboot flashing unlock should be the correct command for unlocking your FP4 while it’s connected via USB to your Mac and while it’s in dic:fastboot mode.

as trying to unlock the phone with an usbc to usb adapter (and the fairphone cable then from usb to usbc) worked and there’s now a problem to install CalyxOS.
