Does anyone know how I can unlock #oneplus 7 Pros bootloader. I want to switch to #lineageos but am failing at that step during the install
Things I have tried so far:
-enable OEM unlock in developer settings and then using fastboot to unlock it. That fails with an error message (known issue on android 12, other threads reccomens downgrading to 11).
- using an inoffical firehose client (https://github.com/bkerler/edl). I don't know what the issue there was, there was no relevant error in the output, even in debugging mode (though I suspect it is the same issue as above).
Things I have tried to downgrade to Android 11:
-using the official rollback packeges. Sadly the links on tge official thread (https://community.oneplus.com/thread/1181167844348919809) are dead and I cant find the rollback packages anywhere else
- using the unbrick tools (https://xdaforums.com/t/op7pro-latest-oos-11-0-5-1-gm21aa-gm21ba-collection-of-unbrick-tools.3956595/). Since I don't have a windows PC, I tried it on a friends laptop where it just didn't work without a clear error message. I then set up a new win 11 VM. There I couldn't install the required drivers (super generic errror message, something like path not found but without specifying the path).
