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. I don’t know what the issue 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 the official thread are dead and I cant find the rollback packages anywhere else
- using the unbrick tools. 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).
I personally wouldn’t downgrade to Android 11 since the Lineage Installation Instructions clearly state you need to be on 12.
If there is an error during unlocking the bootloader, I would get in touch with the people from LineageOS - scroll to the end of the same page “Get assistance”.
Sorry I wasn’t clear on this, I planned on downgrading, unlocjing the bootloader and then updating to 12 again, as that apperently worked for others in the past.
