OEM unlocking on Fairphone 3 does not work

This is the “Fairphone Unlock page” Bootloader Unlocking Code for Fairphone - Fairphone … it contains full instructions. I am not certain, but I thought that this was a one time event. I don’t think you want to be doing this with easy installer, I think that you need to carefully sort out –

  • has it been done already?
  • or is it still to do? (I do not believe this is a job for easy installer [1])

While the following three are not perhaps fully discrete, we have to be careful about using the right term for each.

  1. The Fairphone unlock process.
  2. OEM unlocking. (Notice how the Fairphone Unlock depends on Developer options → Enable OEM unlocking)
  3. Locking and unlocking the Bootloader.

I didn’t realise that the tutorial I already linked, leaves you to sort out the The Fairphone unlock process yourself. However it does cover the other 2 locks fully.

Maybe you are drawing the wrong conclusions from Easy Installer failure. You could look for logs.

This is the Official install page Install /e/OS on a Fairphone FP3/3+ - “FP3”.
