Ok, this is a tricky one, but after some trial and error, I was able to get my FP4 to boot without any button presses. The process is as follows:
- Remove the battery of your phone and reinsert it, in order for the phone to 100% completely have shut down
- Connect a charging cable to the phone and be ready, to disconnect it very quickly
- Once display shows the Fairphone logo, immediately disconnect your charger, even before the phone vibrates
- If you were fast enough, the phone should now boot normally instead of only displaying the charging screen
Here’s a video of me doing it. Unfortunately I only had a bad webcam to record, but it should make the process very clear: Watch demo | Streamable
