Building LineageOS for FP4

[oli.sax]

@Aaanze

I would gladly hear some tricks about efficently going to fastboot/recovery/bootloader when device wont boot to OS and bootloader unlocked warning seems to somehow mess with the vol down + power combination.
I mean I’m pressing the vol down + power buttons and no matter what it either tries to boot and get stuck on Fairphone logo, or shutdowns. I managed to get to it earlier but don’t quite understand how I did it.

Don’t press the power button, but instead maintain one of the volume buttons and then connect the USB-C cable to your computer. Your FP4 will be in:

• volume down + cable : fastboot mode,
• volume up + cable : Android recovery
