Installing eOS on Fairphone 3

[AnotherElk]

I downloaded the necessary files and installed “Minimal ADB and Fastboot” on my PC (Windows 10).

This might work, but the install guide recommends to use the current Android SDK Platform Tools.

However, I got stuck with the command: “fastboot flash recovery twrp-3.4.0-0-FP3.img”. I got: “FAILED (remote: partition table doesn’t exist)”.

I don’t know why that’s in the install guide for the Fairphone 3/3+, this is an error, it doesn’t work that way on A/B devices like the Fairphone 3/3+.
Just ignore the “Installing a custom recovery” section, the guide doesn’t use TWRP at all after this.

Seems like a rather old error, too …

TWRP in install instructions for the FP3?

I just wanted to point someone to the install instructions for the Fairphone 3 when I noticed that is has a section about flashing TWRP. IIRC that wasn’t there when and last looked at that page. And in fact TWRP is not actually used in the instructions. This looks like an error to me (and wouldn’t even work as the FP3 has no recovery partition).

I came across the recommendation not to install TWRP as this would make OTA updates impossible in the future.

That’s true for Fairphone OS, not for /e/.
On A/B devices there is no recovery partition to flash a recovery image to. Instead installing a custom recovery like TWRP is done by altering the boot partition. The Fairphone OS updater doesn’t OTA update in case it detects altered partitions, /e/ will just restore its own boot partition including its own recovery when doing an OTA update (so an installed TWRP would be gone).
