[HOW-TO] Flash /e/-OS on Fairphone 3 using Debian based GNU/Linux

I’ve heard of the a/b fix but according to this, that might not go too well.

The A/B “Fix” doesn’t do anything with any partition or with user data, it just changes the OS slot to boot.

Fairphone 3 : Update

Been hit by the nasty update bug. Did the fastboot --set-active=b and was allowed to use the phone again. Thx for the tip. Hth,

The case you linked to needs clarification on what exactly the user did.

From what I understand, there’s a total of 6 partitions that the FP3 houses.

There are several more.

@meetowl

Which one of these houses my data, and what do I not flash to keep my data?

The data partition which has your data is called userdata, and because it has your data an update doesn’t flash or wipe it. The wiping of it is part of the instructions of an initial manual install, though.
