I’m currently running Lineage OS 15.1 but I’m having some trouble and I will maybe change back to Fairphone OS.
Last weeks, I have download several Lineage OS from https://download.lineage.microg.org/FP2/
I boot on TWRP and I successfully install the image without format data partition.
After flashing, I retreived all my stuff and I was happy.
My question is the following : can I install last Fairphone OS with the same process without lost all my stuff (apps, setting…) ?
