I received my FP 2 a few days ago and spent some time toying with it in the “native” Fairphone OS. Then I switched to Fairphone Open and continued toying with it.
Now I would like to go back to the Fairphone OS (and probably switch OS a few more times before making a decision; but that is out-of-topic). The method 1 (using the built in updater) on this page https://code.fairphone.com/projects/fp-osos/user/fairphone-open-source-os-going-back.html is not working (the updater tries to update the open OS to open OS, not to fairphone OS).
I do not consider myself an advanced user. I installed some free applications from various sources. I did not root the device. The most avanced action I performed was a reset to factory settings.
So before trying method 2 ( Manually installing the OTA package), I would like to know: is it risky? or maybe if it fails, I will just be sent back to my current situation? or something else can solve my problem?
Any advice is welcome… I do not care if I loose some data (as long as I do not break the device), but I am not willing to spend too many hours doing something I do not understand.
