Again tnx for the comments! I tried to get everything to put it into a step-by-step procedure to be sure. Right now I’ve got FP OS Open 16.07.1 on my phone. I don’t have any personal information, like contacts, photos or apps I want to keep. My phone contains primarely the apps from the FP OS Open. That leads to the next questions:
1a. Do I need to backup in this case? I suppose that it’s not nessecary to backup for the apps which come along with FP OS Open, cause Lineage will provide for the most basic apps and if not I can download apps from F-Droid for example.
1b. If I don’t need to backup to keep personal information etc, do I still to backup to have an image of my current system to be able to go back?
1c. If I do need to backup, can I do this by using the system option ‘Make a backup and reset’ on OS Open?
1d. If 1c is ‘yes’ do I need to put the backup on my computer or can I put it on a sd-card in my phone?
1e. If I have to put the backup on my computer, do I have to download and install Android Studio on my computer first?
Further on I understood that, if I do need to backup, I need to root my phone to be able to make a backup with Titanium. When I don’t need to do a backup with Titanium, I am now confronted with the next question whether I actually have to root my phone to start into TWRP. I read in one of the comments that that is necesarry. That leads to my next questions…
2a. Do I acually need to root my phone to start into TWRP (I just read that that is not necessary…)?
2b. If I root my phone, I suppose I have to use the option ‘ ADB only’. Is that correct?
2c. How do I know if TWRP is working?
2d. What happens next? Do I have to write command lines myself, or can I just reset the phone and install the image of Lineage?
And my last questions for now ;-)…
Do I need to download and install modem firmware?
I am still missing something?
Thnx a lot! That’s it for now
