My phone has recently been rooted by a Colombian phone shop with magisk and kingo root in order to get around the homologisation issue there. Now some of my banking apps won’t work. If I do a fresh install of TWRP will my FP2 still be rooted?
Thanks for the reply. I noticed this today when going through the Lineage installation instructions, this is what I’m going to do before I return to the shop in a week or so. Does that come with SuperUser or something similar? Cheers.
(Expanding @Volker reply.) Before installing a LOS update, get a root file manager and remove all files in /etc/system/addon.d/exceptblacklist. If you have F-Droid Privileged Extension or Google Apps (GApps) installed, preserve those files accordingly named too.
The files there dictaminate what system modifications should be preserved between updates (they are called “OTA survival script”). That way nothing you don’t want survives and you have a clean system.
I just remembered (because I don’t need to use this normally) …
There is a setting in Developer options where, once the phone is rooted, you can set Root access to Disabled/ Apps only/ ADB only/ Apps and ADB.
This gives you a certain level of control, but the Disabled setting might not be enough for every App in question to run, e.g. some banking Apps might still complain depending on how strict or deep their checks of the system are.
Thank you, I saw that yes. In the end I followed Volkers advice to get my apps working again and then rooted the phone with addonsu-16.0-arm-signed.zip to complete the homologation (we don’t have a word for this) when I returned to the shop. It worked a treat, as did the addonsu-remove-16.0-arm-signed.zip so thanks for tip.
Three more days until I find out whether the process actually worked and I can continue to use my FP2 here!
