[Android General] sandrap:
not sure if it matters - just got "failed to install due to an unknown reason" again when trying to install a new app. Of course followed by "optimizing app..." after the necessary reboot :(

I deleted

-everything from "shly" (including the launcher! so be sure to to handle that; e.g. install another one before removing that)

-everything related to FWUpdate/sysupdate/adups

-"Shell"

-lovelyfonts

-scam.tgr, scam_sony.tgr

-theme***

That's just what i can remember at the moment. can compile a detailed list tomorrow. (difference from factory image to my current setup)

As I said: It definitely did not help with the problem of installing apps->reboot->optimize apps.

EDIT:

removed from /system/app

not working: fingerprint reader

IIRC i did not remove FP reader related stuff, when the systemUI crash bootloops happened - still there seemed to be errors related to that (see attached logcat!!!)

Also I have been using the phone for a whole week after I accidentally removed the fingerprint framework, just to re flash my phone with the hope to get it working too -> then bootloops again
