Xperia X: Can no longer launch apps after updating to SFOS 4.0.1.48

[teertinker]

Hello,
I suppose your problem is partially covered in the following thread:

Sailfish Core Apps do not work after Update to Sailfish 4.0.1.45 (sandboxing problem?)

REPRODUCIBILITY (% or how often): 100% BUILD ID = OS VERSION (Settings > About product): 4.0.1.45 HARDWARE (Jolla1, Tablet, XA2,…): XA2 Dual Sim DESCRIPTION: I want to open a core app (e.g. Mail, Phone, Contact, Notes, Documents, Mediaplayer…), at first startup it asked for permissions (e.g. to access contacts). I accepted. The app tries to load and can be seen on the app grid for two second and then closes. After this the app always closes. The phone is completely unusable at the moment. …

Some users report, the problem is caused by using a modified etc/hosts.

After some fiddle I had to reflash my phone to get my xa2 working properly.
