So, you need to update DeBooxUpx.
Code:
C:\>adb pull /system/priv-app/OnyxOtaService/OnyxOtaService.apk
C:\>apktool d OnyxOtaService.apk -o OTA
C:\>grep "[^_ ](settings|upgrade|local)[^_ ]" OTA\res\values\strings.xml
Post the three lines of output or just follow what's in the Python file and add the lines yourself.
If you have a problem, just post strings.xml or even just the .apk
Lol, somebody beat you to it:
