A friend has a Galaxy S4 on EE ,updated recently to 4.4.2. and having problems (major one being unable to text/call although phone shows full signal). Factory reset/cache wipe all done ..even works for a while after that then stops.
Now,i have googled and from what i can see she either needs to downgrade or upgrade the software .
I can do this (limited experience of rooting,so want to avoid custom firmware) IF i can find the software.
Anybody know where i can get the software ,either 4.4.4 or the previous version (guessing 4.4.0 ) and I think it has to be for EE .. ?
Or a workaround till the official update?
