I have searched the forums and haven't found a thing that works for my phone. I rooted and backed up my current version this morning (4.2.2 stock) using CWM. I then proceded to install Wanamlite 1.5 for the S4 GT-I19505, which installed but had serious issues with sound, everything would crash when the volume controls were pressed or headphones inserted. I therefore switched ROM to Android revolution HD 1.0. I installed what I thought was the relevant wifi fix, but no joy.
At this point, I restored to stock 4.2.2 hoping it would solve the issue, but it hasn't, my cwm backup also has the issue after attempting to restore.
Anyone got any suggestions of how I can fix this? I thought the stock restore would have done this, but obviously not.
I am running android 4.2.2 on a stock rom (XXUAMDD_I9505EVRAMDA_EVR).
GT - I9505
If you need to know anything else, let me know. Thanks.
