I flashed via CWM and it softbricked my phone. Probably because it was KK5.
I reflasehd the entire ROM again. Factory reset, Format cache, dalvik cache, system, twice + kernel cleaning script. Problem reappeared again.
It seems when it goes or comes out of deep sleep it loses the wlan connection.
Automatic reconnect after coming out of airplane still doesn't work.
And on a side note.
Now even with the SAMSUNG original 2.000 mWh battery I get above-average battery drain. Tried several kernels, Red pill, Neak Speedmod. No significant change. Deinstalled facebook and ebay app. Deactived GTalk and network location . No change. Under Speedmod I get crazy suspend and events/0 wakelocks and the tvout two resume process is harassing my phone way more than I was used to.
I know, I complain a lot but never had to deal with so much issues at once. Is someone else experiencing the many problems.
