Everything was fine, but trying to find some info on the possible culprit for the battery standby drain, I found somewhere that it could be a problem with the Russian region UAMF7 rom. So, I downloaded, and installed the Indian DDUAMJ2 rom, rooting using arco68's files from http://forum.xda-developers.com/show....php?t=2494435, but didn't have wifi, so I then flashed MJNazari's kernel from http://forum.xda-developers.com/show....php?t=2431953.
Now everything's fine, wifi works, still don't know about the battery drain, but information in the "About device" worries me.
The build number is fine, JDQ39.I9192DDUAMJ2, but the Baseband version is still showing I9192XXUAMF7 !?
Is this normal, and have I messed something up somewhere?
