Well, I have never said phone was not booting. It is booting just fine.
Yesterday I have boot to recovery and I have pressed almost every possible wipe/format option possible in there. Then I have sideloaded
CM11 Gapps and Radio. Seams to be fine now. I don't know why but it almost looks like my phone was somehow different from other g2's Folder structure was different. For example no /sdcard/android , it was in /storage/sdcard0/android
Although there are still few things bothering me. Memory. Total storage reported is 10.62GB. Phone is 16GB version, from which I would expect about 15GB of usable memory. So where is missing 4GB? Do you people with custom ROMs have the same? anyway to get it back?
