GAI4000 thanks for the answer. Well now I have encountered another weird issue 'Unfortunately, the process com.google.process.gapps has stopped' I'm using the gapps on the first page and the rom is 10.2. Something I'm missing here?
To further extend my question, I was using 10.1 and upgraded to 10.2 now keyboard and system keep on crashing and the phone is pretty much unusable. So I would like to do a clean wipe and install the rom + gapps.
I have cleared the the dalvik cached and upgraded from 10.1 to 10.2, everything seems quite nice/polished so far. But I'm not longer unable to connect to the internet via google play store, overall connectivity is established(browsing, etc). I have had a look at a few solutions to this problem but neither seem to work for me, the xda guys suggest modifying the hosts file in the /etc/ but I'm unable to do so due to permission issues even though I have granted full access to 'total commander'. Do I maybe need a specific version of google play store? Any help would be highly appreciated.
