stable 6 is just amazing for me:
dirty flash (i.e. dalvik and cache wipe) + pico opengapps + supersu - in one go
Dirty flash also worked for me with no issues.

I have the same problem with download unsuccessful. What I did was make a back up of internal SD and then wipe internal SD in TWRP. I then reflashed my current ROM and gapps. Copy files back to internal SD and now I'm able to download from browser...
its based on ics, I thought it was based on jelly bean
