Thanks for the reply. I was on 195 MB system and now used tpt helper to go to 220MB.
Wifi is not working for me either, I also had some problems with the home button not working, but that was probably because I was on 195 MB with a trimmed version of your ROM and gapps (Removed tts, bootanimation, lockclock) but even then 195 was filled 100%.
Eagerly waiting for your new build!
You have a bad download, download via GooManager, it will check the md5sum for you. I had no problems installing.
BTW as the CM update script formats system, you don't have to do much when updating. Just flash the rom and gapps.
