Newbie: help needed in upgrading CM on resurrection remix n7100

entlemen, I am quite new to custom OS on Android but have fair share of knowledge related to IOS.

I installed CM 6 on my android and installed resurrection remix OS. Now I am not able to update to CM 12.

What I did:
1) downloaded latest nightly build from Cyanogenmod.org
2) saved in external memory
3) installed it via recovery mode.

The result was error and some status 7 message came. Thanks to the backup, my phone is good and working.

What I want to do:
1) upgrade to CM 12 or best stable ROM
2) install ios7 theme via xpose repo

Any help is really appreciated.


Thank you

N7100 keeps lagging even after a ROM clean install

I was on Resurrection but my phone started lagging pretty bad, it was really annoying so I decided to try another ROM. About 2 weeks ago I switched to BlissPop (clean install, system, data, cache, all wiped), everything was perfect until this week, my phone started lagging again, it does it on specific moments, not all the time, but still pretty annoying. I just have 96 apps which I think it's not a lot, most of them are from the GAPPS package and a couple of apps I use. How can I detect the root cause of this lag?
