Is this stock or custom rom?
With or without bloatware?

I thought this rom is only for L7 p700. How about P705 is it work?

Yes ,everything works even better than ICS, smoother also , stock camera app didn’t work for me but then I installed Camera MX from Play Store and now works perfectly, and mine is P705, it has the NFC buttons but it doesn’t function as it doesn’t have the NFC antenna as the P700.
