Best Rom for NL 920

[mihnoi]

What rom do you guys think is problem free or almost problem free ? And can someone give me a RM-821 product code for that rom ?
I can't seem to find a rom that doesn't have heating and bad battery problems and i flashed my phone 10 times in the course of the last 2 months and all of them had those problems.
The developer rom was particularly good but still had heating issues and the battery was kind of better.

Windows Phone is not like Android. There aren't any home-brewed custom Roms. The different Roms you have been flashing are most likely language and carrier variants with identical feature sets. The battery and heat issues you described are subjective. When you do something processor intensive, your device will heat up. Any handset will do this. There are a number of threads to do with how to get the most out of your battery on a Windows Phone.
