1. A stable and battery optimized prerooted Kitkat or Jelly Bean Rom with integrated CWM (if cwm is not possible then twrp). Somebody on github has already worked on Kitkat for the Beam´s Novathor U8500 chipset see: [url removed, login to view] but if Kitkat is not possible then JB is fine
2. It has to have OTG (usb host mode) support
3. kernel should support overclocking
4. kernel should have swap support for virtual ram.
5. Has be able to play Full HD movies on movie players such as BS player, VLC or MX player and optionally on the preinstalled standard movie player. This was working on GB but not anymore on 4.1.2 JB.
6. Ideally it would be a CM rom (if possible).
For more info contact me pls. If some of these requirements are not possible then you can contact me as well and we can find a compromise. thanks
