The BLU Studio Energy is the same hardware as the Gionee M3. You can use the same ROMs. I am running a custom ROM for a M3 on my Blu Studio Energy, check out this thread here: http://forum.xda-developers.com/gene...-roms-t2977122
You can install a custom TWRP from the M3 which Ravi has developed and then custom ROMs and xposed framework. I am running the SAMUI rom and xposed framework is running perfectly. careful with it though, easy to softbrick the thing, but custom flashing the stock M3 rom using the original flash tool will break you out of any softbrick.
