I wrote a script and a program working together to solve the battery drain issue in Piranha Zen (clone of a117). I will share the roms to which I added the script/program in this thread.
The first rom is Lite-Kat:
Piranha Zen users can download the rom from my blog (android.durusu.net). If A117 users from India want this rom for their phone, I can port it. But no replies till now, still waiting :)
Hi to everyone,
I ported Miui v9 to Piranha Zen (clone of A117). If you want, I can also port it to A177. I am waiting your replies.
Another rom that I ported for Piranha Zen. You can use it with a117 also.
First install the rom : https://yadi.sk/d/R0YTKGbnsWfjq
