Need some help as a nood for my HTC One S

Hey all this will seems to be quite an odd thread to all. but its been long i have been using generic HTC one S and i know this site very well since i bought my phone 3 years ago!

Very well, I need to know some basic stuff so i can get perfect mod and upgraded without making it available for my younger brother to play with it by throwing it on wall. ;)

So a good help will be really appreciated.

Only couple of questions:

1. Best ROM that support Indian HTC one S models.
2. Best and 100% working method to get this done successfully.
3. Any way i can backup the generic ROM and framework and get things moving ?


please don't get angry on me, just help me to get my phone renovated.

Thanks XDA :)
