[Anvesh Kotagiri]

Bought a lumia 1520 at a local shop turns out it is the starhub variant of singapore and it has bloatware and i am also not able to use the nokia mixradio app on it. I want to flash an indian based rom on this phone and hope for the best. so anyone who bought the phone in india kindly help me by giving the product code.
