I have a Sony Xperia SP C5302.
Its a Iranian Phone. And I am living in India. I recently upgraded to 12.1.A.1.201. But this Firmware is Iranian. So, how can I change it to Indian phone, without rooting or doing something else.
Can I directly Flash C5302_12.1.A.1.201_Generic.ftf ?
Yes, than which tool I have to use ?
Do it safe ?
