SEUS updated my phone to CID53 and locked it to Vodafone network. This is first time i am facing this kind of problems. I love to use this phone.

Can any one please help me how can i reover my phone back to earlier version of CID ??(may be 52) or how to unlock CID 53 phone.

Your early response will be highly appriciated.

Cheers,
Kumar
You can't downgrade CID53 to CID52 and you can't unlock CID53 for free,only if pay
