This is my first post after getting a new Sony Xperia C (INDIA). Before this, i was a proud owner of a Motorola Atrix 2 !!!
I have seen many people searching (even i was one of them) for Xperia C root which is not yet available. I finally found a .exe in a chinese forum for Sony Xperia c39h and guess what i was able to root my phone in the 1st attempt.
Attaching the package, enable USB Debugging on phone, attach the phone to PC or laptop and then run the Sony Xperia C Root.exe. All the credits goes to its developer.
Enjoy Sony Xperia C users
