[Sony Xperia C] santo_20:
Hi, to start with my problem is that my device gone into bootloop after superuser install(i did not flased it with custom rom or anything). I've tried wiping user data and partition from android recovery but did not helped me. also tried with sony pc companion and wnshua also but both failed to flash my device. The device still in bootloop with sony logo

after searching on xda came across fastboot mode and bootloader unlock by which i can install my original kernel and then try to flash it with the default rom so i need help for how to access fastboot mode and how to unlock bootloader when the device is bricked.

tried by using flashtool but throws error
