I tried to change the default ROM to MIUI developer ROM (4.8.1). I put my phone in fastboot mode, and tried to choose the ROM file from MIFlash application while connected to PC. It was throwing file not found exceptions. so I wanted to terminate the process, so I pulled battery out. Later I put battery and tried to turn on phone. It seems to be dead. Cannot see anything, cannot restart the phone. I put charging for whole night. still cannot restart the phone. I cannot even see the charging light while charging. The notification light blinks now & then in red color. Could anyone suggest what I can do?
