Can anyone help me how to upgrade my xperia m firmware from 15.1.C.1.17 to 15.1.C.2.8 without Sony PC Companion?
I've tried so many times using Sony PC Companion, but it didn't work.
Yes, I'm following all of the instruction. Like :
1. Unplugging the USB from computer
2. Turning off handheld and wait for 5 seconds
3. Plugging the USB to computer
4. Plugging USB to handheld while pressing volume down button.
Yet, it didn't work.
Anyone have solution? :angel:
