Sorry i dont know? how do i find it?
No problem. Connect the phone to XS++, and post the log.
How to do:
1. download the XS++: XS++ v3.1(Darwin)
2. install the USB Flash Driver: USB Flash Driver Installation - Guide
3. start XS++ and click on Connect button and connect the phone.

How to connect the phone to flashing tools:
When XS++ says to press the C key and connect the cable you need to:
1. Turn off the phone(if it was turned on)
2. Remove the battery, wait a few seconds(2-3 seconds is enough) and put it back, but DO NOT turn the phone on
3. Press and hold the C key on phone and connect the DCU-60 cable(data cable, what comes with phone).
4. When you see some progress on XS++ status window(on left side) release the C key.
