I want you to help me.

I use tsu9300 and want to update firmware.

I operate updater with a PC,and tsu9300 does not do reboot and makes lockup with philips logo screen.
Using the key combination that forced update mode contains.I tried a mode plunge,but do lockup with philips logo screen.

By reset,normal movement is possible.
The xcf downloading from a PC is possible normally,too.

What will be wrong?
Tsu9300 is Dameged?
