You will have to repair the track - on the C65, you don't cut this track, just short it to ground during boot.

always totaly dead! please help!

Have you repaired the track? If so, then you either cut too far into the PCB and damaged one of the internal traces, or you have damaged the CPU.

Get a powerful magnifing glass, and check around where you made the cut.

I also cuted tracks and try to joint it again but I think some inner track or something else is painful to me. Can anybody give the solution ? A working phone is dead by testpoints and want solution urgent.

First time i was trying to make test point i solder too big cable (heavy) to the test poing, and when i released it from my hand - it fall down and cut the test point. I repaired it with more tin. And it works. I don't know your situations. I wanna help, if you can send me Pics of your PCB's
