Power doesnt stay on or phone is jammed

If this kind of fault has come after flash programming, there are most probably open pins in IC's.

Normally the power will be switched off by CCONT (N102) after 30 seconds, ifthe watchdog of the CCONT can not be served by SW.

The watchdog updating can be seen by oscilloscope atJlOO (DataSelX from CCONT). In normal case there is a short pulse from "1" -> "0" every 8 seconds.

The "power off" function of CCONT can be prevented by connecting a short circuit wire from J102 to ground.
