Phone shuts down when receiving or making call.

[Guest oldnewbie]

Upgraded my blade from gen1 to gen using tpt which added cyanogen mod 7 .

All seemed ok until i tried to make a call (or receive a call). The phone just shuts down and wont reboot until I remove and replace the battery.

Still shuts down if I try to call.

I have listed some details below in case an the hope someone can advise me.

Android 23.7

Baseband p729bb01

Kernal version 2.6.35.7 perf.

Mod vrsion cyanogen 7.1152011 nightly blade

Build no GWK74

Any help would be appreciated by this sad old geezer.
