Hi! I've got a Dopod 577W. ROM ver: 2.0.11.0 Radio ver: 4.1.13.15_02.29.
I've recently installed a few freewares. Today my Camera and Video won't start.
msg: Access denied. The program cannot start becoz it is not digitally signed with a trusted certificate.
Then the phone will freeze. I've search tru' the forum but it really got me confused. Could anybody tell me how to disable this certificate request. Any help is very much appreciated.

I thought i just share this. I know maybe a lot of u already know the solution. Anyway the unlock works with my Dopod 577W.
Just visit this Wiki site n follow the step by step guide. If you don't want to edit the registry yourself, just use the HTCUnlock which do the registry editing for u.
