error 561

I just upgraded my device to os6, but the 'updating applications' did not complete. Instead it displayed a message about 'invalid signature'. Pls how can i resolve this issue?

Re: error 561


To narrow down the guesswork, please provide the exact and complete error message, including all punctuation, codes, etc...from what you've posted, I suspect we have bits of the message -- your subject line is one bit, what you said in your post is another bit, but I don't think we have the accurate and complete message.

Also please identify the exact method you used to perform the update...there are many, and knowing the exact method you used will indicate a different resolution path.

Thanks and let us know!
