Glad to hear you got it working. You are one of the few people who have asked for help and actually described the error and what you have already tried, and you didn't quit and actually fixed the issue and posted the result.

Most people on this forum or more than glad to help but it's frustrating when people complain about a problem they are having and state "This tablet sucks it can't do anything and Nokia should reimburse me for the time and money I spent on this", without giving any explanation of what the problem is and what they did right before the problem started. Most don't even think about searching and trying to find out for themselves what the problem is.

Again good job and enjoy your working 770.
