My S50 is still alive and kicking Got it 1/06/06. It's been hellish but at the same time one of the most used devices I own.
For some reason my son paused my S50 the other morning while I was in the shower. I noticed it went silent, but could tell the FM transmitter was still running. Expected to see it black when I went into the garage, but it was paused. The next day, around the same time. The show stops again. I grumble and head out to the garage, accusing my son of pausing it again in myu head, but this time it was black and off. Started it back up and had the new channels.
I haven't used MSS in ages, but I'll try it tonight. IIRC, there was a command under the Device settings in MSS to reset channels that sometimes would help with the logos...
You had new channels, but did you have the new backgrounds and voicetags as well?
