T42G Will not update firmware

[itdweeb99]

There is a brand new version of firmware on yealinks site for the T42G. I downloaded it and applied it to one of our phone and I am actually seeing what is happening. I think it is applying the new firmware and then rolling back to the old version because for just a few seconds, I saw that the phone was reporting the new firmware version in our 3cx console. However, 30 seconds later, I notice that the phone is offline. Once the phone comes back online, I see it showing the old firmware version in the 3cx console and on the phone interface.
