Software Update on Flex 6600M

I have a Flex 6600M. I do not use a computer with it. That's why I have the 6600M. It's worked great since I purchased it until the Update 2.4.XX and 2.5.XX. I tried to update to the 2.4.XX and lost all mt profiles. I tried re-doing the profiles and it will not save them. Read all the release notes ans such. Turning the radio off, looses all the saved profiles. Tried doing a factory re-boot. The button turns steady white and never flashes. The radio come back on and the earliest profile is 2.3.XX. I choose it and same issue, nothing saves. I get bad audio reports!! On Friday, I called tech support and had to leave a message. Later got a email from Dawn and them tried to call back at 1:00PM central time and the message said they were already closed. Very frustrated!!!!
