It's working now???? I pushed "test" instead of start on the reflash screen and it communicated so I tried a reflash and it worked??? Weird LLY issue???

Alt keys? High and low speed? Close and reopen tune?

Sometimes all it takes is for you to pull the plug from the OBDII port and pull the USB from the PC to power down the flashscan.

LLY's do suck.........the worst to flash in the trucks of all the models

Really? I've always had more problems with the early LB7 OSs. Huh

My LLY has been great

I have this issue with some 03-04 LB7's too? I finally got it to accept the flash last night, I went to do a full reflash and hit the test button instead and it communicated I waited for it to complete the test mode and hit start and it took it. Good thing too I was stopped in a parking lot not at the shop Would have been a tow for sure, only thing I could think of was the issues Ben Tyler had with an LLY ECM that wouldn't take a flash!!!
