I am new to EFI Live and downloaded it the other day. After downloading and upgrading to the newest version, including bootblock and firmware, I have errors including, Can't get semaphore for control of EFILive_Hapi, Request was ignored - i.e. reply cmd<>send cmd, and No data received. I have uninstalled 4 times (not kiddin) and reinstalled and retried but the same errors keep happening. Another problem is my usb connection, the frames, being transmitted and received have only matched up twice. And even after they did, I got on scan and tune and the error, (No Device Detected) appears. Plz help. I am trying to get efi live installed on my 2011 2500hd chevrolet 6.0. Help would be GREATLY appreciated.
