We have read and flashed this vehicle before and upon doing the V7.5 and V8 updates when we were flashed in a new file it erased the PCM and left it dead. I have contacted support and they replied with send a new read file, not a previously saved one which is impossible due to the PCM being blank. Any help would be greatly appreciated. Currently we are downloading previous version of 7.5 and 8 to see if this works. Thank You in advance.
