Hi Everyone -
The short version of my story is that my dealer reflashed my truck to OS 12632483 and I want to flash it back to the original, OS 12606128. Doing a full flash seems like a scary proposition to me and I'd like to ask a few questions before I try it.
The .tun I file I have for OS 6128 was extracted using EFILive version 7.4.2 Build 657. I have now upgraded my EFILive to 7.5.5 Build 81 and my flashscan unit to bootblock 2.06.02 and firmware 2.06.06. I have opened the old .tun file with version 7.5.5 and saved it under a different name, per the sticky post by Ross. So it seems theoretically at least, I'm ready to do a full reflash. Is there anything else I need to worry about? Is the general procedure for a full flash the same as a parameter flash i.e., hook up the flashscan the same, turn the ignition on, start the tune tool? After the flash is done, will I have to do anything else, like an injector recalibration for example? Has anyone here done a full flash on an LBZ and encountered any difficulties?
I've had my EFILive for sometime but I haven't done much with it so I'm very much a newbie. Thanks for your help..
