trying to pull my stock file out so i can flash in a EFI tune, everytime i try i get an error code saying the bootloader failed, retuned to normaln operation

it has an aftermarket deck, so i pulled the radio amp fuse (if i pull both the radion and the radion amp it always says "ecm connection lost" part way through"

left the batteries unhooked over night

tried the driver door open trick didint work

running out of ideas on this, need some help!
anyone else have an LLY that was this tricky? i NEED more tips on how to get her done. thanks all

ok finally got it!, ended up taking the radion fuses out (both of them)
took the radio head unit completly out
unhooker the batteries for 30min
hooked them back up, put the battery charger on it and wa-La! she worked. only took about 6 hours of messing around with everthing to get it all figured out.

Next time, try "alt keys" and "low speed"

Pass thru only works if only the blue ECM connector is plugged in and rest are out. Fails about 3/4 way through. BBF doesn't work at all.

Funny, I am not having any issues at all, only thing that really screws you over is an aftermarket alarm that interfaces with the CAN Bus

Just downloaded the June 1st update. Hopefully that cures the issue.
