truck wont start, controller in an unknown state.

i was falshing my lb7, and the ethernet cord came unplugged from flashscan tool . started over, seemed to flash fine, but wouldnt start. Having read the warning that pops up, i tried flashing with 7.5, but itr says controller in an unknown state. when i try flashing w/8 it says security access denied. What to do?

Your ECM is likely a very expensive paperweight now.

Very expensive since it is a brand new ECM.

Have you tried disconnecting the batteries to fully power down the ecm?

I pulled the ECM fuse, is that the same as? It didnt work, so I put my old ECMback in so i can drive it...the old ECM has forgotten its unlock code, and I cant pull a read or a flash off of it, but it works

Send the dead one to us. We can restore it if it is still viable.

Use the V8 flash option and check the two boxes:
"Try Alt Keys" and "Assume lock is faulty"
