If the flash failed during write entire the ecm is likely not recoverable.
It doesn't have to be perfect, it just needs to be done in two weeks...
A wise man once said "google it"
Try Pulling the Stereo fuse and write again... It worked for me on my 06 Silverado...
DO NOT disconnect the battery. That will brick it in it's current state. Hook a jump box up to make sure voltage is good and perform another write entire.
