N14 ecm flash problems

[windowrattler]

I could be off on my terminology a little bit between bricked/rom boot it's been a little while.

My very first time flashing any cummins hd ecm was a n14 that we did an out of frame and built the engine as a higher hp cpl. The flash failed and I was stuck with an ecm that had no comm and no start. 8-10 hours later and doing a lot of digging the procedure I listed above did flash it. I haven't done a ton of the older ecms but every time with the older n14s and even one m11 I've had the flash fail and this weird battery disconnect key dance thingy has worked. It's free to try.
