Bootloader rejected and no response from truck

[abkimble]

Hello all

During a tune write, my power cord to my laptop was removed by a pilgrim. Now I get bootloader rejected with a possible locked ecm. Any suggestions?

Thanks

I had a battery crap out on me during a flash , did as the other guy said , disconnected the battery and the V1 or V2 and after reconnecting the battery and V1 or V2 did full re-flash with stock .tun .
From what I remember reading was it depended when the interruption happened , what segment of the flash it was in . I think the first 4 seconds is the worst or when the red light is lit on the stop light indicator , yellow or green can be recovered from .

Put that in as the key and see if that works. If not, you can send me the pcm and i will take a look at it.

Hello and thanks for the suggestion.

I tried this key with no luck.

I'll look you up for possible mail in repair.

Thanks again.
