Bricked P59 Help

[Jose_LSX]

Hello guys, my p59 from a silverado 2003 5.3 DBW is bricked
I tried to ground the weld point but it doesn't work, the second time it happens to me, the first time it worked but not this time.

I got a computer from a 2003 suburban with the same blue/green connector at my local store. What is the procedure to transfer everything from my bricked ecm to the new ecm? whole write, segment swap? I have the last file of my bricked ecm and what recommendations do you have to deal with voltage drops. Thanks to all for your help

If you have the stock tune from your OG PCM then id do a write entire on the new one and just start the tune over. Or transfer whichever tune you want i guess, just do a write entire. If you dont have a copy of your old one then get one that has the same OS as your original and use that tune.

yes i have the last tune file from my bricked pcm, can work?

should, just do a write entire. why did your other one brick? if it bricked from improper TAC module adjustment then Id use a factory tune and recalibrate everything correctly.
