I have the tune saved elsewhere (manytimes over). I was just testing everything I could before doing the full flash. Does anyone know how confident I can be if I successfully TEST a full flash?

Bingo! Nervous for the Big Flash I guess. It flashed fine today thanks for the help. Figgen'barassed

I downloaded the current builds today onto a new laptop with hopes of installing a new tune. I updated both V7.5.7 and V8.2.1 successfully and then updated the firmware on my V2 successfully. ...

I don't know. The stock tune would write fine but the truck would crank and not start. VATS relink was done 2 or 3 times, batteries unhooked, computer rebooted, write the tune again, etc and no...

It runs and STRONG! I downloaded the DSP5 tune which started this whole deal and it started :woott:

No idea why the stock tune wouldn't run it as the DSP5 is built off that but whatever. It...

I think the 3rd ECM is bad too. Did the VAT Relink twice and did Key-On 15 min off 30 seconds 4 times too. No codes, crank but no start. Looking for a fourth ECM but hopefully we can unlock the...

I tried...

Do I need to be concerned with my licences when updating the Flashscan?

Am I updating Firmware and Bootlocker? 2 separate updates?

Thanks

I tried using V8 and it wouldn't communicate with the Flashscan so I went back to V7.5 (which I did update) (I'm using a different laptop for each version)

I suspect the Flashscan firmware did...

Long story short;

I went to do a full reflash with a new DSP5 tune and it got into a "Retrying Previous Block" loop. I let it go about a dozen times then hit stop. Then no ECM response so keyed...
