mfgtool2 damage two pico-imx7d SOM modules. Where it spoiled?

[neuberfran]

Hi,

I have this issue: My other imx7d pico android things start kit died, again 

I was following the steps of this link: iMX7D Pico won't boot 

I used the <LIST name = "eMMC-Brillo-uboot" script from ucl2.xml file

I left the script running beyond time. After Done appeared on the screen it was still running for about 8 minutes.

I think I found out what burned my devices. And the answer is in the link/iIMAGE below (despite being another SOM)

My questions is:  What component did it damage? How to make sure which component(s) burned? Why it spoiled?
