RevG with boot loop

[ElDominio]

I have a revGboot looping if powered from 12V, but works fine if first powered by 5v.

I have tride Full DFU Erase and reloading firmware, but not improvement

[rusefillc]

@ElDominio I see a statement. I approve this statement.

What is the question? Are you looking to check if all 2chan rev G do the same? Something else?

[ElDominio]

Yes, I would like if others do the same, and if this is a software or hardware problem

Two RevFs I have tested in the same car boot properly, but VR does not work on them for reasons unknown

[ElDominio]

I found an old revG with 2023 firmware, and it was booting up fine. Updated to latest and revG does not boot loops and RARELY finishes booting. RevF boots fine

[rusefillc]

@ElDominio I have rev G and I am able to reproduce the issue. I have to confess that I was totally NOT expecting this to be a firmware issue.

@ElDominio I need help. Can you please run a binary search between official releases and/or daily builds and attempt to isolate the issue?

[ElDominio]

I've already downgraded to Dec2023 and still boot loop :(
