A repair notebook that outgrew the paper.

I am M. Ellison. I logged Xbox 360 motherboard jobs from 2019 through the RGH3 years and into the Bad Update era. Corona Notes is the public version of that notebook: board IDs, 4GB eMMC surprises, PicoFlasher vs xFlasher, and the first-boot work people skip because the glitch LED looked confident.

This is not a storefront and I do not take mail-in RGH. If an article cites a KV source, J-Runner with Extras, or a software guide, it is because that is what sat on the bench PC — not because this domain sells iron or files.

Audience is anyone still in the 360 scene in 2026: RGH3 Trinity owners, Winchester E users on dashboard 17559, Jasper collectors, and people who only want Aurora and a 2TB FATX drive. You do not need to be mid-unban to need a correct dump.
