I'm surprised that there are modern Tegra devices shipping with identical SBK across their production line.
I would have thought they'd do some mixing based on serial number or chip id as a baseline.
Or at least that's what the hash of their SBK implies.
I do enjoy seeing the boot chain on Tegra get broken yet again though.
The 80% chance that someone develops a bootloader exploit is my favorite part of owning COTS Nvidia hardware. Doubly-so on locked-down platforms like the Nintendo Switch that really do benefit from having a homebrew store.
