Hacking Discussion bios chip firmware reverse

[ii_lum]

the Nintendo switch likely has a bios chip, probably containing kilobytes of data, making it possible to re-engineer the code, you could sniff the chip with an inexpensive programmer
the bios likely has the way to repair and put the switch os on it, similar to the method of putting homebrew on the system, we get the bios we find out how the bios is accessed and how the os is put on the switch, we recreate the process to run cfw, this is just an idea, but I've bought a switch motherboard and i am planning on sniffing most of the chips on the motherboard, and dumping them.
onto multiple platforms. sinc

Erm...good luck then

The irom is integrated in the SoC and was dumped years ago.
We also know exactly how all the OS partitions are formatted (I've done OS installs completely by hand a couple times myself, actually (and I don't mean that Choi shit or whatever))

What we don't have is the RSA-2048 signing key that we'd need to make the bootrom think our code is valid.
And no, we can't change the RSA keyset, the public key is burned into the hardware and write-locked.

Do you even know what you're talking about?
