It's a 2017 unpatched version that I bought on ebay as "no power". It definitely does have power, as I can boot into RCM, but I'm not too sure on how to fix it.
Basically, it will only boot to the Nintendo logo normally, but if you remove the eMMC module, you can put it into RCM mode, then insert the eMMC again afterwards to have access to it, so it doesn't seem to be a hardware issue. I'm guessing whoever had it before has bricked it in some way.
I tried to follow a rebuild NAND from scratch without the prodinfo and such, but even with a new eMMC from another switch that has been fully rebuilt, as far as I can tell, it won't boot.
Has anyone encountered this before? Is it normal that a corrupted eMMC would stop even RCM from being available?
