udpih can unbrick a wii u bricked by cbhc, i tried on my bricked wii u a few months ago and it worked! search udpih on google for more information.

As far as I knew, that didn't exist back in 2017, also my Wii U is LONG gone by this point except for the GamePad.

yeah, unfortunately udpih was released on 2022 and not in 2017, nand backup could unbrick it, but sad that you lost your wii u

what does CBHC do? iv'e heard of it but most said its dangerous. sorry this happened to you.
