Error when I try to dump OTP.bin with de_fuse

[benefits]

I have been trying to fix a Hynix Wii U. When I try to dump the OTP via the "dump OTP with PRSHhax" option in minute_minute I am given the error:

Warning: SEEPROM slot0 boot1 version v46747 does not match NAND version v8354!
Warning: SEEPROM slot1 boot1 version v36075 does not match NAND version v8354!

If this is the first time you're dumping otp.bin, ignore this message.
However, if you reflashed boot1, you might have to guess which boot1
version was originally on NAND and will match the SEEPROM version.

I Used NANDBinCheck on SLC.raw and this was the result:

NAND Type: SLC (WiiU)
checking boot1...
Boot1 hash: "ce762b004200f2400f5818f07bb107992d61050d"
Boot1 OK!

I've been trying many different methods to repair the issue. I'd greatly appreciate advice and suggestions.

Update: I got a minimally working otp.bin using otp-builder.py. I was able to open ios.img isfshax. but unfortunatley the isfshax installer states:

Console Type: Retail
boot1 version: Unsupported (8354)
isfshax: Cannot be installed

Are there any know solutions to this issue regarding the boot1 version?
