Unable to dump OTP.bin with de_fuse

So maybe the SEEPROM is just bad. In that case we have no way to dump the otp. Your only way to use the console would be with defuse and a donated otp. Also we would need to add SEEPROM redirection to stroopwafel. I had planned implementing that some time but there wasn't much demand. Now we would have a usecase.

Just to be clear this is the content of the SEEPROM after a reboot

If you need a usecase I could support :-) Thanks!
So the PIco should remain inside the WiiU otherwise the Wiiu will not boot?

oh it wont restore without a otp. at least the seeprom key is the same between all retail systems

you were right in minute there is a check

printf("Verifying seeprom.bin...\n");
if (!crypto_decrypt_verify_seeprom_ptr(&crypt_verify, &to_write)) {
printf("\nSEEPROM failed to verify!\n");
printf("(A valid otp.bin is required)\n");
goto ret;
}

so I tried using an OTP from a different WiiU but doesn't work

Restoring SEEPROM from `sdmc:/seeprom.bin`...
Verifying seeprom.bin...
Everything verified!

Last chance: Are you sure you want to write SEEPROM?
If you write an invalid SEEPROM and then fail to backup
otp.bin, you will NOT be able to recover your Wii U!

A missing otp.bin can ONLY be recovered with a valid
seeprom.bin from the SAME Wii U, and a missing seeprom.bin
can ONLY be partially recovered (enough to boot) with a
valid otp.bin from the SAME Wii U!

If you lose BOTH otp.bin and seeprom.bin, you will be FORCED to
use a donor copy from another Wii U.
This *may* mean forfeiting the ability to play online!
This WILL mean saves stored on NAND or USBs will be unrecoverable!
This WILL mean your disk drive will no longer be usable!

This is like, the one limitation of de_Fuse lol.
You probably don't want to be here unless you're a developer
and know what you're doing.

Write sdmc:/seeprom.bin to SEEPROM?
Please enter the Konami code to continue.
[POWER/Q] Abort

WARNING: SEEPROM boot1 version v46434 does not match NAND version v8377!
Continue writing sdmc:/seeprom.bin to SEEPROM?
[POWER/Q] No | [EJECT/P] Yes...
SEEPROM write failed!
Readback did not match!
SEEPROM failed to verify!
(Check your otp.bin?)

can you get pics of the entire board? super weird that a WUP-50 is having these weird issues
