[HTC One X] nitrous²:
I have the bad feeling that we got our wires crossed :D

So, what I did with the sdcard and the OTG-Y-Cable on "RELOCKED" and "UNLOCKED" bootloader;

a) Put DIAG onto the root of sdcard> plugged it into the female end of OTG-Y-Cable> plugged it into the one x> plugged the male end to psu> rebooted into bootloader and got the error message.

b) Put DIAG onto the root of sdcard> plugged it into the female end of OTG-Y-Cable> plugged it into the one x> plugged the male end to psu> rebooted into "red fastboot" with adb reboot oem-34 and got the error message.

c) Made a goldcard out of the sdcard> Put DIAG onto the root of sdcard> plugged it into the female end of OTG-Y-Cable> plugged it into the one x> plugged the male end to psu> rebooted into bootloader and got the error message.

d) Made a goldcard out of the sdcard> Put DIAG onto the root of sdcard> plugged it into the female end of OTG-Y-Cable> plugged it into the one x> plugged the male end to psu> rebooted into "red fastboot" with adb reboot oem-34 and got the error message.

-----------------WITH USB-STICK-----------------

e) Put DIAG onto the root of usb stick> plugged it into the female end of OTG-Y-Cable> plugged it into the one x> plugged the male end to psu> rebooted into bootloader and got the error message.

f) Put DIAG onto the root of usb stick> plugged it into the female end of OTG-Y-Cable> plugged it into the one x> plugged the male end to psu> rebooted into "red fastboot" with adb reboot oem-34 and got the error message.

g) Made a goldcard out of the usb stick> Put DIAG onto the root of usb stick> plugged it into the female end of OTG-Y-Cable> plugged it into the one x> plugged the male end to psu> rebooted into bootloader and got the error message.

h) Made a goldcard out of the usb stick> Put DIAG onto the root of usb stick> plugged it into the female end of OTG-Y-Cable> plugged it into the one x> plugged the male end to psu> rebooted into "red fastboot" with adb reboot oem-34 and got the error message.

i) Made a bootable usb-stick out of the usb stick> Put DIAG onto the root of usb stick> plugged it into the female end of OTG-Y-Cable> plugged it into the one x> plugged the male end to psu> rebooted into bootloader and got the error message.

j) Made a bootable usb-stick out of the usb stick> Put DIAG onto the root of usb stick> plugged it into the female end of OTG-Y-Cable> plugged it into the one x> plugged the male end to psu> rebooted into "red fastboot" with adb reboot oem-34 and got the error message.

It was a hell of a work, but at least no one has to do it as it's not working with the goldcard method. It won't work because goldcards are meant to work on QUALCOMM devices. Why are we still talking about them? Even on the S-OFF development thread it has been proven as non working...

This would be useful if our bootloaders weren't unlockable, but thank god we have HTCdev (*sarcasm*). The ASUS had to get ONLY and unlocked bootloader, they don't have S-ON/OFF problem and thats what the blob/nvflash thingy is all about. It just unlocks the bootloader of th TF series. It won't help us achieving S-OFF.
