Extended_ROM Read Only - Can't Unlock

[PCronwright]

I'm trying to add a file and modify the config.txt file in the extended_rom folder however it says that it is read only.
When I run the unlock tool, it is giving me the following error. How can I get around this?

debug
ERROR:
FL_OICTL_BDTL_HW_PROTECTION - A device attached to the system is not functioning.

Also the device is a TelecomNZ - Harrier, and I am using the Unlocker from this page.

The tool does not seem to work on the harrier: I remember that there was another tool around alas I have no idea if that worked.

You need to look through the harrier threads about that, I dont rember which one.

Found this unlocker works.

Have posted it in the kitchen section of wiki.

Any instructions for this? (so that I can add them as well)

Yeah it was simple to use, copy the file to your Harrier and run it.

Also this is the post I got it from.

Some extra instructions if it doesn't work, but I didn't need to do this.
"If that doesn't unlock it, and gives a hardware io control
error, try using a binary editor on the file.
Look for ReIrRaH and replace it with eNiPlA
(Harrier and Alpine backward with alternating case). "

I have redone

Can you please check if it makes sense from a Harrier point of view, if you find anything then just use the edit at the bottom left of your screen.

Thanks

Done, I have changed the wording around for the install and excute a bit and removed the note about Harriers users not having an option to unlock.
