You can't make a NBH upgrade out of a extracted ROM dump. The NBH file is signed with private HTC key, and bootloader checks signature before flashing it. There is no way to circumvent this at the moment.

Is there a way round the signing of the nbh? I would like to play with a cooked rom on my phone...

I'm assuming a CID unlock won't fix this, eh? Bastards...

The ROMs are CID 00000000 anyway....

But they always error when you try and use a *.nbh which has been cooked (same process as hermes) as its not signed. Need a custom SPL which allows unsigned code to run...

Damn. I was looking forward to making a few adjustments to the Cingular ROM. Oh well, maybe in the future...

I've retired my trusty Wizard and moved to a 750, and I'm on the fence about digging into the 750 or waiting for the mythical 320x320 successor. It's killing me that I can't get some custom ROMs going though, so....

From what I gather doing light forum reading, we need a mod'd BL that will load an unsigned image? Is this chk done at flash time only or at every boot? Has any work been done on the Hermes side of the house that can be leveraged? I'll duck into their forum and read up.

I swear the the 750 is so close to my ideal device...it just needs a slightly larger display, VGA, and a radio that supports HSDPA 3.6. =)

damn haven't seen you post in a long time. your wizard roms made the device actually useful lol

custom treo roms would be great. good luck in the search for info. I haven't been able to find anything all that useful, but hopefully your search goes better.
