Modify RUU?

[fzzyrn]

Is it possible to modify the file that the RUU writes to the device. I've noticed that when the RUU is installing, it copies a "RUU_signed.nbh" file to somewhere. Im guessing that it then extracts/writes RUU_signed.nbh to the device.

SO would it be possible to replace the RUU_signed.nbh with one that you get frm some custom ROM?

bump. Oh and by the way, if it helps, I'm have a Wing/Atlas/Herald.
I think the idea here is to figure out where the RUU_Signed.nbh file is stored before being written to the device.

Any help?

use winrar with the exe upgrade file... :)

oh wow. never thought of that. gonna try. hopefully this opens up some sorta new frontier in rom flashing. probably not, but the possibility to be able to flash via modded ruu sounds cool. feasability?

sorry for the double post, but i've now managed to disassemble the RUU via 7-zip and have inserted a custom rom in place of the normal RUU_signed.nbh file. Heres the funny part. How how do a i reassemble it. Maybe it's possible to just RUU without reassembling, but it makes everything easier to manage
