RGH Retail Updates fail -> Console Brick's

[Cronix]

Hi Community,
i really hope someone here is skilled enough to solve my issues.
at the current state my XboX 360 seems to not like M$ Retail updates anymore,
I installed a cr3 lite, a demon and a sonos to my XboX 360 Slim Limited MW3 box (corona v3) and all worked perfectly before the last 2 updates M$ pushed out,
currently if i try to install a dash update to the retail nand via the official M$ way to do that, my console freezes (yes it really freezes trust me, controller LED still lighting even after i pull the battery of said controller or the usb cable if it is tried with a cable controller) the screen turns black, signal via hdmi is lost and after a reboot it is bricked,
i can revive it using a nand backup and jungle flasher with my DemoN from my Windows XP Laptop to restore my retail nand to the last working state but 2.0.16537.0 + 2.0.16547.0 won't install,
i tried to get the system updated using internet update, burned the updates to dvd and using an USB stick, i even hooked it to an old CRT TV via analog cabling to check wether the hdmi connection is faulty without success.
Anyone can help me solve this mistery?
i want to get the box to update to the latest retail dash again, this worked well before and i haven't changed anything on the system inbetween.

i can revive it using a nand backup and jungle flasher with my x360 usb from my Windows XP Laptop to restore my retail nand to the last working state

This statement makes me think that you dont have enought knowledge about what you are doing and how you should do it.

im sorry i messed up my post :O
scratch the x360 usb part and replace it with the usb port of the demon ... *blushes*
Martin: i'm sorry but i have no idea about what kind of "useful" pics i could provide as the box just hangs after an attempted retail update.
I "could" provide pics of my soldering but those parts work as expected (glitch nand still boots and works fine and if i flash stock nand back to the version before the update it works fine aswell) so i dont really see a need for those pictures.
please correct me if im wrong / missed something

If you can't perform a retail update on your 360 NAND then something definitely isn't right with your install.
