xbox slim corona wont boot on demon nand

[karl.c]

Hi guys

I have a xbox 360 slim corona i was runing it as just an rgh console
then decided to dual nand it. Everything was working fine its been
about 8 mouths since i dual nand it but when it come to updating
nand to latest 16547 dash its gone crazy.

everytime i flash the demon nand with either Freeboot/Stock
sometimes it power's up but when i turn it off it's like it losses
the flash because it wont turn back on.(onboard is still working fine)

Xbox will boot fine from onboard nand
Xbox Will Not boot demon nand with Freeboot/Stock
Iv'e checked all wire's/ribbon's
From CR to Motherboard
From Demon to Motherboard
From Demon to CR

Everything is fine i don't understand whats going on with it
it was working fine before i started i wish i never tried to
update it now.. Hope someone here can help me out on this
would be most appreciated thanks

(I will post pics if you need to see some)

Post pictures of install. Also try filling out the RGH Template, sound like a bad solder joint, worst part is that it could be on the carona demon adapter, that is under the demon, so even with pictures, you may need to remove the demon to test. The best test would be to do a continuity test from the demon wire points directly to the onboard nand chip itself.

hi thanks for the reply if it was down to the install it wouldn't work for 8 mouths in the first place that's what i don't understand
iv'e got it booting couple of times but pops a error 71 message but i will post pics in about 20min taking some now

here's some pics sorry about the quality of the pics

soldering could be touched up. Some of these points look cold, or could use more solder. I would apply some flux, and go over all the demon points again. Also I would see about removing some of those solder spikes, to prevent shorting.

Ok thanks for the reply i will go over them today and get back to you with the outcome

This error is related to a failed dashboard update, can also be NAND related if you have an Infectus chip....
It can also often be caused by a cold joint under the Southbridge(if it wasnt caused by an update).
According to XBH: Error within Xam

You don't have an Infectus but you are piggy backing the onboard NAND with the demon. I'd say its definitely soldering issues. Something probably worked itself loose over time.
