i have 2 slims here that for some reason do not want to dual nand, i have multi metered them and had them under microscope each pin is joined and no resistance between them, the bottom original nand reads fine, top nand it just comes up cannot find usb device on nand pro, i have tried 3 different nands (all removed from working consoles) and they all do the same, i even run extra 3.3vv to pins 12 and 37 and still the same, all points are testing out fine with multi meter and i just dont know what the hells going on

either i have 3 dead nands (they were pulled from consoles that were working) or the boards are unmodable (they are early 2010 model slim trinity)

Guys, I have a question about the dual boot.
How to set up my content?

I mean, I just turned a stock 250GB Slim (DVD stock firmware) into a dual boot with cygnos v2 rev e and X360glitch. The Slim itself is still stock since the RGH NAND image is on the Cygnos NAND, so when cygnos is turned off, the Slim run the stock NAND. But the deal here is how to set up FSD and all the JTAG content like homebrews and its respective profiles?

I have a "feeling" (hehe) that I should not mix them like having only my internal 250GB HDD to accommodate the FSD, JTAG content, stock live profiles and RGH profiles.

Should I have two HDDs and switch them everytime I switch between stock and RGH or just one HDD with everything is fine and Live safe?

Of course I will not use the RGH and JTAG content to go online, even if it was possible, I'm just trying to be "safe" with my Live stock part of my dual boot.

Any thoughts?

Thanks!

No. 10k resistor + 3.3v to pin 9 (CE) of the top nand, straight 3.3v to pins 12 &37.

I'd like to thank you for this info it was so helpful..I've been up 60 hours straight racking my brain and this solved the problem..However I'm hoping you can shed some light on a new situation I have.. This procedure programs my top nand with no problem, and my switch is setup and dual boots..However when I'm in glitch mode the fan speed runs at what sounds to be like 100% but in normal retail mode the fan runs normal..I'm testing on a slim and my nandwich only has pins that need to be connected and the rest are broke off.

For the life of me I can't seem to figure out what's up with this fan..

Edit: Ok so it turns out just xell the first time loads like that...Once flashed with the glitch image fan speeds go back to normal and console dual boots..However when I read with usb programmer I have to hook up 12/37 to 3.3v everytime but I don't ever plan on use that again so it's ok I assume.

Hmm all very interesting however have no access to any form of dual nand board but it seems to me to be an easy development to produce a dual Nand PCB with both Nands fitted to the board this would render the onboard nand useless and may be removed.
I know this sounds a bit OTT but the same board would work in all xboxes and would not require any track cuts to be performed.
simple to install using the well listed alternate points on the board. A lot easier than sticking a nand on top of a nand and safer if all goes wrong. With no track cuts its easier to revert back to its original condition no need to bend pin 9 and wire to it.
only downfall is i have no PCB design software and no clue how to use said software so if anyone wants to design it and post please do. it can be accomplished on a single sided pcb therefore can be developed at home and the cost of the replacement Nand chips is less than £6 for a pair so would be a great improvement on current solutions that are expensive and out of stock at most places.

Urgent quick update for everyone.  My Dual boot setup died on my Slim after this new update today.  but the odd thing is that not only did the cygnos360 nand die on the Slim but after the update my stock Dash doesnt load.  I will report my findings as to why when I can.  I think it may be because my glitch board is always on so maybe it is causing problems with the stock dash that just updated.  very weird.  so this is my warning.

[thugsters]

With the recent XeBuild release are we able to setup a switch or some sort to disconnect the glitch chip on normal nand boots? I have all my slims updated to dash 14717 but on my dual nand systems only the glitch dash boots. I can disconnect the glitch chip's vcc and have the normal dash boot, but seems I may have to figure out how to wire a different switch in or ground it out differently now.

[Antman1]

if it is a Slim I would say yes but you will need to have a relay that will turn the glitch board off when you select the Live nand and you will need to rebuild the Reset Glitch nand to load.

I finally got around to fixing my MW3 Slim with the Relay to turn off my glitch board and figured I would post pics.  I can confirm that you can update your Dual boot Slim Trinity Consoles and get them to Glitch again if you have the relay installed like in my diagram.  I was also asked were to put the relay when you install it and I am showing a pic of how I put mine.  I used double sided sticky tape to keep it in place and I am please with the results.  It is completely out of the way.  

Here is how I installed mine in my MW3 Slim Trinity Board:

Awesome! I installed my relay under the hdd plug where the red square is, but ever since the 14717 update my rgh seems to take longer to boot, does anyone else notice a difference?

[Antman1]

I actually made my boot times better because with the relay installed I was able to deposition my CPU_rst wire to boot quicker.  Boots within 20 seconds

OK which switch do I need to enable \ disable the glitcher the same time as the hacked nand, like in the following picture:



I found two on ebay but i'm abit confused by the on-off combinations.

On-On here

or

On-Off here

Which one do I want?

UPDATE: On-Off Has 3 positions On-Off-On so I don't think It's this one. I take it I want the On-On correct?

I have the On-On switch and want to do this mod on a spare Falcon I have for my son.  Do I just need the 1 10k resistor like the diagram?  also for the glitch board to turn off with the switch do I solder the ground wire like in the diagram?  Will the mess with the switch for the nand that way?

[Technitian3]

Follow the diagram and it (should) work. Nand1 gets 3.3v + 10kohm from the mobo, so you only need the resistor for the added nand. As long as your switch is DPDT (double-pole, double-throw) it won't mess with the nand when switching the CPLD ground.

Thanks technitian3.  My office looks like 2 xboxs puked in here.  lol.  I pulled the tsop from a dead xenon and put it on my sons falcon and all went well but the second nand kept showing corrupted when I would try to read it back after 0022 errors so I redid it and now I'm out of que tips to clean the flux off.  looks horrible.  but it is detected and I am flashing it with nandpro parallel connection now.  hope I am done.

[Antman1]

looks like I screwed up.  I was trying to do the nandwhich mod and I thought all was going good but I couldnt get it to boot and reading the nand back always showed it was corrupted.  then I broke the "CE" pin off my second nand so I was going to give up and apparently I did something to my stock original nand.  I have checked for bridged points and I have none.  I pulled the TSOP off and cleaned the points then put it back on cleaned it up a bit and still acting like a corrupted nand.  I believe I may have applied too much heat the last time I removed the TSOP.  

Does anyone have a link to a place I can order another tsop chip?  I am out of dead 360s to pull them off of.
