i have an interesting idea and a request ill start off with the request.

1) Does any one have the pin out for the DemoN add on solder pads? im curious as to what they do or what they might be manipulated to do for add on LED's or a USB port or something to that effect. A DIY add on would be cool to see.

I was inquiring in the general section of the forums about a way to add a second HDD and some one pointed me to the SD/USB thumb drive mod for slim consoles ( http://team-xecuter.com/forums/showthread.php?t=96296 ). I find this to be very interesting due to the fact we can have 2 "internal" (so to speak) HDD's for our slim 360's . One that only the RGH/Fusion NAND can see and the other for legit XBL purposes. How ever this mod (at least to my knowledge) is not workable for a phat 360 as it does not have the pins to connect the USB device to that is contained in the slim 360.

My question and/or idea or at least something to bring to the drawing board for some one more advanced than i or perhaps xecuter them selves can make something out of.

Would it be possible with the pin out (if released or available) for the DemoN add on points to some how add secondary internal storage like that on the slim? an add on USB interface PCB or something to that effect?

This extra internal HDD is what really makes the Slim 360 THE ideal 360 for a DemoN install due to the fact the 320GB HD capacity can be broke and you can still also have a legitimate HDD for the legitimate NAND all in one system, where as this is not really possible with out HDD swapping or using sloppy external HDD's for the Phat systems. It might also possibly be of use for adding even yet another USB point to the slim 360 one to add an extra external USB port and one for an extra internal HDD By using both the DemoN add on/Mod AND the internal usable solder points in the link above....OR for adding the USB connection to the systems that actually have the 4GB internal storage.


again this is just
a) a request for DemoN Pin outs as im curious what kind of modifications can be done with the add on pads.

B) an idea i have been contemplating for a day or so now about how to not only have dual NAND but dual HDD's one for each NAND as to not defeat part of the luxuries of an RGH system with a demon installed

I've just finished my first demon install in a jasper, it's an awesome little thing,
I would be very interested in a auto switching dual hdd solution for it.

isent there a 360 phat arcade model with 512 MB onboard storage? what motherboard revision is this? i wonder if the pin out for it exists on all phat mother boards as well just like on the slim models.

Not a bad idea. This could be done with a stand alone circuit using the EN from the CR for the output to switch..... You've got my wheels spinning on this. Maybe this can be a nice project for me.

ya i have no education on ciruitry i normally just follow directions i figured some one here might have a bit more education than i and might be able to tell me if its even doable.

the whole reason i was thinking about just using the add on ports for the DemoN would be to have the second HDD activate when the DemoN turned on and it would initiate it and thus being only seeable via RGH/DemoN NAND but if u used the CR then it would have the same outcome as well i suppose

i sent a msg to xecuter also with a link here proposing this idea as well.

the one I did was a 16 mb one, small block nand,
from what I've read the 256 and 512 MB units just have a larger capacity nand chip and use part of it for storage.

Correct. Not lokebthe trinity. It wouldnt work the same way. Would have to wire to the memory cars ports if even possible or switch with hd.

Sure it would. If you put a meter on the EN point you'll find that it goes high with the Demon NAND and low with the stock NAND selected. The circuit would switch drives based on that.

hmm then some how make the "internal" propiatory HDD port function with that? like i said im not familiar with the pin outs or circuitry here....but id imagine there is some way to make this all function as one solid unit with 2 "internal" phat HDD's one for RGH and one for stock.....

EDIT 1:
there is that molex/wire harness inside the phat hdd enclosure seeing as how the propitiatory HDD connector is mounted right to the mother board that perhaps a small relay could be spliced into or something for a switchless mod?

EDIT 2:
What kind of interface does the memory card readers run on? i know the xbox 1 controllers and memory cards all used USB 1.0 or 1.1 or what ever it was...but what about the 360.....we do after all cover up one of the memory card ports with the DemoN switch during the install....not like there really used now a days any way due to the ability to use USB media in its place.

also i found this in a google for the 360 pinouts it may or may not be accurate depending on the mother board revision.
http://dwl.xbox-scene.com/tutorial/Xbox_360-HandC-V1_4.pdf

some one with a better understanding want to go threw this and evaluate our options and/or draw up something that we can begin to elaborate on here? i think were getting on the right track im just one for clean efficient and one solid uniform as stock as humanly possible look. i try to avoid 3 way switches case cutting and things of that nature as a good mod always looks like it belongs in my opinion.

EDIT 3:
look at the thumb nail i uploaded it does as a matter of fact look like the Memory Card slots use some kind of USB like pinout....so that means that we could in theory connect a USB female port for example to it. or cut one of the traces or something and use the CR as a relay/indicator switch when to engage the mod on the RGH NAND.....now seeing as how this kind of thing was done (the USB interface for the controller ports and controllers) on the xbox 1 i would imagine the size limitations would still apply some how even if you tried to format an external HDD mod having it register as a memory card.....how ever im not sure if this would be true or not in RGH mode as i have no RGH to test with. Would some one else with some soldering skills like to try attaching i dont know maybe a 4GB USB thumb drive via some kind of mod then maybe something that surpass's the now 32GB limit for external devices and see how this reacts via Legit NAND and RGH NAND and report the finding back?

EDIT 4:
After further exploration of the slim mod i notices one difference between the weird Memory card USB like interface on the phat 360 VS the slim USB add on mod....the memory card slot on the phat 360 only provides 3.3vdc where as according to the pinout on the slim mod an external USB device requires a VCC +5v source......my personal solution to this or idea behind it....cut the 3.3VDC trace leading to the Memory card slot and perhaps run a jumper wire from a USB port on the front of the motherboard to the correct corresponding pin. HOW EVER if there is a VCC +5V output source on either the DemoN or the CR instead of running a jumper from an already existing USB port run it from one of these devices to the corresponding pin...thus turning the external storage on and off when switching from legit NAND to DemoN/RGH no switches no relays just a good clean on and off source....perhaps with some sort of one way diode ( i think thats the component that only allows the current to travel one way) to prevent back feed or damaging the CR/DemoN.

EDIT 5:
again upon further reading i have noticed that ALL of the USB +5v sources on the phat 360 are +5v VDC.....HOW EVER all of the standard pinouts for USB even the pin out for the 360 slim USB mod has +5v VCC......i am going to assume this is of no real concern as the 360 phat is still compatible with any standard external USB media device......how ever i would like to note this fo further investigation if the need arises or something occurs incompatible or other wise.....im also curious if this is how the 360 determines the size limitation (32GB as of the latest dash update from what i have read) of an external device for storing the profiles and such. How ever i have 2 questions arise from this as like i have said i am not knowledgeable on circuitry:

1) can some one define what the difference is between +5v VCC and +5v VDC is so i can better understand what i am looking at.

2) if it so happens to be that this is in fact an issue with any size limitations or other issues, would it be possible to convert the +5v VDC to +5v VCC to circumvent it via a simple circuit of some sort?

EDIT 6:
Would have to wire to the memory card ports if even possible or switch with hd.
this brings me to recall one specific thing that i remember the datel VS microsoft lawsuit over there memory cards that supported micro SD cards up to 32GB:
http://www.geek.com/articles/games/...-rendering-its-memory-cards-useless-20091124/

this means that at one point in time in the dashboard history of the 360 there was no limitation of the Memory Card slot capacity wise. This brings to question if that capacity limit is also removed with freeboot the same as it is for the standard HDD installation, and if it is not how if passable do we disable it ore request that the freeboot devs disable it (RGH still uses freeboot same as the JTAG if im not mistaken correct?)

i have a falcon on dash kernel 2.0.13599 (July 19, 2011) the dash kernel that disabled 3rd party memory cards was 2.0.8955 (October 23, 2009) this means that dash 2.0.8507.0 (September 23, 2009) was the last dash to support 3rd party memory cards and quite possibly no size limit on them (SDHC Micro SD cards only went to 32GB i believe).

seeing as how RGH uses a completely different exploit that exists in any console with an HDMI port (and even in a xenon to recover a DVD key) i was curious if i could find a donar NAND with that kernel and roll back to that dashboard and build an RGH1 NAND with it rather than a recent dashboard. All of this is ONLY if the third party memory card limit is not or can not be removed from freeboot. This SHOULD enable the use of external storage media along side rewiring the memory card port for a USB port.

All Dashboard information was obtained from:

See my solution for separate HDD and USB in Live and in RGH mode, works great!

http://team-xecuter.com/forums/showthread.php?t=98249
interesting approach...even tho that involves a slim and im trying to resolve some kind of solution for the phat its still nice work none the less.

im curious as to why you chose to use the SATA interface directly rather than using the slims onboard hidden USB mod as spoken about here: http://team-xecuter.com/forums/showpost.php?p=715820&postcount=5

my ultimate goal in the end of all of this is to come up with a secondary HDD that only the RGH NAND will see when using it, a lot like the mod i just linked up there.

i have also seen and been directed to another mod really close to what you are talking about here: http://team-xecuter.com/forums/showthread.php?t=85491

either way i am trying to seek some kind of solution that can be implemented to not only look cosmeticly correct but also targeted toward phat consoles seeing as how the phat 360's completely lack the pin out that slims have for adding a USB device as mentioned in the ULTIMATE Slim Trinity Flash Memory Mod i linked above

on a side note i hate things that dont look cosmetically correct like switches and yes even the external DemoN PCB, it would be so much better with a plastic enclosure to make it more uniform looking. Appearance and cleanliness makes any mod so much better in my opinion and when i install my DemoN i will be looking for a way to hide the external PCB or at least fitting it to a project enclosure box to make it look more uniform.

I was thinking use the standard hdd port, would it be possible to have 2 hdd's on the same data wires provided only one of them is powered at a time.
possibly use some sort of electronic switch, to switch power from one hdd to the other with a few milliseconds delay between powering one off and powering the other on taking it's switch signal from the demon nand select button.

that way we could modify a side caddy to hold 2 hdd's.
I'm probably way wrong, I don't have a clue when it comes to designing circuits.

I like the side caddy idea.... all you would need to design would be a side caddy that holds 2 hdds, and has a built in switching circut that switches both sat and power between the two depending on the nand. and instead of a switch you could add a relay that is connected to the coolrunner/demon en pad, so it switches on when the demon is on, and off when the demon is off. and if you are really good you could even program a chip to do it, and cut out the relay. just a guess.

Now that the sonus 360 has hit the Phat, I think it would be cool to see a way to program the sonus from the demon...... it just doesnt seem right that i would have to take the console appart every time i get bored with my sonus sounds, and with the demon installed, i already have an external usb port....... this would probably only require a firmware update, and some wires attached to some of those extra points, i would think. then you would have your nand, coolrunner, and sonus programming all in one place. just a thought.

i know this thread is old....but i have found some sort of solution i think.....there is an instructable here: http://www.instructables.com/id/XBox-360-Memory-Unit-USB-Connector/#step1

in that tutorial it shows how to add a male USB end to a official MS MU for a phat 360..... how about we take his instructions and modify them a little...take the wiring and the regulator....wire it to the 360 MU port from the motherboard and replace the Male USB end with a female USB port instead. mount the USB port some place and try to format an external HDD or SD card or some other device and see if it is detected as a memory unit.

any feed back thoughts or suggestions?
