so far so good, the rgh boots to FSD 3.0 and stays on like before jut need to test with game play to see if it will stay that way. However we still have a problem with the standard nand, goes into a rrod instant, is it work loading the stock nand in jrunner again and re write to on board nand? no really any harm in trying, because the rgh nand works fine now just the normal one. Or should i create an fresh new retail and and write that over? Thanks

Sounds familiar...

Try this. Boot the Demon Nand. Turn off console with power button, and quickly switch nands with the switch, then quickly press power button. If it boots stock, good luck. Had the same 0020 problem on a falcon that was never resolved. Would only boot stock after booting Demon first. If I flashed both Demon and onboard Nand with stock, both would boot fine.

Tried that mate no luck there. So erased stock nand, created a fresh retail nand, wrote it back to the console and still same issue. Dont know why the stock nand is effected as until now it has never been tampered just read from only.

ok so think I have narrowed thie e79 issue down to two wires.

The orange kisok wire from demon to mobo has been taken off (leaving just the kiosk wire from r-jtag to mobo on)

Green wire (point 4 on demon phat install picture)

Green wire on, demon doesn't work or console wont power up no life in the console, power to the r-jtag is still there. The stock nand boots with no issue no E79.


Green wire off, the demon works but the stock nand goes to RROD.


Orange kiosk wire from demon is still not connected to the motherboard.

Its either these two wires or point 4 is causing issues with Falcon mobo

Taken from the tutorial: If you are using R-JTAG with DemoN Phat you need to remove the DemoN Kiosk (orange wire) to get RATER software remote power on feature. Simply remove the wire from the DemoN during RATER testing, when finished reconnect the wire.

The problem is with no orange wire on i cure the rrod e79. With it on, the console goes to rrod in stock nand.

With orange wire off and green wire off, console boots in stock nand no problem, but their is no life when trying to turn on the demon nand. You reconnect the green wire and the demon has life but the console goes to rrod. So cant win

Try turning on the console with the demon. Then switch nands while the console is on. The console will turn off when the smc reset is sent, and i will bet it boots. not a pretty solution, but only need to do it when the power is first connected to the xbox.
I had a falcon that did the exact same thing, and in the effort of trying to find a solution other then this, it over heated and stopped booting all together.

Another thing i have observed, is that no one had this problem on there falcons until the r-jtag came out, and in this case worked fine with rgh2. Just curious if the extra power consumed by the rjtag could be messing with the smc reset because the 5vsb isnt putting out enough power to power the smc reset, the demon and the r-jtag on the falcon.

You are spot on before you posted this message i was going to say i fixed it by doing exactly this. Maby worth me posting in the feedback/bug section as iv'e seen quite a few similar cases. This may be a fault that TX never discovered when creating the board and can work on this fault or even bring out an addon chip just for falcon users so they don't need to boot via the nand switch. Im going to post a video here on this method to show it works.

it's not a fault. You have a dodgy console.

Two entirely different things.

I agree, but just in case i have heard of at least 3 consoles all R-Jtag and Falcon, that have this problem with the demon. I would also like to note that the console worked fine with the same demon installed on RGH2. It is worth looking into.

Op try disconnecting R-Jtag board, and disableing jtag by turning switch off, and see if the console resets smc correctly. leave jtag nand on the demon and try switching between them, and see if stock boots without this trick.

This isn't something I've heard of before. Definitely try desoldering 5v from R-JTAG and then plugging in PSU, switching to stock NAND and then seeing if it boots.

since no one has heard back from the op. can someone else test the theory. I know scruffdog also has a console that does this. Any amount of data we can post about the problem the sooner we can find a solution. I would try with the one i had, but the board overheated and got RROD because i was trying to fix it, so i removed everything and scrapped the board. Also since I was the first that i know of who has had this problem, I had this problem back in june, and it seems to be recurring i am very interested in a fix for this problem.

If i had more falcon motherboards i would do the testing myself, as the only console that has come through in a while is a zepher, and i am skeptical about even attempting R-Jtag on it because of all the problems zephers have requireing a reball.(Dont have $2000 for a BGA table, and the only console i attempted a heat gun reflow got worse)

I didn't know it was the exact same symptom.

I have an R-JTAG Falcon here but no DemoN for it, otherwise I'd have tested.

What I'd definitely check is giving the R-JTAG an external 5v supply.

I dont mine anymore. Someone bought it from me, even with the issue it had. They said they could deal with a quick switch to get to stock if needed. I have a couple falcons that need a reflow on my rack. Once I get my station back up I will rjtag and install a demon and see what happens

Hi all sorry been at work today so could not reply. I will try both suggestions tonight and post back the results.

*Martin C: Were else nearby on the board is their a 5v feed? Im using the 5v feed from the nand point next to the Hana chip were the qsb v3 normally goes.
