Help needed with R-Jtag and Falcon

[A.D.I.D.A.S]

not an electrician but I took my multimeter out and threw it on 20 V DC and I get 1. on point 1 of your diagram.

scratch that....I had good leveles but 3 was a little lower than what you indicate it should be at

post your values and measure the resistance of the other 2 points should b 6 in total

post your values and measure the resistance of the other 2 points should b 6 in total

point 1 = 3.3v
point 2 = 1.02v
point 3 = 3.3v
point 4 = 0.43v
point 5 = 3.3v
point 6 = 3.3v

Obviously something isnt right. I have power to the xbox but xbox is not on and these are the numbers Im getting. I have read the nand 4 times once but now it just errors out.

Also the Nand-x is still connected to the board

look at this thread again

you are measuring voltage on points 1,2,3 and 5. Points 4 and 6 change your multimeter to ohms. Make sure you are grounding the black probe then rerecord your values.

point 3 = 3.3v
point 4 = sometimes I get 33 sometime I get 85 ohms
point 5 = 3.3v
point 6 = not getting an ohm reading

OK, Im about ready to pull this out. Now the jr programmer is not beign detected by my computer. It was working all day yesterday and this afternoon.....grrrrrrrrr

Either your not matching the points up right or ur readings are not what they r supposed to b. maybe Martin can help you from this point. Just double check your board for shorts or little pieces of solder that might b there by mistake.

points 1 and 3 should not be 3.3v. Read my sticky again.

If they are def 3.3v, unplug the PSU and check for continuity between 1 and 3.

Does it matter if the Nand-X is installed to the board? I wouldn't think so but have to ask. So just unplug the xbox from power and then check continuity between 1 and 3?

 

[A.D.I.D.A.S]

Where can I but a new Nand-x chip. took it out to check the underside and there is a pad missing.

 

[scott1503]

New nand-x or jr programmer ?

Both can be purchased from xconsoles, ck3 pr mod traders or any of the other suppliers in the list of where to buy on the main site

 

[A.D.I.D.A.S]

just the nand-x But if I cannot get my computer to see my programmer I may get a new one too. Yes I have tried all the driver workarounds its just not seeing it.

Post a pic of the nand x with the missing pad

I have that same problem on a zepher with dash 15574

flash config: 0x00000000
error cannot continue

im going to reinstall nand-x to see if that will fix it. im having no power issues although i am using a different power supply than that of the original.

ANY HELP REGARDING THIS MATTER WOULD BE GREATLY APPRECIATED AS I HAVE BEEN WAITING A LOOOOOOONG TIME FOR THIS!


new info:

re-soldered NAND-X all my pads were fine however the error has now changed to this:

version:00
error
wrong version
cannot continue.

 

[davyboy]

flash config 0x00000000 prob your wiring use Martins connection guide, post pics

When you entered this section of the forum, you would have been forced to read the template. You've completely ignored this and now thread-jacking to get help for your own issue.

Please read the rules and start a new thread, completing the details of the template in the process. Read the stickys before posting anything else too.

[davyboy]

He means start your own thread using template supplied on this forum it asks for mb type, dash.was it working etc, what you have done in this case is add your problem onto someone elses thread.

 

[A.D.I.D.A.S]

Sorry for the delay in this but had to step away before I threw my xbox threw the window.
I have started fresh with a different 360 and have everything installed, this is still a Falcon, My computer (Windows 8) has detected the programmer. In the process I accidentally started the 360 with the r-jtag installed and after I quickly powered it off it will not start again. I was no able to read the nand. I keep getting the 0x00000 error So I'm thinking it's a soldering issue with the Nand-x.

Any other suggestions?

Thank you

you'll need to post images etc as per our templates.
