RGH Reset Glitch NAND read problems and possible brick?

[kdmstr]

As you've requested for it martin I've opened a new thread and quoting all my recent posts in here.

Isn't there an extra pin for the slims? Anyway I got slim board and my readings are.

1) 0.15V
2) 3.29V
3) 0.16V
4) 0.00V 0.03-0.04 Ohm (20k)

*The pin next to number 3) 5.16V

5) 3.04V
6) 0.00V 5.96 Ohm (20k)

I have been soldering and desoldering like 20 hours. And still got no results at reading nand. I have installed CR and programmed it with my nand-X too. But I couldn't read my frikkn nand. I've used QSB( which is hardest to install for me), pin headers, direct wires. But still "can not continue" error on nandpro3. And if I try to use nandpro2 then it says wrong arm. And also tested on 3 different computers. That thing is driving me crazy. Aaaahhh

yeah I've desoldered everything including the coolrunner, I'll take phtos now

This is my first time and I've recieved my goods 3 days ago(nandx and slim bundle) and have been trying to figure this thing out. Like I said tried on 3 different comps. 2 of them win7 1 of them winxp. I'm still trying to find my usb cable to transfer photos. Brb in a moment with photos I hope.

as close as I can take

Thnx martin I will try and post the reports again.

Now I think I've bricked my xbox. After some multimeter tests. I connected xbox to my tv and tried to open it. I can hear the ding sound from console but its not opening. I really dunno wtf has happened. I think I'm done with this. Need pro help. I wanna send this to someone if its repairable. Thanks anyways

You mean the coolrunners orange cable right? It's already desoldered and r3b15 looks fine.

Ok I've taken pics. Near hana chip and nand pins again

Edit: And btw my multimeter is broken too lol. It show abnormal values. I'll try to find a working one

I will test it as soon as i get a new multimeter thx martin

Hi again martin I got my new multimeter and got the readings again

1) 0.13v
2) 3.27v
3) 0.07v
4) 0.00v 0.04 (20k)
*) 5.13v

5) 3.00v
6) 0.00v 5.80 kohm

and like you said tried to measure the r3b15 resistor and the result is .033 (2k)

so what should I do now

edit:
Current situation
I still only hear the beep sounds from console but it doesn't turn on just keep beeping when I press the buttons

That's it. That's the story of my life.

Did you ever get it working in between soldering the QSBs and now?

Was it working before you started?

 

[kdmstr]

yeah it was working perfectly fine with 0225 lt+ 2.0 on it. Haven't tried to boot the console after opening it. When I fail to get the nand readings I reassemble to see if my console is working (with programmed coolrunner installed on it) it didn't work after all these operations and like I said I removed the coolrunners wires and tried to boot again and still the same result.



EDIT::: HOLY FUARK!!! I dunno wtf is going on but I hit the button one last time after 10 mins with desperation now and fans started working I will connect to tv to seee if everything is ok. Damn I am so excited right now. BRB with the results

 

[kdmstr]

Now we're on another part damn. Xbox is working but not showing on tv. I can open it via gamepad and buttons, and eject button is working too everything is fine but there is nothing on TV. I've tried both hdmi and scart.

seriously wtf is this a touch of god or smthn. I couldn't find a reasonable explanation for this. How can my xbox magically started working. Maybe I've done something with the probes again when I was trying to get the readings

 

[Martin C]

so unplug the DVD drive and HDD, then try to boot it.

lol ok now I can see it so what should I do now.

The problem here is, as most cases in RGH, your soldering.

R3B14 and R3B15 have either been damaged or displaced from their solder points, which is why

a) you couldn't turn it on or read the NAND (R3B15)
b) it won't boot with the DVD drive attached (R3B14).

Flux these resistors and reapply an iron to either side. Make sure they have proper contact. Once done, first turn on to make sure it still works (prove R3B15 ok) and then try again with the DVD drive (R3B14).

If both work after this, your NAND should read/write ok.

 

[kdmstr]

I think I'm in love with you martin damn your answers are always reasonable and fast. I will try again and post the results later.

I think at first when I was trying to read my nand, the r3d15 point was not working and my console not booting. After trying to read the resistor with probes I somehow touched something and fixed that point. So now my console is booting and I should read my nand I think. Hmm everything is much clear right now.

And BTW should I read the r3b14 resistor? should it be 33 ohm like r3b15

 

[Martin C]

If you get a reading, then it should be ok. Resistors don't give false readings, so it's either something or nothing (blown).
