RGH Stopped booting to dashboard

[Mikaz]

Hi,

strange thin happended. Gliched 16MB Jasper. Everything was working ~2 weeks. Not I got this console back. Tried to turn on, few times CR was blinking green then stopped, no sighs of booting. After few tries it booted for 2s and freezed on xbox logo. After that it gliches but stops after 20-50s and doesnt boot.
Tried everything: changed wires, changed rezistor, rewrited nand few times. Nothing happens. Strange thing is that console boots to xell when turning on with eject button.

The only thing on my mind is that maybe CR is not working properly, but then it wount boot to xell?

Anything on your minds people?

Thanks in advance

P.S Already done ~50 RGH, this is first the problem.

Well try the obvious stuff first.

Flash back the retail NAND.

If you can get into Xell then that indicates that the CR is working as it should.

Have you tried to either create a new glitch build and load it? What happens if you reload the stock nand?

 

[keil423]

Have you tried writing back the stock nand to see if it boots to retail dash on that?

Is this your console or is it a customers?

Does the console ever give any error code (RROD)

LOL speed junkies above!

Tried retail nand - no luck.
Tried to new glitch build - no luck.

It was my old jasper that I sold to client. Yes, after one nand writing it got to 0022 (E10) error once. Only one time and gone after restart.

swap the coolrunner

Now i tried original nand. Doesnt boot up without CR, with CR it gliches ~20s and gets 0022 error.

Installed new CR - nothing changed. Xell booting fine, no signs of dashbord at all. Im not pro, especialy on hardware. Could it be hardware problem?

0022 is either a wiring issue or the wrong LDVs but with the 20 sec delay, I believe that points to a wiring. Martin C can say for sure. He posted some approximate times the other day but I don't remember what they were.

1st step = Check wiring/soldering again.
2nd step = follow Martin C guide.

had a issue like this not so long ago. I did what Krafter suggested, i read the pot by Martin C and turned out the LDVs were wrong.

worked like a charm

Approx timings for 0022 on stock NAND:

5s- issue with CPU_RST/CPU_PLL_BYPASS
15s - LDV
30s - GPU issue.

These are from experience

Thanks Martin. Maybe that would be good info to include in your 0022 guide? It might save some confusion for people.
