RGH Middle green light flashing, no boot

[webhdx]

Hi,
I've been using RGH'd xbox for a long time. It had problems with booting but I was too lazy to fix wiring and instead I've been hitting xbox so it would boot. One day it stopped working at all (middle green light flashing, no video). Mtx Glitcher is probably fine since I was able to reflash it.

I don't have original NAND but tried generating one from donor SMC, it won't boot either. I can't boot to Xell with eject button. I've already tried HDMI and composite cable. It's probably hardware fault but I can't diagnose the problem since there is no video which means no error code.

How can I monitor boot process? Is there a UART for such purposes? Any advices?

// EDIT: I flashed Retail image and middle green light blinks for a few seconds then 3 RROD comes in.

Are you using any Tx products in this install? Starting with "I was too lazy to fix wiring and instead I've been hitting xbox so it would boot" probably isn't the best method. If you want to measure boot process you will need Rjtag (for phats) or CR3 pro to monitor POSTOUT + JR-Programmer v2. The southbridge has UART but this is just for recording Xell data once it successfully boots.

What kind of info R-JTAG would give me? It costs 100PLN which is expensive in my country since I can buy used, working Xbox360 for like 300PLN.

Please fill in this template. http://team-xecuter.com/forums/showthread.php?t=96474 . Lthough without any Tx products being used there is very little help that can be given. It's likely the wiring has failed and now you have flashed a wrong NAND image to your console. What is the secondary error code of the RROD? U would have been better off reading what was on the NAND and created an image from that. Even though it was probably wiring related and nothing to do with the NAND image.
