- Install CORONA QSB CR UPGRADE and read original nand
- flash DGX image
- Install DGX
- Get key
- Create glitch image
- Write Original!!! nand in console!!!
- Remove DGX
- Install CORONA CONVERTER QSB
- Install DemoN - Using this guide (http://www.xecuter.com/forums/showthread.php?t=97468)
- Install Coolrunner C

Then I write original Nand in Demon, further created earlier Glitch image in the console.

Using this guide (http://www.xecuter.com/forums/showthread.php?t=91140) I program Coolrunner C (Corona 48MHZ + Demon Installed)

As a result - Only Beep Sound, аlso doesn't start.

What do I do not so? I think my mistake in programming Demon & Coolrunner C! Help please! Thanks!

Why didn't you solder E & F to the pads on the QSB??

Have you checked for continuity between the console NAND and the QSBs on the DemoN?

Have you checked for neighbouring shorts?

Write original nand to console, and Glitch image to demon. the coolrunner is turned "off" when the demon is off, if you wrote the demon coolrunner file. if you can read and write both nands with the demon, then i would think your soldering is probably sound.

i got the impression that since it beeps, it was turning on, and was thinking it was more of an issue booting a glitch image with the coolrunner disabled.

- When i install DGX & start console, debag quickly blinked and there was no sound from 48.000Mhz Crystal, I solder E & F on Back side and get the key.

- There was a problem in attempt write any Nand in Demon ( manufacturer for code AF not found), i resolder all points, after that all - OK!!!

- All points on Demon and a Board I resolder on 3 times, but to check QSB which is under the Demon I can't...It is necessary to remove the Demon for check

Now i take the Nand X and write original (nandump.bin) in to console, then i start read nand from console with the Demon. The first time was read OK, but in second I saw - Header is wrong..

"console does not boot after install demon" looks like improper soldering to me. should be shot somewhere. happened to me when i first tried install demon.

OP - I think you're at the stage where you need a pro-installer to look over it for you. DemoNs are for pro-install anyway for good reason. For example, you didn't have to write anything to your console's NAND.
