I used Jrunner and Coolrunner to attempt to RGH a Zepher that I have. For some reason the RGH failed. Never got into Xell. Anyway, I just want to reflash and return to retail xbox. After flashing my nand backups back on the box it doesn't boot. Just a solid green light and no boot. Any idea why and how to fix?

Why? Possibly because you no longer have a proper copy of your retail NAND and overwrote it with an ECC version of your NAND.

You've not provided any proper information - we have a template in the noob section (where this is being moved to). Please fill it out with ALL information.

You probably forgot to plug a video cable, or flashed something else rather than your original nand dumps. Otherwise it would have booted up.

Ok, here's the complete story. I followed several guides. I dumped my original nand 4 times and compared to make certain they were all good. I created the ECC file and flashed it. It wouldn't glitch to Xell. I flashed one of the original nand dumps back to the box and desoldered the RGH chip. When I attempted to boot it up it worked but all I could see were the solid colors on the screen (squares and rectangles for background). There was no text on the dashboard. I downloaded the latest dashboard and put it on a USB drive. When I plugged it in the poppup came up that would normally ask me if I wanted to upgrade but I only saw shapes and colors, no text. I attempted to guess which buttons were the right one to confirm the upgrade. It didn't seam to work so I tried to flash one of the original 4 nand dumps back to the box. That's when I ended up with the solid green light and black screen.

Dump this motherboard, it's not worth the hassle. If the update you applied burnt CPU e-fuses you won't be able to run that 4 nand dumps anymore, but you should get RRoD 0022 in 30 seconds. About rectangles without text, I've never seen this. Green snow on the screen is a symptom of upcoming E-74, but squares and rectangles... :crazy:
