Thanks Antalpromille you made me laugh at least !!! Antalpromille is write lets leave the image building alone for now
How did the post fix adapter fit over the XGPU. can you measure the Resistance from pad five on post fix to ground should measure 55 to 60 Ohms
and just like Antalpromille stated do you have another CR-4 to try

Have you tried different dip settings? It might be worth trying, if you havnt already. it also might be worth trying to build a glitch2m image(Probably wont help, but it cant hurt to try)

thanks for the advice guys. Unfortunately I dont have another one until xconsole ships me another and I was almost thinking something might possibly be wrong with the cr4. I tried dips 3 and 4 but I'll try the rest after this post. I also flipped all the switches on the bank to make sure none were stuck halfway from the factory but ill hit the dips in a minute. and thanks for the input antalpromillie. Vegas i know im going to sound stupid but I dont know how to measure with a volt meter.Do you think you could give me a brief description on where the dial should be and should I check the ohms while the console is running or off with the power brick plugged in? I will also try the glitch2m in a little while if all else fails. Also CHECK OUT THE VIDEO just got done uploading basically its running at the beginning of the video and I turn it off with the controller then start it up with the controller and thats where you see it red ring. I paused the video and tried again it red ringed then tried again and it booted thats when I started filming again.

Honestly im not sure....does that make a difference? Think i might have fixed the issue I have 5 successful boots so far and right before I refreshed it would red ring exactly 2 seconds after the 4th time the green led lights up

Sneak a look under the Heat sink read the ram is it wind bond 2-k or samsung I also had one slim corona stop glitching wile using Rater at the 5th cycle every time because of image build troubles
does it not sound like the Kook from Germany who struggled with his windbond Super slim
his post
But after I made the Xebuild Image and I flashed it into the box, the Box will not start !
The chip makes blink blink.
is there a special way to get the winbond2k models to work with the CR4 XL ?
After 2 - 3 mins of blinking the CPU fan goes fast and console turns off.

What can I do to get the CR4 work into the winbond2k Model 4 GB ?

I can see you have ribbon cable connected to qsb. Did you try to boot console without ribbon cable? I used my last QSB maybe in 20+ installs and last few xboxes were freezing on xbox starting logo until I desoldered QSB (my qsb looks terrible - bunch of wires soldered and glued together :D , had to improvise, my reseller was out of stock). I don't know if desoldering qsb will help, but try that without ribbon. It will take a minute to try :)

If it boots most of the time with out the rrod, I would call it a difficult console, and tell the customer if it does that to turn it off, and then turn it back on, and it should work.

Its not for a customer its for my son but Im just trying to figure out if its something I soldered or hardware failures with the xbox but it wont give any error codes just shuts off after it flashes four times
