FIXED CR4 XL and Demon Not Booting

[Krafter]

The wax paper trick is great but it's still a pain in the ass at times to work it in and around SMDs. I only remove them as a last resort as I suggested above but it's looking more and more like the best answer here.

You can also test connection RB at the demon remove the green wire from the demon. Then close to the RB connection at the motherboard you will see resistor R2T1 Check from the green wire removed to one side of R2T1 should yield 2.2 ohms
Wax paper thats cool no Felonies I hate removing the Demon will try Wax paper if I have to do it again

Sometimes, excessive flux can creep under QSBs and cause problems. I've seen this on more than one occasion. Only remove the Demon as a last resort because they are a pain in the ass to do so and easier to rip off solder points.

Something is shorted out if you just get the beep beep!! In the same row that you get 5 volts for the CR-4 you should be able to test for basic 3.3 stand by voltage
I dont see a picture of your voltage header ..You removed the REv-c so the old 3.3 pin you removed to power the rev-c thats 3.3 test it do you have power
Any of the small 10.00 ohm resistors x-8 that test differently any incomplete connections in that area can also cause what you are describing

Its got to be a solder splash somewhere. Check the nand on the demon itself for any stray solder on the pin's.

Otherwise try the alt wire install for the suspect point's on the demon.

Your soldering really does look good. i have had this happen to me with the same error and it turned out to be one of the qsb point's on the demon. I did a alt wire install to its adj, resistor on mobo and also cleaned some solder splash on the demon's nand that may have bridged the nand point's.

Otherwise i don't have anymore suggestion's beside's remove it all very carefully and start over.

i would get some wax paper,and use it to slide it under the demon points as you heat the point with an iron,and slide the wax under it one point at a time.works great.and id start over,as krafter said its prolly points under the qsb where you cant see em,bridged.

Thank you very much for the comments. I've found this: http://imgur.com/34VRrv8

When I touch these my multimeter says its bridged (it beeps) I am trying to unbridge them but its still bridged I tried the wax paper trick and nothing.. Any suggestions on how to unbridge this?

 

[Krafter]

When you say you tried the wax paper trick, do you mean you removed the Demon? If those points are bridged and there isn't any visible sign of a bridge then it has to be underneath the Demon in which case it will have to be removed, cleaned and refitted.

So I manged to unbridge the points, but I didn't remove the Demon. So I gently lifted the demon up and cleaned the points, THAT WORKED THANKS!. But now when I try to boot my console, it only boots the Retail side. Not the demon, the demon still doesn't wanna boot, no fans spinning up as I mentioned before. When I try to write an image with JRunner via the mini-board (with the blue led) on the demon Flash it says: http://pastebin.com/BVKDwwSs

Why am I getting this error, and can I write an image via the Micro USB on the demon when set to PC? And no Xbox PSU Connected? Will This Help?

Thanks btw

Are you getting continuity on those 2 points to there resistor/nand point's on mobo now? If not do a wire install for those point's. You may have pulled the pad's on the mobo while unbridging them.

You most likely won't be able to write to the demon anyway you try and have it actually boot up anything until you have all those point's connected.

Why don't you try doing the alternate wire install from resistor on mobo to pad on demon for those 2 point's? Then see if the demon is able to be written too

A few hours of sleep did the job, I didn't do anything, I woke up, Launched JRunner toggled Demon nand and it wrote... So I disconnected the Mini-USB plugged in the RF board,and it booted! So I turned it off and wanted to switch to retail mode, but when I pressed the miniboards button the blue LED Started blinking and when it blinks I can't boot, the xbox keeps beeping and no fans spin up. At random moments the LED on the demons miniboard turns on and off, when the LED Is solid(not blinking) it boots demon side, but once I press the button on the miniboard it starts blinking, and you can't make it stop until you unplug the PSU. Does this have to do with the connections?

Looks pretty good. The D6 point looks like it may not be connected. Did you check for continuity on the demon? Did you try cleaning the flux and check for solder splash's? Maybe clean the whole area where demon is installed and adjacant. Then see if it boot's

JR log would come in handy too.

Touch up d0 too...

Next time group the images in an album, pain clicking each one in turn! Still dont see the log (on a mobile though so easily missed)

For diagnosis, you can flash stock to demon. Rules out your image.

Update the fw on your demon to 1.04.

Check for continuity on the demon point's. Touch multimeter to demon point to adj. resistor or stock nand and see if they are all connected.

Use this as a guide. One of your points or more is bad.

Also maybe reseat your cable's too.

Yeaahh got it fixed, it appeared to be a very tiny solder splash near the demon... I want to thank all of you for helping me out! You are all great!
