I’m trying to make my zephyr CB 4578 box RGH with no luck using this chip
And this is my story:
At start my console was 9199 dash.
I dump my NAND 3 times (hade one BB 0X1B5 all times)
Solder the chip use this diagram
Make .ecc file with 360 Multi Builder v0.93 and write to console.
Write FW (zephyr.xsvf) to chip from this file:
Solder the chip to xbox, turn it on and…. NOTHIG – only solid green light.
This is what I tried already:
1. Write ecc file again.
2. Re-Program chip again.
3. Check with AV \ HDMI cables
4. Check wiring (re-solder all points over 3 times)
5. Jumpering on x360glich:
a. Jumper R3 only
b. Jumper slim points (near C5) + R3
c. Jumper Slim points only
d. De-jumpering slim + R3 points
Because the chip don’t have led Every time I turned the console I tried to hear the sound of “ticking” of the chip \ cpu \ fans – NOTHIG
Please help?
