RGH STBY_CLK resistor burned trying to replace

[dat1000]

Hi all,

I've been given a falcon to try and fix after the original owner burned the hell out of the board trying to glitch it. After flashing it back to stock, taking off the glitcher and trying to repair the R4B24 resistor the box is booting with 3RL and 0022. Being totally honest my soldering isn't great, I can happily solder the CPU_PLL_BYPASS but this resistor is tiny to me. Seen as the board was pretty much going to get binned I had a go and these are the results


I know its messy but Its definitely not touching the other resistors but its only on the right pad where the R4B24 resistor was. Does the wire from the trace need to touch the left pad, and the resistor touch both left and right pads or should it be ok as it is? Im trying to fix a problem at a time and want to make sure that its definitely right. The xbox has a ton of other problems, it came without a nand for example so thats possibly whats causing the 0022 as well.

Any help would be greatly appreciated!

Thanks

Hmm withouth the clock resistor it shouldn't even boot. I also burned that resistor once but changed it from another xbox.

If you don't want to use smd components then you might want to connect a wire at both sides. Cause now you might rip the trace from the board.

For the rest if it boots then that resistor should be good.

It's most likely that your nand is incorrect. Do you have an original dump???

I think images of your other solder points are needed here. I would agree this has nothing to do with STBY_CLK.

Firstly thanks for the replies guys. Its definitely booting and doing a few resets (can hear the fan speed change) before it gives 3RL so hopefully its ok. I'll look at taking it off an popping a wire on with the resistor so its less likely to rip itself apart.

I've got whats supposed to be an original dump and a glitch image. The serial in the keyvault doesn't seem to match the board though so that might make it a little more difficult. Am I right in thinking that I can use a donor nand from my other falcon to boot into xell and grab the actual CPU key?

As for pics of the other soldering points, I'm at work at the minute but i'll post them when I get back. They're generally pretty neat but a few do have lightly burned bits like in the photo posted on the nand points. Nothing I could see was damaged though.

Thanks again for your help guys hopefully i'll be able to get it going again!

to find the real KV try to decrypt it with the cpu key of the console. If you don't have a valid backup KV, your only alternative is finding a banned one and glitch the console. 3ROL(0022) on stock dash is usually a KV problem (if hardware is intact). Does it goes RLOD right away or after some time?

[Xumpy]

Hmm, I don't really agree. I think that if your KV is incorrect you would get Christmas lights. (I'm not sure that this is for all the cases)

The 3RROD is more likely to be caused by the glitch chip. You do realize that you can not boot the stock dash with the glitch chip connected.

Unless off course when you remove the post wire. So try to disconnect that wire and try to boot stock again.

If afterwards you get Christmas lights then your KV is probably incorrect if you still receive a 3RROD then or your nand is corrupted (use a donor nand) or you still have a hardware error.

Hi all,

I flashed the nand image from my other falcon to it last night and got exactly the same thing, 0022 3RL after maybe 20 seconds. I am booting it with the glitch chip totally removed. I then tried to pop xell on it using the ecc file generated for my falcon, totally resoldered the glitch chip wiring and it didn't even try to glitch (no green light on glitch chip) only not giving 3RL (is this due to the fact the SMC just keeps resetting with the glitch xell on the nand?). I guessed I better look around the other solder points and found another dead resistor, the one directly below CPU_PLL_BYPASS, so I removed and replaced it with about as much skill as I did R4B24( i.e. not a lot) and tried to boot it again. This time the fans went crazy and the xbox popped and turned off, and it wont come back on now. I guess my crap skills finally gave it the push to give up and die.

Thanks for the help anyway guys, you pushed me in the right direction but I guess I'm just not skilled enough with the iron to be able to fix it properly. I've dropped it on the pile of RROD boxes and I pulled the glitch chip and popped it in my other falcon which I got to glitch immediately and is working perfect. Hopefully I'll get a little better over time and be able to go back and have another go at it.

hey dat have you got any solutioon for that? my jasper got the same problem, exactly.. it was glithing at first but then i lost the solder point of R4B24 when i was closing my xbox =/.. so when i went to fix it, I burned the trace and resistor R4B24..after that my xbox couldn't even turn on..so I did the bypass with a wire, but whitout a resistor.. then my jasper came to life but the matrix chip v2 wasn't glitchin, even the blue led wasn't flashing.. i got crazy then i switched back to original nand and damn... got 0022... help me plz! and by the way, which resistor i need to put on that?
