I have done rgh's before and i have rgh'd a falcon before, but i soldered in my nand cables and dumped the nand successfully :biggrin: I then continued to install the glitch chip(ACE v3) i soldered all the points very well i then plugged in console and the power brick went red so i then de-soldered everything and smoothed the points out and checked for bridges, splashes, etc i then also checked the prongs was making contact with the casing but nothing :/ Have also changed power brick but doesn't work

Console also has the RROD x'clamp fix

Hey there, I have the exact same problem now... also a Falcon, I could also successfully dump the nand and program the Ace, but after installing the Ace chip my power brick goes red as soon as I plug it in the console. My solder points look fine too, but I'll re-do them too soon.

Do you have any news or success by now? I'll report once I've re-done the Ace install.

Check for a short, if you short any of the power lines you will get red light on brick. Thats one of many possible causes.

Thanks C Chrushev ! :smile:
With power lines, you mean the 5V / 3.3V / 1.8V soldering points on the modchip / motherboard? Or all solder points could be affected?
Is there a good way to test it with a multimeter?

Shorting on the motherboard, could be through the chip or due to the chip if its a bad one, or bad solder. Best way to test is undo everything and see if it boots (when you undo make sure you clean up solder points, no shorting).

Great, thank you again for your fast reply! :smile:
I have another noob-question though: will it boot even after I've read the nand, created the ECC and wrote the ECC ?

Reading the nand then booting is no problem.
You’d have to rewrite the original nand to boot up without a glitch chip, however.

Hey H Harmonic , thanks!
So, rewriting the original nand means to use "write nand" with the original nanddump1.bin? The only info about that I could find was here: https://team-xecuter.com/forums/threads/67124-How-do-i-write-original-nand-back-to-xbox
Alternatively, could I just undo the soldering and plug in the power brick to see if the bricks' LED turns red? Since this happens right now, even without turning the console on.
Sadly I'm still not at home and cannot do it, but the next days I can give an update on my progress.

Yes, just rewrite the nand with any of your original nand dumps.

Aa for the second question, I’d advise doing it first as if the power brick is turning red when you haven’t powered up the console, the likelihood of being able to rewrite your nand is quite low; this is because the board will not be reviewing enough/if any power to certain parts of the motherboard.

Thank you H Harmonic for you help!
I finally found the problem and fixed it.

The problem was a short on the Ace chip, especially the 5V point. No clue if it was a manufacturing problem with the chip or I've damaged it somehow with the soldering iron.
Luckily, I have bought a 2nd Ace chip, and after soldering it in the Xbox, everything worked!

Thanks again for everybody who helped here! I've learned much on the journey of my first self-hacked xbox. :smile:

No worries, mate!
Glad to hear you found the cause of the problem, good to know it wasn’t a problem on your side. Any other questions, do not hesitate to shoot me a message.
