Description of problem:
Was the console working before you started: Y

Do you get a green debug light appear on the RGH chip every 4-5 seconds: Y

How long is the light on for each time: 3 seconds

So i've started with my second key extraction on the corona and i have some problems.

The RGX keeps glitching but wont ever boot in Xell, i've tried every RGX file (A, B, C) and different wire lengts for CPU_RST and POST_OUT

On the post_out i have a 54cm Kynar wire (green wire in picture)

And on the CPU_RST a 10 CM wire

I've cleaned up my previous solderings and soldered it back. But thats not working either.

There are also no bridged to be found on the board.

I've flashed the Original nand back a few times to check if the xbox was still working and it does!

your soldering is woeful

the Ft3T10 point looks f**ked.

RGX isnt the best solution either, i had one and it never booted in any console i tried, and my soldering is perfect!

swap out the chip for a slim protov1/2 and clean up the soldering!!

your in real danger of lifting points, im surprised you havent damaged anything already.

practice on scrap PCB's before you try to solder on the xbox. you need practice!!

Heey gaz,

I've cleaned up the FT3T10 point and it looks much better now then on the picture.


I've also changd from the FT3T10 to the R4P4 and shortend the wire to 5cm. (CPU_RST)

It boots into xell after 6 blinks.

Luckily i dont RGH bot only use it to extract keys!

It works now luckily, thanks!

And next time i do this i'll get a new iron first.

The one i'm using is a bit crappy.

nice glad you got sorted!!

having a good iron is a must, especially for the smaller points
