<brag mode on>

So I had a broken motherboard from a customer who tried to install a cheapmod on a 1.3 motherboard and used the MCPX lframe. They broke the trace and a couple surrounding traces, and the Xbox obviously didn't boot.

I had another nonworking motherboard staring me in the face with a good MCPX, so I figured, "why not?"

I don't have BGA equipment, but I removed both the good and bad MCPX with a SMD hot air nozzle, cleaned up and prepped the BGA points on the board and chip, spent a few minutes making sure everything was lined up, and heated the MCPX back up with the hot air nozzle.

It's hard to judge when the solder has reflowed when you can't see it under the chip. But I took a guess, after a couple dozen seconds of hot air, let it cool and tried booting the mobo with transplanted MCPX.

OMFG it booted! love.gif

I WISH I'd taken pictures throughout the process, but didn't think it would work. Maybe for my next transplant!

Hi my xbox is frag and it has never been modded. But someone told me that is was cause I had a bad mxpc or the dO was bad. How do I replace the mxpc. Need some help.

Thanks, you know when I looked back at my post, my own bullshit meter did go off a little bit. ohmy.gif

Anyway, I still don't trust this mobo 100%, so it's become my "loaner" Xbox...

WOW! Kudo's to you man. Thats cool. My friends Halo Limited Edition transparent green Xbox (PAL) doesn't boot at all. Lol I plugged in a PC's ATX power supply just to see what would happen and it didnt do anything exciting lol. I was at least hoping for a spark or something to know that it WAS alive before I KILLED it lol. Anyway What would be the problem with this box? It just DOES NOT TURN ON. It used to and after about an hour of gameplay it would turn off and wouldnt boot for like literally MONTHS and then onetime it booted up and then died about 30 minutes later and now doesn't work at all. Whats up with this piece of junk?

Congrats, i know its quite some task. Ive removed the MCPX / GPU / CPU from a couple of boards now that i scrapped for parts. I used the hot air SMD rework station i have, it wasn't too hard removing them but ive never tried to solder one back down, i can guess its a pretty damn hard thing to do, i'm still going to attempt a CPU upgrade some day, if i'll ever pull it off or not i'm not too sure, i would love to give it a go though biggrin.gif

Somethings currently wrong with my rework kit at the moment, the hot air is hot, but its not heating up to full temprature like it used to, it melts solder alright but it seems a little 'low on power'? i think theres more than one heater in the gun, i think probably one has failed or is on its way out, ive checked the filters and everything seems fine. huh.gif

Do you have a pic of the board after youve soldered it back down? i'd be interested in seeing a pic of the final job.

Cheers. beerchug.gif
