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!

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.

impressive!

Damn I wish you took pics!! Dang it must have been a time cousming task... How long did it take???

Cheers!

You sure it's from the MXPC or dO?? Since it's never been modded ... Chances are it could be the Harddrive croakin?? you hearin any click click noises??

Cheers!

thats not a bad effort at all, well done. try and replace the CPU next time jokes man

respect man. respect.

You can modify a ball kit for it.

Props man, props. (nearly anyone else I'd call bullshit).

-nB

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

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

wats a hot air nozzle? can i heat it enough with like a blow drier? or any other house hold object?

Ya but you need gasoline and ice cubes.


...Anyways, nice job perplexer, I don't even like dicking with lframe, I can't believe you replaced the mcpx. Cheers

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

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.

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.

mad props to you!

I'd buy or borrow one of those "thermometer guns" and point it at the tip, see what temperature is registering.


Doesn't look any different than a stock board, aside from a little flux residue around the edges which I've cleaned up with flux remover and a q-tip. You wouldn't know it's been replaced.

nice

Good idea, i think i might see if i can borrow one from someone, i'm not 100% sure whats wrong with it at the moment, it went like it 2 days ago and is still the same, i think one of the heater elements is down or on its way out, it shouldn't be too bigger deal to sort out.

It sounds like you did a nice job on replacing the MCPX, one day i'm going to have to give this stuff ago, ive always wanted to tackle a CPU replacement, i think i might have a chance, but i suppose all i can do is give it a go, the worst i can do is ruin a board and waste time, but i suppose its all good experience

I got to admit though, you got some pretty good tallent

is there anyting that i can use that will be cheaper than just buying a new mobo?

damn.. nice work perplexer...


... looks into closet with burned out mcpx mobo inside...

Damn! Props on that one Like NetworkBoy said, anyone else I would have called bullshit but you are definitely a soldering god!

Is there anyway to do this with the extra ram spaces? Cos I got a dead MOBO in the closet and wanna put the ram on my working mobo

Wow, that's amazing perplexer, barely unthinkable !!!! But how did you get shure it was the mpcx and not something else?? Did the board was FRAOing?? What were the symptoms??
