Hey, 'great' incoming first post here...hope this is the right section!

Any who, I was able to cut the board and use a CK3 v2.x knock-off (bummer - didn't know before the purchase) probe successfully. I managed to extract the key with JungleFlasher, but I'm running through some issues repairing the PCB - typical, of course.

After using the conductive paste and letting it sit for a few hours I had forgot to test for continuity between points. I was greeted with a flashing middle green light on my 360 - upon taking it out I figured out the problem - the 'ground' pad (e.g. the pad that would've taken the resistor, etc. in my knock-off) had literally blown off. It left a crater where the pad should have been, I believe the pad blew because I used too much paste and crossed lines. Is there any hope/suggestions for repair? I'm willing to send the drive out if need be, although my father can take care of any difficult electrical work.

For what it's worth I extracted the key and haven't tried to reflash it yet - I was going to ensure it was completely updated before flashing to 1.9. The drive shouldn't be bricked by any means, I think.

Picture taken from their tutorial for reference -

Ground pad is what blew up/shorted out.

Pictures of my board (filled in hole with conductive paste - board no longer seems to want to explode, although it is getting hot. Previously (after the explosion) the board wasn't receiving any power.)

I'm assuming there's a tad too much paste on both repairs. Using a multimeter there's continuity between both repaired pads...which seems odd considering one is 3.3v and the other is ground. I didn't think to test the top pad with another pad on the same line.


summary : cut board, got key, repaired cuts, cuts weren't repaired correctly (?), pad blew off board (literally was a hole where the pad should be), board drive no longer wants to work with my amateur repairing - seems to be getting hot, though.

Thanks in advance, my apologies if I formatted the links wrong or wrote nonsense for 4 paragraphs.

I wish I known, actually. I ordered that probe about 2-3 weeks ago - before the newer easier one was available...at least openly available. I'm new to the Xbox scene - very familiar with the PS3/PC scene though.

Thanks for the link though, I honestly had no idea what to search!
For what it's worth (I saw my profile thing didn't update) It's a 93450C from August (2009?). Not sure on the board.

The Probe 3 has been around for a number of months now. You may have been better to post the question here before purchasing anything and we would have looked after you :)

It doesn't matter about the drive version - all phat 360 Lite-ons are technically the same drive regardless of the number (7/8/9 series drives as they're otherwise known).

Haha, I realize that now! My fault for jumping into something without too much research :p. I'll get back to you guys later tomorrow night if I run into any issues :p.

Hey guys,

Well, I got around to soldering a wire from the front to back, here are pictures. I'm assuming I did something wrong, since it's still not fixed :x.

Sorry for the meh quality - Droid definitely does.

Any who, when I plug the drive into my CK3 knock off tool, normally when I set it to 'ON' LEDs would consistently stay on...however, now, they flash for a second and go off. I didn't test to see if the board itself was actually receiving power though; I don't want to risk burning anything else :x. I'm assuming something is funky considering before the pad repair the tool's LEDs would stay on...in fact they stay on even if I don't have the tool plugged into the drive. Not too sure what to be testing with these repairs, either, though.

Sidenote; although this isn't related to the power issue, what's the best way to get that excess paste off past scraping? Ultimately I'd like the board to be as clean as it possibly can, but yeah. Scraping wasn't getting me too far :/.

In the meantime, I think I'm going to go through all 60 pages of pad 101 repair on a different forum :p. PCBs obviously aren't my strong point!

And sorry for ignoring the last post! That would help in the future if I don't get this board repaired, though :p.

Hey Buddy first you did a poor job on it that PCB cut won't be fix that easy, you need a unlocked PCB for around $82.00 bucks that will solve your problem... Next Time have someone do it for you:facepalm::crazy:

Haha, I wasn't aware I could just flash the key to a new drive...I may end up doing that if this drive is dead. I'd have to buy another 93450c drive, correct?

I'd hope Elpupy doesn't reply since it seems he has less of an idea as to what he's talking about than I do :p.

It does not matter which series the drive is you buy whether its a 74850c 83850c or 93450 they are all the same drive.they all become 0251 when you update to 13599 dash.if you buy a 7 series drive and flash 9 series firmware to it , it becomes a 9 series as hardware is exactly the same just different firmware.hope this helps you understand

Hm, got it!

Well, if my research doesn't go too swell on the pad repair I'll just purchase a new drive. Thanks for the help! Otherwise I just would've given up, haha.

all phat liteon are the same.its only firmware thats different.and as i said there is only one type of drive now and thats 0251.c4 does not have to write 4 different types of fw now for phat liteons ,he writes one and its 0251.


Its always best to use the same drive as you have originally. Theyre not that expensive to be honest. on ebay £25 including postage.
