Alternate Point To Db1f1
« on: February 18, 2010, 07:30:00 PM »

Ok so I completely underestimated the point, I did not realise how small and fragile it was until I had stripped that tiny little dab of solder off. I read about some people having luck scratching down a bit on the point with anything to uncover a little bit of copper, I attempted this and have had no such luck. I did scratch a decent amount off, is there any chance this will cause problems with the 360 functioning if I had scratched too deep?

Also after searching around for alternate points I did find a few namely FT1U2, people have said that is much easier than DB1F1. If possible I would prefer to solder it to the top of the board but I havn't seen anything about alternate points for DB1F1 on the top of the motherboard, so I assume there are none? How does FT1U2 compare in difficulty to DB1F1?

I really don't want to mess this second point up as I can't be arsed cutting trace and soldering to the PCB, does anyone have any tips or maybe a video walkthrough on how best to solder the point? I have heard something about flux but I've really never used this before, what is it and is it recommended that I buy and use some for this point?

Lastly if I do have to do FT1U2 as the alternate point, would it be recommended that I solder the diode directly to the point or would it be easier to solder a wire - diode - then another wire to the J2D2?

Thanks much in advance

Ok so I got my small 30 gauge wire, didn't use any flux like recommended but I think I got a pretty decent connection to FT1U2, so I hot glued the wire down about 1/4" away from the point just like stated. Now the thing is, I was going to thread the wire through to the top of the board, but i'm not sure which holes are going to be filled when I place the case back on.

I think it would be easier if I could keep everything to the bottom of the board, I found this diagram http://img191.imageshack.us/img191/5145/db...alternative.jpg which shows a connection just like J2D2 ( I think it is directly underneath J2D2 ), could I just solder everything up to that connection instead of to J2D2 on the top of the board? If this is not possible, could someone point out a hole which would not be used when the case is put back on so I can safely thread FT1U2 through that and to J2D2.
