I have a N900 in a really good condition - looks like new. But the USB Port is broken away. I tried first to fixing for myself, but i cant solder more as the jack itself on the right and left side. I have no such equipment to solder the contact.
Can someone fixing it for me please? I`m comming from germany. Please contact me with my email.

Hey all to give you an update on http://talk.maemo.org/showpost.php?p...&postcount=235
they couldnt fix it
they reported the pads had been ripped off the mainboard and it was 'beyond economical repair' they did say they would refund me the fee they charged for fixing it which i thought was very reasonable of them (though i havent checked my bank yet to see if they actually have).
so i ended up buying a second hand one off ebay for £48 - also with a borken usb port, but it still does data (flashed it ok - seems fine at 900mhz oc@ideal - im gonna swap out the mainboard into my old housing cos this second hand one appears well used and a bit tatty.
when i get some time ill experiment with my old mainboard to see if i can coax life into it somehow.
cheers

Thanks for your reply. So i will ignore the id...
Her luck
As soldering such tiny parts with big tools seems very difficult i decided to try my skills on a defect n900 i bought a while ago for cheap. Because every solder pad was gone, i decided to use a big usb cable.
Its pinout:
1 VBUS Red +5 V
2 D− White Data −
3 D+ Green Data +
4 GND Black Ground
For soldering I used this pic as reference:
In the attachment you can see the result. Unfortunately it didnt worked first, i found out the fuse was blown too. I had nothing similar lurking around so i placed a diode in its place.
After plugging in the device started to charge, even both drives showed up, but were not accessible. This is likely due to the n900 itself is not showing the dialogue to select connection type.
I dont know whats causing this, hope someone has an idea of what to check next.. /:
Thanks

First, you remove the outer shield (it's just "clipped" in). Then, you need to carefully cut the base. Watch for small SMD thingies, they're extremely valuable to getting cut, if knife/scizzor/whatever slips off. I recommend either sharp, thin knife, or small cutter tool.

If I use a knife, should I try to pry it upwards away from the PCB, or will this rip the solder points (and possibly nearby SMD components) off as well?

I don't think you have high chances of desoldering base, no matter of what type of soldering iron/torch you use. At most, you will heat up whole ground plane to unhealthy levels.
Prying upwards is IMHO bad idea, too - you may take part of outer ground plane away with you. N900's PCB is 7 layer one - you have nice chances of ripping few ultra-thin tracks, too. But, I have never tried this method (and I'm not planning too), so practice may wary.
Now, the bright part - base of shields isn't titanium it's quite easy to cut off, and I was able to do it with plain kitchen knife, every time I needed.to do such fix. Now, of course, using special carving knife would make life easier, for sure.
Anyway, you just cut it (no ripping, no level'ing) with ease.
