The D+/- pins are correct but missing any ESD protection, so are not exactly a replacement for the USB receptacle contacts. Refer schematics, V5301 and Z5300 - the D+/- pad shown here are the J5300/1 test points. Using these without the ESD protection from those components may cause damage to the chips that interface to the USB. Same applies for 5V VBUS: correct pad but a lot of missing protective gear: F5300 2A fuse N5300 reverse polarity (and OVP?) prot diode C5300 100nF feed-thru capacitor to filter spikes and RF C5301 27pF capacitor to further filter RF L5300 choke to filter ripple and spikes the pad itself seems isn't shown in schematics For fixing a broken USB receptacle there are definitely better ways than using those pads. I think it's been some thread here that had a photo of a fixed USB that used short wires to contact to Z5300 and F5300 inside shielding can next to receptacle. To fixate the receptacle component you can use 2-component glue if the mech support pads are also gone. ID pin you'll probably not really miss, as it's basically useless for a micro-B-USB-F - it's a OTG thing and N900 can't do OTG. H-E-N doesn't need ID The D+/- short for fastcharge is specified as a simple short. No need for any resistor. One last thing: Battery minus is NOT GND! Don't use it like that HTH, click thanks if it did jOERG
