its just fuse.. you can forget about it if you think that your charging supply will not do anything stupid.. its fuse, so the end on witch your should solder the wire are the same as another side of the same fuse, you what you can do is to solder your wire to a new location called N5300, but i dont know on witch side of N5300 you can.

and you than put your FUSE an wire itself, so thats how you can still have a fuse on your n900

i find 2 additional spots for +5V. just look at photos.


btw, i have n900 with broken USB port to.. so just planning to buy new port and solder everything by myself with shaking hands


and for everyone, im not suggesting using glues, cause if somehow it will broke up again, you will have a big headache to remove them..
