1) I tried to rebuild traces with conductive silver pen without much of a luck. The traces can be improved, but I could not figure out a way to solder new mini USB socket to them. Once I try soldering, the silver paste just evaporates.

2) However, it is possible to use plated pads that are to the left from the mini USB position. You can find which of the 4 pads corresponds to pins 1,2,3 and 5 (as I recall, the two pads closest to Mini usb are pins 1 and 5 which are +5V and ground and the other two are data pins).
I don’t know the meaning of pin 4. It does not seem connected to anything on this particualr phone

You can buy a mini USB on ebay for 5 bucks and then solder tiny wires in the correct order. It is quite difficult job, and I mixed up pins 2 and 4. After you solder wires make sure you don’t have shorts and your connections are good. Then use superglue to isolate wires from each other on a surface mounted mini USB end. Leave it overnight to dry.

3) As I said I mixed up wires and I realized it after I put superglue on. So, I decided not to try this tedious soldering again, but found a mini usb circuit braker from sparkfun electronics. It is awesome. It allows you to solder your wires in a minute. But the problem is that the PCB is too big to fit into the phone. However, it can be fixed. You need to cut the mini USB circuit braker along the socket using a hacksaw (or better use some power tool with a circular very fine metal hacksaw on it), just along the pads of the circuit. Then you need to file the PCB on the bottom to make it very thin. BE CAREFUL not to damage the traces. The PCB should be about 1 mm thick or slightly less. Then you can file the case of the blackberry in order for this board to be able to fit in between the casing and the metal cover that protects internal circuitry. After that, you will need to cut a larger hole in the left side cover of the phone in order for your socket to be reachable by the cord. And the phone will work again.

Thanks.

Examine the socket. In the middle you will find a plastic piece. On one side of the plastic there are exposed contact wires, the other side is empty. Insert a small flat screwdriver into the empty half and pry lightly. Almost immediately, the plastic piece will break at the root (deep inside) of the USB socket. Carefully remove the broken plastic.

Now you have access to the exposed contact wires. You can identify the bent one(s). Use tweezers to fix the shape of the bent wire(s). Takes patience, but easier than soldering off the entire USB port.

Once finished, get a good quality adhesive (I used epoxy) and glue the plastic piece back in. You may be laughing at this point but think again. Remember how little power it took to crack the middle piece. I can guarantee that if you use good quality adhesive, the new bond will be several times stronger than the original.

Again Thanks for those who are far geekier than I, i owe you a great deal of respect and perhaps a suggestion… im glad u have a tech like hobby, get laid, it helps being savvy an suave :P

thanks

Nice work, though.

Now that the phone doesn’t know if it is plugged into a mains charger or not it’ll never charge up from a dead battery state. These phones don’t charge from dead by USB, and they don’t charge at all using those 12V->5V “USB” car adapters (the 12V car plug with “USB” port in the end).

So don’t let the battery get into a state where the phone refuses to turn on, or you’ll be the proud owner of a shiny brick ;)
