I have a i9003 that have removed the USB port and the tracks are broken.
There would be a way to solder a new connector knowing where to solder the wires would have to load and have USB connectivity?
Best regards.

I have just bought an imate 9502 with a broken charger port (usb plug) inside someone has tried to fix it by linking the pins from the usb port to the pcb but have failed so bad that they have completely f*ct where the pins soilder to the pcb, i was hoping someone with a 9502 would be willing enough to open theres and take some macro photos of the usb port so that i can attempt to trace back where the tracks go and fix my phone.
Any help would be great thx.
P.s in the meantime does aybody know where i can get an external battery charger?
I ended up fixing it by removing the old usb plug and replacing it with a new one and than tracing back the power wires on the pcb than i bit of trial nd error but in the end found them, soildered some tiny copper wires back to the new plug and it now charges perfect
Only downside is that the usb still doesen't work so no sync with the pc at all
which usb plug did you need and where did you get it from?
it would help alot as i am also thinking of doing this to mine
Alright; so the connector where you plug in the ribbon cable for the mic, the white fastener that
acts like a breaker decided to fly off so my mic doesnt work. If I put solder in the area where the
fastener was; will that make the connection work and therego make my mic work again? I really
don't want to buy a new mobo, I just bought a new lcd and digitizer...... response asap would be
greatly appreciated!

Not unless you can solder the individual cores of the ribbon cable back onto the right place on the motherboard, no.
Hi guys. This is gonna sound awkward. I'm having issues in my personal life and I was talking on whatsapp with brother when I got angry and threw my nexus. the screen is broken like colors and stuff and lines so I tries to turn the phone off by touching where the power off button appears on screen butI couldn't.
since I was angry I removed the back cover and cut the golden wire at the bottom point where it turn. I've tried turning it on by holding the cut ends but no luck. tried charger too but nope. All I wanna do is get into recovery somehow (TWRP) and dump my internal storage.
Thank you.
After some thought about your description.... I wonder if you have actually cut the main ribbon cable from the microphone/speakers/USB assembly this is the one that runs down the side of your phone. your best bet will be to purchase another cable assembly.. since you are dealing with a multi conductor ribbon cable.
I really doubt that you will be able to repair and re-connect the cable without some pretty highly skilled soldering ability.
The battery cable is very short and comes directly out of the battery itself... it is not likely that you actually cut it but did cut the main circuit cable. Too Bad, but this will be a real problem for a repair.
no joy... but you might want to investigate a reputable repair shop.

Thanks so much for replying. Yes indeed I cut the ribbon cable. I'm in no position of buying a new one. I guess I'm gonna take it to someone with high soldering skill. Before that I'm gonna try tape too

Question: if this ribbon isn't battery wire then why the phone doesn't start
main connection cable ( do NOT cut)

That ribbon cable is the one that interconnects the working boards in your phone, Microphone, Speakers, buttons. Unlike the battery cable you probably won't be able to fix it... it is pretty much a replacement only part.
this part is called -- LG Nexus 5 D820 D821 Charging Port Flex Cable Dock Connector USB Port With Mic Microphone Flex Cable Repair Part (amazon.com)
you will have to source a supplier close to you... but the good news is that it is relatively inexpensive... Ebay has it listed for $10USD or so.
not trying to be the bearer of bad tidings... but I've spent 20 odd years repairing computers and associated devices. It is always best if you don't cut ribbon cables.
Hello,
The USB port of my Samsung Galaxy S3 is broken. I bought a new one and tried to do the repair. By loosening the USB port (the broken one), the connectors of the circuit board have taken off and therefore I cannot weld the new USB port on the motherboard.
I would need the complete pinout of the USB port (11 pins) as well as a diagram of the motherboard to know where I can solder bridging cables from the USB port pins to specific locations on the motherboard (which is done normally by the brass paths on the printed circuit).
Thank you

Greetings and welcome to assist. Unfortunately this isn't the sort of thing we do at assist and would have no idea where to get the diagrams. It is probably best to contact a service centre for advice

Hi all,
I am trying to mod my old tf300t and keyboard dock into a dex dock for my note 9. Im not worried about the tablet portion as i can get a lcd controller for the panel. However ive been soldering and desoldering for the last 3 days. I am trying to leverage the docks kb controller and add a usb connection or modify the dock port into a usb.
I have looked at the various pinouts but cannot get the keyboard working.
I dont care about audio or sd card or the extra usb port.
Any help or pointers would be great.
Here is a mockup of the pinouts i have soldered based on the pinouts i found
Ive been trying to test it on an old s7edge incase i wire something wrong. It detects a regular keyboard but when i try this nothing...if i use the wall charger i see that the dock is charging but still nothing at the dock connector. Ive been trying with a usb 2.0 cable. Connected to the d+ d- vcc ( all 3) and multiple grounds and i pinned the sense pin to ground as well.
I have also tried to open the charge cable and solder the usb to the data pins on that both with and without ground. And use a 5v plug and the original asus plug.
The dock port is basically garbage at this point so if i plan to use that i need to use the 2 20 wire connectors and map the individual wires .
I have managed to get the s7edge to detect that something is connected. However i then resoldered the pins to try more as it wasnt working. So i need to go back to the beginning to try again. I believe my issue was due to the otg aspect of the usb. Im using an adapter for the phone but i also tried to wire the connector the same way. Ill take some pictures of it later if i can get it working
So not sure if anyone is following this thread but i have made progress.
I have totally butchered the original 40 pin connector and now am tapping into the 40 individual wires that connect the main board to the connector pcb. I can get my s7edge to detect that the usb connector is attached but it keeps telling me that a high power usb device is attached and that it needs an external power source.... so today i busted out the multimeter and i believe i connected one of the usb host vcc connections to the other vcc connections so i separated this. I also believe that the s7edge has some usbotg voltage issues so im going to test it with an old macbook pro with windows to see what it picks it up as. When i get some more time i will try to trace the other wires there might be something else needed
Maybe
Nice job, I'm not particularly knowlegdable in electronics but I remember there is a battery portion in the dock? Maybe it causes some error during otg?
