So I was replacing the two external antenna/test points on my SGH-T999 and did not have my air temp correct which caused me to remove the solder pads along with the connector . If you look at the linked drawing on pg 4, the offset pad attaches to a via that connects it to the other side of the board. I need to find that point for both the connectors. So does anyone know where to get a copy of the schematics AND the pcb assembly dwg? Or does anyone already know where this point is? I'd be greatly appreciated.
Thanks!

He guys new to the forum, have a question for some help, I'm going to add an external USB port, because that part of my mother board is shot from some previous shotty solder work from someone, anyways, I'm trying to figure out where to solder the 5 wires, the pads from the old port are crap, trying to find somewhere else to solder wires, any help would be appreciated.
Hi i replace the screen of my i747 and when i pull out the antenna from the connector, the whole connector has removed!!! :crying:
theres is any way to fix it? or something???
Hi can someone identify what kind of connector the antenna uses?
It broke off with the cable need to replace a new one.
If you can give exact model, it would be much appreciated.

I bought an I747 and need to replace the USB jack. I bought a replacement on eBay and the jack has about 11 pins on the back that solder into the circuit board. There are 6 pins reasonably spaced that appear to be the USB ccircuits. On the outer edges are groups of pins very close together, one side has 2 pins the other has 3. It is very difficult to not bridge these pins with solder. I'm wondering if they serve an individual purpose or can they be soldered as a group? I am getting the USB not recognized error also. I have managed to solder then individually as far as I can tell. Anybody know what those putter pins do?
Hey guys,
I recently replaced the usb port on my LG G3, and while re-flowing the port i knocked off one of the resistor banks and re-flowed the IC directly below the usb port.
has anybody got a high res image of that area of the board so that I can ascertain if I am missing any of the components?
i think i am missing one of the 0102 resistors from the back.
Cheers .
found the schematic.

discovered that the flux that i used to de-solder the usb connector and gummed up the springs contacts for the speaker , so i dropped the board in some alcohol to remove what i could and added a bit of solder to the speaker terminals to give it a bit of height.
works like a charm now.. i can stop looking for a new phone.
