How to Make a USB Jig for your Galaxy S2!

Step 1. Cut the micro USB connector off your micro USB cable.

Step 2. Start taking off the plastic on the side with heavy-duty scissors or knife until you get to the metal bones.

Just cut it all the way until you can access all FIVE pins.

Although every microUSB connector is different, mine had all the  pin   soldered except for pin 4 (which is shown by the arrow below), this  is   the pin that’s unused, so it was easy for me to identify.  You need  to   connect a resistor in between this pin 4 and pin 5.  Pin 5 is located    to the right of pin 4.

Below is what the pins look like for microUSB:

 
Step 3. You will need resistors, I am using 100K Ohm resistors I bought at Radio Shack.

Step 4. Since the pins are so darn small, it’s going to be rather  hard   to solder the resistors right onto it.  So I got 2 insulated wire    pieces and solder them onto the pin 4 and pin 5.

Step 5. Below shows my wires soldered securely onto pin 4 and pin 5.

Step 6. Since I don’t have a 300K Ohm resistor, I am simply going  to   put three 100K Ohm resistors in series and solder them, this is    actually pretty fun to do.

Step 7. Last step is simply soldering the resistor piece onto the  wires   and voila, USB Jig is done.  It took me about 15 minutes at most  and I   haven’t soldered for around 3 years so not too bad so long as it    works.  You can make it nicer by putting some hot glue over it then    putting it in a case but I like having bare circuits, I can always make    new ones if I break it.

Step 8. Below shows my ODIN download count over 400+ on my Epic 4G Touch Galaxy S2.  This is before using the USB Jig.

Step 9. I turn the phone off then insert my new USB Jig, hoping that I did it right the first time.

Step 10. After about 3 seconds, my Epic 4G Touch Galaxy S2 boots  up by   itself to download mode, my “custom binary download” count reset  to   zero and says “erasing download information succeeded”.    Congrats!

Step 11. I reboot the phone and find the i9100 boot splash gone!
