can u explain that bridge setupagain
Here is the explanation of the Bridge Setup (Grounding Method) in simple steps.
The goal is to connect the Boot Pin to Ground (Minus).
1. The Setup (The "Bridge")
You need a wire to make a bridge between two points:
- Point A: The Boot Pin (Pin 57) on the chip.
- Point B: The Metal Case of the USB connector (This is Ground).
How to make the tool:
1. Take a piece of wire.
2. Tape one end to the silver metal shell of the USB plug. (Make sure it touches the metal tight).
3. The other end is your "Probe". Tape it to a thin sewing needle.
* *Why a needle? Because the wire is too fat and touches the wrong pins. The needle is sharp and precise.*
2. The Procedure
1. Unplug the USB cable from the computer.
2. Place the needle on the Target Pin (Pin 8 from the corner).
3. Hold it steady. Do not let it slide up to the "Clicky" pin.
4. Plug in the USB cable to the computer.
5. Wait 3 seconds.
6. Remove the needle.
3. The "Skip One" Trick (No Counting)
Since counting is hard, use the "Click" to find your way.
1. Touch the pin that makes the CLICK (Reset). You know where this is.
2. Look at that pin.
3. SKIP the very next pin below it (Pin 7).
4. TOUCH the next pin after that (Pin 8).

[CLICKY PIN] (Reset)
[SKIP THIS PIN]
[TARGET PIN] (Boot)
4. The "Soldering" Way (If your hands shake)
If you cannot hold the needle steady, you will keep hitting the Reset pin. The best way to fix this is to solder.
1. Get a very thin wire.
2. Solder it gently to the Target Pin.
* *It is okay if the solder touches the pin below it. Just make sure it does NOT touch the pin above it (The Clicky Pin).*
3. Twist the other end of the wire to the USB metal case.
4. Plug in USB -> It will be SILENT.
5. Click Start in Flash Magic.
6. When it starts flashing, cut the wire with scissors.
Summary:
You are bridging the 8th leg to the USB Metal Case.
If it clicks, you are too high. Move down exactly 2 legs.
