Here is a thread I made xda-developers.com where we all can borrow a USB jig which is of great use for most Galaxy Users.

If you are interested to join in and help others out, I would be happy enough to incorporate your name there.

What is USB Jig?

- USB jig is actually a micro-USB device which consist of soldering a micro USB plug, and resistors/resistor (as long as you get value of 301k, however, some claim it will still work even between 300k - 400k, not exactly 301k).

The USB jig (not the home made one) should look like this:

Where to get one?

There are actually 2 ways to obtain this tiny piece yet important device for most samsung android users. You can either purchase it from ebay or make it yourself!

- Actually it is selling very cheap at ebay (roughly around US$ 2.00) and worth to invest. However, in my opinion, it is a MUST for everyone (you are exclude if you are not into rooting and flashing your phone).

- I will not go into how to make a homemade USB jig. You can refer to the link below for reference.

What does USB Jig do?

In short, USB Jig has 3 functions:

- Get into download mode (main function)
If you soft brick your phone, you can force into download mode using USB jig and reflash new kernel or ROM. As far as i concern, there are few ways to force into download mode, however this is the most simple way to get into it. If USB jig doesn't work, i don't think other method will work either.

If your phone is hard brick, i don't think this will work.

- Remove the yellow triangle
Once you flash your s2 with insecure kernel, a yellow triangle with exclamation mark will appear at boot splash. USB jig can do the trick to remove it for you. (i know flashing S2 with original will remove the triangle as well, but i just wanna point out USB jig function.)

- Reset Odin counter/Reset custom binary counter
If you flash custom ROM into your s2, the binary counter will record it, even after you unroot your phone and set everything to its original, Samsung can still keep track by referring to binary counter. No worry, USB jig will clear the counter. However, some manage to get away with it and still get a warranty, but better to be safe than sorry.

Quote from zedomax:
"And also works on these Samsung phones too:
Samsung Nexus S, Captivate Samsung i9000 Galaxy S, Samsung Vibrant , Samsung Fascinate, Epic 4G, Samsung Omnia 7, Samsung S 4G, Samsung Infuse SGH-i997, Samsung Galaxy S Ace"

There are question about I9100G version. It should work as well, since the different between G and non-G version is the processor only. However, the new G version come with GB 2.3.6, which means new bootloader (Newly G set sold in Malaysia come with it)! No worry, it is being solved! Scroll down and read on.

How do you use USB jig? (courtesy to mrsaccess for remind me this part )

actually this part is quite straight forward. however, i will still try to provide step by step guide (i prefer to do/read it this way, easier to read and understand).

a) how to unbrick your phone
- Turn off your phone and pull out the battery for 2 seconds.
- Put the battery back in the device and don't turn it on.
- Plug the jig into the micro USB port on the phone.
- After about few seconds, your phone should boot up automatically and bring you straight into download mode.
- Unplug the jig.
- Connect your phone with USB cable to computer and then flash your phone via the program "odin".

b) how to remove the yellow triangle
- Turn off you phone.
- Plug in the jig.
- After about few seconds, your phone should boot up automatically and bring you straight into the download mode.
- Unplug the jig.
- Turn off your phone by long pressing the power button.
- Turn it on again and the annoying sign should be gone.

c) how to reset custom binary counter
- Turn off you phone.
- Plug in the jig.
- After about few seconds, your phone should boot up automatically and bring you straight into the download mode(you should be able to see your custom binary counter here). The below message should appear below the counter in green.
- Unplug the jig.
- Turn off your phone by long pressing the power button.
- If you wanna check the counter, turn your phone on again using the 3 button combo or by using the jig.


Is there any problem you ask?
YES! Samsung does indeed keep track of every hack and trick out there. They eventually realize a lot of people is using this dirty USB jig method to reset the custom binary counter/remove the yellow triangle, in order to get a warranty, as they should have void your warranty and charge you for repairs!

Eventually they implement new bootloader into GB ver 2.3.4 onward to prevent USB jig from resetting the custom binary counter/removing the yellow triangle (confirmed by some owners in this forum).

However, this is random as i read that an owner with GB ver 2.3.6 manage to flash the custom binary counter. I assume it depends on which bootloader version they put into your phone then.

However, you can still get into download mode! Which is the most important purpose of all! Phew!!!
