USB Jig for Samsung

tsacky

Anybody knows where can I buy a USB jig as I bricked My Galaxy S2 trying to install Jelley Bean.

Thanks in advance.

What happened to it exactly? Maybe you don't need a USB Jig..

I got disconnected while using Odin. Now my phone won't turn on. It just displays a picture of an exclamation mark between a mobile and a PC.

A USB jig is only used when your phone is not even booting up yet still has an intact bootloader. The USB jig forces the phone to boot up and allows flashing again.

Your phone is booting up, your bootloader is intact. You don't need a USB jig.

What version of Odin did you use? What Jelly Bean firmware (code number)? What S2 do you have, i9100 or i9100g? Did you make sure you flashed the one that works on your phone?

Odin 3.07
Firmware: I9100XWLS8_I9100XXLS8_I9100FOPLS3_HOME.tar
Samsung GT-I9100G

Ehh, you flashed the wrong firmware. You flashed an i9100 firmware over an i9100g S2. They have completely different hardware.

Download Odin 3.07 here
Download the latest 4.1.2 Official Jelly Bean Samsung Firmware from here

Extract both of them.

- Go into download mode on your phone by holding the Volume Down, Center and Power buttons together. If the phone turns on, let go of the power button while still holding the others.
- Connect it to your computer. (Make sure Samsung Kies isn't installed on that PC as it conflicts with Odin)
- If your PC doesn't recognize the device, download and install the Samsung drivers from here
- Now, on Odin the ID:COM section should be yellow and the “added” message should be there.
- Up next, click on “PDA” and select the update file (the .tar one). (DO NOT TOUCH/TICK/OR UNTICK ANYTHING AS THERE IS A RISK WHERE IT CAN PERMANENTLY CORRUPT YOUR DEVICE AND MAKE IT USELESS)
- Click on “start” and in the end you should see the “pass” message displayed (Do not remove it until you see "Pass")
- Unplug the USB cable as you are done
- Turn it off again by removing the battery
- Boot into recovery mode (press on Volume Up, Home and Power buttons).
- From there wipe the system
- You can make a wipe by selecting “wipe data factory reset” and “wipe cache partition”. (By using the Volume Up and Down buttons and using the center button to select)
- Then, choose “+++go back+++” and “reboot system now”.
- The first boot might take longer than usual; don’t panic there is nothing wrong with your S2

Cheers!

Let me emphasize some steps:

(Make sure Samsung Kies isn't installed on that PC as it conflicts with Odin)

As in, uninstall it if it is there! You have been warned!

- If your PC doesn't recognize the device, download and install the Samsung drivers from here

If I may suggest an alternate link for the drivers from Softpedia...

Do NOT wipe ANYTHING ELSE!

Good luck.

I lost my n7100's IMEI once after wiping everything from the advanced menu.

If you have a Galaxy Note, or an S2 with the insane NAND chip, wiping emmc on ICS firmware could brick your phone to the point where even a Riffbox would hang while trying to fix it. Been there.

Now Samsung's Jelly Bean firmware are probably brick-free (very very high probability). Custom kernels had this issue taken care of before Samsung (since the ICS firmwares), as they had disabled the MMC_CAP_ERASE command which causes the bricking due to corruption in the EMMC's microcontroller's firmware.

Backing up the EFS partition is a good idea to avoid loss of the IMEI.

I wiped through clockworkmod. I was careless not backing up my EFS. Hopefully I learned my lesson.

The problem is I can't get to download mode. Here's what I get when I try to turn my phone on.

That's the same as download mode.
