How to unbrick Samsung Galaxy Nexus, GT-I9250, GT-I9100G, GT-I9300 and S3 GT-I9300

HI Guys
In my travels I came across a great website which allows you to unbrick or get out of the dreaded black screen of death on your Samsung Nexus or Galaxy S3 phone. This will work for the following models.

GT-i9250, GT-I9100G, GT-I9300 and the S3 GT-i9300. So I thought I would share it with my website users to help them out if they have a broken their Samsung phone.

I will quote the comments

For galaxy S3 GT-i9300, please carefully read this:
* Euro/Asian models are based on 4 core Samsung Exynos 4412 CPU
* JTAG access in all i9300 phones is DISABLED (password protected)and password is not available (yet).
* Repair procedure for bricked phones is performed via SD card

I have also added the direct download links below.

Just execute *.bat file from this package.
Installing drivers first would be pretty smart idea too.

i9100G phones which have ID 0xFFFFFFFE, download this archive, unpack and run *.bat file from root folder:


For more details on what to do with the files check the link below.

At any rate the way to tell if you phone is totally broken is to first of all make sure you have enough battery.
To do this remove the back cover of your phone and reseat the battery so that you are sure the phone is getting power and that the battery has not just gone flat for because the contacts are not touching correctly. Then charge your phone and leaving it charging for a few hours.

If that doesn’t work, the next step is to try removing the sim card and storage cards remove the battery and leave them out for about 5 seconds. Replace only the battery and charge it again. If you still have no luck here but you are sure the battery is charging there is a way to test that its still alive.

If you are using Windows, Go to the start menu and right click Computer and open Device Manager, and plug your phone out of the USB port and plug it back in. If the device manager makes a noise or moves as if its installing a driver the chances are the device is still working.
Try putting your phone into Download mode by holding down Power, Home and the Volume down buttons. Hold these buttons down until you see the following screen.
