    Note:


When booting into Recovery or Download mode, it's okay/best to press power just a split second after Home+Up or Home+Down
After reinserting the battery I find it safest to be patient and wait for the blocky battery icon to appear and disappear.
When booting into Download mode, you have to let go of the buttons before the screen draws.
Otherwise the Down button is interpreted as Cancel

So, your Samsung Galaxy S3 won't boot into recovery mode?


You are on a Mac and can't get any help from all these Odin posts.


You've heard horror stories of bricking a device and see warning screens saying... "Do not turn off target"


Scary huh?

Well first of all, you have to just get used to that.
You are going to do a lot of scary rebooting and battery pulling.
Download ClockworkMod Recovery

Get the version for "Samsung Galaxy S3 (T-Mobile)" from here.
(cd ~/Downloads; curl -LO http://download2.clockworkmod.com/recoveries/recovery-clockwork-touch-6.0.3.0-d2tmo.img)

Install Heimdall

This is tricky because at the moment, the current "stable release" 1.3.2 (and all previous releases) do not support the Galaxy S3
So, you are going to have to build from source. Take a breath. You can do this.
Get the source

git clone https://github.com/Benjamin-Dobell/Heimdall.git
cd Heimdall

Read the README.txt

less OSX/README.txt

Ignore what it says about libusb (use homebrew not macports)

brew install libusb

Build and install...

cd libpit
./configure
make
cd ..

# This resolves the issue: https://github.com/Benjamin-Dobell/Heimdall/issues/99
export CC=/usr/bin/clang CXX=/usr/bin/clang++

cd heimdall
./configure
make
sudo make install
cd ..

# NOTICE: Don't be concerned when you see this...
## make[2]: Nothing to be done for `install-data-hook'.

cd OSX
sudo ./install-kext.sh
cd ..

Now you are ready to use Heimdall to save your recovery!

/usr/local/bin/heimdall flash --recovery ~Downloads/recovery-clockwork-touch-6.0.3.0-d2tmo.img --verbose --no-reboot

Pull the battery and the power cable (not scary anymore)

I chose to pass the --no-reboot option because we are not ready to boot the phone yet. However, this does mean that you have to hard power down the phone with that scary message on the screen.
Download a stable ROM

First of all, you may not have to do this step. I couldn't mount the External SD card after going through all the effort to locate and download the zips, but I found the original zip downloads in /sdcard/cmupdater/
I have been using CyanogenMod for quite some time.
(cd ~/Downloads; curl -LO http://get.cm/get/jenkins/12602/cm-10.0.0-d2tmo.zip)

You'll also want to get the Google Apps installer
(cd ~/Downloads; curl -LO http://download.clockworkmod.com/gapps/gapps-jb-20121212-signed.zip)
Put all your zip files onto a MicroSD card and put it in your phone.
Boot into Recovery with Up+Home+Power

Install your zip files from the external SD card. If it complains that you can't mount it, you may have to format the card via CWM.
