Galaxy S 3 (I9300) Build

This explains how to build Replicant for the Galaxy S 3 (I9300).


Before building, you must make sure that:


Do not build as root, always build as user.


All of the following build commands need to be run in the source tree root folder.

First, the toolchain needs to be built:


If you have executed any of the commands below and you want to run the toolchain build again, you will need to open a new shell.

Then, prepare the shell environment for the Replicant build:

. build/
lunch replicant_i9300-userdebug

Start the build:

parallel_tasks=$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc)
make -j$parallel_tasks bacon

The -jn argument is to indicate the number of parallel tasks during the build.
You can remove it from the command line to have only one task at a time. With fast hardware, best results will come with -j9, -j16 and -j32.

Finally, sign the resulting images:

./vendor/replicant/sign-build i9300

The first time you run the script, it will ask you a few questions that are needed to generate the necessary signing keys.

Output files

The produced files are located at:
  • built target images: out/dist/i9300/
  • built host tools: out/host/linux-x86/bin/
