Replicant

== Build system ==

 * root your phone

 * Backup your current system!!!

 * Check out the Dream Android repository following that howto: [http://source.android.com/documentation/building-for-dream],but be carefull...DO NOT put the files extracted by extract-files.sh in the build system...it would put proprietary files in your build,that you can't even redistribute,but keep wifi firmware for pushing it later if you can stand proprietary firmwares(/system/etc/wifi/Fw1251r1c.bin )

Android use a custom Makefile based buildsystem

 * Add the patches that can be find here [http://groups.fsf.org/wiki/Freest_hardware_comparisons/replicant]

 * Add HAVE_HTC_AUDIO_DRIVER := true to BoardConfig.mk

 * Add this patch for sound:

The RIL (radio library) can be replaced with the Openmoko RIL.  Use the following patch to enable phone-unlock PIN entry (FIXME: add information on where to get OpenMoko RIL and how to add it to Android build):

Build process:

Let's say that our build directory is ~/replicant

 * Add that file:

{{{

TARGET_PRODUCT := htc_dream

}}}

 To ~/replicant/buildspec.mk 

 * Then type

{{{

 cd ~/replicant

 export ANDROID_JAVA_HOME=$JAVA_HOME

 make

}}}

 * The files to flash are in ~/replicant/out/target/product/dream,flash them and then clear the cache

 * boot and push the wifi firmware if you want it

== Status ==

 * web browser crashes

 * ril seem to work(I made some calls and received sms,but can't receive calls) 

 * sound on the application cpu(the baseband cpu has sound too) now works
