Video: PSFreedom PS3 Exploit Modified to Work on Palm Pre!

141w ago - Before the weekend we saw a Nokia N900 port of the PSGroove open-source PS JailBreak PS3 exploit, and now it has been ported to Palm Pre by blake_zero over at PSX-Scene.com (linked above).

Download: PSFreedom for Palm Pre / PSFreedom Module for Palm Pre

Instructions are for working on a linux box running Fedora 13:

Here is a modified version of PSFreedom for the N900 working on my Palm Pre. This version does not support Backup Manager. If Mods allow it I will post the compile module with and without backup manager support.

What you need:

1. The kernel package for the Palm Pre (linuxkernel-2.6.24.tgz) and palm patches (linuxkernel-2.6.24-patch(pre).gz) that you can find on Open Source Packages.
2. ARM toolchain for your the platform I use IA32 Linux toolchain, 2009q1 release
3. Compiled psfeedom module from the modified PSFreedom source
4. Root access to your Palm Pre, it could be by ssh or Terminal app on phone

Setting the ARM toolchain

1. Extract the file:

tar xjvf arm-2009q1-203-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2

2. Move the extracted folder where you like it to be:

mv arm-2009q1 /usr/local/arm

3. Set some environment variables so cross-compilation works. Create a new file named setup-env and paste this

export PRETOOL_DIR="/usr/local/arm"
(echo "$PATH" | grep -q "${PRETOOL_DIR}") || export PATH="${PRETOOL_DIR}/bin:${PATH}"
export STRIP="arm-none-linux-gnueabi-strip"
export LD="arm-none-linux-gnueabi-ld"
export CC="arm-none-linux-gnueabi-gcc -march=armv4t -mtune=arm920t"
export CPPFLAGS="-isystem${PRETOOL_DIR}/arm/arm-none-linux-gnueabi/include"
export RANLIB="arm-none-linux-gnueabi-ranlib"
export CXX="arm-none-linux-gnueabi-g++ -march=armv4t -mtune=arm920t"
export OBJCOPY="arm-none-linux-gnueabi-objcopy"
export PKG_CONFIG_PATH="${PRETOOL_DIR}/usr/local/lib/pkgconfig"
export PKG_CONFIG_SYSROOT_DIR="${PRETOOL_DIR}/arm/arm-none-linux-gnueabi"
#export LDFLAGS="-L${PRETOOL_DIR}/usr/local/lib -Wl,-rpath-link,${PRETOOL_DIR}/arm/arm-none-linux-gnueabi/lib -Wl,-O1"
export CCLD="arm-none-linux-gnueabi-gcc -march=armv4t -mtune=arm920t"
export MAKE="make"
export CFLAGS="-isystem${PRETOOL_DIR}/usr/local/include -fexpensive-optimizations -fomit-frame-pointer -frename-registers -Os"
export CXXFLAGS="-isystem${PRETOOL_DIR}/arm/arm-none-linux-gnueabi/include -fexpensive-optimizations -fomit-frame-pointer -frename-registers -Os -fpermissive -fvisibility-inlines-hidden"
export F77="arm-none-linux-gnueabi-g77 -march=armv4t -mtune=arm920t"
export AS="arm-none-linux-gnueabi-as"
export AR="arm-none-linux-gnueabi-ar"
export CPP="arm-none-linux-gnueabi-gcc -E"
export OBJDUMP="arm-none-linux-gnueabi-objdump"
export CONFIG_SITE="${PRETOOL_DIR}/arm/site-config"

you need to set PRETOOL_DIR to where you move the extracted folder. Finally Source the variables (use the path where you saved setup-env):

. /usr/local/pre/setup-env

Extract and compile Pre Kernel

1. Extract the kernel:

tar xvzf linuxkernel-2.6.24.tgz

2. Extract palm modifications:

gunzip linux-2.6.24-patch.gz

3. Change to kernel directory:

cd linux-2.6.24

4. Apply patch:

patch -p1 < ../linux-2.6.24-patch

5. Copy configuration for the Pre:

cp arch/arm/configs/omap_sirloin_3430_defconfig .config

6.Compile the kernel:

make

(this will take a while)

Compile modified PSFreedom source

1. Extract the files:

tar xvzf PSFreedom-for-PalmPre.tar.gz

2. Change to folder:

cd PSFreedom-for-PalmPre

3. Compile PSFreedom:

make

Copy and install psfreedom.ko module to Palm Pre

1. Connect your Palm pre to PC on drive mode and copy psfreedom.ko to it
2. ssh to your pre (or open terminal app) and insmod the module:

insmod /media/internal/psfreedom.ko

Now you should be ready to go

1. Turn completely off your PS3 with firmware 3.41
2. Connect your Palm Pre to the usb of PS3
3. Turn on your PS3 followed by rapidly pressing eject
4. Wait for your PS3 to reboot
5. Enjoy

After using your PalmPre for this exploit you should make a complete device restart to restore usb functions.
