PSFreedom for the N900 modified to work on Palm Pre!

**The Central Scrutinizer** · 09-04-2010,08:31 PM

Long Time Blake_Zero here on our site, has modified the PSFreedom which was originally for the N900 phones, to now work on the Palm Pre. -- Our many thanks here at PSX-SCENE for his wonderful efforts and helpful info below on how to get your Palm Pre to JailBreak your PS3 console. -- This just keeps getting better!

Forgot to mention that this 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:

Code:

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:

Code:

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

Code:

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):

Code:

. /usr/local/pre/setup-env

Extract and compile Pre Kernel

1. Extract the kernel:

Code:

tar xvzf linuxkernel-2.6.24.tgz

2. Extract palm modifications:

Code:

gunzip linux-2.6.24-patch.gz

3. Change to kernel directory:

Code:

cd linux-2.6.24

4. Apply patch:

Code:

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

5. Copy configuration for the Pre:

Code:

cp arch/arm/configs/omap_sirloin_3430_defconfig .config

6.Compile the kernel:

Code:

make

(this will take a while)

Compile modified PSFreedom source (if your using the zip file)

1. Extract the files:

Code:

tar xvzf PSFreedom-for-PalmPre.tar.gz

2. Change to folder:

Code:

cd  PSFreedom-for-PalmPre

3. Compile PSFreedom:

Code:

make

Compile modified PSFreedom source (from git)

1. Extract the files:

Code:

git clone http://github.com/blake-zero/PSFreedom

2. Change to folder:

Code:

cd PSFreedom

3. Compile PSFreedom:

Code:

make palmpre

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:

Code:

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.

Special Thanks to kakaroto for creating PSFreedom, I simply made some small modifications to make it compile for the Palm Pre since it runs linux and also use musb

Also thanks to garyOPA for helping me with my accounts problems

Removed the module for pixi since it is not working

Nice work black_zero, with so many new options popping up nowadays, it wont be very long before everyone will be able to hack there PS3'S. Keep it up buddy

**blake_zero** · 09-04-2010,08:43 PM

I was late for the teensy or other boards so why not use my Pre

**dirtyburger** · 09-04-2010,08:54 PM

Fab work buddy!

**Xeauron** · 09-04-2010,09:02 PM

Any chance of an MDA Compact III port?

Seriously though, amazing work!

**dirtyburger** · 09-04-2010,09:03 PM

lol im stuck, anyone care to lend a hand!

thanks in advance!

Hi, KaKaRoTo here!
Nice work, but could you please fork my repository on github and push your changes to it, then let send me a pull request ?
Having a .tar.gz is no way to work, I have tons of local modifications and new unpushed commits and I have no reference at 'when' you took a snapshot of the git repository, so I can't do a 'diff' to find the changes... so just use git, commit your changes (+ it allows you to have your name in the commit log), then push it to github on your forked repository.

Thanks!
Good job,

KaKaRoTo

**remainnameless** · 09-04-2010,09:24 PM

WOW!

Simply Incredible. Thank you so much for your hard work!

I have a question. I have a Microsoft Virtual Machine image of Fedora 10. I don't see why this wouldn't work with that build. Am I wrong?

I am really excited to see if this works. I'll let everyone know if it does!

Again, much thanks. If it works, I would be interested in donating a beer or two to you.

Here is a patch file with the differences while I learn to commit the changes with git

**mumphster** · 09-04-2010,09:50 PM

I think it would be perfectly fine if you gave us a version of it with backup manager support. I know id appreciate it!!

(Or PM me it if you want <3 )
