Sprint Samsung Epic 4G Rooted Before Launch

Tweet

We just learned that Sprint has high expectations for upcoming Samsung Epic 4G sales as it will open stores doors early tomorrow morning to sell the device, and now we have one more good news for those of you that prefer their Android device rooted.

That’s right, as soon as you get your Epic 4G tomorrow you’ll be able to root it, not that we would recommend such actions. Apparently the root method is very similar to the Galaxy S root, which explains why the Epic 4G was rooted before being available in stores.

The root method below has been apparently used on two Samsung Epic 4G smartphones so far, but make sure you follow the step-by-step guys below. A more streamlined root process will be available probably down the road, but in the mean time this will have to do:

Description: This is a temporary patch to guarantee permanent root. Once custom kernels are released with root incorporated, this patch won’t be required anymore.
For now, this patch will execute on every boot ensuring the root environment is correctly setup

Directions:
Please follow all directions exactly. Copy/paste the commands.

Commands for copying downloaded files to phone:
adb push c:\downloads\rageagainstthecage-arm5.bin /data/local/tmp/rageagainstthecage-arm5.bin
adb push c:\downloads\joeykrim-root.sh /sdcard/joeykrim-root.sh
adb push c:\downloads\jk-su /sdcard/jk-su
adb push c:\downloads\playlogo /sdcard/playlogo

Commands for temporary root Exploit:
adb shell
chmod 755 /data/local/tmp/rageagainstthecage-arm5.bin
cd /data/local/tmp
./rageagainstthecage-arm5.bin
exit

exit will exit out of the adb shell, and then type adb shell again. this time it should drop you to # instead of $.
if it goes back to $, run the exploit again,
cd /data/local/tmp
./rageagainstthecage-arm5.bin
and exit out of adb and then adb shell again to see if its # .
if it doesnt work the first time, repeat 4-5 times. it will work!

Commands for permanent root:
after you type adb shell and have # (because of the exploit just ran), type these commands:
adb shell
mount -t rfs -o remount,rw /dev/block/stl9 /system
cat /sdcard/joeykrim-root.sh > /system/bin/joeykrim-root.sh
cat /sdcard/jk-su > /system/bin/jk-su
mv /system/bin/playlogo /system/bin/playlogo-orig
cat /sdcard/playlogo > /system/bin/playlogo
chmod 755 /system/bin/playlogo
chmod 755 /system/bin/joeykrim-root.sh

please reboot and type adb shell and then type su, it should drop you to root by changing the prompt from $ to #.

if this process, doesnt work for you, please post back. as time goes on, we will clean it up and hopefully once we have a custom recovery, it’ll be easy for me to put this all into one update.zip.

personally confirmed – 2 epics rooted with this process

So, can you confirm this SDX developers root method above? Did it work out for you or are you waiting for something a little easier to follow?
