A few days ago, we showed you how to install Froyo Android 2.2 (JPC build) on a Samsung Galaxy S. A lot of users root Android phones to gain additional features and run apps that aren’t allowed to run normally. Rooting also allows you to install the One Click Lag Fix app that removes even the slightest lags you might encounter while using a Galaxy S, making it the fastest Android phone out there. It scores a staggering 2100-2300 points in Quadrant benchmark when running the official Android 2.1 build with LagFix installed. We showed you how to root Android 2.1 on Galaxy S in a previous post. In this post, you’ll learn how to root Android 2.2 on Galaxy S.
You’ll need to download Odin3 v1.30 and Root Kernel for JPH (zip file contains everything).
Follow these instructions then:
- Extract and copy update.zip (provided in download) to the root of internal sd-card of Galaxy S.
- Run Odin with auto reboot unchecked and loading the i9000_Kernel.tar as PDA.
- Put the phone into download mode (turn off and reboot holding the power button, volume down button and home button) and flash the i9000_Kernel.tar.
- Take out the battery and reinsert it. Reboot phone into recovery mode (turn off and reboot holding the power button, volume up button and home button) and flash the update.zip you put in the root folder of your sd card.
- Pull the battery again and reinsert it. Reboot into download mode again.
- Run Odin with auto reboot checked, load I9000XXJPH_KERNEL.tar as PDA and flash again.
- Your phone will be rooted when it boots up.
