Preparation
1. Note: The SlimBean 3.0 ROM and following instructions are for the international variant Galaxy S2 I9100G model and will not work on other devices. You can double check your phone's model number by going to Settings -> About Phone.
2. BACK UP YOUR DEVICE through a recommended custom recovery tool like TWRP or ClockworkMod (CWM).
3. Make sure that the correct USB drivers are installed for the phone on the computer (download Samsung Galaxy S2 I9100G USB drivers).
4. Make sure that USB Debugging mode is enabled on the phone by navigating to Settings -> Developer Options (if running on Android 4.0 or later) or Settings -> Applications -> Development (if running on Android 2.3 or earlier). If the phone is running on Android 4.2, follow these steps:
- Go to Settings -> About Phone
- Scroll to the bottom of the screen and select Build Number
- Tap phone's Build Number seven times to unlock or reveal the hidden Developer Options under Settings. Then select the checkbox to enable USB Debugging mode under Settings -> Developer Options.
5. The phone's battery should be at least 80 percent charged.

Directions
1. Download SlimBean v3.0 ROM and Google Apps for Galaxy S2 on the computer.
2. Connect and mount the phone's USB mass storage on the computer with the USB cable.
3. Copy the downloaded SlimBean ROM and Google Apps zip files to the root folder on the device's SD card.
4. Turn off the phone and disconnect its USB cable from the computer.
5. Boot the phone into Recovery Mode. You can do this by pressing and holding the Volume Up, Home and Power buttons together.
6. Once the phone goes into CWM Recovery, make a full data wipe. You can do this by clicking Wipe Data/Factory Reset (use Volume buttons to navigate and Power button to select while in Recovery Mode).
7. Perform Wipe Cache Partition and Wipe Dalvik Cache under advanced option. This will prevent boot loops or any other boot ROM errors.
8. Go back to the main Recovery screen and select Install Zip from SD card.
9. Select Choose Zip from SD card. Using the volume keys, navigate to the SlimBean v3.0 ROM file you copied earlier to the device's SD card. Select it by tapping the Power button. On the next screen, confirm the ROM installation and installation will start (also repeat this step to install Google Apps).
10. Once Google Apps and the ROM are installed, navigate to "+++++Go Back+++++" and hit Reboot System Now in the Recovery menu. The device will now reboot automatically. Note that the first boot might take around five minutes to finish.
