Update Samsung Galaxy S2 to RootBOX ICS 4.0.4 custom ROM, LG Launcher and SGS3 Theme Included

RootBOX ICS ROM On Samsung Galaxy S2

RotoBOX ICS is another custom ROM release that has been created by bajee11, an XDA Recognized Contributor. This new ROM brings an SGS3 Theme for your Galaxy S2 device and multiple other changes to your device’s UI along several tweaks and improvements added to your device’s operating system. Make sure to read the entire tutorial and if you cannot install the new ROM, then I strongly recommend you to ask for help by posting in questions in our comments section.

The Samsung Galaxy S2, that you wish to update with RootBOX firmware, should be rooted and CWM Recovery has to be installed, because otherwise you won’t be able to flash the ROM and you will need to read the instructions listed in one of these posts here.

This new custom ROM is based on ICS 4.0.4 IMM76I by AOKP and it uses a standard Fluxi ICS Kernel. Within its features it packs a Nova Launcher and an LG UI 3.0 with 240 DPI and Samsung Galaxy S3 theme. Also, it packs a Sense 4 Task manager, Solid Explorer, Apollo Music Player, DSP Manager, Modified Toggle Icons, Multiple Waves Lockscreen, Memo app from LG, Inverted Messaging, Contacts and keyboard with black&blue templates and multiple other features and functions that you can discover by yourself after the installation is complete.

Before moving to the ‘how to flash RootBOX ICS custom ROM on Galaxy S2’ guide, you will have to read several guidelines and info that will help you prepare your device for the updating process. If you can’t understand or if you’re a beginner when it comes to work with CWM Recovery and other Android sub system tools, then you should ask a friend equipped with a bigger set of Android management skills. Here’s what you need to know and what to keep in mind before updating the ROM firmware:

  • Your Samsung Galaxy S2 should be rooted and CWM Recovery image installed. Without these two requirements met, you won’t be able to flash RootBOX ICS.
  • Before installing RootBOX ROM you will be asked to wipe all data stored on your phone, and this means that you need to move the important files on your Galaxy S2 internal or external sd card as these won’t be affected by the flashing process. Also, you can move the files on your computer and restore them after the update.
  • The applications currently installed on your phone should be also backed up using AppBak for Android tool.
  • Call Logs details and the SMS Text Messages can be backed up using the following corresponding Android applications: SMS backup & restore | Call Logs backup & restore.
  • Contacts and phone numbers can be synced with the Gmail account you’ve set for your Galaxy S2. This guide will help you sync the contacts with your Gmail.
  • APN Settings are usually saved even if you change the ROM firmware. But, if you want to be sure that you will be able to browse the internet after the RootBOX ICS installation, then you should use this guide here and learn how to backup and restore APN Settings info.
  • USB Debugging mode should be enabled and you should also make sure that the SGS2 battery power levels are over 70%.
  • If you’re coming from a different ROM then I strongly suggest you to create a full / NANDROID backup using CWM Recovery, ROM Manager or ROM toolbox lite utilities. The phone can then be restored to your current working ROM installation with one of these small Android apps.

That’s all the general instructions I had for you and now you can start to update your device with RootBOX ICS. Also, remember that you are changing the ROM of your phone with a custom one only at your own risk, as we won’t be made responsible if your device gets corrupted, damaged or you notice that some apps or files are missing after the update. Read the entire tutorial guide and do not attempt to skip any of the steps I’ve listed below.

How to update Galaxy S2 using RootBOX ICS Custom ROM:

  1. Download the ROM zip file package from here. Save the file on your PC without extracting the zip contents.
  2. Next, download the latest Gapps package from here.
  3. Now download the xxTweaker application from here. This one has to be flashed after both, custom ROM and Gapps, packages have been installed.
  4. Move all these three downloaded zips on your Galaxy S2 internal or external sdcard. Simply drop the files on the main sd card folder; do not create any new folders.
  5. Power OFF the device completely and make sure that it isn’t connected to your computer.
  6. Boot into CWM Recovery mode.
  7. When you’re in clockworkmod main recovery screen you need to select ‘wipe data/ factory reset’. Confirm.
  8. Next, select ‘wipe cache’ and confirm. After this you will have to select ‘wipe dalvik cache’, which can be found in ‘advanced’ menu. After you’ve completed the wiping cache action you need to move to the next step.
  9. Select ‘install zip from sdcard’ and then ‘choose zip from sdcard’ or ‘choose zip from internal sdcard’. Remember that the location depends on where you’ve placed the ROM zip file at step 4.
  10. Select the ROM zip for installation and confirm that you wish to apply it.
  11. Flash Gapps zip and after it the xxTweaker fluxi kernel zip file using the same actions as in step 9.
  12. After you have successfully installed all of the above, you will need to select ‘++go back++’ and after that select ‘reboot system now’.
  13. The Galaxy S2 device will now start its first boot with RootBOX ICS custom ROM and this process might take at least 10 minutes before completion. So, allow it to load all necessary files and when it is done you will see the Google setup wizard and then simply enter your account details, and that would be all.

Note that in case the First boot process takes way too long to complete, then you will have to remove the battery from your phone and after that re-insert it. Boot into recovery mode once again and repeat the entire tutorial. Also, make sure not to skip any of the steps I’ve listed above and perform the ‘wipe data / factory reset’ step as that’s one of the most important steps you have to take every time you decide to flash a new custom ROM.
