The AT&T Galaxy S SkyRocket got a leaked new firmware, the Android 4.0 ICS UCLF5, and if you used this guide here to update it and you are an Android enthusiast that wants to root and install ClockworkMod Recovery, then you are in the right place and you should use the instructions listed in this article. First you will need to install CWM recovery and only afterwards you will be able to root the device.
The Android 4.0 ICS UCLF5 update was leaked and it isn’t an official release by Samsung, but you still need to root it. However, first thing that you need to do is to install a custom recovery image, the ClockworkMod Recovery. This installation will then need to be followed by the root process and only after that you will be able to install new custom ROMs for your device.
CWM Recovery will allow you to flash roots and custom ROMs and it is a very simple application that should be easy to handle by users that aren’t too advanced when it comes to Android devices. However, if you’re a beginner then you should probably ask on of your more Android skilled friend to help you complete this tutorial. Before we can begin the installation of ClockworkMod recovery, you will need to read the preparation guide and learn how to properly configure your Galaxy S2 SkyRocket and computer for the tutorial. Here’s what you need to know:
- apply the CWM Recovery image only on AT&T Samsung Galaxy S2 SkyRocket, model number I727. It will work only with this smartphone and you shouldn’t try to install it on any other Android device.
- Enable USB debugging option on your computer.
- Install the Samsung USB drivers for your smartphone.
- Install the UCLF4 Firmware of Android 4.0 ICS from here. If your device is already on this firmware then you should skip this step.
- Make sure that your phone’s battery is charged so that the SGS2 SkyRocket won’t power OFF while you’re in the middle of the installation process.
- Create backups of all your important files by moving them to your device’s internal sdcard. This step is optional and you should only apply it only if you’re afraid that the installation of CWM Recovery might damage some files stored on your phone’s memory.
- Also, you can backup installed apps, APN Settings, Call Logs info and SMS text messages using these Android programs: AppBAK for Android apps backups | SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore.
- Phone Contacts app can be synced with the Gmail account assigned to your phone. If you don’t know how to do it, use this tutorial here.
- In case something goes wrong and your device loses data or something else goes wrong, then you shouldn’t blame neither the developers of this custom recovery image nor us, because you are installing these files at your own risk.
These are all the steps you had to take before moving to the tutorial guide and that’s why now you are free to continue with the rest of the instructions needed in order to successfully install CWM Recovery using ODIN app. Remember that you will need an Windows computer and make sure not to skip any steps because that might result in you being forced to repeat the entire tutorial once again.
