1. You need to enable USB debugging mode. This helps to connect your Android phone with the PC. See here: How to Enable USB Debugging.

2. Your phone battery should be 80-85% charged. If your phone goes off suddenly because of battery, during flashing ROMs or installing mods and updates — your phone might go dead permanently. See here: How to Check Battery Percentage.

3. Backup all your important data that you might need as soon as your flash a new ROM, or make a backup for just in case, you never know when anything might go wrong. See below on how to backup data:

Data can also be backed up using Samsung KIES for their devices, but if you backup data manually, you get more options what top choose from and it is very easy to move data across Android devices from different manufacturers, i.e moving Samsung Galaxy Note backup data to HTC One X.

4. Your phone should be factory unlocked. Additional instructions for locked Android devices will be added in the tutorial for unlocking devices.

    Does this have the pure ICS features that Samsung ICS doesn’t provide?
    1)Widget Tab in App Drawer?
    2) ICS lock screen?
    3)Lock Screen Widgets?And so many more…?

      No. This custom ROM is based on the official Samsung ICS with Touchwiz.

      • Lalit Mali

        Another doubt
        Is this custom ROM baked on official source code released by samsung or the ROMdump from the guy on XDA who got ICS accidentally from service centre?

      Have you tried using a third party keyboard from Play store? Swiftkey or something.

        • Lalit Mali

          Anything worked yet?
          Download swiftkey keyboard on pc and transfer it to ur phone via bluetooth. Then you probably won’t need to make any keyboard inputs.

          Any phone will do work for u. Any brand any OS.
