How to Install InsertCoin ROM on Galaxy S3
- This procedure will wipe all your apps, data and settings (but it will NOT touch your SD cards, so don’t worry about those). Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
NOTE: Don’t forget to at least note down your network’s APN settings, which are required to make mobile data work. Go into Settings » More » Mobile Networks, click on the APN that is in use, then note down the setting for each field. While APN settings should be automatically restored from network, you can enter them manually if needed to make mobile data work. You can also find your APN details → here.
- Make sure you have ClockworkMod recovery installed. If not, use this guide to install it.
- Download the ROM from this link (the latest version of the ROM can be downloaded from the source page).
- Copy the ROM’s file to the internal storage (do not extract it).
- Now, boot into ClockworkMod recovery. To do that, turn off your phone. Then, hold down Volume Up, Home and then the Power buttons together until the screen turns on, then let them go. The phone will boot into ClockworkMod recovery in a few seconds.
In recovery, use the volume buttons to scroll up/down and the home button to select an option.
- Perform a full backup of your existing ROM, so that you can always restore it from recovery if something does not work out with this ROM. To perform a backup, tap on Backup, then slide the blue circle button at the bottom to the right to start backing up your current ROM. Go back to main recovery menu after backup is complete.
- Select wipe data/factory reset, then select Yes on next screen to confirm. Wait a while till the data wipe is complete.
