Read the guidelines below and you’ll learn how to successfully install the Maddoggin JB ROM on your smartphone at your first attempt. Here’s what you need to do before getting to the tutorial:
- The files in this post can be installed only on the LG / Google Nexus 4 model number E960. You shouldn’t attempt to flash this custom Android 4.2.1 ROM on any other Android smartphone.
- Your phone has to be on unlocked bootloader and rooted. Also, you will need to use a custom Recovery in order to flash the custom OS. Guides for all that can be found on our dedicated Nexus 4 page here.
- Use the custom Recovery mode to create a NANDROID backup of your current OS. This will be very helpful, as you will have a full restore point for your device in case something goes wrong and your phone cannot boot into normal mode after installing Maddoggin JB ROM.
- If you want, you can create backups of SMS, Call Logs and APN Internet Settings using the following tools for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore | AppBack for Android application. You will be asked for root access by some of these apps and you should grant it.
- To backup the Contacts phone numbers and details you will need to sync them with your Gmail account. Guide HERE for those of you who don’t know how to do it.
- Remember to charge the phone’s battery so that it won’t power off in the middle of the ROM installation process.
- This is a guide for advanced users and you should continue with the rest of this post’s instructions only if you know what you’re doing.
- Note that we cannot be held responsible in case your device gets bricked in the process. Also, you should move all your important data files to your PC, so that you’ll be covered in case something does go wrong.
- Note that the tutorial will ask you to wipe data, but it will delete only the System partition, the one that contains installed apps, SMS, Call logs etc.
