Samsung Galaxy Note 2 has received its first stable Android 4.4 custom ROM, an unofficial and experimental OmniROM build. Read this entire tutorial and make sure that you won’t skip any steps in the process.
The OmniROM is a new project that was launched only a month ago with Jelly Bean 4.3 set as default operating system. Now, an XDA member and developer called UtkarshGupta along with the OmniROM team has managed to release a working build for Galaxy Note 2.
This is an AOSP Android 4.4 custom ROM with some extra features. Before starting the updating process, take a look at the preparation guide below:
- Use this post only for the Samsung Galaxy Note 2 model number N7100.
- do not attempt to flash this custom ROM on any other Android device, as you will end up bricking it.
- The Galaxy Note 2 that you want to update right now has to be factory unlocked, rooted and running a custom recovery image like the CWM or TWRP.
- During the installation you will be forced to Factory Reset your device.
- the factory reset process deletes all contents from your phone’s system partition, removing installed apps, sms, call logs, Contacts etc.
- factory reset doesn’t remove data from internal storage.
- Backup data from installed apps using Helium app from Google Play Store here.
- Backup SMS, call logs info and APN Internet Settings using the following tools for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore. Root access is required for some of these apps.
- Sync People details and Contacts info with your default Gmail account.
- if you don’t know how to do it, then you need to know that you can find more info here.
- Enable USB Debugging from Developer Options menu.
- Read this entire post, don’t skip any steps.
- This is a guide for advanced users, do not attempt to flash any new custom ROMs in case you don’t know what you’re doing, as you will risk bricking the phone.
- Note that we cannot be held responsible in case you brick the device or lose any important files in the process.
- Check the phone’s battery power levels and make sure that it is over 50%, so that the device won’t switch off in the middle of the updating process.
- If you cannot complete the tutorial, then you should ask for more help in comments.
