The official and stable CM 12.1 builds are now live for all the Galaxy Note 8 Wi-Fi tablets. You can check the instructions listed in this post in order to learn how to install one of these builds on your device.
The CM 12.1 Stable ROM is based on the AOSP Android 5.1.1 Lollipop releases and now you can test it on your Galaxy Note 8 device. If you want to learn more about this new custom ROM, then you can follow CyanogenMod’s blog posts here.
Check the guidelines below before starting the installation process of all these new CM 12.1 Android 5.1.1 files:
- use this guide only with the Wi-Fi Galaxy Note 8 tablet.
– the model of your device has to be N5110 and it can be verified under Settings> About Phone section.
– don’t try to use this guide for any other different Galaxy Note devices than the one listed in this post.
- your tablet has to be rooted and it should run a custom Recovery like CWM or TWRP.
– the installed custom Recovery has to be updated to its latest version, so that it will support the Android 5.1.1-based custom ROM installation.
- in the tutorial you will find two extra preparations steps: the NANDROID Backup and the Factory Reset ones.
– the NANDROID Backup creates a full restore point for your tablet, one that you can use in case your device doesn’t boot in normal mode.
– the factory reset process is going to remove the old ROM completely, as it wipes the system memory partition.
– the CM 12.1 Stable ROM is not compatible with any other different custom ROMs.
– factory resetting your device is not going to delete any files from the internal storage of your tablet.
- in case you want to save any data from installed apps or similar files you can try Helium app.
– for Contacts and People details you can use the Gmail account to sync such data, so that you will be able to retrieve it after the installation of CM 12.1 is done.
- this post if for advanced users, we cannot be blamed in case you brick your device nor in case you lose any important files.
- check the battery power of your device and make sure that it is over 50%, it will prevent the Note 8 tablet from powering off during the installation process.
- read the whole post and don’t skip any steps.
