Before starting the installation process you should read the preparation info below:
- Use this post only with the Samsung Galaxy J7 smartphone.
– Don’t try to flash the files you find in this post on any Android smartphones. - The Galaxy J7 that you are about to update needs to be rooted and running the latest TWRP custom Recovery build.
- In the tutorial you will also find two extra preparation steps: the Factory Reset and the NANDROID ROM Backup.
– Do not skip any of these steps.
– The NANDROID Backup is required and you need to apply it in order to set a restore point for your device.
– The Factory Reset wipes all the data that was previously installed by the old ROM, this will wipe only the system partition.
– Factory Reset doesn’t delete any files from the internal storage. - If you wish to save data from installed apps, then you can use the Titanium Backup.
– The Contacts info can be synced with your default GMail account. - Check the device’s battery charge level, it should be over 50%.
– That will prevent the Galaxy J7 from switching off during installation. - Do not skip any steps and make sure to read the whole guide before starting the CM 13 install process.
- if you need more help, then you should use the comments field at the end of the post.
