Open China has released the official Android 6.0.1 Marshmallow OTA Update for all their Galaxy Note 4 users. Check the info in this article in order to learn how to successfully flash the new firmware on your device.

If you own the Open China model of Galaxy Note 4 and you don't want to wait for the update to arrive in your region, then you can choose to flash the Marshmallow firmware manually using the Odin app. These update are usually rolling out in stages, but there are also some users that have modified the installed ROM and now they are looking to restore their Note 4 to stock Marshmallow OS, which is why they can use the same Odin app, too, in order to upgrade their phones.

Check these guidelines before starting the installation process:

  • use this post only for the Open China Samsung Galaxy Note 4 models.
    - check the model number of your device under Settings> About Phone section.
    - the model number of your phone to be the SM - N9100 firmware.
  • don't try to update any other devices with the files that you will find in this post.
  • download the Samsung usb drivers from here, then install them on your PC.
  • for the installation of Android 6.0.1 you will have to use the Odin app.
    - Odin requires your PC to run the latest usb driver and for the USB Debugging to be enabled from your phone's Developer Options.
    - if you can't find Developer Options you need to unhide it.
    - go to Settings> About Phone, tap seven times on Build Number.
    - return to Settings, find Developer Options and then find USB Debugging to enable it, too.
  • if your phone is rooted, but the firmware is still stock, then no data will be lost except for the root access.
    - also, any custom Recovery you might have installed is going to be replaced by a Stock Recovery image.
  • if your phone runs a custom ROM you can flash the new official firmware update, but you will have to factory reset the system partition.
    - the 'factory reset' process wipes clean the system partition, but it won't delete any data from internal storage of your device.
    - the 'factory reset' steps are listed at the end of this post.
    - factory resetting the phone means that the old custom ROM will be wiped and you will see the device booting in normal mode.
  • if your phone is running 100% stock Android firmware you can continue straight to the next part of this post, as no data will be lost in the process.
  • read the whole post and do not skip any steps.
  • this is a guide that you should use only if you are an advanced user, do not blame us in case you end up bricking your phone nor in case you end up losing any important data files.
  • check the battery charge level of your phone, make sure that there is at least 50% charge left before the phone powers off completely.

If you don't want to manually flash the update and your device is still running 100% stock Android firmware, then you can wait until Samsung pushes the new update over-the-air in your region. Also, you can manually search for new files by going to Settings> About Phone and using the System Update section.
