If you don't want to wait until the official update is released in your region, then you will have to read the preparation info below and learn how to manually apply the new firmware upgrade.
StageFright vulnerability allows attackers to gain access to your phone using a malicious MMS video message. If you don't want to have data stolen from your device, then you should flash the new update as fast as possible.
Since these updates are released in stages, then you can always use this guide below and learn how to apply the update manually with Odin tool. Check the guidelines below before starting the updating process:
- use this post only with the Samsung Galaxy Note 4 N910C.
- check the model number of your phone under Settings> About Phone.
- make sure that the SM - N910C value is listed as model.
- you can flash the firmware even if you're not based in Poland, as long as the model number matches the version listed above.
- do not attempt to update any other different Galaxy Note 4 models with the files that you will find in this post.
- download the Samsung USB Drivers from here, then install them on your computer.
- these drivers are going to allow your smartphone to be detected by the PC.
- for the updating process you will use the ODIN application and it needs those USB drivers to be installed too.
- disable any antivirus apps from running on your PC.
- disable Samsung KIES too.
- these apps are going to block ODIN from flashing any new Android firmware updates on your phone.
- enable the USB Debugging option in your phone's Developer Options menu.
- if you can't find the Developer Options, then you should unhide it first.
- go to Settings> About Phone and tap 7 times on the Build Number section to become a developer.
- get back to Settings and find Developer Options, open it and then enable USB Debugging.
- if the Galaxy Note 4 is rooted, then the updating process will revoke any root access completely restoring your device to stock firmware.
- no data will be lost if your phone is only rooted, but running a previous stock Android build.
- any custom Recovery will be replaced with a stock Android Recovery Mode.
- if your phone runs on a custom ROM, then the updating process can be completed only after you apply a 'factory reset' process too.
- the 'factory reset' steps are listed at the end of this article.
- 'factory reset' process wipes clean the system partition without removing any data from internal / external storage.
- if you install the update over a custom ROM without applying the factory reset, then your Note 4 device won't boot in normal mode.
- if the Galaxy Note 4 N910C phone runs on 100% stock Android firmware, then the updating process will be completed easily without losing any data.
- this guide is for advanced users, we cannot be blamed in case you brick the phone nor in case you lose any data in the process.
- read the whole tutorial first and do not skip any steps.
- make sure that the phone's battery charge level is over 50%, it will prevent it from powering down during the first boot process of Android 6.0.1 OS.
Now that you know all of the above you can get to the interesting part of this post.

- power off the device.
- boot Recovery Mode.
- select 'wipe data/ factory reset'.
- confirm process.
