Together with the release of Android 6.0.1 update for Galaxy Note 4, Sprint also released an official software update for Galaxy Note5 (SM-N920P). Just like the updates for the other devices, it’s brought Marshmallow main features like Now on Tap, Doze for better battery usage and improved per app permissions. In addition to the core OS, the update also delivers the renewed Samsung’s own user interface, the TouchWiz UI with an enhanced functionality. Furthermore, some features are also inserted like Quick connect, vibration pattern, advanced power saving modes and much more.
You can immediately get Marshmallow updates via OTA, you can also upgrade it via Odin flash tool when the stock N920PVPU2BPC3 firmware is available. To apply the update files via OTA, your phone must be in a state of stock and unrooted. If your Sprint Galaxy Note5 still having root access or you have made some other changes such as replacing the recovery with TWRP, then you have to restore it back to stock.
After updating, regain root on Sprint Galaxy Note 5 running Marshmallow is not too complicated, thanks to Sprint to the make the bootloader unlockable. There are several ways that we can apply to obtain superuser privileges, the most popular method is to use Chainfire’s tools – CF-Autoroot, it has been built based on the latest Android 6.0.1 build PC3.
The other method is to use a custom recovery, in this case, you can utilize the TWRP recovery to flash the Chainfire’s flashable SuperSU package. The custom recovery method is usually preferred for those who have planned to flash custom ROMs someday.
Here’s an overview on how to regain root on a Marshmallow update for Sprint Galaxy Note 5 (SM-N920P) by using TWRP:
- Download the latest flashable SuperSU package and save it on device storage.
- Get the TWRP recovery Beta build for Android 6.0, but you can also get it from the official TWRP thread.
- If the TWRP file ended with tar extension, you should flash it with Odin. When it ended with img extension, it should be flashed through fastboot command.
- Once recovery flashing done, reboot into recovery and flash the SuperSU package. If you get a kernel panic on first boot, just hot boot the device (power button + volume down).
- Now open SuperSU app for the first time.
