We were as surprised as you when we learned that a Marshmallow update for T-Mobile Galaxy Note 5 (SM-N920T) is already out to one user, who cared enough for the rest of Android fans to create and share a system dump out of it. Thankfully though, an Odin flashable TAR has now been made of that dump, which allows you to install the leaked Samsung Android 6.0 Marshmallow update on your own T-Mobile Note 5.

Yes, you would soon have a custom ROM based on leaked official Marshmallow update on other unlocked Note 5 sets like international one (SM-N920C/G/i).

Although this is official Samsung Marshmallow update for Note 5, and isn’t based on AOSP code, this still breaks yours device’s warranty.

That’s because it’s only a system dump, code for system partition, and lacks official boot and recovery images. So, installing this will break KNOX flag, and your device’s warranty along with KNOX security will be gone.

That said, if you love latest OS, then give it a go. If you have rooted or installed TWRP recovery on your Note 5 earlier, then your warranty is already void, and KNOX flag is already broken, so you don’t need to worry about them anymore now.

Disclaimer

Installing an official firmware through Odin doesn’t void your device’s warranty, but it remains an unofficial process and thus you need to be cautious of it. In any case, you only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.

Backup!

Backup important files stored on your device before proceeding with the steps below, so that in case something goes wrong you’ll have backup of all your important files. Sometimes, Odin installation may delete everything on your device!

Step-by-step Guide

Step 1. Download the Odin software and firmware file from above.

Step 2. Install Samsung Note 5 driver (use method 1 there!) first of all. Double click the .exe file of drivers to begin installation. (Not required if you have already done this.)

Step 3. Extract the firmware file now. You can use a free software like 7-zip for this. Install 7-zip, then right click on firmware file and under 7-zip, select ‘Extract here’. You should get the a file in .tar format now. We will be loading this file into Odin, to be installed on device (in step 9 below)

Step 4. Extract the Odin file. You should get this file, Odin3 v3.10.6.exe (other files could be hidden, hence not visible). Disconnect your Note 5 from PC if it is connected.

Step 5. Enable OEM unlock on your device.

  • Go to Settings > About device. Now tap on ‘Build no.’ for about 7-8 times, until you get the toast message ‘You’re now a developer’.
  • No go back to Settings > Developer options. Now, locate ‘OEM unlock’ option and enable using its toggle button. Tap on OK to accept the pop-up message.

Step 6. Boot Note 5 into download mode:

  • Power off your Note 5. Wait 6-7 seconds after screen goes off.
  • Press and hold the three buttons Volume down + Power + Home together until you see warning screen.
  • Press Volume Up to continue to download mode.

Step 7. Double click on extracted file of Odin, Odin3 v3.10.6.exe, to open the Odin window as shown below. Be careful with Odin, and do just as said to prevent problems.

Step 8. Connect your Note 5 now using USB cable. Odin should recognize your device. It’s a must. When it recognizes, you will see Added!! message appearing in the Log box in bottom left, and the first box under ID:COM will also show a no. and turn its background blue. Look at the pic below.

Odin 3.10.6 Added message

  • You cannot proceed until you get the Added!! message, which confirms that Odin has recognized your device.
  • If you don’t get Added!! message, you need to install/re-install drivers again, and use the original cable that came with device. Mostly, drivers are the problem (look at step 2 above).
  • You can try different USB ports on your PC too.

Step 9. Load the firmware file into Odin. Click the AP button on Odin and then select the .tar file that begins with AP from the extracted files from step 3.

  • Info: When you load files into Odin, it checks the md5 of firmware file, which takes time. So, simply wait until that’s done and the firmware file is loaded. Don’t worry if Odin gets unresponsive for a while, it’s normal. Binary size will also show up in Odin.

Step 10. Make sure Re-partition check box is NOT selected, under the Options tab. Don’t use PIT tab either. Go back to Log tab btw, it will show the progress when you hit start button in next step.

Re-partition Remains Off

Step 11. Click the Start button on Odin now to start flashing the firmware on your Note 5.Wait till installation is finished, after which your device will reboot automatically. You’ll get PASS message as shown below upon successful installation from Odin.

  • If Odin gets stuck at setup connection, then you need to do this all again. Disconnect your device, close Odin, boot device into download mode again, open Odin, and then select the file and flash it again as said above.
  • If you get FAIL in the top left box, then also you need to flash the file again as stated just above.

Step 12. First start of the device may take time, so wait patiently again. Check the Settings > About phone to confirm new firmware.

Step 13. If you face force close errors on apps, then fix that by doing a factory reset. Do this:

  • Power off your Note 5. Wait 6-7 seconds after screen goes off.
  • Press and hold the three buttons Volume Up + Power + Home together until you see Samsung’s logo. You’ll soon enter recovery mode.

That’s it.
