[T-Mobile Samsung Galaxy Note5] ethanscooter:
[Guide] ["Port"] How to flash Android 6.0.1 on the Galaxy Note 5 from T-Mobile!

The tarball has been uploaded!

To start off, I must say that you can revert from 6.0.1 using this method that I am using. I will break this down into steps and I will try to make it as simple as possible. It took my awhile to figure this out using trial and error so if you like this, click the thanks button.

The KNOX counter is tripped when doing this. I am not responsible for any modifications you do to your device.

What isn't working:

I regret to inform you that after doing another test in-call audio is not working. HOWEVER YOU MUST STILL DO STEPS 11 AND 11a so you can use Cellular Data. In other words; the call fix I provided does not fix call audio but it does fix messaging and data. I recommend possibly using google hangouts to call for now. (not for long, working on a fix right now)

The ability to root via supersu zip (not for long).

Step 1: Download my .zip (this contains my .tar file), from: here and download CF-Auto-root for the T-Mobile Note5.

Step 2: Download the cellular fix for the T-Mobile Note5 from here: Download the "callfix" folder (in a zip).

Step 3: Download Odin (should be anywhere on the internet, google it). Now make a folder on your desktop with the call fix folder zip called "Callfix.zip", my zip that contains my tar file (marshmallow) that you downloaded, and CF-Auto-root (the zip).

Step 4: Make sure everything in the folder looks right, it should look like this:

Step 5: Extract the "Note5601tar.zip" and the "Callfix.zip" to the same folder (right click and click extract here). Now, open the CF-Auto-root.zip and ONLY extract the file called "CF-Auto-Root-nobleltetmo-nobleltetmo-smn920t.tar.md5" to that same folder you have created on your desktop.

Step 6: Rename "CF-Auto-Root-nobleltetmo-nobleltetmo-smn920t.tar.md5" to "CF-Auto-Root-nobleltetmo-nobleltetmo-smn920t.tar" (just remove the .md5). Then, delete any file that you have extracted from (files that end in .zips in that folder). Now make sure your folder looks like this:

Step 7: Drag the Callfix folder that has been extracted to the root directory of your phone (on whatever rom you're on right now).

You are now ready to begin!

Step 8: Boot the phone into download mode (turn the phone off, then hold volume down + home + power at the same time). If you come to a warning screen, press volume up to continue.

Step 9: In Odin (3.10.7) make sure Odin can recognize your device, you should see black text with a blue backing and the word "COM" then a number. Once you verified that your device is recognized, click "AP" and select my .tar file from the folder we made earlier called "Note5TMO601.tar" (the .tar file that was extracted from the .zip). Now click open to select it.

Step 9a: Verify that Odin looks somewhat like this:

Step 10: Click "start" and wait, make sure re-partition is not checked under options!! Don't mess with anything else under options. DO NOT ASSUME YOU'RE ALL SET RIGHT AFTER THIS STEP, THERE IS MORE TO DO!

Step 11 (important): Your phone should reboot into TWRP now, swipe to allow modifications if asked. Go to "advanced > File Manager > sdcard > Callfix > bin" now click the button that is blue and has a folder with a check mark over it. Click "Copy Folder" then click that same blue button again. Now swipe to confirm.

Step 11a: Click "back", "up a level", now do the same process as "step 11" for the folders "etc", "lib", and "lib64".

Step 11b (optional, but recommended): Go home (in twrp) and go to wipe then slide to wipe data & factory reset.

Step 12: Once all the folders in "Callfix" have been moved to "/". Go home (in twrp) and tap reboot > Download.

Step 13 (IMPORTANT, PHONE WON'T BOOT IF THIS ISN'T DONE) : In download mode (close Odin if open), open up Odin, click "AP" then select the file called "CF-Auto-Root-nobleltetmo-nobleltetmo-smn920t.tar". Now click "open" to select the file and click "start". This will not root the phone, even though you will get the SuperSU app. This will simply make the phone bootable (I don't have time to explain how this works).

Step 13a: Your phone will boot and you will see a new Samsung boot animation. It will boot up about half-way the first time, then crash and reboot (this is normal if it happens only a few times).

Step 14: Smack that thanks button and report any issues!

Thanks to: @bigbiff (for TWRP), and @Chainfire (for CF-AUTO-ROOT). Also, thanks to anyone who has ever worked on the Team Win Recovery Project.
