Unbrick the N920W8 locked to Marshmallow v6.0.1 Bootloader

Finally figured it out! Here are the exact step by step instructions I used to unbrick my soft-bricked N920W8 phone, load the F3 Rom, and finally get voice working after fiddling with it for over 10 hours of trial & error and researching! Hope it helps someone!

Rogers N920W8 Variant (Carrier Locked)

With Marshmallow Bootloader

(restricted to v6.0.1 / will not run v5.1.1 lollipop)

Synopsis: After failed attempt at an install of another custom rom (Extreme Debloated) which including flashing the N920W8's Bootloader (with the file BL_N920W8OYA2BPC5 in Odin/BL Option) which is the latest Marshmallow Version, the phone got stuck at the Samsung Boot Screen with red message Recovery is not SEAndroid Enforcing" during power on. Unable to power off.

Important: To get the phone unstuck you need to reset it by hitting Volume Down / Power Simultaneously, once it shuts off <immediately> hit Volume Down/Home/Power to get to Download Mode or Volume Up/Home/Power to get to Recovery Mode (Stock/TWRP Depending on what you have). This must be done immediately during the 1 or 2 seconds the phone is powered off / screen is dark / blank, otherwise it will attempt to boot and you will have to repeat the process. This works also if you are stuck in download mode, bootloop or boot screen.

Attempts to restore to stock Rogers v5.1.1 firmware or the previous boot loader via ODIN fails with "sw rev check fail device 2 binary 1"; this is due to the fact that the boot loader is locked to the newer version 6.0.1 and will not take anything lower.

The Fix:

1) Downloaded Telus Version of v6.0.1 since Rogers is not available yet from SamMobile (File Name N920W8VLU2BPC5_N920W8OYA2BPC5_TLS.zip) and reflashed via ODIN (AP Option) and phone started with no issues.

Note 1: During first boot the system will be on the ANIMATED Samsung Logo for up to 10 Minutes! This is normal!

Note 2: This image appears to be the Rogers Stock Firmware with default Rogers Apps even though it says Telus on the download page. Only Languages available: English (CA/US), French, Spanish, Korean, Chinese (Trad/Simp). :(

2) Went through the initial setup wizard then downloaded CF Auto Root (File Name CF-Auto-Root-nobleltebmc-nobleltebmc-smn920w8.tar.md5) and Flashed via Odin v3.10.6 using the AP Option.

3) Installed Flashify via Google Play Store and used that to install TWRP chosing Note 5 GSM / Noblelte / twrp-3.0.2-1-noblelte.img as the file to flash.

4) Downloaded Infinity F3 Custom Rom (File Name [6.0.1]I N F I N I T Y - F3 Marshmallow[samsungvn.com].zip) then verified using WinMD5 to match checksum of "aefcd4aa33be6c3dd65fceb69fc3bc18" and transferred the ROM to Internal Storage of phone.

5) Restarted phone to TWRP Mode and made backup of all options (Boot/System/Data/Cache/Modem/EFS).

6) In TWRP: Performed Wipe of Dalvik/ART Cache, System, Data, Cache

7) In TWRP: Select Install and chose the Infinity F3 ROM File which loads the Aroma Installer Installation Wizard

8) In Aroma: Choose the option to wipe all data (yes wipe a second time to prevent set_metadata_recursive some changes failed error!), then follow instruction to complete wizard and restart.

9) Note 3: During first boot the system will be on the ANIMATED Samsung Logo for up to 10 Minutes! This is normal!

10)Go throug setup wizard when it comes up after the long wait. (All languages available now!!!:D)

Everything including LTE Data working except voice calls / SMS at this point.

11)To fix this, download the file Marshmallow_N920W8_N920T_Data_Voice_Fix_Test6.zip (MD5:8c92467c457408fa4014c101d7743778). It can be found on the androidfilehost.com website as fid (File ID 24499762635998028).

12)Copy the Data/Voice Fix to Internal Storage then reboot into TWRP and, make full backup first (since we already got this far), and flash the fix to patch the problem.

13)Restarted and if no phone calls / SMS are getting through, try toggling between settings such as 2G/3G/LTE, Flight Mode, Deactivate and Reactivate Data. After doing this everything was back to normal. Inbound/Outbound calls and SMS works once again!

14) *Optional* - If your phone is carrier locked try swapping a different SIM Card and after rebooting. In my case it properly prompted me for the phone unlock code unlike some other custom roms that may require you to temporarily revert to stock rom in order to unlock!

15)Finally wrote documentation, made the "Golden Image" using TWRP Backup, downloaded it to my PC and stored it in a safe location.

16) Enjoy!
