Because the SM-N910W8's hardware is identical to the SM-N910T (they're both labeled SM-N910T under the battery), with some slight changes, the SM-N910W8 stock firmware will run flawlessly on our T-Mobile variant.

There two parts to this post: the first part has a pre-made flashable version for those who just want something working. The second part explains how to port it yourself starting from the stock Odin tar.md5 archive.

Enjoy!

Flashable version

1. Factory reset


2. Flash the flashable Canadian N910W8VLU1BOC4 stock ROM from https://mega.co.nz/#!Qwp3WQAC!c_CaIG...gAEctNW52YBK_U


3. Flash SuperSU


4. Reboot


5. Set up the T-Mobile APN (see: https://support.t-mobile.com/docs/DO...8#apn_settings).

Porting and installing manually

1. Download the Canadian N910W8VLU1BOC4 stock ROM from https://mega.co.nz/#!hxYXzYhJ!M_KCVi...YJeElzv9xZpPgI
   
   If you want, you can download a different version from http://sammobile.com or http://samsung-updates.com because we will discard the CSC carrier modifications.
   


2. Extract cache.img.ext4 from the Odin tar.md5 archive and extract recovery/sec_csc.zip from that ext4 image.
   
   On Windows, you can do this by using CacheRipper: http://forum.xda-developers.com/gala...e-img-t1702861
   
   On Linux, you can do this by downloading simg2img (or compiling it from AOSP) and then running:
   
   
   
   

   Code:

   
   

   ---

   simg2img cache.img.ext4 cache.img
mkdir mnt
sudo mount -o ro cache.img mnt
cp mnt/recovery/sec_csc.zip .
sudo umount mnt
rmdir mnt

   ---

   
   


3. Open sec_csc.zip and remove the following directories and files. We don't want any of the carrier customizations, so only the language files are kept. They are needed for SNote and Action Memo.
   • system/csc
   
   
   • system/etc
   
   
   • system/CSCVersion.txt
   
   
   • system/SW_Configuration.xml
   
   


4. Open META-INF/com/google/android/updater-script from sec_csc.zip and add the following to the top.
   
   
   

   Code:

   
   

   ---

   mount("ext4", "EMMC", "/dev/block/platform/msm_sdcc.1/by-name/system", "/system", "");

   ---

   
   


5. Remove all images except for "system.img.ext4" from the Odin tar.md5 archive (keeping the *.mbn files will hard brick your device! Don't do it!)


6. Factory reset


7. Flash the new tar.md5 (containing only system.img.ext4) using either Odin or Heimdall


8. Reboot into recovery


9. Flash the modified sec_csc.zip


10. Flash my patched kernel from https://noobdev.io/canada/Kernel_N91...C4_Patched.zip.
    
    This is the stock kernel, but with tima and dmverity disabled, the CONFIG_SEC_RESTRICT_* options disabled, and a patch from CyanogenMod added to allow brightness adjustment on our old 4.4 bootloader. The GPL kernel source is linked below.
    


11. Flash SuperSU


12. Reboot


13. Set up the T-Mobile APN (see: https://support.t-mobile.com/docs/DO...8#apn_settings).


14. Set "ro.securestorage.support" to false in /system/build.prop (or else WIFI passwords won't persist across a reboot)


15. Disable SecurityLogAgent with TitaniumBackup or delete /system/app/SecurityLogAgent to remove the KNOX notification.
