Install I337MVLUGOH1 Canada Galaxy S4 SGH-I337M (StageFright) Fix

Manually install the update build to I337MVLUGOH1 on Samsung Galaxy S4 SGH-I337M, the Canadian version. The I337MVLUGOH1 update has nothing more any major changes to take effect but mainly brings fixes to the recent (StageFright) vulnerability. This update has been officially sent out on all Canadian carrier's Galaxy S4 SGH-I337M variants on September 2015. This build will replace the previous released build I337MVLUGOC4 but it's still base in Android 5.0.1 Lollipop OS.

So for those who might missed this update, you may manually install it directly into your Galaxy S4 GH-I337M using the official I337MVLUGOH1 stock firmware itself.

The following is the technical details of the update build I337MVLUGOH1:

Device name: Samsung Galaxy S4
Model number: SGH-I337M
Android version: 5.0.1 (Lollipop OS)
Baseband version: I337MVLUGOH1
Kernel version: 3.4.0-4508315
Build number: LRX22C.I337MVLUGOH1

Yet again, the I337MVLUGOH1 can be downloaded via Over-The-Air or by using Kies 3 / Smart Switch. So for those who did not root nor modified their Samsung Galaxy S4 SGH-I337M you folks may manually check for the update right now by going to the phone’s Settings > About device > Check for Software update. But to those who have had a rooted Galaxy S4, and now might want to unroot and return back to stock 5.0.1 Lollipop, you may grab the stock I337MVLUGOH1 below and flash it with Odin3.


Before you proceed prepare these necessary things as follows so you’ll not mess your phone:
– Create a back-up all your personal data, like: Contacts, Messages, Applications, Pictures, and Videos, so that you will not lose it just in-case something might go wrong after the update.
– Make sure that your Galaxy S4 battery is fully re-charge to ensure stability and to get rid pf power failure issues while updating.
– Close all software, such as KIES suite, Antivirus, firewalls, to prevent the possible conflicts.
– Prepare a personal computer or laptop with Windows OS.

Odin Flashing Procedures:

Odin downloader – Odin3_v3.10
USB Driver – Drivers are here

1) Extract the downloaded firmware or stock ROM. Use winzip, 7zip,winrar or any decompressing program you have in your computer.
2) Run Odin Downloader v3.07 flasher program.
3) Just click on the “AP button” then select and load the binary image.
DO NOT check ‘Re-Partition’ option.
leave these checked: Auto Reboot and F.Reset Time checkboxes.
4) Reboot the Galaxy S4 into Download Mode: Turn it Off first. Now Press and hold the Volume Down, HOME and Power ON button at the same time). You will then presented into a “Warning Message” screen, just press the Volume Up to continue. Once the Android robot and a “Downloading” message appears.
5) Connect USB data cable to Phone. The ID:COM box will highlight and turn to a bluish color when the phone is properly connected and already recognized with Odin.
6) Tick the ‘START’ button when all is set and ready to begin flashing.
7) DO NOT Interrupt, touch nor do anything when the phone is already in flashing progress mode. You’ll messed up the phone if you accidentally interfere the installation. Wait until a word “PASS” appears on the left side of the Odin screen, it is an indication that the installation successfully completes. (If you get failed errors, check the USB connection condition, repeat the whole process)
8.Wait until the phone completely reboots, then unplug it from your computer.

Canada’s Firmware packages are all the same build which sometimes refer to as Bell in the end-result after the manual installation. You might be confused if somehow you installed the Rogers firmware but you'll see the Bell's logo at the welcome screen. If ever you may encounter such problem you may simply change the CSC code according to your network provider.
(NOTE: This process will wipe data, so make a back-up first all of your important data storage.)

1. Get the IMEI number of your phone, by dialing *#06#.
2. Copy the number indicated not including the / xx.
3. Once copied go back and dial this number *#272*IMEI#.
4. Select the correct CSC for your phone’s carrier then tap install.
i.e. BMC = Bell, RWC = Rogers. TLS = Telus, FMC = Fido, and others.
5. The Phone will reset and reboot.
However, if you get bootloops or stuck at welcome screen logo, this is seemingly normal when your device came from a modified and rooted firmware. All you need to do is perform the advanced full factory reset method. This will wipe all the remaining data from your device so again, you should already have the back-up copy of all of files before doing this.
Again, this is only optional just in-case you’ll experience bootloop and lag issues after flashing. Press and hold Volume Up+ Home+Power button, then select the Wipe Data/Factory Reset, to gain a fresher and a cleaner firmware installation.
