Install G900W8VLU1BOC2 Official 5.0 Lollipop on Canadian Samsung Galaxy S5 SM-G900W8 (Stock Firmware)

A stock firmware with build version number G900W8VLU1BOC2, it's the Android 5.0 Lollipop update which was officially rolled out to Canadian Samsung Galaxy S5 SM-G900W8. The G900W8VLU1BOC2 contained the security patch to address the recent Android OS vulnerability in pictures and video messaging (MMS). This recent security flaws found in Android OS is so-called ("Stagefright") bug. Many Android smartphones and tablets have been also receiving the same update that brings nothing more but are equipped with the Google's Security Patches to fix the Stagefright.

So for those who may not be able to get the  G900W8VLU1BOC2 5.0 via Over-The-Air OTA update. If somehow due to the fact if the device have been rooted or installed with a custom firmware, the only way to get the G900W8VLU1BOC2 5.0 update is to manually install it back to the phone. This process will not only remove the root and any modified system images running in the device system but as well restore back the phone to its official firmware settings.

Feature/Enhancement of G900W8VLU1BOC2 update:

Also Addressed  at Bell S5 support page.

Important Note:

  • Make a full backup of all important data stored from your phone and saved it in your computer. I highly recommend this as we are going to perform a full factory data reset, wipe cache to obtain a fresher and clean installation. Don’t be lazy.

  • Perform a Full wipe factory data/reset before and after flashing so your phone’s memory cache will be cleaned-up as those remained data out there will cause trouble. This resolves and help to get rid of lag issues once the installation is finished. Read at the bottom of this post on how to perform a factory reset.

  • Re-charge your phone’s battery, fully charge just to make sure.

  • Use a PC with perfectly working USB serial port.

  • Use the supplied USB cable for your Samsung Galaxy S5.

  • Enable USB debugging from your phone’s settings – Settings>About Phone, then scroll down to the build number and tap that number for around 7-times ’til the Developer option appears. Hit back to Home>Settings>Developer option>Enable USB debugging.

  • TURN OFF the Reactivation Lock – This is only needed if you already turned-it-ON, from which you cannot modify the system when it’s turned-ON. Go to Settings>Security>Reactivation Lock and then uncheck the Turn Reactivation lock on.


Q: My Samsung Galaxy S5 is rooted, will I lose root once installed the official firmware?

If your device is currently rooted you will lose root after flash, but you can still root it again if you want.

Q: Will this method triggers KNOX Warranty counter to 0x1?

No, this is an official and signed Android 5.0 Lollipop firmware released by Samsung, so flashing official firmware will not harm KNOX warranty void flag.

Install the USB Driver first to get rid of flashing failures. You may also need to extract the downloaded file which is packed in a (zip) so that you’ll get the (tar.md5) file.

Run and Configure Odin.

Run Odin multi-downloader Odin3_v3.09 on your PC desktop. Watch out the check-boxes options on the right top of Odin, ensure that the ‘Phone Bootloader Update’ (only if your device runs on 4.3), ‘AUTO-REBOOT’ and ‘F.RESET TIME’ checkboxes must be checked. Only the ‘RE-PARTITION’ is unchecked.

To reboot the Samsung Galaxy S5 SM-G900W8 into download mode, you need to turn the power off. After it completely shut off, just press and hold the Volume Down key, Home button and the Power ON/OFF button simultaneously.

You should then prompted into a warning screen and asking you to press volume up if you want to continue or volume down to cancel, just simply press volume up to get into download mode. The downloads mode then displays an Android robot and say’s “Downloading.. Do not turn off target!!”

Connect the SGS 5 Phone to PC.

Once you already reboot the phone in download mode, simply connect the phone to your PC.

In Odin window – the ID:COM box will turn to blue color and indicates the COM port number and a message says “Added” on a log cat box will prompt you that the device is already detected or recognized by Odin. Your COM port number might be different from mine. If you do not see a COM port number then there’s something missing or wrong. You may read again from the top of this post.

The stock firmware is packed in a single .tar.md5 file only. Simply click on the AP button, then browse to the folder where the file you have previously extracted and then select and load it.

“ G900W8VLU1BOC2_G900W8OYA1BOC2_HOME.tar.md5?

Start on Flashing the G900W8VLU1BOC2 stock firmware.

Once if all set and ready to fire-up, hit the “START” button in Odin to begin flashing the stock ROM. Do not ever interrupt the phone while already in flashing progress, like disconnecting the cable or turning off the device. Just wait until it completely finishes.

Wait until you see the PASS!! message.

When the Stock Firmware installation successfully completes, you will then see a word “PASS” in Odin. This indicates that the flashing already finishes, and on the log box it says “All threads completed (succeed 1 / failed 0)”. The phone will just then automatically reboot, then it’s about time to remove it from PC or laptop USB connection.
