Install N910CXXU1BOC3 Galaxy Note 4 N910C Official 5.0.1 Lollipop Update Stock ROM

Samsung Galaxy Note 4 SM-N910C (Exynos) official Android 5.0.1 Lollipop update N910CXXU1BOC3. The latter is now released and only available in Poland once again.  Burt for those advanced users that wants to upgrade right now, you can do so by flashing the official stock firmware build LRX22C.N910CXXU1BOC3. It is exactly the same and the original firmware that was directly pulled out from Samsung Kies server.

Since we already seen the initial 5.0.1 lollipop update  N910CXXU1BOB4 last month, so the N910CXXU1BOC3 is another Android 5.0.1 N910CXXU1BOC3 Note 4 Lollipopversion released this year so far.  Some changes you can find in N910CXXU1BOC3 is that the silent mode is back. There is this thing that says "Do not disturb" along with a timer options where you can find it in Sounds and Notifications settings.

The best thing I like in 5.0.1 Lollipop update is the “Slow Motion” feature that looks like the ones we have found in iPhone 6. Along with the key-features of 5.0.1 is the “Smart Lock” and some new stuff that the Android 4.4.4 KitKat could not offer. The 5.0.1 Lollipop it is much better when it comes to battery life performance, you can tell that the battery percentage will not drop fast enough during a long cycle of use.

The N910CXXU1BOC3 is now available and can be seen via Over-The-Air (OTA) update and by using Kies, if you’re from the mentioned country. The stock firmware N910CXXU1BOC3 is only for those advanced users and are useful for those who might have had a rooted and modified Samsung Galaxy Note 4 SM-N910C and have missed this update. You can use the manual method instead if the device will no longer receive any official update via Kies or OTA update. So it is much better to manually install it or otherwise you device may stuck on outdated firmware build.

FAQ’s During Flashing/Install

Q: Will this trip KNOX warranty void flag counter to 0×1?

No, this an official and signed firmware from Samsung, so flashing official firmware will not trip KNOX.

Q: My Galaxy Note 4 is rooted, will I lose root?

If your device was rooted you will lose root right after the installation finished as the device OS will then restored back to the official default settings.

  • Make sure that your Galaxy Note 4 battery is fully charge.

  • Stock Firmware packages comes in two formats the ‘Full-Wipe’ (delete your stored data after flashing) and the ‘Non-Wipe’ (it does not delete your phone’s stored data) but it is highly recommended to make a back up all important files stored from your phone’s internal memory – contacts, messages, etc. before flashing no-matter if it is Full-Wipe or Non-Wipe, just to be safe and ensure that your stored data are in safe if something went wrong during the flashing process.

  • Use a PC or laptop that runs in Windows OS, with a good and perfectly working USB serial port. Odin will not work on MAC OS.

  • Use the supplied USB cable for your Galaxy Note 4.

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

  • TURN OFF the Reactivation Lock – juts tap on Settings>>Security>>Reactivation Lock and then unchecked the Turn Reactivation lock on.

  • Ensure that KIES is closed and not running in the system tray! Kies and Odin are both created by Samsung but Kies will interrupt and doesn’t like Odin, it will block you from flashing.

However, the Android 5.0.1 Lollipop still comes with a protected bootloader that might cause issues when you try to install any unofficial or unsigned firmware builds. The Android 5.0.1 Lollipop can be downgraded to Android 4.4.4 KitKat but this isn’t confirmed 100% yet, so do not try it unless you’ve done a careful research.

Download the N910CXXU1BOC3 5.0.1 Lollipop Stock ROM/Firmware

Note: These stock ROMs are both unbranded and carrier branded stock firmware packages. If you install the unbranded ones it on a branded or carrier locked Galaxy Note 4 (SM-N910C), you’ll lose the default logo and apps of that said network operator. While installing the unbranded ones over a carrier locked or branded devices it will just de-brand it and you’ll lose some important apps on that particular network provider.

Once you already reboot the phone in download mode, simply connect the phone to your PC or laptop USB. In Odin window – the ID:COM box will turn to blue color and indicates the COM port number and a word “Added” on a log 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.

Load the N910CXXU1BOC3 5.0.1 Android Lollipop stock

The stock firmware is pack in a single .tar.md5 file only. Now, you need to just simply click on the AP button, then browse to the folder where the file you have previously extracted and then select and load the firmware file like this. “N910CXXU1BOB4_ N910COXA1BOB4_N910CXXU1BOB4_HOME.tar.md5″

Start to Flash the BOC3 5.0.1 stock

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 finish.

Wait on PASS!!

When the Stock Firmware installation successfully completes, you will then see a word “PASS” in Odin. This indicates that the flashing was already finish, 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.

A: 1. Check your USB connection from the phone to PC,

2. Connect to another PC USB port

3. Check and or try to another USB cable

4. Re-install the USB driver.

Q: Odin just suddenly stuck in the middle of nowhere while in flashing progress, it isn’t responding at all?

Q: I experienced bootloop or the phone just stuck on Welcome Logo (phone always stop at bootanimation) and it won’t boot normally?

A: This is eventually happens if your device came from custom firmware but you can fix it via recovery mode option, do this:
