Install N910CXXU1BOB4 Galaxy Note 4 N910C Official 5.0.1 Lollipop Update Firmware

Samsung Galaxy Note 4 SM-N910C (Exynos) official Android 5.0.1 Lollipop update is out.  First firmware build N910CXXU1BOB4 is initially released in Poland. You might wanna ask why is it always in Poland. Well, it seems Poland is Samsung's first choice as a testing ground for initial software updates. But it is not always in Poland though, some other devices first software updates  took place in Russia while sometimes in Germany as well. This is only just the beginning of the official Android 5.0.1 Lollipop update. So therefore, the rest of Galaxy Note 4 N910C users all over the world should also start seeing this update very soon.


Hence the N910CXXU1BOB4 is an Android 5.0.1 version, it may seem it is much stable  version compared to Android 5.0. In 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. But since the  firmware is still fresh we cannot surely tell if its stable or not.  But let's see if there are no any severe issues will be reported once this update reaches out completely to all Galaxy Note 4 N910C users.

Furthermore, one  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.

Build details of N910CXXU1BOB4:

Device: Samsung Galaxy Note 4
Model number: Samsung-SM-N910C
Android version: 5.0.1 (Lollipop OS)
Baseband version: N910CXXU1BOB4

The N910CXXU1BOB4 is now available and can be seen via Over-The-Air (OTA) update and by using Kies, if you’re from those mentioned country. The stock firmware N910CXXU1BOB4 are only for advanced users and are useful for those who might have had a rooted and modified Samsung Galaxy Note 4 SM-N910C and 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 So it is much better to manually install it or otherwise you device may stuck on outdated firmware build.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?
Nup, this an official and signed firmware from Samsung, so flashing official firmware will not trip KNOX.

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 doesn’t 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 N910CXXU1BOB4 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.

Flasher Tool:

Install the USB Driver first to get rid of flashing failures. Also need to extract the downloaded file which is packed in zip or rar files, so that you’ll get the tar.md5 file.

Run and Configure Odin

Run Odin downloader Odin3_v3.09 on your PC desktop. Watch out the check-boxes options on the right top of Odin, ensure that the both ‘AUTO-REBOOT’ and ‘F.RESET TIME’ checkboxes must be checked. Only the ‘RE-PARTITION’ remains unchecked.

Reboot your Galaxy Note 4 into Download Mode

To reboot the Galaxy Note 4 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 download mode then displays an Android robot and say’s “Downloading.. Do not turn off target!!”

Connect your Phone into your computer

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 N910CXXU1BOB4 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 BOB4 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.

Confirm if you successfully installed the stock firmware

Confirm your fresh firmware installed. Go to Settings>About Device, then look for the baseband version and build number must be on N910CXXU1BOB4.

Possible errors that you may encountered, this is based on my own experience while flashing stock firmware on Samsung Android devices. These are just a few hints on how to resolved it.

Q: I got an error message that says “Set-up connection Failed” ?
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?
A: Check for possible program that might interrupt the process, like disabling the anti-virus and closing any running programs. Also try to use another computer or laptop,
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:
Boot in recovery mode
1. Press and hold Volume Up, Home and Power button.
2. Use volume keys to select, Up and Down and Power or Home key to select the option
3. Select Wipe Data/Factory Reset using the Home button.
4. Next select the Wipe Cache Partition
5. Lastly, select Reboot System Now to reboot your Galaxy Note 4 in Normal mode.
