But then again this is the first build of the Lollipop update so don't expect it as 100% stable. There should have some minor glitches could be found once the update is installed.

So it is much better to manually install it or otherwise you device may stuck on outdated firmware build.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.

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.

Disclaimer: Use of this method is solely at your own risk! Please proceed with precautions, for we will not take any responsibility if anything happens to your device by using this guide.

  • 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.

  • For a cleaner installation you should clean-up the memory cache of your device performing factory reset in recovery mode. (read the bottom of this post for the instructions)

  • 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 N910FXXU1BOB4 5.0.1 Lollipop Stock ROM/Firmware

Note: These stock ROMs are unbranded while otheres are carrier branded packages. If you install the unbranded ones on a branded or carrier locked Galaxy Note 4 (SM-N910F), you’ll lose the default logo and apps of that said network operator. It will just de-brand but it and you’ll lose some important apps on that particular network provider.

This stock firmware can be directly flashed on-top of any Android 4.4.4 KitKat versions such as the following:

Flasher Tool:
Odin3_v3.09 – Find it here

USB driver – Drivers are here

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 N910FXXU1BOB4 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. “N910FXXU1BOB4_ N910FOXA1BOB4_N910FXXU1BOB4_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 N910FXXU1BOB4.
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:

Performing Factory Wipe Cache Data Reset

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.

That’s it! Just let us know if you have issues upon flashing the stock N910FXXU1BOB4 5.0.1 Lollipop.
