  • Make sure that your Galaxy S4 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.
    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.

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 Android5.0.1 Lollipop can be downgraded to Android 4.4.2 KitKat but this isn’t confirmed 100% yet, so do not try it unless you’ve done a careful research.

Note: Some of these stock ROM are unbranded while others are carrier branded packages. If you are about to install the unbranded ones on a carrier branded or carrier locked Galaxy S4  (GT-I9505), 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.

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’ check-boxes must be checked. Only the ‘RE-PARTITION’ remains unchecked.

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.

Load the I9505XXUHOB7 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 “I9505XXUHOB7_I9505BTUHOB4_I9505XXUHOB7_HOME.tar.md5″

Start to Flash the I9505 UHOB7 Lollipop 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)”.

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 I9505XXUHOB7.

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:
