Important Reminders before you install the L520VPUANA7 4.2.2 Stock Firmware

My Galaxy S4 Mini is rooted, will I lose root once the flashing has made?
Yes, you will lose root after flash, but you can still root it again if you want. Learn about the KNOX secure environment that is included to this update  before diving into the plunge.

Will this trip KNOX warranty void flag counter if ever  will enforce root?
Yes, installing any unofficial and unsigned images will surely rip the KNOX warranty flag from the default count of ‘0x0’ to ‘0x1’.

Most Important Note: The Android 4.4.2 KitKat will soon arrive, and definitely it will still come with a protected bootloader. So once your phone received the Android 4.4.2 update sooner, you should not use this Android 4.2.2 stock firmware on top of the Android 4.4.2 Kitkat. Some folks might still use the stock firmware for downgrading purposes. Doing so, it will probably results into an unwanted soft-bricks like stuck at the sprint spark screen.

Disclaimer: Use of this method is solely at your own risk!

  • Make sure that your Galaxy S4 mini 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 S4 Mini.
    Enable USB debugging from your phone’s settings – If you are on 4.3 navigate through Settings>>Developer options>>Enable USB.
  • 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.

Grab these necessary tools:
Odin3.v3.09 find here
USB Driver find here

Install the USB driver of the Galaxy S4 Mini

Install the USB Driver first to get rid of flashing failures. You may 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 ‘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.

Reboot your Galaxy S4 Mini L520  into Download Mode

To reboot the Galaxy S4 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 to the 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 L520VPUANA7 4.2.2 stock  firmware pack

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 it.

Start Flashing or Installing the 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 finish.

Wait until odin tool shows the word 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 just have successfully installed the L520VPUANA7 stock firmware

Go to Settings>About Device>Software info.

Troubleshooting ‘Complete (Write) operation failed Odin error.

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” or “All threads completed. Complete(Write) operation failed. (succeed 0 / failed 1)’.

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 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
