Android : Restore Original Firmware

One of my old phone have suddenly been bricked and kept on looping at reboot (boot loop) and yes its a Samsung Galaxy J5 2016 phone. The root caused was the firmware file corruptions during Android update. To fix this I need to manually download the original firmware version and to restore it as all other methods such as "Wipe Cache Partition" and "Wipe Data & Factory Reset" have all failed.

(A) BOOT INTO "DOWNLOAD" MODE.

1. Ensure the phone's battery have at least 50% of charge.

2. Standby the original Micro USB cable (must be data type cable).

3. Download the flash utility called ODIN (https://www.getdroidtips.com/odin-download-latest-odin-software/)

4. Download Samsung KIES software, this is only required if you haven't install the Samsung USB Drivers yet (https://www.samsung.com/my/support/kies/).

5. Download the latest firmware and search for your corresponding model (mine is J510GN, Malaysia), its the same source (https://updato.com/). You will need to register an account in order to download.

6. Ensure the phone is Power-Off.

7. Press --> HOME + VOLUME DOWN + POWER simultaneously and hold it for a few seconds.

8. When prompted, press --> VOLUME UP to proceed to download mode.

(B) CONNECT PHONE TO COMPUTER.

1. Ensure that Samsung KIES or Samsung USB drivers is already installed in the computer.

2. Once the phone is connected to the computer, wait for a few seconds for it to auto-detect and configure.

3. Now open ODIN tools.

4. Once ODIN is loaded, you should see the status "ADDED" and your phone is recognized.

(C) START FLASHING THE PHONE.

1. Extract the downloaded firmware, you can use any compression tools such as 7Zip.

2. In ODIN screen, click --> AP button and search for the downloaded firmware.

3. Now press --> START button to start uploading the firmware into phone. This may take some times so be patience with and don't disconnect or power-off the phone.

4. Once everything is completed, your phone will auto-restart itself. You can now disconnect it from the computer.

5. The first initialization will be very slow and the updating is also very slow, leave it run automatically and at times it may seems to be freeze (but it wasn't), also it will auto-restart several times thus please be very patience during this process.

6. Finally, you will be able to see the "Samsung" logo at boot and will eventually displayed the "Home" screen. That's simple.
