How to Downgrade Your Android OS Version

New OS updates for your Android phones are supposed to bring new features and bug fixes. But this is not always the case. Sometimes an update can lead to more bugs than the previous version. Or worse, the update might even break features that worked great in previous versions of Android on your device.

These are some of the times when you might decide to downgrade your device to an older version of the OS, especially when that older version worked great on your device.

Unlike iOS devices, it is quite possible to revert an Android device to an older OS version. Many manufacturers have their own tools to help you with this.

Downgrade Samsung Android Phones using Odin

If you have a Samsung Android phone that you want to downgrade, you’re in luck. Samsung phones are one of the few phones that can easily run an older version of the operating system.

All you need is access to a computer and you can upgrade to an earlier version of your device.

Download the old standard firmware for your device and save it to your computer. A simple Google search will help you find it. Also download the Odin flash tool to your computer.

Extract files from both stock firmware and Odin and run the Odin tool. Press the PDA button in the tool and select the extracted firmware file.

Uncheck the Repartition box in the tool. Check the tool’s Auto Reboot and F. Reset Time options.

Turn off your device. Press and hold the Volume Down, Home Screen and Power buttons at the same time for a few seconds. When prompted, press the volume up button and your phone will reboot into download mode.

Connect your phone to your computer using a USB cable. Then press “Start” in Odin and your phone will start flashing the standard firmware file.

Once the file is flashed, your device will reboot. When the phone boots up, you will be using an older version of the Android operating system

Downgrading your Android phone means that your device has an older version of Android OS. Once it is up and running, you can launch apps that don’t work in newer versions, as well as use anything else that is out of order and no longer works in new Android builds.
