Updating your device security with the latest patch update isn’t a wrong step to take. However, sometimes, the latter result isn’t what you may wish for, and as such, you may want to go back to the previous patch version. Also, if you did an OS upgrade and did not like what you get from the new OS, it is possible to go back to the previous OS you were running on your device. You may not like new features, or you want to wait for the latest bug to be fixed by your manufacturer. Or you lose your favorite feature. In those situations, you may wish to return to your free previous update. This article will extensively treat how you can downgrade or return to a prior security patch or OS on Android devices.
Downgrading your Android OS and Security
Each new Android OS version comes with its patches, and it meant to outperform its predecessor. However, there are some features and tweaks one can perform on older versions, and find it very difficult to do on new releases.
For Android users, all you need do is to downgrade to any of the previous versions, and you’ll automatically return to the last patch security/OS.
First things first, before you start downgrading your device to a previous patch level or OS, you need to run a comprehensive backup and ensure that all your files, contacts, and apps are safe. This is because you will lose everything saved on your device during the downgrading process. You can use device backup software solutions to back up your message histories, and the game progresses as you cannot back up these types of files manually.
Another step to take towards achieving your wish is to unlock your device’s bootloader. The bootloader is an essential component of your device that, if not properly handled, you may brick your device and also void the warranty.
To get started, you need a PC and the ODIN software (for Samsung users) or ADB and Fastboot (for Nokia and Motorola device users).
Things to note
Whether you have rooted your device or not, ensure you run a comprehensive backup first.
Use the right tool to flash your device
Make sure the new security patch or OS is buggy; if it’s something you can manage, please don’t downgrade.
I will give some general ideas based on your manufactures. If you can’t find the methods below, Lookup our firmware section and download the particular tool for unlocking your device bootloader. Different devices work with various tools of flashing; Samsung works with ODIN, and so does every other brand that requires a particular flashing tool. So, you should search for the tool that can flash your device and also search for the procedures.
Alternative, or rather our most preferred way of downgrading any Android device, is by installing a Firmware or ROM running the older version of Android you wish to downgrade to. For example, if your mobile was running on Android Marshmallow, after an update, you got upgraded to Nougat. When you want to downgrade, you should find a ROM for your device that runs on Android 6.0 (Marshmallow). After flashing that ROM, your device will return to the previous OS and patch level.
An excellent place to search for your device’s ROM is on XDA Developers. Also, you can find some wizard guys that can suggest more ways on how you can downgrade your device successfully.
