Not everybody appreciates the changes when new Android versions hit
devices.
whether you're interested in your old version and want to switch back, so in this article "How to Downgrade Your Android Version to a Recent Version",
it’s sometimes possible to downgrade your Android device to a recent version.
Here’s how you do it.
Before we going to start, it’s important to mention the risks
" try on your own risk". Downgrading your Android phone isn’t
generally supported, it isn’t an easy and quick process, and it will almost
certainly result in you losing data on your device. ensure you back up your
phone before you going to perform.
Additionally, it might be possible for your device’s warranty or
potentially brick it! making your smartphone nothing more than e-waste. As
such, we do NOT recommend that you continue unless you have experience developing
your device’s firmware and completely understand the risks involved.
Before Flashing Your Smartphone
How easy it is for you to downgrade your Android depends on the
manufacturer. Some manufacturers make it extremely quick and easy for users to
“flash” firmware images onto their devices while others make it nearly
impossible.
The typical process for flashing requires you to unlock your
bootloader first. Not all Android allow this process, so you’ll check for
yourself if your device manufacturer offers an official method for unlocking
the bootloader, or whether you’ll need to find an alternative or any other
method.
Remembered it! that unlocking your bootloader will wipe your
device’s internal storage or memory. Make sure you have backed up your smartphone
or else your data will be lost forever.
With the bootloader unlocked, you can then flash your Android
version to an older version of Device. Be warned, as unlocking your bootloader
will probably invalidate your phone warranty.
The easiest devices to flash, by far, are Android phones in the
Google Pixel series. Google offers factory images for the Pixel version, with
different builds for Android 9 as well as for 10. You’ll need the Android SDK
installed—with the Fastboot and Android Debug Bridge (ADB) tools—to flash Google Pixel devices.
Both are mixed bags for other device manufacturers, however. Unless
the manufacturer offers them, you’ll need to locate firmware images suitable for
your device. The XDA-Developers forum is a good place to find perfect and
suitable downgraded firmware images for your individual Android phone.
Before searching on other websites, search your company's official
website for firmware images.
Flashing non-Google phones is possible with the Fastboot method,
although third-party tools do exist for other companies of Android phone's like
Samsung.
Manually Flashing Using Fastboot and ADB
The only “official” method for downgrading your Android phone is
the Fastboot method. While not every company or manufacturer encourages it, the
Facebook tool is available from Google for you to use and should work with
official firmware images from almost all Android brands and companies.
To proceed, you just need to be able to unlock your bootloader and
have a perfect and suitable firmware image for your device and carrier. Make
sure USB debugging is enabled on your
Android phone before you start this process.
Whether you’ve found a perfect and suitable firmware image, your the bootloader is unlocked, and you have the Android SDK installed, connect your
Android devise to your PC or laptop. While the steps below are for Windows 10
users, the ADB, and Fastboot commands should work in a similar way on macOS and
Linux.
Now simply open the file explorer and head to the saved location of
your device SDK installation. Make sure the device image files you need to
flash are here, too. These usually come as a ZIP file with multiple IMG files
held within. Unzip the contents to this location.
In the folder, hold the shift key button on your keyboard,
right-click inside the window, and click the “Open PowerShell Window Here”
button. On macOS or Linux, navigate to this folder using the Terminal
application.
Type ADB devices in the Windows PowerShell window to make sure you're An android device is detected. If it is, type ADB reboot bootloader to restart
your device and boot into the Android bootloader menu.
If the ADB commands don’t work, type .\adb instead.
Most manufacturer firmware comes with a “flash-all” script that
flashes all the relevant image files to your device. Once your device is in the
bootloader mode, type flash-all to start the flashing process.
If the flash-all script doesn’t work, you will need to manually
flash the individual items in the folder. Type the following commands into
Windows PowerShell (or Terminal) hitting the Enter key between each step:
- fastboot flash bootloader <bootloader name>.img
- fastboot reboot-bootloader
- fastboot flash radio <radio file name>.img
- fastboot reboot-bootloader
- fastboot flash -w update <image file name>.zip
Once this process is complete, your phone should restart. If the
flashing process was successful, your device will now be running the downgraded
firmware image.
Using Third-Party Flashing Tools
Thanks to the work of volunteer developers, third-party flashing
tools are available. These manufacturer-specific firmware flashing tools offer
you an alternative method to flashing your firmware without using the Fastboot
method.
If your device doesn’t have a third-party tool, it’s best to use
the Fastboot method listed above.
As we all know that Samsung phones can make use of Odin to
downgrade their phones. This is one of the best-known flashing tools outside of
the official Fastboot method.
The Odin interface is not the most beginner-friendly, but it will
allow you to flash onto some brands phone such as Samsung, including the latest
unlocked Galaxy phones.
Remembered! that some smartphone companies carriers lock down the
bootloader on Android sold through its stores. These network operators can be
reluctant to allow their users to unlock their phones unless the Device is
completely paid for.
Additional tools are available for other companies. This post at
XDA developers list various flashing
tools for Motorola devices, including the recommended RSD Lite. Huawei device
owners can use the Huawei Recovery Updater (HuRuUpdater) instead.
We can’t stress this enough: These tools aren’t guaranteed to work,
and they don’t come with approval from manufacturers. Whether you use a
third-party tool or the Fastboot method, the risk of bricking your device
remains the same.
Again, before you begin, make sure you’ve backed up your phone
before you make any attempt to flash your device as your phone will be wiped
during the flashing process.
