Android downgrade: undo update

With a downgrade, you can undo an update on your Android smartphone. In this guide, we will tell you exactly how to do this.

Android downgrade: preparation and required software

Before you start, you should make some preparations.

The first step is to backup the entire system. This is essential as all data (at least on the internal memory) will be deleted after the downgrade.
Also make sure the phone is fully charged to avoid data loss.
Now search for your device's flash tool on the Internet. You need this so that you can transfer the desired firmware to your device. You will usually find what you are looking for in relevant cell phone forums. You will often also find the desired firmware for your device there.

These instructions are general because the procedure is often the same - however, minor deviations are possible.

Connect your smartphone to the PC.
Start the flash tool and make sure that your device has been recognized. You can often recognize this by the name of the device, which is displayed in the lower corner.
Start the "Flash mode". You often reach this with a lightning symbol.
Now drag or select the firmware package. In some flash tools, you also have to select them before flashing.
Now start the actual downgrade by clicking the flash again or following the instructions of the program. The downgrade is finished after about 30 minutes.
