The Xiaomi Mi 4, released in 2014, is still a popular device thanks to its robust hardware and custom firmware installation capabilities. However, over time, any smartphone starts to slow down, issue errors or require a complete system reinstallation, and factory reset is the universal solution for most software problems, from freezes to viruses.
In this article, you will find three official reset methods (via settings, Recovery and Fastboot), as well as unique nuances for the Mi 4 related to its Qualcomm Snapdragon 801 hardware platform. We will discuss how to avoid a βbrickβ (routine break), what data can be recovered after a reset, and why some versions of MIUI require additional authorization of a Xiaomi account.
Preparation for resetting: what to do before the start
The factory reset completely removes all data from the deviceβs internal memory, including:
- π± Contacts (unless synced with Google or Mi Account)
- πΈ Photos and videos (including screenshots and downloads from messengers)
- π΅ Music, documents and application files (e.g. saves in games)
- π Wi-Fi passwords, app settings and social media accounts
Before you start, follow the mandatory steps:
- Sync your contacts with your Google Account or export them to a.vcf file.
- Copy photos and important files to your computer or cloud (Google Drive, Mi Cloud).
- Write down or take pictures of Wi-Fi passwords (you can find them in Settings β Wi-Fi β Save Networks).
- Make sure the battery level is at least 50% β interruption of the process due to discharge can cause firmware damage.
