What is RoTest on Xiaomi and why does it appear?

RoTest (or Test-Keys) is an internal testing mode that is activated on Xiaomi smartphones when using unofficial firmware methods.

• 🔓 The bootloader is unlocked (unlocked bootloader) - this is necessary for installing custom firmware or modified cores.
• 🛠️ Signature test keys installed – instead of official keys Xiaomi used temporary, which makes the device vulnerable.
• 📱 The firmware has not passed full certification - this happens after manual update via fastboot or EDL.

The words "RoTest" or "This device is unlocked" appear at the bottom of the lock screen or in the phone settings, and it doesn't interfere with the main operation of the device, but it does indicate potential risks:

• 🚨 Malware Vulnerability – Test Keys Make Uncertified Applications Easy to Install.
• 🔄 Problems with OTA-Updates – Official updates may not be installed or may not work properly.
• 📵 Service restrictions – some banking applications (e.g. Sberbank Online or Google Pay) can block work on “uncertified” devices.
