How to Fix Xiaomi HyperOS 3 System Update Verification Failed

Data recovery from a Xiaomi phone with a broken power button is possible if the phone still boots, charges, or has USB debugging enabled. The safest path is to keep the device powered, unlock the screen if possible, connect to a computer, and export photos, files, contacts, and app data before the battery drains.

Steps

Check whether the phone is still on or can wake with charging. Connect the Xiaomi phone to a charger for at least 15 minutes. Try waking the screen with double tap, fingerprint, face unlock, or a connected USB cable if supported.
Unlock the phone and keep the screen active. Use fingerprint, pattern, PIN, or facial recognition if available. Disable auto-lock temporarily from Settings if access is possible, since a broken power button recovery often fails after the screen turns off.
Connect the phone to a computer and select file transfer. Use a USB cable and choose File Transfer/MTP on the Xiaomi screen. Copy DCIM, Pictures, Downloads, Documents, and WhatsApp or other app folders to the computer.
Use cloud sync or Xiaomi account options if local transfer fails. Open Xiaomi Cloud, Google Photos, Google Drive, or app-specific backup settings from the phone. Sync recent photos, contacts, notes, and messages before the battery drops.
Arrange hardware repair only after data export. Button replacement may trigger a restart during service. Complete the xiaomi broken power button recovery first if the device still responds.

Quick Tips

A Xiaomi phone that is already powered on has a much higher recovery chance than a fully powered-off device.
OTG accessories, ADB commands, and PC recovery tools usually need prior permissions or USB debugging already enabled.
Some Xiaomi models can wake the display by plugging in the charger, even when the power button is unusable.
If the button is stuck and causes repeated restarts, stop pressing around the frame and stabilize the device before copying data.

Can data be recovered if the Xiaomi phone is completely off?

Recovery is limited if the phone cannot boot. A repair technician may need to restore temporary power-button function first.

Can files be copied without unlocking the Xiaomi phone?

Usually not. Most Xiaomi devices block internal storage access until screen unlock and USB permission are completed.

💡Protip:

If the Xiaomi phone stays powered on long enough for computer access, a phone management tool such as Dr.Fone can help export photos, videos, and other files in one session before hardware repair.
