How to Install MIUI Recovery ROM on Redmi A3x (klein) via Stock Recovery without a PC

We can update the Redmi A3x firmware via recovery without using computer. However, the Recovery ROM MIUI version must be higher than your current installed version, as downgrading firmware is blocked by Xiaomi.

While user data is retained when flashing via stock recovery, it’s recommended to backup your Redmi A3x’s data before installing, in case of accidental data loss.

Follow the steps to install MIUI Recovery ROM on Redmi A3x using stock recovery mode:

  1. Download the Redmi A3x Recovery ROM zip for your region.
  2. Rename the zip file to “update.zip” if the name differs.
  3. Transfer the update.zip to the root of your phone’s internal storage.
  4. Press and hold the Volume Up and Power buttons together to boot into recovery mode. For some devices you’ll have to press Volume Up, Volume Down and Power buttons to boot into recovery mode.
  5. The update will automatically start flashing if the correct ROM zip is detected.
  6. Once firmware installation completes, your phone will reboot into the updated MIUI version. User data and apps are retained after the process.

For older Xiaomi phones, you may need to manually select “Install update.zip to System One” from the Recovery menu. After install, exit Recovery and boot into MIUI.
