If you're experiencing auto Fastboot mode and restart problems with your Redmi Note 10 (Mojito/Sunny), here are some troubleshooting steps you can try:
Force Restart: Perform a force restart on your Redmi Note 10 by pressing and holding the power button for about 10 to 15 seconds until the device restarts. This can help resolve temporary software glitches that may be causing the issue.
Clear Cache Partition: Boot your Redmi Note 10 into recovery mode by powering off the device and then pressing and holding the power button and volume up button simultaneously. From the recovery menu, select "Wipe data" or "Wipe cache partition" using the volume buttons to navigate and the power button to confirm. After the process is complete, reboot your device and check if the issue is resolved.
Update Software: Ensure that your Redmi Note 10 is running the latest software version. Go to Settings > About phone > System update and check for any available updates. If updates are available, install them as they often include bug fixes and performance improvements.
Disable Fastboot Mode: If your device is constantly entering Fastboot mode automatically, you can try disabling Fastboot mode. Go to Settings > Additional settings > Developer options > Mi Unlock status and toggle off the "Turn on Mi Unlock" option. This should prevent the device from entering Fastboot mode unintentionally.
Factory Reset: If the issue persists, you can consider performing a factory reset as a last resort. Before proceeding, ensure you have backed up your important data as a factory reset will erase all data on your device. Go to Settings > About phone > Factory reset > Reset phone. Follow the on-screen prompts to initiate the reset process.
If none of these steps resolve the issue, it's recommended to reach out to the official Xiaomi customer support or visit a service center for further assistance. They can provide specific guidance and solutions tailored to your device and its software version.
