What to do before an XIAOMI Buds 3T Pro hard reset?

First of all, back up all the files you wish not to lose (do it using your computer or an SD card). Backing up applications on XIAOMI Buds 3T Pro is not advisable as they might be the reason your device is malfunctioning. After the hard reset, install them one by one monitoring the reactions of your XIAOMI Buds 3T Pro.
After having saved all personal data, delete them in order to prevent the accidental formatting while performing the hard reset operation.
