For most users, simply entering Fastboot Mode to perform a factory reset via the bootloader menu or to check bootloader status is perfectly safe. If you are unlocking the bootloader or flashing firmware, ensure you have the correct files for the TB-X304 series to avoid bricking your device.

Fastboot Mode is an essential diagnostic and flashing tool for Android devices. It allows you to flash custom recoveries (like TWRP), unlock the bootloader, install system images, or recover a bricked tablet. If you own a Lenovo Tab 4 10 , accessing Fastboot Mode is a straightforward process, though it differs slightly from many other Android devices due to Lenovo’s key combination logic.
