Almost all preloader operations involving partition modifications will result in complete data loss. FRP bypass procedures, bootloader unlocking, and firmware flashing typically require formatting user data partitions. Technicians and users should always perform full backups before attempting any low-level operations. The Y33s preloader mode allows backing up the preloader partition itself, which is strongly recommended before any flash operations—this backup can serve as a recovery mechanism if things go wrong.
