Vivo Y02S Y15C Y15S Dead Repair, Downgrade Firmware

Why Downgrade Vivo Firmware?

Many Vivo Y-series users experience boot loop problems, stuck on logo, or completely dead devices after failed OTA updates or incorrect flashing attempts. The most effective solution is to downgrade to a stable firmware version using professional tools like UFI Box, UMT Pro, or SP Flash Tool.
