Official firmware for the Boost Celero 5G (WTCELERO5G) is primarily available through Over-the-Air (OTA) updates, while community-vetted, full flashable files are hosted on platforms like AndroidFileHost and Needrom. Manual flashing requires the SP Flash Tool for Mediatek chipsets, and users are warned against flashing generic NVRAM files to avoid IMEI loss.
