SP Flash Tool for MT6765 is powerful but dangerous. Always back up nvram, nvdata, protect1, protect2, and preloader before any operation. Without a valid preloader or NVRAM backup, a fully dead or IMEI‑zero device may result. For auth‑enforced devices (Xiaomi, Realme, Infinix), seek the correct signed DA file or use mtkclient (open-source alternative) if SP Flash Tool fails with authentication errors.
After a “Format All + Download”, IMEI becomes 0 or null.
Solution: Use MTK Engineering Mode (Dial *#*#3646633#*#*) or write IMEI using Maui Meta Tool – but only after SP Flash Tool has restored base firmware. sp flash tool 6765
