Step 3: Check Preloader Integrity

• If the device is soft-bricked, try flashing only preloader from a known good stock ROM (very risky if wrong model).
• Alternatively, use a full firmware with preloader from the original manufacturer.

Note: Avoid the "Format All + Download" option if possible, as it can permanently erase critical data like your IMEI and TEE (fingerprint) keys. sp flash tool error status ext ram exception
