Warning — Firmware Flashing Risks!
If you flash the wrong firmware or interrupt the process, your Positivo SP2 may be permanently bricked and unrecoverable. Using incorrect drivers or an unreliable USB cable can cause flashing failures, which may result in loss of data or make the phone completely unusable. Always ensure your device matches the exact model and build before proceeding. Backup all your data; flashing will erase user data entirely, and recovery is not guaranteed. Power failures or disconnecting the cable while flashing can irreparably damage the SP2’s mainboard.
