⚠️ Essential Requirements Before Flashing

• USB Driver Installation: Ensure the matching manufacturer USB drivers are installed on your Windows PC prior to connecting your phone.
• Battery Level: Always ensure your mobile device has at least 50% to 70% charge to prevent accidental power cuts during low-level writes.
• Original USB Cable: Use an authentic OEM data cable connected directly to your PC motherboard's rear USB ports rather than external hubs.
• Data Backup: Flashing full factory firmware typically wipes internal storage, so create a full backup of all critical personal data beforehand.
