Step 4: Choose Flash Mode

• Download Only: Installs firmware without wiping user data (not recommended for major version upgrades).
• Format All + Download: Wipes everything (use for hard bricks or clean installs). Caution: This erases your IMEI if you don’t have a backup.
• Firmware Upgrade: Best balance – updates system partitions while preserving the userdata partition.
