Unlocking the Bootloader

• 💡 To begin, enable Developer Options by tapping the build number multiple times in 'About phone' > 'Software information'.

• ⚠️ Important Warning: Unlocking the bootloader will factory reset your device, erasing all data. Back up your files, log out of your Google account, and disable screen lock beforehand.
• 🚀 Power off the device, then hold Volume Up + Volume Down and connect the USB-C cable to enter bootloader unlock mode.
• Confirm the unlock by pressing Volume Up once; the phone will then factory reset.

Flashing Custom Recovery with Odin

• 🔌 Power off the phone again. Hold Volume Up + Volume Down and connect the USB-C cable to enter Download Mode.
