CRITICAL WARNING

Flashing a custom ROM requires erasing your device partition storage completely. Make sure you back up all authenticators, messages, and files before proceeding.

PRO TIPS

Keep your device plugged into a USB 3.0 port on your computer and verify that your drivers are up to date by checking `adb devices` compatibility.
