========================================
My current Android version is Android 11 and I recently downloaded the latest build (Android 12) for my ASUS ROG Phone 5 on the official ROG website, but when I tried to manually install it, a message pops up saying "System update failed." The update package is on the root folder. I downloaded the file from both my PC and phone, then I tried restarting my phone, but every time I tried to install the update, the same message appeared. What have I done wrong? I need to use Android 12 because my phone has not detected any automatic updates for a while.
