One UI 9.0 update bricks some Galaxy A57 units at boot

After the stable One UI 9.0 (Android 17) rollout outside South Korea, some Galaxy A57 phones fail to boot, showing an "Access Denied" error or a raw XML tree. Samsung has not explained the cause or given a fix date; users are advised to hold off on updating.

• Some Galaxy A57 units fail to boot after installing One UI 9.0
• Reports on Reddit and X point to an XML file error
• The Korean Galaxy Quantum 7 got the update without complaints
• Temporary workaround: boot into Safe Mode, then restart normally
