I hv 2 install ver12 clean 'cause OTA updater is not working then. I stuck also @ boot animation for quite a couple of minute(not measured) after that i pull the battery out. Put it in and enter into recovery by 3 key combo. Clean only cache and reboot and it booted normally. Can do it @ ur own risk!!!
