Last week, Google start to OTA upgrades Nexus’s products, but some of Nexus 4 users were facing the Android 4.3 upgrading problem.
On 25th of July, Google announced second generation Nexus 7 and Android 4.3 system. Before OTA, Google allows Nexus series products upgrade to Android 4.3 operating system. Some of Nexus 4 users stuck on the ‘X’ screen after the OTA upgrading and the phone cannot boot after that.
From the article discussion of Google Forum, there are many users encountered the upgrading problem, and even try to upgrade many times, but the Android 4.3 upgrading process still does not complete. Users need through the built-in factory setting or reboot into the old version Android to switch on the Nexus 4 and the data information in the phone will be erased as well. So the recommendation before upgrading the phone to Android 4.3, users should back up all their data, contact as well information.
