Into But there is a problem in both procedures, namely that all data will be lost. To avoid this, you can then make a backup, but with the solution that we are going to give you, all this might not be necessary.
Wandering Into a bit ‘on the net we came across a new really interesting, and that is that the Nexus 4 ( but we believe all the Nexus even if we do not have confirmation ) can be updated to the new build of Android directly from the factory image without losing data.Into This is possible thanks to a trick really be made to the minimum standard installation procedure of the factory image (just omit the command -w when you install the image-occam-versionebuild. zip ) but necessarily require that the bootloader of your Nexus 4 is already unlocked . In fact, if you decide to unlock it at the moment to follow the guide, you will lose all the data anyway. It is also recommended that the system is completely stock, then no root, no custom recovery and no custom ROM on board, but the process should work even if you have a custom recovery, and permits root. In essence, what we have to be stock (original) is the ROM itself.
Into The procedure was tested on our Nexus 4 already upgraded to the previous factory image KRT16O and, on that occasion, it was a reset of the data. Everything went smoothly and, at the end of the installation, we ended up with all of our data on board and with the updated build. We therefore have reason to believe that even those who have a Nexus 4 still on board Android 4.3 Jelly Bean with unlocked bootloader, can update their smartphones to the new build without losing data .
If you want to try, you can follow the guide on our Forum but you should make a backup of the data estimate:
Of course we are still waiting for OTA that we hope will arrive as soon as possible. Even then we will give you a detailed guide on how to install it manually.
