upgrade Nexus 4 to 4.4

I’ve upgraded my Nexus 4 with no issues, here’s a guide to help you do the same, without wiping your current content, to upgrade Nexus 4 to 4.4!

First: Check out this link, download the file, and check the md5
Then follow these directions from here:
Assuming you have fastboot already, this is what I did after downloading the factory image on my ubuntu 13.10 box:

tar xzvf occam-krt16o-factory-75ccae7a.tgz
cd occam-krt16o
zip -d image-occam-krt16o.zip userdata.img

Above step is to avoid wiping my data. Now I put my phone in the boot loader and did this:

fastboot reboot-bootloader
fastboot flash bootloader bootloader-mako-makoz20i.img
(at this point I verified that the bootloader version is actually newer)
fastboot reboot-bootloader
fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1700.84.img
fastboot reboot-bootloader
(at this point I verified that the radio is a newer too)

And finally:
fastboot update image-occam-krt16o.zip
