Just flash the 4.4.4 zip in recovery. Don't wipe cache or anything. You won't lose data or root, you might have to flash super user in recovery after. I have survival mode on in super user and did not need to reflash su. The zip can be found here http://forum.xda-developers.com/goog...eodex-t2771010

You will not use otas if you rooting. You will get otas even if you are on a cm rom.

Here is how ota works:

Cheks those system files which have to be updated. If any of those system files is different, then the update fails and will show you an error about unexpected content in xxxx file. If every system files got checked and they are all good for the ota, then it starts patching the files. Then it flashes bootloader (if any), modem (if any), kernel (if any) and copies the recovery image to /system and a script to /system/etc/ then the phone restarts. At booting the phone flashes the new recovery and done.

Install SDK, and make sure that /platform-tools dir is in your PATH (environmental variable) so you can use fastboot and adb from cmd line. Then

1. Download the factory pack from Google
2. Extract it (you can use winrar/7zip, or whatever)
3. Edit the Flash-all script (remove the "-w" if you don't want it to wipe, and the line to flash recovery if you want to keep CWM).
4. Boot your device into bootloader mode, connect via usb
5. run the cmd "fastboot devices" to check your computer see's your device, if not.. you need to configure your drivers
6. run the Flash-all script

That's it.

What is the advantage in doing all those extra steps when you can just dirty flash 4.4.4? I know for a major android version upgrade you'd want to do a clean install, but this is such a minor one. And please don't say something like....to learn how to use fastboot commands.

Those instructions don't require you to know any fastboot commands (the script automates them).
