For those who don't want to wait for 2.0

If your like me and hate waiting here's a way to update to 5.0.1 using Wug's 1.9.9 from 5.0 without losing data/apps/settings/etc.

Takes about 20 mins give or take start to finish!

Get the factory Image for 5.0.1 for the N7 at google develops:

https://dl.google.com/dl/android/aosp/shamu-lrx22c-factory-ff173fc6.tgz

Extract shamu-lrx22c-factory-ff173fc6.tgz to a folder on your PC (on your desktop somewhere likely the easiest)

- radio-shamu-d4.0-9625-02.55.04.img (rename to radio.img)

- bootloader-shamu-moto-apq8084-71.05.img (rename to bootloader.img)

- image-shamu-lrx22c.zip

Inside the new folder extract from image-shamu-lrx22c.zip

- system.img

- recovery.img (if your not using a custom recovery - if you are you don't need this)

Next get/download the 5.0.1 no forced encryption boot image http://xdaforums.com/showpost.php?p=57406510&postcount=360

rename boot-501-noforceencrypt.img (to boot.img)

Now Start Wug's 1.9.9

Set your device as you normally would N7 running 5.0 then launch

"Advanced Utilities"

In the Fastboot Flash section:

select "Radio/Baseband" read wug's warning hit ok, then browse to the folder were you extracted and renamed all the .img's and select "radio.img" and hit ok,

-Device will reboot into bootloader and flash the new radio, when it completes your device will reboot normally

Once your device fully boots go back to wug's advanced tools Fastboot Flash section:

select "Recovery" (Skip this step if you use/already have a custom recovery installed)

do as before and browse to the folder were you extracted and renamed the .img's and select radio.img and hit ok

-Device will reboot to bootloader and Flash recovery.img once complete your device will reboot normally.

Once your device fully boots go back to wug's advanced tools Fastboot Flash section:

select "Boot [Kernal]" - read the wug's warning then hit ok to continue

You will be presented with a choice:

Select "Other/Browse" and browse to the folder were you extracted and renamed the .img's and select "boot.img" and hit ok

-Device will reboot to bootloader and flash the boot.img, after it will reboot your device normally.

Now one more time after your device finishes booting up go back to wug's advanced tools Fastboot Flash section:

select "System" -read, hit ok and browse to the folder were you extracted and renamed the .img's and select "system.img" and select ok.

-Device will reboot into bootloader and flash the system.img, after it flashed your device will reboot normally (this can take about ten minutes to fully reboot as android upgrades your apps, etc.)

That's it your done - However without root. If you want root back this is simply done as you would normally do it with wug's 1.9.9 (except make sure this time you change your Model Type in basic wug's features to the N7 with 5.0.1)

-Then Select Root option (I had custom recovery already installed from rooting 5.0 so I did not check the option to install Custom Recovery - isn't necessary, unless your on stock recovery and want custom)

From that point follow the onscreen help from wug's as you did the first time you rooted with wug's and all will be happy in the land of 5.0.1

Also if your like me and use tether/hotspot you will need to add

net.tethering.noprovisioning=true back to your build.prop

*I am not responsible if anyone f's this up and fries, explodes or mutilates there device!

-Hope some of you find this useful...
