Can you give me a little help doing that?
Here's how (from scratch):
1) Download & install the Android SDK
2) Download & install the proper drivers
3) Download the OTA zip & rename it to "update"
4) Navigate to the "Platform-tools" folder within the SDK & put the update.zip file into it
5) While holding [SHIFT] right-click in an empty spot within the folder & select "Open command window here"
6) Plug in your device
7) Disable "media device"
8 ) Enable "USB debugging"
9) Within the command window, type "adb devices" (without quotations)
Your device should show up with "unauthorized" after it
10) On the device, give the PC the permission
11) Repeat Step 9
Hopefully your device should now appear without "unauthorized". If so, you're now ready to actually update
12) In the command window, type "adb reboot recovery" (without quotations)
This will reboot your device into "Recovery mode" & you'll likely see a little Android guy with a triangle & an explanation mark
13) On the device, hold [POWER] & tap [VOLUME UP]
14) Still on the device, use [VOLUME DOWN] navigating to "apply update via ADB" & select it by taping [POWER]
Your device will now be ready for you to send the update
15) Back on your PC, in the command window, type "adb sideload update.zip" (without quotations)
That will push the update file to your device
16) Watch your device & wait for it to successfully complete
17) On the device, navigate to & select "reboot phone"
That's it, your phone will apply the update just like it would have had you waited for the OTA update.
Keep in mind if you're ROOT'ed you'll loose ROOT.
This method is how I update my Nexus devices using the stock recovery, stock kernel, stock everything - updating using custom stuff will vary.
If you're ROOT'ed, the update will likely fail if you've installed anything to the System folder such as BusyBox or Xposed Framework. To get passed that, you'll need to open those Apps & within the Apps themselves, uninstall the data they've installed to the System. Both BusyBox & Xposed have built-in uninstallers for this.
Hope that helps.
