I figured id post this as there are posts all over the place saying do this and do that so we needed a clear and concise post laying out the process for everyone. To be clear there are a few different ways to go about this and i will regularly update as new stable ways come about

Disclaimer: Only YOU are responsible for what happens to your phone while doing anything, including flashing any ROM So BACKUP BACKUP BACKUP AND THEN BACKUP SOME MORE!

Method 1: (recommended)
Follow the directions in the first post Here - (Credits: SuperR, Junkie2100, Mgiddeon, APOPHiS420 for all their hard work and testing to make it work)

Method 2:
First off in order for things to go smoothly you NEED to be on a rom that hasn't been deodexed yet. If you only rooted and installed CWM on your B09 rom then Skip to step 3 Otherwise Start on step 1

1. Download This Stock B09 rom and flash it (Credits: SuperR)
2. leave cwm on the phone This means when it asks you if you want to disable flashing of the stock recovery you choose yes!
3. Download the ota from your phone

3a. Go to settings > apps > all > Google Services Frameworks
3b. Clear data and Force Stop Google Services Framework
3c. Go to settings > system update > Update ZTE software
3d. Retry steps 3a - 3c until you get the update​

4. Before installing the ota use root explorer (or similar) and navigate to the /cache folder in the root of the phone, copy the obscenely long file named zip to your sd card root DO NOT MOVE OR DELETE THE ONE IN THE CACHE FOLDER leave the one in the cache folder
5. Reboot to cwm recovery
6. Do a factory reset (optional)
7. Install the obscenely long file named zip from your sd card let it do its thing and voila!

If you want to regain root and still have CWM installed then follow these steps:
1. Download Root zip - (Credits: chevanlol360) and place onto SD Card
2. Reboot to recovery
3. Flash the root zip

If you want to regain root and ended up with the stock recovery after updating:
1. Download This - (Credits: Junkie2100)
2. Download Root zip - (Credits: chevanlol360) and place onto SD Card
3. Flash CWM using the fastboot method NOT TERMINAL on Junkies tool
4. Reboot To recovery
5. Flash Root.zip

If you have trouble getting fastboot CWM method to work:
Read THIS and follow the directions in the first post! - (Credits: Junkie2100)

 

shouldnt be laggy. give it like 10 mins then reboot the phone should be good to go

 

It gives that date because you cleared the data for google services framework which held the last time it got checked. When you click on check now it should update the last time it check with your current time. If you dont get the ota right off repeat the steps to force update till you get it. Boston area should have the ota already tho

 

The tabs are scrollable , just slide your finger to the left on the tabs and you should see it

 

The saying "your doing it wrong" comes to mind lol j/k man idk why you arent getting it at this point the ota should of rolled out in all of boost's areas

*Edit* Try updating your PRL first and then repeat the force update method. Worth a shot

 

I had to repeat the force update method for a couple hours (not continusly of course) before it finally said i had an update

 

do steps 3a through 3d in the first post here and repeat every step until you get the update.
