I'm going to say this once, so please don't ask later...

IF you don't care about being able to use the GPS with any 3rd party apps, then you can disregard this post and flash away.

IF you DO care about being able to use the GPS with any 3rd party apps, do NOT flash this update.

As you all know, the PRI completely locks down access to all 3rd party apps trying to use the GPS. What you don't know is that even by flashing back to stock completely and rolling back the PRI to 1.35_002, then updating back to a custom rom/radio, the PRI comes back.

I'm not sure why or how it happens so please don't ask, but if you flash this update, and then think you'll be fine by rolling back the PRI, please take this as a warning.

The ONLY way to roll back to PRI 1.35_002 and KEEP it while still using a custom rom/radio is:

1. Flash back to stock, let customizations run to roll back the PRI.
2. Update SPL to 2.40 via USB. DO NOT USE SPL 2.47 IT WILL NOT WORK.
3. Flash either the 3.35 or 3.56 Sprint Update and do NOT let Sprint customizations run at first boot (THIS STEP IS REQUIRED TO MAINTAIN THE PRI)
4. Now you can flash your custom rom/radio of your choice and the PRI should read 1.35_002.

There's more.

I didn't label this thread PRI from hell for no reason. After you've successfully rolled back the PRI to 1.35_002, your DMU keys will be corrupt causing you to be without data. There are only 3 ways to fix this:

1. If you have an old handset (non pda/smartphone), log in to your VZW account online and activate it. This will prompt you to remove the data feature codes from your plan. Once complete, reactivate the xv6800 and add back the data feature codes you removed. Wait 2 minutes and dial *22899. If it says you need to be authenticated first, you may need to call customer service and have them authenticate you. Then dial *22899 again.

2. If you don't have an old handset to activate, you need to call customer service and get them to perform a DMU reset on your device. Also have them remove all data feature codes from your account and add them back on.

3. Swap out your phone.

If you care about being able to use 3rd party apps with the GPS, DO NOT let the PRI update as you WILL regret it.
