Was the roam only option there? If so when you select it the little circle icon stays empty but it is on.
Wish I'd taken a screenshot. The menu selector that says "roaming - select the CDMA roaming mode" was grayed out. There was no option popup.

After restoring nandroid it was back to normal.

Something odd I just noticed though is today it was inaccessible again, I had to go and select mode of operation in order for it to ungray, so something else may be afoot... will re-flash and see if the problem goes away after selecting a network mode.

So upon flashing it again, I saw the roam only option and was able to select it although it did fail to connect afterward, I'll just assume that's PRL-related.

Do you happen to know what frequency you are on?

I'm sure you can connect to 1900MHz just fine (since that's what the M7 uses). More curious if you could connect to 2600MHz or 800MHz. I think you can check your frequency with Signal Check Lite: https://play.google.com/store/apps/details?id=com.blueline.signalchecklite
That's an interesting point you bring up. I haven't gotten any data errors or missed calls since changing my PRL. I do use Signal Check Pro and as far as I know there is no LTE on 800 or 2600 here. I wonder if Sprint added Spark sites to the PRL that comes on our phone that don't actually exist and that is causing the errors people are getting. I really don't know a ton about PRL's but that's just a thought since my issues seemed to go away after switching to the corporate PRL.

They both worked for me on the stock odex rom. I had to get rid of epst.odex and phone.odex and wipe dalvik but they work.

If the phone apk was based on the M8 phone apk originally it should still work with Spark, but I don't have any way to test it since I've only seen 1900 LTE in my area.

Just to clarify, I was worried about the PRL file itself not being fully Spark compatible not the phone apk.

I can confirm this works on ViperOne for anyone who is wondering. I had heard things about this rom using the dialer from the international version and EPST not working with it because of that, but it does work. I'm on 1.6.0.
Edit: both work

I'm one of the many people out there having trouble getting any reliable data with this new spark network so for those of you who have swapped prl's how well has your data been and which have you been running as I'm very disappointed with my service thanks in advance.
