[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] bladebarrier:
I swapped from the original 10.1, to the 2014 10.1 P605-V, Verizon stamped edition.

I have a few questions after spending a good bit of time reading up and looking for some clarification.

I started on 4.4.2 and with no SIM in, could not OTA. I'm not shocked. I downloaded the 5.1.1 USA Verizon ROM from sammobile, and was able to flash it with Odin, with no issues. <-- Not a question, just letting you know where I'm starting from to reduce confusion

I can't find any way to root the Verizon model. I tried using the regular 605 root in XDA forums, from chainfire, and Odin gives it a fail. I'm guessing there isn't a root for the 605V, at least on 5.1.1, based on the posts of others here. I also tried GeoHot's root, and the device removes it before it can even try to root. I gave full permissions, but it gets deleted during the install process anyways. Can anyone confirm that is the case?

It appears the bootloader is locked, and I'm fine with the fact that I might not be able to unlock it, but I just wanted confirmation.

I downloaded a paid unlock carrier option (not bootloader unlock), and it says that it's compatible with this model, however it comes back with saying I need to be rooted, which leaves me in the dark as to if you can swap to a carrier like StraightTalk. Verizon told me there's no need to unlock this tablet, and it can be swapped to StraightTalk without doing anything. StraightTalk confirmed this on the phone. I'm ok with staying on Verizon anyways, but was looking for confirmation that this is the case, and the Verizon branded tablet (fully paid for) is capable of using other US carriers that are using the CDMA Verizon network (the Verizon model appears to have a secondary modem that allows it to talk on the US bands, whereas the international 605 does not appear to have that option).

If I'm unable to root, and on a locked bootloader, is there a way for me to use google phone apps on the CDMA network? I see that Verizon has a service that allows you to do so, sort of, but it sounds like it works in a way similar to how google voice used to work. It also appears to require your phone to be on Verizon (my Note 3 is on ATT). Can I get the AOSP dialer running on a tablet, and use it as a phone/message device, with the phone number that comes with a 4G SIM card? Verizon seemed to think I could text no problem, but I didn't discuss rooting, sideloading, or anything of that nature, regarding calling on the actual network (ie not through wifi or cellular data)? I've read that the international version can make calls on the standard network, but I got the impression that people doing so are using cyanogen or aosp, etc, so based on the bootloader/root questions I posted above, I'm a little unsure if there's a way for me to use an aosp dialer on the tablet while it's running on samsung/verizon software. I'm concerned about trying to drop gapps for cyanogenmod on it, especially since I do not have a custom recovery. Any idea if I can run the "phone/dialer" app safely, or an alternative, where it would use the actual cellular network instead of purely being data based?

Can I revert back to a previous stock ROM (4.4.2) and obtain, and continue to keep, root, without serious risk?

I'm plenty happy with the tablet as-is, and very happy that it has a secondary modem for the US CDMA Verizon network, as well as international bands, but I'm a tweaker and would really like to do a bit of de-bloating and customization that it sounds like are tricky with this particular variation.

Thank you for your time in reading my long post.
