I was right. I unrooted, tried to install the update, but it just error'd 'out, and would not install. I have been on Android 2.2 for years, and just recently upgraded my phone, so this new version of Android, as well as having a new phone is putting me all the way back to the beginning of learning it all over again.
Anyway, the ZV5 update wont install, and I am pretty much guessing this is do to my internal-Rom files being different.
Oviously system files were changed, so the update will not install. I learned this from "googling" about the phone, and I am quickly figuring out that there is not a whole-bunch of info relating to the LG Volt 2, (LGLS751).
Also, I am learning that in order for us to have a custom-recovery on this phone, we need to "unlock" the Bootloader. And from what I have read, this is not so easily done when it comes to LG phones, even when it comes to rooting LG phones, or I guess the newer Android versions, Lollipop etc., it's the same story, not so easy, for whatever reason.
Unfortunately for me, before I rooted the phone and started messing around, I did-not make any kind of a backup/nandroid thing at all. So things were changed, and my stock rom is no longer a stock rom. And looking around on various sites, no one has yet to do anything with this phone, as of yet. I will have to revert back to stock, and then I can install the update. But I cant do that as of yet, because I have no custom-recovery, or the stock rom itself. Looking around I am pretty sure you can get the source code and rom's right from LG's developer site, but I can't do anything with it myself. So until someone does, I am stuck where I am for now.
But then again, at least I was able to Root the phone, I tried various methods, and Kingroot was the only one that would work with this phone in the end. I succesfully got rid of Kingroot and replaced it all, as I explained here:
http://androidforums.com/threads/root-lg-volt-2-no-computer.935445/ , so I am happy about that, and if that is all I can do with this phone for now, then so be it I guess. I can get that far, but I am not a developer or a custom-rom maker either, I just dont have the know-how to do it.
I will get the zv5 update to you like you asked, it's 7:00 pm est, just give me a few hours and I will post the link for you.
By the way, if you don't know, if your phone has auto-downloaded the update, you should, just as I did, get the zipped file yourself. Mine was located in the Phone's internal card/memory, in a folder called "cache". I am pretty sure that is where I found it. I know for a fact it was in the cache folder, (still is), and that folder is either like I said above, on the internal memory partition, or it was in the root section of the phone. I don't remember, but anyway, if you look on your phone you should find it.
Is there anything cool you plan on doing with the update in question?
Anything that I/we/anyone else can do with it after you get your hands on it?
