[Verizon LG G3] roirraW "edor" ehT:
Hi! I too, came from the S3, albeit the Sprint version. I loved that phone, by the way. I think overall I was most satisfied on the S3 but the G3 definitely has some great specifications in comparison.

I can't comment regarding this. I've moved too many times in the past 6 years and had four different Android phones in that time.

Yes. The overall wisest way is to flash the 10B (KitKat) TOT using the .DLL that's extracted from the 35B (Lollipop 5.1.1) KDZ from a Windows PC, then use the Stump app to root it using the brute force method.

Google for:

XDA Stump

and then use TWRP Manager from the Play Store to install TWRP. Rooting gets more complicated after 10B and installing TWRP gets more complicated after 12B.

To flash a ROM - the order you flash things in matters if you end up dealing with JasmineROM 9.x or SkyDragon 6.x. After flashing either of those two ROMs, flash either the 24B or 35B Bootstack that you can find in [MENTION=2941286]xdabbeb[/MENTION] 's VS985 v2.0 ROM thread in the Development section. Depending on which Bootstack you flashed, if you flashed it before flashing either of those two ROMs, you'll brick your phone. Recoverable but no sense doing it if you can avoid it.

I recommend just getting used to flashing the appropriate Bootstack after flashing any ROM, that way you don't have to remember that with those two ROMs you can brick if you flash the Bootstack first. There's more details and exceptions but there's no use overloading you. If you always flash the Bootstack after, there's nothing else to worry about.

No. For what it's worth in my opinion, I don't bother fooling with non-stock Verizon LG ROMs any more. CyanogenMod/AOSP and ports of international stock ROMs often end up not working quite 100%, and you won't get all the features you will on stock. You can't use laser focus on CyanogenMod no matter what camera app you use, there are workarounds that at least used to work to get QuickRemote working on non-stock ROMs, but I haven't fooled with them in over a year so I have no idea if the same way works on newer ROMs.

I can get the most important to me features of non-stock ROMs by using Xposed and modules like G3TweaksBox.

All too often, after a user has flashed a handful of non-stock ROMs, sometimes they end up not being able to get Mobile Data working, even if they flash a stock rooted ROM. Only flashing the TOT or a KDZ will fix such a situation. TOT is recommended, it flashes more partitions than KDZs and can fix issues KDZs can't.

I can't really speak to this either. Every time I'm tempted to go Nexus the price and/or the no MicroSD card or lack of as good a camera etc sways me away. I'm going to keep my eye on the HTC 10 in half a year when I may be in the market again, but it won't be that cheap that soon.

Congratulations, you just absorbed 1 1/2 years of experience with LG devices that I got by reading nearly every post in nearly every thread in the G3 sections since that time, and flashing both my VS985s and my VK810 many dozens of times. ;)

P.S. If you go with the VS985, although I've been on [MENTION=2941286]xdabbeb[/MENTION] 's as pure stock while rooted 47A Marshmallow (although heavily debloated) for several months now, his custom ROM based on 35B is my overall favorite. You probably won't go wrong with either one of those, in my opinion.

Edit: By the way, it's a common enough occurence on the G3 that when flashing TOTs or KDZs, and maybe other situations, some people have gotten their IMEI wiped and have to go through some headache to put it back in, and you need to know what it was to begin with.

So if you flash back to 10B, root and install TWRP, the first thing you should back up in TWRP is "EFS" which includes your IMEI. Then save that somewhere like on Google Drive. It'll save you a lot of headache if you lose your IMEI. That said, I haven't lost mine once in several dozen flashes on my wife's and my G3s.
