    I loaded a custom firmware on a Note 4 Verizon with a locked bootloader. I may not understand this completely, but from what I gathered in the process

    ROOT
    Rooting gives superuser access and permissions, similar to superuser on Linux. You then have access to locked filesystems and the ability to change programs that were otherwise protected.
    *Note: rooting is usually necessary to first modify the bootloader and install a custom firmware.

    BOOTLOADER
    The bootloader is what allows you to install a custom firmware/OS. I think it's computer execution code that the phone defaults to when it starts up, similar to a bios on a computer. Most people that install their own firmware also modify the bootloader to include bios options, similar to a computer bios. TWRP is what I have for that.
    *Note: Verizon locks their bootloaders, so usually somebody has to find a software bug or hack to get passed the bootloader security.

    ADB
    This is used to interface, transfer files, and control your Android phone with a PC. I've seen people even mirror and control their phones on their computer with this to get advantages in certain games like PUBG Mobile.

    WHEN ROOTING and INSTALLING CUSTOM FIRMWARE
    You install the firmware through TWRP. You can backup the original OEM firmware through TWRP and you'll need to install one of the GAPPS packages if you want certain google services, such as Google Play for installing apps and such. GAPPS usually has to be installed with the firmware as well and not added later or it causes problems for some reason. You also might need to change code sometimes to get certain firmwares to install. For example, LineageOS would not install because the code that checks if the phone is compatible saw a false positive for being incompatible. So I deleted that code check and everything was fine after that.

    I couldn't tell you any more than that. I always follow guides and don't really know much about ADB or how all these rooting programs work exactly. I do suggest installing official firmwares though, since the unofficial tend to be broken sometimes or don't have the proper OS security activated. And this wasn't really an easy process; I think I spent about 4 hours of mild frustration trying to get everything working right. But I'd think any phone that doesn't have a locked bootloader would be easier. So good luck if you bother.

    What is your device? You mentioned LG, and Android 4.4.2, so I'm assuming it's older. But the ROMs and their support are very device specific. There's a bunch of custom ROMs out there. A while back I tossed CyanogenMOD on an old Nexus tablet since google stopped providing updates and the update it did provide severely killed the battery life.

    Now I just use the Pixel phones, since I don't have as much time now to tinker with gadgets. But if I had older devices I wanted to use more often I'd use definitely flash something onto it, at this point they're all super easy. If you've ever flashed a bios, dual-booted a computer OS, or flashed DD-WRT onto a router everything will make a ton of sense.

    CyanogenMOD doesn't exist anymore but it's been replaced by Lineage OS. It's one of the better ones.

    Here's a decent link that goes through 10 good ones:

    However from the ones I've personally tried:

    • Paranoid Android - by far the most stable, refined and complete ROM. Main problem is lack of updates, but if you're the type to set and forget this is a good one.
    • OmniROM - Lots of features and tweaks but not over the top. Generally pretty stable with consistent updates.
    • LineageOS - Pretty barebones, uses a ton of open source apps when it can, and has consistent updates.
    • Ressurection Remix- Crazy customizable but not the most stable. Very fun if you're into tinkering.

    Thanks. I'll check these out. I didn't realize about cyanogen; that was one I remembered from the last time I did research on this. The phone is a LG G3.
    I've been called a criminal, a terrorist, and a threat to the known universe. But everything you were told is a lie. The truth is, they've taken our freedom, our home, and our future. The time has come for all humanity to take a stand...
