Download & Installation (assuming, you've unlocked the bootloader following Korelev's instructions)
1) Download and open the Official TWRP App from the Play Store
2) Select TWRP flash
3) "Select device" > "LG Spirit LTE (H440N) -- c70n" > select the latest image available
4) When the image is downloaded, return to the app and "select a file to flash". Select the downloaded image and tap "Flash to recovery"
5) Reboot to recovery
You're in TWRP!
NOTE: To boot into recovery with hardware buttons use this method. Power off the device > press and hold Power + Volume Down buttons simultaneously > keep pressing them until the LG logo shows up > when the LG logo shows up, let go of the buttons for 1 second and then press them again. A factory reset menu will show up. Select "Yes" two times to "wipe" your device. Don't worry, this will actually NOT wipe your device. It will boot into recovery normally. This is because LG phones are a bit different and they instruct the recovery (TWRP in this case) to automatically perform a factory reset of the phone by triggering the /misc wipe flag. I mapped /misc partition to a different partition (/pad) so TWRP doesn't perform a factory reset.

Some features were untested, but the most important ones seem to work just fine. As I'm pretty unexperienced with this, help from other devs would be greatly appreciated. If you come up with an improved version of my build, let me know and I'll edit the OP ASAP.
