LG K7 Error 1003 Bootloop MODIFIED

[Moonixia]

Hello there! Today I was messing around with some root apps and ended up with this Bootloop error. My USB Driver doesn't seem to be connecting to my phone and I'm starting to get extremely worried. I'll keep looking for ways to get the driver going, but for now I'd like to put this up here in hopes that someone can give me any sort of help whatsoever. I'm admittedly very new to rooting and I'm pretty clueless about these sorts of things. Any help at all is appreciated, thank you very much!
EDIT: Forgot to mention that it's an MS330 if that helps any!

1. "Modified" means it's rooted (or, at least, partially rooted).

2. Try holding the power button in until the phone vibrates (maybe 30 seconds). If it does, the PC should recognize it again.

3. To root, see https://www.getdroidtips.com/root-and-install-twrp-recovery-on-lg-k7/ (Unless it's on Marshmallow or above, in which case I'd flash Magisk instead of SuperSU.)

Ironically enough I was trying to download Magisk and that's what caused the bootloop in the first place. Now I'm assuming that it might've had something to do with the fact that I had SuperSU already installed. Didn't do enough research to figure out whether or not they conflicted.

yes magisk and super su don't play nicely. need to remove super su for magisk
