LG G2 stuck in bootloop, pc won't recognize it? - G2 Q&A, Help & Troubleshooting

I'm trying to find the IMEI of an LGG2. It's a Rogers phone and the IMEI isn't on the back, sim tray or anywhere on the physical phone. The phone is stuck in a boot loop so I can't go into the settings to retrieve the IMEI, so I'm trying to fix the boot loop issue. When I go into system recovery and wipe data, factory reset, or wipe cache I get error messages:
E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/last_install
E:Can't open /cache/recovery/last_install
E:Can't open /dev/block/platform/msm_sdcc. 1/by-name/misc (No such file or directory)
E: failed to mount /cache (No such file or directory)
I'm trying to flash it using my PC but the PC isn't recognizing the device. Is there anyway to flash it or unlock the bootloader without the phone turning on? Alternatively is there a way to force the PC to recognize the phone? I've installed drivers for it but it's not showing up in my device manager at all.
Basically how do I get this phone to turn on? I'm not sure the history on it as it was passed down to me, but the person said it had never been rooted and the bootloader is for sure still locked. Help!
