I'm creating this thread to regroup all that I know about the LG G Stylo H636, Fido carrier. I'm doing this because I could not achieve root on this device.

I have been able to get into download mode, using the Send_Command.exe file. I was able to dump the system and recovery partitions (5.0.2). Both are available here: https://mega.nz/#F!HFgTQSzI!NHBjp2bpqVL6T9fByMJQ0g

Here are the mounts:
