    Hello, I have an lg stylo 4 straight talk phone with an OEM unlock feature in developer options. I’m wondering if this makes it possible to unlock bootloader and root with this method since it is now late April of 2019. I’d really like to root my phone without doing harm. I’m new to all this information on how to go about all this, but I’ve been doing my research and Ann trying to figure things out and clarify unknown terms and such. Could anyone please help?

        I just posted a reply to Candace that explains the answer to your question.

      Jason Nichols says:

      As of yet, no. The OEM Unlock is only the first step in unlocking the bootloader. To complete the process, you need the unlock.bin file from LG. Since the Stylo 4 is not on the list of devices LG will unlock, they refuse to issue unlock.bin files for this phone. It REALLY sucks because there are many things I would like to do with this beast of a phone but that require root.
