Anyone else having a big when you try and upload non-text media? SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

I need a mass effect 3 rip that isn't legendary edition. I've tried FitGirl, but theirs seems to be broken.

Basically the title. I have a Samsung S9+ that i want to root, but the OEM unlock feature isn't in developer options. It's north American and has a Qualcomm snapdragon cpu. Any workarounds?
