Are you able to boot into Recovery and wipe the cache? https://www.androidpit.com/how-to-clear-the-cache-on-the-nexus-5x
Is there anything I can do plus my warranty expired.
You can still try contacting LG. They are very aware of this problem and have replaced/repaired some outside of warranty.
I Have the same bootloop problem. What should I do? factory reset didn't help.
