How to recover from Bootloop "mismatch_sig_len"?

[AC Question]

I am stuck in a bootloop "mismatch_sig_len" with my LG V10 on T-Mobile and I have tried putting it into download mode, factory reset and a couple of recovery tools that can't find my device. I have read something about having to "short" two pins with tweezers or copper, to get out of this. Are there any successful methods anyone knows of? Thanks in advance

Only method I have seen to get out of bootloop is to send it to LG for repair.
