[Q] TWRP Bootloop "DESPERATE" topic

Friend's phone. Trying to fix for them while they are in hospital. Phone is stuck in Boot loop back to TWRP. I've tried the "Fix Stuck IN Custom Recovery"...no go. I tried the KDZ back to stock, keeps losing connection to server. Tried the TOT method, no matter what Megalock I use I keep getting the "parallel lock key" message. Very, very perplexing and frustrating.

PLEASE HELP!!!:eek::eek:
