I've also had some dead boards at recommended settings. I've been very careful and understand the risk. I wouldn't have bothered posting about it because I know their can be consequences. What the other poster stated was true, although it has been a small number in my situation. To be clear I'm not blaming or crying, I know what can happen the minute I flash a aftermarket firmware.
EDIT: I'm trying the firmware on S17 56T, S17 50T Pro, S17 53T Pro
So after you using a bunch of different firmwares on different units (judging by your previous posts) you just happened "not to cry" here as well as BlackPrapor and note that it is in same day and both of you are not even active on forum anymore.
Is it only me or is this fishy?
