Hi, I've tried following multiple TFTP unbricking tutorials but I simply cannot get my router to enter safemode. After a few seconds of it being turned on the Cog lights up when the Padlock is supposed to and it doesn't request any files from my TFTP server. I've tried multiple tutorials but they all say roughly the same.

(Note: Sorry for kinda clickbait on model I couldn't find 740N....)
