Reset many times (and also earlier too), all possible combinations: with / without sim, Wifi LED on / not on, right after power up, holding reset for up to 1.5 minutes.
lan LED flashes at 3 different speeds **while reset button is pressed **then off, which usually confirms the reset has completed, but not reset.
LEDs do not flash in pattern after I release reset.
Mifi does not reboot after I press reset.
Even the new name of wifi has not been reset to GL-MIFI-777, its still what I changed it to. Also called service provider who changed sim from data sim back to a normal phone sim, then back to data sim (thinking something was in cache stuck on their side).
Mifi not reset at all, the default password does log me in, only the password that I set logs me in.
So mifi does not reset.
All this happened after I changed sim to require a pin (<<== my bad), so is there a correlation?
