my y580y from smartbro (philippines) cant connect to the GUI or dashboard using the original pw "smartbro". nor does "admin". neither work. what happened was i tried to tinker with the backup.bin file that i downloaded and reuploaded. when i uploaded the modified bin file it gave me an error saying something like upload failed. but then i noticed that the wifi signal was gone. so i restarted the device... same thing.. so i pressed the reset button for like 15sec.. it rebooted.
everything seem okay as the wifi signal is back. but when i tried to connect to 192.168.1.1 and login the passwords doesn't work anymore.. i flashed the official firmware, same thing.. i noticed that flashing only took a second or two.. is there any fix to this?

I can't access the web gui because the mifi itself does not connect from my pc, drivers already installed, but somehow it can't connect to browser, i can't enter a default gateway

can any one give us a deafult wifi key so that it can access to android device or ios.
