(Device should be connected via USB cable to PC, LAN cable should not be connected)
Press and hold WPS + Power buttons on top of the router
Hold buttons pressed until red light indicator turns on
After it goes off, release fingers from WPS and Power buttons. Shortly after (10-20 seconds) blue light indicator will turn on and remain for half a minute or more
When it goes off you should see green light indicator - this means device is in download mode and ready for detect/unlock. If it doesn't check method 2
METHOD 2
(Device should be connected via USB and LAN cables to PC)
Launch Multiupgrade tool. Select Network card to which your router is connected to
Select B593-22 file and click 'Open'
Press Start
Blue indicator light will start glowing, if indicator does not glow with blue color you will need to restart the device and repeat the process
After a while indicator will turn into red, press 'Stop' button on upgrade tool, disconnect LAN cable from PC
Now Press and hold WPS + Power buttons until red light goes off then release fingers from buttons, shortly after indicator will turn into green color, which means it's ready for detect/unlock. If device did not remain with green light turned on (or didn't turn with such color at all) then press and hold WPS + Power buttons until red light goes on and off, then release fingers from buttons and wait for blue indicator light and shortly after it goes off green light appears
Before detection and unlocking of router check device manager if it is installed correctly. Router should be visible under Modems and Ports sections, only then proceed further. If it isn't visible under mentioned sections drivers might be missing. To have drivers Download and install Mobile Partner software.
