If the web interface is inaccessible or you are updating from a very old version, use the USB recovery method.

Steps:

Copy the firmware file (rename it to UPDATE.BIN if not already) to the root of the USB.
Power off the B880-70v.
Insert the USB stick into the router’s USB port.
Press and hold the WPS button (or Reset button depending on version) while powering on the router.
Keep holding for 10-15 seconds until the Power LED starts blinking rapidly.

Wait 5-10 minutes. When all LEDs return to normal, remove the USB and reboot.

Rollback / Recovery

If router behaves incorrectly, try factory reset (hold reset button ~10 seconds) then reconfigure.
Some models let you re-upload an older firmware via GUI/USB. Only use firmware intended for the exact model and region.
If the router is unresponsive after a failed update, check recovery/TFTP procedures from official support or contact your ISP/manufacturer for RMA/replacement.
