Guys after many hours I have managed to solve my issue:
if portals are not visible.
do the below (in my case MODE 3 worked):
Three emergency boot modes are supported. They are signaled by means of LED indication:
Mode 1 (LED white, slow blinking). Selecting alternative NAND - if for some reason download or update of the software from the current memory bank has not been successful, this mode switches the loading from the alternative flash memory bank;
Mode 2 (LED white, quick blinking). Reset to factory settings - if some STB settings do not allow to boot, you may need to reset the environment variables of the STB software to initial value;
Mode 3 (LED white, lights constantly). Emergency startup - loading the System Recovery Utility menu via USB or over the network (requesting update data via DHCP protocol) - in some cases, if you can not boot from modes 1-2, this mode is used.
