I installed the firmware Lenovo_A6000-l-TH_PH_USR_S008_1503172030_Q113507.1_BMAIN_8G_ROW.
Communication has settled but it also lacks the Russian language. (More locale does not translate all the items).
If this firmware takes an on-hlos.bin file and adds to another firmware, the network will work? Is he alone responsible for the network settings?
