It wasn't branded when it broked, the guy who sold me this POS said it was working for 1 year cool after he flashed it in service point, it broked in my hand so i can't even be give it back to him.
Service nokia care said by mail that there is low chance its FW thing, they say it's much more possible it's hardware malfunction, like water, i does have some micro grey points just a side from sim socket plate. When i move sim it saying that device will reset now, so it is hardware, i wasn't sure before.
