Nuvon

I'll try to contact with GB and try to replace for new one . Anyway thank you so much for information and your help

Ok thanks for it , will I loose my warranty?

Ok but I dont know how to pull of cover

Ok , thank you , but if I can get multimeter what i need to do ?

I bought this mod on Gearbest and it came to me ( Ukraine) from Netherland and i'll try to contact the seller

No , i dont have it

Yeah , but i didn't got my warranty card , it came with out it

Today i got my smy sdna 200 and when I turn on device it showed me "warranty service" and after ~4.5 hours charging it shows "Check battery" p.s I tried to perform usb recovery charging , but it doesn't help me
