I bought a baikal miner to asicminermarket.com some weeks ago and I was a bit scammed (yes, avoid those guys and buy only to the original seller, that was my fault

Has someone of you have found a different update way through the orange pi or similar to update the toy? Or have any of you had the same problem and has found a different solution? Probable cause is the USB port problem but I'm not 100% sure about it.
Thanks and salute.
EDIT:
I have recieved this in my email this morning. It's funny, I haven't recieved any real support from asicminermarket (forget about the money devolution if not satisfied they say in their web), but seems they have more probably defective Baikal to sell. See that seems that the discount is the same you buy one, four or more baikal... I love the Dear at the beggining of the message. AH, you are totslly allowed to use my coupon if works, I will not buy anything more there never, but proceed at your own risk...
