Hello Friends,
I´m new in the forum, i read all post but anything help me.
I have a Teclast X80 Power (B2N3) Dual OS with bios 3.03.
The internal microSD Card slot, not run correctly, only run on USB OTG Adapter, I need one solution for repair this bug. In other forum the people comment that this resolved upgrade the bios from Windows, but this solution not run in my case. Windows tells me that the current version is correct and the bios options are fine.
I sincerely want to solve this problem only to sell it … I’m very disappointed with the product, little RAM, ROM Little, Bad Wifi.
Regards
