The Teclast X98 Pro K9C6 is an excelent and price-worthy tablet.
However, the eMMC problems really needs to be fixed. It is not ok to sell it with a BIOS version that is known to cause problems that could brick the tablet in the end.
My tablet got the problem while installing World of Warcraft on a 128 Gb LD Official Flash Memory card (I bought it on AliExpress). The tablet died and would only boot to BIOS, where no drives were available, not even the internal. In this situation one is forced to try a complicated BIOS flash procedure that carries the risk of failing, leaving the tablet even without a BIOS, so called bricked. I went through all that and had to modify a flash programmer in order to repair my tablet. I could have sent it back for replacement, but then again I would run the same risk again, since it still comes with the BIOS version 1.05.
Now I have it up and running again, and I have BIOS version 1.13. Still, it sometimes looses contact with the 128 GB card, but that could be the card itself. Format is NTFS. I will try to obtain a Samsung card instead. I have removed Android in order to have more space for Windows 10. I have Android on my Samsung Galaxy Mega, and that is enough for me.
Anyway, I have just played a session of World of Warcraft on my Teclast X98 Pro, and it works pretty good for being played on a cheap tablet.
