Hi Leo!
Thanks for your response.
Where have downloaded the update? Because from “TeclastOTA” icon I can not do the online upgrade, say “Check failed. Please check your network”.
UPDATE NOVEMBER say? But if this tablet went on sale recently in January 2016. We are talking about the same? Teclast X98 Dual Plus (Android 5.1 + Win 10).
Thank you so much for help me.
