Thanks, I will download the files you gave me links.
My HI10 ((Hi10 Q64G42151200377 W10 only) is running Bios C106_B101UAN.607.
Is the linked bios a more recent version than 607 ? (if it's not, I suppose there is no interest to reflash it as there is no update).
Last but not least: Can this tablet (srial above) be transformed into a double boot Android+W10 or is it impossible ? If it can, any link to a thread about it ?
Thanks in advance for your reply and best regards!
