DEXP VA170 ?
Another user on an Italian forum confirms (but not giving the exact source) it has the same firmware of DEXP VA170 which has similar but not the very same specs. The source could be on this Russian forum: On the DEXP download site it's not clear if the tablet firmware is catalogued among the smartphones https://ftp.dexp.club/Smartphones/VA170/
 * original post with picture, translated
 * original post with firmware, translated

because it's not found among the "Ursus" tablets https://ftp.dexp.club/Tablet_PC/

= See also = The user manual (below) reports the manufacturer as Well Honest Enterprises limited; the dealer seems to be a company called The China Office (https://www.the-china-office.com).

On its website there's a page for this tablet (https://www.the-china-office.com/ta8116-smart-tablet) containing almost no info.
