everything should be fine with you, the older younger version is determined by the bootloader, it seems to me that there are almost no changes in the difference between the versions, the difference is not significant at all, it seems like a different display and something else, I haven't seen the insides of the older version yet, but soon someone will post a review and it will be clear. this opinion about the differences may be wrong.
Hi Richard,
?
I just purchased the 406 from R&L arrived today. Mine has the same marking. My confusion is that the upper right under Zeenko is ZS-405, but S/N is SU-406-xxxx H/WV0.4.6. So did "they" forget to update the upper right?
?
