Has anyone tried this? I know it sounds counterintuitive but... has anyone tried this yet... I'd luv to know what the possibilities are. I'm plannin on purchasin a n810 later this month

If anyone has any spare time and could try it... let me know how it goes plz

ok, well i'm a noob, but i think that if you take a 2007 backup you can do it. because if i'm not mistaken, please correct me if i am, you can reset a n800 that way if the upgrade didnt work out well, so i think that if would work.

As I said in your other thread, this doesn't strike me as a good idea.

But if someone really wants to try, I think the first problem will be that the Flasher will see the OS2007 firmware image is written for RX-34 (N800) hardware and the N810 hardware identifies as RX-44. Flasher won't let the install proceed.... for your own protection.

Probably the only way to get it on there will be using a method similar to the way OS2008 was installed on the N800:

In theory it should work with some limitations. It would need running older 2.6.18 kernel (= back to 330Mhz) and the kernel may need some tweaks to boot (i.e backport 810 board configuration sources). Also initfs may need some changes, battery charging daemon (bme) is different for n800 an n810 (perhaps due to different battery used).

Also there is one major issue - both older kernel and OS2007 does not support builtin keyboard (and other extra HW like GPS or light sensor). Backporting kernel driver should be relatively easy but disabling/enabling on-screen keyboard when HW keyboard is opened or closed may be a bit tricky to do in OS2007.

I think I'll try it when I get 810 but it may not be very usable for normal users who expect all builtin HW to work smoothly.

Also another way is to tweak OS2007 to live with newer kernel which will solve dual booting issues with N800 too. Unfortunately some parts of wi-fi connection manager stuff is closed and currently WLAN connections do not work with newer kernel.
