Restore a new UI backup on an old UI firmware

Hi guys,
tired of the new ui firmwares I want to came back to the old ui official firmware but I dont have an old backup, I just have a new ui backup.
Is it possibile to restore a new ui backup on a old ui firmware? maybe using on of the firsts new ui firmwares?

thanks

uff, that´s agood question...I seriously doubt that!
But if it´s just about your contacts, you could sync with outlook first and then sync with old UI.

well I want also sms and calendar back... and after all I dont have a m$ Os, so I cant do a sync.

Ok... I'll wait for a good beta firmware

What do you use Apple´s OS `?, Ubuntu,...ask here in the forum, you are for sure not the only one, who is not using Windows OS. At least you could sync calendar and contacts!

I use osx and archlinux.
The phone is not seen as a good sync device so with osx I cant sync nothing.
Never tried a usb sync with linux.

You should ask evow04, I think he knows a lot about this....

Seen some app on the chinese bbs which can convert new ui backups to old ones if I'm not mistaken...but you'll have to dig through the forum because I don't have the link.

thank you n2k_u, I'll do it if it doesnt need a chinese language knowledge
