Nexus 7 won't restore from TWRP backup

[crank_girl]

Hi, having a few probs after installing 4.3 update on my nexus 7. It was really laggy and horrible so I decided to revert back to CM. Of course, I had to re-root and reflash TWRP. I can get into TWRP fine but when I try to restore it either fails or just hangs. Any suggestions as to what I can do to fix it? You can probably tell from this post I don't have much android knowledge, I'm just very good at hunting out and following instructions.

I'm not averse to reflashing a rom and starting over though I'd prefer to restore if possible.

Thanks.

I'm going to guess your running into the file structure problem. When switching from Android 4.1.x to 4.2.x there was a known " file structure " change in Android. This making "downgrading" back near impossible using your Nandroid backups because it won't redo the file structure and partitions. I believe this has also changed again with 4.3, some slight changes that are affecting downgrading.

Thanks for the reply. I deduced as much after finding nothing much on the net about this problem. So I restored the factory image and started over.
