It looks like you borked the system folder when you made your changes. That's why it's better to use a decompiler like apkmanager instead of just using an archive manager like 7zip. I believe you can do it with just 7zip, but be sure you have everything set to "store" and you don't attempt to sign the frameworks-res.apk or the systemui.apk, you don't resign system files.
If you do post something like this, please post it as a themed BACKside-IHO like the ICS themed version was at xda. Once you make significant changes to the workings of the ROM, or build from IHO source with whatever changes you like, then you can post your work as
your ROM.
Of course, you can always build from IHO source and post your own ROM as pure IHO as well!
And there's still a need for an AOSP port, I'm sure a lot of people would love to see one for the OV!
