android not working after build.prop update

[phidani]

I might have missed a conversation about this already, but I just update the build.prop. Afterwards, I pushed it back onto the nookcolor (running Honeycomb), the rebooted. Now, when I turn it on the android system does not boot. I am stuck with ANDROID in the bottom left hand corner. Ieven tired to push the original back onto the device, then still the same result.
Any ideas?

so an update to this issue, I just redid the whole root. I first installed GApps2, then reboot. Next I pushed the LiveWallpapersPicker app, and then rebooted. Now it is stuck in a similar non started up phase as before. Any suggestions.
I followed:NookColor Enable Live Wallpapers - nookDevs
