I would suggest holding off on ROM Manager till next week, when hopefully we will have offical Optimus V support. I have had two corrupt downloads via ROM Manager, one wasn't even recognized by 7-zip as a zip file.
I downloaded the 6/1 build from a link posted in the thread over at xda, grabbed the framework and systemui apks, cooked my theme at UOT, rebooted into recovery, backup, wiped cache/dalvik-cache, flashed ROM then gapps then UOT theme, rebooted, no issues.
Only bug I've found so far it camera won't autofocus, which keeps barcode scanners from functioning properly (though QR codes seem to work).
