I made 100% sure to update my SU and my binaries prior to updating, as I was trying to avoid repeating my mistake from the last leak(on the first leak, I screwed up and had to redo it). The only thing I did differently is that I temp unrooted the second time....I promise you your failure is not due to failing to temp unroot as I've never temp unrooted a RAZR (original or HD) and it hasn't caused me to fail a root restore. Not updating binaries or having a improper version of SU apk installed has though. The biggest reason I've seen failures is if you've rooted your phone but not gone into the SU apk and given it permission to use root itself before backing up your root it'll fail. This usually happens to those of us who are quickly going through and restoring to factory and rooting to get back to whence we came for whatever reason.
Well, it may have been a fluke, I don't know...obviously you know better than I, but if you ask me, it doesn't hurt to do the unroot, just to be safe, seeing as it only takes half a second.
