I have been s-off since the downgrade was discovered so I don't know about smartflash but I do use 4ext. And I feel like I'm intruding on wloftus because he has you dilemma figured out, but here's what I'd do. Sorry wloftus.
Fastboot boot "anyrecovery.img" and flash the phone Rom update. You can flash 4ext, cwm or twrp. It doesn't matter that 4ext is installed on the phone, it won't hurt if you boot a different recovery from fastboot. 4ext will still be there when you regular boot to recovery. I've done this many times with twrp installed and fastbooted to cwm.
Edit... You said you reinstalled meanrom, if you had a custom kernel installed to it when u set up phone Rom then the update.zip might not get you back to meanrom. If you had the stock kernel for meanrom then the update should work.
