Un Root gone wrong ... please help

[lvnyc]

Last month I rooted my vzn gs3 to run the liquid smooth version of jelly bean, all was well there. Now today, because I recently sold my mac, I looked on youtube to see if there were ways to un-root without using a computer..surely I found a few videos..anyway I looked at one and followed all the steps using mobile odin. Initially all went well, I was back at ics and ready to download vzn stock jelly bean..but now when I download it, it says 4.1.1 In my settings but my phone is still running ics .. the ui, homescreen, menu. .everything is still ics, with one or two features from jelly bean..not sure how this happend...is there anyway to fix this? Thank you
