So last week I accidentally screwed up my S5 by deleting the "google play store" app after successfully rooting. I did not realize that so many "other" apps rely on that. I used Kies to get back to a factory reset state (as I forgot to do a NANROID backup). So I am happy for that but I now can not re-root my phone as it keeps failing. My question is am I only able to root once ?
