Exclamation [Q] How to root without wiping?

Im looking to root but without wiping my One S and I cant seem to get it. Towel Root doesn't work and neither does framaroot. Toolkit programs to do it via PC end up requiring bootloader unlock which will wipe the phone, but I simply just want to root. Htc QuickRoot tool says my phone is patched so that much im aware of. Im just wondering if any other methods have been introduced to help with this. Thanks.
