Confirmed, just re-rooted again tonight. I've been de-rooted twice now, once from a 10.2.5 update and then again from a 10.2.6 update (even with renaming otacerts.zip). Are there any other methods that can be used to disable the OTA updates? I really don't want to go through this setup again.
Also for anyone having errors, really, the only thing you can do is just run it over and over, i ran bin4ry's root so many times I lost count until it eventually worked, qemu root is good too.
