Hello!

I rooted my phone a few months ago and it worked fine. I tried again yesterday (using sql editor) and keep being told that I have been denied superuser permissions. Does anyone know how to fix this??
I uninstalled and reinstalled my superuser, and tried the su superuser fixer download.

The superuser fixer says: Gaining root access: FAIL!!!

So I downloaded Root checker to verify that I am in fact rooted, It says: Root Checker has been denied Superuser permissions

I then downloaded SU Checker and it says: STATUS: su declined/not found? Denied superuser permissions

AAAAGGGHHHH!!!!!!!
I don't know what to do from here?!
Can someone please tell me what I need to do to get superuser to grant permissions?!!!

 

I haven't done anything differnet?
My phone did have an update not too long ago, not sure if that had anything to do with it?
My ROM is not custom, its whatever my phone came with.
To be honest I don't even know what the .621 update is, or how i would get it.
Which I know prob sounds silly, and most would say I shouldnt be rooting my phone if I dont know what those things means. But I only rooted my phone to make a change with a game i was playing, I was trying to do it again and now can't?

 

Yep, it says version 4.5.621

Does this mean I'm outta luck!?
