Flash a custom ROM that's already rooted.

my bootloader is locked

Ok, I gotcha. Your wanting to keep your warranty and not use the unlocker tool. I don't blame you. Mine came with JB so I didn't have that option and I'm unfamiliar with the way around using the unlocker. I'm sure someone who's gone through the process will come along and help you out. GL

This is what you call a half root. You can access root via adb but apps can't access root. I resolved this by unlocking and flashing su and superuser into /system

I know that's not what you want to do but you may not have a choice.

how do you backup ota rootkeeper files so that you can reroot after a system restore?

As you can see by the screenshot, su which is the root binary is still there. It's the factory reset which broke the link between apps and root. Ota won't stop that. Those that originally installed superuser into /system shouldn't be affected by factory resets. Those that installed it into /data which is the normal app install method, were impacted if a factory reset was done. I do speak from actually experiencing this, exact same thing.

I'm going to assume, can't do much more than that, that he rooted on ICS with the debugfs method, installed superuser apk via market or side load which put in /data, upgraded to jb, restored his su and still had root until he did a factory reset which wiped superuser, not the su binary itself, which broke the root link to apps. That is why voodoo says the su binary is there, but there is no root permissions.

Now he can most likely connect to a PC, type adb shell, and at the prompt type su. That gives a # prompt which is root, so I call that half root because standard apps can't access su.

Why don't you try the steps mentioned in this thread?
I got out of similar situation following instructions in other thread (but not factory reset). Might work, worth a try.
Good Luck.
