User Debug Mode?

---

I just got my Optimus 4x HD today (off of craigslist, I am in the USA) and I noticed that the homescreen says "User Debug Mode" in red right above the home dock (where the messaging, phone, and contacts are). Does anyone know what this means? I am on AT&T and everything is working. I will try to post a picture soon.

EDIT:
This should probably be in Q/A, sorry if this is the wrong forum!

He said he got it from Mobile World Congress or something and it was a tester phone.

From the looks of it its a developer phone. Is it already rooted?

Mobile world congress? Never heard of that so I Google it and its like a convention of all the OEM and network providers showing off their new product. So you are really lucky to have it...and I hate you :)

if you goto market and download a terminal app, and you open it and login on your mobile. do you see if the prompt is "#" or "$" and does su - work?

do you know how to use adb? can you connect from a pc to it?

It says /system/bin/sh: su-: not found

However, I can get into root explorer and go to the root directory. All of the other root apps say that I don't have the right permissions (like root checker, titanium backup, etc). I do know how to use ADB as well. I tried the rooting method that the one guy used on the development thread and that did not work. Also in the secret menu, the bootloader said unknown just like everyone elses.

I do know how to get into ADB on my computer and have the right drivers, but I don't know what you would want me to do.

EDIT:
Does anyone know how to take a screenshot natively?

Have you tried to push su directly?

I actually just rooted and used screenshot ER to screenshot before I saw that method. Thanks! The root method in development worked, I tried again and second time was the charm
