[INFO] The Amazing Secret *cough* Codes!

[snap-your-toes]

Ever since I had my first cell phone (one of those fancy little bricks by Motorola) I've loved finding ways to "mess around" with the software and hardware. Now that I'm a little bit older, and a little more experienced, I love to manipulate coffee to do exactly what I want.

But who ever said that you couldn't go back to where it all started?!

I scoped out almost all of the manifest files on my LG-H810 last night and was actually disappointed. Either its because I'm not root (no working computer at the moment), or AT&T are just big a-holes. There's barely any "secret Codes" still intact! But I dug deep and have been able to bring you....

Secret Codes of the AT&T LG G4

*#06# - Your typical IMEI code
*#*#244773825625#*#* - Version Info
*#*#5773282#*#* - LPP Data Options (LG-specified options for data use. Possibly something not to mess with unless you know what it all means. If anybody could shed some light on this, that'd be great.)
*#*#14640#*#* - GNSS Air Test (GPS)
*#*#759#*#* - RLZ Debug UI (Device ID, Activation Status, Some Ping Stuff, and few other things. If someone could explain "OEM Mode", I'd appreciate it.)
*#*#2432546#*#* - Google Check-In (Used during setup)
*#*#947322243#*#* - Software Update Service (Exactly what it says)
*#*#7253#*#* - Software Update Service (See above)
*#*#52325929766#*#* - LCD Always On (Just a lonely setting to enable the LCD backlight to always be on.)
*#*#54635564#*#* - Modem Protocol (Used for event logging)
*#*#762646427225#*#* - "Fake Roaming" (Still not 100% sure about this. Maybe used for testing? Anybody?)
*#*#6737#*#* - IOT Menu (Menu for VZW. No AT&T function.)
*#*#1472365#*#* - United Protocol Debug (Some pretty useful info, actually.)
*#*#4636#*#* - "Engineering Mode" (Has some useful stuff. My "Phone Information" is disabled. If anybody else's is enabled, please tell me how!)

These ones were in a XML file I was reading, but nothing seems to happen. Maybe I need root.

*#*#79783684#*#* - Unknown
*#*#46#*#* - Unknown
*#*#7867#*#* - Unknown

NOTE
Thanks to phineous for pointing out that some codes can be dangerous! What YOU do to YOUR phone is on YOU! In no way, shape, or form am I responsible for any damages YOU incur on YOUR phone.

That's all I've got for now! Hopefully more soon. If you have any more, or yours differ (somehow) from mine, let me know!!

Beware of running the software updates, mine did a factory reset after checking for updates.

thanksssss!!! this was very useful, I could check if my version was anti rollback enabled

You're very welcome!

I'm glad it was useful for a couple people. Like I said, I'm still like a little kid when it comes to that. Just wish I had access to a noninfected computer so I could [EDIT] root and get the rest of the codes.

Soon, hopefully. Dang rootkits...

*ZIP IT*

I opened the APK packages as ZIP packages, then read through the AndroidManifest.XML. Then I used an app called Dexplorer that reads the rest of the files in the package. It can be found here.

Tried those last three with root, but I didn't get any special actions / menus either.

And, like you, my "Phone Information" area in Engineering Mode doesn't work (or at least a pop-up claims it doesn't). Even though there's clearly information behind said pop-up.
