[Sprint Samsung Galaxy S III] autoprime:
Most noteworthy edits include LTE only mode, LTE/CDMA mode(no 3G) and NV BACKUP/RESTORE. Nice little all-in-one shortcut for most of the hidden menus on this device.

If there is another thread on this in the Sprint Galaxy S III forums I apologize. Just going to outline this menu which is found on stock Sprint GS3 Touchwiz roms.

Getting Started

You can use Any Cut, Better Cut, Nova Launcher etc etc to make a shortcut to this menu.

1. Better Cut > New ShortCut > No > All Activities > IOTHiddenMenu(first one listed).

2. Any Cut > ?

3. Nova Launcher > Long press on home screen > Shortcuts > Activities > Scroll to IOTHiddenMenu and click it to expand > Scroll down to the first IOTHiddenMenu in that list(under GPSCLRX)

Now we can open our new shortcut and you should see the following screen...

USBSetting Menu

This menu switches the phone's USB mode when connected to a computer.

MTP (Media Transfer Protocol; device shows up as USB drive)

MTP + ADB (default setting; should be self-explanatory)

PTP (Picture Transfer Protocol; device shows up as camera)

PTP + ADB (should be self-explanatory)

RMNET + DM + MODEM (RMNet = USB virtual Ethernet framework; DM = Diagnostic Mode; Modem = self-explanatory)

DM + MODEM + ADB (self-explanatory) (best setting when using QPST/QXDM/etc)

LTE Mode Menu

I do not have LTE in my area yet. Could anyone detail what some of the options below do exactly? I'm sure one is for LTE only.

TestMode Menu > CDMA > COMMON > NEXT PAGE > NEXT PAGE > PREF MODE SET may be the better alternative to this.

LTE Service Forced

Enable LTE Mode

Enable GLOBAL Mode

Enable CDMA Mode (default)

TestMode Menu

1. UMTS

UMTS > COMMON > NV REBUILD (NV REBUILD, NV BACKUP, NV RESTORE)

Everything else under UMTS either doesn't work.. or isn't worth messing with.

2. CDMA

CDMA > COMMON > NEXT PAGE > NEXT PAGE > PREF MODE SET (CDMA/EVDO/LTE, GSM/WCDMA, LTE ONLY, CDMA/LTE, CDMA ONLY, EVDO ONLY)

Everything else under CDMA either doesn't work.. or isn't worth messing with.

3. LTE

Nothing of interest.. just displays LTE debug status.

4. SIM

SIM > CHECK NV (Helps identify possible incorrect settings. Displays current PREF MODE. NV should be set under RTRE Config.)

Not worth messing with anything else in here.

5. run EFS SYNC()

Doesn't do anything.

There are lots of other options in here to mess with but most are broken, not supported or just really not worth messing with. All the MSL settings for example... no matter what.. I can't seem to read/write a new MSL via Test Mode. CDMA > CONTROL > MSL Edit has broken my MSL. *Update* Fixed MSL. I also messed up my EFS playing with the wrong stuff. I was able to recover.. but BE CAREFUL!!
