IOTHiddenMenu (USB Settings, LTE Settings, Test Mode, Dialer codes, etc)

---

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!!

The ##DEBUG# Menu includes the LTE Engineering information screen, which is the only place to find the proper signal strength (RSRP) and signal quality (RSRQ) of a live LTE connection.

I was playing with that and tried Korea mode think it would put the phone in Korean
Disappointingly it didn't now I can't connect to sprint 3g
Some one help

If you have your MSL, you can ##3282#, edit, enter MSL and manually input your username@sprintpcs.com...

run your NV RESTORE... TestMode > UMTS > COMMON > NV REBUILD > NV RESTORE. Make sure you hit the RESTORE setting and not Rebuild/Backup. The last thing you want to do is create a backup of bad nv settings(such as nv settings all being set for Korea mode). After you hit RESTORE the phone should reboot within a few seconds... wait it out. Your phone should now be unprovisioned... so it should try to OTA and that's that. If for some reason the "sktelecom" settings are still set... try running NV RESTORE one more time. If it STILL isn't fixed after that.. let me know. There are a few things we can do. Last night I messed my NV and EFS up pretty bad(sorta on purpose lol) but I was able to recover from everything. Even Korea mode.

Thanks man it worked perfectly
I tried updating profile and it did restore my username but not my 3g
You saved me a whole lot of time talking to sprint customer service bots

prime glad to see you have this phone. I follow your work on previous phones

I'm getting mine in a few days.

Question:

How do I backup NV? Where does it back up the items to? Internal memory?

Is it the same as backing up. NV 1192, 465, 466, and 1194?

hmm good question. to be honest im not sure where it backs up the files. pretty sure theyd still be in NV somewhere.

what you should do is connect gs3 to qxdm.. send 16-digit pass(same as epic/e4gt/etc).. then close qxdm and open up QPST EFS Explorer. All NV items will be unlocked in NVM > NUM. i think thats the folder anyway.. doing this all from memory. but ya... 1192 etc will now be viewable in EFS EXP when you send pw in QXDM first. No more "denied access" in CDMA WS

@auto

Have you figured out LTE is simply a MAC ID authentication?

Can we change LTE Macs and be connected like WIMAX?
