Secret Code Not Working - G4 Q&A, Help & Troubleshooting

Hi All,
I have an LG G4 through T-Mobile. 277634#*# gets me to a hidden menu, but not the device testing one. The “For T-Mobile – 3845#*851#” code didn’t work, and neither did replacing 851 with my phone’s model number, 811. Is there no service menu in my phone, or is there some trick not listed here to access it? Thanks in advance.

HTC Desire and Page Plus

Hey guys, I have a Desire CDMA that was on US Cellular. They claim that the ESN has been released from their network. I have rooted the phone with no problems. Page Plus was able to add it to their network fine but it just will not activate. Verizon, of course, is no help either. Should I find a stock 2.1 and re-flash?
I see people selling Page Plus Desires so I'm needing to know what I'm missing. I did get a guy on the phone who told me the phone needed to be "Manually Programmed". I also went to a Page Plus dealer and he gave me a DUH look when I asked him about it.
I have also installed CyanogenMod V7.0.0 RC2 without any problems what so ever... I just need to change the Network to Verizon instead of US Cellular.
[Edit] I have found out that I need to change the SID number, anyone know where to do this?
Any ideas would be very helpful!
TIA!!
[Edit] I have also discovered the *#*#4636#*#* trick but the OEM info at the bottom of the screen is grayed out... I dont know if this is where you change the SID #? The ##PROGRAM trick did not work but I have already flashed the CyanogenMod so maybe that is why this didn't work?
[Edit3] I found this but the ##PROGRAM is not working, is there another number to get into programming?
-Tap the Phone Icon and dial ##7764726 then tap phone icon
-SPC Password is 000000 and tap verify
-select User Activation
-Tap MIN Box and delete existing info and add your MIN *
-Enter MDN as well
-Find SID # and input it here **
-Press Done to save info an return to user activation and then press Home key and phone should reset after programming
so this does work? and do they give you the numbers you need to enter?

Dialer codes

I have found a bunch of codes as seen on the screenshots below. These are from the h932 but might work on other variants.
*#*#52325929766#*#* - LCD test(weird we have a oled)
*#*#54635564#*#* - Modem Protocol
*#*#00*4#*#* - IPV4
*#*#00*46#*#* -IPV4V6
*#*#00*6#*#* - IPV6
*#*#00*77710#*#*
*#*#00*77720#*#* these five are sim toggles that aren't
*#*#00*77730#*#* supported by my phone
*#*#00*77740#*#*
*#*#00*77790#*#*
*#*#1472365#*#* - United Protocol Debug tool( this has a bunch of options like a on device adb shell but its very limited)
*#*#244773825625#*#* - Version Info
*#*#366243#*#* - EMMC ID
*#*#762646427225#*#* - Fake Roaming settings
*#*#5773282#*#* - LPP Data Viewer[this has alot of interesting toggles]
*#*#32823787#*#* - Data Sanity Test Suite
*#546368#*XXX# - Replace the XXX with model number like 998/930/932. This is the hidden menu.
I can confirm this also works on the v20.

I'll be editing in a while for what code does what, But I think the most important one should be the united protocol debug tool.

I saw your PM about this, but not sure what they will do. After messing up one V30 US998 with hidden menu LTE bands, I'm a little leery.
Still don't know if that one is messed up or not. I switched to V30+, bought my wife a different V30, and that other one (my original with static LTE band issue) which I factory reset is my backup.
I can try these in hidden menus on that one.

Yeah they won't work on that but will work on the stock phone app.
I did try and use your suggestion and install that app but for some reason most of the codes I found for the LS998 are NOT listed in the engineering mode app and most of the ones that are listed in the app for some reason CRASH the APP and basically useless app for my Ls998 could be I have most of the stock apps blocked and disabled could be the problem this APP crashes but I am still working on a work around of unlocking the bootloader in some way there has to be a way because this is man made meaning it can be done at some time or another

Could be the issue. You wont know until you try it again but with most Packages re-enabled and see if that makes a change. If not you're out of luck
I did try it again and when I choose Engineering mode and chose Phone info it tells me this App will not work for this device and Like I said before Most if not all the codes it generates do Nothing at all that are useful .
I even tried it in several modes enable DIAG mode first and do the tests Nothing
Different Sim Cards Nothing none of the codes work on this version of the V30+ ( LS998) (Sprint)
But I am NOT giving up on this phone since I have never owned an LG phone before and this PHONE cost me Absolutely NOTHING $0 dollars so I have Nothing to loose if I brick it
( It was a free-bee from sprint because of account problems but I never activated it and never plan to unless I have full control over the Phone )
I will stick to my HTC M8 its works and looks perfectly

Sprint phones are very locked down.
I know they lock them tight but that intrigues me more to unlock it
I am sure there is a way just have to figure it out.
If I knew what Signature it was looking for during a ADB SideLoad update or recovery I may be able to use the US998 Recovery Image to force a flash and then unlock it I have all the KDZ image files from all versions except the LS998
While in Download mode hit the power key 2 times
This Menu appears but do not know what to do with it
** Select Menu**
** Select : Power Key(Long) **
** Move : Power Key(Short) **
--> MA-USB(WIFI) DL
--> POWER OFF
--> PHONE INFO

So does Hidden Menu: 5689#*998# actually work on your LS998U? None of them works on mine with Android 8.0 updated...
Thanks!
yes they all work at least on my sprint LS998U they do
I am going to just sell the one I have its brand new and everything original with box never been activated so its completely clear
How does ##7764726998 work? The service code is not 000000
None of these bring up the service menu so I can turn off the moisture detection.
Anyone know if any of these codes or the main hidden menu can ask for an APN update push to my US998 using Verizon SIM? Stupid carrier APN lockout since Android 8 means I can't edit the APN setting on my own, even with root. Haven't found an app on the Play store to do it or a Magisk module yet.
Check the LG v30 questions and answers forum for a thread titled "can't receive MMS pictures with third party texting with Verizon"

Snapdragon 425/MSM8917 without PC

Hey all! I have an almost brand-new LG Rebel 4, LML212VL. It has a Qualcomm Snapdragon 425 (MSM8917) SoC. I'm looking to root it. I don't have any other device that I can use, only the phone. Any help is appreciated. I've looked at this thread, but when I install poot and run it, it simply says "Invalid Qt version" and closes. I don't have any computer. Thank you!

I have the same model phone. If I find a root guide for it I'll let you know. Have you tried asking in the lg threads? Maybe go over there and ask around also.
Hello,
I have this phone LG LML212VL. Need to carrier unlock. Any help? I had this sent to me but still could not get anything to work.
How can you check if my Android phone asks for the unlock code?
Option 1
1 - Dial the following sequence on your phone’s keypad as if you were going to make a call:
2945#*model number of your LG#
To find out the model number of your LG:
Settings - About Phone - Model
On the sticker under the battery
For example: If you have an LG 610 type 2945#*610#
2 - The sequence typed will provide access to a hidden unlocking submenu with the following sections:
Network Lock
Service Provider Lock
Network Subset Lock
Corporate Lock
SIM Lock
3 - Check your phone prompts for the unlock code correctly under Network Lock or Service Provider Lock. If it does, you can submit your unlocking request.
Option 2
Insert a SIM card different to the Tracfone - U.S.A. network.
You will be asked to "Enter network unlock code" or for the "SIM network unlock PIN".

Good luck. BEst bet would be to check out "cdma-yemen" they are a talented team of Yemen coders. They always deal with Tracfone and can unlock about anything!

Unlock network bands, enable voLTE and 5G on nonsupported countries

Hi,
Other phone models can use EFS Tool, QPST tool to do all the mentioned tasks.
And some phones to do that requires rooting phone since they dont have Engineering mode, and some with Engineering mode support doesnt need rooting to use the mentioned tools for example OnePlus phone.
So my question, does LG phone also has this thing called Engineering mode? since LG wing is not supported for bootloader unlocking by LG yet.
Anyone has more experience with LG phone and perhaps the mentioned tool can shed some lights on the concern? Thanks.
Goid app. Well made
on LM-F100EMW,
1) use dialer code #*462633*#100#
2) go to Field Test > LTE Data Test > Tethering Mode, and select QMICM
3) go all the way back to first menu and go to SVC Menu> Port Check Test> Port Check Test and select enable
after that I am able to connect QPST. I used EFS explorer to fix CA-combos and carrier policy for my region/provider.
After doing your work, revert the changes to have a regular USB connection!!
for VOLTE first try to
1) make a new file or folder with name "enable_ue" (without quotes) on your phone's internal storage.
2) use dialer code #*462633*#100#
3) go to Field Test> Universal Enabler > Create New Config , enable VoLTE and confirm.
to add VOLTE indicator next to battery and signal strength on notification bar
1) use dialer code #*462633*#100#
2) go to Field Test > GPRI VoLTE/VoWiFi > IMS> select Sim Slot > Registration > VoLTE > and enable VoLTE Indication.
after all these
1) use dialer code #*462633*#100#
2) go to Field Test> IMS Settings> select Sim Slot > Test > Restart IMS process > select Yes
now you should have VoLTE enabled with notification bar indication

This is a good write up!Thanks for this!But,what modifications are you making in EFS Explorer to fix CA-combos and the carrier policies?I have a T-Mobile branded Wing,and I'm trying to enable VoLTE AND VoWifi for AT&T since this 3g shutdown went in effect?Mostly conerned with the VoLTE part because I can't make voice calls without it.Thanks for your help.

For volte i didnt change anything from EFS.
The changes i did in EFS was to add 5G for any carrier, because my carrier was not supported, and also to take the CA string from another phone's firmware, that my carrier has good support, and paste it where the outdated ca string was inside my wing's EFS.

Hi. I have LG wing unlocked dual sim. But not getting volte. Tried the hidden menu option. It is showing in settings but looks ims not registered. Can you tell if you were able to get Volte on LG Wing without mbn loading. Also if mbn loading is needed, what is the process and where do you find the files for LG wing Malaysia carriers that I can use. I have another Samsung phone and that is fully volte supported. Can I copy something from it?

When i go to field test and click on ims settings it is showing not supported. I formated my phone and it became like this. Before formatting it used to work and I could see ims settings. My phone I bought from a shop and the shop keeper sent it rooted. Thatd when IMS settings were working..but after I did a reset saying not supported. How to bring it back?

When I go to field menu in my Lg Wing, I go to IMS settings, it is completely blank. Someone please help me in registering the Volte in my Lg Wing. I am already rooted by able to patch the stock boot.img using magisk. My phone came with an unlocked bootloader and its the European firmware. I am trying to use this phone in Asia (Malaysia). Surprisingly, when I got the phone from the seller, it was not enabled volte but IMS settings in field menu would also show up (unlike now when I go there and it is blank), and also surprisingly, my volte worked also but by mistake I formatted my phone and after that it never worked. I then tried to flash the stock firmware and did root, installed voenabler but nothing seems to be helping.
I even tried loading mbn files of different carriers via PDC but no help. IMS settings always stay blank and volte doesn't get activated. Such a good phone but not able to work because my carrier here only supports volte.
If someone has an interest in helping, will be great.

No IME number assigned or service menu accessible

Hi,
My wife got a test model from her friend who worked for Starbuck. The phone can with the original box and valid IME number, but Verizon can't assign the Number to the phone. The rom seem to be lock and can't access the service menu either.
Can I flash a new ROM on it? Will this give me access to the system and access the service menu?
Any help would be much appreciated,
Peter
