Problem Solved - LG V30 Questions & Answers

Hi, this is the third time I send an email to LG support and hope I get real support istead of being unprofessionally dealt with or simply ignored due to incapability of the service personnel.
I have encountered a LTE network problem after messing something up in the engineering mode by pressing *#546368#*998# on the dialing interface (after reading this thread from XDA: https://forum.xda-developers.com/lg-v30/help/us998-hidden-menu-lg-v30-v30-t3719219/page1)
I was just curious to find out all the LTE band numbers my phone supports. But after messing up with the menus, LTE network on my phone collapsed. I am quite hopeless Now since reset did not work at all.
apn set and problem solved.

why cannot post the full content

My question is how to restore the original parameters in the hidden menu of US998?

In that same hidden menu mode, I saw network reset choices. Not in the LTE bands section, but a neighboring section. Find it and see if that works.

[Q] Connectivity -phone and 3G issues

Hello ,
I have the Photon for 3 months and i use it in a GSM network .
Few days after i moved to another GSM provider , the phone began having connectivity issues .
In most cases it does not have 3G ,and sometimes I cannot make calls from it (No Service).
I noticed that when i'm with WI-FI ,in most cases i don't have the No Service problem.
I am not sure if this is a hardware problem or network problem (could not find another provider's SIM , if could find one I would check it),because the problems started only four days after moved to the new provider and not from the first day with the new provider.
Could some one help with diagnosing the problem ?
try setting the network to "automatically" and not "any GSM / UMTS"

well, I tried that -it did not help ......
Try putting *#*#INFO#*#* in the dialer perhaps and changing the GSM settings through there?

could you guide me please how to use this menu ?
It sounds like bad APN to me. Make sure your phone is rooted and then get the apparently "apn backup and restore" back up your current APN with it and wipe them out. Find someone else on the same carrier u switched to and have them do the same. Restore their backed up APN . try that and Report back please.
Also for my own Peice of mind: you are using the photon kddi released for the Asian region amirite?

This would be in the settings -> networking and wireless -> GSM settings. Ill post a screen shot but I'm about to PM you anyways because I'm very curious about how this plays out as it could really help clarify some things we have been pondering the effectiveness of in removing the domestic lock on the US photon-4g GSM radios.

[Q] VZW Google Edition ROM 5.9 NO LTE

Hi, I am currently using the VZW Google Edition ROM 5.9 and have service and WiFi. My problem is it only connects to 3G, and not 4G. As advised, I have not gone into network settings, but I did open Phone Info and see that it is set to LTE/CDMA auto. Any reason I am not getting LTE?
Just a thought, but maybe you could check the APN settings and see if they are different than what you should have.

Thanks for the response. I am kind of new to this, where do I check the APN settings and how do I know what I should have? Thank you.
Do you have LTE coverage in your area? If so, can you use another phone/friend to double check if LTE is working? I only ask because we had LTE go out where we live.
Gir brings up a good point, I don't have 4G where I am (and probably won't for years!), but that may be simplest as long as they use the same network (although many carriers piggyback off the same network).
The APN settings should be under "Settings > More networks > Mobile networks > Access Point Names". On a stock ROM you have to get to the actual file through ADB, you should be able to see it if you have an aftermarket ROM. The settings for the APN will depend upon Verizon. Here is a good post with APN settings for Verizon, the first part is for Android.
Coverage could always be the issue as that has plagued me more times than not.
From the ROM thread:
Go into mobile network settings.
Verify that your CDMA subscription is set to RUIM and not NV.
For good measure go into the rest of the options and set it to CDMA/LTE, automatic, and allow data roaming.
Back out to your home screen.
Then go into Phone Info app.
Scroll to bottom and tap radio off.
Open the drop down list and select CDMA/LTE auto (PRL).
Turn the radio back on.
Reboot.
Upon reboot open Phone Info again.
Verify it is set to CDMA/LTE auto (PRL)
** you should have full service now * *
** if not * *
In Phone_Info(*#*#4636#*#*):
Try CDMA auto (PRL)
Then try CDMA/GSM/LTE
If those still don't work then your nv_data needs reset. The only way to do that is in the hidden menu dialer codes in a touchwiz-stocktype rom
If you destroy your nv_data and cannot get data back via the above you need to (stop screwing with your network settings)flash back to a TW ROM, enable hidden menu, and do a NV data reset via dialer code. After doing that make sure your phone is not in modem mode under diag dialer code. Until I update this section Google is your friend. And it is available information, verified. Your lack of searching skills doesn't mean pester my inbox...
I do have LTE in my area, as I had 4G before I loaded the rom. I do not have an APN menu under mobile networks. Do you think it could help to dial *228 option 2 to update roaming? Or possibly a new 4G sim card?
Anything about updating I would research first and be wary of... A new SIM card could help, but I'm assuming it is not the problem. Did you make a NANDROID before you changed ROMs? You could then go back and see it you still got 4G to make it evident if your SIM card is the problem.
FIXED
Just needed a new sim card. Thanks guys. I appear to be receiving signal bars with my LTE on the GPE rom as well.

Phone Info / Radio Menu sections accessible on my Sprint V30+ US LG-LS998 - non root

So a little background on why I'm posting this. I have owned a G4 G5 G6 and V20, all on Sprint, and none of these devices can ever access the Phone Info section or "Radio Info" section as it's referred to on the Hidden Settings shortcutter App. I believe Sprint or LG removes access to this area on all LG devices. On all of the ones I've owned I can try and access the section but only catch a brief glimpse of it when I try to access using a shortcut app. It is always immediately covered by the same message every time which is: Note This application does not work on this device.
Now I just activated a V30+ a couple weeks ago which I received through Sprint's normal telesales channel and on this device I can get to and modify most fields in the section. I haven't seen other people posting about this so maybe it's standard for everyone with the LS998 Sprint variant and no one really cares or just doesn't have anything to say about it. If thats the case, my apologies for wasting everyones time with an unnecessary post .
If my access to this area is a one off situation and could help lead any developers or more avid tinkerers to any discoveries I'd be happy to test out some things together with anyone with more experience than myself. I've been holding off on attempting to unlock the bootloader and haven't done any PRL updates or resets just in case this access is worthwhile as I've been worried something is going to update and take away my ability to get into the section.
I've included some screenshots. I've cropped them to try and remove some of the more personal data but I think all the relevant sections are covered.
*** Below are some questions and thoughts I've had. I hiding the section it to keep things less cluttered for those that are just reading up but dont have any experience or opinion on the settings/functionality etc***​
If everyone can already get to this section, have you changed your bands or modified any of the settings and what results did you see?? I've been tempted to switch up some settings and run some tests but I'm being kinda chicken about changing anything because I can't find any info on people using this menu to do anything except screw up their coverage. A few example seems to be people on different earlier LG models that select USA but live outside the US and then cant get it back to their countries settings.
Here is a list of things I would like to examine more, or try out in these menus. Maybe some of you have already done such or have the same questions. Any feedback would be cool on any of these things or even warnings or endorsements. I would love to learn a bit more about this area and its possibilities.
Under the "Set Preffered Network Type" option I would like to change the current setting of LTE/CDMA/UMTS auto (PRL) to one of the other options and see what happens. I believe this area is relatively safe and can be switched back to the original setting easily. I'd like to switch to Global Auto Mode, Unknown Mode, GSM Auto mode and LTE Only Mode and run some speed tests and see what towers its connecting to in each.
There are four toggle switches, one of which is grayed out. This is the Video Calling Provisioned Switch. Curious if this would possibly become accessible in another mode, or if there was something i could change in a database editor that would allow me to switch this to "on".
The only setting I did change was the one DNS Check. It was originally set to disallowed and I switched it to allowed. I dont really know what changes or abilities this added or took away and have not seen any difference since doing so.
The SMSC when Refreshed will give me an 11 digit number in "" followed by a 3 digit number. It begins with +1 giving it the appearance of a phone number. I believe this has to do with SMS provisioning but am unsure and have not modified the info here.
One part I am very curious about is a grayed out button labeled OEM-specific info/Settings. I have searched like crazy just to try and find some info on whats behind that button and got nada.
In the additional menu section (the three dots) I have an option to Select Radio Band. When Pressed it takes me to a menu which sats "set GSM/UMTS band". This is the area I have found little about other than what I mentioned earlier about people getting locked out of their country settings. I have not touched this setting.
The IMS service Status of my device seems to not populate correctly as I'm listed as not registered or unavailable for all sections as seen in the picture attached. I could swear that a week ago I was showing "registered" but if so thats no longer the case.
Thanks in advance for any feedback.

Do you mean the ones within thd expanded part of the phone info section? If so, I've checked those out and they are blank. Screenshots attached.
So enough people have seen this post now that someone with a V30+ should be able to confirm whether or not others can get to these settings.
Anyone?
There is several other threads about this already. I found them while trying to find a way to get more ?? bands working on my India based phone. Nothing new i don't think and none of it actually helped, for me at least. There is a dialer code for it but i can't remember it.

I'd like to hear what you tried out and see what changed and what stuck and what didn't. . Maybe we can get your phone working better here in the states if we team up on the problem... I know my avatar shows I'm a junior member but that's because I don't really post often, but I do plenty of reading and tinkering myself and I have been in the Telecom business for about 15 years. I'm not an expert or making any guarantees but I certainly don't mind helping out a fellow member here if I can.
Do you have your MSL code? I have mine so if you have yours maybe we can take a look at how my phone is provisioned in the ##data# menu and get your bands setup the same way since mine should already be configured to the proper bands for the U.S. Between modifying that area and making some changes in the Radio info section that could do the trick for you. Let me know if you'd like to work on it and we could PM or you could reply with a run down of what you've tried and how you're setup now and we could go from there.
Cheers.
*#546368#*930#
Field test. LTE band selection. Selecting any band from the menu just makes it completely lose cell signal. After selecting a band it just either says success or fail.

Ok so that dialer code doesn't trigger anythibg on my model. I also tried replacing 930 with 998 and tried replacing the *# and #* with just ## and no luck. But no worries.
I'm thinking you may need to change your settings in two menus in order for the new settings to work together. If you go into your Data menu (##data# or maybe *#data#* on your model) and update the information there to match the ones I am attaching in my screenshots and then go into the Radio Info menu and select a similar setup to how my device is provisioned you may see some success.
Thoughts?
You would need your MSL code in order to change the settings in the ##data settings....
Where do i get msl code?
Neither of the data dialer codes are working for me.
Oh those settings are only for cdma phone?

There are a bunch of tips and tricks to find your MSL code posted throughout the boards, but I have only ever got mine from the carrier. If you call customer service you can usually talk them into giving it to you, though their policy on this is to not give it out unless your phone is fully paid for / out of contract. If you tell them you are working with a tech in a store and need it for provisioning they will normally give it to you.

I know this may not be in the right place but does anyone know how to bypass frp lock on this phone

H961N Network Issue

My H961N does not allow me to independently set my network band for each sim card. Both my network providers operate on 2G/3G/4G however since I have gotten this V10 I have had inconsistent network usage. At first I would strongly get one network and the other would mostly be on Emergency Calls when indoors depending on where I was. I used the hidden menu code *#546368#*961#-> Field Test -> Modem Settings, from Modem Settins I have tried to set the RAT Selection and the Network Mode however when I check Engineering Mode both sims show the same band if I am on WCDMA Only or GSM Only but neither provider operators on the same band except for one on 3G. If RAT is set to selectively move between two or more frequencies then one sim shows Invalid Band in Engineering Mode. Using Network Mode I have tried to set each sim to different band but both would either show the same band or one would appear invalid under Engineering Mode.
Another Issue I have is I am unable to use data even though I have the correct APN for both of my Network Providers. I have verified that both sims do work when used in another phone, at one point I visited both Providers but none could give me an answer to my issue. One of my Providers did however try and activated a data plan while I was in their office and the V10 did show 3G and received data however upon returning back to my regular surroundings I no longer got any data. I have tried upgrading the V10 to Marshmallow and Nougat but the upgrade did not solve this problem, neither the one I stated before. But on Nougat both my sims did show 3G but strangely only when I have my Wifi active and using a VPN. Currently I am on Lollipop and rooted I considered trying to flashing a qcn, sec and nvm files since I saw a site listing them as fixing network and data issues on this particular phone, I have the files just in case. Any help would be greatly appreciated.

Unable to connect to my mobile network

I recently purchased a refurbished phone Samsung Galaxy S21 5G. I just got it yesterday, and found that I am not able to use my mobile network. The sale said it is factory unlocked, and according to the descriptions, it should work just fine with my US Mobile SuperLTE network as well. When I switched on the phone, I see Verizon on the screen and so, I assume that it was locked to Verizon in the past.
When I tried to change the network settings, specifically the APN settings, I get the message "Access Point Name settings are not available for this user." The three dots on the top with reset to default is also greyed out along with Network mode in the previous page. When I click Network Operators and try to connect to the network manually, I am only able to connect to Verizon Wireless and no other. But, calling and messaging seems to work fine. Is it that the unlock process has not been completed properly? Did any of you face the same problem before? It would be great if there is something that I could do to unblock the APN settings as the rest of the phone works really well. The specific model is SM-G991U.
Thanks!

So, you need to go into the settings menu and find about phone, software info. What you want to find is the CSC information.
It will basically look something like this: XAA / XAA-XAA / XAA (or some other letters like VZW or ATT or TMB etc etc.
What taht will tell you is very helpful in determining what rom the phone is running and what kind of device it was originally. Find that in your device and post it and people will help you to figure out what it means.

Thank you so much for your reply. I looked through the software section in the about section. I found the following codes about the rom.

So the csc info is complicated, I'm no expert on it. But it does look like the OYN indicates it's a multi csc rom. It does have XAA as a part of the code, and that indicates it's 'open' for that specific part. But all the others are VZW. So it's running a vzw rom, obviously.
Your sim US Mobile uses both verizon and t-mobile networks. So it working for calls and texts makes sense, as a vzw phone. You could use patched Odin and flash a different (open) rom, but first you should verify that the device really is unlocked from vzw.
Best way to do that would probably be to insert another carriers sim card and see if it can make calls / texts. If not, it's not unlocked. But are you saying everything works now except mobile data? IOW, no internet access?
I had an international sim card at hand and I put it in. Interestingly the APN settings are no longer blocked. But, I do get a notification from setup wizard saying the inserted sim is not from Verizon and some services may not be available. But, messaging still seemed to work and I was also receiving 4G.

Oh then yer okay. That message from verizon can be gotten rid of a couple of ways; 1) use adb commands to disable the specific packages 2) use patched Odin and flash a different rom
VZW is the only rom I think that does that, and it's very annoying. I don't remember exactly which packages have to be disabled, but search google and use xda and vzw in keywords and u should find it.
The 2nd option would be my choice. It would do away with vzw crap and with an open rom you may find volte and vowifi will work also.
cheers
Thank you so much for your reply. That sounds great! To just give it a try, I tried putting in a TMobile sim and phone restarted to install software for TMobile. After that the APN settings were unlocked and now I am also able to connect to the internet using my US Moblile sim. The only problem is the the network mode is greyed out.
This rom I think only recognizes network from major telecom providers. So, just flashing with an unlocked rom would just help to unlock all the features and also remove telecom specific crap. I will try to flash it today.
Thank you again!
I also just flashed the stock firmware which is fully unlocked. And there is no bloatware from telecom OEM's. I am now able to use the network and set the APN's, but the Network Mode is still greyed out. Is it possible to know why? I am guessing that if the phone is fully unlocked, I should be able to change the Network Mode. Is there any other info that I can give you to help understand what is happening? I do not see vowifi as well.
