I have lgk7 ms330 thru metro pcs the phone is unlocked by them. Now I see it does not work with certain 4g Bands how to access the service menu to enable those bands?
I have the same problem with my lg K7, it's a T-mobile device. Mine works only the 2G / EDGE BAND. I did unloked the bootloader, also tried build.props but nothing changed, it seems that the other bands are still locked by the manufactor.

It's an lg lte 4g model. i put here more software info.
android version 5.1.1
baseband version
MPSS.JO.1.0.c5.7
kernel version is 3.10.49
Software version K33010l
It does not work with certain bands because the flashed modem on the device doesn't support those bands. This is an OEM problem that would be fixed by a custom rom.
Hi I have a lg phone k7 The problem is that it does not support 4G or 3G only 2G so that my country where I live is a 4G signal please help me ???
So I just read and saw on line that the US Cellular version of the LG G6 is on $550 buy it out right. Would this version work with Verizon Wireless. It looks to have the same LTE bands. What would be the chance of buying and putting a Verizon sim in it and it works out the gate. Anyone have any ideas?

GSMarena doesn't currently list 3G bands for the US Cellular G6 (US997). However, I've seen the Verizon and US Cellular versions of phones differ on 3G bands before (see the Galaxy S7 USA, for example), so 3G might have problems if you just popped a Verizon SIM card into a US Cellular G6.
I'm wondering if there could be a similar method to the one that was discovered for the HTC 10 where you flash radio images from the Verizon variant onto another phone:
https://forum.xda-developers.com/verizon-htc-10/how-to/vzw-how-to-unlocked-model-vzw-t3376743
Is the us cellular version factory unlocked? It is the same model number as the unlocked version, us997. I'm looking to use on AT&T.
It looks like you have to pick up some kind of plan from them to get the $550 price. It's probably better to go the b&h route (or hope vzw does a mother's day week sale).
Update: Ended up buying a new us cellular us997 for cheap. Popped my straight talk/at&t sim in and it works flawlessly. I always use this site to check bands
https://www.frequencycheck.com/compatibility/0Dlph6Y/lg-us997-g6-lte-a/united-states
I have used that site several times and its always been accurate. From what im seeing, the us cellular model supports all of the bands needed for verizon. It doesnt support CDMA2000 1xEV-DO Rel. 0 but does support CDMA2000 1xEV-DO Rev A. So if 3G is a major concern, I'd check and see which one is used in your area. I personally wouldn't care about the 3G considering the price difference of the USC model and the fact that all LTE and voice bands are supported. Hope this helps

I am only guessing, but based on what I know about the Moto x, and all moto phones seem to follow the same rules now days, but the bands were what they advertised only. There was no way to add any other ones.
I get that... I think the same radio is in the "Verizon" version as the "Retail Unlocked" version...
Just a matter of Firmware activating the additional bands..

Radio's don't unlock bands as far as I know. The phone usually has the bands or it doesn't. Some phones may have some bands that aren't active, and can be "unlocked", but I'm not sure Moto does this.
But radios, that can be flashed, don't affect which bands are available. Neither does which carriers firmware you flash. If you even can without having severe issues. (again, talking moto here. Other manufacturers can be different) Afaik
So my phone has been running great since the conversion and still flys on ATT LTE, however I am a Mobile rep and I switch carriers on occasion, hence why I was wondering if the US998 modems actually enables the 800mhz CDMA band and allows me to use the verizon LTE bands.
Im not new to flashing and trying things out, and I can easily get my hands on a verizon android sim (yes there is a difference) to test anything.
Thoughts?

The US998 is the "carrier unlocked" version, and many people have used US998 on Verizon, so there's no question the US998 has that band.
Converting any other North America phone to that should let you have all those bands of the US998.

Ill have to test APN settings and clean boot with a verizon sim then. Ive tested a sim and it pulled phone number, but was still looking for signal.
Try making a backup in TWRP, and then flash JUST the Verizon system partition and see what you get.
rild is the daemon that talks to the modem, and Verizon may be slightly different.

LOVE success stories like that.
What is the verdict? H931 on CDMA yay/nay?
It works just fine. Just depends on the rom you use. On stock us998 i can get verizon to work but on boombox, i cant get a signal.
Hello. I'm planning to buy H931 and do the Frankenstein conversion to us998. The question is H931 doesn't have the UMTS 900 band but if I do the process for us998 will I have UMTS 900 or is a hardware thing?

You will have all bands of US998.
The Frankenstein instructions make that clear.

Im sorry my English is not very good. But is unbelievable that H931 doesn't show UMTS 900 band on official description and doing the Frankenstein conversion you can add that UMTS 900 band. So it means that is disabled wow.
Another question. If the H931 AT&T model is not unlocked and I do the convertion then will be unlocked? Or I have to buy the unlock code for the IMEI???

Yes, AT&T H931 will be SIM card unlocked/network unlocked when you convert to US998.

OP, can you confirm that you can use LTE band 13 on your H931 (AT&T) Frankenstein phone? I converted my VS996 to US998 10b, unlocked bootloader, updated to 20e (KDZ), and rooted with magisk 17.3. I can use T-Mobile VoLTE but can't connect to their LTE band 12. I've tried the US998 Hidden Menu hack by using T-Mobile's LTE band menu and selecting LTE bands 2, 4, 12, 66, and 71. When I leave only band 12 selected I only get 3G or 2G EDGE. Maybe T-Mobile doesn't like my phone's IMEI as it's from Verizon. On AT&T, I never got stable LTE because my old G4 was from T-Mobile, and it always dropped to 3G after a while. If hardware isn't the issue then it leads me to believe T-Mobile whitelists only their branded devices for band 12.

I get the success message when clicking on band 13 in the hidden menu. I am using the latest stock US998 rom. Its given me the best reception and still runs fluid as can be.
Also, did you just insert your sim card into the phone from your previous device or did you manually enter your IMEI to your phone number in your T-Mobile account? Is the sim card brand new or several years old? Not being nosey or questioning your ability, just making sure your device properly activated on T-Mobiles network for best network performance. I don't think T-Mobile is picky with verizon IMEIs as 99% of verizon phones are sim unlocked out of the box and T-mobile likes to advertise towards verizon customers.

My T-Mobile service is actually through Tracfone. I activated it on a G5 H830 (TMO), and then moved over to a V20 H910 (AT&T). I did notice poorer reception on the V20 because I rarely locked into band 12. I always had excellent reception on the G5 and frequent band 12. I tried this SIM just now on a Canadian G6 H873 from Videotron, went into hidden menu *#546368#*873# -> Field test -> Modem settings -> LTE Band Selection -> Band 12. I instantly got Band 12 locked in, but went back to Automatic mode: (Field Test -> Network Mode -> Automatic). This band selection menu leaves you locked to that LTE band only, and you can't select multiple, so I went back and got Band 4 which is stronger in my house. If it were rooted, there's a hidden LTE menu that allows you to select multiple bands (through "tmo only" and iot menu, search LTEBand and BandSelection in shortcut master lite when rooted). Doing this on my VS996 -> US998 it falls back to 3G as it can't find Band 12 for some reason. I've tried wiping the modemst1 and modemst2 partitions to no avail. I'm now on the AS998 (ACG or C-Spire?) 20b KDZ. It should be identical to the LS998 (Sprint) modem and supports bands 2, 4, and 12. I kept TWRP recovery by not flashing the recovery in LGUP, INSTANTLY GO INTO FACTORY RESET (Power + Vol up) or else recovery will be wiped, flashed magisk 17.3, Disable_Dm-Verity_ForceEncrypt, lg-rctd-disabler, erased modemst1/2, and booted up. The hidden menu in the AS998 has all bands greyed out in the hidden menu only accessible through root, and the LTE band selection menu reports FAILED on all bands, so it's locked to the stock bands of the AS998/LS998. I'll report later on my findings.
TWRP Terminal command to wipe modemst1 and modemst2:
Code:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1 bs=16384
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst2 bs=16384

I'm confused. Do they want band 13 or band 12? They started talking about band 13, then started talking about T-mobile band 12.

I want band 12, I just found it amazing that OP has band 13 and CDMA on his H931 -> US998. Mainly because the H931 is GSM and shouldn't come with an ESN/pESN, just IMEI and MEID. And due to Verizon being picky about devices. I had an RS988 G5 and that didn't work well with them.

Not mine, I converted a VS996 -> US998 and don't get band 12 or 17. I the same SIM on a G6 from Canada (H873) and band 12 works on Tracfone via T-Mobile and on AT&T (prepaid).

No one else has said this, in fact the opposite.
I'm not talking about T-mobile at all, as they have put specific requirements on their band 12 due toWifi calling, etc.
But many are using us998 on T-mobile, whether converted or original.
That doesn't prove you don't have band 12. Also, ATT no longer calls band 17 as 17. On all newer phones, it's band 12, as 17 is a subset of 12. If you look at the H931 specs it says "12" , not 17. Their 12 is fully interoperable with T-mobile band 12 and includes 17.
