Need H918 (and other versions') mcfg_sw.mbn file for US VoLTE on H990DS - LG V20 Questions & Answers

I recently found out that the mcfg_sw.mbn file somewhere in /firmware/image/modem_pr/mcfg/configs/mcfg_sw may potentially contain modem config options that could enable VoLTE on this phone for US carriers, like T-Mobile US for me. I need the file, preferably from someone with an H918 (since this version supports T-Mobile VoLTE and can connect to band 12, which requires VoLTE to be working). What I want to do is use part of this guide to enable MCFG Buffet and point it to the H918 mcfg_sw.mbn file. So far I am using a "tmo" file I found in that general location under "na" in the mcfg_sw directory, but IMS doesn't connect. Any general help would also be appreciated. Thanks in advance!

US band configuration files?

Does anyone have the band configuration files (from /system/etc/motorola/bp_nvm_default/) for a stock AT&T Flipout? I am not able to reflash the AT&T firmware and the european configuration files are not working with T-Mobile's network.

S8 Custom ROMs and AT&T WiFi Calling

Are there any custom ROMs (and CSC files) that allow the S8 to successfully have WiFi Calling and VoLTE on the AT&T network??
I am running RENOVATE ICE 3.0 but you need the Notorious Kernel 1.9 for Volte to work on T. Some kernels do not support Volte, but Notorious does. You also need to flash ATT from the Flashable CSC Selection V1.0.0, and create/edit the /efs/imei/mps_code.dat and put ATT in there. You can also delete the /system/omc/ATT/res directory to get rid of the annoying T jingle and boot screen. You then need to call ATT and ask the friendly customer service person to update your IMEI. But when you give them your current IMEI, they will not be able to find it since it is not a ATT phone. So they will use the IMEI of a similar phone. That will get Volte to work. But WiFi will not as I think the IMEI must match exactly in their system for WiFi to work.
Hello. I'm also trying to figure out the same. How can I unlock the G955U? is that even possible?
Ideally I'd like to get the CSC Patch installed so I can get WiFi Calling on ATT, as I do not have any reception in my area. Any Help here would be appreciated.
Can anyone help here? Thanks.

You can flash csc seletcion after the rom.
That package contains the csc of att and the US generic. That generic is the one that I use and it works volte, wifi calling in tmobile ...
Hi Eddie, would you happen to know how to Root the G955U? its the Unlocked version of the phone. I've followed every step for CF-Auto-Root through Odin, but it fails every time. It seems like the Bootloader is locked? Any help would be appreciated here.

If you mean network unlock, then follow the ToS on AT&T mobile and eventually you will be allowed to unlock your phone. And for you to switch from the firmware of SM-G955U to SM-G955U1, you gotta go to this forum: https://forum.xda-developers.com/galaxy-s8/how-to/rd-carrier-switch-root-snapdragon-t3597473
You will not get wifi calling unless u can provide to att an imei from a device that has wifi calling. Only feature u will get working is volte. It's different them tmobile.

Thank you for the answer
I am familiar with the need for an IMEI from a branded device ..... But I'm not even completely sure that's working for the S8+ like it did for my S7
I just haven't gotten anyone to 100% confirm WiFi calling on AT&T even with proper IMEI

Well i don't know from experience with at&t firmware but at&t should have wifi calling by default. If not and if wifi calling is an important feature towards you, then the last resort answer you have is to flash unlock firmware onto your device since that's the firmware everyone can use while it supports wifi calling and VoLTE (Voice Over LTE)

Once again, per other threads and myself, simply flashing the att firmware will only give you VOLte. You can toggle the wifi calling but it will say your account doesn't have this feature after about 5 seconds. If u call them and give them an imei number that is to a device that is an att device with the feature it will work. This is different then tmobile which will allow u both without doing anything except flashing their firmware.

Hello all ..... ( and @Tkkg1994 )
I'm still trying to get a definitive answer --- Has anyone personally been able to get an unbranded S8 or S8+ to activate WiFi Calling on the AT&T network (not TMo or others) ??
I'm trying to facilitate an issue with using S8 Ports on my unbranded S7 Edge where we can get VoLTE to work nicely but WiFi Calling will not activate (on the S8 port based ROMs).
I am aware (and have been for quite a while) that you must have an AT&T branded IMEI to get this to work on AT&T. I am also aware that this step is not needed on TMobile or really any other network.
I have tried the branded S7 IMEI that works great on my S7 to activate WiFi Calling while using many (most) S7 based ROMs. I have even tried branded IMEI's from ATT branded S8's and S8+'s .... but I can't get WiFi calling to activate while on any of the S8 port based ROMS (I get VoLTE nicely with many ROMS esp the latest BatMan S8 port ROM)
So to troubleshoot I am trying to confirm that even with the S8 or S8+ that WIFi Calling is or is not a possibilty ??
Thanks

I am no developer, but I believe there are two possible causes in the case of T WiFi failure on Exynos:
Perhaps T requires the IMEI to exactly match as a security measure, and since they cannot use an International model IMEI it will never work.
Or there is something specifically compiled for the Snapdragon process and so when it is extract it will not run on the Exynos.
Either way, it won't work. I posted a LOGCAT when enabling it failed, but it is beyond my capability to debug and no one seemed to be able to figure it out.

LG V20 H910 AT&T - 4G Band Issues

Hello good people,
I live in the UK, where the V20 was not released.
I have bought the AT&T unlocked H910 from Ebay, as it was stating that it works in the UK,
but the LTE band used by my carrier 800 MHz band 20 is not available on this phone.
"LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 12(700), 29(700), 30(2300)"
I have followed some of the noob guides and reading for days I believe that I have successfully rooted the phone, (shows in root checker). - as after some reading I was led to believe that by rooting the phone i would be able to change these settings via an app. however this did nothing for me.
could someone please kindly point me in the direction so that I can mod this so that the phone picks up and communicates with the correct Band? is this possible at all? or should i just try to return this to stock and return the phone?
or is this a situation where i just bought myself a small tablet?
I would be grateful for any help in solving this issue,
Many thanks in advance ! :good:

Hi
You need to get into the service menu on the 910 and search for the 20 band and enable it. Sorry I cannot be more specific. You can google for the code(s) that will get you into the service menu.
I have a V20 but it is Verizon vs995 which has the correct bands but for some reason will not work with EE 4G only 3G.

Thank you for your reply,
I have tried this, i think i can get in by code *#546368#*910# assuming that this is what you are talking about?
this will take me to hiddenmenu
with 4 sub menues
- device test
- ELT Test
- SVC Test
- Field Test
I believe that i've seen people try to access the modem settings in the field test option
and i have seen that people get 3 or more options in this place, (third allowing you to select band) where as I only get 2
- Engineering mode
- PDP settings
do you know why the option does not appear for me?
- Would there be a chance that the option was hidden from the start by AT&T ?
Also I did not do LGUP dump before the root where many people in their guides have pointed out to
do, i followed a guide which does not involve LGUP to attempt to root my phone, should I try to flash the phone in a different firmware to try to unlock the mode ? along with the LGUP dump ?
again, thanks for the response !
Sorry, don't know but have you tried SVC entry I seem to remember some in the US using that to alter their Band.
The code you used does not work for me on my V20 in fact apart from IMEI code *#06# no codes work o. My phone.

If you are in the UK then you don't need H910 rom. Flash it with US996 [usa] KDZ and that will sort out all the band issues without having to do anything more. Plus get's rid of At&T bloatware as US996 doesn't have any carrier bloat or network restrictions. I'm in Ireland and the rom is working great, 4G+ etc. My phone was originally a Verizon model.
edit: One drawback is you will loose FM radio as it's not on the US996 rom. If you are able to root the fone you can get it back with my mod if your on oreo.
thanks don't want to use the FM radio so will try your mod. Is there a guide to flash US996?
I'm being told in another thread that flashing another rom can't give you extra bands, so I'm a little confused between the contradictory advice.
ROMs do not have anything to do with available bands. Bands are hardware dependant

Your answer is in bold. He just gave bad advice. If you look earlier in the thread the Verizon variant has those bands already.

You can buy a US996 v20 on eBay for $86 with free shipping in the US. Probably your best bet. V30 and G7 unlocked phones aren't too expensive either in good condition, though I have not cross referenced which bands they have, so you'd have to double check. I like the phone myself, might buy a couple so relatives have backup phones.
Let me be clear. The H910, VS995, US996, on a hardware level have exactly the same motherboard, The only difference is the software...the ROM. So for example VS995, US996 don't have FM radio out of the box where H910 does. This is a perfect example of where the sofware has been designed to restricted FM radio leading one to *think* the fone doesn't have FM radio on some models at all but in fact it does.
So, It the same idea for BANDS. A fone MAY be missing bands out of the box because the ROM has been designed to restrict some of the the bands where in reality the fone has those bands. So in that case you can overcome this by changing to a ROM that does not have this restriction enabled in the ROM, in exactly the same way as in the case of FM radio. Carriers do disable bands on fones for their own devious reasons.
I know from experience H910 has hotspot restrictions as well. There is a work around OR you can just flash US996 that does not have this hotspot restriction. Also H910 has restriction in the Mobile Settings section. If you change to US996 there will be extra settings in Mobile networks>System Select settings which are GLOBAL / LTE/CDMA, LTE/GSM/UMTS. These options I'm sure I recall did not show up on H910 rom which could be useful to some.
I did not have an original H910 but all I'm saying is that I'm fairly sure that the motherboard is exactly the same as the other models in which case it will have all the same bands as Verizon and US996, just you can't see them because of H910 software on it. Of course you can't enable bands if they don't exist on the motherboard but you can if they do exist but have been restricted by the ROM.
So to the guy who asked about the H910 you can try to use the service menu to enable bands BUT this is not the best way to do it as the service menu might not let you or maybe the enable doesn't last after rebooting. The best way to fix this is to flash a ROM that does not have network restrictions and then you can forget out it from there on in.

Please see my previous post.
You have 2 options. You can either flash a clean US996 KDZ that you download at https://lg-firmwares.com. You'd need LGUP to flash it, guides on youtube and here, search for them. You don't have to be rooted to flash a new KDZ.
If you are rooted you can just download a custom ROM from here such as WETA ROM US996santa version and flash it in TWRP. You could backup your current system just in case it doesn't solve your problem but even if your problem isn't solved the US996 rom would be better anyway for the other reasons I mentioned in my previous post plus I forgot to add that would get rid of all the AT&T bloatware as well.
thanks for the advice, I'm really struggling to find a guide that matched my requirements or is there a generic guide I can follow. Bit scared as I'm reading some roms will brick the device.
Don't need to root at the moment so hopefully that will make it simpler.

Hi there - can you please point me to the rom you use? I just got a H910 from ebay at&t 'unlocked'. But I found only 2g on the stock rom. Have flashed a variety of U996, H915 (canada), and a H910pr (puerto rico) but can only get 3g sometimes. Some of the android 7 roms don't even have 4g as one of the options. Others do but I cannot select it - only 3g.
I'm in the UK but the 800/1800 bands Ireland uses are also the same for EE in the Uk.
Many thanks!

How to unlock network bands on Verizon unlock phone ?

Hello everyone so this my history I'm on T-Mobile Network and I have a Verizon v20 unlock phone everything working good just the internet is slowly so I searched about how to enable bands (I can't find something clear ) on Verizon v20 to make it work on TMobile (full LTE ) its this possible ? Is there some mode or something the really work (Unlock bands) like I said already searched but I can't find something really clear
Note : I have just H sign allway on like other user experiment jus show 4g lte for a minute
Thanks on advance
If I understand you correctly, perhaps you need to set up an APN for T-Mobile. It'll be under Settings->Networks->More->Mobile Networks->AccessPoint Names.

Well I already have the TMobile APN and I trying to figure how to get lte because I have only H icon and no Lte (speed) so what the asking is if is possible activide TMobile band like 7 , 12 etc ... Thanks for your reply ?
Well, you came from Verizon CDMA and T-Mobile is GSM. As long as you've got the proper values in the T-Mobile APN (and you got your sim from T-Mobile), I'm not aware of anything else you can do. Could be wrong, though.
Good Luck!

Thanks I'll keeping searching if I find something I'll post here but if someone have a information about how to making work (unlock frequency's band ) more than welcome ?
The ONLY way I could is to flash another carrier or us996 custom rom. The vs995 rom apparently forces the phone to connect to Verizon towers and bands only. Can't edit in any secret menus, nothing, that's the only way I could. Tip, if you want to use wifi calling, flash a custom stock TMobile room not us996
Interesting so there is a way to flash us996 (Spring correct ?) rom on V995 ? Anyone know what's the safe way if is possible ? ?

Flashing a tmobile rom on a nontmobile phone is a great way to brick. Best case it won't boot and lets you flash back, though it could trip ARB as well making it impossible to roll back. The kernel uses a different security key than the other models.
Has anyone tried flashing a Non.Hlos.Bin from which-ever carrier you are wanting to use?
I don't own this phone, I just by chance took a look at this thread.
Yes of course you would need the correct APN. But you may also may need to flash the modem file from the carrier you are wanting to use. ( It can be extracted)
Another option is using QPST.
With QPST you can change the IMEI, add bands, repair a bricked phone, flash a rom etc. These are just suggestions for things to try. Again, I do not have this phone.
Old thread I know, but if you or others have this problem, have you tried using the LG hidden menu (accessed using dial screen)?
*#546368#*996#
If you have the 996 version, just copy & paste. Otherwise, just change 996 to what model you have.
Field Test > Modem Settings > LTE Band Selection
Select the band you want to use/test, then wait a few seconds for it to register. Your signal will drop for a moment, then should show 4GLTE, if you selected the correct one. There may be more than one that works, but one may be more congested.
You should find a list of available bands for your carrier, before messing around.
Also, do not mess with other settings, or you could really screw up your phone I know from experience.

Cross Flash From VS995/Verizon Unlocked to US996/US Unlocked?

I've been looking for a good, inexpensive phone my partner can use on AT&T, T-Mobile and Verizon and I was able to snatch an unlocked VS995 in excellent condition for $70--it just needs the battery replaced soon which I also ordered. The main downside to this model if you're using it on AT&T and T-Mobile is that it doesn't support Band 12 and 17, but I know the US Unlocked variant does. I just received the phone today. I've been searching on the forum for an answer into if this is possible with the VS995 variant and I've seen people say it is using an LG V20 version of LGUP, but haven't found anyone that's confirmed they've been able to do it on the Verizon and not the AT&T variant and the steps they took to do so.
I want to stay on the stock ROM so I'm not looking to root and install a custom one. Is it possible to convert from the VS995 firmware to US996 so I can gain band 12 and 17 while removing the Verizon bloatware and staying on the stock ROM/OS? If so, would anyone one of y'all be kind enough to post the link to a guide or article that details how to do so? I reset the phone to factory settings so thankfully don't have to do a backup. After doing this, is it still possible to receive OTA updates and, if so, are they gonna mess anything up like reverting the phone to stock firmware or the phone's unlocked status?
Thank y'all so much in advance.
I have a vs995 and I flashed it with US996_usa and working great. You need to download the us996 usa version (2.3GB KDZ) at lg-firmwares dot com and flash it with LGUP PATCHED. There is video on Youtube giving detailed instructions. You will be able to find all these easily via google. I don't know how any of this works with the various US carriers or bands as I'm in europe.

I've been searching on the forum for an answer into if this is possible with the VS995 variant and I've seen people say it is using an LG V20 version of LGUP, but haven't found anyone that's confirmed they've been able to do it on the Verizon and not the AT&T variant and the steps they took to do so.
I want to stay on the stock ROM so I'm not looking to root and install a custom one. Is it possible to convert from the VS995 firmware to US996 so I can gain band 12 and 17 while removing the Verizon bloatware and staying on the stock ROM/OS? If so, would anyone one of y'all be kind enough to post the link to a guide or article that details how to do so? I reset the phone to factory settings so thankfully don't have to do a backup. After doing this, is it still possible to receive OTA updates and, if so, are they gonna mess anything up like reverting the phone to stock firmware or the phone's unlocked status?
Thank y'all so much in advance.

As far as I'm aware, cross-flashing firmware on the V20 won't give you any additional frequency bands unlike some other phones, so you're still limited to what the VS995 has from the beginning. From what I've read, US996 firmware works fine on Verizon except for a few features such as WiFi calling and video calling.
As for AT&T and T-Mobile, you won't get VoLTE or WiFi calling along with the missing LTE bands, so, depending on where you live, overall coverage could be significantly worse than having the H910 (AT&T) and H918 (T-Mobile) models, respectively. Not having VoLTE would be a problem if you were in an LTE-only area without roaming because then you'd have no way to make or receive phone calls.

I have a vs995 and I flashed it with US996_usa and working great. You need to download the us996 usa version (2.3GB KDZ) at lg-firmwares dot com and flash it with LGUP PATCHED. There is video on Youtube giving detailed instructions. You will be able to find all these easily via google. I don't know how any of this works with the various US carriers or bands as I'm in europe.

Thank you for the info. Are you referring to this video? I'd watched it before but it's for flashing the stock ROM on a US996 variant and the links in the description don't work.

Hmm, where did you read that? From what I've read the hardware/modem in the VS995 and US996 version is the same and therefore the difference only comes down to the carrier firmware artificially disabling bands the device supports just like it is on many other smartphones. I could be wrong, but one way to find out would be to do it myself and then try to connect to a Band 12 or 17 tower.
WiFi calling and video calling I'm totally fine with not having. Never used or needed them. With AT&T and Cricket I've never not had service and with Metro the couple times I haven't had T-Mobile service roaming has kicked in and saved the day. Thank you for the info.

Here's some frequency band info for both the VS995 and US996:
VS995
US996
I'm pretty sure this is a hardware difference, and no firmware change will be able to add more band support unlike some other phones you may have heard about (such as recent U.S. models of Samsung phones). Otherwise, there would have been plenty of discussions and guides around here regarding this (and FWIW, I happen to own a US996, LS997, and H918).
As for LTE Band 12 on the T-Mobile network, only phones that are certified by T-Mobile will be able to access it (more info on compatible phones here). So even though a US996 has the hardware for connecting to Band 12, you wouldn't be able to use it since T-Mobile has blocked access to it and only allows it for the H918 model.
Based on all this, I would expect a VS995 to get LTE Bands 2, 4, and 5 on AT&T and T-Mobile. Of course, since you already have the phone, there's only one way to find out. Just make sure you carefully read the guides/procedures about using LGUP for cross-flashing, and absolutely stay away from any H918 firmware (it will instantly kill any V20 that is not an actual H918). Not sure if there even is a separate guide around here as it is usually mentioned in the initial steps of different rooting guides for each V20 model, but you can find the patched LGUP that ezzony mentioned in this thread (you may have to move the DLL file to a specific folder location for it to work properly).

Yes, but the Frequency Check website only looks at firmware differences, not the internal hardware. I decided to do some further digging and went to the source that tests these (the FCC) and found that the VS995 and US996 have the same ZNFVS995 FCC ID meaning they share the same internal hardware. Verizon just decided they wanted to be arseholes and cripple the phone's band support in their firmware so it wouldn't work to the best of its abilities on T-Mobile's and AT&T's network. Similarly, T-Mobile decided to also be arseholes by artificially limiting Band 12/VoLTE support to their own H918 model only. I hate that carriers are able to get away with this BS. It is incredibly anti-consumer and infuriating. If the hardware supports XYZ then it should be enabled and capable of taking advantage of it. The FCC tested Band 12/17 to work properly on these and says regarding the device's capabilities:
This device contains the following capabilities: 850/1900 CDMA (BC0, BC1), 850/1900 GSM/GPRS/EDGE, 850/1700/1900 WCDMA/HSPA, Multi-band LTE, 802.11b/g/n/ac WLAN, 802.11a/n/ac UNII, Bluetooth (1x, EDR, LE), NFC LTE Band 12 (698 - 716 MHz) overlaps the entire frequency range of LTE Band 17 (704 - 716 MHz). Therefore, test data provided in this report covers Band 17 as well as Band 12. LTE Band 25 (1850 - 1915 MHz) overlaps the entire frequency range of LTE Band 2 (1850 - 1910 MHz). Therefore, test data provided in this report covers Band 2 as well as Band 25. LTE Band 66 (1710 - 1780 MHz) overlaps the entire frequency range of LTE Band 4 (1710 - 1755 MHz). Therefore, test data provided in this report covers Band 4 as well as Band 66.

Seriously, f*ck both Verizon and T-Mobile. Thankfully I'm starting my Cricket/AT&T service in a week so I'll be able to test if it can pick up and use Band 12/17. You happen to know of any app or way to force/limit the device to only using one specific LTE band? Thank you so much for linking to that thread for flashing these using LGUP. I'll make sure to follow it and to download the US996 (US Unlocked, not US Cellular) firmware and post a small update on my findings. Thank you so much for all the info. Really appreciate it.

While I've never tried this, have a look at this old thread on LTE band selection from a hidden menu. The dialer code differs by model, so for a VS995 it would be *#546368#*995# and for a US996 *#546368#*996#. The code works for my US996 and H918 on Oreo but not for my LS997 on Nougat (for which there is a separate APK file to access the hidden menu). There are lots of submenus and items in there, so be sure not to accidentally change settings that you're not supposed to.

If android 9 whats the battery backup (good/bad)
Does the android 9 has a darkmode
Does it brings back or activate the FM radio ?
Thanks

Android 8.
I know Android 9 does not have FM radio because Android 9 is only available for the Korean variant (F800) and it never had FM in the first place.

All of them seems to work fine.
Will this work in terms of flashing us unlocked firmware or my Verizon LG v20 (vs995) I rooted it successfully, but when I flash these firmware files, the phone is in a bootloop. US996 twrpable zips
