noone...? come on, this is a 3-5 minutes job :D deleting takes only 2 secs as i know now... but w/o these files no modem config is possible, phone could be useless on next reboot. so, pls :) pls...

btw: no personal data stored in these directories. there are only config files for different operators inside, nothing else. mcfg_sw.mbn files, you can google for their function and have a look at them on your phone. easiest way for zipping them would be "root explorer", it offers this function, and tar compressing too. hm, when i think about it, tar would be better format :)
[LG V30 Questions & Answers] ChazzMatt:
I would be glad to help but I don't have H930...
[LG V30 Questions & Answers] seadersn:
hmm, which one do you own then...? maybe worth a try to have a look at the files from a different phone as long as it's native open and an EU one. and: I've seen you're a really helpful person, a superb contributor, one of the best in v30 forums :) thx for that! :thumbsup:
[LG V30 Questions & Answers] myb:
H930 here, but it's not rooted.
[LG V30 Questions & Answers] seadersn:
grmpf, there's no way then to access these files, unfortunately :( but thx anyway :)

Looks like you need to get busy this weekend! ;) Just so you actually own your phone.
[LG V30 Questions & Answers] Krekos/CZ/:
I have Rooted H930. But how can i access these files?? i can't see them in TWRP.
[LG V30 Questions & Answers] seadersn:
wonderful!! if we get this working you're my hero :D ;)

in twrp there's no way to get them, this has to be done in fully booted android system. you have got terminal emulator app installed? the command would be

tar -czf /sdcard/modem.tar.gz /firmware/image/modem_pr/mcfg/configs

the resulting file can be found in root dir of sdcard then. maybe it's small enough so you can attach it on your answering post, otherwise maybe using google drive or androidfilehost is needed.
[LG V30 Questions & Answers] seadersn:
double post, sry...
[LG V30 Questions & Answers] Krekos/CZ/:
It's strange but i cannot compress these files. It always tell me, i dont have privilegies for that. I try severel Emulators. I also try TotalCommander App with root privilegies, and copy the files manually, but i ended with error aswell.
[LG V30 Questions & Answers] seadersn:
ouch... did you type "su" to give the terminal emulator root privileges before trying?
[LG V30 Questions & Answers] Krekos/CZ/:
I got it! :D I finally found emulator which compress the files. i dont know why previous apps didnt work but w/e.

Here it is: https://goo.gl/Qk293b
[LG V30 Questions & Answers] seadersn:
yay!!!!! it worked, the files are back! THANK YOU VERY VERY MUCH!!! you saved my h930 :) thanks again! :good::highfive::victory:
[LG V30 Questions & Answers] seadersn:
hmm, is it okay for you when i attach this zip on the first post with big fat credits to you? maybe someone else needs these mbn files for his SD835 device at some time?
[LG V30 Questions & Answers] Krekos/CZ/:
I have no problem with it. :) you can attach it.
[LG V30 Questions & Answers] seadersn:
thx, again :)
[LG V30 Questions & Answers] seadersn:
...aaaand: volte (and vowifi; don't know for sure about viwifi and vt/vilte. sms over wifi/volte needs to be tested too) is up and running! LoL... o2 wasn't able to help me in four service hotline sessions and two visits in their store. really funny as they told me every time "absolutely no way, sry. we can't do this (send some infos or activate volte in account [was already activated, it worked all the time with my s7flat]), we can't do that (flash something to get this working) and so on. k, this took me an serious amount of time my kids and wife weren't really happy and proud of, but hey, there are priorities, or not? hrhr...

is there a need for a guide for everyone? maybe I get a guide up and running. problem for now is, I don't know for sure which edits are really needed and essential. this will be a guide we need to work out all together to finally see which steps are necessary for a newbie and starter. let's see, would take some time but should be possible. when five ppls in this thread are telling "yes we want this guide, let's do this together!" then I'll do it :D

would've not been possible w/o the help from [MENTION=8036169]Krekos/CZ/[/MENTION] :) I'm really happy he helped out! :good:
[LG V30 Questions & Answers] Krekos/CZ/:
I would like to try this feature :) and you're welcome.
[LG V30 Questions & Answers] Dizzyrul3z:
Nice one. So vollte will be available for every gsm operator on stock rooted rom?
[LG V30 Questions & Answers] seadersn:
after some configuration, which is individual for every provider (so an all-in-one allround patch suiting everyone isn't really possible unfortunately), it's possible to use vowifi/volte with default h930 eu open /global-com stock rom (root needed!), jep :)

k, we have two ppls for now :D

upload via mobile site to xda directly isn't possible atm? neither with mobile android client nor desktop android client.
[LG V30 Questions & Answers] stuclark:
Really interested in this for O2 and EE in the UK on both the V30 and G7 (I'm presuming the same methods will work on both, even if different files are needed)
[LG V30 Questions & Answers] seadersn:
it's perfect ... I missed it!

you can start with loading your mbn file for o2 uk. you can have a look into the zip to determine the path to the location of your file needed. then use a file manager with root priv's to edit the file

/data/property/persist.radio.buffet_mbn_file

and put this path inside, including mcfg_sw.mbn. so for o2 germany it reads

/firmware/image/modem_pr/mcfg/configs/mcfg_sw/generic_/joan_glo/eu/o2d/o2d/germany/mcfg_sw.mbn

then edit the file

/data/property/persist.radio.buffet_enable

and type inside "enable" (w/o quotes). reboot and check with *#546368#*930# => field test => scroll down to mcfg buffet and check if the file is loaded.

let's start :)
[LG V30 Questions & Answers] seadersn:
ok. now we have the corresponding file loaded we first gather some info about our sim card, we need it later for further editing files. this will be a little bit tricky for me do determine which files are really needed and which ones are only a "side effect", as I edited just everything which came to my mind, just to be sure to give the ROM and the IMS service all the info it needs. :D

in service menu (*#546368#*930#) hop over again to field test and tap the point "sim info". write down the mcc and mnc (this is your operator code. with this one can load config files and point the ims service into the right direction). for o2 DE this is mcc 262 and mnc 07, together it reads 26207. write down IMSI too, it will be needed for registration stuff. we also need to alter some files later which are holding some info but are looking misconfigured (or better: missing the correct info), so we need to put these infos into these files manually.

k, next step maybe follows this evening (living in Germany).

next step will be editing some files in /OP folder. you should back it up, zip or tar the complete folder.

cya l8r :)
[LG V30 Questions & Answers] Krekos/CZ/:
Hmm okay i don't know what i'm doing wrong. i created file :

/data/property/persist.radio.buffet_mbn_file

with this content:

/firmware/image/modem_pr/mcfg/configs/mcfg_sw/generic_/joan_glo/eu/vodafone/vdz/czechrep/mcfg_sw.mbn

then i created file:

/data/property/persist.radio.buffet_enable

and type enable to it.

but if i reboot phone and look to the FieldTest, No file was loaded.
[LG V30 Questions & Answers] seadersn:
is there a file called

persist.radio.sw_mbn_update

? if yes, put a "1" inside it, w/o quotes, as always :) if not, create it pls and give correct permissions.

you need to give correct permissions to these files too. thought they are present already as they were on my phone; they are created via another xml edit, i think.

permissions are:

owner: root

group: root

permissions: 0600 (read and write only for owner)

and: are the persist files you created there anymore or are they deleted?
[LG V30 Questions & Answers] Krekos/CZ/:
Of course ... permissions was the problem ... Now it's loaded
[LG V30 Questions & Answers] seadersn:
ok. now you can try two things for the first time: a) if there are any VoLTE or VoWiFi switches available in settings (calling settings or network settings) already and b) if IMS settings (field test => IMS setting) in hiddenmenu are starting or if there is an error, warning or sth. else.
[LG V30 Questions & Answers] Krekos/CZ/:
There are no switch for VoLTE and in hidden menu, when i open IMS it show 'NotSupported'
[LG V30 Questions & Answers] seadersn:
k, we can continue in roundabout an hour or two, I have visitors at the moment.
[LG V30 Questions & Answers] seadersn:
it's a little bit more now ;) pls, do yourself a favor and make a full backup incl. efs in case sth. is going wrong. zip or tar the /OP folder too and save it.

we need to point your ROM in the right direction: localizing it and giving the exact operator infos. have a check of following files and the should-be's; if sth. isn't as we need it, you'd need the info from sim info screen in hiddenmenu.

/OP/client_id.xml:

is your mcc and mnc inside? if not, copy and paste a line and edit it so it suits your mcc and mnc.

/OP/OPEN_EU/config/carrier_code.xml:

your operator should be inside, i think i saw it; if not, copy and paste a line and edit the necessary entries to match your operator

/OP/OPEN_EU/cust.prop:

ro.lge.capp_cupss.rootdir=/OP/OPEN_EU

ro.build.target_operator=OPEN

ro.build.target_country=EU

ro.build.target_region=EU

ro.product.locale.region=CZ

ro.product.locale.language=cz

ro.lge.cupssgroup=GLOBAL-COM

ro.lge.opensw=EUR-XX

ro.lge.radio_mcfg=1

persist.lg.ims.volte_open=1

/OP/OPEN_EU/config/com.lge.ims.rcs.xml

create an entry with your operator details, only VDF (vodafone) is in this list

/OP/OPEN_EU/config/featureset.xml:

change every item which is "false" to "true"

/OP/OPEN_EU/config/vo_config.xml:

most likely you need to create an entry for your operator with mnc and mcc. do this and change both variables to "1":

<info mcc="230" mnc="02"><!-- O2C -->
<prop
support_volte="1"
support_vt="1"
/>
</info>

/system/build.prop:

change your ro.product.locale to match your country, for you it's cz-CZ

ro.lge.capp_cupss.rootdir=/OP

ro.lge.capp_cupss.op.dir=/OP

and finally reboot :)

after that have a check again regarding IMS Setting :good: and check the props you edited with terminal emulator and getprop pls :)
[LG V30 Questions & Answers] seadersn:
good morning :D

next thing should be IMS Setting configuration. These settings are reachable via above mentioned menu entry and via field test => GPRI VoLTE/WiFi (this is a setting menu you also find in IMS Setting, it's included in there). I hope I picked out the important & relevant edits in my post above, there were much more... mapcon, ike and stuff... but we'll see ;)

IF

IMS Setting is already working, you can try following menu point and see if VoLTE already works: IMS Setting => Test => Load Preset Configuration => Initialize configuration.
[LG V30 Questions & Answers] seadersn:
if questions arise, pls ask! I rely a bit on your experience now, since my VoLTE etc. is running :D feedback is needed for finding the really relevant files and edits :) when Krekos/CZ/ is succesful and volte etc. is available for him, I can think about rewriting all the necessary stuff and do a guide thread then. but first some 'unhappy' info: I need to go to hospital on coming monday, my shoulder is defective after an accident and the metal inside needs to be removed. I'll be a little bit handicapped then, and stoned from the medication xD so a full guide thread would arise earliest in 10 days I think. let's wait what the poll says.
[LG V30 Questions & Answers] seadersn:
did someone already do all these edits and can tell me what's accessible and what's not, how far we went with these edits? mainly: if the volte/viwifi switches are available in phone and network settings, or (even better) if IMS Setting in hiddenmenu (*#546368#*930#) doesn't tell "not supported" anymore but instead opens? would be nice to know for me ;)

with these modem config files (and some additional files which needs copying onto the phone) we should be able to get volte for every operator who has a config file available in this zip even on tcom phones. so one of the next steps could be trying getting volte on a tcom phone, with an operator which isn't included in tcom's firmware.
[LG V30 Questions & Answers] Krekos/CZ/:
Sorry i was busy last days .... i will try it now.

So file: /data/property/client_id.xml i dont have. Can you send me what content should be in it?

And for file: com.lge.ims.rcs.xml where i can find prefix for my operator?
[LG V30 Questions & Answers] seadersn:
oops, there's the first mistake in my post: it's /op/client_id.xml, sry :D have a look at it and search for your mnc and mcc or for the term "o2c" (presuming you're living in czech as your username contains it).

how is your com.lge.ics.rcs.xml.looking? are there entries for vdf only or other entries too? I copied a line with vdf entries, pasted it and edited the corresponding values, so.it looks for me like

<siminfo mcc="262" mnc="07" operator="O2D" country="DE" prefix="49"/>

you need the info from sim info screen in hiddenmenu :)
[LG V30 Questions & Answers] Krekos/CZ/:
in com..lge.ics.rcs.xml i have only VDF entries. So i add this line:

<siminfo mcc="230" mnc="03" operator="VDZ" country="CZ" prefix="??"/>

and i dont know what to write into prefix.

but i upload other files to phone and reboot. After that IMS section in hidden menu is accesible
[LG V30 Questions & Answers] seadersn:
420

change operator to "O2C" too pls :)
[LG V30 Questions & Answers] seadersn:
all right, give me half an our, we're eating ;)

you can try if

IMS Setting => Test => Load Preset Configuration => Initialize configuration

already enables volte, after changing do a reboot :)
[LG V30 Questions & Answers] Krekos/CZ/:
420 .... phone number prefix ..... why i forget on it .... THX :D
[LG V30 Questions & Answers] seadersn:
upload files? which ones from where? or did you mean edit? would be interesting which files it were, if you really uploaded sth to your phone :) (btw, sth means something for me, just too lazy to write full)
[LG V30 Questions & Answers] Krekos/CZ/:
yeah, i mean edit ... Because i edit files on PC then i upload them back to phone ...
[LG V30 Questions & Answers] seadersn:
i'm doing all the edits on phone itself. which editor are you using? notepad++ is very good for editing linux files. when you do this with windows editor for example, the format of the file could break and isn't readable anymore, resulting in errors. and be careful about the file owner and permissions. all these problems don't exist when editing files on phone :D

if you're on linux, only the file owner and the permissions need to be observed.
[LG V30 Questions & Answers] Krekos/CZ/:
I edit files in Sublime. I set lineEndings to Unix types. and i check all permissions after upload.

Which app you using to edit files on phone??
[LG V30 Questions & Answers] seadersn:
i've bought root explorer a long time ago, it includes everything i need: zip/tar, edit, show text, permission and owner setting etc :)
[LG V30 Questions & Answers] Krekos/CZ/:
OK i made IMS initialization. what next? or where to check, if all is OK.
[LG V30 Questions & Answers] seadersn:
k, we're trying now to configure your IMS service. first we let the IMS setting show a symbol in statusbar, this way we don't need to dial the hiddenmenu code everytime. to do this go into "Test" in IMS settings and activate "show icon". after that you can go to the GPRI volte/wifi setting inside IMS settings and activate volte and vowifi. then do a reboot and press the thumbs: maybe this was it and your volte is running! maybe...
[LG V30 Questions & Answers] seadersn:
for checking if volte is up you can have a look into "Debug Screen" => "VoLTE Debug Screen" inside IMS setting.
[LG V30 Questions & Answers] Krekos/CZ/:
OK. after reboot it show VoLTE/SMS Connected. and on Debug screen:

NetworkMode: LTE

Status: Enable
[LG V30 Questions & Answers] seadersn:
you're done :)
[LG V30 Questions & Answers] seadersn:
when you place a call to someone now, LTE should stay active and it should connect to your calling partner really fast, like 1 to 5 seconds.
[LG V30 Questions & Answers] Krekos/CZ/:
Oh, Thank you :)
[LG V30 Questions & Answers] seadersn:
thanks, too :good: test it some days and pls give feedback, especially when errors appear. maybe further settings are required.
[LG V30 Questions & Answers] Krekos/CZ/:
It seams that everything is ok. I tried to call my sister and nothing went wrong.
[LG V30 Questions & Answers] seadersn:
all right, sounds good :good: is wifi calling active?

you can turn on volte and vowifi symbols, which are then on the right side of statusbar near the clock, in IMS settings => GPRI volte vowifi => Registration => VoLTE => Indicate VoLTE. the same for wifi and then you can disable statusbar icon via test => show icon.
[LG V30 Questions & Answers] Krekos/CZ/:
I already turned on VoLTE indication :) But don't know how to test VoWifi
[LG V30 Questions & Answers] seadersn:
switches in calling settings and network settings are on? switch on wifi, when the test statusbar icon is on, you will see if it connects and then place a call again :good: you can even switch on flightmode and then wifi and place a call. but i think, you have to activate wifi calling in flightmode first somewhere in ims settings menu.
[LG V30 Questions & Answers] Krekos/CZ/:
i see only VoLTE switch. In IMS settings i enabled FlightMode calls, but it seams i can't make a VoWifi calls.

---------- Post added at 11:34 AM ---------- Previous post was at 11:32 AM ----------

hmm. in IMS setting VoWIFI is disbled. Bud when i enable it and reboot phone is disabled again.
[LG V30 Questions & Answers] seadersn:
k, give me a sec.
[LG V30 Questions & Answers] Krekos/CZ/:
Also VoLTE swtitch in settings disapeard after reboot (But VoLTE is stil enabled and OK)
[LG V30 Questions & Answers] seadersn:
it's in IMS settings => GPRI volte vowifi => Registration => VoWiFi => Flight Mode.

once it's registered you can stop thinking about it. it won't disable by itself, only when your provider does it.
[LG V30 Questions & Answers] Krekos/CZ/:
Ok i add entry to vo_config.xml to VoWifi section and now is VoWifi switch in settings.

AAAnd VoWifi works!! :D
[LG V30 Questions & Answers] seadersn:
ah, ok, you forgot this one :D all right, when xda wouldn't be slightly buggy atm i could've uploaded a proving pic here, but....
[LG V30 Questions & Answers] seadersn:
yeah, i like it xD received the first call with the config flight mode on via vowifi :good:
[LG V30 Questions & Answers] seadersn:
all right, one more confirmation that this is the key to get volte running and i'm doing a full guide thread then. maybe a flashable zip is possible too. but i need one more person to clarify that these steps /Krekos/CZ/ and me worked through are enough to get it working. i guess, the mapcon and ike and other edits aren't really necessary, or necessary only if there is a completely unknown provider.
[LG V30 Questions & Answers] seadersn:
I'm doing the guide atm, it should be enough info and I need sth to do as I'm getting nervous because of tomorrow LoL expect it in roundabout half an hour in the guides section :good:
[LG V30 Questions & Answers] seadersn:
k, it's up :) maybe it's a little bit "noob-unfriendly", but this will change with time. it's more of a dev thread right now, I hope we can collect some more infos on that :good:
[LG V30 Questions & Answers] stuclark:
Using your guide as a basis, I've been able to get VoLTE (and maybe VoWiFi - just seen where I went wrong) working on two different UK networks... On the LG G7 Thinq!

On that phone there are a lot of missing files, including whole directories where the .mbn info should be, but it seems the only bit that needs changing is the vo.config.xml to at least get VoLTE and VoWiFi enabled.

The settings are broken into two sections within the file on the G7, which is how I missed the VoWiFi settings on my first try.

... Not really surprisingly, the changes aren't persistent across a firmware upgrade (i tried from v10b to v10f), so maybe that's a next step to investigate, as is how to make the changes then remove root & relock bootloader (without a factory reset) to re-enable Google Pay etc.

[Sony Xperia XA2 Questions & Answers] digitaloutsider:
I'm guessing I'm probably one of the few people out there using the Xperia XA2 on Verizon. My OG Pixel gave up the ghost yesterday so I picked up one of these XA2s because the price seemed hard to beat. The XA2 is certified under Verizon's Open Development program and functions as an LTE-Only device, with no CDMA connectivity.

Anyway, my question is if there is any way to get the WiFi Calling to actually work on the handset. I can confirm that the feature is still provisioned on my account, but the phone itself doesn't seem to pick them up. There is no option to enable it in the Phone application. If I go into Phone Info (*#*#4636#*#*), there are toggles for both Video Calling and WiFi Calling, but they are greyed out. I really do like the phone, especially for the price, but losing WiFi Calling might be a dealbreaker. Has anyone had any luck here?

Factory software, 50.1.A.12.9.
[Sony Xperia XA2 Questions & Answers] Meloferz:
I recommend you to update to the latest version of the firmware, because after Verizon announced that XA2 is supported to their network, a special update was made for the USA variant of the XA2. Also verify if you have the USA firmware
[Sony Xperia XA2 Questions & Answers] digitaloutsider:
Hey, sorry for the late response. Thanks for the reply. I am on the latest US firmware, which was required to get VZW compatibility in the first place. Without it, it wouldn't even connect.

No WiFi calling option anywhere, though. Kind of a bummer. Regardless, I've kept the phone. Everything else works pretty much the way I want it to, and fortunately for now I live in a really good service area.
