Oh sh*t...

I guess I lost my efs partition then...

I tried a bunch of stuff from your first post... sadly, I don't have an /OP/ directory at all... and when I try to force the mcfg mbn (from my sdcard lol, cauz my carrier is not provided in the us998 modem)

Edited a bunch of stuff in my build.prop to make it look more like the canadian one.. but it still doesn't work (even lost the volte option now in the mobile setting menu..)

Also, I tried to flash my canadian modem files... sadly.. the phone boot but the modem doesn't initialize at all... (no wifi and no mobile network)
[LG V30 Guides, News, & Discussion] seadersn:
aye, sh¡t... and there's no efs backup from your phone done / available as it sounds. you lost your IMEI too??

can you check the directory

/dev/block/bootdevices/by-name

and see if there's an OP "file"? eventually only the script which mounts it is broken. if I remember correctly there was a thread about regathering the IMEI or at least fixing some stuff on efs. maybe this helps you, unfort. I don't know where it was, you have to search yourself.

k, sleeping now, it's hard for me these days after my shoulder operation... hopefully we get your phone back running! I'm optimistic :) flashing a efs backup and changing the imei back to your original one for example. don't know if this is possible, but how often did I think "sh¡t, now it's over, phone's bricked" and then a solution appears out of nothing. you should've seen my face in the moment volte came.up on my phone xD xD xD

see you later :) be optimistic!
[LG V30 Guides, News, & Discussion] cloud1250000:
Oh sorry! I still got my efs partition.. I thought it would get overwritten when doing the frankenstein method.. But I guess not.. Is there any way I can debug why the modem doesnt work at all when flashing the canadian one while using the us998 system?
[LG V30 Guides, News, & Discussion] seadersn:
there is but I don't have it in mind atm :D it's explained here at xda somewhere, logcat and dmesg is used for that :good: can be that it is bands related? so you have to unlock bands in your modem settings? edit: most likely not as wifi is dead too...
[LG V30 Guides, News, & Discussion] DLS123:
I already tried to set IPMI with my data like IMSI@ims.mnc005.mcc226.3gppnetwork.org but IMS still don't register and the setting doesn't stick. it always reverts to a default like random_IMSI@mnc001.mcc001.3gppnetwork.org.

I also created the ims APN but it doesn't help with anything.

I'm still digging but so far I have no clue what's going on.
[LG V30 Guides, News, & Discussion] seadersn:
hmm, did you try configuring sip telephony? for o2 germany the registration looks like

country code + phone number @ telefonica.de = (for germany) 0049xxxxxxxxxxxxx@telefonica.de. have a look at /data/user_de/0/com.lge.ims/shared_prefs/impu_list.xml

(user_de: I don't know if this is indicating the language the rom uses? so for an english language build it can look like user_en? I don't know...).
[LG V30 Guides, News, & Discussion] INSANEMODE:
does this break safetynet?
[LG V30 Guides, News, & Discussion] seadersn:
nope. i've got magisk installed, and did some other edits in system partition and it's not failing :good:

rooting or unlocking itself can break it, of course. but there are ways to circumvent this breakage. so no disadvantages. it survives a firmware flash, too.
[LG V30 Guides, News, & Discussion] Panokiaran:
I didn't find the /op folder, what should I do?
[LG V30 Guides, News, & Discussion] seadersn:
maybe it's not there on your phone. your phone's model no.? is it present in this folder:

/dev/block/bootdevice/by-name

? if not, it's not there and maybe even no equivalent :(. do you find some of these files in your phone when searching, on other places (cust.prop, vo_config.xml e.g.)?
[LG V30 Guides, News, & Discussion] SGCMarkus:
/OP only exists on Open Market variants (US998 and H930), from what ive been told how it was on previous LG phones
[LG V30 Guides, News, & Discussion] seadersn:
yep, our beloved h932 e.g. doesn't have this one, too.
[LG V30 Guides, News, & Discussion] agpol07:
Hi,

I managed to get only volte to work. Any ideas why the vowifi doesn't appear anywhere in settings?

Thanks
[LG V30 Guides, News, & Discussion] seadersn:
which model do you have? h930 i think :) but no, i don't know this :( it isn't in the settings of the phone app? and you don't see it (with a third party dialer like google dialer magisk module (am using that)) in the secret menu too? (*#*#4636#*#*)?
[LG V30 Guides, News, & Discussion] agpol07:
I ticked all the options under *#546368#*930# > GPRI_Volte_VoWifi > UX, so now I have the menu options. I'll try to register now.. Thanks
[LG V30 Guides, News, & Discussion] agpol07:
hi, is there any way to reset the modem settings to default? it says that android.phone stopped working every 3 seconds and I can't setup anything..
[LG V30 Guides, News, & Discussion] seadersn:
jep, the exact path to the files you need to delete is

/data/user_de/0/com.lge.ims

do it via twrp filemanager, add a dalvik cache wipe and reboot to system :good: app name is LG IMS.
[LG V30 Guides, News, & Discussion] myb:
Hi !

Great work and thank you for the in detail guide !

I have a question and my question is more complex.

I own a H930 EU, stock rom, not unlocked, not rooted. If I unlock the phone and root it, do the modification for VoLTE/VoWifi to work, unroot, flash a stock kdz through modded LG UP and lock the phone back. Is there a way to tell that the phone was rooted and unlocked (in case) of a warranty situation, is there a counter à la Knox on Samsung or something to trip a protection system ?
[LG V30 Guides, News, & Discussion] seadersn:
there is a counter, you can get its status via bootloader and "fastboot getvar all". but as long as your device is fully stock and not unlocked / rooted, this should not be a problem when returning device to rma. should be safe to go this route.
[LG V30 Guides, News, & Discussion] Dizzyrul3z:
[MENTION=3138121]seadersn[/MENTION] You should made your own custom stock based rom with volte and vowifi working. This gonna be epic my friend :)
[LG V30 Guides, News, & Discussion] myb:
Digi mobil ?

[MENTION=3138121]seadersn[/MENTION]

Like DLS123 I did all the tweaks and tricks but still doesn't works, same results. No VoLte and no VoWifi working. I think we have the same provider and the same problem.
[LG V30 Guides, News, & Discussion] seadersn:
in /system/etc/

ike_conf.xml & mapcon.xml & apns_conf.xml

is even more to play with :good: maybe (i hope) this helps, like adding an IMS apn and remove ipv6? if done with editing, go into settings - network and reset your apn settings, then reboot.

but i don't think i will create a volte stock rom, sry :D because i think, that it mostly relies on OP partition. there's the possibility to edit the op image in linux, you have to ectract it first from stock rom's kdz and can thenount it rw and edit to your likes. and there's the QPST program from qualcomm, but this one is a bit tricky...

btw, ims isn't registered on my device too, but volte and vowifi works nevertheless :good: hint: some providers unfortunately don't support RCS anymore, try leaving everything RCS related out or even disable it.
[LG V30 Guides, News, & Discussion] B3311:
I wish I had the balls to try this:o
[LG V30 Guides, News, & Discussion] myb:
It' ok with double "mcfg_sw/" in the path ?
[LG V30 Guides, News, & Discussion] seadersn:
/firmware/image/modem_pr/mcfg/configs/mcfg_sw/generic_/joan_glo/eu/o2d/o2d/germany

that's the path for me :good:

edit: so, no, i've made a mistake in rhe OP, thanks ;)
[LG V30 Guides, News, & Discussion] tiamed:
Hi OP, I unlocked additional bands through qpst, how can I get LTE CA working for these bands?
[LG V30 Guides, News, & Discussion] seadersn:
don't know? never did this; what's CA? carrier aggregation? if it is, i would call the carrier for asking that, as far as i know it's a setting from their side.
[LG V30 Guides, News, & Discussion] Slarty73:
does anybody confirm if vowifi works in airplane mode? if yes could you please share your .mbn config or provide info about carrier/region and setting you use on v30, thanks a lot!
[LG V30 Guides, News, & Discussion] Ernesto0023:
I´ve got the H930 modell from an austrian provider (A1). Is there a possibility to activate VoLTE/VoWiFi on it?

On the virst view i didn´t find the mentioned OP-Folder but the mentioned OP-File.

In the hidden menu i have IMS Settings (but it says "not supported" when i click on it) and GPRI VoLTE/VoWiFi Settings.
[LG V30 Guides, News, & Discussion] SGCMarkus:
Ahh, a fellow Austrian, nice

I got my V30 from them too ^^

But sadly A1 doesnt allow the V30 to use VoLTE or VoWifi, only a selected few devices (List of devicest hey allow: https://www.a1.net/voice-plus )

The other carriers we have here are even worse .-.
[LG V30 Guides, News, & Discussion] Ernesto0023:
Yeah a fellow ;)

Hmm... they support the LG G7,LG Q7 plus, LG K10, LG K11 and in the hidden menu i saw VoLTE and VoWifi Settings and we have the prove here at xda that it should be possible with V30 Hardware but it still dont works?

Is it that complicate for a carrier to "allow" that?
[LG V30 Guides, News, & Discussion] seadersn:
if it's in your contract but they support different devices only, then pfeif drauf and trial ;) my opinion is that markus was/is to lazy to test :p :D i'm on o2, they're known for their volte dilemma, and they strictly said "no. not possible.", no matter if hotline or stores. and what's now? even flightmode wifi calling works. the entries for your provider have to be in these config files, you can have an additional look at /system/etc/telephony.xml, apns-conf.xml, evtl. spn-conf.xml, featureset.xml and festureset-open.xml, mapcon-conf.xml and ike-conf.xml. there's even more to try, but you should get it running with these only

easily

: *if* it's in your contract. there can be difficulties with multisims, but even that can be solved.

test it, pls :good: would be nice when they could be proven wrong.
[LG V30 Guides, News, & Discussion] SGCMarkus:
i might be lazy, but i tried this already. The provider needs to explicitly allow your IMEI basically (or just allow all). My OP2 also supported VoLTE, everyone was like ahh how nice, and here i was... nothing xD
[LG V30 Guides, News, & Discussion] Ernesto0023:
Youre right, i did :D Ok at least i didn´t end in a boot loop, but actually iam still disconected. But VoLTE activating is possible now in the Network Menu

A few things that aren´t 100% clear for me:

I inserted here my whole IMSI, what exactly do you mean with 5 or 10 numbers? My whole IMSI has 15 digits, which should i insert here? Should i leave there the "xx"?

Ok clear, but i have seen in this file there are the mentioned VoLTE Settings but then also VoWifi Options, Info Tags (of course without entries from my operator) so i added here also the same lines with my mcc and mnc.

Another Option here in this Info Tag is epdg_enable="0" -> i changed to "1".

I can see VoLTE in the Network Settings but couldnt figure out what you exactly mean with Phone Settings? (where both should be there)

Which Test Menu do you mean? I couldnt find "Load Preset Configuration" -> This is the point where i get stuck now.

Reboot still works but Icon still says iam disconected.

---EDIT:

Ok found that menu but still the same - i guess it wont work?

Should i try something or just undo everything?
[LG V30 Guides, News, & Discussion] seadersn:
you know how i meant that :D yep, some providers have their imei connected control, my guess for o2 is that they don't. i should ask them for that, i never did.

[MENTION=4539415]Ernesto0023[/MENTION] i'll answer all this a bit later, maybe in two hours, need a pc and a bit of free time for that ?
[LG V30 Guides, News, & Discussion] cloud1250000:

... :good:
[LG V30 Guides, News, & Discussion] Ernesto0023:
Thanks for your reply but ive already finished your tutorial without success - the phone seems to accept the changes but VoLTE stays disconnected.

I looked for the files youve mentioned but dont know what to try else. You have any ideas?

I fear the only thing i could try is to get in contact with my carrier and ask for it.
[LG V30 Guides, News, & Discussion] seadersn:
ims disconnected: where is it said? in ims settings or in phone settings via *#*#4636#*#*? the second method says "volte not available" too for me, but it's working and ims is registered.

when you call them, pls ask if they have imei controlled (phone dependant/connected) volte or if it's open. when it's open and even available, it should be possible to enable it. i hope you've done a op partition and system backup before further playing with it ;)
[LG V30 Guides, News, & Discussion] Ernesto0023:
I have that icon in statusbar activated from your tutorial (so its it should be from the ims settings), there its disconnected. How can i test if its working or not?

Of course i have a system backup but thanks for your advice :good:
[LG V30 Guides, News, & Discussion] seadersn:
testing would be via making a call when on lte and watch, if lte stays or it switches to hsdpa or even edge.

jep, that's the ims app status :( it will switch to another network then when placing a call.
[LG V30 Guides, News, & Discussion] Ernesto0023:
Ok good to know. Actually i restored my phone so the settings ive tried once are gone so i cant test if it stays on LTE.

Ive asked my carrier about this topic: Thread

Im waiting for the answer and then ill take a new try.
[LG V30 Guides, News, & Discussion] seadersn:
which sw do you have installed? i think h930 open eu latest = 21o? i would need some info from you, but i could provide you edited images (system and op) for testing this then. just gimme some time for that then.
[LG V30 Guides, News, & Discussion] SGCMarkus:
I already asked ([URL="https://www.a1community.net/mobile-telefonie-327/volte-auf-dem-lg-v30-250498]here[/URL]), back then not even 1 LG device was listed
[LG V30 Guides, News, & Discussion] Ernesto0023:
Yeah i already saw your post but as you said, at this time no LG Phone was listed. Im curious about their answer, lets wait - im afraid it will be a standard answer like if its not listed it wont work.

Actually im on 21a - Boombox V1.3 but i could try then with any (maybe Stock) ROM
[LG V30 Guides, News, & Discussion] Ernesto0023:
Good news :D

VoLTE should be open at A1 :good:
[LG V30 Guides, News, & Discussion] seadersn:
let's wait for final confirmation from an a1 moderator :D but sounds good in first place.

i'll pm you: do you have telegram installed? we could continue there then, my plan is to edit the op and system images with your data :good:

I recently purchased a new V 30+ from Wally World. Unlocked, rooted, and flashed vs996g. Everything is fine except VOWIFI. With my previous V30+ I was able to get VOWIFI working but with the new one, no luck. I have used Shortcut Master and gone into Verizon Hidden Menu and populated the VOWIFI toggle with my number, enabled VOWIFI in WIFI calling, LG IMS Provisioning, and Call services and still no luck. I get the VOWIFI enabled in Advanced calling, the VOWIFI Icon next to all my contacts, but when I go to make a call, it says WIFI Call for a couple of seconds and then the icon disappears before the call connects. I'm ready to give up and go back to my other V30+ and use this one as my backup, but I really wanted to use this one as my daily driver since it's brand new. Anyone have any suggestions?

Guys.. I have a little problem with this tutorial. I can't even complete second point, because my phone can't take permission to my computer.

My phone (H930) is rooted (Magisk 18) and has unlocked bootloader.

Here is a screenshot from terminal (Ubuntu 19): https://imgur.com/a/HaFQRvH

What am I doing wrong?

EDIT: phone firmware: V22j-EUR (with april security patch)
[LG V30 Guides, News, & Discussion] Krekos/CZ/:
This command isjust for Backup of the files. But if you want to do it, you can try to pack the files using some phone file manager or in TWRP.

The tutorial begins in part B: Main Part
[LG V30 Guides, News, & Discussion] SkeletMastrr:
Ahh, okay. I have 1 more question to you :D

In these files will I include words displayed after arrow? I did this, but in MCFG Bullet I have "Selected MBN file is: Not Set Yet". In first file I pasted the line from /firmware[...]. After few restarts it even changed to another one, than "not set yet"..

PS: The IMS isn't supported too...
[LG V30 Guides, News, & Discussion] Krekos/CZ/:
Doble check if you write correct path to persist.radio.buffet_mbn_file (prefixed with /firmware/...)

ps.: i just found that i lost my config after last update so i'll set it again following this guide and i'll let you know if i hit some trouble.

[MENTION=3138121]seadersn[/MENTION]

After trying get it working 4 Hours and differently theories.

I ask you how I get it working, I post some screenshots here, maybe you can say, if it's alright with them.

persist.radio.buffet_mbn_file?

After past

"/firmware/image/modem_pr/mcfg/configs/mcfg_sw/generic_/joan_glo/eu/eplus/epl/germany/mcfg_sw.mbn"

He always show me result like in the attached screenshot, the same result I get in MCFG Buffet Option in Hidden Menu

Is my carrier_code.xml alright?

The last line I add because at the beginning there was no IMEI.

I only get the option VoLTE in my Mobile Settings, it's doesn't matter if a active all settings in IMS, after a reboot they uncheck them self. Only VoLTE stays

I'm confused about my provider is he now calling eplus or epl, I tried some different combination but with no success.

My Provider is O2, my Netz is Ay Yildiz.
[LG V30 Guides, News, & Discussion] seadersn:
is this urgent anymore?
[LG V30 Guides, News, & Discussion] Nemeziz 56th:
It is, a second attempt don't bring any success..
[LG V30 Guides, News, & Discussion] seadersn:
this is a tricky situation, because from my knowledge the former eplus customers have other contracts than the o2 customers, with other options enabled and volte is one of them: and the resellers have again other options. it really can be that this won't work, but for now mnc and mcc are taken from your phones infos and are correct? try cutting down the imsi in the xml to 26207xxxx first, for the rest i need a pc and xml file. we can continue this on sunday, i'm at home then and have access to my (not fully ready atm, but sufficient for that) computer :good:
[LG V30 Guides, News, & Discussion] Nemeziz 56th:
MNC & MCC are correct.

Let's continue this on Sunday. Thanks
[LG V30 Guides, News, & Discussion] seadersn:
after a bit of reading it looks like most of resold mobile lines from different providers using o²'s net don't contain extras like volte. but it's worth a try anyway, it's maybe really just a config thingy. hopefully. i would need some extra data for which i would contact you in the coming days. let's try it ;) maybe we get it. it's a nice feature and almost a must have: at least, when you had it once you won't miss it anymore :good: doesn't help, but maybe motivates for more power / nerves being invested :D

Hi, a few months back, after Pie release I successfully managed to get it working on H930. But after todays update which fixed ram management I'm not able to do it again... What text editor/ file manager are you using for creating new files like you do - "Now navigate to the folder "/data/property". There should be three files we need. If they are not there, create them with root:root, 0600 and following content pls:

persist.radio.buffet_mbn_file => the long path you copied before

persist.radio.buffet_enable => enable

persist.radio.sw_mbn_update => 1" "

My fm do not let me create these files with root privileges. and I have tried more than one root browser.

i'm using bought version of root explorer or QuickEdit Pro with root rights :)
[LG V30 Guides, News, & Discussion] Zoki88:
Is this method making IMS status from not registered to registered? Or this method is only for enabling VoLTE and VoWifi? Asking, because i don't need those two(neither my carrier doesn't support them), i need Video Calling(that's the only thing my carrier support): https://imgur.com/asOHU3d

Edit: i just read whole guide, and checked for files on my phone, but i don't have:

1. /OP/client_id.xml

2. /OP/OPEN_AME_DS/config/carrier_code.xml

3. /OP/OPEN_AME_DS/config/com.lge.ims.rcs.xml

5. /OP/OPEN_AME_DS/config/vo_config.xml

So only thing that i have is 4. /OP/OPEN_AME_DS/config/featureset.xml

i also copied MNC, MCC, IMSI from hidden menu, and path for my provider. What should i do? Can this method work if i have LG H930DS(V30+), which have OPEN_AME_DS firmware (this AME firmware stands for United Arab Emirates), which i'm using it in Europe carrier, and i'm living in Europe? Hope to get answer soon :)
