There are a lot of custom dialer skins and they work well on CDMA phones. I have created a couple and posted them there.
[Mogul, XV6800 ROM Development] auto3251:
Just looked through that thread, it's not skins i want, it's the actual dialer cab. the stock one that comes with dcd 312 i'm having pop up issues with. There is one cab dialer on that thread but it's for gsm.

Prep: just because it's not uploaded here doesn't mean no one has it, pretty sure it can be extracted from a cdma touch (someone correct me if i'm wrong).
[Mogul, XV6800 ROM Development] prepsssuck:
Thats why I suggested searching google or another forum...I would even suggest strolling thru another phones forum on this site...the built-in search function in this forum sucks IMHO
[Mogul, XV6800 ROM Development] prepsssuck:

[Mogul, XV6800 ROM Development] c@rL0$:
It is there you just haven't searched profoundly.

Clue "post 233" on that page.
[Mogul, XV6800 ROM Development] c@rL0$:
Isn't this the one that breaks the EPST functionality? (GSM Version)

Or is this a newer one?
[Mogul, XV6800 ROM Development] auto3251:
I was using that one until someone told me it'll mess up things, so i did a hard reset.

with that one ##778 still showed information, * numbers still worked, and speed dial worked. speed dial = smart dialing?

is there another way i can try if 911 works, besides actually dialing it?

if all that works, should i be able to use it, or could problems still arise later?
[Mogul, XV6800 ROM Development] gc14:
This dialer is not a CDMA dialer and indeed breaks ## codes and 911.

I don't know how your ## codes and 911 worked with that dialer, because it absolutely doesn't on my phone and shouldn't on anyone's CDMA phone.
[Mogul, XV6800 ROM Development] c@rL0$:
I directed you to the Mogul Big Button dialer, you can take a pick at which dialer to chose from.
[Mogul, XV6800 ROM Development] auto3251:
him is me:)

the one you directed me to was the one i tried before, and it doesn't show up correctly. the number pad is all jammed together, and the parts of the contact list leaks through the dial pad. i think this is because you said on post 233 that you need to uninstall the old dialer, which i can't, because it's the stock one that comes with dcd312.

so i should be safe with that retouched wizard 2?
[Mogul, XV6800 ROM Development] prepsssuck:
"This dialer is not a CDMA dialer and indeed breaks ## codes and 911."

Never had to use those so thats probly why I didnt have any problems with that dailer. There are tons of dailers out there...about 20 different iphone and diamond varations to choose from..and thats a start...Cant find a cdma touch though
[Mogul, XV6800 ROM Development] c@rL0$:
Dude, just install both of these CAB's and you should be good.

The Mogul Big Button Dialer CAB is the Actual Dialer and the Touch CAB is to skin the dialer to look like a Touch Dialer.

There are tons of dialer variations out there. Feel free to use the SEARCH function or Google to help you out first if you need anything.:rolleyes:
[Mogul, XV6800 ROM Development] gc14:
No, this dialer is indeed the same GSM dialer and DOES break functionality.
[Mogul, XV6800 ROM Development] prepsssuck:
Yeah read up a little on it and it also creates problems with 911 gps function so wouldnt use just in case of one of those emergencies
[Mogul, XV6800 ROM Development] auto3251:
just tried it, part of the call history list still leaks through to the dailer, button 3 6 9 and * are pictures of a back button, and 3 call history. what's going on?
[Mogul, XV6800 ROM Development] c@rL0$:
Before you installed this dialer did you remove any other previous dialers?

Did you soft reset after installing both cabs?

I can't replicate your issues.

Mine looks perfectly fine and I have been using this dialer for a while already.
[Mogul, XV6800 ROM Development] auto3251:
I don't know how to remove the previous dialer, it's the stock one that comes with dcd 312 rom.
[Mogul, XV6800 ROM Development] azclown:
Install this dialer.... EPST works, I just verified it on my phone....
[Mogul, XV6800 ROM Development] auto3251:
having the same problem installing this one as if i did with the big button dialer, the skin is all messed up, i think this is due to the fact that i still have the stock one from dcd312, and i can't uninstall it.
[Mogul, XV6800 ROM Development] htc.user:
all grey and white just like dcd's touch-themed dialer

i have used nearly all the dialers posted, and even created my own using the Tdial designer and though it certainly creates the cab and makes the buttons look like the touch, it never successfully makes the buttons' background grey/white...in other words, on my vogue, the dialer is perfect (of course), but i have to install dcd's rom in order to make my titan's dialer a nearly perfect match.

the background after either install [the mogul_big_button_dialer.cab, software reboot + touch.cab, software reboot] or [BlueFrog_Touch_Dialer.cab, software reboot] = blue background on dialer (smartdial entries as well as buttons such as "speaker on/off", "mute", "note", "contacts", "talk", and "end").

i have searched the windows directory as well as the PhoneSkin folder for the exact picture files that i need to replace in order to get a skin exactly like dcd's rom...in fact, i have installed dcd's roms for the sole purpose of finding the picture files to make them exactly like my vogue...to no avail. sometimes i end up making the numbers disappear and i have to start over again (hard reset). which ones do i have to replace?

i am not talking about the voicemail icon. the bluefrog method does it automatically, the two-cab method involves an easy registry change listed everywhere.

if anyone knows the answer as to why i get a blue background for some of the aspects of the touch dialer skin using the two aforementioned methods on a titan, please explain. why would they want the blue? it looks incomplete.:confused:
[LG V40 Questions & Answers] AzzKickah:
Hello,

I have a LM-V409N here. It has some Korean bloatware but worse than that, even though the phone is set to English, a lot of things are still in Korean. For example an available software update description is in Korean. Buttons in the phone app show Korean text, etc.

Can I flash a European firmware on to this model? Will that 'just work'?

I hope someone can help me with this.

Thank you,
[LG V40 Questions & Answers] neocyke:
Rooted? you won't get far otherwise. Had the same problem on my korean G5.

On a rooted device though, you can edit the build.prop locale to your native region to turn off the korean elements of the UI and obviously remove the bloat.

some of the bloat can be disabled even if uninstall isn't allowed. Carrier specific ones can't unfortunately.

Flashing wise, iirc that's a no go as it will break radio. No signal afterwards. At least that was the problem on the V35.
[LG V40 Questions & Answers] AzzKickah:
Thank you so much for your reply. This makes me worry a bit less :)

No I don't have it rooted (yet). I will go figure out how to do that for this phone model and then if I can't find out how to do the build.prop changes I will come back here to ask for help :)

Do you have any idea why WiFi HotSpot is not working properly? Laptops and other phones just don't see the SSID and when trying to setup a 5GHz hotspot, the slider hangs when you turn it on (turns gray and freezes) and you have to reboot the phone to get it enabled again. But it will only turn on when on 2.4GHz.

If I can get all the Korean stuff to disappear, flashing won't be necessary anymore :) So let me get to finding that out!

Let's first see if flashing fixes anything.

Thank you so much once again!

Edit: Come to think of it, when I turn on the phone it shows an SK Telecom animation and sound (some Korean carrier I guess) and I would like that removed as well..

I guess the only way to get that removed is to flash another firmware? Would you know a firmware version for this LM-V409N which is just 'LG original' without any carrier/provider customization?

Thank you!

Edit2: OK, I found out how I can flash a stock firmware using the LGUP tool. However, this fails at the beginning of the process because of an 'Initialize' error.

I suspect I need the device to be rooted before flashing..? I could find how to flash pretty easily, but how to root..?

Can anyone point me to a guide for rooting the V40?

Thanks!
[LG V40 Questions & Answers] Inerent:
No, you don't need root. Just search here on xda for crossflash word. In the g7 forum I have made an tutorial. You will need lg drivers, com port, lg up and common. DLL for v40. For g7 it works like a charm. Be sure to check and compare GSM bands from Korea to EU. For g7 they was the same.
[LG V40 Questions & Answers] AzzKickah:
OK, did all that. LGUP starts up, detects my LM-V409N correctly.

I select the KDZ file, set it to UPGRADE and click START.

Now it gives me the error 'LGUP Framework must be 1.16'. I have 1.14 apparently and I can't find 1.16 anywhere.

I read something about "If you do have some knowledge to bypass the LGUP Version Check on this DLL, then You can sideload kdz firmware onto your LG V40 ThinQ with LGUP 1.14." on this site: https://www.mylgphones.com/lgup-dll-for-lg-v40-thinq-version1-9-39-7.html

But again, I can't find anything about how to bypass that version check.

I tried with LGUP_common.dll versions 1.9.39.7 and 1.0.39.10. Both same result (need 1.16).

Also tried with 0.0.3.23 but that one gives the "Initialize" error after clicking START.

Any other tips or tricks you can suggest?

Thank you,
[LG V40 Questions & Answers] Inerent:
Hello.

I told you to look in g7 forum for crossflash. You will need lg up 1.15 and follow the exact steps. Beware it may brick your device, so I'm not responsible.

Link here https://xdaforums.com/lg-g7-thinq/how-to/cross-flash-oreo-pie-firmwares-lg-g7-g7-t3915303/amp/

Warning!!! Pay attention not to download the common. DLL from there as it is for lg g7. You must download for your v40. Also for your firmware. Also you will loose your data, so backup first if you have important files, sms, etc.
[LG V40 Questions & Answers] AzzKickah:
OK so for my clarification, this method is how to bypass the version check? (If yes, I will go try this).

Or is this a separate method? (If it is separate, I'm afraid to brick it and I will not try it).

Thank you so much for your help. It really is very much appreciated.
[LG V40 Questions & Answers] Inerent:
Yes, this is for bypassing the obsolete lg up 1.14.

But 1.15 will not work if you open it, it will ask you for developer user and password. But there is a hack with using cmd line. Follow my steps.

I repeat again, if there is a working DLL for lg v40 and if 40 supports crossflashing (highly it does) then you're good to go. Don't forget to check what is your com port when your v40 is connected in download mode.

If you're connected to a USB 3.0 port and have quality USB c cable, it should install it in less than 1 minute

---------- Post added at 11:47 AM ---------- Previous post was at 11:39 AM ----------

Here is a little tutorial for V40

Easy commands for this new LGUP v1.15.06

If using powershell from win10:

1. Install USB drivers and put V40 in download mode - connect it to USB cable then go and check your COM port in windows device manger

2. Open powershell from C:\Program Files (x86)\LG Electronics\LGUP (shift + right mouse) and type cmd and hit enter.

3. Type this command: lgup_cmd.exe comX "C:\Program Files (x86)\LG Electronics\LGUP\model\common\LGUP_Common.dll" "(path to your kdz firmware)"

Example: (if your phone is under com5 and your kdz is located in D:\ and has this name XXX.kdz)

lgup_cmd.exe com5 "C:\Program Files (x86)\LG Electronics\LGUP\model\common\LGUP_Common.dll" "D:\XXX.kdz"

[LG V40 Questions & Answers] Inerent:
So you didn't flashed the European firmware? :confused:
[LG V40 Questions & Answers] AzzKickah:
No I didn't. Neocyke told me that radio wouldn't work that way so that would have been useless then. This is the post: https://xdaforums.com/showpost.php?p=80177222&postcount=2

Or did he mean FM Radio......? Because I could live without FM Radio.

The one I did flash is still Korean, but it has no carrier customization. No cellular provider specific apps, no Korean company logo's at startup.

Only thing I noticed is that there still are Korean characters showing right below the numbers in the phone dialer app. But it also shows ABC, DEF, etc.

Oh, and a second clock showing Korean time on the lock screen :silly: which I can't find out how to turn off :eek:
[LG V40 Questions & Answers] Inerent:
I also have that clock on my V50.

For me it worked with my g7+ Hong Kong international to European and also got volte amd vowifi.

Yes, he was referring to the GSM radio. So this will be risky.

Maybe you should not try. You can check if someone did it with G7....

I also have remembered that I cross flashed my G7 from HK to European, to Korean, back and fourth between them and all was fine.

---------- Post added at 06:16 PM ---------- Previous post was at 05:58 PM ----------

Maybe the V line from LG is risky about radios. Or maybe that was on V35. My point is that this is very risky an you should assume responsibility if flashing. Maybe it's better do not try it.
[LG V40 Questions & Answers] AzzKickah:
You seem to contradict yourself, or do I misunderstand? :)

Why check if someone did it if you already did? :)

I will see how it goes with this firmware for a week or two. If it is all fine, I'll leave it like this.

I don't suspect it will brick the phone though if I flash a European firmware.. As long as you can get into Download-mode, there is not much to worry about I think :)
[LG V40 Questions & Answers] Inerent:
:cowboy:

Anyway, the benefits for European are many. Volte, vowifi, less bloatware, faster speed.

Half of me is screaming to DO IT, while the other half is paranoic!
[LG V40 Questions & Answers] AzzKickah:
Faster speed..? Please elaborate.

It shows LTE in the status bar though. But I don't know if that is VoLTE.

Now you're making me doubt if I should try a European firmware.... :eek:

I'm feeling exactly the same right now :laugh:
[LG V40 Questions & Answers] Inerent:
Yes, for my G7 it was faster speeds. Better battery life also.
[LG V40 Questions & Answers] AzzKickah:
What do you think, would this be a good one to try?

V405EBW20a_00_OPEN_EU_DS_0524.kdz

LM-V405EBW...? On my LM-V409N, would that go..?
[LG V40 Questions & Answers] Inerent:
I'll search what country has better laws regarding government spying on people. And that firmware I'll choose. Maybe it's the UK, I know that it has forbidden StingRays. Also Deutschland seems OK.
[LG V40 Questions & Answers] AzzKickah:
But do you think a firmware for the LM-V405EBW would go for the LM-V409N..? Would it work at all..?

Deutschland is a good suggestion, but I can't find a German one in the list for LM-V405EBW.
[LG V40 Questions & Answers] Inerent:
50% Yes.
[LG V40 Questions & Answers] AzzKickah:
I'm scared to try it...

If I do try it and it fails, and then I can't get back into Download-mode, I would be f*cked. Then it's bricked.

Although it seems unlikely to me that it could not go into Download-mode anymore. But since I'm not sure, I'm scared to try.
[LG V40 Questions & Answers] Inerent:
You will be able to go into download mode. I'm 100% sure of that. I'm not sure about radio signal.
[LG V40 Questions & Answers] AzzKickah:
OK, in that case I can safely try. If it doesn't boot, or radio doesn't work, I can just flash the Korean stock one back.
[LG V40 Questions & Answers] Inerent:
Good luck and please let me know when done. :good:
[LG V40 Questions & Answers] AzzKickah:
OK, good news and bad news.

The good news is that flashing went perfectly fine!

It boots.

It makes sound.

Radio is working (shows 4G now instead of LTE)

Everything else seems to be working fine, except..

And here's the bad news:

WiFi doesn't work...? It turns on, but keeps searching for networks. Doesn't show any network.

Even after adding my network manually (SSID, password, etc) it still doesn't see and/or connect to it.

What the hell would be different between WiFi in Asia and in Europe? Also, WiFi worked fine with the Korean firmware (although Tethering/HotSpot didn't...).

This is annoying :( I do need the WiFi.

At least I know now I can try some other firmwares if I want to...
[LG V40 Questions & Answers] Inerent:
Did you crossflash from oreo to pie?

Wi-Fi is the least problem. Glad all works. Try reflashing or factory reset. It should work. Go in setting advanced wifi and select auto select. My V50 has by default to search only for 5ghz wifi. I switched to automatic 2.4/5ghz
[LG V40 Questions & Answers] AzzKickah:
A factory reset indeed did the trick! WiFi works now!

Sir may I say, you are a king.

I will test everything else today and tomorrow but I suspect everything will be fine! If not, I will update here.

Thank you a million times for all your excellent help!! :good: :highfive:
[LG V40 Questions & Answers] Inerent:
I'm glad it helped. I'm also waiting for my V50 DLL to do the exact same thing. :cowboy::angel:

V40 working cross flash - except t mobile

Trust me t mobile doesn't work.
[LG V40 Questions & Answers] AzzKickah:
Hang on... WiFi stopped working suddenly...

I also noticed there are no 2.4/5GHz settings anymore. Also not for setting up a hotspot. In the original firmware I could choose there. Now there is no mentioning of it at all.

Hmmmm.....
[LG V40 Questions & Answers] AzzKickah:
How weird is this.... HotSpot now works. Normal WiFi doesn't.

EXACTLY the other way around from when the original firmware was still on the phone.
[LG V40 Questions & Answers] AzzKickah:
[MENTION=8615083]Inerent[/MENTION] Do you know if there is a way to force the phone to use 2.4GHz? Something similar to editing build.prop maybe?

Try reflash with lg up different European firmware. Also Open one.
[LG V40 Questions & Answers] AzzKickah:
No it's lightning fast!

WiFi doesn't work anymore.

OK I'll try another one tomorrow. Done for today :)

Try reflash with different European firmware. Also Open one.
[LG V40 Questions & Answers] AzzKickah:
[MENTION=8615083]Inerent[/MENTION]

OK, I flashed South-Africa firmware. V405EB20b_00_OPEN_ZA_OP_0711.kdz

Exactly the same problem.

WiFi works during initial setup.

It keeps working until:

- You turn WiFi off (and on again)

- You move out of the coverage area of the WLAN you connected to during initial setup. It doesn't reconnect when you return.

Something after initial setup is being changed somehow. The fact it still keeps working until you turn it off makes it even stranger. You can already see that it can't find any other WiFi network, but the one that you connected to during initial setup is still working.

Any idea what is different between initial setup, and right after? Could we change that back manually to get it to work again?

There are no 2.4/5GHz settings to be found anywhere in the settings.
[LG V40 Questions & Answers] Inerent:
Not a clue.

Put screenshots.
[LG V40 Questions & Answers] Inerent:
Also try not to put your Google account and see if it works enabling, disabling the wifi. Maybe Google restores your wifi settings.

---------- Post added at 11:21 AM ---------- Previous post was at 11:16 AM ----------

You should also check your router and set wifi bands to automatic. Maybe some band is not supported.
[LG V40 Questions & Answers] AzzKickah:
Hereby.

Turning WiFi on takes a long time. About 15-20 seconds.

Then it just keeps searching for networks.

Refresh button in the right-top doesn't work. Doesn't trigger anything and doesn't turn grey when pressed.

The other screenshot shows the WiFi Advanced settings. This is all it shows.

[MENTION=8615083]Inerent[/MENTION] Already tried without restoring Google settings. Doesn't make a difference unfortunately.
[LG V40 Questions & Answers] Inerent:
Strange. Try reseting network settings. System, restart and reset
[LG V40 Questions & Answers] AzzKickah:
Same result :(

I just can't understand why it does work immediately after flashing and turning on the phone. And then not anymore.

I'm going to flash a USA firmware later today. Just to see what happens/what does work and what doesn't.

If WiFi and/or radio are not working on the USA firmware either, I will flash the stock Korean back and live with it.

Frustrating :(

Edit: Do you know what "NAO" means? The other firmwares had "OPEN" in the filename.

V405EBW20a_00_OPEN_EU_DS_0524.kdz

or

V405QA720a_03_NAO_US_OP_0529.kdz
[LG V40 Questions & Answers] AzzKickah:
I flashed the USA firmware on it: same result.

- WiFi takes long to turn on

- WiFi doesn't find any wireless network

- Tethering/HotSpot does work (this baffles me even more)

- 4G/LTE works

I'm going to flash the Korean stock back onto it now.
[LG V40 Questions & Answers] AzzKickah:
Flashed the Korean one just now.

- WiFi works perfectly now

- Tethering doesn't work

- 4G/LTE works

I guess I will just stick with this then.

That second Korean clock on the lockscreen is annoying though.
[LG V40 Questions & Answers] Inerent:
It's important that v40 supports crossflashing.

Also you should try to flash European firmware older model until wifi works. It must work!

Ca you write me what firmware did you flashed?
[LG V40 Questions & Answers] AzzKickah:
Korean stock:

V409NO20f_00_OPEN_KR_OP_0722.kdz

European:

V405EBW20a_00_OPEN_EU_DS_0524.kdz

South Africa:

V405EB20b_00_OPEN_ZA_OP_0711.kdz

USA:

V405QA720a_03_NAO_US_OP_0529.kdz

I suspect there must be some kind of difference in hardware between Asian and other models of the V40.

But I keep wondering why WiFi works for a minute or 2 on initial setup with a non-Korean firmware. I don't understand that one bit.
[LG V40 Questions & Answers] Inerent:
Nope, the problem is that your Korean firmware is newer.

You should try to search for European firmware with 20f. Maybe LG changed something irreversible in that 20f.
[LG V40 Questions & Answers] AzzKickah:
I can't find European 20f on lg-firmwares.com and XDA. If I can't find it there, I have no clue where/how to look for it elsewhere.

V405EB20b_00_OPEN_ZA_OP_0711.kdz	Android 9 Pie	2019-08-15

The South African one is from 3 weeks ago. That's too old?

How do they operate the WiFi in SA then..? :p
[LG V40 Questions & Answers] AzzKickah:

It says 20h but it's USA T-Mobile... That won't work I guess?
[LG V40 Questions & Answers] Inerent:
Do not flash TMobile. It will brick!

Stay on Korean until something newer appears on European
