Well - my plea to ROM cookers to post their kitchen didn't produce any concrete results, so here's a different question/plea:

What kitchen tools are you using?

I use the HyperCore kitchen downloaded from here (Many thanks Anchillus):

http://xdaforums.com/showthread.php?t=324682

I follow the process described here (Many thanks Laurentius):

http://xdaforums.com/showpost.php?p=1534193&postcount=47

[EDIT: At the PKGTool stage, I do 'Manual', not 'Automatic', and fix any missing files before continuing]

This was all working great for me for quite some time and let me build custom versions of the ROMs posted here. Nothing too fancy, mostly just adding in Ranju's voice notifications, making sure wktask was present, and removing the odd application that I don't use.

Now, however, this process rarely works, if ever.

For Ranju's ROMs, (at least up to 7.4 - I haven't tried with later), the process works, but the Flash Drive disappears -- annoying, because I like to use it for the browser cache.

For PDAViet ROMs, the extract fails with lots of 'overlap' errors.

For mo3ulla's latest ROM, everything *seems* to work, but the ROM locks up when I flash it (and yes, I have fixed the PP=8MB for it).

My 'test' process is to rebuild the vanilla ROM, btw, with NO changes (decode/extract ROM, extract XIP, build ROM, encode ROM, flash). This used to work 99% of the time, but now rarely works with the newer WM 6.1 ROMs.

I greatly admire all the work the various ROM builders do here, but really want to be able to make those little changes (and maybe learn more so I can at some point add in User Customization, etc, to speed up my CAB installs after upgrade!).

Any suggestions for different/better tools, and/or a better recipe for cooking, would be wonderful!

Hello,

I have BIP and I'm happy with it functionality in general.

The problem is that it has not compatibility with the most popular fitness apps. I'm premium user of Endomondo, but i checked also Stavra, Runtastic....

Do you know some app with can work with the smart watch? Or some easy way to get more of it with endomondo?

Thank you in advance.

I did the crossflash of my lg v40 to the US unlocked pie V405UA20a very very simply without unlocking bootloader, root or some other step. Everything works great, my imei was not deleted, nor my serial number. just flash the kdz by installing lgup and ... can i help you to do the crossflash

Everything works perfect but there is no option for Wi-Fi calls? someone knows?
[LG V40 Guides, News, & Discussion] conmonks:
Hello

So could you explain how you did the crossflash with the bootloader not being unlocked. I have LGUP installed and the US unlocked KDZ file. It failed for me.

Which guide did you use or if you care to explain the steps here. Thanks!

EDIT: Figured it out.

New question, are you able to put TWRP on your phone with current methods out there? if so, how?
[LG V40 Guides, News, & Discussion] jimmyStoo:

[LG V40 Guides, News, & Discussion] EddiePR:

[LG V40 Guides, News, & Discussion] EddiePR:
[Guide]

I am not responsible if something goes wrong.

everything works perfect with total comptability, but I can't confirm if fastboot can be accessed after crossflash. Also, there is no option of wifi calling or calling plus, I cannot confirm OTA, because I installed android pie and it is the latest version for US unlocked. ***Maybe if you install the latest android 8 oreo before ,then you can test if ota works***

Downloads:

files: https://drive.google.com/open?id=1b-ZK3pN2ph7JvG6n4sDyXHxGLT53IfvE

firmware: https://lg-firmwares.com/lg-lmv405qa-firmwares/#tab=firmwares

*rename the firmware file to pie.kdz and put in desktop*

install lg usb drivers (be sure your device can adb. enable usb debugging, open command and put adb devices. check notification on the device and hit always. also Switch between all USB connection modes from the mobile so that Windows installs all the drivers

install lg up

Put LGUP_command.dll it into the folder: C:\Program Files (x86)\LG Electronics\LGUP\model\common ( if there is no common folder, create one and put the file there )

now...

put device in download mode

power off device

connect usb cable to pc, but not the phone

Hold and keep phone volume up

Plug your USB Cable to your phone while holding volume up, already in download mode, release volume up button

now go to device manager an check in ports/lge the value number for example com3, save it

Then go back to C:\Program Files (x86)\LG Electronics\LGUP

Hold the shift key and right click on a free space.

Choose to open a command prompt or PowerShell in Windows 10

After oppening it, type cmd and hit enter.

now you need to put this

lgup_cmd.exe com3 “C:\Program Files (x86)\LG Electronics\LGUP\model\common\LGUP_Common.dll” “C:\Users\your desktop username\Desktop\pie.kdz

and hit enter, but need to change the com number value. for example mine was com3. if yours is com2, com5 or another just change the number.

and that is. if you do it right then it will start flashing and you will see the progress on the mobile and the powershell

This does not sim unlock your sprint device. if you could not do the process and switch to the US unlocked rom, I do not understand. If you follow the steps correctly, you end up without problems.

"Everywhere", meaning this one reply of "flashing the US unlocked rom no sim unlocks", which could mean "I am flashing the US unlocked ROM without an existing SIM unlock", or "Flashing the US unlocked ROM does not SIM-unlock".

Did you had to turn or Data Roaming for the Data and LTE to work?
[LG V40 Guides, News, & Discussion] EddiePR:
At least where I live, it connects to 4g lte without activating roaming "in sprint" (using verizon rom)
[LG V40 Guides, News, & Discussion] EddiePR:
you can try and if it doesn't work well, you can install the LG US factory unlocked version. you must install 20a verizon build. I don't know if installing a later version lets you downgrade, since the latest LG US unlocked version is in build 20a
[LG V40 Guides, News, & Discussion] copota:
I flashed V405UA20A, and all works great on my Sprint variant. I used LGUP to do the flash via the upgrade option. However, I'm stuck with the May 2019 security patch.

Can this this firmware get OTA updated to the latest security patch?

When I run the update option in settings, all I get is a message stating I'm on the latest OS.
[LG V40 Guides, News, & Discussion] EddiePR:
It's very weird. I installed that build and looked for a new version and it gave me the option to install a new version. So, ota works in my lg v40
[LG V40 Guides, News, & Discussion] copota:
Did you use LGUP to flash? If so, did you use refurbish, upgrade, or DL?

One other thing, did it OTA upgrade you to the November patch?
[LG V40 Guides, News, & Discussion] EddiePR:
I use lgup. I flashed just using powershell commands. It is my first LG and therefore the first time I flash an LG. I don't know at all those options you mention like refurbish.?
[LG V40 Guides, News, & Discussion] copota:
Thanks for the reply. Can you tell me the date of the security patch you currently have? I'm would like to know if you were able to get the latest patch.
[LG V40 Guides, News, & Discussion] EddiePR:
I am using US version unlocked with the security patch (May 2019) but I tried the verizon rom 20a and the OTA worked for me.
[LG V40 Guides, News, & Discussion] copota:
Thanks again for the reply.

So you're on the same security patch as me (May 2019). I'm just trying to figure out if I'm getting the latest security patched from Sprint.

When I was on stock Oreo 8.1, I was updated to the October 2019 security patch.

Is the May 2019 security patch the latest patch Sprint rolled out for Pie?
[LG V40 Guides, News, & Discussion] EddiePR:
So far Sprint has not released Android Pie, but its latest firmware has the October 2019 security patch.

The pie version with the May security patch is for the LG US unlocked model, not sprint model.
[LG V40 Guides, News, & Discussion] copota:
OK I see, but what I'm trying to find out, is if you can still get security patch updates once you perform a crossflash, which it appears you cannot.

When I got my LG V40, I was on Oreo 8.1, and getting a security patch update once a month. Before I crossflashed my device, I was on the security patch October 2019 update.

After I crossflashed my device, I was no longer capable of getting the latest security patch, even when I flashed back to an Oreo 8.1 KDZ, I was stuck with the security patch that KDZ was built on, and unable to pull the latest security patch update.

So it appears once you crossflash your device, you're stuck with whatever security patch that KDZ was built with.
[LG V40 Guides, News, & Discussion] EddiePR:
I really don't know what happens. I installed the Verizon 20a build and the OTA works.
[LG V40 Guides, News, & Discussion] EddiePR:
What carrier is your LGV40? And what firmware 8.1 did you downgrade? sprint?
[LG V40 Guides, News, & Discussion] copota:
I decided to try the Verizon firmware, and you're right, the OTA security patches download and get applied.

The Verizon firmware appears to work with Sprint data, since I'm still capable of getting Sprint service from my provider (Tello). Though, I don't get any LTE 4G data (get 3G only), which I don't care about since I certainly don't get enough data to enjoy such fast speeds. Personally, I'd rather get the latest Pie security patches than have LTE.

Other than no LTE speeds, are there any cons to using the Verizon firmware on a Sprint phone?
[LG V40 Guides, News, & Discussion] EddiePR:
possibly the verizon firmware is more optimized and the latest verizon version has an October security patch and more. I installed the verizon rom and updated to the latest version and the data works perfectly for me LTE, but, I guess it doesn't grab all the necessary bands to have the best possible data.

But everything works. Data LTE, voice and mms, also RSC. It doesn't grab the signal very well as in the sprint or US unlocked rom, but it works. I re-installed the US unlocked version. I think it's better
[LG V40 Guides, News, & Discussion] samuel6827:
The US unlocked version hasn't gotten any security patched since the May 2019 one therefore there won't be any ota updates till LG releases another security patch
[LG V40 Guides, News, & Discussion] dedncl:
Since Sprint has not released Pie yet, likely they don't have any updates available. Therefore you are stuck with the May revision. The only updates available from Sprint are for Android 8
[LG V40 Guides, News, & Discussion] copota:
I installed the Verizon KDZ on my Sprint variant and updated it to the latest security patch. Though, now I want to go back to either Oreo or the US unlocked firmware, however I'm getting a "0x6004" error when trying to flash back the other firmwares.

Since you were able to flash back to US unlocked after flashing the Verizon, I was wondering if there were any specific steps that need to be done to flashback? Thanks for any advice.
[LG V40 Guides, News, & Discussion] EddiePR:
I really don't know how to help you. I installed the verizon rom and updated to lastes build and then I reinstalled the US unlocked rom again without errors
[LG V40 Guides, News, & Discussion] copota:
Thanks for the reply. I think flashing the Verizon fiirmware via LGUP gave me a firmware with a locked bootloader.

I tried to see what happens by choosing erase chip in LGUP, and I get an error stating the phone is locked, which is probably why I can't flash another firmware. So I'm guessing I would need to get this firmware unlocked to be able to flash another firmware version.

I did'nt have any issues flashing the US unlocked cersions of Oreo and Pie.

I guess I'm stuck with using Verizons firmware. This firmware seems to have some issues on a Sprint variant. For the most part calls work on data, but I sometimes get texting errors.
[LG V40 Guides, News, & Discussion] copota:
I found a fix for my problem. Well, it at least worked for me and my configuration.

If anyone was is in my boat, and has a Sprint LG V40, flashed it with a Verizon Pie KDZ using LGUP found in this tutorial (LGUP for all), then tried to flash to a different firmware and got "0x6004" error. You can try the following to hopefully bypass the error and flash to another firmware.

Visit this thread [LG G7] FIX Error 0x2000 LGUP3

Download the LGUP_Common .rar file linked in step 3

Extract it

Copy the extracted LGUP_Common.dll file into the "common" directory of your LGUP installation folder (same as you followed in the LGUP for all tutorial) replacing the original file.

Run LGUP again, and hopefully you wont get that error again and you'll be able to flash another firmware

A word of warning to Sprint LG V40 owners. DO NOT flash a Verizon KDZ to your phone. If you do, you might be stuck with 3G service, and find service drops easily. Stick to a US unlocked firmware (linked in this thread). I've been using the Android Pie US unlocked firmware, and so far no issues with data connectivity.
[LG V40 Guides, News, & Discussion] jetcold:
Thank you for this!

I just bought an unlocked V40 (formerly Sprint) from eBay, and I loved the phone but immediately ran into problems getting it to run on TMobile (I could not send MMS and the phone kept trying to update on Sprint servers, locking me out every time I turned it on). Making matters worse, my network settings were grayed-out, and there was no option to manually set them.

Your post allowed me to install Android 9 Pie and fix all of that. One thing I will add (because this was not intuitive for me) is that I accessed debug mode by Settings > System > About phone > Software info then tapping Build number 7 times. This was completely hidden and unintuitive for me, and I found it accidentally on a Verizon support forum. But it was the key to setting up ADB and following the rest of your instructions.

Thanks again. This phone is so great now. I was even able to delete Facebook and Instagram after the Pie install.

Can we go back to the Sprint ROM after cross flashing?

I currently have a Sprint unlocked LG V40 LM-V405UA on software version V405U20d; Android version 9 (Android security patch level: March 1, 2020). I am considering cross flashing to US Unlocked ROM. I have read the posts on this forum but I want to confirm a couple of things before I proceed: (1) I am assuming that once I cross flash, I CANNOT go back to the Sprint ROM (I think that I saw this somewhere but cannot find the relevant posts again). (2) Cross flashing will allow me to continue using Sprint. I may move to T-Mobile in future but will continue with Sprint for a while. Thanks.
[LG V40 Guides, News, & Discussion] NGOwner:
If the toggle is greyed out under the service menu, you cannot enable Wi-Fi Calling. It won't work. Maybe you have to call ATT to make sure that Wi-Fi Calling is provisioned on your account. The issue could be with how ATT has you provisioned, rather than with the phone. Once ATT provisions you with WiFi calling in their system, your toggle will automatically enable itself.

I've never done the following, so I don't know what would happen: You might also try the button "trigger carrier provisioning" from within the service menu. That might help also insofar as you will then receive the most recent provisioning info from ATT.

1) Assumption is correct. Sprint doesn't release KDZs.

2) Confirmed. Cross-flashing the US version does not impact your ability to use Sprint. I was on Sprint and crossflashed the minute I got my V40. Worked on Sprint like a charm.

I have the sprint one and cross flashed to the Unlocked version. I am on t mobile so can anybody confirm features such as VoLTE, Wi-Fi calling, and HD voice work? I see the option for Wi-Fi calling in the menu but I do not see VoLTE and HD Voice options. Also can somebody confirm that band 71 works on cross flashed devices?
[LG V40 Guides, News, & Discussion] NGOwner:
I can confirm the following:

1) I see an HDVoice service indicator light up when I call VM or my family members who are also on T-Mobile.

2) I have turned on airplane mode and made another call to voicemail. The call went through. I see Wi-Fi calling service indicator and the HDVoice indicator.

3) I turned off W-Fi and called VM again. Switched over to a web browser, and was able to surf the web while my messages were being played. I believe that is a good indicator of VoLTE.

4) Using the Hidden Service Menu from this post, and several apps out of the Play store, my phone sees T-Mobile bands 2, 4, 12 and 71 towers. And I have successfully been connected to a Band 71 tower.

This is great, thank you!

I bought a used LG V40 on Ebay for $70 (the back was smashed, but still fully functional, so I put a hard case on it). It was sim unlocked on android 8.1, only 15 battery cycles, AT&T model 405UA. Unfortunately where I live AT&T service is not so good. So it worked on Tmobile also, but no band 71, and I had to tolerate all the annoying AT&T stuff.

Following "Eddie PR" 's instructions, I cross flashed the unlocked QA7 android 9 software, and it works beautifully. No more AT&T stuff. I'm now using it on a Tmobile MVNO (Truconnect wireless) and the "Network Cell Info" app shows I'm now on Band 71. I couldn't be happier. This is an awesome phone. Big thanks to Eddie PR.
