Which v40 do I have and is my bootloader unlocked? - LG V40 Questions & Answers

Hi, I recently purchased a used v40 online and I'm trying to figure a couple of things out:
1) Which exact model / variant it is
2) Whether or not the bootloader is unlocked.
I'd like to upgrade to the latest OS update for it, but the Android update check suggests it is running the latest version. I'd also like to install TWRP and root with Magisk.
In terms of OS version, here is what I know:
1) There is no external carrier branding on the device (ie. no Verizon or Sprint logos)
2) It is running Android 8.10 with December 2018 security patches.
3) It is running build number OPM.171019.026
4) It is running Software version V405UA11d
5) Even after a factory reset there are no carrier apps, only Google apps / services.
Anything else I should check to know which exact model it is so I know which version of the latest ROM I should flash?
In terms of boot loader unlocking, this is what I know:
1) In developer options I am able to enable both OEM Unlock as well as USB Debugging.
2) I can connect to the phone in adb mode
3) I can boot to recovery and download mode, but can not get it to boot into bootloader mode (if I run adb reboot bootloader (or select reboot to bootloader from recovery) it just boots normally back into Android.

Yours is the UA as i see it says in the softwre but yet it might be an AT&T because you cant recieve updates unless using their sim card meaning that if you font then youll get messeges that its updated. You can forget about bout pie if you play games and use hevy social media on you phone because pie is slow on the v40. In terms of root and bootloader unlock try this, although i havnt tried it. https://forum.xda-developers.com/lg-v40/development/unlock-lg-v40-via-9008-root-t-mobile-t4042207

Cannot boot - Bootloader is locked - Cannot flash

Per title, Nexus 6 will not get past the white "Google". I can get into recovery fine. But the bootloader is locked, so I cannot properly flash stuff. Attempting to unlock the bootloader, I'm told I need to enable the option in the settings menu that I cannot access.
Looks like I'm not the only one I have the same issue and nothing works

is this happened after trying to install update with adb sideload?
I got my nexus 6 today and tried to sideload the ota zip file, but I had no luck and now my nexus can not boot. I had enabled the option for bootloader unlock but my big mistake was that i tried to factory reset the device from recovery and now the bootloader can't be unlocked.
supposed to be experience with nexus devices, but with the bootloader locked I don't know what to do.
any ideas guys?

Yeah I think that's what I may have done too. I was just trying to go back to 100% stock (ignoring 5.1 even).
And of course NOW the 5.1 image is up on Google's page.
Have the same situation: flash 5.1 OTA and then wiped system
Now I can't unlock bootloader (as system just cant boot) and can't flash stock image (as system.img can't be flashed with locked bootloader)
I do not want to believe this is a brick, but it is very likely it
Sadly I've just done the same thing. ADB updated from 5.0.1 to 5.1, and the system.img didn't copy correctly. Phone wont boot past the Google splash screen, and I can't flash a factory image to recover the phone, because in order to unlock the bootloader I have to enable the option in developer settings, which I can't get to because the phone wont boot!
I understand the purpose of having an extra layer of security to prevent malicious types from trying to flash factory images onto stolen devices, but surely any system that allows a user to brick a device simply by leaving a setting unchecked (in a hidden menu, no less!) is asking for trouble? Particularly on a developer orientated device like a Nexus.
It seems crazy that a developer can ADB the official Google Android OTA zip, using the official Google Android SDK, onto the official Google Android flagship device, and the simple corruption of one of the sent files can cause the device to become totally unusable. Surely, say, providing an option in the developer option settings to PIN protect the bootloader, rather than just preventing it from being unlocked all together, would be a more sensible choice?
For what it's worth, I explained my situation to Google, and they are replacing the phone under warranty. This is probably your best (or only) option at this stage.
Good luck, and please let me know if you do manage to find a work-around/ solution to your woes!

can we unlock the bootloader

It ws esy unlocking the bl in g5s+ , what about the z3 play, wife surprised me with this phone, im liking it already, but would like to unlock the bl and eve tually gain root/custom recovery ?
Anyone?
Depends on the model you have specifically, certain ones cant be unlocked such as amazon version. But the steps are the same as all other android phone bootloader unlocks, Steps can be found on motorola website:
https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a
The basics consist of:
enable developer mode
enable "OEM Unlock" in developer settings
fastboot into phones bootloader and run OEM unlock commands
copy unlock code from phone that you get using oem unlocking commands into motorola website
receive email from motorola with unlock "password"
enter password into adb terminal
phone will be wiped and bootloader unlocked
Thats what i thought, i went there just to see , looks the same as for my G5S+ , ill likely do this. Is there guide somewhere on instally magisk as im outdated ( an old chainfire guy) just need some hints , doesnt look like twrp works , what about clockwork mod? Thats fine as well, , any good roms? Think 9 is comming?
Magisk root is straight forward. You can either get a working boot.img for your device from a firmware package and patch/flash it yourself. Or boot NOT flash the twrp images from the twrp website and install the magisk zip that way. The twrp for this device hasn't been compiled for flashing. It boots but flashing it to your device will boot loop it. No custom ROMs that I know of but I'm just using stock with magisk and it's fine once you have root to delete the bloat ware apps and install tweaks from magisk.

Plans, am I doing anything wrong?

Hello all,
I live in the U.S and am planning to get the international version of the phone (Mi 9T Pro) from this link: https://www.amazon.com/Xiaomi-Display-Snapdragon-Factory-Unlocked/dp/B07X55XTBP and run Ting (Operates on T-Mobile, so primarily band #4). However, I haven't rooted a phone since a Galaxy S3 in 2015 and am currently running a Moto G5 Plus: So this is a massive change and I have a bunch of questions.
To begin with, my goals:
1. I want to root the phone, primarily, but still maintain fingerprint sensor to unlock phone
2. Using that, I want to install a Google Camera 7 port (with astrophotography).
3. I'd like to keep MIUI, ideally with OTA updates (not sure if this is possible with a rooted phone?).
4. If there's any way to make cell service better (unlock bands that are locked, like band 12?), I'd like to do that as well.
5. Google Photos automatic backup is also a necessity.
Are there any other improvements that you all would recommend? I've taken a look the threads here and will be doing the following:
- Create a Xiaomi account in order to unlock the phone bootloader
- Boot into bootloader (is there a setting that I need to go to before the next step?)
- Using TWRP .img from here https://forum.xda-developers.com/k20-pro/development/recovery-unofficial-twrp-xiaomi-redmi-t3944363, run 'fastboot flash recovery twrp.img'
Now what? The phone is.... rooted? How does one install xpozed and magisk?
As for google camera: https://forum.xda-developers.com/k20-pro/themes/collection-modded-google-camera-ports-t3991817 Android 10, link #3. (What's xml support?)
Thank you all for your help, a lot has changed since I last worked with this stuff
Unlocking bootloader and rooting does not break fingerprint. Unlocking extra bands is IMPOSSIBLE.
Regarding how to root, after 1 week wait of unlocking bootloader, you will have to flash push TWRP and then flash a magisk file. There's a thread for it.

No, you cannot flash TWRP and from TWRP the oeminfo and no-check recovery, network patch... without the unlocked Bootloader

First, keep your code (on several places, even printed on the paper), it is good for relocking/unlocking (you never know, some actions may lock the Bootloader back) for the lifetime of your phone.
You don't want to go buying the same thing again
Assuming you know how to enable OEM Unlock in Developer's menu and you are a little familiar with Fastboot, it is simple to unlock the Bootloader
Code:
fastboot oem unlock <your code>
If not familiar, and if not clear as below, search on Google how to:
- enable Developer menu by clicking 7 times to the build number in Settings/About
- enable OEM unlock in Developer menu
- install "Minimal ADB and Fastboot" to Windoze (smallest, self containing package with everything for ADB and Fastboot)
- reboot to Fastboot: keep pressing Vol-, then Pow button
Unlocking Bootloader triggers hard-reset, wiping also Internal memory. Backup as much as you can - use Google account, HiSuite, WA own chat backup, copy DCIM to PC, Contacts can be exported to vcard file, etc
Rebranding to AL10c00, upgrading to b540 Oreo, applying the neccesary Network patch to make SiM card(s) working - all is in deep details explained in the OP posts:
https://forum.xda-developers.com/p9/development/rebrand-update-tool-hwota7-p9-eva-t3820849
Read two times before you start, and keep the instructions opened on the PC while doing - wrong moves can cause (soft) bricks

Thank you, Brother, I have done all procedure and my device is now at Oreo, Build EVA-AL10 8.0.0.540(C00).
After doing all the required steps I have flashed Huawei's Official Recovery and enabled OTA, after that I have received an OTA update of 3 MB, Should I install the update or not?

It is safe, just some Patch02 (never found exactly what for).
If you don't mind, you can skip (you can disable OTA - see in OP)
If you go for, you must first flash back the stock Recovery, hence not having TWRP. Not sure anymore, maybe also stock Ramdisk, hence not Magisk
Patch02 will not affect Network Patch or Face Unlock (cool add-on, see OP)
If you didn't apply Network patch yet, etc - then accept Patch02 and continue with OP instructions.
If you already rooted by Magisk, then don't bother with Patch02, too much trouble preparing clean sheet for OTA and rooting again

I have already applied Network Patch, See my both SIM is working.
Right now I don’t need Root so I'm skipping Magisk.
I just want to disappear the update available Notification, if the update is Safe I'll go for it.

I'm from Bangladesh, some Operator in our country introduced VoLTE.
It seems there is an option called VoLTE after upgrade to Oreo. Is it really works?

Nope, VoLTE does not work.
Everything else, like location sharing and Ok Google are fixed with Network patch, but not VoLTE.
The guy who did the whole majestic work went tired (although he believed he was close to fix VoLTE) and gave up. Later he upgraded to newer Huawei devices with Pie, etc, and eventually moved away from XDA

Brother, How to remove the warning when Phone boots "Your device has been unlocked and can't be trusted"??

It's not possible to remove the warning on booting "Your device has been unlocked and can't be trusted" (IMO, it must have been commented somewhere in the OP) - that's price for the unlocked Bootloader.
But you must not relock Bootloader - it would trigger Hard reset, removing Network patch (even worse, it could also cause soft brick if TWRP or Magisk are installed)
15 credits for unlock in fastboot mode (not pay over sms)

Did I soft brick or hard brick my P4XL?

Eager to try out Android 11, I sideloaded the ota zip of the latest Developer preview on my Pixel 4 XL. I have the Verizon version, so my bootloader is locked and I was unable to get it to unlock. So, I figured the ADB sideload method would be perfect.
Everything went smoothly until after the OTA was installed:
I just get a screen that says "Can't find a valid operating system. Device will not start." -- this screen appears for recovery and rescue mode.
The only thing I do have access to is Fastboot. Device appears when I type in "Fastboot devices", but I'm guessing that it doesn't matter since my bootloader is locked and I can't flash anything?
Google support was no help and just send me the address of a repair shop.
Does anyone know if I'm totally F'd in this situation?
Thanks
Nevermind I'll keep looking
Can you change slots? fastboot --set-active=a
It tells you what slot you are on in the bootloader screen. It won't hurt anything. You can always change it back. It's the only thing I know to try.
You can get a stock image and flash it from the stock recovery; dont recall how that procedure is done but there is a guide floating around here as it comes up every once in a while. Usually a Verizon owner...
Are you able to unlock the bootloader (activated before sideload)? So flash unlock and then the factory Image. If you can't unlock your bootloader you are stuck and best option is to open a warranty case by Google...
Try this - https://pixelrepair.withgoogle.com/
You may need to use a VPN if it says not supported in country. Never used it before but worth exploring.
