bootloader in ICS is locked. Nothing to do about it, for now... later we'll see but, once in JB I don't believe
that someone wants to remain or go back to ICS.

Ok..tnx for clear answer

First welcome to our forum , I hope will find what you need .
Why do you want to know 'how to check' .
It's locked in ICS , unlockable in JB (for devices are EUR-xxx ,, after flash JB see the software info in settings) .
You can check it by :-
Code:
adb reboot-bootloader
Fastboot flash kernel xxx.img
Then you will get an error says :- error partition is locked .
Update your phone to JB and then unlock it , then check it in the hidden menu (3845#*880#) , goto bootloader status (or something like that) then will see it "unlock" (of course after you unlock it) .
About check them in recovery (like HTC devices) , in LG you can check them in download mode , you will see "unlocked bootloader" in the corner of screen .
to get any help we are here and you can ask us as much as you can .

Try roll back to v10h(if that is your latest stock for your phone before official JB update), than use LG Mobile Support Tool (official) , and try to flash your phone with "recovery phone" option in Customer Suport menu in LGMobile Support Tool!
And if you didn't before, try first to use reset and clear cache partition from recovery!
(Make backup of important stuff ..apps, pics..)
Or try to wait a little longer than 30 sec next time..

[Q] Thinking to update to JB. Please help.

Hello everyone, I want to upgrade to JB. Mine is AINDBK. I want unlocked bootloader and CWM. Root too. I actually don't know what to do first. Please tell me-
1. From which link to download V20A unlockable (official direct download link prefered).
2. Root first or bootloader unlocking first.
3. Where to get adb for Win 7 32-bit
4. Exact step of unlocking bootloader (as I never used adb with some script or command and this is my first android phone).
5. Most of all, is AINDBK unlockable?

First Warranty void caution - check yours country LG services warranty agreement wise rooting and unlocking bootloader
1. csmgdl.lgmobile.com/swdata/WDLSW/LGP880/ANEUBK/V20a_00/V20A_00.kdz
2. First bootloader unlock, than root
3. You really should use some of search option on this, but try this http://www.droidgator.com/install-adb-usb-drivers-for-android-devices/, and you need to install latest PC sync or LGMobile support tools for the latest drivers
4. LG email about unlocking : http://forum.xda-developers.com/showthread.php?t=2224020 (to use adb commands you need to run cmd and navigate with cd.. and cd comands where your adb application is, or just navigate with explorer to your extracted folder/sdk/platform-tools folder, hold shift and right mouse click on platform-tools folder, select open command window here )
5. After some forum reading i can only say that the unlocking bootloader is connected with phone because when people flash (above link) euro open software they dont get EURO-XXX (unlock possible) in software information of the phone (not the rule, some people get it to work wirh different region code(codes outside Europe region) http://forum.xda-developers.com/showthread.php?t=2222650) so your is 99% unlockable.

[GUIDE] LGUP for all (no root needed)

Greetings everyone, i go by the name Ainz Ooal Gown. Here i bring you the Official Guide on LGUP to fix a Brick of your device or to simply Cross flash/Upgrade your device from Windows.
First things first if you try this and end up with a brick or your device transforms and tries to take over the world; it's not my fault you messed up not me. So just read all of this thread not just the O.P to, and get out of a bind if you reply with "the thread is too long i wont read it please help" don't expect anything short of "there's a search bar use it"
Second things have changed cross flashing no longer unlocks your Sim capabilities, you must contact your Carrier to have your Sim unlocked. The only other thing you can do is buy the US Unlocked model and root that one.
Third and i can't believe i must add this those of you who have a T-Mobile V40 if you flash a T-Mobile KDZ you'll be fine....if you flash any other KDZ enjoy and expensive Paper weight.
Download These FIles: DLL LGUP UI_Config
No root:
Step 1. Install the provided LGUP.msi (you should now have C:\Program Files (x86)\LG Electronics\LGUP)
Step 2. Install the provided DLL (you should now have C:\Program Files (x86)\LG Electronics\LGUP\model\Common)
Step 3. Extract the LGUP_UI_Config_m250n_[cxz].zip file anywhere on your computer, then copy or move the file to the common folder (the same one the DLL installs too)
Step 4. Enter download mode and flash any KDZ that is compatible with your device with the Refurbish or Upgrade options.
With root:
If you're rooted and BL unlocked, ALWAYS use Partition DL unless you want to go completely unrooted/bootloader relocked.
Download the previous files and LGUPCompatableLAF
Make sure your using fastboot with USB 2.0, it may work with 3.0 but it's better to use 2.0
Step 1. Extract the LGUPCompatibleLAF.rar file anywhere on your computer.
Step 2. Put your phone in fastboot mode. If on Oreo, just power off and hold vol down while plugged in, if on PIE Power off press vol up, while plugged in.
Step 3. In Windows 10 right click the start button and choose either "Command Prompt" or "Command Prompt(Admin)"
Step 4. In the command prompt type cd followed by where you extracted the rar for me it's "cd C:\Users\juanj\Downloads\Flash\LGUPCompatableLAF" ( Windows 7 and older simply when in the extracted folder Hold Shift on your keyboard and right click and choose "open a command prompt here" ).
Step 5. We need to get into the V35 Engineering bootloader, run this command: fastboot.exe set_active b and press enter. (If your on Oreo and have V35 bootloader in Slot_a skip this step.)
Step 6. Reboot, and it should boot straight into the v35 eng if you were already on PIE.
Step 7. Run this command to flash the LGUP Compatible LAF: fastboot.exe flash laf_a laf.img press enter.
Step 8. Now, we need to get back to our A slot, run: fastboot.exe set_active a (again Skip if your already on Oreo with V35Bootloader in Slot_a).
Step 9. Reboot by pressing and holding vol down and power while your device is plugged in (let go of the power button and volume down button and now press and hold vol up before the LG Logo shows up). You should be in download mode and LGUP will work.
Step 10. follow the non root part but use Partition DL, Select all and uncheck abl_a and laf_a to keep the bootloader unlocked in Slot_a then abl_b and laf_b to keep V35 Fastboot access in Slot_b.
Thanks to: @CXZa @maxmotos @Xsavi

yes, bl unlocked also :good:

Thanks for posting this. Can we use this to flash any v405 rom (except tmobile) to any lg v405 v40 phone without 9008 mode?
Can we not flash twrp to recovery for the lg v40 as opposed to using the laf partition? I got a copy of twrp.img from vlad for the v40 which looks like was created by Precious Princewill. I haven't tried it yet. Frankly want to make sure there is a working lg up in case i lose recovery. Also not sure how twrp works with PIE. Does it allow you to flash to both slot a or slot b?

Posts like this sometimes makes me wish I didn't get bl unlocked and root.. So much simpler. With lack of anything really interesting to test and play with like crossflashing on the V30 for example, I can't find the motivation to actually do any of this..

TWRP lets you Flash on the current active Slot, But the current Lineage OS we're working on flashes to the non active Slot for some reason.

Does the current twrp allow backup and restore of the active slot? And how can i tell which is the active slot? Is there a different recovery for each slot? I haven't even looked at what the partition scheme looks like with pie yet.

yes you can have the older TWRP 3.3.0-0 in one slot and the newer TWRP 3.3.1-0 in the other but you can check your active slot in the reboot section of TWRP

You know what, I never actually checked whether mine came with TWRP or not (again lack of stuff to flash). Prolly worth a look see.
GSI huh. Would be great if it'd work properly. My local carrier uses bands that US phones don't enable / use which is why all my LG phones run Korean fw. Those are the only ones that play nice, otherwise it's wifi-only-land fer me.
This is one peculiar thing I've noticed with LG phones so far. Even if the phone hw itself supports every single band under the sun (like me old V30), running certain regional fw disables some of them. Specific to the V30 : Logic dictates that you can go into service mode and enable those and alls good yeah? But no, not with LG. You do that, it then locks you onto those bands never auto-switching anymore. Which sucks when you swap sims or roam on other networks. Like.. dude.. WTH??

Successfully crossflashed at&t 8.1 into Korean 9.0. Thanks!

This has been true of almost every manufacturer now. There are no truly unlocked world phones, at least not in the US. Each firmware is locked to the bands for that carrier with little to no ability to cross flash the radios or enable bands. I have at&t in the USA and they have some sort of deal with most carriers that don't allow their firmware to be posted and their phones are all bootloader locked. You can cross flash them and get the bootloader unlocked, but you will always lose a few bands.
The LG v40 US unlocked firmware appears to have more bands than most (v405qa) which is what i cross flashed to my lg v40. It supports:
LTE Bands: 1/2/3/4/5/7/8/12/13/14/17/20/25/26/28/29/30/38/39/40/41/46/66/71;
WCDMA Bands 1/2/4/5/8;
GSM 850/900/1800/1900 MHz; 800 MHz
CDMA; 1.9 GHz CDMA PCS; Secondary 800 MHz CDMA
https://www.lg.com/us/cell-phones/lg-V405QA7-unlocked-v40
Although after cross flashing this rom, my phone firmware still show v405ua model#. So I'm not sure that it fully has worked or if the v405qa is just a varation of the v405ua rom.

Sorry serial number should always be the same but flashing US Unlocked KDZ which is a V405QA doesn't change the Sprint V405UA to a QA....i forget if it was different on the V30 or not

Which v40 do I have and is my bootloader unlocked?

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
