LM-V405 EBW - no fastboot mode - LG V40 Questions & Answers

Hello everyone, wishing you a Merry Christmas & Happy New Year.
I just bought a V40 which I wanted to root (coming from an LG G4 which was very easily rooted).
I just cannot go into fastboot mode no matter how hard I try (to get the device ID and get the unlock file from LG).
Would anyone be able to help please ?

I don't think LG will offer the unlock for your model anyway so the device ID will be pointless for you.
You WILL need Fastboot however. I had a device in a similar spot and needed to follow the "Unlock for All" guide in the guides section of the XDA LG V40 forums to enter EDL mode and get a V35 Engineering Bootloader.

I have a LG-V405TA and would also love to have root but after a lot of research the only option I read was one that requires some soldering. I'm still waiting for my warranty to come in before I try that.
I really wish there was more support for the T-Mobile version of this device.
Good luck with rooting yours.

Trying to go to Fastboot simply reboots the device
Extremely frustrating ...

Hey, I have the same device, two SIMs model and the same problem. I honestly don't know what I'm doing, but I went that far to create an account on LG to give them the device ID and them send me the bootloader. The problem is that after I enter "adb reboot bootloader", it just simply restarts and can't enter "fastboot oem device-id". Tried several combinations with the buttons held, but to no avail.
The phone is brand new, just wanted to get the most out of it. If anyone can work some magic, let me know.

hello if you are not resolve your probleme a i have an answer.
lg v40 dont have fastboot mode in origine you must make the bootloader unlock procedure. i wrote an advice for make your phone ine edl mode
edl mode 9008 v40 very easy
(french) hello I could not start in edl mode with the xda instructions but I found a videos phone on android, connected to the computer by usb. you keep pressing the power button and the volume down button. when the screen goes black...

9008 method is too complicated for me.
Thank you, anyway.

(US) T-Mobile version G7+ may come

https://www.xda-developers.com/motorola-moto-g7-plus-t-mobile/
It has NFC and B71 which G7 doesn't have.
Hopefully bootloader will be unlockable. If so, I may get one and paid in full and have it SIM unlocked, and flash RETAIL ROM
Any update on this? Been holding out on upgrading for this if it's true
If this is right it could be the revvl 3 or 3 plus as product sku is tmo revvl this is from wifi alliance
It's the g7 plus and g7 play https://www.tmonews.com/2019/07/t-mobile-revvlry-official-specs-price/
Can we root it using g7 plus method and unlock bootloader same way I currently have the phone
You can try to get bootloader unlock code it won't hurt nothing but as far as rooting I don't know but should be the same

If you can unlock the bootloader, then rooting will be the easy part as you can usually just flash Magisk (or create a patched boot.img in Magisk Manager and flash the patched boot.img). TWRP may even work too, assuming T-Mo didn't heavily modify the underlying software and kernel.
The only question is gonna be unlocking the bootloader as it's not technically branded a Moto device (although is allegedly has the same codename). Moto may not ship a bootloader code to you, you may need to go thru T-Mobile in some way first.

Knowing they (as in T-Mo) doesn't offer codes, which I figured they didn't, then I'd at least try to paste your unlock code on Moto's site. Worst that'll happen is a message will pop up saying you device doesn't qualify.
t mobile g7 plus bootloader unlock
i can confirm that the bootloader for the t mobile moto g7 plus is locked and could not get a unlock from Motorola website it probably has to be paid for to get a unlock. i am unable to confirm at this time if you can get a unlock i got mine on JOD jump on demand. if someone out there gets one paid for and trys for a bootloader unlock please confirm if you can or not after it is paid for. i think you could but i cant confirm that at this time please any ones feed back would be a big help we should all work to gather on this i hope for a bootloader unlock or a work around if someone figures something out but as fas as i know at this time if you owe on 1 there is no boot loader unlock but just maybe the possibility after it is paid i am not shure if you would have to go though t mobile first to get a unlock thanks and anyone's feed back would be very much appreciated.
Also this is probably the same moto g7 build lake as the one off there website but with t mobile branding and a locked down bootloader so twrp and magisk root should work if you can get a bootloader unlock. if someone does please confirm here if it does work or not thanks and i welcome your feedback from anyone.
REVVLRY+ is indeed G7 plus

Ok I'll try it cause it got it for free and it's paid off. Got it from my job as a gift. So I'll definitely check it out then I'm even more interested. But I kinda doubt it cause the bootloader has the name revvl in it in CPU Z. Bootloader goes by MBM-3.0lake_revvl-43c7c77-190517
Ok so no I tried fastboot oem unlock and nothing happens on the phone anyone else has any idea they want me to try. I'm able to check oem unlock but in fastboot the command oem unlock does nothing on the phone

That's because you got to get a unlock key from Motorola. you will first need to make a account with Motorola https://motorola-global-portal.custhelp.com/app/standalone%2Fbootloader%2Funlock-your-device-b
here is your instructions on how to get a key
Put your device in fastboot mode (power off, then press the power and volume down buttons simultaneously).
On your desktop, open a command prompt or terminal, and go to the directory where you installed the Android ADB (or make sure fastboot is in your $PATH)
At the prompt, type $ fastboot oem get_unlock_data
The returned string will be used to retrieve your unlock key.
Paste together the 5 lines of output into one continuous string without (bootloader) or ‘INFO’ or white spaces. Your string needs to look like this: 0A40040192024205#4C4D355631323030373731363031303332323239#BD008A672BA4746C2CE02328A2AC0C39F951A3E5#1F532800020000000000000000000000 EXAMPLE
Check if your device can be unlocked by pasting this string in the field below, and clicking “Can my device be unlocked?”
If your device is unlockable, a "REQUEST UNLOCK KEY" button will now appear at the bottom of this page.
then get the key put in your email address and you will get UNIQUE_KEY
then in adb put in fastboot oem unlock ((UNIQUE_KEY)) here
then fastboot reboot
If yours is paid for please let me know if it works mine is not paid for.

This is a common method to unlock Motorola smartphone bootloader.
Hopefully you will be lucky to get the code, but you may wait up to 2 weeks after initial release.
I can confirm that Motorola will give you the unlock code.

UNLOCKING AND LOCKING BOOTLOADER WILL WIPE YOUR DEVICE> BACKUP PERSONAL DATA IF YOU WANT TO KEEP IT.
I unlocked the bootloader and flashed the moto G7 plus RETAIL firmware. Everything worked fine except google pay, and verity being disabled.
Installing TWRP would always give me a recovery boot loop, so I stopped trying, instead just booting into TWRP with fastboot.
I cannot get verity enabled, even after flashing stock and locking the bootloader, so that means no Google Pay, no Google Fi, no whatever else requires verity.
Looking at
Code:
fastboot getvar all
Shows a flag that verity is disabled and another flag that warranty is void, even after flashing stock.
The stock firmware I found in a firmware repo, because I failed to do a full backup of my system (I only backed up boot, system, and data).
Would anyone be willing to unlock their bootloader, boot into TWRP, do a full backup, and share it, to see if I can get back to stock with verity enabled? I'd love Google Pay back.

I don't think there's any way to replace the basic 'fastboot oem unlock' command. Which is done with a pc (with fastboot / adb installed) connected to the device (and it's in fastboot mode, which for the v40 requires a pc with qfil to flash the v35 eng abl).
That I think is the roadblock for doing any of the other things, without an unlocked bootloader... then it's full stop. Can't go farther.

I apologize for my duplicate posts. Can you direct me to a thread with detailed instructions for flashing the necessary v35 image. I should have a new laptop coming in a few days.
I am not a total noob as I've used fastboot, adb, and in fact lgup (had a v20 a while back.) it's been a couple of years since I've done any of this as I've been away for a bit.
Thanks again...

Yes, this is the thread to follow to unlock the BL. Most of that is up to date, except maybe the part about getting twrp, but I can help with that when u get to that point.
Some important info you may or may not know, with prior experience: Some carriers make thier kdz available, some don't. So the ones that don't, it means it's imperative you make a backup of any partition first, before changing it (because if u don't, and u mess up, you'll have no way to 'get back').
Also, if you decide to do 'cross-flashing' be sure to backup the specific partitions that contain your imei and s/n, as those can get messed up in the process and without the backups the missing imei may be unable to make a call.
You might also notify a Moderator (see mod list in ea thread) and ask them to del the threads you started in Guides and Roms, because unfortunately, when new people see one person do it, then they do it also, then it just turns into a hella mess.
cheers

Question Motorola G50/Blu G50

Im trying to unlock the bootloader on this phone. with no luck. Ive followed various guides on here.
fastboot devices/adb devices both recognize it. I was able to get the token identifier. which i used on motorola's website for the unlock.
it first told me that it was missing a puid... then it told me it couldnt be unlocked. i used adb reboot-bootloader to get the phone into fastboot mode. 95% of the commands come back failed (remote not implement)
I need help please.
Thats lame. I really want to mod this phone

Hello!
If you want to unlock the bootloader of G50 you need special fastboot from Motorola. Im attaching it in reply. Also you need to have bootloader unlock code.
https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a/ here you can optain your code. You can ask me if you need more. Also i made a guide how to install GSI on moto G50 if you want.
I hope that i helped.

to relock the bootloader, the device has to have a 100% stock rom on it, no modifications at all.
ADB isn't used to relock the BL, it has to be done with fastboot.
To get fastboot on the device you have to use qfil and flash the engineering abl and then go directly to fastboot from qfil.
Look in the guides section and you'll find threads how to get the above done.

there are multiple guides in the guides section re this. They may be for unlocking the bootloader, but in your case you follow it and instead of oem unlock, you type oem lock.

Question Missing OEM Unlock on Cellular VZW S8+ (SM-X808U)

Hey guys,
I've searched the forum but nobody seems to have reported the issue I'm experiencing. The way the posts are worded, unlocking the Tab S8+ is a given. I know the US S22 has no OEM Unlocking officially supported. I've followed all the workarounds to get the option to appear to no avail.
My only theory is that VZW hasn't yet unlocked my S8+ (if it was ever locked to begin with, nevertheless I've owned it less than 60 days). Can anybody confirm if this model can be bootloader unlocked by conventional means either prior or after carrier unlock?
Hi! I'm going to try to find the other user's post who enlightened me in this section, but I might have trouble finding it.
Effectively, no U.S. carrier's version of previous and current Samsung Galaxy Tabs can have the bootloader unlocked - at least that's what I remember them telling me. You have to buy the Wi-Fi only version to be able to unlock the bootloader.
Now - SIM unlock, I know nothing about on the Tabs. Normally no matter what U.S. carrier, that I'm aware of, once you pay off your device (if financed), they'll SIM unlock the device, and although you can relate the two things (SIM and bootloader unlocking), they are completely separate and it's only certain U.S. phones (not Samsung phones or tablets) that getting SIM unlock enables you to also do OEM unlocking, and therefore be able to unlock the bootloader.
Verizon never allows the bootloader to be unlocked on any kind of device, no matter what, and all U.S. Samsung carrier devices - both phones and tablets, are never able to get their bootloader unlocked. I'm not including the rare exception that there's a hack to be able to get root - but most hacks circumvent the locked bootloader - they don't often actually allow the bootloader to be unlocked, and this sort of thing is rarer and rarer anymore.
Edit: I believe this is the post, by @googlephoneFKLenAsh.
Thank you for your thorough explanation. I was expecting the Tab to be the same situation as with the U.S. Galaxy phones, I just wasn't able to find confirmation of that.
I know Verizon is hostile to bootloader unlocking (case in point Pixel). So it was either gonna be my carrier and if not that my region.
Tablets do on rare occasion are exceptions (iirc ATT doesn't carrier lock tablets) so barring an explanation elsewhere I figured I'd post and have that question answered for myself and those concerned.
I don't understand the motivation behind it given that unlocking is already a process that can't be exploited by malware/spyware and carries a myriad of drawbacks/risks.

You're welcome!
I'm not sure I understand what you're saying here, or I'm not sure if you meant to say it differently.
An unlocked (or unlockable) bootloader can definitely be exploited without our awareness.
I agree that I don't understand the motivation - at least in contrast to AT&T and T-Mobile which apparently do allow bootloaders to be unlocked once their phones are paid for and SIM unlocked. I also don't know why or if AT&T and T-Mobile would not allow Samsung tablets to be bootloader-unlocked while allowing other brands.
Overall I think the motivation is the prevention of potentially more problems that users will have and also potentially brick their device and then they wind up with an unhappy customer because the carrier won't consider the device under warranty since it had been fiddled with in a way they're not willing to support (understandably).
Additionally, root malware would potentially be using their mobile network for nefarious purposes.

I have the same s8+ 5G model and I'm unable to get to the unlock option from download mode. I have however managed to turn on the OEM unlock from android. It is very fiddly to get to the OEM unlock option, and it will disappear afterward. The method I used is to quickly go to the developer's options before the tablet fully started after a reboot. It will let you toggle the OEM unlock.
I'm waiting if someone found a way to get the bootloader unlock from download mode. Obviously I have tried all other methods ( e.g> cable + up+down volume )
It's actually not possible to unlock via download mode. Download mode is only used for Odin flashing and the like.
You have to get to the bootloader which I believe is power and vol up WITHOUT using the cable afaik.
If by some catastrophic reason you can't get into the bootloader after that, you can boot the device, enable USB debugging, plug into pc, and run adb reboot bootloader or adb reboot recovery.

Have you been able to get the OEM unlocking switch to reappear after you've already toggled it?
If so, is it still on when it reappears? If it is then there's a high likelihood the device can then be unlocked.

yes, it remains as OEM unlocked. I even tried to see if this could be false positive by flipping OEM unlock back and forth. It has shown the setting is persistence, if you set OEM unlock it will stay unlock. If you set it back to OEM lock. It stays as OEM lock.

You are supposed to boot into bootloader mode and then use the fastboot tool to trigger the unlock.
Either fastboot flashing unlock or fastboot oem unlocking. Something like that.

yes, that is not working ( bootloader mode - doesn't let you choose ). Fastboot doesn't work with samsung, they deliberately change their code, try it yourself.

These are the necessary steps on this tablet to unlock the bootloader - it doesn't involve Fastboot from the Platform Tools. I am aware that on standard Android/AOSP that it does involve Fastboot since for my phones I choose Google Pixel devices.
skrowl said:
Step 1 - Prepare your Tablet (only necessary for first install on unrooted device)​
While Frija is downloading the firmware, prepare your device by doing the following:
Settings > About Tablet > Software Information > Click Build Number 7 times quickly
Developer Options (just below About Tablet on the left column)
Turn on USB Debugging
Turn on OEM unlocking
NOTE: If the OEM Unlocking option doesn't appear, connect the device to the internet, wait a few minutes, then try again
Power tablet completely off (Hold volume down + power button if you haven't changed the Bixby settings)
While holding volume up and volume down, plug the tablet into your PC via USB
Let go of volume keys as soon as the blue-green screen shows up
Press and hold volume up for 5 seconds, the screen will change to a confirmation prompt
Press volume up again to confirm, the tablet will reboot
Unplug your tablet from USB
Go through initial setup. Don't bother copying files or installing anything.
Skip signing in to your Google account and Samsung account. You won't be using them for this step.
Settings > About Tablet > Software Information > Click Build Number 7 times quickly
Developer Options (just below About Tablet on the left column)
Turn on USB Debugging
Reboot the tablet

Ah I wasn't aware that some devices do not require fastboot to finalize unlock and instead immediately unlock when toggling OEM Unlocking.
Is it possible to confirm the unlock by getting the bootloader vars using fastboot however?
Alternately, what's the easiest way to confirm the bootloader is unlocked?

According to this post, you should have your bootloader unlocked now. Could you try following the instructions listed and report back?
Could you also explain in more detail how you can get the OEM unlocking option to appear?
I seem to be having no luck. You do own a US model, correct?

Actually, although the instructions don't make it clear without the context of seeing what's on the screen, steps 5 through 7 are what unlock the bootloader. OEM Unlocking still only (normally) enables unlocking the bootloader:
5. While holding volume up and volume down, plug the tablet into your PC via USB
Let go of volume keys as soon as the blue-green screen shows up
6. Press and hold volume up for 5 seconds, the screen will change to a confirmation prompt
7. Press volume up again to confirm, the tablet will reboot

Also, just as on the Google Pixel and many or all other devices, the easiest way to see that your bootloader is unlocked is the (IMHO) big honking stupid advertisement when you reboot or turn on your device that the bootloader is unlocked and the (paraphrasing) "hey thieves, if you just stole this device, you're in luck because you can hack into someone's account easier since this device's bootloader is unlocked" that stays on the screen seemingly forever.
I know that if they're actually technically savvy they'd be able to find that out anyway, but all this forced pre-boot screen does is punish those who unlock their bootloader. End Rant.
Ah I see what you mean, so It's been stated that US devices either resist BL unlocks e entirely or require alternative solutions.
That being said, has there been reports of UI bugs causing the option to appear on USA models under certain circumstances?

No. I've read every post in this section starting from when I pre-ordered mine (February?), and the only post I've seen about being able to enable OEM Unlocking was from @killerzac.
Too bad that doesn't easily lead to actually being able to unlock, even if the OEM Unlocking aspect was widely reproducible.

yes, that is not working ( bootloader mode - doesn't let you choose ). Fastboot doesn't work with samsung, they deliberately change their code, try it yourself.

Have you found a solution?
I'm in such a weird place. I'm in the UK my first Tab S8 Ultra unlocked originally but after relocking the bootloader I can't get the OEM Unlock to reappear. I needed an unlocked tablet so I bought another one and this one has never had the OEM Unlock option. Waited many sets of 7 days trying different Samsung accounts and Google accounts. I do notice like you that if you get to dev options quickly after boot OEM Unlock is there but it definitely hasn't loaded properly at this point and changing it does nothing. Tablet never gives the bootloader unlock option when you go through the process.
The only thing ive noticed is on both devices the KG Status is Active (Viewed in Download Mode). My S22 which has the OEM Unlock option shows it as inactive. Samsung have told me that I can send the tablet to them and they will look at it but I can't be without it at the moment. Don't know if both my tablets are wrongly reporting that they are in finance and MDM is locking it potentially following my Samsung account to the new tablet I bought.
Really annoyed with Samsung now spent hours on web chats with them where they keep making you reset the tablet and won't escalte it.
Even more annoying they won't look at my first tablet because it did unlock initially so the warrenty is void now that it won't unlock they have said they will replace the mainboard for £800.
@Jono0907 That really sucks! I'm sorry to hear about all the trouble. I "swear" - customer service these days. Someday, companies will just stop even having the (mostly) nearly useless customer service that they do now, and they just won't have any at all.

Hi Jono,
I haven't look at it since and I'm pretty sure your finding is very much same as mine, Quote "Table never gives the bootloader unlock option". I gave my s8+ to my 5 years old son as his toy now. Piece of garbage without ROOTing for me. I'm reverting back to using my tabS6. You might hapend to see me on the northen line with my TabS6, very rare scene.
