bootloop, bootloader unlock not possible - LG V20 Questions & Answers

Hi everyone,
my v20 h990ds ( stock without root ) is in bootloop.
When i tried the "DirtySanta" solution, i can do the steps on my device ( bootloop ). So i decide to unlock the bootloader.
I come from the nexus community, so i have searched for a solution by fastboot.
Now then i try to ask to the LG from my "unlock.bin" file, it says that my phone is not unlockable (wtf?).
Searching in to the forum, i read about the "download mode", but when i try to jump in, my phone reboot itself after 4 seconds. Is it normal?
Do you have another solution for my phone?

are you following the directions here > https://forum.xda-developers.com/v20/development/dirtysanta-h990-t3624296
The dirtysanta hack is the unlocked bootloader, it installs the Eng Aboot specifically for devices that cant be unlocked.

Some of those points in the guide, requests that the phone is on.
For example, install Terminal Emulator ecc...
If I try to load the TWRP recovery, with fastboot, the phone says that I need to unlock the bootloader.

[Root any Moto G] with screenshots [Simple Method|Well Explained]

Hi...
This is the tutorial to root any Moto G
To root any Moto G, three basic steps need to be followed... you can either do them manually or use a tool do them for you. It is advised to follow them manually so that if there's some bug in the tool you don't get into any trouble.
CAUTION - You will lose all data and files so better back them up.
For Google Play edition devices, the process is same and only the recovery.img file is different. For GPe CWM Advanced Edition recovery go here https://goo.im/devs/philz_touch/CWM_Advanced_Edition/ and select falcon_gpe and download the latest one.
For AT&T and Verizon models don't do anything written above. Just download the Towelroot app. Its a one click root app and doesn't require a PC. Itis trustworthy but is not guaranteed to work but you must give it a try since it won't do any harm and claims of never bricking a phone. Please reply with the result and your android and kernel version.It will probably not work on phones build after June 3 but you can give it a try. You can download it from the website https://towelroot.com
The three steps are :-
1) UNLOCKING THE BOOTLOADER
2) FLASHING CUSTOM RECOVERY
3) INSTALLING SuperSu.zip FILE THROUGH RECOVERY. (SuperSu is acknowledge as the best app to give superuser and root rights)
UNLOCKING THE BOOT LOADER - The instructions to unlock the boot loader are given in the official Motorola website here https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a . Don't be scared by their warnings.
UPDATE - There currently seems to be an issue with unlocking the bootloader on devices running 4.4.4 though it works for 4.4.2. The issue is with Motorola and is that, the unlock code given by the company is showing an error. They are fixing it and it may take some time though you can give it a try as it won't do any harm. Or you can downgrade the boot loader to 4.4.2 and then unlock it.
As confirmed by the Motorola agent, the problem of unlocking bootloader on 4.4.4 has been fixed
FLASHING CUSTOM RECOVERY :-
To flash a custom recovery, you need these things
1) PC and a USB data cable
2) Android SDK ( developer.android.com/sdk/index.html ) For flashing recovery only SDK is needed but it's your wish if you want to download the ADT bundle. After downloading and unzipping the sdk , open the SDK manager and download only the platform tools for this.. rest is your wish..... and separately download ADB tools and fastboot and extract them minimal-adb-and-fastboot.software.informer.com/1.1/
3) Recovery.img file - You can either use CWM foum.xda-developers.com/showthread.php?t=2563599 or CWM advanced editionforum.xda-developers.com/showthread.php?t=2639583 or TWRP forum.xda-developers.com/showthread.php?t=2561757. EDIT - If your phone had come pre installed with 4.4.4 then use only CWM Advanced Edition. CWM Advanced Edition doesn't make backup on XT1033
4) Motorola drivers https://motorola-global-portal.custhelp.com/app/answers/prod_answer_detail/a_id/97326/p/30,6720,9050
5) Enable USB Debugging mode in your phone by going to Settings-About Phone and then tap the build number until you get the toast 'You are a developer'. Now go to Settings again and you will see a new Developer Options there. Go there and enable USB debugging.
6) Have at least 25% of charge on your phone.
After getting all these things:-
1) Download the recovery.img file to your PC and copy paste it to android SDK/platform tools folder.
2) Boot your phone to fastboot mode by first switching it off and holding the volume down and power button for 3 seconds.
3) When in fastboot mode, connect your phone to pc, go to the platform tools folder, there pres shifft and right mouse click simultaneously and select 'open command prompt window here'.
4) In the command window enter
Code:
fastboot devices
If it shows a number and fastboot then we are good..
5) Then enter
Code:
fastboot flash recovery recovery.img
( where in recovery.img the recovery is the name of your recovery file. Example if the name of recovery file is ABC then enter fastboot flash recovery ABC.img)
5) Press enter and if the command prompt window displays the message okay then the recovery is successfully flashed.
6) Now just boot your phone to recovery mode through fastboot mode by following the on screen instructions and in recovery mode select Reboot System Now to reboot your phone normally.
(see attached images below for screenshots)
INSTALLING SuperSu
To install SuperSu :-
1) Download SuperSu zip file download.chainfire.eu/452/SuperSU/ and transfer it to your phone
2) Reboot to recovery via fastboot.
3) Select install zip and select choose from SD card.
4) Locate the file and install it.
5) Now reboot your phone.

I have a huawei p6 but I'm absolutely not satisfied with that and I bought a moto g for my girlfriend and that is awesome.
The only thing why I haven't bought the g for myself as well is the rooting. That time I didn't find an easy way to root it.
If it is a working method than I will buy the 4g verson with sd card support

I looked into it just now... Currently there's an issue with Motorola with unlocking the bootloader when on 4.4.4...As people say, the unlock code given my Motorola is showing an error... You can still try it.. maybe it's even fixed by now.. Even if it fails there wouldn't be any harm.. Though the unlocking works fine with 4.4.2... You can revert back to 4.4.2, unlock the bootloader and then update to 4.4.4... The thing will be same as you will lose all data and files when unlocking the bootloader and so in reverting to 4.4.2.....(Remember, only unlocking doesn't mean you won't recieve updates, you won't receive updates only if you flash a custom recovery.)
EDIT - I added it to the OP. Thanks for bringing it to attention.

You have Verizon I see. The only you will probably face is unlocking the bootloader.. Oh, wait first let me laugh... lol...OK....At one point of time you couldn't unlock the bootloaders for AT&T and Verizon and then we were blessed by the 'one click root' app by the famous hacker geohot called TowelRoot. This app claims to root all the AT&T and Verizon devices with just a click. You don't even need a PC. Just download the app and in the app chick 'make it rain'. Though this is not guaranteed to work but must give a try as it won't do any harm but there's a chance of bricking the phone but you can easily recover from a soft brick by flashing the stock firmware.
Towelroot - https://towelroot.com/
P.S. - Please reply if you tried this and if it didn't work reply with your android version and kernel version. Well reply with your android version and kernel version anyway.

Sorry I didn't know that. Downgrading the bootloader is a very risky process.
What did you exactly do?
Hey! I have followed all the steps. When i flash de recovery.img, the command prompt says everything is ok, but when i try to reboot into recovery trough the fastboot, it just turns off! It dosn't rebot into recovery! Thanks man!

Please tell which android version your phone came preinstalled with and what recovery you used.
Also when you reboot to recovery, after the blank screen do you see the android logo lying down with a red triangle?

Well it doesnt go wrong like you think so my phone is actually not bricked.
But the command window says that the operation failed so i think something is wrong with this testdrive image from the moto forum.

Yeah they say, if you on 4.4.4 and want to unlock your bootloader you have to flash the motoboot_testdrive.img file wich downgrades the bootloader to i think it was called 40.15 or so after that you have to unlock your bootloader and then flash the motoboot 4.4.4 stock image so that you have the actual one but for me it failed while i try to flash this testdrive image

So basically you want to downgrade the bootloader and then unlock it?
Well if you are on KitKat you can downgrade the bootloader by flashing 4.3 , then unlocking the bootloader and then updating to KitKat
Thanks for the guide. I've already recommended it to someone who was having problems.

Thanks Meuuks13. This worked well.
Also, I've found that you can remove the "unlocked bootloader warning message" shown on boot-up by following the method in the Moto X forum:

Nexus 6p struck in boot loop

Hi,
My Nexus 6p was running the latest OTP update of Android Nougat successfully, Suddenly while using google maps it, restarted and went into a boot loop. All i can see is the unlocked bootloader warning (i had unlocked the bootloader earlier) and then the google logo.
I am able to go into bootloader mode and my system identifies my device as a fastoboot device .
I was able to access my stock recovery but while trying to fix my phone, i tried installing twrp recovery and now whenever I choose the option of recovery mode using my volume keys. it again shows the google logo and nothing happens after that.
I have tried many things, but I am not able to resolve my boot loop. Somebody please help me. Please guide me what should be my approach to this problem
Regards
Ishmeet

FOLLOW THESE INSTRUCTIONS ONLY IF ANYTHING BETTER DOESNT COME UP BECAUSE I DON'T WANT TO FEEL GUILTY IF YOU "FUBAR" YOUR PHONE. I am not an expert in this stuff.. I can only follow instructions and the two videos helped me get out of crappy situation in the past couple weeks.
Follow the two videos below on how to re-install your drivers properly and flash and root Nougat 7.0
First go delete your driver from your PC via Device Manager. Anything that you can associate with N6P or Google.
Then watch this video on how to install new drivers.
This video on how to install Nougat
If you can access fastboot, I would just follow Heisenbergs guide (look In the stickies) and reflash the N stock images manually via fastboot. Also, make sure that you flash the recommended TWRP version that he has linked in his guide otherwise you will have problems with recovery. His guide has saved me multiple times when I messed up my phone.

I think I figured out mine problem. I am not sure what you mean by locked bootloader but in my case I was able to reboot to bootloader by pressing all three buttons (Volume up, Volume down and power button) at the same time.
Once you are there and if your bootloader is already unlocked you can flash your own android. Probably this process is called unbrick your phone. I am surprissed and sad as I am not allowed to post link which can help you. Ask admin.
Any related problem while following process. I can try as I am not very expert.
RIP my English.

And that's why it's a good idea if you do ANY tinkering to your phone that you have an unlocked bootloader. I have screwed my phone up a hundred times over but nothing that a fastboot flash of the stock Google images couldn't overcome.
I'm not sure what situation you're in but I would try to get that bootloader unlocked asap. Just know that when you unlock it, every partition on the phone will be completely wiped to include internal storage (sd card).
I wasn't tinkering that's the thing. I was on the Android beta but I have installed those OTA. I would love to be able to unlock the bootloader but none of the commands will work to unlock it because usb debugging was not enabled or the developer options and I can't boot it to change that.

Can't unlock bootloader, can't finish OS setup

So I upgraded to Nougat on my P9 Lite, unlocked boot loader, used twrp, flashed roms and everything went smooth. Saw a more up-to-date version with no bugs, so I had to downgrade to MM first.
I followed a guide, but I messed up somewhere and ended up having my bootloader locked, and I can't access the OS to enable developer options and oem unlock from settings. The reason why I can't access the OS is that I am stuck in the setup. I am stuck at the part where I have to sign in to my google account. It doesn't show a keyboard, only a microphone, and I can't use that for my password (it won't let me).
Any ideas?
TL;DR messed up during downgrading from Nougat to MM, now TWLR is gone, bootloader is locked and my main issue is that when I get to the google account sign in part during OS setup, there is no keyboard (I can only use dictation) so I can't sign in... So I'm stuck
Also, can I unlock bootloader without access to OS, without being able to navigate to settings, enable developer options and then oem unlock?
1. Stuck in OS setup? Signing in to Google? Hey, it's not obligatory, can't you just skip it?
2. Flashing ROMS locked your bootloader, it's normal, but I'm sure it didn't change the "oem unlock" setting you had surely enabled before. Go to fastboot mode and check Bootloader and FRP status on the bottom of the screen. If FRP is unlocked, you will be able to unlock bootloader again.
3. If you have your TWRP gone (flashed by stock ROM), flash the recovery partition manually - fastboot flash recovery TWRP.img (download from Meticulus Project site).

It is obligatory, I couldn't skip it. I tried to use other methods of signing in, but then it asked me to reset password at the end.
Both Phone and FRP are locked
I think I have missed this, but I can't do it via fastboot because I keep getting "Command not allowed" whenever I try to unlock bootloader or do anything via fast boot.
Also, thank you so much for your time and input. It is much appreciated.
That's weird, I flashed my phone several times with different ROMS (not Nougat) and this setting (oem unlock / FRP unlocked) stayed enabled. Don't know where it sits then and how to change it without getting inside OS. But - what about TWRP? Oh right, you won't be able to flash it without unlocked bootloader... Oh, crap. I would try SRK Tool for Huawei to play with bootloader, it uses fastboot so shouldn't help, but maybe, just maybe? Maybe try flashing whole ROMs through dload folder on SD? Stock 120, 161, Nougat, I would try these. I hope there is some way to unlock FRP, probably it's possible in DC-unlocker (it's a paid software).

Yes, it's very weird. I haven't done the process a lot. But I've flashed a couple of phones I had before, went smooth. Nothing major like this happened before.
I will consider the SRK Tool and I did not know about the DC-Unlocker tool, thank you for telling me about it.
Flashing whole roms through dload folder only works with Nougat for some reason, and I keep getting stuck in the signing in problem because of no keyboard, someone told me that's incomplete software, I'm hoping that's the case, any ideas where can I get it from?
Again thank you Jagiel88 for your time and advice xD
No problem, unfortunately I haven't tried Nougat yet, so search for help on down/upgrade Nougat beta <-> Marshmallow threads .

How to uninstall CWM from Huawei P8, B200, rolled back from MM

I don't have an unlocked bootloader and i flashed the CWM. Now when i try to enter the recovery mode with buttons, nothing happens just turns the phone on normally. I searched for stock recoveries, but didn't found nothing.
I have GRA-L09, B200, Europe Open
Thanks for help!
To get an unlocked bootloader you must go to settings> about phone> build number
and then press build number 7 times
after you did that exit out of about phone then click on the newly-appeared 'developer settings'
there you should find OEM Unlocking and Enable USB Debugging
You'll get it from there.
I have the Dev Ops, but don't have OEM unlock.
But shouldn't you already have an unlocked bootloader to have DevOps?
Don't know. I don't typed any code in to unlock bootloader.
Are you sure you have DevOps?
---------- Post added at 01:58 PM ---------- Previous post was at 01:55 PM ----------
And also try to do it not with buttons, but with your computer
I don't know the script for how to boot into recovery mode but to fastboot, for example, you'd type in >fastboot
when your phone is connected to your PC via USB.
Y'know, just search up 'How to use Recovery Mode' - maybe you just did it wrong

That means you have a locked bootloader, so CWM didn't install successfully.
In other words, you need to unlock the bootloader first in order to successfully install CWM.
So, 1st step - visit the Huawei unlocking code request page, taking your time to fill in the form accurately & submit it.
[Btw, if you don't already have a Huawei ID, you can register for one here: http://www-file.huawei.com/en/my-huawei/register
Then use these login details in the above link to request for the unlock code]
2nd step: Once you receive the unlock code from them, use it to unlock the bootloader by issuing the following command in fastboot mode [the asterisks (*) represent your 16-digit unlock code]:
Code:
fastboot oem unlock ****************
Now you can attempt to install CWM. Where are you getting the CWM img file from?

Ok, so it appears you may have corrupted the recovery partition.
Is the phone otherwise booting into the system & functioning normally?
Also, can you tell us what you are wanting to ultimately achieve by installing CWM?
Just to confirm the bootloader is unlocked, run this command in fastboot mode & let us know the result:
Code:
fastboot oem get-bootinfo
Ok, I just read your post in the other thread about wanting to update B200 to B370.
TheGolem said:
I have b200 but can't install it [B370]. Why?
Early flashed the CWM with flashify succesfully, but don't have unlocked bootloader. And if i try to enter recovery mode, nothing happens. Is it possible, that i cant' install it because of this?

As the guys already said, you do not need to install anything in order to update an official rom.
So, let's leave out CWM, bootloaders, etc for now, & help you update only from B200.
When you try using TopperBG's method to update, what happens?
What is your current FULL firmware version? It will be in this format: GRA-L09CxxxB200 - if everything else is as I've mentioned, I'm interested in the Cxxx part.

Update succeed, it wroks fine. The problem is with the recovery mode.
When i'm trying the button method to enter recover, the phone just normally turns on. When still hold the buttons, black screen. It's with the abd too.

you don't have a unlocked bootloader so you can't have cwm
I said it wrong:
-Android 5 succeed
-If i try to install Android 6

1. You need to install stock recovery for android 5(unlocked bootloader is required).
2. Then you can use the dload method to update.
3. You can flash TWRP after that because no-one uses CWM.

Lg v20 h91820h t-mobile bootloader cannot be unlocked - android 8 oreo

UPDATE:
I successfully unlocked the bootloader, flashed twrp, rooted, updated kernel and roms, tweaking gpu cpu for performance in pubg etc, greenify, flashify, power nap everything.
xposed framework take you in bootloop for this device.
now i am on kernel mk2000, superv20 rom, h91810u, 7 nougat.
if in future anyone feels any problem i am always here.
remember: linus is your friend for this device, and windows 10 suck.
and
sudo $(which fastboot) did miracles for me....
old post:
Hello everyone.
i am new here and i am sorry in advance if i did something wrong. i will come directly to the point.
model number: LG V20 T-MOBILE VERSION, H91820H, NON USA, Currently on oreo android 8.
we are not talking about any kind of roms kernels roots or anything here. just a simple question. " can this model's boot loader be unlocked ? like ever ? or not "
cause i have tried everything, when i say everything i mean everything. followed several posts on internet videos on you tube posts on XDA, tried using multiple PCs, multiple data cables, multiple drivers but for some reason i don't know what, this model's boot loader cannot be unlocked.
THE ERROR:
<WAITING FOR DEVICE> till eternity.
what i have done till now ?
1. lg drivers installed.
2. adb drivers installed with adb fastboot files.
3. updating legacy android adb interface driver, done.
4. went in to boot loader then connected the data cable and updated driver, done.
5. usb debugging oem unlock options activated, done.
6. restarted pc multiple times to update drivers, done.
we all know all it takes is 3 easy commands to unlock bootlaoder
adb reboot bootloader
fastboot oem unlock
fastboot reboot
but in my case i always stuck at 2nd command. waiting for device is shown and nothing happens.
then i ran command, adb devices>> it shows
List of devices attached
adb server is out of date. killing...
* daemon started successfully *
LGH9182bfc6bdc device
next i put the command, fastboot devices and nothing is shown i just go to the next line... c:\adb>
so this is for sure that my device is not connected to the fastboot.
now my only question is, can this device bootloader unlock or not ? so that i stop pushing my limits.
any help will be appreciated.
regards.

To be very precise after following the first step while unlocking the bootloader in the second step when we type fast boot devices it should show some hexadecimal numbers and it should confirm us that our device is in the fastboot mode but in my case whenever I type this command nothing happens that means my device is not recognised to go in the bootloader this is the main problem there is no point in following any of the posts if you cannot complete the very first stage of unlocking your bootloader if you can figure out what exactly is the problem I will be thankful to you because I have followed every step possible I've updated every ADB drivers LG drivers but nothing is helping out as even before starting the procedure of unlocking the bootloader my device is not going in the fast boot also I noticed one thing when I try to go inside the bootloader screen before that in my device manager it is shown as composit device but after that I think it gets disconnected fastboot oem unlock cannot work as it gives a message of waiting for the device after going are using the command ADB reboot bootloader so my problem is the command fastboot oem unlock is pretty useless as it waits for the device and it's stuck there forever please help me out if you can I will be thankful to you regards

Did you downgrade to software version H91810P? Because that should be the first thing you have to do to get everything else to work afterwards.

Thanks for the reply.
Can you please clear me one thing. To downgrade from h91820h to h91810p you need to unlock bootloader if i am not wrong. And in that case we will be back to square 1.
Its not about installing custom rom kernel recovery root or anything. Its only about unlocking the bootloader which i cannot do.
I hope you understand my pain.
I just want to unlock my bootloader thats it.
It used only 3 commands.
1. Adb devices - shows my device.
2. Fastboot devices - no fastboot device found.
This is the problem. When you cannot find any fastboot device even updating driver by going inside the bootloader the entire mission gets failed.
I cant find any solution for this. I dont know for what reason my device cannot be listed in fastboot mode.

NEW UPDATE:
my lg v20 now on software h91810p is actually a T MOBILE version. and when i researched more about it i found out T MOBILE deliberately locks the boot loader of many devices and its unlockable.
possible work around can be if the software version installed on your phone can some how be an international version of your ROM, then only you can unlock the bootloader else none of your commands will work. now i am trying to flash this phone using an international ROM version if i succeed i will update. but according to my knowledge flashing other roms other than t mobile ones will definitely give errors in LGUP.

Do not flash another model's firmware onto the H918! Doing so will permanently brick your phone. The H918 in particular is incompatible with all other variants' software. Also, flashing H918 firmware onto any other model will also brick that phone.

Did you make the Linux USB boot stick
Are you following the guide at all?
PART 3: CREATING A BOOTABLE LINUX USB USING FWUL
DOWNLOAD FWUL_v2.7_x86_64_15GB.zip FROM THE LINK BELOW AND EXTRACT THE IMAGE FILE SOMEWHERE IN YOUR PC.
https://androidfilehost.com/?w=files&flid=214529
DOWNLOAD RUFUS FROM BELOW AND INSTALL
https://rufus.akeo.ie/
INSERT A PEN DRIVE IN YOUR PC AND RUN RUFUS.
INSIDE RUFUS SELECT THE IMAGE FILE AND SELECT START (AFTER SELECTING START SELECT DD MODE IN THE DIALOGUE BOX) TO CREATE A BOOTABLE PEN DRIVE (WARNING: THIS WOULD FORMAT YOUR PEN DRIVE)
NOW YOU SHOULD BOOT YOUR PC FROM THE BOOTABLE USB STICK WHICH YOU HAVE JUST CREATED
THIS WOULD MAKE YOUR PC RUN LINUX OS
