LG V10 Hard Reset no works and cant unlock bootloader

Hi! First thing, sorry for my bad english
I have a LG V10 H960AR, and works pretty good, come with lollipop but in put mm using lg up and the kdz oficial
The problema is; when i try to unlock the bootloader from the page of lge developer say: My version cant be unlocked", i cant find some tutorial to do this, in Argentina is so expensive to buy it, ergo no much info available
Plus, the hard reset comand dont work, the fissically buttons work perfectly on android, but no do hard reset and no enter to recovery mode
Another plus; platform toos dont recognize it, <waiting device> (in lg g3 and g5 recognice perfectly)
I think the provider (Personal, Argentina) touch the system and "delete" or "freeze" this option..
Any sugestion to unlock the bootloader?
Thanks to read, and again sorry for my bad english- Ill be waiting for answers! :fingers-crossed:
Hi,
I'm sorry to say that your version of the V10 can't be unlocked. Unlocking the bootloader is currently only supported for H960A (European version) but not for phones purchased in France. Also (if I'm not mistaken) the T-Mobile (US) version has an unlocked bootloader. For other versions there is at the moment no possibility to unlock the bootloader.
Regarding the factory reset: have you tried the reset option from the settings (backup&reset/factory data reset)?

Lg H901 T-Mobile with H900 at&t firmware on it ??

Hi guys, i just tried to unlock the bootloader on my father's v10, but can't enter bootloader with adb nor vol up+ power...
then i saw that the firmware is telling me it's a H900 at&t v10 while when i open it and remove the battery it's written it is a H901 ( T-Mobile version), right now it's running android 5.1.1, with no updates available.
How can i put it back to it's original firmware since now the bootloader is locked by at&t ?
oh yeah, and when checking the imei given by dial code *#06#, it is registered as a LG G4...
the one written behind the battery seems right

Rooting available for flipkart sold models??

What region phone do they sell in India, in box it is showing made in Vietnam ,they changed the firmware
Ind I think so..
Is it rooting possible?
If we somehow rooted the device we can tweak the kernel and add fast charge ( it took around 2 hr to charge from 20% I'm really disappointed ),also may be we can fix the infinite focus on the front camera:fingers-crossed:
We living in 2020 even a midrange phone have 27 watt fastcharg support :crying:
No. Rooting not possible. I tried booting to bootloader and couldn't do it.
I have bought mine from Flipkart

Look at the Supported devices page.
Model number for phone named V50s is same as G8X.
I think G8X is called V50s in Korean.
Try putting your IMEI and Device ID, I think they will allow.
There is another thread here with someone who tried it on the European G8X, which has the same model number as the Indian G8X.
A bit of a warning though, I haven't tried this myself. Do it at your own risk.

On that site
First step is to boot into bootloader and get device ID.
As we can't boot into fastboot, we cannot get device id
Yes true. We can't boot into fastboot. Need to request LG to make fastboot available
I too tried and i cant get the id? (no bootloader??)

Yeah bro both phone are same but v50s did not support dualsecreen , specifications are identical to lg g8x
Have a look at:
https://www.gadgetsnow.com/compare-mobile-phones/LG-G8X-ThinQ-vs-LG-V50S-ThinQ
There will be a way to root
I faced the charging issue as well. It ended up being due to the magnetic adapter having fast charging enabled only if its connected in one way, if we flip it, it is very slow to charge. You can even see the 'fast charging' in notification when it is the right way up. Strange and not good, but you just need to ensure the 3 dots on the pogo adapter needs to be showing up. It improved my charging speed quite a bit.
btw, I wanted to caution about force enabling fast charging modes in kernel when they are not enabled by default. I'd done this after rooting my redmi note 3 & soon after it stopped charging altogether and it required motherboard replacement.

unofficial unlocking method for LG G5 h850 ???

Hi there,
since LG ended its bootloader unlocking Service on December 31 - 2021, is there a chance that there will be an unofficial unlocking method in the near future?
Just got a LG G5 h850 which is still looked :-(
Thanks
[UNLOCK][UNOFFICIAL][G4] Unlock ANY* LG G4 device with UsU
About UsU = Unofficial secureboot-off/steadfasterX Unlock *works with any G4 model. Even though the h818 can be unlocked as well the touch display does not work anymore (should be possible to resolve but.. read on). so I decided to remove it...
forum.xda-developers.com
Install /e/OS on a LG G4 (AR,PX,L,P,T) - “h815_usu”
@dave-x, any news? Is this working for h850?
NO it did not work!!!
so I tried
Unlocking the bootloader
Download and Boot FWUL/mAid
Always download the latest iso file
Click to expand...
Click to collapse
Start SALT (folder LG)
Select backup and create a full backup of your device
Check ARB value (must be 0, 1 or 2 but not higher then 2)
Open the Advanced menu
Select Unlock G4 (UsU)
Follow the instructions
but since i have a G5 850
when i select Unlock G4 (UsU)
I get an ERROR message saying: "Your Download mode version is not supported ! Downgrade to LP or MM !
So I´m not sure what that means..
Hi there. I am a user of LG G5 h860. The loader is locked. Please tell, are there any ways to unlock loaders in 2022? Are there alternative ways to download the firmware?
Greetings from Ukraine!
I also have H850 ZAF and would love to run lineageos
It does not look like you will be successful. Unlocking bootloader inofficially is not really easy, as it requires hacking the public key infrastructure used to protect the bootloader.
Check out there: https://forum.xda-developers.com/t/...-for-offline-bootloader-unlock.3603855/page-5
All emails towards LG will be rejected explaining that they do not offer the unlock service anymore. Unbelievably dissapointing, but true. Also I bought the h850, but now I have no use anymore for it. Wasted money.
Just came across this thread, so I just bought a replacemnt h850 from ebay. Very disapointed by LG. :-(
Is there a way to unlock the bootloader today, a friend of mine gave me his phone to unlock it but it isn't so easy I realized. Thanks for all help.
I would move on. I did, even though I've recently bought H850 for family member. Nobody is working on hacking old, cheap, obsolete phones and there is 0% chance LG is changing their minds.
this is very bad, I ordered the phone from eBay from the EU 850 (180eur) version from the seller with a 1 year warranty, new, unopened packaging. In our country there is a service that does unlocking, unlock bootloader, upgrade to LineageOS. I don't know if they will do it for LG G5 if there is a big problem with the bootloader.
I'll have to stay with Android 8 if I get the update. The phone will have if I understand the gsm arena site Android 6 from factory.
Maybe someone smarter than me, this Black Hat Briefings presentation will help find a way to unlock our phones?
I am a noob so I understand a maximum half of it, but maybe it will help someone find a solution.

This looks plausible?
Could just be clickbate but someone went to a lot of trouble to make it if so

it meant downgrade to MarshMallow, which the g5 does have, so this could work

Doesn't "LP" mean "Lollipop" and "MM" mean "Marshmallow"

I tried to downgrade my H850 to MM. But it didn't work. Same error message "Your Download mode version is not supported ! Downgrade to LP or MM !".
I think it only works for G4.

This appears to be a tool for the G4, not the G5. Unless I'm missing something about them adding G5 functionality, my guess would be that's why it doesn't work.

please help with lg g8x

The bootloader has been unlocked and the fingerprint has stopped working and the phone is lg g8x sprint if the phone is re-locked, the fingerprint will return
