Need help Unlocking the FRP lock on G8 ThinQ LM-G820UM - LG G8 Questions & Answers

Hello everyone I'm new to this forum but I'm at the end of my ropes. I bought a phone off of eBay it's a great phone but it's FRP locked!! And the last owner does not have the information to unlock it. I tried every YouTube video I possibly get my hands on but no luck.
I even paid somebody in Spain to unlock it through a company but they didn't have the tools to unlock it either. I'm really hoping that someone here in this forum has bypassed the FRP lock on this specific phone.
Here is my specific phone: LG G8 ThinQ LM-G820UM. Someone also told me that I could re flash the ROM, it is a Verizon prepaid phone.
I'll be willing to try that if someone can give me a step by step instructions how to do it and what tool I will need.
Thank you for any help that you can possibly give me.
Thanks

G4 how to root it? (dont understand whats with bootloader and so)

Hello there, i got an LG G4 h815 few days ago, when ever i get new device first thing i do is root it, and it was always very easy for me.
with this g4 i got problems, try to go to LG website and unlock bootloader, it say i cant cause my device is h815 taiwan, so i read more in google and understand official unlock is only for the euro devices.
so i google more try to understand how can i unlock it unofficially, and found nothing, as well as try to google for a way to root it with out unlock bootloader, and also coulnt find.
im sure im missing something, cause i dont think its possible that there is no root for an old device, any help on how to root my phone?
thanks a head.
Lots of people here have H815 TWN...please can some one make a specific thread for rooting or installing xposed on Taiwanese H815 without the risking of bricking or bootlooping the device...meaning successful rooting ...

unfortunatelly you cant unlocked till today.. maybe later if someone can do it... but you can add root to locked bootloader... i have not tried this method.. i tried similar to h811 tmobile.. but its the same procedure.. mine is unlockacle but i dont want to with the bootloop issue... unlocking bootloader voids warranty. and root too but you can always try the kdz that disables the big cores and undo the root..
http://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586
thank you, i found the root for locked bootloader, i done it, but its only for 5.1 android, and i still cant flash roms, only one rom witch they make for locked bootloader, so after all the process went back to unroot 6.0 androis >:
hope some1 will break this bootlock .

Malware on cheap eBay LG G4

Hey guys,
i bought a new LG G4 from eBay for around 130€, normally is costs like 230€... But there where many cheap offers too.
Originally it was a T-Mobile-Version, but on eBay its selled as unlocked...
I think there is malware installed, because some weird popups appear, the battery drains, apps install without me doing sth.
So i tried to root it and install the original firmware, but the first step in every tutorial is to enable the OEM-Unlock, but when i click it and then click apply, nothing happens?!
The Softwareversion (h81121y) is weird too... I cant find no information about this in the internet.
Any idea what to do?
Thank you...
OEM Unlock is for unlocking the Bootloader only, you don´t need that for flashing a Rom
Enable USB-Debuging in the developer settings and flash with LGUP a H811 Firmware of your Choice. All find this here on XDA.

About all versions of LG G7 unlock the bootloader and ROOT discussion

I am from China, I don't know English, this article is translated by Google, but I hope you can read it.
In our place, there are technologies for all models of G7 to unlock bootloader and ROOT (T-MOBILE version of the phone needs to be replaced with a cup to become a general version to unlock the bootloader, because this version of the phone cpu is encrypted), but, frustrating Yes, this technology is only in the hands of a few people, they do not intend to share, and they use this technology to gain benefits.
They provide remote unlocking of the bootloader and ROOT services, but need to pay 150 yuan, which is expensive for me and is meaningless.
I bought a G7 from a second-hand merchant who replaced the RAM with 4G and changed it to 6G. He said that the machine replaced the T-MOBILE version of the CPU, but the IMEI code displayed on the machine is the Korean blue version, and my G7 is Red, I don't know if G7 has changed the IMEI code. If so, please let me know, thank you
My mobile phone, the merchant has helped me unlock the bootloader and ROOT. And, since someone on XDA has shared the cracked version of LGUP, I can use it to brush in any version of my G7. I brushed Korea, T-MOBILE, and KDZ in Europe, and in Europe and Korea. The version of the system ROOT, because now only the European version and the Korean version of ROOT BOOT, I brushed into the boot through FASTBOOT, but, very strangely, I brushed the three versions of KDZ, only T-MOBILE version KDZ can enter FASTBOOT via ADB commands or keystrokes (maybe this phone is T-MOBILE version), other versions will only restart. Therefore, I have to first brush into the T-MOBILE version of KDZ into FASTBOOT to brush into the version of ROOT BOOT I want, then brush into the corresponding version of KDZ, and then install magisk, you get ROOT. However, I am not satisfied with the current system version, I want a newer version, and make it ROOT BOOT, I brushed KDZ many times, when I entered FASTBOOT again into BOOT, I found that I can't brush BOOT again. And FASTBOOT prompts to open the OEM to unlock
So, I entered the system, clicked on the developer option, found that the OEM unlock option has become gray, and can not be opened, so my phone can not be brushed into BOOT, I am looking for ways online, unfortunately, I have not I found a way to succeed. Later, I saw the latest V30 unlocking Bootloader post. It seems that after unlocking the bootloader, the OEM unlock will turn gray. It will take a few days to open again. However, I didn’t see it. Before the V30 post, I have already entered my G7 into FASTBOOT and re-locked the bootloader via the adb command.
Now I can open the OEM to unlock it, but it is useless. Because the bootloader is locked, I still can't brush it into the BOOT through FASTBOOT. Because the bootloader has been locked back by me, I did this, I thought my G7. Is the T-MOBILE version of the replacement CPU machine, in our case, it is said that after the T-MOVILE version of the machine to replace the CPU, T-MOBILE G7 can unlock the bootloader, and will not lock
Now, I am trying to find a way to unlock the bootloader, but no, yes, no, I hope to get some clues to unlock the bootloader by contacting those who have remotely unlocked the bootloader and ROOT by paying. However, no one wants to do this, they I even told me to go away, maybe because they have already paid to unlock it, and telling me will damage their interests. Finally, I learned about the process of remotely unlocking the bootloader by one person. Those who master the technology to unlock the bootloader do not want to expose it. They help the remote unlocking of the bootloader and block the operation process, just through the chat software. Release the command to let you connect to the computer or switch the phone into LG's brush mode, etc. I want to get some information through the screen of the phone. Unfortunately, that person doesn't remember, I only asked some strange news, that person's The mobile phone is a Korean mobile phone that does not unlock the bootloader. The mobile phone version is Android 9.0 South Korea's 20c. The remote flashing machine does not know how to enter the Korean version of FASTBOOT on this mobile phone that does not unlock the bootloader and ROOT. As far as I know, the Korean version The FASTBOOT of the mobile phone is hidden and cannot be opened by the command. This thing has been said on XDA... This thing makes me wonder, I thought they used the tool to brush into the European version of the system and then enter FASTBOOT to unlock. (Unfortunately, my G7 can only enter fastboot by brushing into the T-MOBILE version, the European version cannot pass the adb Or in the form of platinum enter). Some time ago, someone discussed on xda how to unlock the bootloader by brushing into the European version of the system. Since the cracking tool did not come out at the time, they hoped to use the octopus box to brush into the European version of the system and then unlock it (how to unlock without explanation), now crack The tool came out, it can make our G7 brush into any version of the system, but the discussion is gone...
If you have any ideas, please let me know and send it to this mailbox at [email protected]. I am not very good at using xda, and I need vpn on xda. I also need to pay for using VPN. I am poor, this is for me. It’s too much trouble...
*I have a few questions that need your help, 1 how to change the IMEI of G7, I want to try to get a network upgrade by changing imei to the corresponding system version.
2 How to unlock KDZ of G7, I need to unlock KDZ of G7 to extract BOOT.IMG into ROOT BOOT, I tried new methods and some old methods that I can find in my country to unlock KDZ of G7. failed
If you have a method, please let me know (hopefully have a tutorial), I hope to get your reply, thank you...
thanks for your sharing。
Intresting things they do in China. This is why I never trust buying a chinese brand. I bought in 2015 3 xiaomi mi3 mediatek clones from official shenzhen mi store. Never trust chinese brands again. That applyes for software also.
What version of kdz do you want? I have most versions from European model and 2 versions form Korean pie.
Update instructions, I used my friend's Korean version G7 to brush into T-MOBILE version KDZ tiles, can not boot, now only into 9008 mode, now confirmed that the replacement of CPU G7 seems to have become a strange machine, it seems that it can be cracked version of LGUP into any version of KDZ will not tiles, but other machines can not, such as my friend's Korean version machine brush into T-MOBILE machine. It will change into bricks, but one thing is certain that KDZ of Korean and European machines can be brushed into each other, because the publisher of LGUP cracked version is using this tool to make European G7 brush into Korean G7 9.0 system, but it is possible to brush KDZ randomly into Korean G7 system. I do not recommend that you do so. I do not think you have the hope that your machine will become a brick. If it has happened, I'm sorry, I can only say that, but I hope you can share it and let those who have not happened avoid it. I need more communication and look forward to your reply.
It has entered 9008 mode. Can I change it to European IMEI and ID, then get the unlock file, brush it into European system, and turn it into a European machine, then unlock BL. In theory, the hardware of G7 is the same... I hope someone can share the IMEI and device ID of the European version G7 to me. It's better to have unlock.bin file. I want to test it. My mailbox is [email protected].

That will be verry nice. Is it ok if I give you one from one g7em un retail mode but that has sim enabled?
Any update on this? Would be an interesting method, i would absolutely do this if it works

No you can't. Starting with SD845 - IMEI and ID stays in CHIP and regenerates on every boot.
So, the only way to achieve it is to contact this taobao seller and he will resolder EU chip, flash EM firmware and unlock it and then re-solder back your chip and you will have EM firmware but IMEI and SN will be 0.
N.B.:Regarding G7 it is build in 3 factories and has 4 different Hardware revisions so stop thinking HW is identical and simply cross-flashing will do the trick
So no way to sim unlock the lg g7 tmobile?
lmg710em unsupported country
Greetings everyone;
Since my lmg710em is registered in an "unsupported country"; I cannot unlock my bootloader with official way. I've looked for hours to find an unofficial way but there is nothing... I have tried to flash France's kdz, but nothing changes. Does someone have the european version's unlock.bin file? This is my only hope for now.
It's really bad to be forbidden to use the device, which you paid for, as you like.
I really need help guys,
thank you all,
cheers...

Wow, makes sense man, thanks! But there is only one problem... I dont know how to do it

Is anyone having trouble unlocking the bootloader on the european version? (LMG710EM)

hi, so I was trying to unlock the bootloader before attempting to use an AOSP pie rom using this guide on the official LG site http://developer.lge.com/resource/mobile/RetrieveBootloader.dev
Anyway when I come to step 9, I type "adb reboot bootloader" and the phone reboots in fastboot mode. Then when I type "fastboot oem device-id" the phone freezes and I have to press the power button to restart it, meanwhile in the powershell command page it says
Code:
C:\Users\chahi\AppData\Local\Android\Sdk\platform-tools>fastboot oem device-id
FAILED (Write to device failed (No such file or directory))
fastboot: error: Command failed
I checked my drivers and everything seems to work perfectly fine. I am at my fifth attempt and I'm beginning to feel pretty desperate. If anyone encountered the same problem or could help me solve this I will be very thankful !
Thanks in advance.
NB : I'm on windows 10 and my phone is running the korean pie rom.

I cannot 100% say what the cause is with certainty (I have the Sprint version and I absolutely hate this piece of trash) but others have reported similar issues from actually having a different variant that was cross-flashed to the EM model and sold as EM when it's really a Sprint version (for example). What happens when you enter your IMEI number in LG site, does it return the EM variant or something else? That's where I would start (unless you have already done this and confirmed it's EM). Non EM versions lack the full ADB support so we can't unlock the bootloader. This is the same point I lockup as well but mine was not intended to be unlocked.

Thank you for the quick response !
Yes I actually typed my IMEI in the LG site and it gave me a gray OK so I guess I truly have the EM version ? (knowing that only the EM is supported idk) Are there other methods to make sure I have the EM version for sure ? Also worth noting that I bought the phone new from North Africa so it must be the european version and not a carrier one.
Thank you !

Not that I'm aware of but if the LGdev site let you get the unlock code then I will assume it's real as they do validate it. Normally I would suggest to reach out to LG but that's a waste, they won't help. In fact they shutdown the dev recently because of unlock requests so they don't care about us so that won't help you. I'll do some research and see if there's any official way to help but hopefully others will chime in with the answers.

Good luck with LG, they most likely will do nothing to assist you. That's my biggest gripe with LG, they suck with customer care nor give 2 craps about us, the customers. My LGG7 sucks so bad, it's barely usable but they will not do anything to help me nor Sprint so I'm leaving both once my horrible lease is up. All I can say is to sign the bootloader petition and leave LG, it's the only way they will ever change and even then, they probably won't. They will soon be out of business just like Blackberry's downfall and for the same reasons. They don't listen to the customers and change, nor did RIM with activesync, now RIM is a mere fraction of what they used to be, LG mobile is next. I hear so many complaints about LG devices, not just LG mobile but the entire company. All the same type of complaints across all LG products, no customer support when the device stops working and they pass the buck every time, and locked bootloaders (for LG mobile).
There is no unofficial unlock yet, that's why I'm so unhappy with the piece of junk! If I could unlock and install my own flavor of AOSP then it would be an entirely different story and I would fix my own issues and have an awesome device. Instead the jackalope in charge of LG decided to keep the bootloaders locked with no support to unlock (except for EM) but even that barely works (your issue).
I don't know what else to say except LG SUCKS, LG is terrible. I so wish I hadn't let the Sprint rep bully me into this horrific device. I should have stood my ground and not accepted the deal which came with this expensive paperweight (LGG7).

SIM unlocked, yes, bootloader unlocked, no (on Sprint and everything other than the European model, no, EM model, yes), the rest of us, no, huge difference. I would pay a small fortune if bootloader unlocks were possible and why I bought the LG octoplus, still no option yet unfortunately.

Are you 100% sure this is not SIM unlocked using a modified octoplus (I have already gone down this path) so I bought my own octoplus. I am pretty sure all these "unlock" are merely SIM unlocks and not bootloader unlocks. I've investigated this pretty deep and it was only SIM unlocks not bootloader. As far as I'm aware, there is no hacks or mods to unlock the bootloaders for any LG G7 as of yet. eBay results are all SIM (which is simply using oct to apply the US-unkocked m ok model unlocking the SIM).
If you can find a REAL bootloader unlock method that works and unlocks my bootloader, I will PayPal you 20-30 bucks (I'm not joking). There is no method yet that anyone I know, knows of.

It's not sim unlock
It works by installing g710em bootloader and then flashing an unlock.bin .It's actual bootloader unlock. You can probably even do it yourself on a octopus box but I'm not sure what does it allow and not allow you to do.

If does exist, I can't find it on eBay or the internet, only SIM unlocks. I will keep checking but I don't see anything to unlock the G7 bootloaders.

Hey Piatch, i'm stuck on your same situation!
I have a new LMG710EM taken a month ago in a store, today with the Pie release (I'm in Italy) I found some time to unlock the bootloader, root, debrand (my G7 is TIM branded) and update to Pie.
I'm not new with LG, I come from G2, G5, G6 and now G7, never a problem (apart from the slowness in the updates I like them).
Well, just your situation, only the wording is a bit different, to me it says FAILED (Write to device failed (Too many links)) then the phone reboots and freezes in G7 logo and I have to press the power button to restart it, like yours.
I've tried everything, even reading online, different USB cables, different fastboot versions, but nothing worked.
Then I unbranded via lgup refurbish option to have a clean install and reinstalled all, thinking that maybe the new OS would solve but nothing, same message.
Can anyone help us?
It is the first time in several years that I have not found a solution.
Thank you in advance

I'm not new with LG, I come from G2, G5, G6 and now G7, never a problem (apart from the slowness in the updates I like them).
Well, just your situation, only the wording is a bit different, to me it says FAILED (Write to device failed (Too many links)) then the phone reboots and freezes in G7 logo and I have to press the power button to restart it, like yours.
I've tried everything, even reading online, different USB cables, different fastboot versions, but nothing worked.
Then I unbranded via lgup refurbish option to have a clean install and reinstalled all, thinking that maybe the new OS would solve but nothing, same message.
Can anyone help us?
It is the first time in several years that I have not found a solution.
Thank you in advance

Hi f0ster, I did not find any solution because I was lacking the time and tbh the skill to do it. I think we can't unlock the bootloader while under Pie ? Maybe if we roll back to Oreo, then we can unlock it and then update to Pie again ? I don't have the skills nor the confidence to safely flash Oreo on the G7 (I had bad experiences with bootlooping on the G3 and G4). Maybe you could try this way and see if it works out for you ?

Need Help with Locked Passcode on LG G7 (Mods: please remove if its in the wrong sec)

Hi! I have a friend that has an LG G7 ThinQ. Her husband just recently passed again from COVID and she's wondering if there's any way that she can bypass the lock screen so she can retrieve information from the phone.
The phone is OEM firmware. Any ideas or any specialist that I can refer her to? We are based in Los Angeles, CA.
Thank you very much in advance.

Sorry for ur friend mate.
A lockscreen from LG means that u Will lost all the data if u dont remember this. That says the text from LG before u accept the lockscreen agreement.
The oem software is blocked with encryption that prevents writing to /system and other dependencies. Even worse if the terminal does not have the usb-debuggin enabled, it will not be able to modify anything from fastboot or recovery. The only thing I can think of would be to flash from lgup the partitions that are needed to bypass the lock, but again the data partition I suppose will remain locked by encryption. You should contact LG Electronics to discuss the case as it is something exceptional and they could help you.
