LG H871 Google Lock won't let me log in! - LG G6 Questions and Answers

I was the last person to use this phone and have since kept it on the shelf, but recently I wanted to give it to a friend. The thing is that I signed in with my Google account and it says that "Please sign in using one of the owner's accounts for this device." I previously bought this thing on eBay but never had any difficulty with it until now. Is there anything I can do?
Thanks!

Advice urgently required -

Hello,
I need some urgent advice concerning a used moto x play I had recently purchased from an associate.
Last monday, I heard news through a friend that another mutual contact was selling his moto x play. I contacted said person and asked if I could come over to his place to quickly view the device. He was selling it at such a bargain price, and I contemplated purchasing it with a view to gift it to my 13 year old niece as a present.
anyhow, as I was viewing the device, I wanted to check to see if everything was working in order, so I switched it on, and i realised it had already been factory reset, so in order to quickly review the screen quality and functions, I made up some details (email/password) on the spot in order to gain access to the device home screen, as I didnt want to input my own details just in case I decided I was not going to buy it.
I had connected to the wifi at the sellers apartment, and I began to review the device, and everything seemed in full working order, the screen was bright and vibrant, no yellow hue, it seemed slightly snappy and lag free etc, the wifi was working etc etc.
So I ended up purchasing it by cash.
The device was left on the side in my office until Wednesday, where I fully charged it, and i conducted another factory hard reset. My intention was to initially create a new gmail account for me niece as she has never had an android handset before.
After the factory reset had been completed, I was expecting to be put through to the standard android set up screen, and for the first few options, everything seemed to be fluid. Country, Wifi set up, motorola security op in/out, and then i came to the google account screen.
All that was stated was that ''This device has been reset, please enter account details of previous account''. I was not sure what was going on, so I contacted the original seller, and he was also confused, and he asked me to pop over during the evening.
I went over after work, and he attempted to enter his details, and they were not being accepted? We hard reset the device 3/4 times including wiping all user data and personalised content etc, and it kept asking for the credentials of the previous owner. My friend then made me aware of the made up account details i had initially used the day I purchased the handset from him, but I have no idea what these details were. I literally made them up on the spot without making any notes on what they were. I have successfully done this before many many times? Especially when reviewing second hand devices before buying.
Since Wednesday, neither me or the seller have been able to find a way around this. I have searched online high and low but with no help.
Can anybody please advise?
Try doing clean wipe through recovery instead
Have tried to wipe data around 4 times now. It erases, then, for some reason, its still asking for previous account credentials?
Is this some sort of new security implementation from google?
I would just flash it back to factory defaults...
Contact Motorola
Search for bypassing that security. I think it's called Google reset protection or something like that. And it's present in 5.1. Sorry I'm traveling right now and can't research much the web for that. I believe that in the Motorola Moto X Play's forum there was discussion that someone actually did bypass that... And there was a video.
edit: It's called "factory reset protection"
Here's the top in on Motorola's forum

I've never had any experience with this, but I hope to help

If you can't bypass that after numerous tries, flash the stock firmware again.

Sign into google account after reset

Hello. A have bought a phone from Ebay, and cant sign in to google account due to security reasons (thanks google)
Contacted the seller, to provide me his acc/pass, but its useless. I am getting the same error. Can some1 help me solve this problem please?
Sounds like you purchased a stolen device.
This is FRP, Factory Reset Protection, and it's new on Lollipop/Marshmallow (can't remember exactly)... If a device associated with a Google account is factory reset, you MUST have the Google account credentials that were on the device prior to the reset to use the device again, a simple yet effective theft deterrent but can be a problem for consumers uneducated to it in the secondary market.
It is a very similar to approach to how Apple has done it for years and Windows Mobile has adopted a similar concept with Windows 10 Mobile.
On a few devices there are work arounds, but I am not aware of a working one on the Moto X.
BTW, if the seller changed his password or security method (like turned off 2-step authentication) recently, the phone is locked out even with the correct credentials for 24-72 hours depending on security patch applied to the device.
Oh, and a super simple way to avoid this... Delete all Google accounts on the device prior to a factory reset and wait a couple minutes (ensure you have an active Internet connection) then perform the reset.
i supose thats is becose the seller turned on the 2 step autentification.
idk, should i wait those 72 hours? or mby contact motorolla support?

Up to you, but Moto/Lenovo won't help at all since you are not the original owner with a matching serial number receipt. No one will or can help you except the person who know the Google account and password that was on the device when it was reset.
The whole point of FRP is it isn't capable of being bypassed, even by the manufacturer, otherwise what's the point of it? If you could definitively prove ownership to Moto they might help, but you can't since you were not the original purchaser of the device and you really don't know what happened to it before you got it.
Unfortunately, unless the seller can be of assistance or is willing to take it back, you're pretty much out of luck. You could file a PayPal claim against the seller if they won't take it back and the device was not as it was presented in the listing though.
the seller provided his acc/pass for the device, i have even the original purchase receipt (amazon.it)
btw. i have contacted motorola support, and they said to wait 72 hours, then to try to log in again

Then things are different in your country than mine... Moto won't even talk to someone in FRP who isn't the original owner. Good luck, hope it works out.
Just because the device has prior credentials on it, doesn't mean it's stolen. In fact I would the majority of the time it isn't, but all the "experts" on these forums offer that as their only advice, because really they don't have any idea how to bypass. Thanks "experts"

And as always, sign out of you google account before any reflashing of any kind of new or resetting default factory resetting the OS. Recovering the OS through TWRP does not require sign out of the google account.

Accidentally locked my phone after factory resetting...

Long story short, I bought a used phone and used a fake/throwaway gmail account to access play store to download an app to test everything was working. I then factory reset it not knowing it would then be locked until I logged back into that gmail account that I now don't know the username for!
I've tried a few of the youtube tutorials, but they either don't seem to work on this phone, or they require a special cable that I don't have.
I guess my only options left are to install a custom rom, but I am a complete newbie, I actually had to google what a custom rom was, but all the guides I find for doing this also don't work on a locked phone.
I feel like I keep going down different roads that all lead to dead ends
So does anyone know what would be the easiest way for a newbie such as myself to unlock my phone? And/or what guides could I use that would work for this phone?
In case it matters, I do have the original receipt (although not in my name) where the phone was purchased (from amazon), and the phone even has another 6 months left on warrenty. But I am guessing that would require posting the phone to LG and waiting weeks. Any better ways?
Did you set up a recovery email/phone number with the Google account?

Is it possible to change the IMEI number? (need help with my stolen oneplus6t)

Hi there everyone,
Last friday I got robbed in the street, the thief took my oneplus 6t with all my personal data, pictures... etc. after that I went inmediately to the google option "find my device", but, unfortunately, it was already turned off. Of course I went to the police and gave them the IMEI number and all the details about my device.
After that, a day later, I got in my google account again to check whether my phone was found or not, then I realized that there was a new phone (a oneplus 5 which I never had) logged in my account with a new IMEI number. I didn't do that, of course, so I'm wondering if it's posibble for the thief to change the oneplus6T's ROM into an another oneplus5 without unblocking it, getting a new IMEI and having a complete useful device. And, should I go to the police again to give them the new IMEI number in order to register it as a stolen phone again??
I don't have lots of expectations about recovering it (I didn't see the face of the guy who stole it), but anyway I would like to make that phone unusefull for them. (the device was stolen in Valencia, Spain)
thank you so much.

Nothing is impossible for IMEI
With the right tools and knowledge the IMEI number can be changed, it is illegal to do in some countries. You did the right thing to tell the police about the new number. Make sure that you update and verify all your passwords in google and all your other services. Make sure to remove any permissions from your old 6T on your services. Also, report it to carrier.

Even if he didn't change the IMEI number of your device, he could have used your phone to login to a new device using the tap-a-number feature.
Along with changing the passwords, I would also suggest logging out of all your devices.

Device locked by former owner's Google account?

Hi there,
It's been a longtime I didn't post out there.
A couple of weeks ago, I drowned my Galaxy M31 (bummer!), couldn't revive it. Being broke, back to my good old dumb-phone I use while skating (it's OK, actually).
A nice colleague of mine proposed to lend me her old Galaxy S7 she replaced a while ago by a newer device, telling the battery is a bit lazy now... Thanks to her.
In front of her, I reboot in recovery (she didn't even knew there was such a thing), factory reset the device and off we go.
Back home, I flash the last available Oreo firmware (just to be sure, with the CSC part), let it boot and... yeah, Google detects the device was reset and ask for the previous owner's account, as far as I understand.
It's OK, it is to trick robbers stealing phones and trying to flash them anew, I suppose. Got two phones robbed, encrypted and all, I hope they were f*** with mine.
I feel like... a sucker, I should have been more cleaver and probably ask her to delete the Google account it was registered to (hers, her husbands)
Can someone please tell me if it is the right way to do it right?
Never had to do anything like that: so next Monday, she sign in with her email or phone number, her Google password, the device goes on booting/configuring skipping whatever time consuming setup, up until she's able to "cancel" or delete the Google account?
Thanks in advance.
Hi there,
It took some time, lack of actually, to get it unlocked by my friend. The device is back to me and running Oreo on my account.
Let's root it and probably upgrade it to Lineage 17 or 18 as I did with an good ol' A300FU.
