DOwngrade OnePlus 8T - Possible? - OnePlus 8T Questions & Answers

Hello,
I have one OP8T 11.0.8.12 i want to downgrade. Is that possible?
THe problem is i have a Google account lock on it and i cannot use it.. So i try on youtube how to do but in this version is missing th Oneplus Switch. SO i was thinking if we can downgrade to get this app.

You have a phone.
You wish to downgrade the phone to a previous version, but you are unable to access the phone because it is locked.
Locked using an account you do not have control over.
Unless you add a little more detail, what you are describing is the sort of situation one would be in if they were in possession of a stolen phone.

Is there any solution for the bypass of the Google account?

Xiaomi phone - forgot lock screen pattern, now I cannot log into it

Hello all,
My sister recently bought a Xiaomi smartphone for her 12-year old son. But after just a few months, her son forgot the lock pattern that he had use on the phone, as he was constantly changing it.
So, now the phone is working Ok, but we cannot log into it, as we do not know the pattern.
We have his credentials for the google account, and the Xiaomi (Mi) account.
However, t here is no option to use them to unlock the phone.
We also tried to contact Xiaomi, they asked for the Mi account credentials, and after we provided these credentials to Xiaomi, they sent us an SMS with a code...which did NOT work!
So, I don't really know what to do, except to us for help, as none of us is very technical.
I found this program (Mi account unlock tool), but since it is not an official Xiaomi program, I am scared that maybe it is a virus or something like this - do you think I should use it?
If not, then how can I unlock the phone?
I am OK with doing a factory reset, and losing all settings and data that are currently on the phone, if that is necessary.
Also, please note that when I press the power button and the volume up button, I do NOT get an options menu, I get a picture with a phone and a usb cable - probably the phone wants me to connect it to the computer, but I am not sure about what the next step should be.
Does anyone have any suggestions?
Thank you

Question about: Unlock OEM with bypass

Hi there, I have question. I buy new motherboard for my phone, and I was needed to bypass the google security because I dont wanna buy whole new phone because one part.

Changing lock screen owner info

It doesn't appear to be possible to change the lockscreen owner info on ColorOS, but it's imported from my previous device during the setup restore process. I need to change it since the phone number on there is no longer correct, but I can't without resetting the device!
Does anyone know if it's possible via Dev tools or ADB?
I have the same problem, but on a realme device. The date is 2023.01.14. Do you have a solution?
The only solution I found was to buy a Pixel 6 Pro
Exactly the same here with an Oppo Find X2 Pro. My owner info has been imported from my old Huawei P20Pro, 3 years ago. It was at first time visible. It disapeared from the screen with an update (Android 10->11 may be ?), then it re-apeared again with ColorOS 13.0 (ie Android 12->13). But still no way to update it...
I think Google should give access to it through the cloud syncing of phone parameters. I'm also lookng for an ADB way to update it, but my phone is not rooted.
Bad luck with this import

FRP - used phone, Google account, no PIN provided

After 10 years I really should know the answer, but I don't, and the XDA search function still doesn't work for me.
My N5 has a broken SIM tray. I bought an eBay broken-screen N5 and put this motherboard into mine. It asks for a PIN, which I obviously don't have (understandable that the seller couldn't remove the account, since the screen was totalled).
I've asked the seller for the PIN, but personally I'd be reluctant in his shoes.
Is there a workaround? I've seen the YouTube video (factory reset, settings, enable bootloader unlock, etc.) but that looked as if it was on an Android 5 device and I'd be surprised if Google haven't closed the loophole.
In the absence of a PIN, any suggestions? I've seen a suggestion that the seller could remove the device from Google via his PC - would that work?
(Edit: No, the seller says that the device doesn't appear on his Google device list.)
Thank you...
Update to prevent anyone spending time trying to think of a way to help...
In fact for reasons which appear to go against everything I've read about FRP I was able to use Fastboot to boot TWRP and factory reset the device, after which I was able to install CrDroid. Maybe it's because the device was on Android 6, too old for FRP to be a problem.
Anyway, bottom line, all ok now.

FRP lock

Hi,
Is there a working method or software for removing FRP lock from a Pixel 2, latest update?
None of the ones online I can find work anymore.
Context: I purchased a 2nd hand phone, but the seller forgot to remove his google account before resetting it and its proving complicated to reunite him with the phone so he can enter his details and remove the lock. He suggested I look into ways of removing it.
Thanks,
kami

I have no idea if this works, but you could try this...
Be VERY careful with any method that suggests downloading files. FRP unlock/bypass is one of those "gray areas" where you're likely to run into malicious software.
