Can you see RMM STATE: Prenormal in download mode?

You're Prenormal.
You will have to wait 168hrs without rebooting your device before OEM UNLOCK will appear.

After working 150 hours without disconnecting the phone, OEM look at the option of the developer, I worked as a router and got a malfunction in the aluminum and then I worked to adjust the factory and it worked. Should the OEM disappear? Will it appear again or not in the download mode? RFP: OFF and OEM: OFF.
OEM knowledge: OFF bearing ricky rectifier is given as wrong as the first time before OEM show
If you wait 150 hours it will show again OEM

I don't think you can downgrade your bootloader, I think the only way is to install the next developer preview bootloader and then you would be able to downgrade it to an earlier version
CF autoroot has bootloader unlock option. worked for me when I had to unlock my bootloader after nougat OTA update in order to root.

adb work fine, fastboot work fine
My phone is in factory reset protection, and that's why I don't have access to the menu to access the developer options, usb debuging and other necessary .

He has a N6 where he's locked out of the device and unable to activate it. Either he forgot the email addy and password he used to activate it, or he purchased a phone from someone else and got locked out because that someone else didn't remove their account from the device prior to selling.
In any event, his legit options are to try and remember the email and password used, or to try and get the seller to remove their account from the phone. Otherwise he'll have to try and bypass the FRP.

as you do the factory reset bypass protection, you need to do a downgrade to an older version android, then bypass, and update to the latest version

I tried all solutions for bypass and other sources after youtube, but as the nexus the whole time comes the first time Android the newest and latest security patch, if I remember correctly at the October 5th when it came out the official version 7.0
@bombonel: With Factory Reset Protection in play you must know the email address and password used on the phone in order to progress in the setup. Entering into the bootloader in the phone's current state and attempting to unlock the bootloader using fastboot will not work. Unless you can get into Android and toggle the Enable OEM Unlock option in the hidden Developer Options menu you will not be able to unlock the bootloader.
Your available options are as follows.
You need to know the email and password used on the device.
If the device was purchased used from another person, you need to contact that person and have them remove the device from their account.
You need to start looking at methods of bypassing Factory Reset Protection.

I talked to the person from whom I bought the phone arrived in this State, the person from whom I got did not know how long does factory reset after 5 minutes of thought got stuck and enter to recovery ans wipe data and cache wipe, having the account and all saved and knowing that the first boot takes thought and got stuck and to give it to me , started that night fix to change the password to your gmail account and deleted and sync and all of his account and the phone became useless. Because it communicates with google server over the internet, but only synchronized with the old account and no password only, and tried to contact the folks at google and with whom you can, but make no result if the wrong person irreparably.

N950F bootloader issue

For mentioned model i do not get any type of Bootloader interface detected as hardware in device menager. Which also means i can not access it from adb in order to unlock bootloader. I have found some talk about switching into Unlock mode from Odin mode but can not find a way to do it. This also happens while i did USB debbiging and OEM unlock set on. I have latest Pie on it if that makes any difference.
I hope anyone has some advice on how to solve this and that you in advance

Go into developer options and toggle OEM unlock on. That's all that is required on Samsung's.

The TWRP you are trying to flash is for the N950F only.

you bet. that was the method a while ago at least. also, look for zip files you can flash in TWRP to make it to where that stupid 168 hour thing never pops up again. I think it was called the Chimera tool or something like that. and be sure to use the thanks button when someone helps you

General What not to do with China ROM

I recently got the phone and i have the China version 12/256. Here are few things to take care:
1) Install Google Keyboard first before debloating system apps using adb.
2) Very Important: First update the phone to latest firmware (12.0.13) before you toggle the OEM Unlocking option in developer settings. If you dont update first and have the option toggled and try to install an OTA update the phone will just bootloop unless you clear the data and sign in with mi account again. This will reset the 168 hours time in the software. So always update the phone to latest update.
3) If you are using google pay, go to nfc settings and change the wallet from Mi Wallet to HCE Wallet.
4) The stock TPU cover is loose on the sides. I dont know if its just mine. But better buy another case from aliexpress.
5) DO NOT install global stock rom through fastboot or mi flash tool. It just wont work because of the different versions(regional) of phone. Only install xiaomi.eu ROM using the guide from a post on xda because the install script knows which version your phone is and installs the appropriate system files.
@ingbrzy can you confirm that? :

It is safe to install. haven't installed it yet but read on forums that it is working.
so I guess
1) unbox your phone
2)update to latest software via settings.
3)factory reset device after that.
3)request bootloader unlock.
4) after 7 days, unlock your bootloader and tooggle that OEM unlock
5)follow instructions on xiaomiEU rom.
is that safe enough? Lmao
PS:
6) Find EDL support near you

3) Enable Developer settings, Developer Settings> Toggle OEM Unlocking
4) Turn off Wifi, Turn on Mobile Data, Settings> Additional Setting>Developer Settings> Mi Unlock Status> Click Add Account and Device.
5) Download Mi Unlock Tool, Login to same mi account > Turn off device, Hold Volume Down and Power Button ( you will see fastboot screen)> connect the device using USB, You will see the device, Click on Unlock button.
6) It will show wait for 168 hours to unlock.
7)Do not sign out/ change mi account on device or toggle the OEM Unlocking option. If you do you have to start from the beginning.
If you dont see your device in Mi Unlock tool install adb and fastboot drivers.

It seems to be working fine but I need to go outside and test the 5G and 4G signals are still as good as before
It's definitely feels much lighter and smoother
WhatsApp notifications are working properly
There's much less apps in the drawer, Chinese was very bloated , now there's not a Chinese app or character to be found!
Also banking apps are working fine!

Please post the instruction how u did it. With full info
Just downloaded and install it from a Windows laptop
You have to wait 168 hours to unlock it and then open the phone in Chinese language to get to the developer options again before you flash , you need to enable usb debugging again!!!
You will need wi-fi to get back in because there's a security check after unlock, it maybe in Chinese but you will figure it out
I had never used a Xiaomi phone before this one , there are literally no downsides anymore....
I'll update if I can find something that doesn't work

Can you explain the technical reason and the source of the information when you claim that you must update to 12.0.13 before toggling OEM unlock.
I started my unlock last week and I have 12 hours left. 12.0.13 was not out last week. So, obviously I toggled it before that.
Can you explain why 12.0.13 specifically is required before toggling OEM unlock?

Because my phone went into bootloop. I updated to 12.0.10 and then toggled the OEM Unlocking. While i was waiting for 168 hours, i got 12.0.13 OTA update and i tried installing it. Phone restarted 3-4 times and took me to recovery. I then wiped data and it started again with a factory reset. So iam just warning people to get the latest update before doing this. Also, i do own a POCO F2 Pro and i am quite experienced with flashing ROMS. Developers always ask you to update to latest firmware before flashing as the new ROMs are based on latest firmware.
Xiaomi.eu is not a custom AOSP ROM but just a word of caution.
Sounds like after OTA 12.0.13 phone should be a factory reset it

Dear Friend,
I am having issue with S21 Ultra which i purchase just 2 months ago.

After searching XDA forum and Google all the setups mention there i have tried to visible OEM Unlocker option but OEM lock option never visible. Even flash stock rom again and again and wait for 168H but still its not visible.
When i go in download mode and try to flash TWRP or any custom rom it show below mention msg.
"Cause

Please suggest what option i have left to resolve above mention issue.
Could you try to flash latest Stock rom(Via odin) and try again?
