[Solved] Lost pin code, no recovery, how do I reset mi 5?

Hello,
I've bought a Mi 5 to my son and he changed the lock screen pin code and subsequently fogot it. Now, without being able to get passed screen lock login, without a recovery, how do I factory reset the phone?
I'm unsuccessful in unlocking the bootloader, the device (Mi 5) is not attached to the account. This attachment is done in the settings which I cannot access because I do not know the pin code.
I've found this article, but no response has been given yet : https://forum.xda-developers.com/mi-5/help/mi-5-dead-factory-reset-t3379029
How on earth do I reset the phone? Does anyone know how to do this?
Please please please help me out...
//Jan Stenvall
PS This is a cross post with this article, Ill update this post with whatever finding I get. http://en.miui.com/thread-1016219-1-1.html
Answering my own question:
Warning, this will erase everything on your phone, it's a factory reset.
Connect to your google account, use Find my phone, choose the device and continue logging in. Choose Consider erasing your device, then click Yes.
This will erase everything on the phone and will enable you to access the phone again after reinstalling.

Stuck on process of unlocking bootloader

Hello guys, I know there is a LOT of these threads complaining about bootloader unlocking, but I have tried everything that is available on the internet and not being successful. So I have been trying for around months to unlock the bootloader on my mi5 phone. I asked for permission and it was given the next day. After I have the permission, I:
Enabed developer mode
Enabled oem unlock
Enabled usb debugging
I used the old MiFlashUnlock_1.1.0317.1_en, the unlocking process stop at 50%, it tells me to update the unlocker tool, then I decided to download the newest miunlock 2.3.803.10, now I succesfully verify my device and go up to 99% but this time it tells me "Current account is not bound to the device" and ask me to go to Developer Options > Mi Unlock Status. Then I go to "Mi Unlock Status" and it says "Couldn't verify, wait one minute or two and try again". Another error.
Things I have tried:
Tried global stable rom
Tried global developer rom
Wait few more days (even months)
Tried VPN to china
I have tried literally everything, what do I do now? I read somewhere people say you dont need to bother about the "mi unlock status" just keep trying till you succeed.

Probably a stupid question, but after going to the developer options -> Mi Unlock status, have you entered your email address and password that you used to ask for unlock permissions?
It is some time ago i have done this, but you need to connect your account (email and password it was, i think) on that page, and after that you can use the PC program to unlock and there also use the same account settings.

After I click the "Add account and device" button, it just directly says "Couldn't verify, wait one minute or two and try again". No chances to enter the account details. But actually I have already entered my mi account at the accounts section in setting. Thank you for trying to help
I am also facing exact same issue on my Redmi 5a (riva). Please let me know if you were able to find any solution
anyone fixed this problem?
Anyone can solved this problem
exact same issue here on Redmi Note 4X -
Can't bind the account to device in Developer Options/Mi Unlock.
Error: "Couldn't verify, wait one minute or two and try again"
Is there anything that could block the connection to Xiaomi servers?
Please check (software) firewall, anti virus and router settings. Also try alternative DNS such as Google DNS or Quad9.

is there anyway to unlock bootloader without permission on miui 10?

One of my friend has redmi note 3 kenzo
It would be very helpful if someone has a trick to unlock bootloader without permission.
I think there is no need of permission for old devices for unlocking bootloader.
One of my friend has Redmi note 4X and was able to unlocked without asking for permission.
even this worked for his Redmi 3S but with 72hours of waiting time.
Just logged in into Mi unlock tool with same account as in device and your friend should be able to unlock bootloader (maybe not right away but with several hours of waiting time)
Problem isn't that
Problem is :- He is not able to add his mi account from developer option for oem unlocking.
An error occur always.

Yes, right. Log in in Mi unlock tools on PC with the same account as in the phone and then connect phone in fastboot mode but first make sure oem unlock is enable and usb debugging is turned on. ignore the account log in in phone.
just give it try.

Log out of mi account in your phone, log in again, associate that account with your device then try unlocking the bootloader. Worked for me that way.

Don't be confused. Older devices are unlockable without even applying(i am saying this on my experience) i have unlocked two of my friends Redmi 3S and Redmi note 4X without even applying to xiaomi.
never devices needs to have permission to unlock and it takes time and request can get rejected if the it does not meet their conditions.
if you have old device such as more than a year or more.
Just download and install Mi flash tools and you are good to unlock but it still shows error of 50% or stuck at 99% so you'll have to unlock after remaining hours which will show on mi unlock tools.
I just used this method to unlock my Mi Max 2, Miui 10

Its most likely server error from xiaomi as it happens many times and almost everyone faced it whoever tried to unlock i guess.
Please try again later and if possible try and connect to different WiFi network before adding account.
Also you can just give it a try by enabling USB debugging, oem unlock turned on from developers options and then just turn off your device and boot into fastboot mode and try unlocking it, regardless of adding mi account.
You should also try some different versions of mi unlock tools(preferably older version).
As i have mentioned it worked without even adding account and it took 3 days to unlock as it was getting stuck at 50% or 99% and was asking to wait for 72 hours and later it unlocked in first try so this should work for you too.
There is unofficial way to unlock bootloader please search on XDA/YouTube or some other websites.
I am exactly facing the same problem please help
Dear friends i done all this
Sinin sin out
New mi account
And other stuffs
But none of them worked
I have redmi 6A

See. This is why you should flash WITHOUT locking BL in MiFlash, if something goes wrong u can do it again but if you have locked BL, then you probably need to use EDL

I wasn't able to solve any problem with the EDL point yet. Sorry to say that. Therefore, as Marcelsky said, don't lock your phone by flashing. Pay attention to the button in the Mi Flash. Otherwise may the phone stuck in the bootloop, or will not start and ..

Unlock Xiaomi redmi 9

Hello, in need of some help.
I am having a great deal of difficulty in unlocking the bootloader on my Xiaomi redmi 9. I've completed all of the steps that Xiaomi ask customers to do and that any expert I've seen on YouTube doing. But after two weeks I still can't even get to the dreaded wait two weeks to unlock stage, if I could then I'd be a happy man!
I've got developer options sorted, turned on oem and debugging, linked my account to the mi unlock in developer settings, device found and on. Also updated drivers on my windows 10 laptop, signed in to my account on the mi unlock program, set phone in fastboot and then the unlock program verifies my device, but at 100% it keeps on giving me the same response ( please add your account in miui's settings-developer options-mi unlock status) which is crazy because I've completed all of the required steps and then some more steps to try and get past this can't unlock message. Also tried older versions of the unlock tool, but no luck.
Any help with this would be greatly appreciated, or a direction to go in to help me unlock the phone. I've contacted mi customer service for help, but they keep sending me the steps that I should follow to get unlock status and I've tried this a thousand times!
Bootloader unlocking guid/ Binding Account
First signout mi account,
Then reboot phone,
Then open developer option and click on
mi unlocked status
Then add your account here,
Now it's successfully binded
Then rest of the process do with laptop or computer
Hi, thanks for responding. I've just tried that and unfortunately it's the same outcome, 'couldn't unlock'

Thanks for the help. So I've bought a phone to root and it looks like I've bought the only one in the world that you can't even unlock the bootloader on ??*. I wondered why I couldn't find any more information. The phone is still under a month old, I might see if I can return it, ffs!
same here was happy about the price 101€ only but now i will return it too... i don´t want to have a phone without root

I had the same problem as you described.
Today, I did log off my MUI account from the phone settings and logged in again.
I started "mi unlock status" under development settings and added my phone.
Booted into fastmode and started the mi unlock program and got the message "please wait 168 hours ..."
In the past, I did always receive the message "add your account in mi unlock status"
I'm not sure, what did the trick:
logoff and login or just had to wait, that xiaomi fixed their unlock process.
Hopefully, I will get the phone unlocked in a week.
*fingers crossed*
I received information from the technical support that only one phone number must be active on the smartphone, the one assigned to the account. Secondly, if it still does not work, try several times until it shows the time to unlock.
It worked for me.
successfull unlock

Hello, thanks for your info on the 168 hrs wait. I went back on and tried again and got the 168 hrs wait too. I messed it up the first week and must have signed out, so I had to wait another week. Anyway unlocked now, but I'm having just as much of a problem trying to flash twrp to my phone. In command prompt every downloaded file I've tried and used won't recognise the prompts, can't get past the prompt fastboot devices or ADB devices! So can't find my phone to enable flashing twrp across and in turn I can't root my phone! It's driving me nuts.
Usb debugging on
Ptp selected
Windows drivers find my phone
But still having problems when trying to use command prompt in platform tools ?
lock
How can I lock it again ?
i have waited 168 hrs now its telling to wait 168 hr again...what can i do
the answer is,you have to wait,or contact xiaomi,lol.

Redmi 4x unlock

Hello,
As second phone I've got a Redmi 4X from my father. Phone cames with the China ROM, I would like to upload the Global ROM. In order to do this I've got to unlock the phone.
On Dev options, Mi Unlock Status function, I always stuck on the message "Don't disconnect from the network, sign out of your Mi Account, perform a factory rest, or erase system data. If you've already done any of the above, add your Mi Account again; otherwise, you won't be able to unlock your device."
I've try what the message says, no luck.
I suspect it's something blocked on the Xiaomi servers about this phone. Anyone can fix it?
Thank you!
I've solved putting the phone in EDL mode using the test points on the board.
