Hi,

I'm trying to unlock my redmi note 5 with the latest version of miunlock but I keep getting this error message at 99%: "Request parameter error"

My account is correctly linked to the phone, I have no clue what to do...

Thank you!

Same here: Redmi Note 5 Pro and the last global stable Miui 11 Rom.
I have enabled in dev options oem unlock, USB-Debugging and bind my phone to Mi Account (unlock status).
I saw the popup, that the phone is bind to my account.
Mi Cloud find my Phone.

The Phone is connected with USB 2.0 Port.
I have try the newest and older versions of the Mi unlock tool as admin.
Every time the same at 99%: Couldn't unlock => Request parameter error
In the Device Manager (Win10) I find Android Phone and ABD Bootloader Interface.
I think it looks good.

I have attached the mi unlock tool log file.
Where is the solution and sorry for my bad english.
It is not my native language.

Thank you for comments :good:

I had the same problem when I used my second phone as usb tethering network connection, but I fixed by using it as wifi hotspot. The adb thingie was not "locked" or if you have other devices connected via usb, it get the error, I believe.

If someone is still wondering, just connect your phone in fastboot and open Minimal ADB and Fastboot. type this "fastboot flashing unlock" and hit enter. This did the job for me.
