I managed to find a working solution for bypassing the "Today's limit reached" error by unlocking the bootloader (global ROM). Today, I received permission to unlock two phones hyperros 14T 13T I have at home using this method.
The solution is not mine, but from the link:

DOWNLOAD AND INSTALL
1. Extract the attached script
2. Python +(AQLR.7z)
3. Firefox and the Cookie Editor add-on
4. Chrome
INSTRUCTIONS
Get the cookies a short while before running the script (30 minutes max). Cookies are your session time on the website and expire the same as your session. The steps for getting cookies can be done on your mobile or PC.
1. Open Firefox and log in with the account linked to the mobile you want to unlock using link1 or link2. It doesn't matter which one you use; use one of the two.
Open the Cookie Editor add-on, search for "new" and expand the "new_bbs_serviceToken" section. Copy the token that appears in the Value section and paste it in positions 1 and 3 (deleting the numbers 1 and 3) of the token.txt file.
2. Open Chrome and log in as before using link1 or link2. Enter the following in the URL bar:
javascript : (function(){var token=document.cookie.match(/popRunToken=([^;]+)/);if(token){prompt("Copy the token:", token[1]);}else{alert("Token not found");}})()
*It is very important that you remove the space between "JavaScript" and ":" after pasting it in the URL bar.
Copy the token it gives you and paste it in positions 2 and 4 (deleting the numbers 2 and 4) of the token.txt file.
3. Run Script.py, enter 1, and press Enter. Without closing the previous window, run Script.py again and enter 2. This will open up to 4 windows.
DONE! Now just wait until 00:00 Chinese time and the script will run automatically.
It's very important that no matter what the script results in, you should ALWAYS do the following on your phone:
Settings » Advanced Settings » For Developers » Mi Unlock Status » Link Account to Device. Try unlocking with Mi_Unlock.
If that fails:
Settings » My Account » Sign out of Account » then restart the device;
After restarting: Settings » Advanced Settings » For Developers » Mi Unlock Status » Link Account to Device. Try unlocking with Mi_Unlock.
