@MiBoi9000 @xMarvin732 Maybe this can give you a hint: https://xiaomi.eu/community/threads/frequently-asked-questions.73215/
"I can't connect my Xiaomi phone with my Xiaomi tablet"
1.0 simply means that it is the new version numbering of Xiaomi after the end of MIUI 14: HyperOS 1.0 instead of MIUI 15.
Nothing more and nothing less.
Unlock the bootloader and flash thsi custom ROM or official Global ROM.

@kahntran What does your pad have to do with this forum? Nothing, it is not supported by this CUSTOM ROM.
So please address your issue/question at official Xiaomi forum.
You are on Global ROM and rporting your issue as a bug in a CUSTOM ROM forum? Why? That makes no sense.
Please address your issue/question at official Xiaomi forum.
With a custom ROM like Xiaomi.eu you must NEVER EVER lock your bootloader, otherwise you will turn your device into a brick.
Installing a ROM from Xiaomi.eu will never automatically lock your bootloader.
