Google has news on what you will need to do for still being able to sideload apps:

* enable developer options
* confirm that you are not tricked
* restart phone and re-authenticate
* wait one day
* confirm with biometrics that you know what you are doing
* decide if you only want unrestricted installs for 1 week or forever
* confirm that you accept the risks
* enjoy the few apps that still have developers motivated to develop for a user-base willing to put up with this

@grote I guess anyone willing to jump through all those hoops has already installed Graphene or Lineage or whatever.
*Cries in Redmi phones* (they're not allowing me to unlock the bootloader 💀)

@ziclaud depends on the device. My Redmi Note 11 took two attempts before I could finally unlock the bootloader, I had to wait 2 weeks because I clicked twice on the Mi Unlock tool.

You need a Xiaomi account, insert a SIM card into your phone, use that phone number for the Xiaomi account, then you can start the verification process. It's horrible, but it can be done.

@alextecplayz yeah, I did it with an older phone a few months ago to test it, a redmi note 8T, but my current redmi note 13 with HyperOS is wayy worse somehow. They say it's "bugged"...

@ziclaud oh god HyperOS, that one is a nightmare to try and unlock compared to MIUI. My condolences.

You need a 30-day old Mi Account, the Xiaomi Community App and have a Global device. CN devices running HyperOS can't be unlocked anymore, because phone unlocking is illegal in mainland China since 2022 when the government passed a decision to outlaw it.

And with it is the "quota reached" bug that requires you to apply for unlocking at midnight Beijing time. Hell, now you have to run some Python script or whatever, from a brief look through XDA Forums.
