What Is Bootloader?

An additional security layer must be unlocked to alter or modify your phone’s main software. Every phone has this protection layer; in the case of Android, it is called Bootloader, whereas in the case of iPhone, it is called iBoot. There are two levels of bootloader, Primary and Secondary.

The primary Bootloader is hardware-locked and can be accessed only after opening the phone’s body; only a qualified technician can unlock it (so it is better not to play with it if you are unaware of how to do it). Meanwhile, the Secondary Bootloader is software-locked and can be unlocked once the smartphone brand grants permission.

In the case of Xiaomi, Redmi, and POCO, earlier, the permission to unlock the bootloader was granted in a few hours. But now, according to the new policy, a user must wait 168 hours (approximately seven days) to unlock the bootloader to begin the flashing process.

Reason for the “MIUI Can’t Be Installed on This Device” Error

Now that we know what the bootloader is and its importance to be unlocked to flash any other ROM? Let’s learn why you are facing the “MIUI can’t be installed on this device” error. Xiaomi observed many people importing Xiaomi phones from China in large quantities, flashing global software, and selling the phone in other countries. This practice caused a huge loss to Xioami Globally.

That’s why Xiaomi decided to lock the bootloader if someone tries to flash another ROM on Xiaomi phones originally sold in China; another fact to be noted is that phones sold in different regions are customized to suit the market; this customization can be different hardware or different software. Flashing a ROM meant for another region may damage the phone due to incompatible hardware and software.
