Redmi Note series has been immensely popular in the market and has been one of the hottest selling mobile series from a smartphone brand. The Redmi Note 7 series followed by the Redmi Note 8 series were quickly among the best sellers list and now we have the Redmi Note 9 series.
The Redmi Note 9 series in India carries three phones under its belt. The Redmi Note 9, Note 9 Pro, and the Note 9 Pro Max. A max version is something this year and carries some changes over the Redmi Note 9 Pro. While the Note 9 is powered by a MediaTek chip, the Note 9 Pro comes with the Snapdragon 720G.
On paper, both the models are decent for the amount of money you shell out. In this post, we will guide you through the process to unlock bootloader of Redmi Note 9 Pro and Note 9 smartphones. But first, let us understand what a bootloader is and the reason why Xiaomi opted for locking it.

Why is Bootloader Locked on Xiaomi Phones?
A bootloader is a piece of code that restricts you from adding new code blocks to the OS. This is the first barrier that you need to cross, to start your journey with a custom ROM.

Xiaomi has encouraged its users to tinker with their products in the past but has come at a cost. Recently due to the surge in the demand and brand value, more and more grey marketers are importing and selling Xiaomi phones in countries where the brand is not officially present. Most of these phones carry unofficial ROMs containing bloatware. To mitigate this, the easiest solution for them was to lock the bootloader.
The other reason was to give the user option to track their phones in case of theft. Locking the bootloaders helps in making sure that a custom ROM is not easily flashed onto the phone. Hence making it difficult to sell off these stolen phones.
