And most importantly, how do you remove this inscription if it interferes?

In this article, we will discuss in detail:

• 🔓 What is Unlocked and Why Does it Appear on Xiaomi (Unlike Other Brands).
• ⚠️ Risks and benefits of unlocked bootloader - whether it is worth leaving or better to return everything as it was».
• 🛠️ Step-by-step instructions on how to hide an inscription (including formal and informal methods).

• 🔓 Getting Root Rights (Root) through Magisk.
