Xiaomi Update security News By Techno Fayez

Xiaomi started rolling out an update in April 2023 that includes a new security patch. This update brings several changes and features that affect the functionality and security of Xiaomi devices. One of the major changes introduced in the update is the implementation of a new security measure that forbids the unauthorized unlocking of the bootloader. This is achieved through the use of eFuses, which are electronic fuses that can be programmed to permanently disable certain functions or features.

Additionally, the update introduces a new lock status checkup system, which utilizes two lock status levels. While the exact details of these lock statuses are not specified, it can be inferred that they are designed to enhance the security of the device and prevent unauthorized modifications.

Another significant change brought by the update is the switch in file systems from Ext4 to EROFS (Enhanced Read-Only File System). EROFS is a lightweight read-only file system initially developed by Huawei for the Linux kernel. This change has implications for bypassing the MI Account using methods such as blocking or replacing hosts files. With the adoption of EROFS, these bypass methods will no longer be effective on new Xiaomi devices.

It is worth noting that the information you provided specifically mentions the test device used for this update, the Xiaomi Redmi 12C with the Mediatek MT6769Z Helio G85 chipset, based on the MT6768 architecture. However, it is unclear if the mentioned changes and difficulties apply universally to all Xiaomi devices or are limited to specific models or regions.

If you have experienced any difficulties or encountered these changes on your Xiaomi device recently, it is advisable to consult official sources or the Xiaomi community for the most accurate and up-to-date information regarding these updates and their impact on your specific device.
