This paper is structured for an audience of advanced users, custom ROM developers, and firmware engineers working with Xiaomi/Redmi devices featuring the legacy Mi-recovery 2.0.1 environment. Document ID: XM-REC-2.0.1-UPD-001 Subject: Installing an Update.zip package to the system partition using Mi-Recovery 2.0.1 Version: 1.0 Date: October 26, 2023 (Retrospective analysis) 1. Introduction Mi-Recovery 2.0.1 is a legacy recovery environment found in Xiaomi devices released approximately between 2014 and 2017 (e.g., Redmi 2, Redmi Note 3 MTK, Mi 4i). Unlike its successor (Mi-Recovery 3.0) or standard AOSP recovery, version 2.0.1 presents unique constraints when installing an Update.zip directly to the system partition. This paper dissects the process, signature requirements, scripting limitations, and associated risks. 2.
