BYD India — App Sideloading Guide
India-specific guide. The native DiLink 3 USB installer differs substantially from Brazil/Thailand/Indonesia: it uses password 130820 and a narrow package allowlist.
13.1.33.xxxxxxx.x or 13.1.32.xxxxxxx.x. The method varies by firmware, chipset and vehicle; look up the matching combination before proceeding. This guide may not cover every combination.INSTALLATION METHODS
USB — Third Party Apps 91
India is a special case in the analyzed DiLink 3 configuration. The folder is Third Party Apps 91 and the local password is 130820, not BYD6125F.
Stock USB is package-restricted
The analyzed installer allowlist permits com.mappls.auto.bydznav23 (Mappls navigation). Arbitrary APKs such as DashArc are not accepted by the stock India USB policy.
Therefore changing only the folder name or password does not make arbitrary sideloading possible on an India-configured stock unit.
