BYD Europe — App Sideloading Guide

Guide for Europe-configured BYD head units. Unlike local-password regions, Europe is configured for online APK verification, so the normal USB flow can require BYD cloud/QR approval.

Do not assume a country code from the telephone dialing prefix. Use the code configured by the head unit. Europe has no single universal folder suffix.
Check your firmware version. Open Settings → System → Version / Software Details and note the full version, such as 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 — Application Installation {code}

European DiLink configurations are different from local-password markets. The installer uses BYD online verification rather than a universal offline password.

  1. Check the configured country code on the head unit.
  2. Create Application Installation CODE using that configured code.
  3. Copy the APKs to the folder.
  4. Insert the USB drive.
  5. The installer can request QR/cloud authorization instead of a password.

There is no single Europe-wide numeric folder code because Europe covers multiple country configurations.

BYD Europe backend

The reverse-engineered installer points European verification to apr-eu.byd.auto. Approval is decided by BYD's server. A correctly named USB folder does not guarantee that an arbitrary APK is approved.

Engineering menu / ADB

If the unit still exposes the IMEI engineering flow, dial *#91532547#*, generate the code with BYD Secret and enable ADB. This avoids relying on cloud approval for normal adb install.

adb connect CAR_IP:5555
adb install -r app.apk

Europe 13.1.33 — 2404 unlock path

Only use this route when the version shown by the car starts with 13.1.33..

  1. Download 13.1.33.2404.
  2. Prepare BYDUpdatePackage\msm8953_64\UpdateFull.zip on a FAT32/exFAT USB drive.
  3. After 2404 boots, pair Bluetooth and dial *#91532547#*.
  4. Use BYD Secret with the IMEI digits shown by the head unit.
  5. Enable Wireless adb debug switch and Debug mode when USB is connected.
  6. Install PackageInstallerUnlocked.apk, then install normal APKs from File Manager or ADB.
adb connect CAR_IP:5555
adb install -r app.apk
