BYD USB structure: BYDUpdatePackage and UpdateFull

For Multimedia USB flashes on Dilink 3, 4, and 5.0 (when the package uses msm8953_64), the Dilink tablet does not read a random ZIP on the stick. It expects this folder layout and a file named UpdateFull.

Same structure for all supported Dilink generations — only the firmware file must match your version.

Reference: Flashing method only for Dilink 5.0 23 chipset.

Correct path on the USB drive

USB (NTFS)
└── BYDUpdatePackage
    └── msm8953_64
        └── UpdateFull

Windows path string:

BYDUpdatePackage\msm8953_64\UpdateFull

BYDUpdatePackage — top-level folder required by this update channel.
msm8953_64 — platform folder (Qualcomm msm8953, 64-bit) for packages that use this tree — common on Dilink 3/4/5 Multimedia builds that follow this method.
UpdateFull — the update payload (renamed from the downloaded ZIP per the guide).

NTFS, not FAT32

Format the USB as NTFS. FAT32 sticks are a common reason the tablet does not see the drive.

Renaming the download

Download the package for your Dilink version from ModHub24.
Rename to UpdateFull — see step-by-step flash.
No extra nesting or spelling mistakes.

Quick verification before leaving the PC

Walk the path click by click on the computer.
One UpdateFull at the correct depth, non-zero size.
Safely eject before plugging into the car.

Wrong structure symptoms

See compatibility notes if the package might be wrong for Dilink 3 vs 4 vs 5.0.
