Original Firmware (Stock ROM): For the device you are working on. Step-by-Step Repack Guide 1. Extracting the Original File

The pkgunsptlistbin is usually found in the root directory of the extracted firmware folder. Locate pkgunsptlist.bin. Create a backup of this file before making any changes.

If the file is compressed or encrypted, use a tool like 7-Zip or a dedicated BBK extractor to view the internal contents. 2. Modifying the Binary Data

The primary goal of repacking this specific file is often to add your device's ID or a specific partition name to the "supported" list. Open pkgunsptlist.bin in your Hex Editor.

Search for strings related to model numbers (e.g., PD1602, PD1901) or partition names (e.g., system, vendor).

To add a model: Find an existing model entry and overwrite it with your target model string, ensuring you do not change the total file size (padding with null bytes 00 if your new string is shorter).

To bypass verification: Look for checksum values or "magic bytes" at the header of the file. Advanced users may need to recalculate the CRC32 or MD5 if the tool performs a self-check on the .bin file. 3. Reassembling the Package Once the modifications are saved in the Hex Editor: Ensure the filename remains exactly pkgunsptlist.bin.

Place the modified file back into the original firmware folder, replacing the old version.

If you are using a tool that requires a "manifest" update, you may also need to edit the .xml or .txt scatter file to reflect the new file size or checksum of your modified .bin. 4. Flashing with AFTool BBK 5.1.31 Launch AFTool.exe as an Administrator. Select the "Scatter-loading" or "Firmware Upgrade" tab. Load the scatter file from your modified firmware folder.
