By following the steps and techniques provided in this article, you can convert BIN files to PAC files and achieve your goals.
To convert Spreadtrum/Unisoc firmware files (often in .bin or .img format) into a single .pac file, you can use the Research Download Tool. This tool is typically portable as it runs directly from its extracted folder without requiring a standard installation. Steps to Convert .BIN to .PAC
Prepare the Tool: Download and extract the Research Download Tool (also known as the SPD Research Tool) on your computer. Launch: Open the folder and run ResearchDownload.exe. Load Partition Files:
Click the Settings (gear icon) to open the download settings menu.
Load the FDL1 and FDL2 files first by double-clicking the "FileName" column and browsing for your .bin files.
Continue loading other available firmware components (such as recovery.img, system.img, or logo.bin) into their corresponding slots. Configure Options: Go to the Options tab and uncheck Repartition. Build the PAC File: Return to the main screen and click the Packet button.
If prompted that not all files are selected, click Yes to proceed.
Enter a Product Alias (e.g., the phone model) and Product Version.
Click the browse icon next to Saving Path, choose a filename, and click Save. Step 1: Ensure each partition file matches the
Complete: Click OK and wait for the tool to finish. You will see a "Packing Complete" message once your .pac file is ready. Alternative: Infinity CM2 (For Specific Backups)
If you are using an Infinity Box CM2 backup (which uses the .pac.sc format), you can use the built-in FW Converter: Open Infinity CM2 SPD.
Go to Extra > FW Converter > Convert Infinity PAC.SC to SPRD PAC.
Select your backup file and choose a destination to save the new .pac file. If you'd like, let me know:

Many routers (e.g., older TP-Link, D-Link, Zyxel) allow you to save settings to a .bin file. This is not firmware—it's a compressed configuration archive.
To convert a .bin file into a .pac file (typically used for Spreadtrum/Unisoc smartphone firmware), you don't need a heavy installation. Most of the industry-standard tools are portable by nature—they run directly from a folder without needing a formal setup wizard. Core Tool: SPD Research Download Tool
The most reliable way to "packet" various .bin and .img files into a single flashable .pac file is the SPD Research Download Tool (also known as the Upgrade Download Tool). The "Packeting" Process:
Extract the Tool: Download the latest version of the SPD Research Download Tool and unzip it to your desktop.
Open Settings: Launch ResearchDownload.exe and click the Settings (gear) icon.
Load the Components: A .pac file is actually a container for multiple smaller files. You must load individual parts:
FDL1 and FDL2: These are critical loader files usually found in your stock ROM.
BIN Files: Assign your .bin files (like nvitems.bin) to their corresponding partitions in the list. Create the Packet:
Navigate to the Options tab and uncheck Repartition if you only want to update specific data. Click the Packet button. Enter a Product Alias (phone model) and Product Version.
Choose your save destination and click OK. The tool will compress your components into a single .pac file. Alternative: CM2 SPD Converter
If you are working with backups specifically created by Infinity Box (CM2), you can use the CM2 Converter tool. This is a specialized portable utility designed to turn the .bin or .sc files generated during a CM2 backup into a standard .pac format for easier flashing with other tools.

The fluorescent lights of the server room hummed a low, headache-inducing B-flat. Elias rubbed his temples, staring at the wall of text scrolling across his terminal window. It was 2:00 AM, and he was staring down the barrel of a deadline.
The client, a retro-archiving firm, had sent over a terabyte of data recovered from legacy surveillance systems. The problem was the format. Every file ended in .bin.
"They’re just raw binary dumps," Elias muttered to himself, taking a sip of lukewarm coffee. "No headers, no indices, just a stream of ones and zeros."
He knew what they were supposed to be. The client needed them in .pac format—specifically, the LibPAC archive standard used by their viewing software. A .pac file is essentially a container, like a zip file but with a specific header structure that tells the software exactly where one video clip ends and the next begins, along with metadata timestamps. A .bin file, by contrast, is a dump truck emptying its load onto the pavement; it’s just the raw material, completely unorganized.
Elias cracked his knuckles. "Time to build a bridge."
