You cannot directly extract this from a random firmware .bin unless the firmware contains proxy rules. The tool will automatically sign and pack the
Because .bin is a generic "binary" format used by hundreds of different programs, there is no single universal converter.
Ensure you have the patch.xml or correct partition table mapped.
Converting multiple BIN files into a single PAC file makes the firmware compatible with official flashing utilities like the Spreadtrum Upgrade Tool. Prerequisites and Requirements
This is the scenario where a direct conversion is both common and often necessary. You might have a collection of individual BIN files (such as boot.img , system.bin , uboot.bin ) from a backup or a custom ROM and need to combine them into a single PAC file to flash onto a device.
