# AC46 Firmware Tool > AC46 Firmware Tool unpacks firmware images for JieLi AC4600/BT15 devices. It accepts a dumped flash image or a BFU file with its first 512 bytes removed, detects an encryption state, extracts bootloader and resource files, and writes a repacking batch script. The repository also lists cipher, CRC16, and chip-key utilities. - Type: Tool - Targets: Firmware - Category: Firmware tools - Relationship: Foundation tool - Sources reviewed: 2026-11-06 - Added to the catalog: 2026-11-06 - Original resource: - Primary source: - Catalog page: - Record JSON: - Chinese version: [简体中文](https://awesomerea.org/zh/resources/ac46-firmware-tool/index.md) ## Requirements & limits - A flash image from a JieLi AC46/BT15 device, or a BFU file with its first 512 bytes removed, is required. - Repacking requires an AC46 SDK. - No licence file in the repository. ## Primary sources 1. ## More in Firmware and hardware - [Bin X-ray](https://awesomerea.org/resources/bin-xray/index.md) · Tool - [PIC microcontrollers disassembler](https://awesomerea.org/resources/pic-disasm/index.md) · Tool - [premium5](https://awesomerea.org/resources/premium5-radio-emulator/index.md) · Tool - [SPRD Flash Tool](https://awesomerea.org/resources/sprdflash-rs/index.md) · Tool - [PCM Explorer](https://awesomerea.org/resources/pcm-explorer/index.md) · Tool - [ThinkPad IMX471: recovering camera tuning for Linux](https://awesomerea.org/resources/thinkpad-imx471-camera-case/index.md) · Case study ## About this entry The description was reviewed against primary sources.
