Firmware Decompilation Service - MikaTech

Firmware Decompilation Service

Professional firmware decompilation based on MCU reverse‑engineering. We convert raw assembly code extracted from microcontrollers into human‑readable, editable high‑level source code for debugging, modification and technical analysis.

About Firmware Decompilation Service

Firmware decompilation is a follow‑up technical service after successful microcontroller reverse engineering. When we complete MCU reverse engineering work, we can dump the binary firmware inside the chip and disassemble it into pure assembly instructions. Raw assembly code is difficult for most engineers to read, modify or reuse directly. Our decompilation service translates these low‑level assembly instructions back into structured, editable source code. The delivered source code allows customers to review firmware logic, adjust parameters, fix bugs, port functions and carry out secondary development. This service is widely used for legacy hardware maintenance, discontinued equipment repair, hardware security audit and embedded technical research.

What Our Service Includes

  • Raw firmware binary extraction from target MCU
  • Full disassembly to generate complete assembly code
  • Decompile assembly code into readable C‑style source code
  • Label key functions, interrupt handlers and memory addresses
  • Deliver editable source files ready for customer review
  • Basic notes for critical firmware modules

Important Service Notes

  • Decompiled source code will not be 100% identical to original developer source code
  • Some library routines and optimized code may keep partial assembly fragments
  • We provide decompiled output; customer is responsible for compiling and functional verification
  • Complex obfuscated firmware will increase decompilation difficulty and turnaround time
  • Customer shall confirm legal authorization for target microcontroller before project start

Our Standard Workflow

01

MCU Reverse Engineering

Unlock and read firmware binary data from the target micro‑controller chip.

02

Assembly Disassembly

Convert binary firmware into full assembly instruction set for analysis.

03

Firmware Decompilation

Process assembly code and reconstruct editable high‑level source code files.

04

Project Delivery

Hand over source code package; customer performs compilation and function validation.

Frequently Asked Questions

Can decompiled source code compile directly?

In most cases partial manual adjustment is required. Decompiled code restores logic, but compiler headers, chip peripheral configurations may need customer engineering tuning.

What chip types do you support for decompilation?

We support most mainstream 8‑bit and 32‑bit microcontrollers after successful reverse engineering, including STM series, GD, Atmel and other common embedded MCUs.

What deliverables will I receive?

You will get firmware binary file, full assembly listing, decompiled editable source code and necessary comment notes.
