FirstChip FC MP Tools and Antivirus: Safe Use on Windows 10/11, Exclusions, and Driver Issues

User question

Do I need to turn off all antivirus on system to use FC MP tools

Artificial Intelligence Response

Direct answer to the question

• You usually do not need to turn off all antivirus to use FC MP (FirstChip Mass-Production) tools. Start by adding exclusions and/or disabling only real‑time scanning for the tool and its temporary driver. If the tool still fails (e.g., cannot install its filter/port driver or loses the device mid‑flash), then temporarily disable protection while the PC is offline, complete the job, and re‑enable protection immediately.
• Key points:
  • FC MP tools perform low-level, driver‑install and firmware operations that many AV/EDR products block heuristically.
  • Prefer targeted exclusions and least‑time disabling over “turn everything off.”
  • Use a dedicated, offline bench PC when possible.

Detailed problem analysis

• Why AV/EDR interferes

  • Behavioral engines flag actions common to MP tools: unsigned or legacy kernel driver install, raw USB commands, firmware updates, and direct disk access. Ransomware/Device Control modules and “Controlled Folder Access” can also block temp files, logs, or driver staging folders.
  • Timing is critical during controller flashing; AV hooks can add latency or kill the process, risking an incomplete write and a bricked device.

• Windows security features that commonly block older MP tools

  • Driver Signature Enforcement and Memory Integrity (HVCI) reject many legacy filter drivers bundled with MP tools.
  • SmartScreen and Reputation‑based protection may quarantine executables packed or flagged as “HackTool/RiskTool.”
  • Corporate EDR (device control/USB control) can silently block exclusive access to the controller even if the EXE is excluded.

• Practical risk model

  • Data risk: the process is destructive; any interruption can render the stick non‑enumerable.
  • System risk: disabling protection raises exposure. This is mitigated by working offline, using only vendor/verified tools, and re‑enabling protection immediately.

Current information and trends

• Trend toward stricter OS hardening (Windows 10/11 HVCI, reputation-based blocking) means older FC/FirstChip tools more frequently hit driver‑signing and heuristic blocks.
• Industry practice among repair benches is to use a clean, offline workstation (often a minimal Windows 7/10 install) specifically for MP tools; AV is kept minimal or disabled only for the session, with network unplugged.

Supporting explanations and details

• Why exclusions sometimes aren’t enough
  • File-based exclusions prevent signature detections, but behavior engines/EDR still intercept kernel driver install and direct I/O. If the tool still fails after exclusions, a temporary full disable is justified—but only offline and only for the shortest window.
• Typical components to exclude
  • The MP tool’s folder and executable(s).
  • Any bundled driver folder (often “driver,” “filter,” or “sys” files next to the tool).
  • The temp working directory the tool uses (sometimes under %TEMP% or a subfolder it creates).
• OS/USB specifics
  • Use native chipset USB ports; many FirstChip tools behave more reliably on USB 2.0 ports.
  • Always run the tool “as Administrator.”

Ethical and legal aspects

• Only use MP tools obtained from legitimate sources; repacks are frequently malware‑laden.
• Respect organizational security policies; circumventing managed AV/EDR may breach policy.
• Modifying USB IDs/firmware can have compliance implications in certain environments.

Practical guidelines

• Recommended workflow (safe and reliable)

  1. Identify the controller first (e.g., with ChipGenius/FDIE) and obtain the exact matching FC MP tool version.
  2. Back up data; the process erases the device.
  3. Prepare a clean environment:
     • Prefer a dedicated, offline Windows bench PC.
     • Disconnect network (unplug Ethernet, disable Wi‑Fi).
  4. Try the least‑privilege approach:
     • Add AV exclusions for the tool folder, EXEs, and driver .sys files.
     • Turn off only real‑time scanning and behavior shields for the session.
     • Keep the Windows Firewall on.
  5. If the tool still fails to detect the drive or install its driver:
     • Temporarily disable AV/EDR fully for the shortest possible time.
     • If needed, temporarily turn off Memory Integrity (HVCI) and reboot; re‑enable after the job.
  6. Run the tool as Administrator on a native USB 2.0 port; do not interact with other apps until complete.
  7. When done, close the tool, re‑enable all protections, re‑enable HVCI if changed, reconnect network, and optionally run a quick scan.

• What not to rely on

  • Virtual machines: USB passthrough often fails for the exclusive, low‑level modes these tools require.
  • Third‑party “one‑click Defender disablers”: these are unnecessary and may themselves be flagged.

Possible disclaimers or additional notes

• Using the wrong MP tool/parameters can permanently brick the device.
• Some sticks require entering boot/ISP mode (occasionally via pads or a test key sequence); do not attempt board‑level shorts without proper instructions and ESD precautions.
• On corporate endpoints, do not disable protection without admin approval; use an isolated lab PC instead.

Suggestions for further research

• Determine your exact FirstChip controller model and target the correct MP tool release notes.
• Review community repair notes for that controller family (common parameters, known pitfalls).
• Study Windows driver‑signing/HVCI behavior if your tool bundles a legacy driver.

Brief summary

• Don’t reflexively turn off all antivirus. Start with exclusions and minimal, temporary disabling of real‑time/behavior shields. If and only if the tool still cannot install its driver or maintain a stable session, disable protection briefly while offline, complete the flash, and re‑enable immediately. For repeated work, use a dedicated, offline bench PC to avoid compromising your main system.

If you share your OS version (e.g., Windows 10/11 build), antivirus/EDR product, and the exact FC controller ID, I can give precise exclusion paths and any Windows security toggles you may need.
