. If the chip is recognized, you’ll see its manufacturer and ID. Backup (Crucial) : Always click

the current data twice. Compare the file hashes to ensure you have a perfect copy of the original. Unprotect & Erase : Many chips are write-protected. Click Blank Check Blank Check tool to ensure the chip is truly empty before writing. : Open your new BIOS file and click . The software will write the data and then it to confirm the flash was successful. Safety and Requirements

Because BIOS flashing involves low-level hardware interaction, it is recommended to use AsProgrammer on a stable Windows environment. For those on Linux, is the standard alternative.

Always ensure your hardware programmer matches the voltage of your chip (many BIOS chips are 1.8V and require a voltage adapter) to avoid permanent hardware damage. or choosing the right voltage adapter Releases · nofeletru/UsbAsp-flash - GitHub

It looks like you’re looking for ASProgrammer (version from around 2021, possibly build 21013) — a popular GUI for flashing SPI flash chips with CH341A-based programmers.

Here’s a direct, safe way to get that specific version:

Method 3: Internet Archive (Wayback Machine)

If GitHub and forums fail, the Internet Archive is your friend.

Navigate to web.archive.org
Search for the original GitHub release page from October 2021.
Even if the GitHub page is dead, the archive may have captured the binary file.

Method 2: Trusted Third-Party Repositories (Tech Forums)

The most reliable off-GitHub source is Badcaps.net forums and EEVblog forums.

Search for: "ASProgrammer 21013" Badcaps
Reputable users archive these builds in forum threads dedicated to "CH341A programming."
Look for attachments in the first 2-3 pages of results. These are scanned by forum admins.

Part 5: Troubleshooting Common Issues with Version 21013

Even a stable build like 21013 can fail. Here are the top fixes:

| Problem | Solution (Specific to v21013) | | :--- | :--- | | "Cannot find device" | The driver was installed incorrectly. Use Zadig to force install libusb-win32 (not WinUSB). | | Verify fails at 50% | Your chip is likely a 3.3V logic chip, but the CH341A runs at 5V. You need a level shifter. Version 21013 is sensitive to voltage droop. | | Program hangs at 100% | Close the software, unplug the programmer, plug it back in, and re-launch. This is a known USB buffer bug in 21013. | | Chip not in list | Version 21013 has ~400 chips. For a missing chip, upgrade to NeoProgrammer (a fork), but note that may cause other issues. | | False antivirus alert | Version 21013 rarely triggers alerts, but if it does, add the folder to your AV exclusions. The file is safe; older Delphi compilers sometimes mimic virus behavior. |

Part 3: Safe Download Sources for ASProgrammer 21013 (2021)

WARNING: The internet is filled with "download sites" that host old software wrapped in fake setup.exe files. NEVER download ASProgrammer from a generic "driver download" site. Always seek source-adjacent repositories.

Here is the safe way to obtain version 21013:

Conclusion: Is 21013 Still the Gold Standard?

The search for "asprogrammer 21013 2021 download" persists because hardware reliability is rarely found in the "latest and greatest" software. For technicians running legacy Windows systems or working with older CH341A clones (which are incredibly common), version 21013 represents a peak of stability before the codebase grew complicated.

While finding the raw file may take 15 minutes of searching on GitHub tags or Badcaps, the effort is worth it. You will be rewarded with a portable, lightweight, no-nonsense SPI flasher that has probably already unbricked more routers and motherboards than any commercial tool on the market.

Final recommendation: Try the GitHub release history first. If that fails, use the Internet Archive. And if all else fails, download NeoProgrammer v2.2.0.7 – it will read the old 21013 config files and give you a near-identical experience.

How to install / use

Download the .7z or .zip archive.
Extract to a folder (e.g., C:\ASProgrammer).
Run ASProgrammer.exe (no installation needed).
If CH341A driver isn’t installed, you may need CH341A driver (included in the archive or downloadable separately).
