Be careful – many “programmer” tools are distributed via forums, not official stores.
Suggested safe sources:

⚠️ Always scan downloads with VirusTotal – some versions have been flagged for false positives due to direct hardware access.

The very fact that this version is hard to find suggests it may have been superseded by a breaking change – e.g., 2.2.0 might have removed CH341A support, making 2.1.0.13 a golden version for certain hardware. That makes it a kind of “lost artifact” in programmer tooling history.

If you clarify the exact tool name or origin (e.g., a screenshot, forum post, or error message), I can help pinpoint the legitimate download or an alternative.

AsProgrammer 2.1.0.13 is a popular alternative software used for the CH341A USB programmer, widely favored by enthusiasts for its support of various EEPROM and SPI Flash chips (like the 24, 25, and 93 series). It is often used for tasks like BIOS recovery, router firmware flashing, and TV repairs. Download & Setup

Download Sources: You can find the portable version of AsProgrammer 2.1.0.13 on community platforms like 4PDA or via mirrored links on Google Drive and MDCLAB.

Driver Installation: Before using the software, ensure the CH341PAR driver is installed so your computer recognizes the programmer. Guide to Using AsProgrammer

To safely flash a chip, follow this standard workflow recommended by the community:

Hardware Connection: Insert your chip into the correct slot (24 series or 25 series) or use a SOP8 clip for in-circuit programming. Ensure the orientation matches the markings on the programmer.

Unprotect: Many chips have write protection enabled by default. Use the "Unprotect" function in the software menu before attempting to erase or write.

Read & Backup (Crucial): Always click "Read" and then "Save" the current firmware as a .bin or .hex file. This acts as a recovery point if the new firmware fails. Erase: Click "Erase" to clear the existing data.

Blank Check: Run a "Blank Check" to verify the chip is truly empty. If it fails, the chip may not be seated properly or may be damaged.

Open & Write: Open your new firmware file and click "Write".

Verify: Finally, click "Verify" to ensure the data written to the chip matches the source file perfectly. Quick Troubleshooting

"Memory not null" error: This usually means the chip wasn't erased properly. Try "Unprotecting" again or check the physical connection.

Interface Language: If the software opens in another language, look for the "Language" menu (often the last or second-to-last item) to switch it to English.
