The text refers to AsProgrammer 2.1.0.13_fix , a popular alternative software used for the CH341A USB programmer to flash BIOS chips, EEPROMs, and SPI Flash memory. Key Download & Resource Links Official Forum Discussion
: The most current updates and community support are typically hosted on the 4PDA forums , where version 2.1.0.13_fix is highly recommended as a stable "fixed" version. Alternative Download Source : You can find download links and brief manuals on МихаТроник (mixatronik.ru) , which hosts the 2.1.0.13_fix version specifically. Required Drivers : To use this software, you must install the (parallel/programmer mode) driver. Important Usage Tips Driver Signature
: On modern Windows versions (8, 10, or 11), you may need to disable driver signature enforcement to install the programmer drivers correctly. Voltage Warning
: Many standard CH341A programmers (the "black" version) output 5V on data lines, which can damage 3.3V BIOS chips. Ensure your programmer is hardware-modded for 3.3V or use a 1.8V adapter if necessary. Alternative Software
: If you encounter issues with AsProgrammer, community members often recommend NeoProgrammer as a robust alternative. select the correct chip within the AsProgrammer interface?

The clock on the wall of Leo’s workshop read 2:17 AM. The only light came from a gooseneck lamp clamped to a metal desk cluttered with ZIF sockets, loose EPROMs, and a tangle of jumper wires. In the center of the mess sat a salvaged BIOS chip, its legs tarnished but still serviceable.
Leo’s fingers hovered over the mouse. On screen, a browser tab was open to a dusty forum for hardware reverse engineers. The thread title read: asprogrammer 21 013 updated download. asprogrammer 21 013 updated download
He’d been using version 20.11 for three years. It was stable. It was reliable. It had never let him down. But tonight, he needed to talk to a particularly stubborn Winbond W25Q128FV that refused to play nice. The chip held the key to unlocking a boot loop on a vintage arcade board—a board that belonged to a client who was paying triple for a rush job.
The forum post was from a user named PicoFlasher_Actual. No avatar, join date: yesterday. The message was simple:
Fixed buffer overflow on page writes >64k. Added support for MX25L25673G. Compiled with newer libusb. Link expires in 24 hrs. Enjoy.
Below that, a short URL.
Leo’s professional paranoia kicked in. He scanned the comments. Three replies, all from senior members with high post counts.
Leo hesitated. He’d been burned before by “updated downloads” that turned out to be cryptominers or, worse, brickware that scrambled flash chips for fun. But the arcade board was worth $2,000. The chip was worth $0.50. He made a decision.
He clicked the link.
The download was fast—only 1.2 MB. He ran it through a sandboxed Windows VM first. No suspicious network calls. No registry tampering. The executable had a valid digital signature from a Russian developer he vaguely recognized from the EEVblog forums. The text refers to AsProgrammer 2
He copied the file to his dedicated programmer laptop, an old ThinkPad running Windows 7 with no internet access. Double-clicked. The UI flickered to life. Same Spartan layout. Same blue-grey background. But under the hood, the version string now read: ASProgrammer v21.013 (Build 2025-02-18).
Leo loaded the Winbond chip. Set the voltage to 3.3V. Selected the correct profile from the newly expanded list—and there it was: MX25L25673G (verified). Not his chip, but a good sign.
He hit Read.
The progress bar moved smoothly. No hiccups. The buffer window filled with hex data. He compared the first few lines to a known good dump from the internet. Identical. No bit rot, no glitches.
He took a breath. Then he clicked Erase.
The chip wiped clean in under two seconds—faster than the old version by half. He loaded his patched BIOS image. Hit Program.
Verification passed. 100%.
Leo leaned back. The chair creaked. He looked at the CH341a programmer, its red LED blinking contentedly. On a whim, he clicked the Info tab in the new version. A hidden field appeared at the bottom of the dialog box: For bricked routers: Uncheck "Check ID" before writing
“Some chips contain more than just code. Some contain ghosts. — PFA”
He stared at it for a moment. Then he shrugged. Ghosts or not, the arcade board would boot.
He ejected the chip, seated it carefully into the board’s socket, and powered it on. The CRT flickered. A chime sounded. Then the familiar attract mode of Galactic Ranger II filled the screen.
Leo smiled. He closed the laptop, unplugged the programmer, and reached for his coffee mug. Cold. But he didn’t care.
Tomorrow, he’d write a thank-you post in the forum.
But first, he’d make a backup of asprogrammer 21 013 onto three different drives. Some tools were too good to lose to a dead link.
Drivers subfolder.CH341A_DRIVER.exe (for Windows) as Administrator.25 series SPI flash chips (common in laptops and motherboards) compared to older 1.x versions. It handles chips like the W25Q128 and GD25Q128 much more reliably.This is the most critical section. Many third-party “driver download” sites bundle adware, miners, or outdated builds. Do not download from softonic.com, uptodown.com, or similar re-packagers.
Even with the updated download, users sometimes encounter problems. Here are solutions for the top four issues:
| Issue | Solution |
|-------|----------|
| Programmer not detected | Reinstall the CH341A driver. Try a different USB port (USB 2.0 preferred). |
| Chip not in list | Manually select a compatible chip family (e.g., MX25Lxxxx). Or use "Generic SPI" mode. |
| Verification fails after write | Reduce SPI speed in Settings → Advanced → "Read/write delay" set to 10 µs. |
| App crashes on launch | Delete the settings.ini file from the ASProgrammer folder and restart. |
