Once installed correctly, the device will appear under or USB devices in your Windows Device Manager, rather than under COM ports. Step-by-Step Guide: Flashing with NeoProgrammer 2.1.0.19

Review the hex data in the main window to ensure it isn't just a screen full of FF FF FF or 00 00 00 (which indicates a bad read). Click and name it original_backup.bin . 4. Write New Firmware

NeoProgrammer虽然强大，但也要保证数据库足够新。尤其在刷写或新型NAND-SPI闪存时，官方旧库可能没有对应。

The CH341A was an enigma. It was a cheap, mass-produced programmer based on a Winchiphead USB interface chip. For $5, it could speak I²C, SPI, and MicroWire. In theory, it could read and write BIOS chips, EEPROMs, and 24-series flash memory. In practice, the factory software that came on the mini-CD with it was a crime against usability. It crashed on Windows 10, misidentified chips, and hadn’t been updated since 2014.

No installation is required. Simply unzip and run the executable. Built-in Hex Editor:
