Older FTDI chips are sensitive. Use a USB 2.0 port if possible. If you only have USB 3.0 (blue) ports, it may still work, but 2.0 is preferred [6].

Without administrative privileges, the software might be blocked from opening the local COM ports required to communicate with the USB hardware. Right-click the iprog.exe executable file. Select . Go to the Compatibility tab.

The main MCU chip can lift from the board due to epoxy coating contraction. Reflowing the MCU by applying heat to re-establish solder connections has revived bricked devices.

The iProg+ software and device use indicators to signal the connection state: No Power/Damaged:

: The power regulation components on clone devices are often of poor quality. Voltages may drop under load, causing the device to disconnect when attempting to read or write. The transistors or DC-DC converters can fail.

The "Programmer not connected" status typically stems from four specific system bottlenecks:

If you're using Windows 10, try these specific solutions:

Completely disable or third-party antivirus software temporarily.

By systematically isolating the drivers, the operating system security, and the physical connection, you can reliably clear the "Not Connected" status and unlock the full capabilities of your iProg+ programmer.

Does your device show when plugged in, or is it completely dark? How to Repair iProg+ Clone Port Error?

Once the driver is installed, verify how your computer views the programmer. Keep Device Manager open and look under two specific sections:

Windows often blocks the driver needed for clone programmers. Go to . Under "Advanced startup," click Restart now .
