Clones often use recycled or counterfeit FPGAs. The "2.25" label on your software is just a GUI version. The real firmware is stored in the STM32 and FPGA.
If you need help resolving a specific error code during this process, please tell me the you see on your screen. Alternatively, let me know the PCB color of your Ktag board so we can determine if any hardware transistor modifications are required for your specific clone version.

You are likely still running . The official world has moved on to v2.70+. The good news? You can update. The bad news? If you do it wrong, you will turn your $200 tool into a paperweight. If you need help resolving a specific error
Older green boards often feature lower-grade components and an older firmware chip. Attempting to run KSuite 2.70 on a standard Green PCB without manually replacing the NXP chip or rewriting the LPC2478 microcontroller firmware with a J-Link programmer will result in grayed-out protocols or a locked device.
