Using a Linux machine, use evoplus_cid or similar software to change the SD card's CID to the specific ID required for 7.020, which is 035344535330344780399b1368010300 .

Do not proceed without these items:

Updating a KTAG clone from an older version like V2.25 to the newer V2.70 is a popular way to expand the ECU protocol support for tuning, particularly on vehicles utilizing Bosch EDC17 or MED17 units. As of 2026, many users still rely on these cloned tools for their cost-effectiveness. However, this process is not as simple as installing new software; it usually requires modifying the underlying firmware, often changing the SD card content and firmware version to V7.020 for compatibility.

Instead of running the .exe , Marco opened a hex editor. He compared the old with the new 2.70 file. Hidden in the new firmware, at offset 0x1F4C , was a small routine: if (checksum != 0xKTAG_AUTH) erase_all_flash();

Now the real work. The clone has an internal STM32 or ATmega chip holding the firmware. We will replace the v2.25 firmware with a patched v2.70.

Download and extract the KSuite 2.80 / FW 2.70 compressed archive to your desktop using 7-Zip or WinRAR.

The original Alientech cards have a writable CID (Card Identification). Most regular store-bought MicroSD cards do not allow you to change the CID. If you need to replace your SD card entirely, you must find an SD card that supports CID modification (often older Samsung cards or specific cards labeled "CID Change supported").

Open the extracted folder and locate the main setup file (often named KSuite2.80_Setup.exe or a pre-installed KSuite folder).
