You need to open the plastic case. Yes, void that warranty sticker – it’s a clone anyway.

Updating to 2.70 is the best "free" upgrade you can give your shop, provided you respect the offline rules and use a quality SD card.
Updating a KTAG clone from version 2.25 to 2.70 is primarily a protocol update that expands vehicle support while maintaining 2.25 as the reliable "working" interface for reading and writing.
Instead, the process uses KSuite 2.70 to flash a new set of communication protocols onto your KTAG clone's hardware (often the 7.020 PCB). After this, KSuite 2.25 will support the newer ECUs.
If you are a professional tuner or mechanic seeing 2017+ models in your shop, you need to be on v2.70. The update is stable, but treat the process with respect. If you are a hobbyist only working on older cars (pre-2015), you probably don't need to risk fixing what isn't broken.
The move from to 2.70/2.80 provides several advantages:
The buffer fills. The checksums match. The clone reads the bootloader.
Usually, "Red PCB" or "EU Clone" versions are the safest to update. Green PCBs can be updated, but they often require a higher quality SD card to avoid "Connection Error" messages.
Clone micro-SD cards are notoriously unstable. Replace the stock SD card with a high-quality 4GB Class 10 card formatted to FAT32 before starting. 💾 Step 2: Download the Required Update Files
