Update Ktag Clone From 225 To 270 [updated] May 2026

The STM32F205 chip can be unbricked by desoldering it and using a universal programmer (Raspberry Pi Pico with OpenOCD). But at that cost, buy a new clone. Conclusion The journey to update your KTAG clone from version 2.25 to 2.70 is a technical minefield, but it’s doable with the right hardware (STM32F205), a stable 12V supply, and a reliable bootloader file from trusted forums. Always back up your original firmware before starting, and never attempt this update on a Friday afternoon before a customer job.

Congratulations – you now have a 2.70 clone that performs 95% like an original. Backup your working firmware immediately using a ST-Link V2. update ktag clone from 225 to 270
