I was hopeful but this didn't work for me. The modified program just keeps crashing after pressing 1. I'm using 190812 and used Free Hex Editor NEO to modify it.

Have you also tried my linked modified version? You can diff compare with stock binary if not trusting it.

Thanks. I overlooked that link. Your version worked.

Hello all. So I have followed through the guides on converting these chinese clone stlinks to a jlink. I have no luck. After the jlink firmware is flashed my stlink will just flash a red light over and over and over. I have brought it back to life using a second stlink clone but every time I get the flashing red light. I have followed this guide https://github.com/Zelmoghazy/st-link-v2-clone?tab=readme-ov-file and tried all of the tricks he states. Is there something I could be missing? Does there happen to be a bin file of the firmware somewhere so we can just flash the chip directly with a second stlink? Thanks in advance for any replies.

Yeah honestly if we can just directly flash the ST-Link firmware, why are we fucking about with a janky old utility that doesn't work half the time? Someone should just extract the binary from STLinkReflash or dump it from a clone ST-Link after flashing it with the utility.

Someone did write a decrypter (https://github.com/lujji/st-decrypt), that may be worth looking at, although it is a bit old. Sorry I have mostly work on AVR, RP2040 and ESP32 series due to their open toolchains and programmers.

Has anyone located an updater for a version older than V2.J36.S2? I'd like to try V2.J16.S4, but don't have another ST-Link to flash the bin directly at the moment. If anyone knows of a way to get onto that low of a firmware without an external programmer, please share!

Hi could anyone provide the hex file dump of the final jlink firmware? I don't have access to windows pc and cannot run the STLinkReflash.exe.
