Files for flashing ST-Link V2 clones with J-Link firmware:
STLinkReflash_for_clones_patched.exe- Modified version of SEGGER STLinkReflash utility. Patched to skip hardware and firmware checks, assumes ST-Link V2.jlink_firmware.bin- J-Link firmware for manual flashing (ST-Link V2 only). Can be flashed with stlink-toolstlink_restore_firmware.bin- Restore firmware. Not sure what it does, you'll likely need to use the STLinkUpgrade tool to complete the restore process anyway.
Manual flash and restore example (use this stlink-tool fork for bootloader restore switch):
$ ./stlink-tool/stlink-tool jlink_firmware.bin
