    Default Carprog not Recognized after Repair Procedure

    Hi,

    My attempt to repair carprog 9.31 didn't go well.
    I desoldered eprom AT88SC and lifted PIN 55, solder pin 55 to VDD, connected to pc wait about 20 seconds, disconnected from pc, soldered pin 55 to GROUND.
    Now carprog is not recognized by pc when connect via usb, the green light is tuned on though.

    Any help will be appreciated.
    Thanks in advanced!

    I forgot to mention that the Jflash program does not recognize the device.

    Not need connect to GND, not need desolder AT88, I always connect to 3.3v, then connect +12v (about 10sek), next step disconnect +12v and connect to programmer, if programmer connect with ARM I disconect 55 leg from 3.3v, if not I connect +12 to carprog and after this programmer see ARM, then desconnect 55 leg from 3.3v and program ARM

    After flashing my 55 leg is always in up and not connected.

    Thanks for the support, It worked!
    I installed J-link sw on an old pc with Windows XP then the program detected MCU and programmed. I did like you told me: just let pin55 up until the end of programming and soldered to GND.
    All the best!
