    Had the same problem. After buying qfp64 adapter 90% of the problems where gone. For the rest i had mcus that are damaged and could not be read.. So are you sure that your mcu is not bad ? Try to read it in circuit with carprog it can also read flash..

    Regards

    mcus 100% ok. i read eeprom and flash with omega without any problems. 1j35d was read success as 4j74y and when put quartz 12mhz at pin 58 and 59 so i think something not ok with my programmer.

    Series clone can not read as 4j74y all time.

    but it can be read as 2j47y and 3k85k at beginning with 8 "00" as ss but failed verification.

    then trying to upgrade from 2.5 firmware to 2.7 but can not pass check sum.

    then not long link as 2j74y, noe 3k85k anymore with same reset
    one need to be high issue.

    however, still can read ess mode by entering 8 "00""
