    HP ZBook Firefly G8 ICSP Winbond W25Q256JVEN read out problem

    Hello i have a problem. i will try to read the Winbond memory (W25Q256JVEN) without unsoldering the chip. I use REVELPROG-IS and ther software REVELPROG-IS V1.9.1 but i have an error message.
    I have disconected the main battery and CR2032 cell battery. By default when i select the chip partnumber the voltage is 3V and i have this error message, but i will try with 2.6V that work but CRC32 checksum is different everytime.

    Anyone can help, me please ?

    Thank you
