Re: HP BIOS unlock tool
Hello all,
sorry to bother you again.
Yesterday I tried it again:
- soldered the original chip back: laptop worked, I could boot W10 from the SSD
- desoltered again and connected again to CH341A I could finally read out the content without any problems, so now I have a dump
- created an unlocked bin file, programmed it to the new chip and soldered onto the mainboard: same problem, the LEDs of the caps lock and num lk buttons blink several times, the fan goes on, then the laptop "restarts" again and again. I tried holding several buttons on power on, no luck.
- unfortunately I managed to break off a pin of the original chip, so cannot try to reprogram it anymore
- the new chip has the IDs:
ID(9F): EF7018, ID(90): EF17, ID(AB): 17, ID(15): 6060, the original one ID(9F): EF4018, ID(90): EF17, ID(AB): 17, ID(15): 6060 but both were recognized by CH341A Programmer as Winbond W25Q128FV. Could that be the problem?
Could you please check, whether my dump and the unlocked file looks OK for you?
