    Hi, I have an Elite Dragonfly G1 with 32MB Winbond Chip and boot password.
    If I use RCUnlocker it prompts: "Wrong Chip. Try reading and unlocking 16MB chip"
    Could you please help? Thank you in advance.

    Thank you for your feedback.

    I have made the changes starting from address 37000. However, it appears that it is somehow being written back from a RAM. Presumably, this is because I did not disconnect the CMOS battery. I left it installed because I'm concerned it might erase the TPM.

    You need to modify EC bios, not main bios. Address 37000.

    hello guys.

    i have some problems with
    model: 640 G8 with 32MB ROM

    i have tried to overwrite the specified sectors. after each boot it resets the chip to the original value.... Is there another version of RCUnlocker for 32MB or how can I find the right sectors?

    thanks for your help!

    Come on guys! What wrong with you? It's simply to find on youtube how to use this utility! Put your bios dump to folder with rcunlocker.exe and than just drag your bin file to the program shortcut

    Re: RCUnlocker

    Btw, I highly recommend the very simple wire-less SOIC clips that go for $2 on eBay from China.

    One can simply attached wires to the clip, and the other ends to Raspberry Pi. I had 20cm wires. To create some room for wires to be attached, I bent clip's pins into the middle and out in a staggered way.

    I saw some pictures out there where the clip wires go to a break out board first, and then have to get connected to Raspberry. That's an extra step, and tons of possible confusion.

    See pictures.

    Unlocked 8470p, all good! Great tool!

    Replaced CMOS battery while at at - why does HP wrap it into plastic ... Slightly shorted a good 2032 Duracell while attaching wires.

    The program gives an error at the end, but that does not seem to impact anything, and the unlocked bios is produced OK.

    Re: RCUnlocker

    By soldering wires, it might work

    Re: RCUnlocker

    So there's basically no way without removing it?
