840 G3 Bios request

[slaine]

Hi All,

in the process of trying to remove the Bios-PW from an 840G3 I somehow F´d up and got a bad Dump. Leaving me with a broken state (power led just flickering or reboot loop with high fan speed and reboot).
I already tried differnt dumps found in this forum, no luck.

It looks like those are for the 6050xxx type Mainboard. Mine is a 6070B0883301-A02. If anyone got a clean Main-BIOS dump (16MB) and maybe the EC dump (~8MB) i would be very thankfull if someone could upload it for me to test.

Sorry, the dump is only FF´ed trough the whole area, i think I blew the eeprom while inserting it into the reader (never change the prom while still connected to usb... )
So I would need a complete cleanME unlocked dump for this machine - MB reads 6070bxxxxxx instead of the 6050xxxx type.. any help appreciated (I cannot even get the prom to read anymore, i ordered a empty one already)

the bios chip must be removed from the motherboard before reading or writing, or soldered wires between the chip and the programmer, after which we post the bios here...

Sorry, I couldn't find another way to post the dump. Unfortunately, RCUnlocker doesn't know such a BIOS and Unloker doesn't solve the problem either. Can anyone help?

I have added the file to your post. Your file is 16385KB ,it should be 16384KB ,i suspect that`s why the patcher didn`t work. I think you chose an OTP chip instead of the non OTP ,and that`s why the extra code was added.

I didn't quite understand, I throw the firmware into the exe file RCUnlocker_v_1_0 and get an error message. Firmware size 16.0 MB (16,777,984 bytes)
