@davidm71 - Yes, those are SPI Pins, use with CH341A but you connect the programmer via SPI Cables (or PCB adapter) instead of SOIC8 cable over BIOS chip. SPI Cable is attached like you see in this image - using this method and CH341A you need to use the serial drivers instead of parallel and you need to move the jumper on the side to 2-3 instead of 1-2
CPU pads being covered, or connected, are for Coffee Mod on Sky/Kaby boards (Or possibly other similar mods), nothing to do with BIOS recovery.
You can USB Flashback your board, before trying to do anything with programmer, have you done this yet? CPU is not required for that.
As I mentioned in another thread was able to directly connect those pins to my FlashcatUSB programmer using pitch wires with complete success. Thank you for the diagram. Saved it to my dropbox. Thank you.
There was some talk on that forum about the CH341A being powered by 5 volts and that could be a problem for flashing your roms if the wrong voltage is fed to the chip. So some folks have had to mod their device to force 3.3 v though I never noticed any issues.
hello I have a elitebook 820 g3 but I donāt have the bios password the chip is a wson, I need to soldering wire for modify the bios but I think I risk to brick my pc if I flash a custom bios Is it a good idea ? Thanks
Hello everyone, hoping someone can help me out as I am running out of hair to pull out. I have a ch341-a āproā my z77a-g41 was bricked and im trying desperately to fix it. Iām having an issue with the 1.8v adapter atm. Everytime I set it into the programmer it just disconnects and the little power light goes dim. any idea why this is? Iāve tried several different versions and drivers and I canāt seem to find anyone with this issue. Iām hoping im asking in the right place thanks guys
OH my god iām a complete numbskull I looked up the wrong chip. SO itās 3v now my issue is it keeps saying the chip with the contents are in disagreement?
just to make sureā¦ winbond 25q64fvsig is 3v? corrrect? I feel so stupid lol
I keep getting āchip with the contents are in disagreementā could it be the chip is just bad ? itās still soldered onto the board btw. im using a clip.
I tried all of the ch341 softwares most of them gave me the same error except the 1.31 that gave me an access violation error. Ill try flashrom if I can figure out how to use it. itās odd because it lets me erase the chip but not verify it. if I try to write or verify itāll give me the disagreement error.
OH sorry I thought yous aid flashrom. well I guess if I really want to fix this mobo I should get a flashcat. Or maybe just get a brand new mobo. THis is frustrating that I donāt know what exactly the issue is. it just flat out doesnāt want to work. Thanks for all your help. Iāll update if I manage to get it working.
