Hi There, I have incorreclty flashed the wrong bios on a MX25L25673G chip from my CWWK Q670-4L motherboard. USB ports are no longer working after the incorrect flash and I’m trying to flash the correct bios with a CH341a programmer and AsProgrammer.
I think I have been able to wipe the bios as it currently read only FF values.
But trying to flash the new file As Programmer says "Possible protection is enabled. Press “Unprotect” and check datasheet.
I have tried to “unprotect” but the program just sits there withou progress bar for over 30 minutes. Same for trying to flash the bin file is just runs without any result.
Any idea what I’m doing wrong, I have reached out to CWWK but so far they have been limited in their replies.
FF is ZERO DATA, does any app auto identify the IC, besides ASprog, then its bad grip to it.
How many times have you used a CH341A or any other programmer?
Other apps like NeoProgrammer and Colibri, etc… can be used.
None of the applications auto detect the chip, AS programmer lets me read the chip if I manually select it. NeoProgrammer says IC not responding.
This is my first time using the CH341A, do you think the clamp is not corretly connected ?
I have the 24 + 8 pin connected to the motherboard otherwise the CH341 isnt detected. Removed all other connections from the motherboard only left the CPU installed.
What i suspected… so its bad conection/grip to the IC and not easily achieved by an unexpereinced user.
Who told you to use PSU stand by on that mb model??? The IC model only needs 3.6v max. The CH341A gets enough power from the USB port, wrong use of the programmer makes also programmer/app not being able to comunicate and can damage components.
Else its the mb IC access circuit design thats blocks the signal, in such cases the SPI IC must be de-soldered from the mb to be programmed outside.
So the CH341a is recognised by Windows up till the point I connect the clamp. So I figured the USB port didnt provide enough power for the MB 3.3v rail.
Im going of YouTube videos with this to be honest, and about to give up on this mainboard.
