This is the first time I try to use an USB CH341A USB miniprogrammer to try to recover a laptop totally bricked by an error during the BIOS update and I'm not sure if I have connected everything properly.

The chip that I need to flash is this Asus laptop motherboard BIOS


And this is my USB programming device



Clearly the pin number of the clip out should mach the order with the chip pins, but my first great doubt is about the connection of the clip cable and jumpers to the USB programmer. In this video you can see how I have tried to connect the clip cable to the USB programming device.

@AndreaF red like = 1 = pin next to the dot on your chip (bottom right in your case). follow this guide if you have any other issues: [GUIDE] The Beginners Guide to Using a CH341A SPI Programmer/Flasher (With Pictures!)

@AndreaF
notice how there is a diagram below the pin block that says 25xx - your #1 pin should be in the same place as the white dot in the top right corner.

@AndreaF

the second pic is the right one. make sure you're only putting the connector in the holes for 25xx

@AndreaF - Pin one on the programmer is in the middle of the inside block, on the lever side (Your very last image above in post #5 is correct)
Check this guide, all connections explained very nicely with images [GUIDE] Flash BIOS with CH341A programmer

Thanks to everybody. The very last image is basically what I have done initially, as shown in the video and pictures of my very first post, then thinking that I have done something wrong I have gone in confusion.
