Hi pros here, I really need your help to start but just look like so dumb... My 5440 with LA-M401P has a chip 25R128JVSN. However I tried to run AsProgrammer1.4.1, CH341-main, and NeoProgrammerv2.2.0.10 but none of them have this chip. I then clicked "Read ID" or "Detect" try to find the chip but all just stuck there. I randomly chose an IC model and tried to read IC directly and the programmers are stuck too.

I then disconnected the cmos battery and chose W25Q256FV from AsProgrammer since its size is 33554432 which matches 25R128JVSN. I then clicked Read IC and surprising it can read in seconds. However it tells me "Number of bytes readed not equal IC size" error. I can save the reading to a 32MB sized file. But it only goes to ~20k when I compress it to zip file. Apparently it's not right since I see all the zipped bin files here are ~8MB.

Anything I did wrong or missed? How did you guys read this chip without support from the software? Your help is so appreciated!

The W25Q256FV is 32MB , the 25R128JVSN is 16MB

[durianmustbeback]

The W25Q256FV is 32MB , the 25R128JVSN is 16MB

Thank you! But what chip should I use instead since 25R128JVSN is not listed in AsProgrammer?

[SMDFlea]

Winbond 25Q128JV

[durianmustbeback]

The W25Q256FV is 32MB , the 25R128JVSN is 16MB

I can read now but can only read all 0. Saved and compressed to zip it's only 20kb. What did I do wrong? Thank you

are you using clamps? It's not reliable, especially with CH341, desolder chipset and read it using SOIC_DIP adapter or solder it on the board came with Ch341

I see. Will desolder it and try. Thanks a lot!
