Hello everyone,
I'm having a hard time dumping the BIOS of a Lenovo Ideapad Duet 3 (11IAN8). The chip is a Winbond W25R256JVEN, directly soldered to the board in a WSON8 package.
Since there are lots of tiny components near the chip, I was hesitant to desolder it using hot air. Instead, I soldered thin wires directly to the chip's pads and connected them to a CH341A programmer (photos attached).
The chip is detected correctly in both NeoProgrammer and ASProgrammer, but I'm unable to get a consistent dump. I've tried over 15 times — shortened the wires to...
3 results in 0.0028 seconds.

Everyone is buying the wrong CH341 programmer
Everyone is buying the wrong CH341A programmer, I have learned from my mistake. Don't buy the Black one or Green one.
Buy this one in the photo. Most stable and all your common problems (reading but not writing/erasing, software hanging, disconnects after attaching chip, test cable connected but chip not found/ device disconnected) will be gone.
Otherwise you'll have to solder capacitor from GND to VCC if you have those symptoms in your black or green miniprogrammer.... -
HP ProDesk 400 G6 mini - BIOS Password attempt to remove it
Hi,
as noobie to this please excuse my lack of experience.
I am trying to remove a BIOS password from this machine:
HP ProDesk 400 G6 Mini
but so far I still have no success.
I bought CH341 programmer and decided to give it a try.
The programmer came with 8 pin cables and connectors or whatever everything else is called so I had to buy a new 16 pin cable because the chip which I think is the BIOS is with 16 pins..
I connected everything and downloaded AsProgrammer and NeoProgrammer then installed drivers...
