Hello everyone,
I'm having a hard time dumping the BIOS of a [B]Lenovo Ideapad Duet 3 (11IAN8)[/B]. The chip is a [B]Winbond W25R256JVEN[/B], directly soldered to the board in a [B]WSON8 package[/B].
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 [B]CH341A programmer[/B] (photos attached).
The chip is detected correctly in both [B]NeoProgrammer[/B] and [B]ASProgrammer[/B], but I'm unable to get a consistent dump. I've tried...
3 results in 0.0016 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:
[B]HP ProDesk 400 G6 Mini [/B]
but so far I still have no success.
I bought [B]CH341 programmer[/B] and decided to give it a try.
The programmer came with [B]8 pin [/B]cables and connectors or whatever everything else is called so I had to buy a new [B]16 pin cable[/B] because the chip which I think is the BIOS is with [B]16 pins[/B]..
