Help a noob! Wson8 Pogo/Needle Adapters to read/Write

[Doesronnieevenlift]

Hi all,

I had recently tried to reflash the bios on a dell latittude that has a Wson8 Chip however to no avail.

My question is, Has anyone had much success using the Pogo/Needle adapters to read and write bios without removing the chip from the main board?

I seem to struggling with the solder process wofh my reflow station and currently have 4 machines waiting for a bios mod/reflash.

For context I have just ordered a EZP2019 SPI flash so this is what I would be using alongside the Pogo Adapter.

Apologies if this is the wrong subcategory. I'm a new member to badcaps however have spent a long time reading through the website.

Thanks in advance!

if the board has a programming header like some MSI boards then it can work,
but usually you have to lift the chip because of other parts connected to it that mess with the programming.

Thankyou for your response. Iv got a donor motherboard so I might have to try and test my solder skills with my reflow station 🤣 Practice makes perfect!

I do use pogos for wson8 in some cases. But never to read out or write the whole chip. I just read out a certain small section, automatically modify it and write back, so it takes just seconds. And even in that case, it's kinda unstable.
So for most cases, soldering is the way to go. It is not hard. Correct temperature and never apply any force on tweezers. Atleast that's what beginners tend to do wrong. It should come off easy.

Thankyou for your reply!

I had previously tried to desolder a chip and replace it with a preprogrammed one however to no avail. It was a 11th Gen Dell Latittude, However up-on installing the new chip the machine wouldn't boot. I do have 3 more laptops too attempt however moving forward I'm going to try and modify the current bin file as opposed to replacing the whole chip. Could I ask, When replacing the bios chip with a pre-programmed one, Should I have replaced the EC chip? I'm truing to workout where I went wrong. I did resolve the original chip back however the laptop still wouldn't boot 😑

Thankyou for taking the time to reply! Your knowledge is highly appreciated.
