Bios dell latitude 5450 intel ultra 5 135u need build

[lapfix]

Advice for the person that have RT809F

when you read a chip that isn`t supported choose a different chip with 512 capacity
use W25Q512NW that support 1.8v ...no 1.8V adapter is needed ....ignore check-ID

Thank you SMDFlea for your help

Backup fault.

Any solution to this fellas?
It's a 25LR512MEYIG and that's the Vcc Pin I guess
I just wanna be able to read the chip to post here along with ST and the other info

[ymifdal]

I guess I'ma just try to decap the chip tomorrow and look for the internal VCC pad lol
I’ve done this before on other damaged chips that come damaged but never did a WSON8

I has the same issue with the same chip. i think they purposely build it this way so no one can work on it.
I has to buy new chip to make it work

Yes they're making it kinda hard to remove by placing the ic in some tough places
I did order another IC too I'll just try to build a new bios by then since I can no longer read the old chip

It`s only read 64KB .I don`t have a SVOD programmer so i can`t advise what the settings should be.Do you have a CH341A or another programmer to make the backup with
