Hello, friends, I hope you can help me..... I have a Dell Latitude 5330 that without realizing it and because of those things in life I did something wrong, I deleted the data from the 25Q80 Chip (8MB) the other 16mb and 32mb chips do have them but the notebook is totally dead and has not done anything since Delete those files, I hope you understand me and can help me, thank you friends.

Hello BIOS gurus,

I have DELL Latitude 5330 (S/T:12CYXL3, motherboard model: Southpeak 4DJ9K$LA 203101-1)) and would like to unlock the BIOS admin and remove any trackers e.g. Absolute or CompuTrace.

I have taken the backup of W25Q256JV chip using CH341A programmer. Please see attached the bin file. Could someone help unlocking this attached file.

Thanks,

PS: I am hoping that this is the chip that contains the BIOS? because there is another chip W25R128JV that sits close to this chip but I am not sure if that needs to be re-flashed?

Thank you friend for your prompt response. I flashed that file but unfortunately the laptop doesn't start, when I press the power button, the white Power light comes on the button for 30 seconds and goes off. There is no display, no fan, no keyboard light, nothing happening on the laptop. I did the following:

(1) Prior to flashing the file, I removed the battery and CMOS battery connections both.
(2) Flashed the file and verified that the file was correctly verified.
(3) Connected the CMOS battery, and pressed the power button for about 30 seconds prior to connecting the laptop battery.
(4) Pressed the Power button after connecting the laptop battery.
(5) White light on power button comes on for about 30 seconds and goes off.


Any ideas? Are there any chances that the file that I read originally might be corrupted and therefore the unlocked file is also corrupted? Or the unlocked file is just a generic one?

Anyone? Please help 🙏

Anyone? Please help 🙏

check soldering. Put back original bios and see if it starts, if not, you didn't read properly bios chipset.

[robin.office]

Ok I will try flashing the original BIOS file and see if that works. In case it doesn't, do we have a generic BIOS file for this model?

I didn't desolder the chip, I used WSON8 pogo pin probe to read and write it.

Thanks.

I flashed the original backup file and the laptop doesn't start, so I am convinced that my backup file was corrupted. Can anyone help with repairing the file? Or is there a universal BIOS bin file that I can flash? What options do I have, if any
