Hey Guys

I just bought my First Notebook with a Bios ADMIN lock

NOTEBOOK: Dell Latitude 5300 Gen 8
MOTHERBOARD: NorthBay Non-TBT MB A00 18827-1 P3HJY$JA

i found 3 BIOS chips on my Motherboard

1.) MXIC MX 25L3006E M2I-12G => chip sits on the front of the MB, next to the HDMI Port

2.) winbond 25Q128JVSQ 1941 => chip sits on the front of the MB, next to the FAN-Connector

3.) winbond 25Q64JVIQ 1942 => chip sits on the backside of the MB, next to the Fan


So sadly i have no Tools for reading out the Bios chip, but thats why i ask here to get the correct and hopefull not too expansive tool to read and write the chip

So, can somebody tell me which of these 3 chips are the correct one i have to read and write, and which tool you recommend

Thanks Guys

Look

hey, thanks for your answer, so you pointed to chip 2 and 3, why 2 chips, are there the same bios on it or what

would love to do this with chip nr. 2 because this i should be able to read out without desoldering (because of the legs of the chip)

Your bios file is divided into 2 parts. 8 MB and 16 MB.

I'm sorry, I don't have the device itself, they just asked me to help and gave me the dump itself. I have already successfully removed the password using a hex editor. Sorry for disturbing.

If you want to unlock the bios, you can reluctantly use the 8MB file (but it's best to have enough bios_8MB + 16MB files, it helps people unlock faster).

yeah but the problem is that the WSON8 chip will be much harder to read out and write because of the WSON8 form factor, iam new to this bios soldering things, so i would prefer if anyhow possible to use the

chip winbond 25Q128JVSQ 1941 for doing this

today i should get my order CH341A with the clamp, but this set wont work easyly on the WSON8 winbond 25Q64JVIQ 1942

but would be easy i guess to do on the winbond 25Q128JVSQ 1941 chip because the clamp would work here


so thats the reason for asking this

thanks

do not use clamp or any stupid wires, just remove the chip directly and put in adapter.

hey guys i did it it worked with my CH341A

i desoldered the CHIP on the BACK and also read out the Chip on the Front via Clip (worked perfectly)


My Service Tag is

F2TBJW2



Would be mega nice if someone could sent me the file of the new BIOS which i have to write back to the CHIP.


I am so proud of me haha that i managed to desolder this and read out everything like you guys need from me (i hope so ;-).


Yeahhh

the program is good.. the question is does the backup or dump is good? additional ch341a does not read properly sometimes better u get rt809f or svod for better reading

1.) maybe i did something wrong while soldering
2.) maybe the unlocked bios is not correct

@hoaca388

can you also look into this, i am new to this and soldering this chip on and off many times doesnt make it better i guess

maybe anyhow possible to read out the adminpassword via the bios file?
