Re: hp 450 g7
You have done excellent job. Again many many thanks for your effort. Now there is no more "Power-On Authentication". Every function running perfectly.
Both Main and Backup BIOS had been re-written as your instruction. I did one more thing, made a BIOS backup on pen-drive from HP's site. Also plug-in at the same time for extra caution.
So HP Probook 450 G7 need to rewrite both BIOS to remove "Power-On Authentication".
Appreciating your effort.
Thank you Brother.
Kind Regards

Re: hp 450 g7
Hello!
You can give DMMP BIOS (HP ProBook 450 G7 BIOS S71 dump).
On the first and on the second BIOS.
Thanks!Leave a comment:

Re: hp 450 g7
Both two files 450-G7-Locked-2021-09-11-01 NEW, and 450-G7-BackupBiosLocked-2021-09-12-03 NEW must be written to the corresponding chips simultaneously and then unlocking procedure will be OK. You're trying to flash only one chip at a time and then to test, but it won't work that way.Last edited by Vesko356; 09-14-2021, 03:46 AM.Leave a comment:

Re: hp 450 g7
Hello!
You can delete data from BIOS: Serial Number, SKU Number, Universally Unique Identifier (UUID), System Board CT Number, MAC Address 1, Asset Tracking Number.
In Hex Editor Neo errors issues.

Vesko356,
This file taken from Backup BIOS chip.
450-G7-BackupBiosLocked-2021-09-12-03 NEW.zip
That's why the user information can be read.
D.E.S.K.T.O.P.-.9.4.5.4.V.H.Q.....................................................................................................................m.s.s.q.l.s.e.r.v.e.r.0.5...........................S.-.1.-.5.-.2.1.-.2.2.3.0.0.5.3.3.8.2.-.2.9.2.6.6.5.7.5.8.2.-.1.8.0.1.2.0.6.4.3.3.-.1.0.1.0
Though you had already removed from "450-G7-BackupBiosLocked-2021-09-12-03 NEW.zip" file.
Writing this file may not work.
What do you suggest?Leave a comment:

Hey guys,
have a laptop here that has a supervisor Password (dump in Attachements).
Before i write the Serial NR.etc i wanted to say that strangely after flashing with 3 different Bios dumps and one from lenovos site
the laptop works but everytime it wants me to type a supervisor password i never set.
I thought the supervisor password is stuck in the ec bios but no it isn't either because after replacing the ec chip from one of another board it still has the supervisor password.
Anyway i wanted to ask what of the two chips is the ec bios because on the left... -
Hi friends., I am working on MacBook Pro A2159 touchbar 2019. The old logic board was liquid spilled so I ordered another logic board from AE. Received it & all worked fine till I got to the Chinese login screen where the login screen password tobe entered. I tried to reset the password but it again gave me options which I do not know about the Apple ID. I formatted the onboard SSD. & wanted to change the startup boot sequence but in order to change it, again the password is needed for that too. Is there a way to get rid of this password??

Hi all, I'm new here, a few words about myself: CS student, interested in hardware stuff too - tinkering my whole life but with practically no experience when it comes to firmware "hacking".
So I have this X380 Yoga with a supervisor password in place and before doing anything stupid I figured I'd rather ask.
I plan on using the tool from this thread: https://www.badcaps.net/forum/troubl...password-remov... -
Hello,
I'm hoping someone can assist me.
I have an Asus Vivobook 16x Pro OLED laptop which has a BIOS password, and I can't seem to find it.
It still boots into Windows (boots from whatever SSD is installed but not from USB).
The model number is M7600R and serial number is N8N0CX03H71131C.
I tried AMITSESetup Decryptor but the password I got doesn't make sense (it's got a line break and special characters).
I also tried to use *************** MOD EDIT ,redacted************** and it also gave me the funny password of

Here is all the info you should need to remove bios password from your same model or one with an MEC-Chip and also write back the config data
T14s - MEC-1663 - Jtag - Pinout - Bios Password Removal
See Diagram for Wiring.
Use MEC-1633#ISP on your RT809h
This is same Jtag pinout and method for T490S/X390
(But your R/W 10K Resistor Location May In a Different Location)
MEC-Chips Store Bios Password In a Secure Un-Editable Area
Following steps clear that secure area to re-initialize itself to default (Blank)
