        you need to send a new dump, do it with tl866 if you have one.

                      No, I've removed the chip and read it directly
                      I even tried a virgin dump from here, but the computers turns on but nothing appears on the scren (stays black)

                        but what's your problem? bios password? if it is, you can't just take a clean dump and put it in your machine, especially if it's lenovo, it doesn't work like that.

                              believe it is not! I made a junction between what you gave me from the link with your dump.

                                You've maybe by mistake uploafed the wrong file
                                Because the 1 you've uploaded I've compared them byte by byte, and the is zero differences

                                  I took this file "DUMP FILE" and made a union with its original dump. Just do the test on the machine and then comment here what happened.

                                          Hi there,

                                          This is my first post. I just wanted to come here to get a clear answer from some people about MDM removal on the 16 inch 2019 A2141 MBP & 15 inch 2018 MBP A1990. I have seen a lot of things on MDM removal, and wanted to know exactly what is needed to remove it, and what the best option is in 2024 when running Sonoma.

                                          I know that Checkm8 have an MDM removal service now, that seems to be a permanent removal. I also have heard you can remove the T2 ROM and use a programmer to read the data and change the serial number. Im not 100 percent sure if this is a...

                                          Computer in question : Razer Blade 15 2020 Base Model

                                          What I'm trying to accomplish:
                                          I want the computer to properly boot with an external display with the attached display disconnected from the motherboard. I have a CH341A programmer and full capability of modifying the BIOS easily. I Have tried various setting changes to no Avail.

                                          What I've tried thus far: Too much to note and I really dont remember everything I changed but here it goes.

                                          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...

                                          Summary of BIOS Whitelist Removal Problem


                                          Problem:
                                          I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
                                          Initial Findings:
                                          • My current BIOS version is N1KET58W (1.45).
                                          • I have a CH341A programmer and have successfully created two full backups of my BIOS.

                                          • I attempted to use several automated and manual patching methods on my N1KET58W (1.45) BIOS, including using hex strings. These attempts all failed.
                                          • I concluded that the
