          Remove the pass with Rex98`s 8FC8 patcher ,you`ll find a link to that in the Bios Guides sticky thread. Remove computrace/absolute https://www.badcaps.net/forum/troubl...79#post3633379

              1st boot, press F2, write service tag, disable Absolute, save, restart.
              2nd boot press Alt+F to exit manufacturing mode.
              Good luck.

                        I just wanted to say thank you for the 8CF8 patcher. I am new to this forum, but very technical, so the process of working off the WSON8 with a Weller hot air gun and patching the BIOS worked very well. I was able to achieve admin access on a DELL Latitude 5450.

                                          Dell Latitude 5400 Chromebook UEFI bios
                                          by jhanra
                                          Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.

                                          so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
                                          in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅...

                                          Dell Latitude 5530 BIOS Password Removal Attempted but I Broke the Laptop
                                          by TopPop
                                          Sorry for the long story. I have a Dell Latitude 5530 (i7) laptop (South Peak 15 MLK MB DDR4 203102-1 FK8VG$JA) with an admin BIOS password that I want to remove. Service Tag: HYKFPT3. Other than that the laptop worked OK.

                                          I found a CH341A Black and went looking for the BIOS chip on the motherboard. After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip...

                                          Dell Latitude 5431 issues with dumping bios
                                          by Sathsul
                                          So, i kinda spend significant ammount of the last couple of days trying to flash a new bios, and or unlocking the current bios password with little to no results.
                                          The whole thing started with it being the 8fc8 bios, i found the tools to unlock that but i needed a bios dump. So i pursued that, im at a point where i dessoudered the chip, and succesfully soudered it to the ch341, dumped whatever was on it.
                                          However, the tools supposed to unlock the 8fc8 say that there is no 8fc8 hex inside. And when i followed diffrent tutorials to just flash a new bios onto the chip i got stuck on the...
