Hello, I have a Dell 5520 Core i5
ST: DJX0KL3-3FE2 and I can't format it because it has an administrator password.
Southpeak15 TGL MB 8L 1819-1. 82G7H$KA.

Hi colleagues, I tried all your files; I decided to use one that actually works, but it boots up locked—I’ve attached it below. If someone could just remove the password—that’s all I need—I’d really appreciate it. I’ve been struggling with this device for a week now, please

hello, can someone help me fix this bios, it does not detect any hard disk. it does not detect nvme and msata. Latitude 5520 service tag 5LG6QG3 I also tried to program another bios but it does not start only with the original one. I tried to do a recovery from the usb-stick but it did not work, it gives an error that it does not support downgrade

thanks right now

[steve taylor]

it doesn't work, after the dell logo appears, it goes into a reboot loop, and gives an error of 3amber+5white, I forgot to say, before I used patch to remove the password

it doesn't work, endless reboot loop, no image, only the LEDs on the keyboard. the power button doesn't respond anymore, I think, I couldn't force it to turn off

[steve taylor]

I have had several of this model, it is the only one that does not work, only with its original bios, but it does not recognize any kind of storage

What model number is the CPU and full motherboard model, for example - Southpeak15 TGL MB 8L 1819-1. 82G7H$KA

[steve taylor]

yes, it is the board you mentioned, is there any other programmable component, ex:EC, that doesn't let it start with only the original bios?

SRK03 Performance Frequency: 2.6 GHz TDP-down Frequency: 1100 MHz Turbo Clock: up to 4.4 GHz All-Core Turbo: up to 3,8 GHz Base Clock: 100 MHz( i5-1145G7 Processor )

Try this bios.

Bad news, it doesn't work, freezes at the dell logo, but I found the old bios with the password and ran the patch, it started without any problems but it doesn't recognize the msata/nvme hard drive. I took all the hard drives I had, finally a 480gb APACER appeared in the bios and could be installed. A very strange case that I can't find an explanation for. Thank you for your effort.
