Hello everyone, i got Dell Latitude 3520 with admin pass, i used the "BadCaps 8FC8 Patcher" and no more admin pass, now the step to enter Service Tag is an issue, no stickers on device that has it, also before doing bios changes, i could not get into bios to take a pic of service tag, so with my original bios backup, can someone maybe help me find it please. btw i tried the tool on github "DellBIOSTools" but all tags it gave me are wrong.
