by AustinCERHello, I currently have a Dell XPS 8940 in our office for repair.
Service Tag: HG1Y673
The most recent BIOS is pictured below -- being available as an .exe on Dell website.
Needed a new motherboard due to power surge. The motherboard replacement was installed and upon power up it was booting to a display message - Manufacturing Mode Active -
Have not dealt with this issue before or what the proper steps are. I booted to the BIOS and manually entered the Service Tag, but upon each reboot -- the service tag is wiped and shows the Manufacturing Mode display message,...4 Photos-

by thesameThe tv is stuck in service mode, i have unpluged it for several times, tryed to power it separate from remote , tryed some reset method using menu button and 4725 typed twice in a row to enter or disable the service mode but it didn't work. The board has no damaged components, could it need a fresh firmware or the emmc could be dead?...
