DL470 NM-B021
Rev: 2.0
Serial number: PF-0VNPA3
Type: 20J5-S1FL00

Corrupted the original bios and have been flashing a few recommended ones, Enter key seems to not work and Windows not picking up correct drivers. I don't have original BIOS :/

EDIT: Attached dump of original bios, it would turn on but backlight wouldnt even turn on, basically didn't POST.

Answering to myself...

Get an EC content from another L470, transferred only the DMI info from my backup and Computrace is gone.
