About this board

This thread is for the HP EliteBook 820 G4 6070B0886101.

Compare the board number printed on the PCB (near the RAM slots or under the battery) with the files before you flash. Board revision: 1.04. Match the revision as well as the board number.

Files usually needed for this board
  • BIOS (full SPI chip dump, .bin)
  • EC / KBC firmware, if the board uses a separate EC chip
  • Schematic (PDF)
  • Boardview (.brd / .bdv / .cad)

Typical reasons to reflash: no power or no display after a failed BIOS update, a BIOS/supervisor password lock, or a corrupted Intel ME region.

Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.

If you have a working file for this board, please share it below. More files: search HP EliteBook 820 G4 6070B0886101 in File Finder.
