About this board
Dell latitude 3520 Cyborg -L15 TGL — motherboard 203070-1.
Dell had this board built by Wistron; Wistron board numbers are 5–6 digits plus a revision. Check the number printed on the PCB before you download.
What this thread covers
- BIOS (full SPI chip dump, .bin)
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 203070-1 in File Finder.
