About this board
This thread is for the Dell Latitude 3420 cyborg-l14 TGL NEW with main board 213105-1.
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.
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)
Common cases: dead board after an interrupted BIOS update, ME region errors, missing serial number or UUID after a board swap, or a password lock.
Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.
