F7 Requires Full Erase¶

OpenBLT approach¶

Good news from 2025: use OpenBLT programming option

While most rusEFI units support incremental firmware update while keeping settings intact we are facing unexplained issue with some F7 Proteus units. Those units require full erase prior to software update.

Older approach before OpenBLT¶

Step 1: enter DFU option a: in rusEFI console use "switch to DFU mode" option b: open case, power ECU while holding "PROG" button to enter manual DFU

Step 2: full erase in rusEFI console use "Full Erase Chip"

Step 3: Manual DFU programming using rusEFI console as usual
