Controlled flashing
The app avoids exposing risky actions too early. Write options stay locked until identify, first read, VIN, ECU profile, stock backup, and server authorization are in place.
Server write plans
Stage 1, Stage 2, and custom files are selected through the account workflow. The flasher receives a prepared plan instead of guessing checksum and vehicle state locally.
Backup first
The first read becomes the baseline for future recovery, support, and calibration decisions. Normal read/write actions appear only after that baseline exists.
Workflow
Simple on screen. Strict underneath.
Drivers see VIN, model, connection state, and the next available action. Internal plans, license IDs, prepared file names, and debug sync state stay out of the customer UI.
