iCenter Card FixerCheck a card's data.ext3 · repair it in stages · clone identity onto a fresh unit

⚙ Engineering tool — makes a deliberately broken card for the boot-loop fuse sweep. Not for field use.

Generate a poison test card

Trims the source card (up to 2,870,513 readings/log) down to the line count you pick, then sets the ledger counter 3 ahead of the logs so the unit enters the boot-loop scan. The image comes back gzipped (tens of MB).

Sweep idea: start ~750,000 and step +100,000. Both dead 80-compartment units looped by ~1.64 M readings, so the tipping point is below that.

The card is never changed directly — you upload a copy of its data.ext3 and download a repaired one to write back. The original file on the card stays put until you replace it.
