Overview

Interrupted updates can leave a device sensitive to additional failures. Follow a disciplined retry policy; avoid repeated blind attempts.

Capture exact error text, time, source/target firmware versions, phone OS, app version.
Charge device and reboot once using approved procedure if responsive.
Retry official recovery path in-app once if your playbook allows.
If two careful attempts fail, stop and escalate with the full bundle; do not improvise flashing.
