Custom ROM for Phone Farms: Auto-Boot, ADB Persistence, and Lab Hardening

**Common ROM requests** - Auto power-on after AC connect - ADB debugging persists without on-screen prompts - Disable OTA nag screens in locked-down labs - Extended screen timeout defaults **Why it matters** Phone farms reboot after outages. Without ROM hardening, operators re-authorize dozens of devices manually. **Scope limits** Advanced per-app hooks or carrier-specific builds quoted separately. We confirm board model compatibility before flash. **Coordination** Send target software stack (group-control tool, mirror client) in RFQ so ROM matches your automation workflow.
