“A failed update can brick a deployed product.”
Devices stop booting, loop through resets, or need a cable to reflash them.
Engineering service / Fleet infrastructure
Firmware updates should not leave devices offline.
Hughie Systems develops and repairs over-the-air update systems, from device firmware and bootloaders to fleet release controls.

When to bring us in
When failed updates turn into site visits and manual reflashing.
Bring us in when updates need hands-on intervention, factory setup is inconsistent, or support cannot tell which devices completed a release.
“Factory setup still depends on manual steps.”
Credentials, configuration, and manufacturing records vary between units.
“The update says success, but the device is still on the old version.”
The dashboard reports download completion without confirming what actually booted.
“Updates fail whenever the cellular connection drops.”
Downloads restart from scratch after a dropped connection, or offline devices miss the release.
Scope
What we build and fix.
The scope can be a specific update failure or a new deployment system. Work is bounded by your hardware, existing backend, and release requirements.
01 / UPDATE ARCHITECTURE
Safe installation and activation
Implement image validation, interruption-tolerant transfer and installation, boot selection, and rollback within the device's flash and bootloader constraints.
02 / PROVISIONING
Device identity and factory flow
Automate identity, credential, and configuration setup, with records linking each manufactured unit to its fleet entry.
03 / RELEASE CONTROL
Eligibility, staging, and observability
Target compatible devices, stage releases in small groups, distinguish installation from confirmed activation, and stop a rollout when health checks fail.
04 / FIELD OPERATIONS
Remote diagnosis and recovery
Expose versions, failure logs, and command history. Define bounded retries and remote recovery where hardware permits, with a documented physical recovery procedure when it does not.
Handoff
Code, test evidence, and release instructions.
Implemented changesFirmware and integration changes with the design decisions and hardware limitations documented.
Failure-case resultsEvidence from tests covering power cuts, dropped links, incompatible images, and failed startup, as applicable to the scope.
Operating proceduresInstructions for releasing firmware, interpreting device status, and responding when a deployment fails.
