A Firmware and Support Record for Your Home Devices
Assign one row to each device model and hardware revision. Record the installed firmware from the device itself, not an old shopping listing.
Start with your own situation
Assign one row to each device model and hardware revision. Record the installed firmware from the device itself, not an old shopping listing.
Work through the record
Save the vendor support URL and the date you checked it. Distinguish an available update from a published support end date; if no date is stated, write not stated.
Your printable worksheet
Use one sheet per firmware and support record. Fill these fields: Device / hardware revision / installed version / vendor URL / checked date / published support statement. Leave missing information marked unknown; do not silently substitute an estimate.
Make the next decision
Review the vendor instructions before any update and record the outcome only after it completes. This inventory tracks support evidence; it does not promise continued support or security.
