Question 1

How long is too long for a firmware update?

Accepted Answer

Use the last column of the table above. Roughly: 10 minutes for a BIOS update, 15 for a router, 30 for a TV or printer, 45 for a console. Below those numbers, waiting is the right move even when the screen has not changed.

Question 2

Will unplugging it ruin my device?

Accepted Answer

It depends entirely on which stage it had reached. During the download or after the restart, unplugging is harmless. During the write — the stage you cannot see from outside — it is what causes bricked hardware. Since you cannot tell which stage it is in, waiting first is the only safe policy.

Question 3

Does a failed update void the warranty?

Accepted Answer

A failure during the manufacturer's own official update normally does not — that is a fault in something they asked you to do. What can affect a claim is what you do next: unofficial firmware, opening the case, or hardware flashing tools. Contact support before going down that road, and check your warranty terms, which vary by manufacturer and country.

Question 4

Can a failed firmware update be fixed at home?

Accepted Answer

Often, yes. If the device still shows any sign of life — a light pattern, a recovery screen, an entry on your network — there is usually a documented route back, most often a USB stick or a reset-button combination. If it is completely inert, home repair is unlikely and the manufacturer is the next call.

Question 5

The update failed and now the device works fine — should I retry?

Accepted Answer

This is the most common outcome, and it means the update failed safely before the write stage. Retry it — but on a wired connection if possible, with storage freed up, and not on the day a major release ships when the manufacturer's servers are overloaded.
