''Do not unplug the USB connection until the process is complete ''

The above has appeared on mobile phone - when phone was plugged in to charge battery

What is Firmware update ?

And like hardware only softer.

It's your phones operating system which keeps things secure and up to date. Amongst other things.

Software is programming that is stored on your hard disk and which you copy into volitile RAM memory when using.

Firmware is programming stored on integrated circuit chips, probable non-volitile memory, on your circuit board so it's always there ready to use from power up. It rarely needs upgrading, and if you do so do it with care, because an interruption could ruin whatever drives your tech, in this case a mobile phone, and probably result in you taking it to a workshop for recovery.

now you tell me
Charger was removed before message was seen

//''Do not unplug the USB connection until the process is
complete '' //
Would that include the charger ?

If your battery was in a semi charged state it will be fine .. the reason they say "do not remove charger" is because, should your battery be discharged and you were updating over wifi, your update would fail if your battery went flat.
If the charger is connected during the update, then there is no chance of battery going flat and interupting the update.
