I recently had a Firmware update in a book scanner, CZUR ET series, that was done remotely by the manufacturer of the device. It is a versatile and good scanner for archiving old books, manuscripts, etc. I was having problems while scanning when I used a hand button and or a foot paddle (USB connection to the scanner). Scanning was interrupted due to complete freezing of the scanning application. However, I did not have any freeze when I was using the computer mouse instead of the scanner buttons. My computer system was Mac OS 10.14.X. Amazon agreed to replace the scanner with a new one without a fuss. It was beyond the money refund period. I did not want to get a refund. Other brans similar scanners cost much more and I needed a book scanner. But I did not know whether the new replacement would have the same issue. I contacted the manufacturer. Our time difference is +12 hours. The manufacturer told me that a special tool would be needed to fix the problem remotely. There was no need to send the scanner back for repair. The manufacturer send a link and I had to install TeamViewer software and created an account. I gave my account information, a static user ID and a dynamic PW from TeamViewer application, to CZUR. The scanner was attached to Mac via USB port. I had to sit at night and someone from the other end gave me step by step instructions (Chat conversation within TeamViewer application) to update Firmware in CZUR scanner. It took about 15-20 minutes for Firmware update. Since then I tested the scanner once only. I did not encounter any freeze when I used the scanner button and Magic Mouse. It seems Firmware update is very important. CZUR scanner is new in the market and thus it needed regular Firmware update to workweek with every OS. I perhaps do not need a replacement scanner anymore. Though, I have not received it yet, I have been thinking to cancel the replacement order after testing the scanner a few more times. This is a very nicely written Firmware article. Thank you!

Very nicely explained!

Thanks, this toturial helped me a lot.

I would like to know more…

Thanks for the useful article. Great explanation!

It is a very good article. Comparison clears confusion.

this is how you explain….other people just keep on defining software, hardware and firmware … but no one said if no firmware in electronic device it is dumb and won’t function or will be just like electric switch…on and off..

Thanks!

A great explanation – nice work!

Excellent article. Clear and concise.

It’s very informative. Keep up the good work.

My phone wants to uninstall the Motorola sensor services firmware…what does this mean?

Thank you that was very helpful period I’m not very tech-savvy period I just got my first smartphone 1 year ago. When I see a message on my Galaxy instructing me to download firmware… I got nervous. I still have a question. Is it possible for some maniac to insert a message on my smartphone telling me it’s firmware and perhaps it is not for the good of my phone or for me? If the firmware doesn’t identify where it comes from and you can’t fully vet it – how do you know it’s not some hack trying to put a bug in your phone? Thank you in advance.

thanks helped alot
