As a general rule, Amazon’s over-the-air updates are usually hiccup free (even though they might take upwards of a month to slowly roll out to every Kindle across the globe).
But maybe your Kindle stopped updating for no reason (like ours did), or maybe you’re just in a rush to get the latest and greatest features.
The first and foremost step is that you identify which Kindle you have in order to ensure you’re comparing the right software version for your model and downloading the appropriate update.
Rather than squint at the tiny model number on the back of your case and then Google the model number, the simplest method is to check the serial number as the first four alphanumeric characters indicate the model/generation of your Kindle.
Click on the link “Download Software Update [version number]”. Once the download is complete, attach your Kindle Paperwhite to your computer with a USB cable and copy the update .
Remember, there may be multiple versions of the same model—this is why we went searching for the serial number in step one. Clearly, the firmware version we have on our Paperwhite (5.6.1) is behind the most recent version as of this writing (5.8.5).
