Amazon Kindle 4 D01100 E-Reader


I use an e-ink e-reader most days and for years my preferred device was a Kindle 3 Keyboard. However I purchased a lot of tablets on eBay as part of a job lot and one of them was the Kindle 4th generation (D01100/K4 NT) and I decided to switch over to it as my daily e-reader.

The Kindle 4 D01100 possibly came out in 2012 and yes it’s 2021 and I’m still using one! The old second-hand e-reader I purchased has a few marks, but I don’t care. The only thing I wish it had is an inbuilt light.

I own other Kindles, including two touch screen models, but I prefer the buttons on the D01100. I am going to keep the majority of my other Kindle e-readers for a while and might use some in projects. I might trade in, sell or even give some away locally.

I think my old Kindle Keyboard 3 is heavier and slower than the D01100, but I’m only moving on from my older Kindle as its battery doesn’t hold the charge that well and I don’t want to change the battery.

After I followed the steps below, I placed the Kindle D01100 into ‘airplane mode’ via settings, to help save the battery life, only turning on the WiFi when needed. I’ve placed the Kindle is in a case, so I hope I can prevent further damage to the surface.

If you also have a Kindle, please leave a comment below and I would like to read your views about the device.

How to update a Kindle D01100’s firmware

3rd Warning: Updating the firmware on a device is a risk and you could make your device unusable. If you do wish to update the firmware, you should also make sure the device has been fully charged first.

4th Warning: You can’t skip firmware versions and should only update to the next release. So if you want to update from version 4.1.1 to 4.1.3, you should update from 4.1.1 to 4.1.2 first and then 4.1.2 to 4.1.3.


Find out what the currently installed firmware is by pressing the menu button and then selecting ‘settings’. At the bottom right it should tell you the firmware version your D01100 is running.

Amazon host the firmware files for the Kindle D01100 here and here.

It should now update the Kindle’s firmware then reboot. I then did the same as the steps above for the next consecutive firmware versions.

Final thoughts

I’m a huge fan of Amazon Kindle e-readers and I use the Kindle 4 D01100 most days. I think its weight is good and it’s easy for me to carry around, but I mostly use it at home.

I like using the buttons on its side to turn the pages. I paid a very low price for this e-reader and I think I grabbed a bargain.
