What is the Kindle Fire Utility and how do I use it?

VashyPooh, a Windows developer, recently launched Kindle Fire Utility. It enables users to root their Amazon Kindle Fire tablet, change boot modes, instal the TWRP custom recovery tool, and make other modifications.

Update: Kindle Fire Utility 0.9.5 now allows you to root Kindle Fire tablets running software version 6.3.1 or earlier.

Then Amazon published a large software upgrade that caused the rooting tools that individuals had been using to cease working. BurritoRoot, a new tool from developer jcase, is a little more hard to use than Kindle Fire Utility… but it’s now just as simple to use, thanks to BurritoRoot being included into the current version of VashyPooh’s utility.

You can root a Kindle Fire running OS version 6.2.1 or older if you download Kindle Fire Utility 0.7 or later.

You can root your tablet temporarily, permanently root it and instal Superuser, obtain the newest stock update from Amazon, or instal the latest version of TWRP, which allows you to flash custom firmware and even replace the operating system with CyanogenMod or other software.

To get started using Kindle Fire Utility, simply download the most recent version from xda-developers, unzip it to a directory on your computer, then run the run.bat file.

If your device isn’t recognised, you may need to instal the Kindle Fire drivers on your computer using the provided script. If that doesn’t work, see our original (and somewhat ancient) tutorial on rooting the Kindle Fire for information on installing ADB.

Also, if you’ve already rooted your Kindle Fire with BurritoRoot, make sure you uninstall it before installing Kindle Fire Utility 0.7.

How can I enter fastboot mode on my Kindle Fire?

The VID, PID, and REV are the three digits that Windows uses to identify each USB device.

When the Kindle Fire’s bootloader is active, just these two sets of hardware identifying numbers will appear.

If the numbers differ in any way, the bootloader is no longer in control of the device, and hence fastboot mode is not available.

To retrieve a list of all connected USB devices on Linux, type “lsusb -v.”

idVendor, idProduct, and bcdDevice are the relevant IDs.

Users of Mac OS X can use “system profiler SPUSBDataType,” and those IDs will appear in the list as Vendor ID, Product ID, and Version.

The numbers are structured a little differently than their Windows counterparts, but they’re easy to figure out.

In reality, there are three ways to enable fastboot mode on a functional bootloader.

There is a fourth technique, but it should only be used as a last resort because getting to the motherboard requires opening the case.

Let’s take a look at the first three techniques…

Factory cable – The most basic method of enabling fastboot mode on the Kindle Fire is to use a factory cable, which works with any bootloader.

Plug the cord into the Kindle Fire while it is turned off, and the PC and the tablet will both boot up into fastboot mode.

There is no need for the user to do anything else.

Temporary fastboot mode – The FireFirefire modified bootloader allows fastboot mode to be enabled for a limited duration.

Using the fastboot command…

  • Remove the screen from the base by unscrewing it. At the top in the middle, there’s a screw buried beneath the glue.
  • Connect tin wire to USB TTY device (order is ground, RX, TX from the perspective of the kindle, with GND being the smallest pad) and plug USB TTY device onto your computer.
  • Open Putty in serial mode on your PC, with the serial port set to your USB device and the baud rate set to 115200.
  • There is a small window when the kindle is booting up where transmitting data to it through the serial connection will force it to enter its bootloader. As my kindle began to boot up, I repeatedly pressed enter on my computer’s keyboard.
  • Run ‘bist fastboot’ to set your Kindle into fastboot mode now that we’re in the bootloader.

From the “Exit, Reboot, or Disable Diags” menu, reboot your kindle into diagnostics mode once more.

If you observe the serial output of your Kindle when it boots, you should see something like this.

This signifies that the system partition is being flashed. It will take some time, and the Kindle will only display the Amazon Kindle screen during that time.

Open “Exit, Reboot, or Disable Diags” after diags mode has booted, then disable diagnostics, then proceed. This will bring your kindle back to life.

Delete the mmcblk0p1.img file on your Kindle via USB if desired. If you keep it there, the diags utility will flash it to the system partition every time you run it.

How do I get out of a boot loop on my Kindle Fire?

Turn the device off and charge it until the indicator light changes to green, indicating that the battery is fully charged. Depending on the Kindle Fire model you have and the amount of power the battery started with, this could take up to five hours.

To do a hard reset, press and hold the power button for 20 to 30 seconds. This reboots the device and typically fixes the issues that create a boot loop.

To make sure the Kindle is operating, turn it on. Contact Amazon to request a repair if the looping continues.

On a Kindle, what is Fastboot mode?

Unfortunately, the devices aren’t flawless, and customers frequently have problems. When you’re using your tablet every day, things can get a little messy, from a lack of Google-supported apps to charging troubles.

One of the worst things that may happen to your smartphone is becoming trapped in Fastboot mode, which is a separate bootable version of Android that allows you to adjust the basic settings of Android without having to go through the normal boot procedure. Fastboot isn’t required for most Fire Tablet users, which makes being stuck in the mode all the more frustrating. Let’s look at how to return a device stuck in Fastboot to its default home screen.

On a Kindle Paperwhite, how do you conduct a hard reset?

1. Make sure your Kindle Paperwhite has a full charge by charging it if necessary before continuing.

2. With your device turned on, hit the Menu button in the upper right-hand corner of the screen, which appears as three horizontally stacked lines.

3. Select “Settings” from the drop-down menu.

4. Return to the Settings screen and tap the Menu button, then “Reset Device.”

5. You will be told that all of your device data will be deleted and asked to confirm your intention to reset your device in the dialogue box that appears. To begin the resetting process, select “Yes.”

When your Kindle Paperwhite resets, you’ll have to re-enter your Wi-Fi and Amazon account details as if it were brand new out of the box.

What should you do if your Kindle refuses to open?

Most of the time, if your Kindle device won’t switch on, that doesn’t indicate it’s “broken” or has an issue. Most electronic gadgets, including smartphones and tablets, have a tendency to become “stuck.” When a device becomes “stuck,” the power is turned on, but the item will not function correctly because it is locked up.

Resetting your Kindle device is one of the simplest and fastest ways to unlock it. Press and hold the power button for at least 20 seconds. Then, by pressing the power button once more, turn the device back on. If this doesn’t work the first time, try holding the button down for at least 30 seconds. Most of the time, this is all you’ll need to do to get your Kindle Fire up and running again.

If soft resetting doesn’t work and the device continues to lock up, you can restore factory settings to erase all data and apps. Press “More” > “Device” > “Reset to Factory Defaults” after tapping the “Quick Settings” button.

Please bear in mind that this will erase all data on your device, though you will be able to download the purchased apps or books from Amazon Cloud afterwards.

Charging or battery issues – Recharge the device or replace the battery

Another typical cause of Kindle not turning on is a low battery; unless you charge the device, it will not turn on. Wait 30 minutes after plugging the Kindle device into your computer before attempting to turn it on again. If the device still won’t turn on, try resetting it.

It’s conceivable that you have a broken charging cord if it still won’t switch on.

The quality of the wires that come with the Kindle is questionable. To see if the tablet responds, try charging it with another wire that has a Micro USB connector. The charging cord from your smartphone or tablet (Android Device) should work with the Kindle in most cases.

Another possibility is that the battery is damaged, in which case you will need to replace it. Here’s a picture instruction to replacing the battery on your own: Kindle Fire Battery Replacement, but if you’re having trouble, you should seek expert assistance.

Broken device – Fix the broken part by yourself

If neither resetting nor charging the gadget fixes the problem, the device’s hardware may have failed, and you’ll need to have it serviced or replaced. The Kindle Fire is difficult to open and repair, so unless you have prior knowledge in electronics repair, contact Amazon to arrange for service. However, if you want to do it yourself, you can watch several YouTube video lessons.

Here’s a video that shows you how to take apart and disassemble the Kindle Fire HD. Whether you need to replace a faulty battery or repair a broken item, this video will show you how to do it.

Contact Amazon Customer Service or Local Repair Technicians

If your Kindle device still does not turn on after all of these tries, or if you believe it is too difficult to repair the broken part yourself, you can visit the Kindle official help website for more information or contact Kindle customer support for assistance.

You can also go to the Kindle page on Facebook. Perhaps it will provide you with a quick solution to your troubles.

If your Kindle’s One-Year Limited Warranty has expired, or you believe it would be more convenient, consider contacting local Kindle professionals to repair your device.
