If your Firestick keeps restarting, then use this simple fix-it guide to repair your Amazon Fire Stick or Fire TV.

Several things can cause Firestick restart problems, such as an inadequate power cube (aka “power block” or “wall wart”).

Example for techies: For example, some people use an after-market power supply block for their Firestick which provides 5 VDC (5 volts of direct current) and 0.7 Amps. This results in the Firestick receiving only 3.5 Watts of power (5 Volts X 0.7Amps = 3.5 Watts). Basically, in this case, you need to use a different power adapter (view on Amazon). This is all covered in the fixes below.

IMPORTANT: Install a VPN on your Firestick to fix privacy leaks and other issues in the Firestick apps you use.

TL;DR (The solution): Don’t worry! Just try the solutions below to fix your Firestick keeps restarting problems.

Fix #1: Make Sure You’re Using Official Firestick Accessories

If you’re like me, you tend to use “whatever USB cable is laying around” instead of the “official” USB cable for your device.

Don’t do this with Amazon Firestick! Instead, use the power cable and power block that came with your Firestick.

This is the OFFICIAL (aka “stock”) power supply that ships with Firestick. Try it!

Why? Because the official USB adapter for the Firestick has a certain amount of power it provides to the device.

So if you use an off-brand USB cable or power block to power your Firestick and your Firestick keeps restarting, then you can expect that the Firestick will not get enough power to stay on.

Fix #2: Use a Brand New USB Cable If Firestick Keeps Restarting

For MicroUSB cables (like the one that powers your Firestick), there’s definitely a life span. If you use an old Micro USB cable to power your Firestick, consider the possibility that it may simply no longer be working well enough to provide the necessary power to your Amazon Fire Stick / Fire TV.

So just replace your USB cable with a brand new Micro USB cable – it might do the trick!

Fix #3: Try Using a 2 Amp Power Adapter

WARNING: Beware! We are not responsible for any damage done to your device if you supply too much power to your device.

The Amazon Firestick ships with a 1 Amp power adapter. If your Firestick keeps restarting, then try to use a 2 Amp power adapter instead. This is definitely the case for the (larger) Amazon Fire TV, which requires a 2 Amp power adapter.

Try a USB hub that provides “quick charging”

Some users report that they had to switch their power supply to a “fast charger” (which typically provides 2.1 Amps to the Firestick).

Fix #4: Plug The Power Adapter Directly Into a Power Outlet

Many Firestick users plug their Firestick’s power cable into the USB port on the back of their TV (or into a power block that powers your phone, for example).

Plug Firestick directly into the power outlet

What’s the problem with plugging Firestick into your TVs USB port?

Well, anything other than an actual power outlet may provide an “inconsistent” stream of electricity to your device. So, if your Firestick keeps restarting, just plug your Firestick USB power cord directly into a power outlet (and nothing else).

Fix #5: Disconnect Any USB Extension Cables

If you have a USB extension cable plugged into your Firestick power adapter, remove it!

Why? Because USB extension cables provide different amounts of power. So if you use an extension cord that does not provide the necessary amount of power for your Amazon Firestick / Fire TV, then simply remove the extension cord so your Fire Stick gets the power it needs.

This USB extender issue is a common cause of the Firestick keeps restarting issue.

Fix #6: Remove Other Devices Connected To Your TV’s HDMI Ports

It’s likely that your TV has more than one HDMI port. Therefore, it’s also likely that you have at least two HDMI devices plugged into your TV.

It’s possible that another HDMI device is interfering with the streaming “signal” coming from your Firestick, resulting in Firestick keeps restarting problems. Yes – all TV’s were not created equally. Some TVs don’t deal with multiple HDMI devices very well.

Unplug non-Firestick devices from your TVs other HDMI ports

If your Amazon Firestick keeps restarting, then unplug all other HDMI devices so that your Fire TV Stick is the only connected HDMI device.

Basically, if this fixes the problem, then you know one of the other HDMI devices was causing the Firestick keeps restarting issue. At this point, you simply plug the other HDMI devices in one-by-one to see which of them was causing the problem.

TIP: We also recommend that you replace your Firestick HDMI cable.

Fix #7: Disable HDMI CEC

Are you aware that you can use your TV remote to control your Firestick (for navigation, etc)? It’s true! And it’s called HDMI CEC.

The HDMI CEC feature is a way for your TV to control your Firestick. So it’s possible the HDMI CEC feature is interfering with your Firestick performance.

Therefore, you should disable HDMI CEC on your Firestick (in the Settings menu) to see if that fixes the Firestick keeps restarting problem.

Here’s how to disable HDMI CEC on Firestick:

  1. Go to Settings

    Settings on Firestick Home screen

    Select “Settings” from the Firestick home screen

  2. Select Display & Sounds

    Firestick Display & Sounds for Screen Mirroring with Android & iPhone

    Select “Display & Sounds”

  3. Choose “HDMI CEC Device Control” and make sure it’s switched OFF.

    Disable HDMI CEC on Firestick

    Turn off HDMI CEC control

Fix #8: Make Sure Firestick Is Up-To-Date

It’s possible that there’s a bug in the software that makes your Firestick run. This is why Amazon periodically releases “system updates” for its devices (such as Fire Stick and Fire TV).

So just update Fire TV Stick to ensure that you’re using the latest software available for your device and can fix your issues if the Amazon Firestick keeps restarting.

To update Firestick, do these steps:

  1. Go to Settings

    Select Settings from the Amazon Fire stick home screen

    Select “Settings”

  2. Select “My Fire TV
  3. Choose “About
  4. Press “Check for System update

Fix #9: Reset Your Firestick

One of the most common reasons Amazon Firestick keeps restarting is that you simply have too many apps installed.

The easiest way to fix this is to reset your Fire Stick. This is also known as a Factory Reset (or “reset to Factory default settings”).

To reset Firestick, do this:

  1. Go to Settings

    Settings on Firestick Home screen

    Go to Settings

  2. Select “My Fire TV
  3. Choose “Reset to Factory Defaults” and wait for your device to reset.

    Reset Firestick to Factory Defaults

    Wait until this message goes away for Firestick to reset

Fix #10: Try a Different Firestick

Sometimes Amazon Firestick can simply just “die”, or become “incapacitated”. Many peoples’ Amazon Firestick suffers constant and/or repeated overheating, which leads to device failure.

You can get a brand new 4K Firestick for $50 or less right here on Amazon.

  • It’s like how if your car constantly overheats, the engine will eventually break down and cease to function properly. Electronic devices work in the same way! There’s a lot of heat being generated by the device, and overheating causes devices to fail.

    Firestick overheating

    Is your Firestick overheating? Check now! If it’s warm to the touch, it’s probably overheating.

Therefore, try a different Firestick to see if the same thing is happening. If the 2nd Firestick keeps restarting, then it’s likely that the problem is not with the Firestick, but with the power that is being supplied to it.

Fix #11: Restart Your Firestick Using The Fire TV Remote

Best Fire Stick Hacks

Follow the steps below to restart Firestick with the remote

Known as a soft reset, you can reset your device using the Fire TV remote. This is an alternative to unplugging the power cord from your device.

To do a soft reset, follow these steps:

  1. Press down (and hold down) the PLAY button and SELECT button at the same time
  2. Keep holding them down until your screen displays a message

To do a HARD reset, follow these steps:

  1. Press and hold down the SELECT button, the RIGHT button, BACK button, and REVERSE (aka “rewind”) button
  2. Wait for Firestick to display a message / reset itself

It may feel counter intuitive to combat Firestick keeps restarting issues by restarting your Firestick, but we’ve seen it work. Give it a shot!

Fix #12: Try a Different TV

Sometimes the TV you use is causing a problem with your Firestick (or the TV is just incompatible with some devices). To test this, try your Amazon Firestick on a different TV.

Sometimes a TV is no good and causes Fire TV restarting issues

Also, many TVs produce a lot of heat which can be emitted onto the Firestick, causing the Firestick to restart. If this is the case, use the HDMI extension cord that came with your Firestick to give your Firestick some distance away from your TV.

Fix #13: Replace The Fire TV Remote Batteries If Firestick Keeps Restarting

While this is not a common issue, it’s possible that low battery power in the Firestick remote can cause the remote to “glitch” and send a restart signal to your Firestick.

If you’re having any Firestick remote issues, aside from your Firestick keeps restarting problems, then check out my Firestick remote stopped working guide.
