Tablet Stuck in Fastboot Mode: Restart It Safely

Updated 6 November 2026 · Standard formula, shown below

If your tablet is stuck on a fastboot screen, it means the bootloader is waiting for a command and will not boot the operating system on its own. The safe way to restart it is to hold the power button for 10–20 seconds to force a shutdown, then press the power button again to boot normally. If that does not work, you can issue the fastboot reboot command from a computer, or use the volume keys to select “Restart” or “Reboot” from the fastboot menu.

What Is Fastboot Mode?

Fastboot is a diagnostic and flashing protocol built into Android devices (and some other tablets) that runs before the operating system loads. It is part of the bootloader—a small program that tells the device how to start. When you enter fastboot, the device shows a screen with the manufacturer logo and often the words “FASTBOOT” or “fastboot mode,” along with options like Start, Restart, and Recovery. In this state, the tablet’s normal Android system is not running, so the touchscreen and most buttons do not work as they normally would.

Fastboot is primarily used by developers and technicians to unlock the bootloader, flash custom recoveries, install system images, or wipe data. It is also the mode that appears when a system update fails or when the bootloader is waiting for a command that never comes.

Why Does a Tablet Get Stuck in Fastboot?

There are several common reasons a tablet ends up stuck on the fastboot screen:

Accidental key combination: Holding Volume Down + Power during a reboot can trigger fastboot on many devices.
Interrupted system update: If an update is interrupted or fails, the bootloader may drop into fastboot instead of booting normally.
Corrupted boot image: A damaged boot partition can prevent the system from starting, leaving the device in fastboot.
Software flashing gone wrong: A failed attempt to unlock the bootloader or flash a custom ROM can leave the device stuck.
USB command left waiting: If you connected the tablet to a computer and ran a fastboot command that never completed, the device will stay in fastboot indefinitely.

In most cases, the device is not bricked—it is simply waiting for a command that will never come. The fix is usually simple.

How to Restart a Tablet Stuck in Fastboot (Step-by-Step)

Try these methods in order, from least invasive to most involved. Stop as soon as the device boots normally.

Force a shutdown: Press and hold the Power button for 10–20 seconds. The screen should go black. Wait a few seconds, then press Power again to turn it on. This works on most tablets because the bootloader responds to a long press as a hard reset.
Use the fastboot menu: If the screen shows options, use the Volume keys to highlight “Restart” or “Reboot” and press the Power button to select it. If the screen is unresponsive, skip to the next step.
Issue the reboot command from a computer: Connect the tablet to a computer via USB. On the computer, open a command prompt (Windows) or terminal (macOS/Linux) and type fastboot reboot. If the command is not recognized, you may need to install the Android platform-tools or the correct USB driver for your device.
Use the recovery menu: If fastboot commands do not work, force a shutdown, then press and hold Volume Up + Power (or the combination for your device) to enter Recovery Mode. From there, select “Reboot system now.” This often clears the stuck state.
Let the battery drain: If nothing else works, leave the tablet off and unplugged until the battery is completely empty. Then charge it for a few minutes and turn it on. This is a last resort but can reset the bootloader state.

If the tablet still will not leave fastboot after these steps, the problem may be a corrupted boot partition or a hardware issue. In that case, you may need to reflash the stock firmware using the manufacturer’s official tool, or contact the device’s support service.

What to Do If the Tablet Won’t Boot After Leaving Fastboot

Sometimes the tablet exits fastboot but then loops back to it, or shows a “No command” error. This usually means the boot image is damaged. Here are some things to try:

Boot into Recovery Mode and select “Wipe cache partition” (this does not erase personal data).
Perform a factory reset from Recovery Mode if wiping the cache does not help. This will erase all data, so back up anything you can first.
Reinstall the operating system using the manufacturer’s official flashing tool. This is the most reliable way to restore a corrupted boot image.

If you are not comfortable with these steps, a repair shop can reflash the firmware for you.

Common Mistakes to Avoid

When dealing with fastboot, a few mistakes can make things worse:

Unplugging during a flash: If you are using fastboot to flash files, never disconnect the USB cable mid-process. This can corrupt the bootloader.
Using the wrong key combination: Pressing random buttons can trigger fastboot again. Look up the correct recovery key combo for your specific tablet model.
Ignoring the battery: A tablet with a very low battery may appear stuck in fastboot but is actually just out of power. Charge it for at least 30 minutes before trying anything else.
Assuming it is bricked: Fastboot is a recoverable state in most cases. Do not panic and attempt risky fixes without research.

Fastboot vs. Recovery Mode: What’s the Difference?

Fastboot and Recovery Mode are two different low-level menus. Fastboot is used to flash partitions and is controlled from a computer via USB. Recovery Mode is a standalone environment on the device itself that allows you to apply updates, wipe data, or reboot. If you are stuck in fastboot, you can often switch to Recovery Mode by selecting the “Recovery” option in the fastboot menu, or by pressing the correct key combination during a reboot. Recovery Mode is more user-friendly because it has a simple menu you can navigate with volume keys, whereas fastboot usually requires a computer to do anything useful.

Frequently Asked Questions

Will holding the power button for 20 seconds damage my tablet?

No. A long press on the power button is a standard hardware reset that simply cuts power and restarts the device. It does not harm the hardware or the software. It is the first thing to try when a device is unresponsive.

Do I need a computer to exit fastboot?

No. In most cases, a simple force restart (holding the power button) is enough. The computer method is only needed if the force restart does not work, or if you want to issue a specific command like fastboot reboot.

What if my tablet has a non-removable battery?

Most modern tablets have non-removable batteries, but the force restart method still works. Holding the power button for 10–20 seconds simulates a battery pull by cutting power to the system. If that fails, you can also try pressing and holding Power + Volume Down for 10 seconds.

Is my data gone if I’m stuck in fastboot?

No. Fastboot mode does not erase your data. Your files remain intact on the internal storage. The only way to lose data is if you choose to wipe data or reflash the firmware, which will erase the userdata partition.

Why does my tablet keep going back to fastboot after I restart it?

This usually indicates a corrupted boot image or a failed update. The bootloader cannot find a valid system to boot, so it returns to fastboot. You will need to reinstall the operating system using the manufacturer’s tool, or perform a factory reset from Recovery Mode if that is available.
