Fix Bootloop on Android: 7 Working Methods

A bootloop is when your Android phone gets stuck on the startup logo and never reaches the home screen. The fix depends on the cause, but you can usually resolve it by clearing the cache, booting into Safe Mode, or performing a factory reset. This guide walks through the most effective methods, from least to most invasive, so you can get your device working again.

What Causes an Android Bootloop

Bootloops happen when the Android operating system fails to load completely, then tries again, over and over. Common causes include:

• Bad app update – a recently installed or updated app conflicts with the system.
• Corrupted system cache – temporary files that help apps load quickly become damaged.
• Failed system update – an interrupted or partial OS update leaves the system in an inconsistent state.
• Insufficient storage – the system can’t write necessary files because the storage is completely full.
• Hardware issues – a failing battery, loose flex cable, or damaged motherboard can also cause loops, though less commonly.
• Rooting or custom ROMs – modifying the system partition can lead to boot failures.

Knowing the likely cause helps you choose the right fix. If the loop started right after you installed an app, that app is the prime suspect. If it happened after a system update, the update may have failed.

Before You Start: Backup and Safety

Most bootloop fixes involve erasing data, so try to back up anything you can before proceeding. If your phone still shows the boot animation but never finishes, you may be able to connect it to a computer and copy files while it’s in recovery or download mode. If not, accept that data loss is possible.

Also, ensure your phone has at least a 50% charge. A phone that dies mid-fix can become permanently bricked. Keep it plugged into a charger during the process if possible.

Method 1: Force Restart

Sometimes the bootloop is a one-time glitch. A force restart clears the RAM and may get the system to boot properly.

1. Press and hold the Power button for 10–20 seconds until the screen goes black and the phone vibrates or restarts.
2. If that doesn’t work, press and hold Power + Volume Down for 10–15 seconds on most Samsung and Pixel devices. On some phones, it’s Power + Volume Up.
3. Release the buttons when the screen turns off, then let the phone restart normally.

This is the least risky fix and works for temporary software crashes. If the loop persists, move to the next method.

Method 2: Boot into Safe Mode

Safe Mode starts Android with only pre-installed apps. If the bootloop stops in Safe Mode, a third-party app is the culprit.

1. Turn off the phone completely. If it’s stuck, force restart first.
2. When the screen turns on, press and hold the Power button.
3. When the logo appears, release Power and immediately press and hold Volume Down.
4. Keep holding Volume Down until the home screen appears. You’ll see “Safe Mode” at the bottom.

In Safe Mode, go to Settings > Apps and uninstall any recently installed or updated apps. Then restart the phone normally. If the bootloop is gone, you’ve found the problem.

Method 3: Clear the Cache Partition

The cache partition stores temporary system files. If they’re corrupted, clearing them often fixes bootloops without deleting your personal data.

1. Turn off the phone.
2. Press and hold Power + Volume Up (or Power + Volume Down on some models) until the recovery menu appears.
3. Use the volume keys to navigate and the power button to select.
4. Choose Wipe cache partition (not “Wipe data/factory reset”!).
5. Confirm, then select Reboot system now.

This is safe and doesn’t erase your apps or files. It’s a common fix after failed OTA updates.

Method 4: Factory Reset (from Recovery)

If the above methods fail, a factory reset will clear all data and restore the phone to its out-of-the-box state. This usually fixes software-related bootloops.

1. Boot into recovery mode (same as above).
2. Select Wipe data/factory reset.
3. Confirm the action.
4. Then select Reboot system now.

This erases everything: photos, contacts, apps, and settings. If you have a Google account, your contacts and some settings may sync back after you sign in, but you’ll need to reinstall apps manually.

Method 5: Reflash the Stock Firmware

If a factory reset doesn’t work, the system firmware itself may be corrupted. Reflashing the official stock firmware can repair it. This requires a computer and manufacturer-specific tools.

1. Download the official firmware for your exact phone model from the manufacturer’s support site.
2. Install the flashing tool: Odin for Samsung, LG Bridge for LG, or Google’s Flash Tool for Pixel.
3. Put the phone into Download Mode (usually Power + Volume Down + Home on older devices, or just Power + Volume Down on newer ones).
4. Connect the phone to your PC and follow the tool’s instructions to flash the firmware.

This is more technical and can void your warranty, so proceed carefully. Always use the correct firmware for your model and region.

Method 6: Check for Hardware Issues

If none of the software fixes work, the bootloop may be hardware-related. Common culprits include:

• Battery failure – a swollen or dead battery can prevent the phone from getting enough power to boot.
• Loose connections – internal flex cables can come loose after a drop.
• Overheating – if the phone gets too hot, it may shut down and restart repeatedly.

Try charging the phone for a few hours with a different cable and adapter. If the battery is removable, take it out, wait a minute, and reinsert it. If the problem persists, contact a professional repair service.

Frequently Asked Questions

Will a factory reset delete my photos?

Yes, a factory reset erases all data stored on the phone’s internal storage, including photos. If your photos are backed up to Google Photos or another cloud service, you can restore them after the reset. If not, they’re gone.

Can a bootloop be caused by a virus?

It’s rare, but malicious apps can cause system instability. If you suspect malware, boot into Safe Mode and uninstall suspicious apps. A factory reset will also remove most malware.

How long should a phone stay in a bootloop before I give up?

Try each fix in order. A force restart takes seconds. Safe Mode and cache clearing take a few minutes each. If none work after a factory reset, the issue is likely hardware or deeply corrupted firmware, so consider reflashing or professional repair.

Does clearing the cache delete my apps?

No. Clearing the cache partition only removes temporary system files. Your apps, settings, and personal data remain intact.

Why does my phone bootloop after an update?

Updates can fail if the download is interrupted or if there’s not enough storage space. The system may be left in a partial state. Clearing the cache or performing a factory reset usually resolves it.

Is it safe to use third-party tools to fix a bootloop?

Only use tools from the phone manufacturer or well-known, reputable sources. Third-party tools can be risky and may brick your device. Always research before downloading.
