If your LG L90 D405N smartphone is freezing, glitching, or you’re locked out of it, performing a hard reset (also known as a factory reset) can often resolve the issue. A hard reset will erase all your personal data, settings, and apps, restoring the phone to its original factory state. Make sure to backup any important data before proceeding. Here’s a step-by-step guide on how to hard reset your LG L90 D405N.

  • If you can’t access the Settings menu, turn off the phone, press and hold Volume Down + Power, release Power when the LG logo appears, then press Power again and Volume Down to enter the reset menu.
  • The LG L90 reset process itself takes about 5-10 minutes, but backing up and restoring data can significantly increase the total time.

Hard Reset LG L90 Using Hardware Keys

Nearly all Android phones, including the LG L90, have an option to reset using the physical buttons on the device. Here’s the process:

  1. Power off your LG L90 completely. If you can’t shut it down normally, wait until the battery goes dead, then charge it up to at least 5% capacity.
  2. Press and hold the Volume Down and Power buttons simultaneously.
  3. Once the LG logo appears, release the Power button for a second, then hold it down again. Keep holding Volume Down the whole time.
  4. You should see a factory data reset screen with Yes and No options at the bottom. Press Volume Down to highlight Yes, then press the Power button to select it.
  5. Your phone will reset and eventually boot up to the initial setup screen.

This method can be helpful if your LG L90 is frozen or won’t boot up properly. It’s a failsafe to factory reset if needed.

Restoring Your Backed Up Data

After resetting, you’ll have the option to restore data from a backup during the setup process:

  1. On the “Get your apps & data” screen, select “Restore from backup.”
  2. Choose the backup source – Google, LG Backup file, etc.
  3. Follow the prompts to restore your data and settings.

Keep in mind that restoring a backup will not restore everything – certain app data, music, and files may need to be transferred manually from a computer backup.

What to Do After Hard Resetting Your LG L90

After your phone finishes resetting and displays the welcome screen, you’ll need to go through the initial Android setup process again. Some tips for setting up your device:

  • Reconnect to Wi-Fi. You’ll need an internet connection to proceed.
  • Enter your Google account info. This will restore contacts, apps, and data backed up to your Google account.
  • Enter a screen lock. It’s always good practice to secure your device with a PIN, pattern, or password.
  • Restore your data. If you used LG Bridge or manual methods to backup your data, now’s the time to restore it to your freshly reset phone.
  • Reinstall apps. You’ll need to download apps again from the Google Play Store, but your app data and logins should be restored if backed up to Google.
  • Reconfigure settings. Go through the various settings menus and configure things like sound, display, battery, and accounts to your liking again.

It may take a bit of time, but when finished your LG L90 should be running like new again. Keep in mind, any data that wasn’t backed up will be missing, so take care to transfer over anything critical.

Alternatives to Factory Reset

If you’d rather not completely erase and reset your phone, there are some alternatives to try first:

  1. Safe Mode – Booting into safe mode temporarily disables all third-party apps, so if one of them is causing issues, you’ll know. To enter safe mode:
    • Press and hold the Power button until the Power Off prompt appears.
    • Touch and hold Power off until you see the Reboot to safe mode prompt.
    • Tap OK to restart your phone in safe mode.

If your issues disappear in safe mode, an app is likely the culprit. Uninstall any recently downloaded apps and see if that resolves it.

  1. Cache clear – Clearing the system cache can resolve some performance issues without a full reset. To wipe cache:
    • Power off your phone.
    • Press and hold the Power + Volume down buttons until the LG logo appears.
    • When the factory data reset screen appears, press Volume down to highlight Wipe cache partition and press the Power button to select it.
  2. Restore a backup – If you’ve previously backed up your LG L90 using LG Bridge, Smart Switch, or another method, you can try restoring that backup to your phone. This will overwrite app data, settings, and files to that earlier backup state, which may resolve your issues.

These alternatives are worth trying before a full hard reset if you want to avoid the nuclear option. But if all else fails, a factory reset is the most surefire way to get your LG L90 back to proper working order.

When Should You Hard Reset Your LG L90?

A hard reset is the last resort when troubleshooting issues with your smartphone. If you’re experiencing any of the following problems and basic troubleshooting steps haven’t helped, a hard reset may be necessary:

  • Very slow performance – If your phone has become extremely sluggish and is taking forever to open apps or perform basic tasks, it may be bogged down by apps, files, and settings. A reset can clear this out and restore snappy performance.
  • Frequent crashing or freezing – When your phone constantly crashes or freezes up while in use, it often indicates corruption in the operating system or a deeper software issue. Resetting can resolve this.
  • Forgotten password or pattern lock – If you’ve forgotten the password, PIN, or pattern lock to get into your phone, a hard reset will get you back in. Keep in mind this will erase all data on the device.
  • Preparing to sell or give away – To protect your private data, you should always perform a hard reset before selling, recycling, donating, or giving your phone to someone else. This ensures none of your personal information can be recovered.

Before trying a hard reset, attempt some basic troubleshooting:

  1. Restart the device. A simple reboot can fix many minor glitches.
  2. Update Android and all apps. Older software can cause performance issues and bugs.
  3. Clear cache and data for misbehaving apps. Go to Settings > Apps and find the problematic app, then tap Storage > Clear Data and Clear Cache.
  4. Remove unused apps and media. Free up storage space for better performance.
  5. Factory reset a specific app. If only one app is giving you trouble, try resetting just that app to its factory defaults rather than the entire phone.

If those steps don’t resolve your issue, then it’s time to try a hard reset. However, there are some important things to do first.

Backup Your Data Before Resetting!

Since a hard reset will wipe all data from your LG L90, it’s critical that you backup anything important first. This includes:

  • Contacts
  • Photos and videos
  • Documents
  • Music
  • Text messages
  • App data (logins, saved games, preferences, etc)

There are a few ways to backup your LG L90 data:

  1. Google Sync – Your LG L90 likely syncs a lot of data to your Google account automatically, including contacts, calendar events, app data, and more. Make sure syncing is enabled by going to Settings > Accounts > Google and verifying everything is checked and up-to-date.
  2. LG Bridge – LG provides a computer program called LG Bridge that can create a full backup of your phone’s data, contacts, media, and even text messages to your PC or Mac. Install LG Bridge, connect your L90, and follow the backup steps.
  3. Manual backup – For certain data, you may need to transfer it off your phone manually:
    • Connect your L90 to a computer and use file explorer to copy over media like photos, videos, and music.
    • For contacts not synced to Google, export a .vcf file from the Contacts app and save it to your computer.
    • Screenshots of important conversations or information can be uploaded to cloud storage or copied to a computer.

With your data safely backed up, you’re ready to reset your LG L90. The process only takes a few minutes.
