How To Fix LG V40 ThinQ Stuck On Boot Logo

Problem:  Hi, I am having trouble with my LG V40 ThinQ, it turned itself off and back on again randomly however it has gotten stuck in the restart displaying the LG logo. I have tried: a soft reset, wiping it for any water damage, plugging it into charge (which causes it vibrate as normal), attempted to open it in both safe and recovery modes with no success. However since trying these last two options my phone keeps sporadically vibrating with singular pulses and I can’t even get it to turn off. Please help me, I’m a student and can’t afford technicians fees or. worst case scenario, a new phone. I have had issues with it being slow and sometimes apps crashing for a few months and have to scan my phone multiple times daily to clear any excess storage to help keep it running smoothly.Thank you for your time.

Solution: The first thing that you will want to do in this particular case is to make sure that the battery of the phone has sufficient charge by following the troubleshooting steps listed below.


  • Clean the charging port of the phone using a can of compressed air. Make sure to remove any dirt or debris stuck in the port.
  • Use a wall charger to fully charge the phone. In case the charging indicator does not appear then try using a different charging cord and wall charger. You should also try charging the phone from a computer USB port or try using a wireless charger.

Once the battery has sufficient charge remove the microSD card of the phone ( if you have one installed) then proceed with the additional steps listed below.

Perform a Soft Reset

The first thing you will need to do whenever your phone becomes unresponsive is to do a soft reset. This will refresh your phone software and will usually fix most minor software glitches. The soft reset is done by pressing and holding the Power button and Volume Down until the device powers off, approximately 8 seconds, then release. When the phone turns on check if it still gets stuck on the boot logo.

Check if the problem occurs in Safe Mode

Sometimes the problem can be caused by an app that you recently downloaded You can check if this is what’s causing the problem by starting the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.

  • With the screen on, press and hold the Power key.
  • In the options menu that displays, press and hold Power off.
  • When prompted to restart in Safe Mode, tap OK.
  • After your device restarts, it displays Safe mode at the bottom of the screen.

If the phone can boot successfully in this mode then the problem could be  caused by an app you downloaded. Find out what app this is and uninstall it.

Wipe the cache partition of the phone

Your phone will store temporary data in a dedicated partition in its storage space which helps the device run apps smoothly. If this data gets corrupted then issues can occur on the device. To make sure that this is not what’s causing the problem you will have to clear the cache partition of the phone.

  • Turn off the device.
  • Press and hold the Power and Volume down buttons.
  • When the LG logo appears, quickly release and then re-hold the Power button while continuing to hold the Volume down button.
  • Use the Volume down button to select Wipe Cache .
  • Press the Power button to confirm.
  • Use the Volume down button to highlight Yes.
  • Allow several minutes for the process to complete.

Check if the phone will now boot normally.

Perform a factory reset

One last troubleshooting step you can perform if the above steps fails to fix the problem is a factory reset. Take note that this will erase your phone data.

  • Turn off the device.
  • Press and hold the Power and Volume down buttons.
  • When the LG logo appears, quickly release and then re-hold the Power button while continuing to hold the Volume down button.
  • ‘Factory data reset’ appears.
  • Use the Volume down button to highlight Yes.
  • Press the Power button to confirm.
  • Erase all user data and restore default settings’ appears.
  • Use the Volume down button to highlight Yes.
  • Press the Power button to reset the device.

If the above steps fails  to fix the problem then this is most likely caused by a faulty hardware component. The best thing you can do right now is to bring the phone to a service center and have it checked.
