Factory Reset LG Aristo 5 – How to soft, hard & master reset lmk300

The order of troubleshooting on your Aristo 5 should be Soft reset > Safe mode > Factory reset via settings > Hard Reset via the recovery mode.

For network-related issues, you should first try to reset the network settings, before doing a factory data reset.

If your Aristo 5 is stuck on firmware update or boot screen, a factory reset won’t be able to restore your phone. In such a case, we need to flash a stock firmware via Download mode.

In this post, we are going to learn how to soft reset, factory reset & hard reset (via recovery mode when locked out) on LG Aristo 5 –

During a soft reset, we turn off and turn on the phone. This can fix most of the common issues such as app crashes, overheating, lagging, charging problems, no sound, black screen, etc.

To restart your Aristo 5, long-press the power button and tap “Power off and restart”.

If your Aristo 5 is frozen, the power button may not respond.

In such a case, we need to force restart the phone using the volume down & power buttons.

Press & hold the power and volume down keys for 10 seconds or until the phone restarts.

Check if the issue is gone. If not, use the safe mode before resetting your phone.
