Several users have reported encountering an issue where their LG phones become stuck on the firmware update screen, displaying a “Do not disconnect USB” message. Given the frozen nature of the screen, troubleshooting becomes challenging. Below, we’ve compiled five solutions to address this problem and unfreeze the phone from the firmware update screen.
Solution 1: Soft Reset
To troubleshoot the LG Phone stuck on the firmware update screen, perform a soft reset. Press and hold the volume down and lock buttons simultaneously for a while to force restart the phone. This action should effectively unfreeze the phone from the firmware update screen.
Solution 2: Battery Pull
Remove the battery while the device is connected to a laptop, computer, or wall outlet. Reinsert the battery and power on the phone after a brief period of being unplugged. Look for a battery icon with a red exclamation point.
To access the battery, remove the back cover’s plastic snap. Unscrew the small screws and detach the plastic cover. Unplug the battery terminal from the left-most top corner, where a flat, short cable emerges. Wait about 10 seconds before reinstalling the battery.
Solution 3: Safe Mode Initiate Safe
Mode to start the phone without any third-party apps or programs, using its original default settings. This step aids in identifying and addressing problematic applications causing the LG phone to get stuck on the firmware update screen.
If a specific app is causing issues and hindering the phone’s proper startup, Safe Mode allows you to disable that app without losing unnecessary data. Once disabled, you can access the phone, remove or uninstall the troublesome app, reboot, and attempt the process again.
Solution 4: Drain the Battery
Fully drain the phone’s battery to force a shutdown and remove it from the firmware update screen. Restart the phone after draining the battery and plug in the charger. You should observe the battery charging, and the phone screen should no longer be stuck on the firmware update screen.
Solution 5: Wipe the Cache/Dalvik Cache
Using the Android System Recovery tool, attempt to clear the cache partition on your phone. If you’re unsure how to access the system recovery tool on your specific LG smartphone, refer to Google for guidance. Explore the Advanced menu options under the ClockworkMod Recovery (CWM) tool, select the option to wipe dalvik cache, and confirm if necessary. This step is particularly useful if you recently attempted to flash an updated ROM, as a stuck firmware update screen may indicate the use of an older Dalvik cache.
