Prerequisites
Before we start, make sure your device is an LG G4 (such as model LG-H815). These fixes are specifically for this model, which has a known bootloop issue. Always back up your data if you can before trying these methods, especially the hardware fixes.
Temporary Fix with Hair Dryer or Heat Gun
The first method is a simple one you can do at home using a hair dryer or heat gun. This quick fix works because the problem is often related to the phone’s internal connections. Heating the phone can help those connections work again temporarily.
Turn Off Your LG G4
Start by turning off your phone and removing the battery. This ensures there’s no power running through the phone when you apply heat.
Apply Heat
Using a hair dryer or heat gun, direct heat to the back of the phone, focusing on the area around the camera. Heat for 3-5 minutes. Be careful not to overheat the phone to avoid causing more damage.
The heat helps fix the loose connections inside the phone, which is what often causes the bootloop issue.
Turn Your Phone On
Once you’ve heated the phone, reinsert the battery and turn the phone back on. If it powers up, quickly back up your important data. This fix may only last for a short time.
Freezer Fix to Temporarily Stop LG G4 Boot Loop
If you don’t have a hair dryer, you can try this freezer method. It’s another temporary solution, but it’s been known to help.
Power Off and Remove the Battery
Turn off your phone and take out the battery. Then, put your phone inside a plastic bag to keep it dry in the freezer.
Put It in the Freezer
Place the phone in the freezer for 15-30 minutes. The cold may temporarily fix the internal issue by slightly shrinking the components.
Turn the Phone On
After taking the phone out of the freezer, put the battery back in and try turning it on. If it boots up, make sure to back up your data right away. This fix is not permanent.
Reflowing the Processor with an Iron
This next option is a bit more involved but can be effective. It involves using a regular iron to apply heat to the processor, which can sometimes fix the problem more permanently.
Open the Phone
Start by removing the back cover, battery, and screws to access the motherboard of the phone.
Heat the Processor
Once the phone is open, locate the processor. Use a clothes iron (on a medium setting) to apply heat to the processor for about 5-10 minutes. This can help the soldered connections re-establish themselves.
Reassemble and Test
Allow the motherboard to cool, then put the phone back together. Try turning it on and see if the issue is resolved.
Permanent LG G4 Boot Loop Fix via Motherboard Replacement
If the temporary fixes aren’t cutting it, you might need a new motherboard. This is a more permanent solution but involves replacing part of the phone’s hardware.
Purchase a Replacement Motherboard
You’ll need to buy a replacement motherboard for your LG G4. You can find these on various online marketplaces.
Replace the Old Motherboard
Disassemble the phone as described earlier. Then, swap out the old motherboard with the new one and ensure all the connections are secure.
Reassemble and Power On
Once the phone is back together, turn it on to see if the bootloop issue is gone for good.
The bootloop problem on the LG G4 is a known issue, but it doesn’t have to be the end of your phone. With these fixes, you can at least get your phone working long enough to back up your data or possibly even fix it for good. Whether you go for a quick fix like the freezer method or replacing the motherboard, these steps can help you get your G4 running again.
