I disassembled the device to the point where I could take out the logic board. As I was packing up my seemingly dead phone to ship back to LG TODAY, i decided to give it one more shot. Well, on Saturday night LinusTechTips, a popular tech YouTube channel(You should really check them out, they are great), released a video on how they fixed a dead Graphics Card and PCI-E SSD by heating them up past the melting point of solder and then testing them. I looked it up and found that it was a major issue affecting many people, so I just filed for a warranty and received my new phone today. Other people may just get to the Verizon screen, or even just the LG screen. It would get to the "Optimizing Apps" screen and shut off again. Also, if you really have a dead chip, this trick also won't (always) work.īasically what happened, was on Friday, my phone got stuck in a boot loop. If there is a loose contact on the PCB or the "crack" in the solder is too big, it does not work. It only works if a soldered connection has a crack small enough that heat expansion is enough to gain reconnection. I've done this on many many devices, including graphics cards, smartphone logic boards, PC mainboards etc. If you could locate the actual loose connection you could really re-solder it and have it fixed permanently. It might only be a matter of time until it also breaks. My guess is that the loose solder point is only expanding due to the heat. So 358☏, or 181☌, is not nearly enough to actually re-solder a loose connection. ![]() You have to remember that the melting point for SMD solder is around ~350☌, or 662☏. Of course, only if the loose connection is a soldered connection. Don't use an oven you use for food preparation! Toxic fumes can leave residue in the oven and will be re-released upon reheating over many cycles!Īssuming LG's press release regarding the issue is correct and it is really a loose contact, this "fix" could actually work. Remember that heating a logic board to high temperatures can release toxic fumes. I highly recommend doing this ONLY if you have no other option. I plan on using my grill again, so I just made sure to leave the grill open for 24 hours and I'm going to clean it before I use it next. If you are going to use an oven, PLEASE, make sure it's above 385 degrees Fahrenheit and that you don't plan on using that oven for food ever again, this may release some toxic chemicals etc. This has only been confirmed to work on my phone, but seeing as this SAME issue is affecting thousands of people, It's definitely worth a shot. ![]() I was able to get all of my pictures off of it. After 10 minutes, I took it out, re-assembled my phone and it booted. ![]() I turned on the left and middle burners and left the package with my logic board inside on the right side to the grill so it wasn't receiving direct heat. I then placed this package into a barbecue. I took the logic board and wrapped it in one layer of parchment paper and two layers of tinfoil, shiny side facing in(FYI tinfoil has two sides, shiny and matte). Basically what happened, was on Friday, my phone got stuck in a boot loop.
