My daughter’s mobile phone, an LG G3 from 2014, suddenly got stuck in a blue screen of death after boot. The common ways to “fix” an Android phone were not working, so after googling a bit, a few weird threads started to pop suggesting that baking the LG G3 motherboard at 180° C for around 7 minutes as a quick fix for this issues.
After some more research, I found this video (in Spanish) were a technician fixed this problem applying heat to the memory chip with the proper tools and materials. The thing is that this heat could repair microfractures in the soldering of components or something like that, my digital electronic classes from the university were long forgotten.
As it was an “old” phone, two years, and it was broken without any other alternative to fix it, I was happy to try this procedure. Also, my daughter was like “WOW! SERIOUSLY? WE ARE GOING TO TO BAKE THE PHONE?” so following this excellent video that explains how to replace the LG G3 Motherboard, I proceed to disassemble the mobile and remove its motherboard.
I was kind of concerned about the heat of Pyrex to bake the motherboard, so I put it on top of kitchen silicone glove with a rugged pattern as you can see in the picture and it worked pretty well.
My daughter quickly re-assembled the phone after the motherboard cooled for something like 20 minutes and voilà, it has been working without problem for a week. I still suppose it is a temporary fix, but, who knows?
