Apply Cold

I was coming back from Paris. I had recorded a video interview and used my smartphone to record audio. When I arrived home, my phone started loopbooting. I couldn’t enter «safe mode», not switch it off: no button was effective. I found numerous tricks on forums, Reddit, Youtube, nothing worked… but the solution provided by this guy: https://www.youtube.com/watch?v=puUJ7mfrT5E I put my phone for a while in the freezer fully charged. Then, it switched on miraculously. But immediately run out of battery. I charged it again, took it out, plugged the charger, switched it on… but it switched off and started its loop boot routine. I suspect the charge to warm it too much. Solution: I did the same again, but this time put in between two cold packs – you know, those things you use to relief ankle pain after football/basketball injury. I am currently saving my audio recording to the cloud. (but as soon as I remove the cold, my phone is considered dead).
