My #oneplus3t died. Did not start, did not charge. Cleaned the usb-c port, still did not charge. (It has a notification #led which remained dark, indicating that nothing was happening.) Nevertheless, I left it charging for >24h with no effect.
TL;DR: 100% dead.
As a wild guess with a completely dead phone, I put it for approx. 10h in the refrigerator (roughly somewhere around 5°C), as some urban legends around this exist.
After getting it out, it started booting and went off after some seconds.
After connection to the pc ( #adb, you know) it booted successfully into #lineageos and I was able to do a backup followed by a factory reset.
The battery stayed at 0% while the phone was on. After the factory reset, it even seems to charge properly.
Question: what did the low temperature do?
