Using a nexus 5 with STOCK 4.4.4 bought 6 months ago.
In the morning, it was working all fine, while it automatically stops working. It refuses to switch ON when not connected to a charger, and when I connect it to a charger, it keeps on re-booting after the screen where it shows "Google".
Yes, I did try entering the bootloader, by pressing the vol down/vol up+vol down+power/ power for 10 secs/vol up+power. None of these combinations work.
Any ideas on what could be the issue and how can I go around solving it?
