My N5 hung and shut down abruptly. I tried restarting it but it hung repeatedly at the start screen. Frustrated, I tried factory reset but again it hung repeatedly at the 'erasing data' screen.
I did some hunting and found a soltuion. I downloaded SDK & 4.4.2 image and did a fastboot (i dont know what it means but it seems to have helped everyone) Again, nothing happened (I did unlock the bootloader before doing all of this)
Now I tried factory reset again and just after selecting the "recovery mode" option, the "updates installation" screen appeared and this screen wouldnt go away, at all. I tried to go to the bootloader screen again using the volume down+start keys, but it restarted at the "update installation" screen again and didnt progress any further.
Please help me !
