I've been presented with the following 6 options:
reboot system now
apply update from ADB
apply update from external storage
wipe data/factory reset
wipe cache partition
apply update from cache
Now I have no idea what most of those options with mean, so I tried to reboot the system several times but to no avail.
At this point, I was as desperate to wipe data/factory reset but even that failed.
I've no idea what to do as I cannot afford to have this repaired at the shop and I do not have insurance either. I'm not sure if dropping it recently, and breaking the volume UP has contributed to this. However, I can use the volume DOWN.
