Hi! I'd like to wipe cache after upgrading to 8.1: does anyone knows how to enter in recovery mode?
Thanks in advance.
Google is your best friend.....
first make sure your phone is connected to a power source.
Press the volume up key and the power button simultaneously for about 30 seconds or until the root menu appears.
if you get an android lying on the back with the text no command .... press and hold the power button and press once on volume up now you are in recovery.
wipe cache has been removed .... see also link.
