While in bootloader, I connected a USB cacble and ran this command to erase cache:
#> fastboot flash cache cache.img target reported max download size of 1073741824 bytes erasing 'cache'...
PROBLEM: It has been running for 10 minutes already. The phone's screen still says
cache.img is 14 MB, downloaded from Google.
Should I give up?
About how long does it usually take? A few seconds, a few minutes, a few hours?
