The 5.0.2 Lollipop update to my Nexus 7 2013 2nd gen. has frozen my tablet on the white Google.
'Wipe Cache Partition' tried several times did not help as there seems to be many [maybe around 50] E: failed to mount / cache (Invalid argument) type of lines that are all there the next time I tried to clear the Cache Partition, so I have no idea if the stuff is in fact clearing or not.
'Wipe Data/ Factory Reset' tried several times did not help. Same thing here, like a trusting dummy I failed to backup before this system update since I'd never had a problem before and stand to lose a lot since my last backup... but, I'm not sure if my tablet is formatting to a factory reset or not. Still frozen.
I've yet to find a forum that can help with this problem.
I'd been watching my notification bar indicate I have an OTA system update available for quite a while and before doing enough research I went ahead and downloaded which seemed to have completed fine albeit did see where some folks had been saying the download stopped without completing.
Then the restart to install went well and completed also and on its own began to restart again. I didn't think anything of it...until it froze at the white Google page and that was it. I tried what was in the last post and since February 14 and I cracked the case open and disconnected the battery hoping it would forget it has a problem... and it has not forgotten so far.
This Lollipop update seems to be ruining American's hardware. I've been without my Nexus 7 since the end of February and written an email to
cl-fred@asus.com with no answer as yet. I'd really like to have my tablet back working as I don't have the money to buy another because then what, Google wastes the new one too?
