Tablet N7 won't boot after failed Kit Kat upgrade

hi-

i recently got a notification for the Kit Kat upgrade on my Nexus 7. i tried to apply the upgrade but it failed (see attached image). when it rebooted afterwards, i could see the new Kit Kat splash/loading screen (the green + blue + yellow + red droplets coming together), but it never progress beyond that point (that screen will run until the battery drains).

i'm not quite sure how to recover from this, and the worst part is that i have pictures stored locally on the device that i'd _really_ like to keep (a running diary of a daily picture i'd taken for over 150 consecutive days).

two questions:
1) is there any way to recover my pictures?, and...
2) how can i restore my device (or preferably, upgrade to Kit Kat).

fwiw - Clockworkdmod is installed.

While it's booting, you need to hold down power+vol up+vol down to boot the device into fastboot mode. Hold it until you see Andy lying on his back.

Then you need to select recovery and in there, wipe cache partition and reboot.

That should fix it.
Please hit "Thanks" if this post helped you.

hi iBolski-

i tried your suggestion but the boot sequence still doesn't advance past the four swirling dots. any other ideas?

(what's really important to me is getting my pictures off the device. beyond that, i'm happy to wipe the entire thing clean...)

If you se the boot sequence you allready failed at launching the fastboot mode.

that's precisely what i did, and while in the recovery i wiped the cache partition (and the dalvik cache). when i reboot afterwards, it still won't advance past the point i described.

I once had a similar problem and I had to reflash the stock rom via fastboot. But with this method your photos will be deleted and I donīt know any other.
