Yesterday I installed the Developer preview on my Nexus 7, to see how it was... Today, trying to get back to Android, I got stuck (for around 20 minutes now) on the following:

root@lvandoeduardo:/home/vandoeduardo/Downloads/nakasi-jdq39# ./flash-all.sh...

Thanks in advance!

I just had the same issue, it even got stuck on the same number of KB. Additionally, I could not use the volume buttons to navigate in the bootloader.

I ended up powering off the device by long-pressing the power button, and the device booted succesfully into android.
