[Nexus 7 Q&A, Help & Troubleshooting] 45rpm:
Flashing N7 fails and returns bootloop

My bootloop occurs after initial boot during part where dialogue screen reads Android is starting "Starting Apps"

I have tried Fastboot a dozen times using different img revisions from developers.google.com/android/nexus/images

all producing the same point of failure. Additionally, I've tried WugFresh 2.1.0 which also produced the same point of failure. Some attempts would show a Signature Mismatch on my tablet while others would pass but show this instead.

archive does not contain 'boot.sig'

archive does not contain 'recovery.sig'

archive does not contain 'system.sig'

archive does not contain 'vendor.img'

I also noticed this error FAILED (remote: (InvalidState))

either way the flashing completes and normal restart still fails at this point. Android is starting "Starting Apps"

Below are outputs from my trials. I have ran each more than once with different

USB cables ports even on different OS (Windows - Ubuntu) and command line. I can get into bootloader on my tablet and even into recovery mode and execute wipe commands from there. I cannot set usb debugging mode

as the tablet will not start completely. I did let the process run for over a day until the power ran out thinking a few restarts might set it right but no luck. Any help would be appreciated.
