I ran in exactly the same issue.Hm. I managed to get recovery to "Apply update". Command 'adb devices' then shows
Code:> adb devices List of devices attached 090a26b7 sideload
I tried sideloading Clamor again, but that doesn't help, even though the result is "Install completed with status 0."
I still cannot get adb shell to work because device is still unauthorized.
Code:> adb devices List of devices attached 090a26b7 unauthorized
I think I probably deleted by computer key from Nexus when I wiped all the storages and need to bring it back in. Is there a way to use Sideload to push my key in somehow so the tablet trusts me again?
Then I can probably do all the other steps to recover from failed repartitioning... :/
The keys are not gone when wiping - you just have to "enable ADB" in advanced menu of the recovery tool when using the shell commands.
You probably did enable ADB the first time when repartitioning because in the instructions it is mentioned in step 2 under EFS/Persist Backup and stayed enabled for the next steps. Otherwise you would have gotten the unauthorized message before.
