I rarely use my Nexus 7, but today decided to update it to 4.2.2. I flashed everything from android sdk: bootloader, clockworkmod recovery, franco kernel, system, and userdata. Then I sideloaded the SuperSU zip to root the tablet before my first boot up. Now when it boots up, it asks me to type my password to decrypt the storage. I never set a password on the tablet and the other people that used the tablet in my home as far as I know, did not encrypt the storage. Now, I even wiped/factory reset the device from clockworkmod as well as reflashing system and userdata. Why is this occurring?

Re: [Q] Type password to decrypt storage
Boot your device in the bootloader (fastboot) and type
Code:
fastboot format userdata
Or if this won't work you could format every partition and after formatting it you flash the images again

I woke up with the same problem. Tried to boot into recovery and got the "No Command" message. I ended up having to call Google Customer Care and they are sending me a new tablet for free. I just have to send the defective device back to them within days. May be helpful if you bought you device from the Google Play Store.

Hi guys,
I woke up to the same thing too, but I'm afraid to call customer service because my tablet is unlocked..(but it's running stock android and this issue just showed up the day after I updated it to 4.2.2...
P.S: I bought it from the Play Store as well.
Thanks!

I tried that before and it didn't work. Thanks.

I called up Nexus Support and they had setup for me to send it back to them; however, I fixed it after I got off the phone with them. Very strange bug; If I flash clockworkmod recovery, the tablet will boot into the type password to decrypt storage. The factory data reset on clockworkmod recovery doesn't fix it either. If I flash back to the stock recovery and factory data reset, the tablet works fine. I probably don't even need to factory data reset - it's stock recovery that fixes this. I didn't have the "No Command" message though which the Nexus Support guy thought I would have. So I guess I don't have to send my tablet back after all . I wanted to because it's an 8gb and I probably would of got upgraded to a 16gb since the 8gb model is no longer manufactured, haha.

Download android sdk on your pc, go to platform-tools, open command prompt, boot tablet into the bootloader, type 'fastboot oem lock' to lock the tablet again.

Hm I tried locking the tablet as per your instructions, and it succeeded (at least according to the command prompt), however the unlocked symbol is still there. I called support and they told me they can't RMA is till I relock it...

EDIT:
I followed instructions at another post on XDA to flash back the stock 4.2.2 rom as well as perform another oem lock, however the unlocked symbol is still there on the Google splash screen, not to mention the encryption message is still there.

Re: [Q] Type password to decrypt storage
I just wanted to point out: in my experience, you can't sideload anything before first boot after reflashing userdata.img or doing a wipe from fastboot, because it doesn't initialize the data partition until you take it through a boot cycle into the ROM. This may be the cause of the erroneous encryption message in custom recovery.

If you boot the tablet, and then after boot and proper shutdown go into custom recovery, do you still get the same message?

Was there ever a resolution for this issue? I ran into the same thing today - I turned on my n7 after months of no use, and it asked for a decryption password which I never set.
