I'm trying to un-softbrick my Nexus 7 (2013) WiFi with Nexus Root Toolkit v1.8.0.

Im getting an error,

Code:
checking product...
FAILED

Device product is 'flo'.
Update requires 'grouper'.

I think that I need to set the option to force the image, but the warning of permanent brickification worries me. I know that this is a Nexus 7 (2013) Wifi, so I should be able to use the KOT49H image (or any of the images in the 2013-WiFi section), from the factory images page without concern, right?

I'm not allowd to post links yet, but this is the site with the Google images: developers.google.com/android/nexus/images#razor

I think you might have Nexus 7 (2012) selected instead of Nexus 7 v2, and yes force flashing grouper image to your 2013 will ruin your day.

You want the selection in Wugs to look like this:

, which will flash this: https://dl.google.com/dl/android/aosp/razor-kot49h-factory-ebb4918e.tgz (this image is the factory image for the Nexus 7 2013 WiFi, aka FLO aka razor.)

You DO NOT want the selection in Wugs to look like this:

Thank you for your help!

I can't believe I did that, how embarrassing! The log (below) makes it look like the operation was successful, but the tablet still won't boot. It sits on the Google logo (with an unlocked padlock icon) forever. I tried both Start and Recovery multiple times with 30 mins between just in case.

Any ideas of what to try next?

Booting up your freshly flashed stock device...
 ------------------------------------------------------------------

Wait for your device to finish booting up...

        - It may appear to be boot looping; just wait...

        - It could take 5-10 minutes; please be patient...

When its finally booted back up, please remember
to re-enable USB debugging if you plan on using
the toolkit to perform other operations.

NOTE: If this process was too quick and your device
is still in bootloader mode, then flashing stock may
have failed or been incomplete.  Simply check the
log above: if you notice it skipped steps because it
didn't meet certain requirements, like the bootloader
or baseband version, then consider enabling 'Force Flash'
mode in the toolkits options menu and trying the
 'Flash Stock + Unroot' processs again.  Cheers.

Try the flash stock + unroot again with force (make sure you have the Nexus 7 v2 one selected first) as per his instructions, if it still does not boot, post to Wugs thread, maybe he'll know.

Do you have a custom recovery? TWRP? when I first got my nexus being so unused to not having an SD card I accidentally wiped everything including my system storage everything even the backups. It wouldn't even let me get to recovery it just sat at the logo forever like ur saying. I managed to get it to the bootloader (which was unlocked by the way still) with the key combo, used the volume navigation to get to the recovery option. It booted after a bit to my amazement. Then luckily I had a USB OTG adapter so I downloaded a new ROM put it on the USB Drive, mounted it in TWRP, then was able to flash it and skipped stock and save it from its infinite bootloop. though obviously you should probably use the factory image. Idk this would obviously require an OTG USB adapter.. They are cheap and could get one expedited if need be I suppose.

Just thought I'd mention that cuz I was surprised it worked out for me. And if u managed to get to the custom recovery flash at any point in the past it should work for you too.
