How to Reset your Nexus 7 (Wi-Fi)

Today I tried to flash an old Nexus 7[2012][Wifi].

I grabbed the latest image from the section "nakasi" for Nexus 7 (Wi-Fi) from: Factory Images for Nexus Devices

Press: <Volume Up\> and <Volumne Down\> and <Power\> at the same time followed by

<Volume Up\> and <Power\> to get an Android lying on the back ready to be flushed.

PRODUCT NAME - grouper
VARIANT grouper
....

Unzip the image 5.1.1 (LMY47V) and call the script to flash all:

$ ./flash-all.sh
...
(bootloader) Bootloader is already unlocked

Note: You might need to add fastboot to your PATH with export PATH=$PATH:$ANDROID_HOME/platform-tools in case you encounter:

./flash-all.sh: line 17: fastboot: command not found

Let's keep our fingers crossed...

after some Minutes looking at four fancy balls spinning around I finally got the "Welcome" screen.

Hooray!
