Hello, I need to downgrade 2 Nexus devices to previous Android versions for testing purposes. I have both Nexus 7 first and second generation devices and I have been able to successfully downgrade first generation devices to Android 4.3 but I am completely unable to do the same with the Nexus 7 2013 device.
I am downloading the images and following the instructions at https://developers.google.com/android/nexus/images?hl=en. I have tried using the two different Android 4.3 images available for the Nexus 7 2013 wifi device. Every time I flash de device, there are no errors on the console (copied below) but when the device reboots, it gets to the Android device with a warning sign on it screen and does not boot. I am able to restore to Android 5.1.1 using a different image and following the same steps. Please help! Thank you very much in advance!
