I have a Lenovo Ideapad A2107-H and I read this guide. I followed the guide step by step to upgrade my Tablet.
On step 6 I got
assert failed: getprop("ro.product.device"),
so I deleted this line in the related script file and tried again.
Afterwards, I tried to reboot my device. It only shows me the Lenovo logo and won't boot into Android.
How can I fix this?
