I think I have a Samsung Galaxy Tab 4 10.1 (Verizon)
On samsung website it's http://www.samsung.com/us/support/owners/product/SM-T537VYKAVZW
I went through all the steps and did a:
adb sideload cm-10.1-20140216-NIGHTLY-p4vzw.zip
But I got red errors like:
"E:footer is wrong" "E:failed to verify whole-file signature" "E:signature verification failed"
Can someone point me in the right direction? Do I even have the right zip file?
