I got it from staging 1. But it fails to update even though im at stock. I did notice after the update to 5.6.893 my webtop ver says unavailable if that is what causes the failure
I did not want to go back to stock per those instructions, as I was on 5.6.893 and didn't want to have data wiped. I downloaded the 5.7.893 zip from the OP of that thread, then used Root Explorer to move it to sdcard-ext. Then I booted into stock recovery and installed the 5.7.893 zip. Now About Phone shows 5.7.893.
