Coming from 10.1.3, had TWRP 2.6.0.0 emmc installed, wanted to use a newer recovery to flash 10.2 because I thought it would offer better compatibility(?). Flashed the ovation-6.zip from the CM 11 thread. Now when I try to flash the latest CM 10.2 nightly (20140108) I'm getting assert buildprop errors. Attempting to edit the updater-script then leads to updater binary errors. Attempting to flash an older recovery also reports an assert error. I ended up using the TWRP 2.6.0.0 BOOTFILES version to flash CWM v6036, then flashing CM 10.2 worked as it should. What is the issue here?
