with wanam installed, the phone is willing to download the OTA, but the actual install failed. maybe it detected the system modification, maybe the system is too dirty to do a upgrade without factory reset. i donno.
with wanam removed, the phone is not willing to start the OTA at all.
maybe I will try mobile odin and install bootloader in another step, as I see people are having good result in sprint note 3. or I will try a factory reset before trying OTA with wanam installed, again.
will post my result here.
