Locked boot-loader, once you flash this update you cant downgrade (at Present)
Rom has no knox counter ( warranty Bit) or binary counter.
Rom used to downgrades was T310XXUAMF1_T310OXXAMF1_HOME.tar
Another safe way of trying this rom without fear, is flashing it with mobile odin,mobile odin does not flash boot-loaders so you are safe to downgrade etc.
you may find that you WiFi does not work when rom flashed with mobile odin, that means that the older boot loader is not compatible with the new rom.
Once You flash the rom the device will reboot several times, because my previous rom was customized i had to perform a hard reset.
this rom has some kind of KNOX according to superuser
The rom also adds a new entry to download mode AP SWREV: A1
How to root?
download Cf-auto-root from here and flash it via odin then go to google play and install superuser from chainfire, launch it and update normally.
Rom has a watered down version of knox but no common KNOX entrie in download mode.
Q:Can i install a custom recovery is this rom?
