here is the full build number : A715FXXU2ATE8. U2 means binary update 2
I've downloaded this build, tried to flash with odin... now a new error appears: "only official released binaries..." (you sure know this one...) when comin to that recovery flash part. This problem is new to me, since I've already made it to your custom recovery once... Any idea what I've done wrong this time? TY for your help.
