As we all know at present there is no exploit to root while the boot loader is locked and hence do the TA Backup and save the DRM keys. Now, considering the predecessor Z1, many people are of a view wherein if we unlock the bootloader then DRM keys would be lost and some functions like Xreality and etc wont work.
But, on the 4.4.2 Z1 firmware DRM keys are not lost if we unlock the B/L.( Correct me if I am wrong ).
So, The main confusion now is the following.
* Per Some users who have U/L their bootloader, They mentioned that everything is working fine including Xreality and all DRM keys are intact if they check it via *#*#7378423#*#* on phone keypad -> service tests -> verifiy certificates -> media -> Certificates
* Per some users DRM Keys are lost as in Z1
Now, Considering that there is NO ETA as to when a exploit would be discovered to root without u/l boot-loader.What I want to suggest is that probably we can request our friends who have already unlocked the bootloader to check if DRM keys are lost or not and if genuinely all the features like xreality BIONZ are wroking.
I am not sure who we can do that. So, lets please work on this and possibly all of us who are waiting to ROOT this awesome beast put an end to our patience.
