Installing Official sony latest Rom , no drm keys

[sasa94]

hi guys , have a problem.
Some month ago my cousin rooted my xperia z4 tab ( SGP712 ) , after unlocking bootloader , now his kernel is androplus kernel
3.10.84-v31 without backupping the TA partition ( so the drm keys).
After that i seen , more more crash on my device . So i want to install the official stock rom of sony ( the latest , nougat ? ).
But i dont have drm keys anymore.
so these are the question:
1) There is some way i can install official rom ? ( i know that drm keys are lost forever ). ?
2) There is some way i can receive ota ? ( probably not )

Please guys help me.

Hi,
What is your firmware version ?
kernel v31 is very old (latest for MM 6.01 is v42

You can flash stock rom via Flashtool and Xperifirm( 0.9.22.3 not the sony flashtool)
Google it or search in XDA forums
