TA-Partition Restored under 6.0 Update

[Cissamannen]

Hey,

So I had one tablet SGP771 that had a broken TA-Partition after unlocking bootloader and enabling My Xperia. After updating the tablet to 6.0 My Xperia asked for login etc, and it now works flawlessly without any issues to activate and deactivate. Is it now maybe a chance for all those who broke their TA-Partition to regain root status if an exploit is found in 6.0 kernel?


Also a sidequestion. I have the SGP712 version of this tablet as well, other one is my GF's after i broke it. But I have root on this, can I update to 6.0 after using AndroPlus kernel without losing root status?

Thanks in advance

The same here

You are my Hero, thank you so much.

I have unlocked the bootloader of my z4 (712) and didn't noticed that the TA and all DRM keys are getting lost on this action ("chief fast finger" strikes back again :crying: )

But then I read your posting and made an attempt. And what should I say; It seems to me that the DRM keys are back again. The Album Widget is working, TrackID works again. For me Emma made it; YMMV of course

Thanks so much:

BTW can someone tell me a way to find out a (nondestructive) way to find out if the keys are really there?

Try toggling the display enhancement options like X-Reality and see if they indeed change the display?

I have checked the service menu in the meantime and found out, that the DRM Key are gone
Service/Security shows:
Blobs: generic error!
HUK: generic error!
OTP_LOCK_STATUS : LOCKED

But I have official Android 6.0 MM now; This more than nothing
