## Sony Z1 \\ TA \\ DRM Keys \\ I want you to help me with this

Hi there,

I have a Sony Z1.

My friend accomplished bootload, unlock and back TA. Now I have some hacked Sony Z1 with 120fps video app.

I want to sell this smartphone, so I want to restore settings to its deafult Kernel, ROM and stuff. I have the TA partition or DRM keys, not sure what it's named.

How do I do it?

Thanks

Hi

To flash a stock rom simply use EMMA by Sony.

And to restore DRM , TA ( Only if you backed it up before ) and then relock the bootloader, then check this thread http://forum.xda-developers.com/showthread.php?t=2440597

You're done
