Root Achieved on Sony Xperia Z Ahead of Global Launch

The Sony Xperia Z that just hit the stores in France yesterday has been rooted by XDA recognized developer DooMLord. The Sony Xperia Z, a powerful smartphone and Sony’s latest flagship is capable of taking 999 pictures in 68 seconds and it would be really amazing to see how you can take the complete control of the OS while the device is already so powerful. Regarding the root access achieved by DooMLord, he says:

[quote]So once the bootloader is unlocked its generally very easy to root but there were numerous issues where rooting wasn’t working even using insecure kernel

so I used the ramdisk of CF-Auto-Root for the Nexus 4, modified it a bit for working on the Xperia Z and thats it… Root achieved!

I dont not have this device… all of the testing was done remotely (using teamviewer)… many thanks to the user who willing helped out with the testing![/quote]
