When unlocking the bootloader for the tablet Z i xperienced ;) some problems.
So I made a more extensive guide than the one from Sony

You can find it Here

Greetings!

Wow, that's a long guide. Is the main/only reason to unlock the bootloader to install custom roms (can't this be done with just root access?).
I have root, but don't really wish to install custom roms. I don't have the bootloader unlocked, but I know it can be unlocked

why to unlock bootloader?

why to unlock bootloader?

1. u can flash custom ROMs/Kernels
2. u dont need to worry if the new firmware can be rooted or not as with unlocked bootloader u can always ROOT ur device
3. Sony gives sneak-peaks/preview builds of latest OS which requires unlocked bootloaders, as they did with Xperia 2011/2012 line, so who knows may be Sony may give early builds of next android OS

Thank you very much. This tutorial covered all the issues I ran into so I knew what to do.

Btw, the .bat for allowing unsigned drivers doesn't work on Windows 8. A quick google search helped me but maybe you might want to add that to your tutorial for other, less techy users.

I think it would be wise to mention not to forget to backup TA partition with DRM keys before bootloader unlock.

Wish I saw this post earlier. Oh well. :(

if your bootloader can't be unlocked it means that you can root your device, but won't be able to install any custom firmware. But you can install XZDR recovery.

Don't suppose anyone can help please. I am trying to unlock my bootloader. I have successfully connected to my computer by fastboot and everything is recognised and looks to be fine right up until I put the unlock command in and I get this error.

c:\sdk\platform-tools>fastboot devices
CB5A1WYECJ fastboot

c:\sdk\platform-tools>>fastboot -i 0x0fce oem unlock 0xFBCD6A2B26CB8F88
'-i' is not recognized as an internal or external command,
operable program or batch file.

c:\sdk\platform-tools>

its now starting to drive me crazy. Thanks very much in advance

Use Flashtool. It can automatically unlock bootloader. Only unlock code 0xFBCD6A2B26CB8F88 is needed.
