Hello, I am new the Xperia world. I purchased a T-Mobile Xperia Z a few days ago (still within return window). I learned today that it is not possible to unlock the boot loader to get custom roms like CM. I went to Sony's site and was able to obtain an unlock code they emailed it to me. Does this still mean I cannot unlock it?
If I can unlock then I will keep the device if not I shall return it and get the C6602 because it is unlockable.
The code will not help. It is still locked. There is no way to unlock it.
However, you can still flash stock based roms. Just not those that require a custom kernel.

Just like ckyy said...you can still root, flash custom ROMs....there are PLENTY of them out there. Just follow the guides that [NUT] put in the "General" section and it will guide you thru flashing ftf files using the Flashtool. All the ROMs I've used have been for the C6603 (I think I read somewhere on XDA that those are the most capatible with the C6606 (T-Mobile Xperias) DO NOT use the ftf's from C6602!!

A relock should be enough,
TA is only for bravia engine.

Download ftf,
Put it in the flashtool/firmware folder,
Start flashtool,
Click on symbol left at the top,
Choose flashmode,
Choose the ftf you wanna flash,
Wait for a window to pop up,
Then connect phone in flashmode and wait till flashing is finished.

Don't forget to also download the drivers which you can do easily with windows. Go to C:/FlashTool/drivers and click the icon. Otherwise you won't be able to enter flash mode if you haven't put the drivers in the folders too. http://forum.xda-developers.com/showpost.php?p=45464122&postcount=3

Can you unlock your bootloader? If so, then you could easily root. If you can i suggest you to unlock it.
If not, you must downgrade and get a pre-rooted firmware.

Bravia engine just oversaturates colors and make them look like amoled. No offense but if this is the only reason you should unlock.
Also bravia enginr still works for videos.

To downgrade using flashtool you don't need a custom recovery/root

In the threads for relocking bootloader for the xperia z there is always mentioned to flash stock kernel before relocking.
Where can I get a stock kernel for 10.4.1.B.0.101 firmware and what are the steps to flash this kernel?
Thx for your help
