do I need to re-unlock my device after returning to stock via flashtool? - Xperia Z Q&A, Help & Troubleshooting

I meant following the unlock instructions from the Sony website.
I want to reinstall cyanogenmod/aokp and use CWM that cm came with this time!
Thanks!

Do you did a TA-Backup?
So you want the Link from us for cm11?

I did the ta backup.
I just want to know if I need to reunlock the device if I wanna install a AOSP-based custom ROM like CM/AOKP.

If you want to try a non-stock based ROM, you must have the bootloader unlocked.
Otherwise your phone won't boot. It's self-explanatory in the ROM's thread

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
