Default [Q] Downgrading on locked bootloader

Hi guys!

I have searched the forum and I DO have got a lot of answers. But still I want to get some things clear before I go on.

I just got myself an Xperia Z. It was already updated to 4.3 .569. The phone has a locked bootloader and I found out that it CANīT be unlocked. So there Iīm stuck.

I was first thinking about following this guide: http://forum.xda-developers.com/show....php?t=2590088

But then I got some more questions.

If I downgrade according to that guide... since I get a custom recovery, can I flash any custom ROM that is made for locked bootloader? Do I even have to use the 4.3 .569 used in the thread above or can I just downgrade and root then choose the ROM to my liking?

Thanx for all your help!

Thumbs up Downgrading

Dear friend:
1-the easy way:
2-Flash 4.2.2 with flash tool
3-Root on locked boot loader
4- Install Dual Recovery follow
5- Install 4.3/4.2 Pre-rooted or any other rom of your choice.

Once you've downgraded, rooted and have a custom recovery, you can use any rom you like, as long as it's a stock based rom for locked bootloaders.
You cannot flash anything based on CM/PAC/AOSP/AOKP etc as they require a custom kernel and therefore an unlocked bootloader.

Just as I suspected! Have been away from Xperias for a while so I just needed someone to give me a nudge in the back!

Thanx alot, mates!
