I want to know how to safely unlock & relock the bootloader of my Xperia mini St15i. On XDA there is good info for Xperia Arc but nothing specific for Xperia Mini. The SE's official page for unlocking bootloader only explains unlocking. Since i want to know both unlocking & re-locking the bootloader i want to know the methods that devs suggest. I'm familiar with all the pros and cons of the playing with bootloader. I'm just looking for reliable method. Please direct me. Thanks in Advance.

Using Sony Ericssons fastboot is the best i suppose?

Ok. I unlocked the bootloader. Now i'm trying to flash CM7.2.0 FXP054 with THIS tutorial. Can someone explain step 2 and the waring message, Please 
And warning message, this one? : FXP054 - REQURES SEMC 4.0.2.A.0.42 ROM
You need to download SEMC firmware 4.0.2.A.42 cos FXP054 also won't work with higher fw like .58 or .61 or .62

Ok. Now my XMini is CM7.2.0 but there is no market app in this.
I've installed manually market update 3.1.5 and vending.apk but when i enter market it asks for new account , i click Yes, the app exits to homescreen. Pls help me get a suitable market app 
EDIT: Ok. I followed The Arc Method to relock bootloader of my XMini at my own risk and it worked. I suggest this method for relock BUT some users have reported boot loop issues on XDA, so be careful. I initially flashed stock ROM using wotanserver before unlocking. I used seus to update, then unlocked bootloader again, installed Rage V2 Kernel form XDA. All this in just an hour, but have to follow procedures and use firmware specific files(Otherwise phone becomes a demo piece
).
Wow it was a great experience for me. Thought it would be useful for future users. Topic Closed.
