You are confusing bootloader with CWM based recovery.
Unlocked bootloader only means you can install custom kernels not made by Sony.
To have CWM recovery you will need to either, install a stock based custom kernel which already includes the recovery, or root your phone and install recovery.

You can root with DooMLoRD Easy Rooting Toolkit and then install CWM from CWM Recovery 6.0.1.2 for Locked Bootloader.
This CWM recovery has a glitch which won't indicate charging while phone is off. I have fix for Xperia P but it can only be installed if you did not attempt to install that one.
Or
You can flash custom stock based kernel, you can find a few in Xperia P Android Development.
Do you have PC Companion installed?

Start PC Companion repair and wait untill it asks you to turn off the phone and connect it in flash mode (colume down ahile connecting the USB)
At this stage stop PCC and exit it.
Download flashtool and create firmware FTF as expalin here.
This is just to have a backup firmware in case you need it
Try to install my modified CWM for Xepria P. You only need to press volume down once when the notification LED turn on gray.
If you already installed the other CWM I've linked to do not attempt to install this one.

Yes you must install recovery or a kernel that has one built into it to have recovery.
On our Xperia devices it's pressing the volume down key after powering up. Some CWM implementations has LED indication when to press it so one time is enough, other that do not have LED indication you need to press every second or two untill CWM comes up.

Thanks !
Today i learn some basics from u, Thanks very much Time to Sleep

Actually, if you plug the USB cable CWM will prepare to boot too so you can boot CWM before it switch to charger, once it switch to charger you won't be able to start CWM unless you disconnect the USB cable first.

No need for PMs, just quote or mention me in your post and I'll know you replied.
I don't understand exactly what are you trying to do.
To enter CWM Recovery you need to press the volume down key every second or two after powering up the phone and the Sony logo shows up.
To flash firmware with flashtool you need to press volume down while connecting the phone to the USB while the phone is off.
I would advise against flashing abother formware, at least untill you learn a bit more.
Also, before flashing anything start repair your phone with PC Companion, and then when it ask to power off the phone stop and exit, then create firmware FTF file from PCC files as explained in this article to make sure you have the right firmware for your phone in case something bad happen,
Your bootloader is unlocked so PCC and SUS would not flash it, be prepared.

i have used HTC Desire i root that phone and install recovery .. i just download firmware in .zip format and copy to SD Card and goto CWm recorvy menu and click install upadte from .zip file and my firmware install ...
Can i use same method for Sony Xperia P which i have used for my HTC Desire if Yes
Where can i find that files in .zip so i just copy them to internal memory and install firmawre easily !!!

---

Why would you want to install it at all if it's not newer than yours and you don't have any problem?
FTF files can be flashed with flahtool only.
Custom flashable ROM zip files are falshed using CWM Recovery.

learn another tip thanks

Wjen it first came out it came with GB, mine came with ICS,
You can search for FTF that is compatible with your region or a world one, and flash it with flashtool.
Look for 6.1.1.B.1.75 or 6.1.1.B.1.54, .54 has the 8MP flash bug(not all the picture iluminated)
Exclude TA when flashing if it exist in the file.

---

That make me confused some came with ICS some with GingerBread
i think i have internal version.
i am from Pakistan . i think here all phones are internal version some i also saw T-Mobile,AT&T etc in 2nd Hand market but in New all are international versions.
Here is my phone pic attached !!! :highfive:
