what device blank means what..??

CWM is for flashing ROMs. You don't install it, once you've unlocked your bootloader and downloaded your sdk's etc, set up fastboot on your PC to boot custom kernels which contain cwm.
Your phone won't be blank, just user data(not sdcard)will be wiped. Follow the instructions on the SE site, or here.

How to install latest Recovery?
Hi guys. I have just one simply question. I just unlock my bootloader at my ARC S with installed latest Android 4.0.3 4.1.A.0.562. My question is:
How can I install CWM Recovery on it?? I'm asking because all of these tips were written for Android in version 2.3 and I don't want to brick my phone during using wrong guide.
If it's not a problem redirect me to proper Guide and tools.
Thanks

Like I mentioned, CWM isn't installed, as such. No matter what version of android you're running, if you've unlocked the bootloader then, using fastboot, you can boot a kernel that contains CWM.

[Q]lt15i 4.1b LCK BL help

Hi all.
So I have an lt15i with rooted
4.1.b/ 4.0.4 locked bootloader.
The provider is rogers Canada.
As far as I know this provider has made it impossible for me to unlock
My bootloader. But I have also been reading that I just need recovery mode to unlock it. Thanks to the new cwm installer I can now get recovery and have backed up and flashed a ui mod.
So what I am asking is under these circumstances can I unlock my bootloader?.
If so how would I go about trying without bricking or loosing cwm backup?
Sent from my LT15i using XDA

Well I think so that you can't unlock your boot loader ! And so if you do,you can install any kernel to retain Cwm backup or install from auto installer again!

Ok. What I'm mainly asking is I have a locked BL and most methods I have seen to unlock BL needs recovery mode. Normally I cannot enter recovery but the cwm auto install allows me to enter recovery now. So basically what else does unlocking the BL need beside recovery mode?

Bump..
Any thoughts. I don't wanna go into trying it blind.

Strictly speaking it's the other way round, you need your bootloader unlocked to enter recovery. Recovery lets you flash roms, not kernels, and to unlock you either use the Sony site(official) or testpoint(unofficial).

I believe it is flash mode that allows you to flash roms. And recovery(blue light) allows BL unlock then I can flash kernels.
I can both get into flash mode and have 4.0.4 rooted witch I flashed.
But normally booting with vol down does nothing but after cwm install I can boot holding gold down to enter recovery where cwm sits and am able to flash zips and update.zips.
Now so far this seems I can flash an update zip to unlock my bootloader. I am wondering if thia will brixk the device because I am tricking it because in my service menu it says BL unlock no.
If no one has a clue I will try it out.

[Q] how to install cwm recovery on xperia M

I'm still beeing too noob. I've been reading a lot,(thanks to Antrikos48) to but. I am trying to install cmw recovery. I want to backup may entrire phone to my pc. I went through google play and found cwm manager and cwm theter. I read that is necesseray to unlock bootloader before installing cmw. There are some different version of cmw. I'need some help.I'm really lost
I'm sorry about my english
I've read RECOVERY][CWM][2013-10-19][SS] Stock kernel with CWM 6.0.4.4 [Unlocked BL], as well.
Wperima C1905
rooted

May have to hold that thought for a while until the XPERIA M development matures.
I believe(and welcome corrections) that CWM recovery can only be installed on a modified Kernel and not on the stock Kernel.
-----------------------------------------
[update]
See corrected information by @alvinhochun
-----------------------------------------
I did check to see if I could load CWM recovery via flashtool and it was not available/supported.
I suggest Titanium Backup given you have root access.
This means with a LOCKED bootloader you only have to recover Titanium Backup after a SEUS/PC companion restore of the original ROM.
Would mean restoring your mods after the restore such as deleting bloatware from /system/app and etc.

I've published CWM for unlocked bootloader here: http://forum.xda-developers.com/showthread.php?t=2480556
For locked bootloader, there isn't currently one.

That's not exactly true, stock kernel can run CWM. The thing that needs to be changed is the ramdisk. Since the Xperia M does not have a recovery partition it needs a so-called "two-staged boot" to choose between Android and recovery.
Locked bootloader will check for a signature before booting, and will (or at least I think it will) refuse to boot. That's why flashing a modified boot image requires unlocked bootloader, no matter how you flash it.
Just a tip, before unlocking bootloader, remember to back up the TA partition! http://forum.xda-developers.com/showthread.php?t=2292598

Thanks, now I'm understanding a little bit more.I'm waiting for the script to swap the memory. In the meanwhile I'll backup the phone following the TAguide

[Q] Xperia S Unable to Install any Custom Rom

Hey Guys,
New of the forum here. For the past few days, I have been trying to install a custom rom on my Xperia S which I bought in Hong Kong about 2 years ago. I also had it updated to JB .96 version.
I read the forums as much as I could and firstly tried to root the phone. I couldn't determine if I had a locked or unlocked bootloader. I used this rooting guide:
http://forum.xda-developers.com/showthread.php?t=2417672
by doomlord
and then I moved on to installing a recovery which was also following doomlords guide :
http://forum.xda-developers.com/showthread.php?t=2308493&highlight=adb+server
After having done this, I wanted to install PureSlim KitKat on my Xperia S which I found here:
http://forum.xda-developers.com/showthread.php?t=2606528&highlight=flash
But once I got into the recovery of CWM and selected to install the zip file, after installation it says that it will reboot device but it doesn't. I tried to manually start the phone but it couldn't start up. I can only get it to go into flashmode and thus I ended up flashing a ftf which I found here:
http://forum.xda-developers.com/showthread.php?t=2422053
Afterwards, I am back to square one and I repeated the steps to reroot the device and then I installed recovery again and then tried another rom, this time I tried LeopardRom which also resulted in the same problem of not booting.
I also use Galaxy S2 and have custom rom on that but I didn't expect it to be that much different for xperia S. I am willing to follow steps to resolve the issue here.
-Jazi

you cant install that rom because is for unlocked bootloader and you have locked bootloader, you need unlock the bootloader and install a kitkat kernel. When you finish this you can install this rom
Not all of the bootloaders can be unlock. My bootloader can't be unlock so I use a rom that doesn't need unlocked bootloader. The rom is existenz v1.35

[Q] CWM recovery for Xperia M locked bootloader ?

Hi, guys thanks to xda I was able to root my phone now I can't seem find a working CWM recovery file to flash it in my device. I've not unlocked my bootloader though so please help me flash cwm recovery on my c1904 15.4.A.1.9 firmware locked bootloader thanks in advance.

Sorry, but it's impossible to install cwm if your phones bootloader is locked.

i did flash a cwm recovery for my device using flashify.But it just simply reboots it doesn't go to recovery mod. & please do something.

On Stock 4.1 i heared about a CWM for locked bl, but never tried it. But on 4.3 it isnt working. Look for the thread in general section.
But a "normal" CWM on locked bl isnt possible, as the bootloader only loads a kernel from Sony, and to boot into cwm on our device we need to detect an event to extract the cwm ramdisk instead of the nornal ramdisk, which is only possible with a modified kernel, which requires an unlocked bl to get loaded.
