For some custom roms you need to flash kernels via fastboot and for this you need unlocked bootloader.
if bootloader it's locked use Google and search there is official way to unlock but you will lose warranty and drm.

First flash any kernel you want instructions will be given from where you will download like doomkernel it has inbuit recovery. Reboot into recovery choose your rom
Wipe system,chache,dalvik chache install zip from sd card
Dont flash ics rom over gb kernel or gb rom over ics kernel or it will cause bootloop

Considering you already have flashtool and your desired kernel follow this :
1) Plug in your phone in fastboot mode [S-Off, hold menu key and plug in to PC]
2) Place you .img on your desktop
3) Open up flashtool, select fastboot mode and select flash kernel and select it from the desktop
4) Once kernel is flashed un plug your device restart it open up CWM and flash desired ROM.
Hopefully i helped you out

kernel is an .img file so flash it normally as you do flash kernels...

After flashing the kernel you often need to flash Wifi Modules in recovery

You need to unlock your bootloader. Root is not needed at all.

Yes root is not required so tell what exact error you are getting and first confirm that you have adb drivers installed

If you have fastboot which is available in the apktool kit, you can verify bootloader status by putting your phone in fastboot mode (blue led) then open a shell and type "fastboot.exe getvar secure" without quotes. If it says no then you have unlocked bootloader. You can flash a kernel with flashtool or fastboot.exe. I recommend backing up your TA in flashtool prior to doing anything if you haven't already done so...could save you some trouble in the future.

There are a few things you must do
1. You must install flashmode and fastboot drivers
2.you must select xperia play as current device
3. Reboot into fastboot via ADB
4. Once booted into fastboot mode, click on select kernel to flash.

I know it's a pain to do but have you tried returning to stock and starting all over again?I take that flashmode works?That's what I would do if it happened on my phone:good:
EDIT Try disable antivirus
The real question is: have you run flashtool or the command line in "administrator mode"?

Update your version of flashtool uninstall the drivers from device manager. Reinstall never androxide flastool reinstall drivers make sure debugging is enabled. Then you should he good to go. If it don't work that means you need a new micro USB cable..

Also make sure you are using a USB 2.0 port as 3.0 has lots of problems with flashing

Check command which you are typing in cmd. Maybe you wrote something wrong. If you can paste your error after entering this command.

If your device says bootloader unlocked allowed= yes, then I suggest you to use that tool which is explained at the previous link. I unlocked my bootloader using that. Believe me that really works!

To install fastboot drivers you have to be very fast, 2 or 3 times practice is necessary. Going to device manger install your driver so quickly then you can get your phone at fastboot mode easily. You won't get time more than 3 to 4 seconds.....!
I think, you already have fastboot drives downloaded at your PC, thanks!
If the problem again remains, please update your flashtool...! This also may be an issue.

Use this kernel http://forum.xda-developers.com/showthread.php?p=42005739
This is advanced stock kernel which has pre-loaded CWM recovery, when phone reboots you will get led to yellow then press volume + & you can use working recovery!
And then flash latest 6.2.B.1.96 FW..!
But if u want rooted 1.96, don't forget to follow this tutorial...!
