Fastboot cm11 kernel and then try to boot device.
It's kernel problem...
If that won't do the job, do this:
Flash stock firmware through pc companion, root it and install recovery.
Edit:sorry, my bad - I meant flash stock ftf through flashtool...
Download CM ROM again and flash it.
Make sure flashable zip contains boot.img, that's kernel.
You can drive cm rom on stock kernel, your device will stuck in loop...

He can not do this as he unlocked the boot, instead use flashtool to flash a stock FTF then carry on
root it and install recovery.

cnyoen mod 11 boot loop problem
but right now as i said the loop is not allowing the phone to charge.
when little charged the loop is draining the battery and the mobile is switching off.
due to this i am unable to go into fast boot or repair through pc companion
but iam able to go into cwm recovery.
any help to recover ?

Press and hold both the volume up and power button until the phone vibrates 3 times.
Then you can flash the CM kernel
Inside the update.zip is boot.img file, flash with fastboot using the following
Code:
fastboot flash boot boot.img
Then enter recovery and flash the update.zip
EDIT
If you can enter recovery just flash the update.zip
If you have unlocked the boot it should work

i held the power and volume up button and waited for 3 vibrations.
then tried to flash by pressing vol u p button and then the usb cable into te mobile.
but there is no blue light i only see the red light and after some time the cynogen mod boot loop appears.
pls help .

enter recovery and flash the update.zip
Where did you download it from?

i am trying t enter recovery .
i downloaded the cm mod from : download.cyanogenmod.org/device=honami it s a nightly build

That's not recovery, that's flashmode.
Reboot the phone and repeatedly press the volume up button as its booting to get in recovery
Then flash the update.zip

r u there .. can u suggest anything...

Yes, follow my instructions
Enter recovery and flash the update.zip
Do you know how to get into recovery? I have told you in my last post. You seem to have recovery mixed up with flashmode.
You need recovery.

once i reboot the phone and while pressing the vol up button should i connect to pc ?

No, recovery is on the phone, it has nothing to do with the computer.
Please follow the instructions as I have given them

powered the phone and kept on pressing the vol up .. the red light initially there vanished and the screen is blank. i dint see any activity after i powered on the phone except for the red liht flashed 2 times and the light vanished.

OK, leave the phone on charge for a few hours .
Then try again.
If you cannot enter recovery you need to fastboot the kernel from the update.zip and the enter recovery after that.
If all else fails, just flash a stock FTF using flashtool

how do i know if my phone is charging , becoz yesterday i charged my phone whole night .
but in the morning i still see that it does not get till the boo screen.
is this a hardware problem?

What are you talking about??
He can't use fastboot because he unlocked bootloader!?
That's the exact thing you can do when you unlock bootloader...You can flash custom kernel.
If he use kernel image with recovery he has everything..

Not able to boot into recovery

After a thankfully brief episode with soft bricking my phone, I've managed to install the stock 2.1 ROM on it. Using x8toolbox, I rooted it, then installed CWM recovery. Then also unlocked my bootloader succesfully.
BUT I can't manage to boot into CWM Recovery. If I understand correctly im supposed to press back repeatedly when I see the sony ericsson kernel logo on the screen. I do that, but still the phone goes on to boot normally to my ROM.
What can be the reason behind this??

Because of you have unlocked your device's bootloader then flash a custom kernel.It has built-in recovery so you won't have any problem entering the recovery.
Try to manually install the recovery.....

Phone bricked

Hey guys.. i think i have bricked my phone
I have the c6602 model and have a unlockable bootloader but left it locked. I have rooted it using goroh_kuns method
http://forum.xda-developers.com/showthread.php?t=2186368
then put CWM for locked bootloaders on it using this
http://forum.xda-developers.com/showthread.php?t=2187363
then flashed this stock based kernel ROM through CWM without wiping the old one
http://forum.xda-developers.com/showthread.php?t=2175903
but now my phone starts up, and reboots automatically, resulting in a loop. I can not go into the CWM recovery anymore because you have to do it through pc everytime while your phone is on.
Personally i think its Superuser from the previous rom and SuperSU from the new rom mixing up and resulting in the loop boot
Can somebody help please..?

Did you try to enter to CWM recovery by pressing volume key while booting to see if the recovery is working
yes it does not work, the led becomes blue after holding power + volume up it vibrates thrice x 2 then i continue volume up and the led turns blue but nothing really happens, i think its the download mode?

If you have the blue led working this means that it has the fastboot mod working - press VOLUME UP + PLUG INTO PC(not power)
try to switch off the device then press the VOLUME DOWN button while connecting to pc = flash mod
If you have one of theese working you can always repair your device

[Q] Can't enter recovery mode

Hi,
After updating to 4.2.2 I rooted my Xperia by ibtimes.co.uk/articles/484784/20130630/xperia-z-root-android422-jellybean-locked-bootloader.htm manual. And after successful rooting and installing some root apps I decided to install CWM recovery to backup my system. I installed the recovery following androidteen.com/sony-xperia-z-install-clockworkmod-cwm-recovery-with-locked-bootloader manual. Everything went nice and smooth and I entered the recovery mode (by pressing Vol Up while LED was green during booting) and made a backup (btw is that a nandroid backup?). The problem is that I can enter the recovery only once after "flashing" the phone with CWM. Any combination of volume keys, power key or LED will not let me enter it again later. Can anyone guide me how to enter to recovery mode anytime or fix this problem so I can use my backup if needed?
Thank you in advance!

Hey, i use to have this issue with the Z so i just installed this one http://forum.xda-developers.com/showthread.php?t=2261606 that should always let u into recovery, when the phone vibrates and the led goes green hold up. Yeah a backup is a nandroid backup. If you cant get that to work ill try help out further.
When exiting recovery did you answer the question with 'yes'? If so that's the problem. You have to answer no or have to flash a patch by doomlord.

There is no question when I exit recovery. The only option to exit recovery is reboot now (atleast I guess). What patch are you talking about? Could you provide me some link pls.
Well the dualboot is definitely last resort but I would rather fix this CWM issue :/
Yeah this happened to me also, you need to use the dual recovery instead

I don't see the point of a dual recovery. That recovery itself already contains CWM and add TWRP. What would I need 2 recoveries? There should be a way how to make CWM work somehow. Hmmm :/

Nobody seems to be maintaining the older releases of the recoveries for locked bootloaders. This is a known issue with them on 4.2.2 firmwares.
Just install the dual recovery and use only CWM recovery. You will literally notice no difference.

I've got the same problem.
so... I installed XZ Dual Recovery AND the zip file.... Flashed the Honami port (eXistenZ Ultra V1) and flashed the Dual recovery at the same time ( just as it says to do)
Now i can enter TWRP no problem, but when i push volume up it just sends the LED purple, and stays on the sony logo...
any one else having this problem???
Thanks so much for posting this, worked like a charm!
Hi, I also have some issues with getting into recovery mode. Ive bought this handheld not long ago, and deceided to unlock the bootloader and root it, than flash a custom ROM. Unlocked with code received from Sony, rooted with towelroot. I transferred the .zip to the sd, but somehow Im not able to put the device into recovery mode. The LED doesnt light up when I turn the device on. I push the vol button, but no effect. Tried apps to reboot into recovery mode, but the phone everytime reboots normaly...

Yeah my LED never turns green, it seems to turn a purplish color after the Sony logo comes up.
This is so frustrating, is there a tool similar to odin that I can use to flash back to stock?

Connect your device to the PC, and ADB is gonna be accessible for 2-4 seconds while the logo is loading (bootanimation), by that time you can flash recovery using fastboot flash recovery recovery.img or simply enter bootloader mode by (i think) holding power up + vol up + vol down buttons. After you have access to the recovery, things are gonna be easier as you can flash ROM's, kernels etc etc. (either via ADB or the recovery itself)
Best regards,
James

Thank you Everyone for helping and guiding issue is resolved your help is always appreciated...
how?
How?
same problem here with my P7 L00 , forum should work both ways, would be nice if you could post solution... tks
Most likely the solution from #4.
Also note that you can easily enter bootloader mode by
a.) disconnecting device and powering it off completely
b.) holding down VOL DOWN and connecting device until it boots into bootloader mode
(Similarly, if you hold down VOL UP you can enter recovery.)
In bootloader mode, flash the correct recovery, then you can do the three button update with update.app in the dload folder.

Did you flash the correct stock recovery for the device? Not having the correct recovery might just throw you into the recovery instead of flashing the software. Also, the recovery should be unzipped inside the dload folder (some people forget this).
tks! using TWRP 2.8.7.0 that runs ok on EMUI 3.0 - not original recovery - maybe that s why then I can t get to force download?

When you flash stock recovery, make sure that you're using exact version of the ROM.
Like if you had B609 you should use B609 recovery image and no other!
I made the mistake of using B621 recovery image on a B609, thinking "well it's the same, both are KitKat and both are EMUI 3.0" but NO! I was wrong.
Don't make the same mistake i did.
Let me know if you get stuck

Yes, that is the problem - *only* stock recovery can install stock ROMs and updates! Depending on your base version, you should install the recovery for the BXXX ROM (e.g.: if you are on CWM flashable B609, flash the recovery for B609, etc.).
tks all, I will flash stock recory and post back
follow up: TWRP was the issue, flashed stock recovery and was good to go...running EMUI 3.1 android 5.1 already, tks for all!
