BACKUP YOUR TA BEFORE UNLOCKING YOUR BOOTLOADER!!!
http://forum.xda-developers.com/showthread.php?t=2292598
You can. Backup your data using TWRP (Nandroid Backup). Unlock your bootloader, then restore your backup using TWRP (if youve lost root, you have to root and install twrp again).

TWRP backup should do it.

What do you mean by Nandroid Backup? Is it the usual backup of the entire System?

Also, I want to flash a CyanogenMod . Anyway to transfer my data,apps and contacts there from my stock ROM?

Boot into TWRP and select backup to perform a nandroid backup. Its a backup of the entire system + apps + settings and so on.

Your contacts may be stored on google account. If thats not so you have to export / import your contact. All apps can be transfered by using Titanium Backup. This app allows you to backup all your apps and settings to your SD-Card. After flashing Cyanogenmod just restore your backup with Titanium Backup.

Hi alteristkang,

you would have to wipe before moving to AOKP or AOSP if you want to keep your apps+data you can with titanium backup pro if you are rooted.
How?

now that you asked for the procedure for backing up with TBP, i will assume that you are rooted already. Get the app from market, choose the backup location, run the batch operation (check mark on top right) choose backup apps+data (do not backup system apps as restoring them on custom rom is not advisable). Flash the rom of your choice, install TBP again choose the backup location, restore the apps+data from batch operation.
Edit: just fyi you can also ask the same question in your thread you started, the thread you open is not limited to one question, you will get answers to your question if you continue asking questions instead of creating a new thread.

When I checked there. I saw the option to backup user apps. I just run that right?. and then I should wipe off everything in the CWM to flash a new ROM and then all I have to do is to just restore my apps.. .. Thanks a lot buddy!!!

if you move down further you will also find backup userapps+Data option. i just found the screen shot on google:
Here it is from older version but should be there.
Edit: follow the instructions on how to in the Custon Rom Thread.
backup the user apps + data so that you are able to retain the app user data as well.

[Q] Can i root and restore in "this" way?

Ok, i'm a newbie with techs, really need some help here, so now
Goal :
Install cyanogenmod 10.1 on xperia z c6603
That means i have to unlock bootloader in order to root.
Unlocking bootloader means wiping all data.
I have to use titanium backup pro to backup all apps and data.
Using titanium backup means root -.-
And there's a way to root my device without unlocking the bootloader beforehand, so..
1. Root my device with locked bootloader
2. Using titanium backup to backup all files and transfer it into another SD card
3. Unlock the bootloader once backup is completed (all data wiped)
4. Flash the cyanogenmod rom
5. Restore using titanium backup from the SD card to the phone
Again, i'm a newbie, is these steps gonna work, or there's a lot of error and would fail? Is there any other way? need some help here~
Don't forget to BackUp TA DRM keys for futher stock installations.
1. Root my device with locked bootloader
2. Using titanium backup to backup all files and transfer it into another SD card
3. BackUp TA
4. Unlock the bootloader once backup is completed (all data wiped)
5. Flash the cyanogenmod rom
6. Restore using titanium backup from the SD card to the phone

my current firmware is 253, is there anyway to downgrade to 350 or 434 without wipe all data or getting bootloop like the nfc thing, which wasted me 3 hours to get back on the working 253 via flashtool ==

Untick, (un-check) the wipe sections in flashtool will prevent wipes. Downgrade with flash tool and make sure none of the wipe bits, (at the top right of the main screen) are ticked and you should save all your data.
I used NUT's ROM from this thread to get onto .253 from .453.

Do check out the section on backing up your TA as eryen has said, just in-case you want to go back to pure stock. Read the thread below.

Treat the above threads with respect, you are dealing with critical things here. Full bricks are possible.
I know this sounds over the top too, but when you do flash CM, I would recommend you read the entire thread for CM. It's over 100 pages but I consider it all to be essential knowledge.
CM 10.1 isn't finished yet, it still has a couple of little bugs, but it is pretty damn good. I will play with other ROM's again, but CM will as ever be my default.
Good luck.

Downgrading to 434 without wiping data will end in a loop with updating NFC drivers.
Backup your data with Backup & Restore by Sony. And downgrade with wiping all.

Also, don't forget to flash CM10.1 kernel in fastboot mode before flashing the ROM.

Titanium backup stock JB restore

Hey guys,
I've got a titanium backup of stock JB and would like to restore it to test some things. I have a few worries tho.
1. Will it remove the unlocked bootloader status?
2. I have nandroid backups of several ROMs on my device will it remove them and should I backup those roms with TB too?
3. Will I be able to unlock BL again if it gets locked?
Cheers!
One thing is sure, it won't relock your bootloader,
Sent from my LG-P880 using xda premium
1. No, that won't happen.
2. Why should it do that? Doesn't hurt to copy it to your computer, though
3. obsolete due to the answer to 1.
When you restore system data make sure you leave "exclude system apks" checked

[Q] Can I use the stock backup app on cm11?

I have just installed the cm11 by bagyusz on my sp (it has a locked bootloader). I made a backup of my apps on the stock 4.3. Can I install and restore that backup on cm11? If yes, how?
Thanks in advance.

[Q] Restoring backups from 4.1.2 onto 4.3

Hi, recently I tried to flash a 4.3 ROM onto my C5303 as an upgrade from 4.1.2. I backed up my phone (using Sony's software), and it turned out that I had to restore the backup since my phone got wiped in the process of upgrading. The thing is, whenever I try to restore the backup via PC Companion, I always get an error message and the restore fails.
Is there a way to go about doing this, or are all of my data and settings lost?
Thanks for all the help.
1) downgrade back to 4.1
2)restore
3)root your phone
4)backup your apps and data(sms,calls,wifi) using titanium backup(make sure you use your external sd to backup your stuff because you may format internal memory)
4)update to 4.3 keeping root
5)restore from titanium backup
