The phone is new, two days of life, becuse it's just returned from assistance. I have just rooted it and tryed the eXistenZ rom. The bug start after the firt boot with the custom rom but after restore with original fw the situation don't change...

Write down what you exactly do if you flash the stock firmware.

after flashing by CMW the eXistenZ rom, I have falshed with flashtool (like the rom page request) the .67 kernel. At the start the rom was great but after some minutes the XZ shut down and the only thing I can do to wake it is to connect to the charger and power on. After too much death I decide to revert back to stock rom with flashtool.
For flashing the stock rom I have downloaded the ftf of .67 for my region and simply flashed on xperia... nothing strange... I think

UP! Any idea for fix this problem?

So with stock rom it works fine?

It say:

Batt Health Status:
Good, no need to replace it.
...I think it's a software problem but what can cause this bug? I have already tried to restore the phone multiple times, also with flashtool... but nothing.

No it can not be a bug if you have flashed correctly the newest stock.
I think something other is not good but I don't know what.

Nothing. All ok...

Ok, I dont think so that is a software problem when you have tryied it multiple times. Because I think you know it too: after a clean flash with a firmware which not have this bug(reviews by other users), your phone have to work fine..
What I would try too:
1. Check if sim card is good placed.
2. Try with older firmware
3. Restore NAND backup
And if nothing would help I would send it to the repair center..

It's a backup from the hole system.
This backup you can do in CWM/Recovery.

Do you did a TA-Backup?
So you want the Link from us for cm11?

I did the ta backup.
I just want to know if I need to reunlock the device if I wanna install a AOSP-based custom ROM like CM/AOKP.

If you want to try a non-stock based ROM, you must have the bootloader unlocked.
Otherwise your phone won't boot. It's self-explanatory in the ROM's thread

Download ftf,
Put it in the flashtool/firmware folder,
Start flashtool,
Click on symbol left at the top,
Choose flashmode,
Choose the ftf you wanna flash,
Wait for a window to pop up,
Then connect phone in flashmode and wait till flashing is finished.

Don't forget to also download the drivers which you can do easily with windows. Go to C:/FlashTool/drivers and click the icon. Otherwise you won't be able to enter flash mode if you haven't put the drivers in the folders too. http://forum.xda-developers.com/showpost.php?p=45464122&postcount=3

Can you unlock your bootloader? If so, then you could easily root. If you can i suggest you to unlock it.
If not, you must downgrade and get a pre-rooted firmware.

Bravia engine just oversaturates colors and make them look like amoled. No offense but if this is the only reason you should unlock.
Also bravia enginr still works for videos.

You can backup TA partition. But you will however lose warranty. Or use nutz method to update

To downgrade using flashtool you don't need a custom recovery/root

You can tell me why relock bootloader on flashtool if it makes no difference ???

xperia z1 waranty after BL unlock and relock

simple question: did someone send his/her xperia z1 to sony to repair something after he unlocked (and relocked, ta backup etc) this bootloader? can sony notice if the bootloader was unlocked?

If you unlocked the bootloader and didn't relock it, Sony can see the bootloader is open.
If you did TA backup and restore it for close the bootloader, Sony won't see it.

I don't think Sony saves the IMEI. It's just for create the unlock code.
