SONY XPERIA Z1C NOT BOOTING SONY/BATTERY LOGO WHEN CHARGED - THATS ALL.

[cpq]

Hello. I got problem with my "new-used" Z1Compact. I get it 2 days ago.
Phone is not starting, only bootlooping with sony and battery logo when charger is plugged.  
There is no reaction for power button.
When i turned phone ON(plugged to power) i can "make a move" but i can only restart it, with power+vol, im getting 3 vibrations, and phone is restarted. (after restart when im trying vol+ or vol- i dont get nothing)
At first i thought it was matter of crashed ROM when somone updated, so i get STOCK for EU, and i plug phone to USB( same screen with sony + battery logo) with flashtool, he detects phone in flashboot and flash mode, so ive flashed my phone with D5503_14.4.A.0.108_Central Europe (1280-7864), but with no efect(i wasnt abble to WIPE in flashtool..).  
Pc companion does not detects him, there is a Windows pip, but program dont recognize Z1C, but if i turn phone in flash mode( with vol-down) he is abble to detect device, like a Sony/Sony Ericsson.
For Windows i'm SONY ADB Interface Device.(ive installed Flashtool Drivers for all Z phones).
So i dont know what i can do to fix my sony. Any advise?  
I'm not a pro in tel-service. Can someone can tell me do why system is not loading ?
 No bootloader? Something wrong with flashing ? No drivers in PC ? When ive briked my sony Z1, i was in same situation, but phone was reacting for power, and i was ablle repir him with PC Companion.

If you have tried a system repair via Pc Companion and tried a manual flash using Flashtool and still have no luck then I fear something is wrong or the firmware you are flashing is from a different variant of the Z1C as there are three

Where is your phone from? - Is it an import of stock EU designed for sale in the EU

Ive tried repair with PC Companion, but as i said, im sony device only when im in flash mode, but when im doing next in Pc Companion, tel is rebooting, and i cant do anything with that..  Telephone is from Norway.

Let me get this right - You are or have tried a system repair?, the phone gets detected in Flashmode but doesn't proceed or it's not been detected in Flashmode? What operating system are you using and have you made sure your flashmode driver is installed?

Im using flashtool, and when i connect it to pc, phone is going to bootloop, when i hold vol+up im in fastboot mode, when i hold vol+down im flash mode, so i flashed my phone with eu rom, but i cant wipe, so that not give any results.. flashmode drivers are installed. Sorry for my english.

Pc Companion is no good, when program detects sony device,  he tell me to unplug and turn on phone.... But i cant do that ;/

[Thommo]

Did you manage to perform a a manual flash? what operating system is your Pc using?

[cpq]

I manage manaula flash.. with roms for central eu and for Norway, beacose phone is from Norway. But it does not help at all.. Still brick, and works only when plugged.

If it's not switching on without power been connected then you have a battery issue or the connection between battery and board is faulty so you would need to either return your device to the place of purchase or contact Xperia care and have your device inspected http://www.sonymobile.com/global-en/support/contact-us/
