Hello there,

I know that it will be noobish for some people here, but for me is a big problem. I have Sony Xperia Z (L36h) C6603 which my wife bought for me as a present some years ago. Following the guides here in the forum I updated to RR rom 7.1.2. Everything was great, just the battery was holding not even full day. So I decided to return back to stock firmware and here is what happened:
I used Flashtool as it was said in one tutorial, I flashed the Commercial and Journalist (10.5.A.0.230), I locked the bootloader through Flashtool and I was waiting for the device to boot. Until now (already 2 weeks) I`m waiting for it to boot connected on the charger, but it shows the waves, the Sony Xperia logo and than black screen. Today I tried to unlock the bootloader with Flashtool, it takes me to the menu where it`s saying to disconnect the device, to power it off (I wait 30 secs after powering it off), to press the volume down and to connect the usb cable. The light on the right side of Sony goes red, than green. And that`s it. The menu how to put my phone in flash mode still stays there and nothing else happens. The same is when I try to flash other firmware with Flashtool. I tried Emma but it shows that the bootloader is locked and it`s sending me to Sony`s website to unlock it, through Emma I saw the IMEI and I got the unlock code (but how when I don`t have OS/FW to input the code?). If you know any chance to flash a stock firmware or any other CM/RR, TWRP in my case please tell me. I will try everything to fix it, because the phone is special for me.
Thanks in advance.

Unlocking failed

I got my IMEI from Emma and requested unlock code from unlockbootloader.sonymobile.com, using fastboot.exe I tried to unlock the bootloader and everything seemed to be fine, but Emma still shows that the device is locked. I`ll post the fastboot.exe output:
C:\Users\ruthless\Desktop>fastboot.exe -i 0x0fce getvar version
version: 0.5
finished. total time: -0.000s

C:\Users\ruthless\Desktop>fastboot.exe -i 0x0fce oem unlock 0x2E24******99A7DE (6 digits replaced with * ;) )
...
OKAY [ 0.192s]
finished. total time: 0.195s
@DooMLoRD need your help ;(
