Bootloop after flashing FXP AOSP 5.1 (D2303)

Hi everyone
So I have problem with booting into system after flashing FreeXperia AOSP build for eagle.
Steps which I've done
- flashed 18.3.1.C.1.15 ftf with Flashtool
- updated bootloader with EMMA
- flashed system, userdata and boot img files with flashtool
- rebooted
And here it ends - bootloop.
I've also tried flashing AOSP while on 18.0.C.1.13 but it also gives me bootloop.
So what should I do to make Lollipop work?
Also here it is screenshot from EMMA: http://dl-1.va.us.xda-developers.com/3/3/4/6/1/1/4/emma.png?key=tWL6nqDvrsdQwlfyPcaOiw&ts=1433344649

Thanks for answers

As it would appear your bootloader is unlocked then you have 2 options - Manually flash using Flashtool and a .ftf firmware file or relock your bootloader and use PCC

Well I know how to get out of bootloop to stock firmware but I'd like to know how to flash 5.1 custom rom (because IT gives bootloop). Stock is not a problem here Slightly smiling Face

Have you checked XDA and you flashed via Fastboot or something else also have you tried a command prompt to flash

I've posted it on Rom thread but they suggested to write it here as well.
So once again
- I've downloaded FXP AOSP 5.1 zip with 4 img files in it: system.img, userdata.img, recovery.img and boot.img
- flashed ftf file with latest SONY STOCK SW 18.3.1.C.1.15 with flashtool programme
- updated bootloader with EMMA (screen in first post)
- opened fastboot and flashed all 4 img files (recovery is not needed but I flashed it anyway)
- after successful flashing, it gaves bootloop.
PS: sorry for misleading in first post. It should be fastboot in 3rd point Face with stuck-out Tongue Dunno why I sometimes mix them up Face with stuck-out Tongue Sorry once again.

No idea why it isn't working unless the compiling of the img is corrupt or your device just doesn't like to boot

On xda they said that some new phones have changes in GPIO input events. That is why mine and other new M2s are bootlooping.
