Only two combinations of keys work:
Pwr + vol + = reset of the phone, after reset it is a short time when Sony logo came up, and purple led flesh once.
Pwr and vol up and down = phone is shutdown

you need to install the rom ... not only the kernel ... once the purple led comes press the volume up key , it'll take you to the recovery . Do a factory reset and then install the rom ..

EMERGENCY Brick!

hi,
any help is hugely appreciated.
I wiped my phone in recovery with the option to wipe for new custom rom, this worked fine. when i went to install custom rom it failed and then turned itself off. now the phone just gets stuck at the Sony logo. the only way i can turn it off is via the red button in the sim slot.
I am unable to connect to the computer at all, no fastboot. I'm also unable to boot into recovery to restore.
Please help. Hope i haven't ****ed it up beyond fixing
Thanks

Flash a stock ftf with flashtool (in flashmode). You should definitely get into flashmode and fastboot, otherwise there is a problem with your computer.

Funny, I didn't even know there was a red button Holding Volume Up + Power for a few seconds always worked for me, no matter in which state the phone was.

Hi all,
I've exactely the same problem !!!
My phone stuck to Sony logo, and not reconyze on my 3 PC.... before that, usb connexion work fine on all PC, but now.... nothing
I've just POWER + and VOL+ (its power off the phone), i've no led color light
I've try flashboot, but not detect my phone
i've try to install :
flashtool-0.9.16.1-windows (not detected)
Flashtool-drivers-1.5-20140318 (my computer doesnt not see my phone)
Xperia_Z1_Compact_driver (my computer doesnt not see my phone too)

I'm lost... I need your help XDA members ! just U can help me
PS : the red button is in the SIM slot, but i think is same POWER + (VOL+).... its power off the phone

Because you're doing it wrong. Vol+ enters fastboot mode, you have to press Vol- to enter flashmode. Then use Flashtool to restore the firmware.

oI flashed cwm over to my root, bootloader is unlocked and everything. but when I go into recovery mode I get a black screen with nothing on it, and no touch funtion or anything . I thoughght it was bricked until I held the power button for 10 seconds and my computer registered it as being disconnected through usb and the charge light came on . I then flashed twrp over and still, nothing in recovery mode . just a black screen with my computer registering usb input. I don't know what to do. I had to restart it many times pressing the volume down button, holding down power button ect. before it would boot normally but the recoverymode leads to nothing
