[SOLVED] Black screen on boot after removing KingRoot - Xperia Z1 Q&A, Help & Troubleshooting

Hello all,
A few months ago I rooted my phone using KingRoot, because it was the only thing that I could get working. However, they added some lock screen with ads which kept on messing up after I plugged my charger in. I used Super Sume pro to remove KingRoot and it required me to reboot, but now my screen only turns black after the startup animation.
Also I can't get into recovery mode for some reason.
Help
EDIT: It's the stock rom, C6903

Download stock rom and flash via flashtools

Thanks for your response, but I fixed it with the Sony PC Companion update tool.

[Q] Cant get into fastboot - Sony Xperia Z

Hi all
I unlocked the bootloader, then rooted the phone then flashed a custom ROM. All went well, then for some reason the phone switched off and for a few hours it would not turn on at all. I left it on charge and eventually I could turn it back on.
However since then I have not be able to boot into fastboot made at all. When i first turn the phone on I am clicking the up volume to get into fastboot, but I never get the sony logo, instead it goes straight to the boot image from the rom (the colourful X), and it does not progress any further, I think the ROM was KA revolution.
Anyone have any ideas? I am completely stuck
and I have followed the steps here using the Update service tool from SONY http://forum.xda-developers.com/show....php?t=2216974
the phone detects fine but it tells me I have custom software and it can't be updated.
fixed now... its all good
Sorry for the bump but do you mind telling me how you got it working?

Phone stuck on boot

I've just got my new z3c and rooted my phone using kingroot and having used super sume to remove it and get super su my phone now won't work.
When it boots up as its loading it say Google play service stopped working and then I get a blank screen. I cannot get it to boot into recovery, in safe mode my PC doesn't seem to recognise it either.
Does anyone know if I can or cannot fix this?

New here and am stuck in bootloop...

So hello everybody, i've been scratching me head at this for a while now.
I have a sony xperia z whose micro-usb to usb port is broken and therefore my pc cannot recognize it.
Now, I am not sure if you've seen the phone but it comes with a secondary charger port kind of thing where it can charge through a dock, and thats what im using.
So i decided to root the phone using kingroot. I was following a guide that showed how to root any xperia device using kingroot and then replacing kingroot with superuser: http://forum.xda-developers.com/xperia-z1/general/root-xperia-running-lollipop-lb-ubl-t3123893
While updating the binaries it said installation failed and i tried looking at other guides. I stumbled upon this thread: https://androidmtk.com/replace-kinguser-with-supersu and followed it even after seeing the disclaimer thinking it would be alright. My dumbass thought everything would be fine and it was until it asked to reboot....
now i'm in a bootloop, with no way to connect it to my comp, and recovery mode not working for some reason (unless im doing it wrong, i dont know).
I believe the loop is a soft-brick (is that the term?) and it turns on shows the sony logo then says "powered by android" goes into the loading screen the stops, shuts off and repeats. I am on lollipop and desperately need help. I have a few school assignments due but can't get my mind off this lol.
ty for helping
Can you boot into recovery? Do you even have a recovery installed?
Flash new firmware use flashtool.. Now xperia z have MM rom..oh yeah
Sent from my C6603 using XDA-Developers mobile app
press and hold power and volume down for 10-12 secs till the phone vibrate 3 times.It will be switched off now.Flash a kernel with recovery included only if you have unlocked bootloader else use flashtool to flash stock firmware.
