Sony Xperia SP (C5303) BootLoop. - Android Q&A, Help & Troubleshooting

Hi guys!
I wanted to install a custom rom to my Sony Xperia SP (C5303) phone. I rooted it with KingRoot and wanted to boot into fastboot with the help of Quick Boot (Reboot) apk from the play store.
I pressed Bootloader button on the app, and since then my phone is in bootloop. If I hold the power button down, nothing happens, not even vibration. I can't remove battery (isn't removable) and can't turn it off. How can I fix this? I didn't even unlocked the bootloader.
Thanks for your answers in advance.

Xperia S totally briked, what to do?

Hello, I have looked a lot around here but didnt find the solution
I was touching "the "android.policy.odex" for a mod and phone rebooted into sony logo all time. With CWM recovery I tried to restore a backup but It failed
Phone still on sony logo, not boot, the only thing I can do is turn it off by pressing power + volume up a few seconds. It turns off but now, what to do?
I have locked bootloader.
If I try to turn on, it remains in sony logo... recovery doesnt work too
THANK YOU VERY MUCH!

First of all you must hold power+volume up keys till you recieve 3 times vibrate ( after first vibrate you continue holding till it happens )
In this time your phone goes off , and then flash a new official ROM by useing a flashtool if you rooted your phone otherwise use SUS or sony pc campanion to repaire your phone.
Attention: After powering off don't power on again because put you back the first situation

Xperia neo mt15i not responsive

Hi,
i have a problem with my xperia neo.
I have locked bootloader, stock ICS rom, no root.
My phone don't boot up.
I tried to restore the phone with SEUS, but nothing changed (the phone can enter in flashboot (back button while connecting to pc)).
I Don't know what to do now. Is there any possibility to unlock the bootloader without powering on the phone?
Thanks

Hey!
'Maybe' something happened to your screen.
Try giving it for repair.
or you can try flashing the ".ftf" file for your mobile.
You can also give it a whack. it worked many times when my speaker stopped working..
please hit ' thanks' if i helped you!
I tried to flash ".ftf" stock ICS, but nothing changed.
I tried to flash stock kernel and ICS. Same result.
The strange thing is that the phone vibrates, when turned on. If I press the power button againe, after few seconds and keep it pushed, the phone vibrates again.
It seems that the phone try to power on, but after 2 or 3 seconds it shuts down again. I tried to change battery, same result.
Does xperia phone have a recovery?
I've read that i can unlock bootloader with Test pins. Then i can try to install a modified recovery (is it possible to install cwm without powering on the phone? only flashmode?). It works with every xperia neo?
I've realized I can enter in flashmode (with back button while connecting to PC) but not in Fastboot mode (menu button).
I'm SIM unlocked.
Yea..u can use testpoint to unlock bootloader...ur supposed to do it without battery..coz u need to ground it via negative pins..
But be very careful while doing so...read evrythin before u start...
Once unlocked..flash a kernel..then Rom..
If u dont wanna take the risk...goto the service centre...
Nd did flashtool show any error??
Did it! Thank you mate!
Unlocked bootloader with testpins, flashed cwm and new rom.
Thanks again.

Phone restarts continuously

Dear devs, I really need your help. After I flashed a pre rooted marshmallow with twrp, it showed android is upgrading as it should. However after completing the upgrade, it reached lockscreen and restarted. It keeps on doing this over and over again, sometimes showing android is upgrading, sometimes not. Other times it reaches lockscreen, other times it doesn't. This continued to happen until my battery died. I cannot turn the phone off, as soon as I connect a charger, it tries to come on. Even when I turn off with power + volume up, it still comes back on without my input. I can't boot into twrp to load my backup, I can't get into flash mode to use flashtool either. I am totally stuck and have run out of ideas. I am not a total noob and have flashed roms before. Hell, I rooted a device with an unlockable boot loader. I also don't think it's a brick or bootloop, because I've fixed a boot loop before. Please guys there's no Sony repair shop in my country so that's not even an option. I am open to any suggestions apart from sending the phone to Sony
This happened with me too. Simply power off your phone from the power off button where the sim card is(small red button press it using a pin or pen) .Then download and ftf of your choice i recommend download android 4.4.2 ftf and flash it as it is simple to root using toolkit and recovery is also easy to install then install existenz mm as its much better than the stock with xperia X features and has the latest twrp recovery. simply follow this guide but download the ftf of android 4.4.2 http://www.xperiablog.net/2015/03/1...peria-lollipop-using-xperifirm-and-flashtool/

Rooted Sony Xperia Z5 Compact stuck in bootloop after updating SuperSU

My rooted Sony Xperia Z5 Compact is stuck in a bootloop after installing an update to SuperSU. I have been able to turn the phone off by holding down power+volume-up, but am unable to get into recovery mode: I've tried to do so manually with power+volume-down, or holding down volume-down while connecting to PC, and using adb which doesn't see the device. Any ideas, or is my phone bricked?

Take out your phones battery. It will shut down your phone completely. After that put the battery back in the phone and boot it up. See if that works
PS: unplug your phone from charger or pc
