[Q] Chainfire caused reboot loop

Hi there i have rooted my phone with doomlord's latest rootkit for c6603 UK devices (you can tell im a noob), when installng and the opening he chainfire 3 app it asked me to install some graphics drivers and i did, it then restarted and then the loop restarted (turns off after sony logo, doesn't even get to xperia logo, then turns back on). I have tried several fastboot and flash methods but the problems still persists, does anyone know of any recovery or factory reset methods wihtout having access to your xz?
Thanks

1. Hold on boot volum up and power for 12 seconds i think.
Or
2. Charge the phone and see what's happening

charging it goes into a reboot loop then after a few times it displays battery meter...

ive tried flashing with flashtool but it comes up with "For flashtool, Unknown Sources and Debugging must be checked in phone settings", no idea how i gonna do that though, anyway to flash without this on? maybe fastboot?

I assumed you installed chainfire 3D app.
So, if you want to flash with flashtool, you must set your phone in flash mode.
Hold vol - when plugging the usb cable in (with phone powered off).
If you got the loop, plug the USB cable pressing vol - at the moment the phone is off.

And it may warn you about usb debugging, etc but just ignore it and continue anyway. Ive got back from bootloops with this regardless of unknown sources or debugging. Usually even when bootlooping the hard shutdown will work, hold power and volume up untill the phone vibrates three times and turns off. You may feel it vibrate once, ignore and keep holding.
You do need the correct adb drivers installed to use flashtool, the downloaf here at xda i believe includes them you just have to open the drivers folder, open the exe and choose your phone from the list. If you get into flashboot mode (when you hold volume up and plug it into the computer the led should flash once to let younknow its in the right state. Sometimes flashtool will take a long time to prepare the files for flashing amf your phone will start up... Let flashtool finish prepping, then it will come up with a screen telling you to put the phone in flashmode (usually giving the wrong instructions to do so, ignore them) if so, now go ahead and unplug your phone, power it down via the hard shutdown function i mentioned, then hold volume up and plug it back in. If you get the led flash its working, and if it wont then install its because your drivers arent installed properly.
Also i may be wrong, but the chainfire 3d drivers are for older versions of android, dont try to install them again. I did this on another phone that I had upgraded to jellybean and ot softbricked it. Jellybean runs ope GL fine on this phone.

Ive installed official frmware on my phone (through flashing) and now im about to root it again.
Thanks

I have kind of the same problem here, can you please tell me how you solved it?

[Q] Bricked Xperia c6603 that can't shut down

So the thing is, I decided to buy this phone from another person a few days ago while it was still working but it had this one problem where the owner told me about how the phone can't be shutdown unless the battery runs out of power. Any time you shut it down, it simply reboots instead. I thought it was most likely a problem I could fix after flashing, so I decided to buy it.
Using Flashtool I was able to see that if timed pressing the buttons and plugging it into my computer right before the reboot started, I could boot into flashmode. This phone came in the 4.4 KK firmware and the 10.5.1.A.0.292 Generic NCB build, so I flashed an older kernel and rooted it using Towelroot before reflashing the 10.5.1.A.0.292 Generic NCB kernal. After rooting (and testing if root apps can shut it down which didn't work either), with a locked bootloader I installed the XZDualRecovery using the method here because I was finding it so hard to unlock the bootloader and Flashtool wouldn't do it either. It automatically booted into TWRP recovery menu but when I tried to flash a ROM (existenz Ultimate 3.5 to be precise), it simply made the screen go black for a second and took me back to the recovery menu. So figuring it was a bad download, I downloaded a smaller ROM but when I rebooted I accidentally went into PhilZ Touch menu instead. Deciding to do the usual wipe before flashing, here's where I messed up like an idiot. I saw an option along the lines of "Wipe CLEAN for flashing ROM" or something and trusted it so much despite it saying it's gonna wipe the system partition clean as well (I still don't know why I accepted even when warned of that).
So basically now I have a system that boots the SONY splashscreen and then goes black with the back light still on unless the battery runs out. I can't shut it down no matter how long I hold the power button and if I restart, it boots back to the same thing. I have no recovery menu now thanks to my genius idea of wiping the system, and the only thing I can enter is flashmode. So when I try to flash an FTF firmware (I tried every firmware I could get) back into the phone with Flashtool, it would simply say "preparing for flashing" for about a minute before it says "device disconnected" because the phone decides to exit flash mode and boot normally. I have a locked bootloader (with bootloader unlocking allowed), so I can't flash recovery menus. When I try booting by holding the VolumeUp key and plugging it in, it enters flash mode only with the red LED on and I still get the same results on Flashtool.
Was wondering if there were any ways around this that I might have missed before deciding to open the phone and change the hardware? And if it comes to that, what would I need to change (have always been a software guy when it comes to phones)? Any tips and advice would be appreciated.
TLDR: Have a bricked c6603 from wiping the system, that can't shutdown and keeps rebooting and refuses to be flashed.

If you have time before the phone reboots, hold Volume UP and the power key for 15 seconds. The phone will vibrate once at 10 seconds. Keep holding the keys until you feel 3 vibrations. This will hard power down the phone.

^I've tried this and it simply boots back up again.

Hmm. That should definitely shut the device down, not restart it.
Sounds like there could possibly be an issue with your power button. I've heard of issues with the power button after water damage. Have you checked the water ingress indicators under the flaps? If any are red, it points to earlier damage from water.

Seems like you're right, I just checked it and it indeed has a faded red color on it. Do you think if I take the phone apart it the power button could be fixed or should I swap something else inside this from another Xperia?

I experienced this problem
Pls hold down volume When u connect your phone to pc via flashtool,
It will connect in flash mode
After that , just flash 0.230 kernel via flash mode ( kernel not rom )
Then disconnect your phone
Turn it off ( hold power button and volume up till it vibrates 3 times )
Then before it turn on again , hold down the volume down and connect it to pc via usb and this time flash 0.283 Rom ( not kernel )
This worked for me

Unusual Soft Brick

Hey there,
I followed the guide on XDA to root my Xperia SP with the Towelroot app. The guide is here:
http://forum.xda-developers.com/showthread.php?t=2783885
I then rebooted my phone into recovery, and flashed the latest build.
I rebooted the phone and downloaded the latest Cynagonenmod 12.1 nightly build for the Xperia SP. Once downloaded I wiped my phone and installed the ROM using the TWRP recovery that I'd installed before. At that point I powered off the phone whilst I downloaded the Gapps package on my PC.
When I returned to my phone to try and turn it on nothing happens. It won't turn on or even load the splash screen when I press the power button.
When I hold the power button , the phone vibrates and nothing more! The reset button on the back of the phone does nothing either unless the phone is plugged into a PC. Even then, the phone vibrates 3 times but still won't turn on properly.
I have gone through the Flashroot tutorials over the last 3 hours trying to solve this problem but I've had no success.
I have found that if I hold the volume key down and connect the phone to the PC then the green light appears on the bottom bar of the phone for a period of about 40 seconds before turning off again. It then turns back on and repeats the process.
I am unsure what to do next. Sorry for the long post.
Any help is much appreciated!!

Flashtool progresss
Sorry for the bump but if this helps anyone that could potentially help me. Here is what happens when I try to use Flashtools to flash a stock ROM onto the Xperia SP.
EDIT: Don't worry I solved the problem. I instead used the PC Companion tool to recover my phone and it worked a charm!
I realised the mistake I made. I tried to install Cyanogen Mod 12.1 without an unlocked bootloader which is what likely caused the brick.

Maybe the battery is dead or at least not functioning properly.

I even tried disconnect battery and direct power same issue,
So not a battery issue
Thanks for replying

Maybe since the battery is not functioning properly disconnecting and reconnecting won't solve the issue.

[Solved]Bootloop

Hello my name is Bob and this is my first thread, unfortunately its me asking for help so not really a great start.
Getting to the point however, i installed a 3rd party app which allowed me to change the font of my Sony Xperia Z1 after i did this and it reboot my phone it got stuck in a bootloop.
When i power up my phone i get the following occurences Sony Xperia start screen followed by POWERD BY android and it reboots the phone repeating the process.
My phone is ROOTED, my bootloader is LOCKED, i do not have RECOVERY.
C6903, stock rom
Things i can do with the phone;
Plug it in my laptop and have it show %charged
Plug it in my charger and have it show %charged
Go into fastboot*bluelight* by pressing the volume up button and plugging it into my laptop
Shut it down by pressing the power button + volume up
Go into bootloop by pressing the power button
Edit1: I do not care about wiping all date if necessary or possible!
Edit2: Flashtool, usb debugging off
Edit3: Currently using Sony PC Companion to force re-flash stock
Edit4: Finishing using Sony PC Companion software update, updated to version; 14.6.A.1.236-R2D, currently booting up phone*purple start screen*
Edit5: Phone is working, lost root
Any help would be much appreciated!

Well my opinion always when you root your phone install Recovery
Very important for something like this
*.Font Changer app don't work on Xperia Device (maybe because of Sony company)
If you wanna still want to change fonts there is thread about zip fonts to flash it on your device (it's working great)
And if you got bootloop again just flash rom Through flashtool no need to be USB Debugging on ( just enter flashMod and flash Rom)
And it's good to hear you solved the problem
