Bootloop - Xperia SP Q&A, Help & Troubleshooting

hello, just a question. after installing the trinity custom rom, i installed the fullscreen toggle app. aftr that my phone just turn off, im not stuck on the sony logo, my phone shows the sony logo and after that, it shows again. i tried to hold the button at the back but it doesnt turn off the phone and doesnt vibrate.i hold it for 15secs and up but the phone turn off and turn on again after 2 secs. by the way, my phone is charging if i connect it to the charger. i cant connect to the flashtool. how can i fix my phone?
will i let my phone just become low battery for it to turn off and then charge it again? how long will it take for it to become low battery? my phone is heating up because of the on and off thing.please help me.

I had this issue and sent back to Sony under warranty, had notice to say should be back in 24-72 hrs.
If you don't have option to send to Sony try phone store and get them to remove battery and flash stock again....or if feeling brave do your self

Glad you got it sorted.
How did you turn off as your original post said you couldn't, just in case it happens again to me when flashing mods.

i hold on the power button (sleep/wake button) and the off button at the back. i hold them at the same time. after feeling 3 vibrations, release the power button. the device should turn off now. when you feel one vibration. it doesn't turn off the phone. the phone will just boot up again.

isnt there a soft reset button on the back of the phone (you know the button you use a pen to press it).

Hi, I have the same issue and I try this solution but it didn't work for me.
Because I want to try the trinity vengeance rom and I'm scared that if I have a bootloop, I can't turn off my phone.
Sorry for my english ^^

Hi, your problem is solved?
Edit: I found the solution in the other topic in Q/A.
I hold the power button with volume up and the off button at the back.
I wait 3 vibrations and the phone turn off. Thanks to xda community

Thanks to your guides I have found out a full solution for this. I'm come from Trinity...'s rom and have bootloop too.
1. Keep the device connected with PC by USB cable
3. Open and prepare a firmware in Flashtool
4. Flashtool notifies to have your phone connected in flashmode --> It's time to go
5. Press and hold combination of Volume Down + Power + Reset
6. After 3 times vibrating with GREEN Led blinking, have your fingers relaxed and your SP's been in flash mode then :good:
7. Bear in mind that you should be careful for the next time playing with Rom and mods! :laugh:

Flashed Xperia T with DooMKernel - Now Bricked?

Hi Guys,
Flashed v2 of the kernel using flashtool and it seemed to randomly reboot and crash and be quite laggy etc for some reason.
Rebooted the phone a few times and phone seemed to work and went into sleep. Tried to turn phone on and it is acting as if the battery is as flat as a pancake, no lights nothing on the screen and won't turn on.
Have tried to charge it overnight and still nothing.
Only used the phone for 2days so not sure if it has bricked or it is just a coincidence and the phone was faulty?
Xperia T was running Android 4.1.2 Build 9.1.A.0.489 with bootloader unlocked
Thanks

I can't seem to get a response when connecting the phone via USB to the PC.
Tried holding the volume up button whilst connecting the USB and also with the volume down button to no avail.
Any ideas?

No joy unfortunately, just tried this on another PC to rule that issue out as well.
It's looking like i'm going to have to send it back for a repair me thinks?

I know i'm probably clutching at straws, but is there absolutely anything else I could try?
Put it on charge and eave it for 24 hours.
Sometimes this brings it back to life.
I take it you have done the hold power button and volume up button for 30-40 seconds untill it vubrates 3 times and then tried to turn it on.

Yeah, tried that a few times, unfortunately nothing happened no vibrate or anything.
Will try putting it on charge again for 24 hours and then see what happens, had the phone on charge at the plug socket for around 8 hours last night but nothing change, no charging light or anything else.
I will try sending it back to the supplier I got the phone from if it doesn't spring back to life after charging for 24hours , I'm presuming that in the UK it could be just a simple swap?
Depends on the retailer/network. I worked for a UK network for 5 years. Outside of 7 days a device went off for a repair. Cpw do a 28 day exchange, not sure about all networks etc you'd have to check the returns policies.

I think what I should be asking really is that if they insist on a repair, would they go the whole hog to test if it had been flashed with non sony stuff, would that be highly likely or just simply swap the motherboards without question?

I've let the phone charge for a few hours and now when trying to turn on the phone, the notification led now flashes red where as before it would not do anything when trying to turn on.
When connecting the phone to PC it still isn't detected.
Ive tried to search for what the notification colours mean but couldn't really find anything.
Is this anything hopeful?

Yes, but leave it on charge untill tomorrow...then try the hard reset and turn on.
Then just keep it on the charger. Red led means low battery

Plugged it back in to the wall charger and it had a solid red light for around 5mins which I haven't had before when trying to charge it.
Will leave it plugged in now till tomorrow.
Thanks for your help so far
From my experience the warranty states if you modify the software it voids the warranty. If it's bricked it could be a pcc brick, a friends XT died that way.
So an engineer may just say it's faulty and exchange it. Hard to say but from what you've said it may come back on now it's charging.

Hi Greg,
Left the phone on charge over night and have tried connecting the phone to PC and managed to get some kind of response when holding either the volume up button or volume down button and connecting to PC and detects the phone as a USB input device for just a second or so, the phone will then have a red LED light again after this.
I connected the phone to PC so I could monitor anything that happened easier and noticed that every now and then the red light will come on for a few seconds and then go off again.
Could I possibly have not left the phone on charge long enough at the plug socket?
Hi,
I had the same problem. When the light turns red wait until the light goes out. Make sure you have flashtool open and make sure you only flash the kernel. Now when the red light goes out hold volume down and plug in the usb cabel connecting to your pc, a green light wil appear. Now really fast flash only the kernel. The phone will go into a bootloop once and goes out again. Now put on the homecharger and wait untill it is about 50 percent. Now put the phone on and everything works as before.

Can I flash with any stock Kernel that is made for the Xperia Tor does it need to be a particular one that will match the firmware that is on the phone?

flash the stock kernel for your FW.
Load the FW into flashtool and exclude everything except kernel.

There doesn't seem to be a Build 9.1.A.0.489 (phone had android 4.1.2 and phone is factory unlocked) in the Kernal section in your thread unless I am missing the point?
Downloaded the stock kernel that was in the DooMKernal thread you posted but that doesn't seem to be compatible with flashtool as it is in img and elf files
Sorry for acting dumb.

XZ not booting: Red LED and 3 short vibrartions, then reboots

My XZ appears to be not booting for some reason.
When I try to power up the device, the LED indicator turns red, the phone vibrates shortly for three times and switches back off.
I tried to have a little research on what the different colours of LED means on the XZ and what this three short vibrations mean but could not find much.
Any thoughts?
The battery is empty,connect it to wall charger.

But... It had 73% when I switched it off, it cannot be dead.
Moreover, even when I try to plug it to the wall, it does the exact same thing again anyway, just tried anyhow.

Nope, the screen doesn't even light up, just the LED indicator going red first, 3 seconds nothing, 3 vibrations, reboots, repeats.

Keep pressing volume up + power for 15 sec and try again.
Or
Use pc companion to repair your phone.

I'm beginning to think the power button is not responding actually.
It does nothing on press and the only way I can get the LED to go red and give me the three vibrations is to plug the phone to the wall.
Odd. It was just on the desk, unplugged, switched on when this happened, the screen didn't respond for touches a moment, so I thought I'd give it a restart, then it didn't switch on again.

The phone just booted, as if nothing happened.
I'll see if I can somehow replicate the problem.

I found something like this in another thread posted by someone, by my understanding, tried to flash a Note 2 ROM on his/her XZ.

turn your phone completely off (hold vol-up + power until you get 3 vibrations) then hold down volume down, and insert the usb cable, this will put the device into flash mode, then use EMMA, FlashTool, or PC Companion to restore to stock.
The red light issue that you are seeing sounds like one of 2 issues, the red light shines like that when the battery is flat and needs to be charged before it can boot, or if you flash an unsigned kernel when the bootloader is locked.

The volume up button seems to work fine though.
Funny thing, though, is my bootloader has been unlocked since the day I got the device. I just don't get what may have caused this. It's back to normal now, mind you, yet still is worrying about stability of my device.

Froze at install screen

Just recently flashed trickdroid, got through the entire install then it froze after it was complete. My device says it has been installed and ready for use but hitting next does nothing.....tried holding power with power down and up (just for fun), phone still will not reboot...any suggestions would be helpful... dont really want to wait for my phone to die to use again, was sitting at 80%..

If it was complete then all you need to do is reboot. Hold the power button for 10 seconds, if that doesn't work hold the power button with volume down and boot in to recovery. Also no need to open a thread for it, just ask in the trickdroid thread :highfive:

That's not a joke, presumably HTC put something like a safety so your phone doesn't turn off in your pocket. So in a dim room the hold power button to restart the phone might not work, hence the bright light trick

Power button not working??

My phone started to act really strange today. When i press power/lock button it wont lock it turns off phone immediately. Sometime it just gives powers screen (wher you can turn off,restart or go in airplane mode). Butt its really strange. I can turn off my phone only if i unplug battery.
So the problem is that when i press power/lock button it will restart or wont happend anything.
Im long on this ROM and its not problem with it. I tryed go on stock ROM and same thing happends.
Anyone have some suggestion ?

Try 2 hold 8 seconds on power button, if this phone will reboot - it's software problem. Just flash a new firmware LT6 for ur phone.
If it does not work, try 2 disassemble ur phone, and watch area nearly power button. If it's damaged go 2 service.
My opinion plastic nearly power button area is damaged, or this is firmware trouble in UI.
Nothing happend after 8 sec's

This can be the sudden death of of phone. It happened to also on the stock rom.
Just press the reset button at back for 10 sec.
Then keep the phone idle for about 20 minutes it will start automatically.

i pressed the hard reset key for about 20 sec or so....but their was no vibration or such.but the mobile is heated constantly from the time of the problem occurrence!!
Yes after pressing the reset button for the few second there should be the vibration.
Since its not vibrating u must take it to the service center.
Sorry I was not be of enough help
