Phone stuck in Sony Xperia screen - can't turn off at all [SOLVED] - Xperia Z3 Q&A, Help & Troubleshooting

I wiped data/cache and formatted /system to install the CM 12 nightly. When I tried flashing it, it said it was for all the D66xx models, but wouldn't install because my device is "leo." I then tried to restart the phone, but missed the chance to enter recovery. Now the phone is stuck in the Sony screen and I can't turn the phone off at all. Holding the power button for over 30 seconds is not working. I am just letting the phone sit until the battery dies to try entering recovery again, but that might take a very long time. What can I do? Do you have any suggestions?
EDIT: All I needed to do was to hold power + vol up for 2 seconds and the phone turned off.

And just an FYI, there is a hard reset button inside where the sim tray is

I can't get bootloader to stay on

So I wiped my data/system/androidsecure in an attempt to load a new ROM - booted into fastboot - and then installed boot.img (b/c I'm on Hboot 1.14)
but now...I'm having a huge issue.
Every time I try to load into recovery...it doesn't work. I've tried pressing power+volume down, but when the bootloader screen shows up, it shows for half a second, then turns off - and the phone promptly tries to restart into a non-existent ROM.
Then, I'm forced to press power for 15 secs to get the hard reset...and right when it shuts off I try to press power+volume down, but then the same stuff happens again.
What should I do? I want to install my damn ROM, but I'm afraid that I've bricked it...
Ok, so I realized that I'm a dumbass.
For future generations, I'll leave this up so they can learn from my stupidity - but here's what I did wrong.
When you want to hard-reset your phone and get into the bootloader, press power+volume down and hold until the screen turns off. Then continue holding volume down until you get to the bootloader. It's ONE continuous action.
My mistake was combining the actions you would do if you were trying to restart a phone and what you would do if your phone was off, which are respectively: Hold power for 15 secs, and hold power+volumedown until you get to the bootloader.
SO, to recap, while Power+volumedown is used to get into the bootloader if your phone is off, it is ALSO used to hardreset->gotobootloader.
If you try to hold only Power - you're not going to be able to get to the bootloader, it'll just hard reset no matter what.

Phone stuck after factory reset

Hello!
I have a rooted XT1032 and as the 5.0 update is around the corner i thought i'd start from scratch so everything would be as smooth as possible. I backed up all my files and I commenced with the factory reset. The problem is that after turning off, my phone wants to enter CWM, but is not able and keeps on trying(i think this is due to the fact that the factory reset deleted some CWM files). I only see Andro for about half a second every 5-6 seconds.
Do you have any idea what i could do?
I tried pressing the power button and power+volume down, but nothing seems to work..
So i was playing with and i pressed the power button for 20 seconds and it came back to it's initial state. CLOSED

Factory reset is broken when rooted...simply flash your stock image

Unusual bootloop - can't access recovery OR fastboot but loops on "optimzing apps"

Unusual bootloop - can't access recovery OR fastboot but loops on "optimzing apps"
I had my US version OpO 64GB working with CM12 for quite a while, rooted and bootloader unlocked with TWRP (possibly 2.8.6) installed, then some months ago I tried upgrading to CM12.1 through CM updater. This failed miserably - The phone started bootlooping on "Optimizing apps n of N" - as soon as it finished optimizing apps, the phone would reboot and start optimizing again. Booting to safe-mode (Power + VolUpDown) also fails in the same way (though optimizing fewer apps).
I tried rebooting to recovery mode holding Power + VolDown but it just gives a quick buzz (vibration motor) at the "1+" screen and reboots. The same thing happens when I try to boot to fastboot mode with Power + VolUp. So I'm completely stuck. All the guides show being able to boot either to fastboot or recovery (soft-brick) or else the screen being completely black/unresponsive (hard-brick). My phone is neither of these!
I got frustrated enough that I've let it sit on the shelf for the past 6 months, but now I'd like to fix this. All help appreciated.

Did you try clearing the cache and doing a factory reset ?

That's impossible for me to do since I can't get to launcher or recovery.
No acess to recovery?? Then better take it to service center... Atleast can u boot to fastboot mode or adb accesible then use oneplus one toolkits

Install oneplus tool kit, while optimising apps it gets dectected by pc, just make it reboot mode & do reset.... Dnt worry this can be fixed, if all these seems messy then take it to service center

while things are loading, have u tried to hold vol up + power for 10 seconds or until the screen turns off and then hold vol down + power button until the oneplus logo?

Yes, just tried it. Same thing as described in my original post. When I hold power+volup the screen goes blank. I switch to power+voldown until the 1+ logo. At that point:
1. If I continue to hold the power+voldown key through the 1+ logo, the screen goes blank briefly, the phone vibrates once and reboots. If I continue to hold the power+voldown key, the vibrate&reboot cycle continues indefinitely
2. If I let go of either the power button, the voldown button, or both at or before the 1+ logo, the phone boots normally and goes to "Android is starting... Optimizing app n of 119). When the optimization finishes, the phone instantly reboots.
It's like the phone recovery is gone or inaccessible. Could this have to do with the phone tampering setting? As I said, I had this phone rooted and bootloader unlocked, working fine with CM12 for some time before trying an in-place upgrade to 12.1. That's when things went south.

Mi Note 3 Boot Loop

Hello,
My phone went into bootloop and I cannot do anything to open it. I cannot connect it to the computer or wipe all data from the phone. I have never done aything on it and the bootloop happened while i was sleeping. Woke up to find that the phone is constantly rebooting. Also the phone does not stay in fast boot mode. I managed to open the recovery mode and select wipe all data but the process interrupts and the phone reboots again. I also think that the power button might have a problem because when i only press the volume down button the device enters fast boot mode. Thanks in any help
Your power button may have been stuck. Try to press it harder or from one end.

I have opened to phone to see that the power button was indeed stuck. Had to jam a piece of paper there to make it stop for now.
Install the Recovery ROM with MiPCSuite.

Hi, I recommend you first of all back up your data if still possible.
Then, reboot into fastboot.
-fastboot erase system
- fastboot erase cache
- fastboot erase userdata
-fastboot erase recovery.
Then clean flash a rom.
