Xperia z1 doesn't power off except by hard shut down. - Xperia Z1 Q&A, Help & Troubleshooting

After many try with different Roms, the boot is upside down. I flashed back the original Rom official 5.1.1. Full system wipe and data, not sd card ,and the problems still there. When I power off the phone through os, it power off but 5 seconds later it boot again just Xperia screen, then shut down then then boot again and shut down until no more battery. The only way to stop that is hold volume up and power button for 10 seconds. It works only that way when the device is on and i want to power off. Is there any way to repair the boot without lost internal memory?

Problem fixed!

[Q] Sprint HTC ONE stuck on white boot screen

Hello,
I've just installed this ROM after wiping Cache/Delvik Cache and system wipe.
Now the phone is stuck on the boot screen and I can not get back into recovery to sort it out.
I held down power & vol+ buttons to get into recovery but nothing happens. The Home & Back buttons flash after 3 seconds then nothing happens.
Any thing else I should do to get into recovery ( TWRP)
My friend whop is a member asked this question on the Developers forum and so far no luck.
we have tried the following:
This is suggested by chogardjr: Plug your phone in to charge. Don't use a USB port for power. After you plug it in try the hard reboot again.
PLEASE HELP
Just for the sake of testing... Have him hold power without holding the volume. It should force reboot, not to the bootloader, so he can get a feel for how the reboot works. It can be finicky during a bootloop cause there are processes trying to run in the background. But it should do it if you hold power long enough.
Edit:
Also find out if the charge light comes on when he plus it in.
Tried and no joy.......

I had a similar problem with a bad kernel flash and could not get the device to shut all the way off - thats why the keys are blinking. I plugged it in to a charger, left it like that for a few seconds, then unplugged, held it under a bright light and waited. After a few more seconds, it shut all the way down and I was able to boot to recovery in the usual way (power+down). You may have to try combinations or maybe not. But, you won't get to recovery until the phone shuts all the way down. High light under in the 'eyes', plugging and unplugging, and holding the power button for up to 30 seconds are all known ways to do this, but as was said before a bootloop has processes trying to run, so the machine can be 'confused' and have difficulty shutting down. Hope you are successful...
Thanks. I actually got it going with one of the answers posted for me, by powering it off under a bright light.
Sounds daft, but it works.

[Q] Xperia SP Frozen, blank screen.

Hi there. I was trying to install a custom ROM, I had a PAC Xperia SP rom but it had too much RAM usage (about 50-80 free RAM with every app closed) so I decided to change it, in CWM I formatted each possible partition after that I realised I have no ROM to install on my SD Card so I took my friend's phone and put my SD into his phone while turned off my phone (it asked about rooting while I tried to turn it off I accepted it). Well it didn't turn off and it's stuck right now with blank screen. I can't turn it off (tried each combination Power + Volume up/down/camera). There's a small yellow hole under which there is written "OFF" I tried to touch it with pencil or something with or without the power button pressed but the phone still won't turn off. Right now i'm trying to unscrew the phone and I read about a little cable attached to mainboard which will turn off your phone if you unplug it for 2-3 minutes. So what else can I do guys. Help.
Don't tear it down yet: HOLD the yellow off button UNTILL phone vibrates 3 times!

Okay. The phone didn't do anything while I was just holding down the yellow button but I manage to enter fastboot or flash mode while pressing YELLOW + Vol up / down, but it seems I don't have drivers for Xperia SP, I Installed each driver from Flash Tool and PC Companion Studio but while i'm connecting device in flash mode to flash tools it disconnects after couple seconds saying it doesn't have proper drivers.
Edit : The phone disconnects from Flash mode and acts like a normal phone connected to USB after couple seconds. minutes depends.
Strangely I managed to get into Recover menu and installed ROM I had on my SD, close it.

[Q] Galaxy S3 GT-I9305 Boot loop problem.

Hi all.
So my girlfriends S3 started something weird this morning.
Last night the battery ran flat, so obviously it was put on to charge. The phone was off while charging, but, instead of the constant icon of a battery charging, the icon would come up and disappear, and reappear, and never become fuller.
When we tried to start it up this morning, the Samsung GT-I9305 screen would come on, and then just disappear and reappear, same as the battery icon.
The phone has not been rooted, no custom roms have ever been attempted, it is as stock as the day we opened the box.
First we tried leaving the battery out for about 30 mins, same would still happen.
Then I removed toe sd and sim card, removed the battery, and tried starting with and without the sim card. The sd card has not been put back. Same thing would still happen.
After some searching, I tried getting into recovery mode by pressing and holding power, volume up and the home key. This worked once, where I chose the restart device option first, but since then I cannot get the recovery mode back again.
I read something about a 'safe mode' by pressing power, home and volume down. This gets me to a screen where I am asked if I want to continue, by pressing the volume up key, but no matter what I press, the device just goes back to the GT-I9305 screen looping.
I wonder if maybe trying a different battery would help?
Any other suggestions on how I could factory reset the device?

Moto G stock bootloop - Not mine so really need help!

Hi all
My girlfriend's sister got a Moto G 2014 this past Christmas.
It's unlocked, and I THINK she already got the 5.0 upgrade.
Yesterday she dropped the phone into me as "all of a sudden it stopped working"
The phone is bootloopin. The white Motorola powered by Android screen will come up, it buzzes, and restarts the phone.
The battery ran out by itself,but that made no difference.
Put the phone on the charger, pressed the power button after a while and same thing happened.
Only difference is that now every now and again it also shows the 0% empty battery screen.
Read around here somewhere about getting into the recovery and wiping the cache partition might solve this, but the button combinations I've seen online (pwr+up/dwn or pwr+up) don't seem to be working.
AND to make it worse, she obviously has no receipt for this.
So please... any ideas?
Charging for just a few minutes may not not be enough. You need to charge it for an hour or so then try to boot to recovery.
Charge it for 1-2hrs..then press power+voldown button together.. Hold it for 5 secs and release them together.. Now tell me whether the bootloader opens or not?

Unfortunately, as soon as the phone starts charging it turns itself on and goes into boot loop.
No buttons pressed or anything, as soon as it stars getting charge it's on!

While plugged in, you should be able to hold the power down until the screen goes black, it may take a few seconds.

Nope, no matter the duration of holding the button, it just keeps on bootlooping.
It's not even holding a charge as it starts bootlooping as soon as there's some juice in it.
Never seen anything like it!

Since it is booting or at least trying to, have you tried holding just the volume up or volume down by itself through one of those bootloops. I mean just keep holding the volume button without touching the power button. This is the major fault I can find with a non-removable battery. You can't easily remove the battery, which will fix some common problems.

Volume Up button doesn't stop bootloop.
Volume Down button DOES stop bootloop.
Afterwards:
Power button - Back to bootloop
Power button plus Volume Down button- Back to bootloop
Power button plus Volume Down buttonfor 5 seconds then release - Back to bootloop
No button pressing - Back to bootloop after 15/20 seconds by itself

[help] clarification needed with the different combinations of buttons during boot.

I have an xperia z with unlocked bootloader and recently flashed a customised 5.1.1 rom, observing that the phone was overheating abnormally (60°c with only a few apps running) I thought a wipe and reset would help me, so got into recovery (twrp) wiped data and cache without touching internal.
Once done I dint see it telling me that SuperSU is missing and accidentally skipped it (I already have root) . The phone started rebooting and went blank. I think the only option is to flash stock again but I wanted a clarification on the use of buttons..
Vol+ + power restarts it again to the blank screen.
Vol- + power or vol+ + power to start the phone again lands me to blank screen after logo
Now to turn it off again Im holding all the three buttons, it vibrates once and reboots if I leave , if I still hold it after one vibration, it now vibrates three times and turns off.
Can anyone explain what exactly are these vibes in the last point , is it kind of a reset , can it help me any way in the future? (I'm still a noob, I just follow the instructions and have used a lots of roms on lots of phones)
I'm soooo sorry for making it a long story, its my first question..
Welcome
Because XZ doesn't have removable battery buttons combination is kinda way of pulling battery out. You only hold power button and volume up together, first vibration is rebooting device, and if you hold little more until you feel 3 vibrations it's power off, as you find out your self.
All the Best.

Oh thank you
So I don't have to be further trying to mess with the buttons and just flash a fresh rom. Thanks
