Xperia Z2 :: Cannot Turn Off Phone Without It Initiating A Boot Loop All On Its Own
Dec 29, 2014
I can't turn it off without it initiating a boot loop all on its own. Every time I press the power button and select "Power Off", it turns off and then about 5 seconds later the Sony screen comes back on, stays on for a few seconds, turns back off and repeats. I can break the bootloop by holding the power button for about 10 seconds and turning the device back on. The consequence is that every time I turn off my phone, it discharges totally!
Â
My phone is NOT rooted and it hasn't been modified in any way.
Compilation number 23.0.1.A.0.167
Kernel 3.4.0-perf-gd4d661a BuildUser@BuildHost #1
Baseband 8974-AAAAANPZQ-00027-12
Â
The issue appeared after a few months of use, in November. I think it didn't coincide with any software update. It's not a brand new phone so I wouldn't like to  return it as I already have lots of information in there.Â

So my phone got stuck in the infamous bootloop. I am getting a new one shipped to me. I just don't know of my old one is backed up. I don't even think my contacts are. It has an SD card, but I don't think I ever set up a back up for it. Is there any way to back it up now? Sadly it won't stay on long enough to get passed the AT&T screen.

This morning while at work i decided to try another ROM while I had some time. I have been running VRtoxin with no issues as of this morning. I downloaded the latest pure nexus and proceeded to advance wipe everything but storage. I flashed the rom and dynamic gapps. The phone booted up and seemed to be fine until i tried to open a few of the apps i use on a regular basis. When i went to open facebook, hangouts, google plus and some others i would get a notification that unfortunately the app was stopped. I tried rebooting and reinstalling pure nexus and kept getting the same messages. I finally got sick of it and decided to flash my back up i made this morning of VRtoxin. That's when the boot loops started. I have since then mounted system, advance wiped all but storage and tried to flash both VR and pure nexus. Neither will get past boot loop. I have waited 15+ minutes for each.

My Xperia Z2 (Andriod 5.0) went on bootloop after updating apps from play store. I tried both  safe mode and normal boot. But after boot, the system is in serious lag and will reboot itself afterwards. I tend not to wipe all my data.Â

So i have a sprint s6 with 5.1.1 OBE. I have flashed a kernel for root. I found a video online to make RAM more managable and it had to do with earasing some data in the files and reboot. Now my phone is stuck on a boot loop and goes into the "Sprint spark" screen for like 5 min and restarts. Rocovery mode does not work but download mode does. I was thinking of trying to update with smart switch since there is a small update or maybe re flashing the kernel but i dont think that work and the stock roms for OFE arnt online yet.

I had installed a layers theme on my rooted nexus 6p running pure nexus rom. After i rebooted the phone it went into bootloop.
So i got into twrp recovery and factory reset the phone . Flashed the necessary files but it still continued to bootloop. I formatted the internal storage and flashed Chroma Rom but the issue persists.

I have never rooted my phone nor have I flashed a custom ROM before. I have a 32 GB HTC One M9 from Verizon on stock Lollipop Android, and it has been working perfectly until this morning. I woke up to my M9 stuck in a bootloop. It would boot to the HTC logo, stay there for about 10 sec, then go black and constantly restart again (even as I type this). I can access the bootloader, but it seems none of the options work for me! I can't boot to recovery mode or even power off my phone. It just constantly boots again by itself.

Last Friday while documenting a laundry list of problems I noted that the version of Android I was running was the "I" variety of 5.1 (On Nexus 5 - Honeycomb-LMY47I). At that point, anything streaming audio or video would not work. Now today I try the turn off LTE (prefer 3G) and it starts working? Ok. So I went and looked at the version number in About Phone and this time it was on "D" (LMY47D).
Is it possible for a downgrade to be pushed to a phone from google? I have a stock Nexus 5 bought direct from google. I have been sending in "device reports" from the phone whenever something restarted (including the phone itself) or I had an app crash.
So I am left wondering, could Google have pushed a silent downgrade to my phone?

I got my EVO on Saturday morning and have found something quite annoying... twice now, my phone has gotten stuck on the boot screen and started looping.The first re-start was prompted by a software update. The second, I decided to use the battery up completely and started after charging the battery overnight. I found these instructions on how to hard reset the phone http://www.knowyourcell.com/htc/htc-...tc_evo_4g.html but would like to avoid having to do that as I've spent considerable time configuring the phone to be just as I'd like it.Has anyone else experienced this? If so, how did you solve the problem?

My lg g3 is stuck on a boot loop on start up I got this after upgrading to lollipop and didn't even try of flashing custom roms. I flashed it back to kitkat stock rom but this didn't solve the problem. The interesting fact is that the phone boots without any flaws when connected to the official charger but not with other android chargers with lower capacities so i'm really tempted to replace the battery I want to know whether this is happening due to a faulty battery...

Daughter got scammed on a Craigslist Touch Pro CDMA Alltel. It won't boot, just says Touch Pro for a few seconds then buzzes and reboots. It will do it forever.If I understand correctly, there a boot loader, then a rom. To do a non-OEM rom, you need to unlock the bootloader.Figured out how to get into boot loader mode and successfully flashed with latest ROM from HTC. Not clear if I put a new one on or reflashed the same one. No improvement. Now it says RAPH800 SPL-0.40.0000 MicroP-Hermann (etc).
I can't unlock the loader. Tried Raphael_CDMA_HSPL_037 and got an error 262. In fact I tried all the others, ReLocker, Raphael_CDMA_HSPL_025_MFG just for the heck of it with the same error.I'm assuming that if I can unlock it, then put MightyRom or something similar.Would there be some other issue? Like a hardware problem stoping a preboot hardware test? It won't power on to the SPL when the battery *isn't* in place, power supply on. Nor do the boot loop run with no battery. If it's in boot loader mode, you can pull the batter.

So the last few days I've been having a severe issue with my iPhone 4. Basically, it restarted on me out of no where, and now it's just in a continuous boot loop. It flashes the dimmed Apple logo for roughly 8 seconds, goes black, and keeps doing it over and over.Â
I've searched Google and the Apple communities high and low, tried all the solutions, nothing work. I've tried restoring via both DFU and recovery mode, and nothing works. I keep getting Error Code 21 and 3194, and various others.Â
While in recovery mode, with the USB cord and itunes logo, iTunes will detect that it's in recovery and tells me it needs to be restored.
So, I click restore and update. iTunes extracts the software, then goes to the "waiting for phone", and just keeps going into a boot loop again.Â
I've tried TinyUmbrella to see if that can fix the boot loop issues, but it hasn't worked. Tried on several different computers, with different cords, and nothing. It's not a jailbroken device, or water damaged or anything.
I've deleted the gsp Apple jargon in the host file in my Windows>system32>drivers>etc folder, adding the hashtag to it, etc. Nothing is working for me, despite all the people replying to posts/solutions saying it works for them.Â
I was running iOS 7.1.2 perfectly before it had restarted and did the boot loop. It's now currently plugged in, with the connect to itunes screen.
Info:
iPhone 4, iOS 7.1.2

I woke up this morning to find that my phone had restarted itself over night, Thought nothing of it until 15 mins later I came back to it and it was still stuck in start up on the waves. It wont turn off or do anything when any of the buttons are pressed. The notification light is orange (dont know if that means anything).
Â
I have since unplugged it and I am leaving to drain the battery hopefully that will do something...

I own a Google nexus 5 for about 14 months now and today he suddenly died on me, I was browsing the web when suddenly the screen went dark, I put it in a charger and it kept booting up again and again, I couldn't even get in some sort of recovery system because by the time I wanted to select something it booted up again. At home I tried everything using NRT (Nexus Root Toolkit) but it keeps saying my phone isn't in bootloader mode which is obviously.. I don't now if it's a software or hardware problem. It is an international 16 gb nexus 5.

My Nexus 5 device is unable to boot stock or recovery image. It's a locked bootloader, and stock ROM from my wireless carrier. I charged it with a 2 amp capable charger.
Symptoms: preceding the failure , there were strange slowdowns, apps crashing, and inability to charge the battery over the course of a day. When the battery finally died, that was the last I saw my Operating System. Now, when it's plugged in to power, it indicates full charge. If the power button is pressed it will show the Google logo, then cycle back to the battery charged icon. If the power button is held, the battery logo is skipped and Google logo displayed repeatedly. If the down volume button is pressed in addition to power, I get the screen where I can chose the recovery loader, but then the process of Google logo and reboots persist.
If nothing else, I'd like to grab built-in SD card memory contents and strip out a bitcoin key with about $40 on it that I didn't get to back up before it failed.What have I tried so far: basically everything above to generate those symptoms. I also tried opening the back, and pulling one of the top cover and unplugging the battery entirely. No effect.

I have not used my phone in any wrong way. I did not install a custom rom or anything. no root. randomly in my every day normal usage of my phone, it started to restart. and the the problem got worse and worse. for a few minutes, i will be able to use my phone but then my phone will restart and be stuck restarting. most of the times I can't even go into recovery mode. It restarts again when i get to that. I already resetted my phone, and I wiped the partition.
I have a samsung galaxy s6 SM-G920W8 telus/koodo 32 gb. i got the battery replaced by samsung but that didnt work. i noticed that after a few hours, my phone stops restarting when it reaches to 10% battery life.

I got an OTA update notification for 5.1 I downloaded and pressed install. It prompted me for a restart which i did. My phone has a setting which required me to punch in screen lock code everytime my phone restarts. Now, after restarting, it asks me to punch in the screen lock code. After punching in screen lock code, its stuck in boot animation loop ### Read some posts online and they mention " unlocking bootloader before updating. What is bootloader ? How do i check if my boot loader is locked or unlocked?
I tried to boot in recovery mode and it shows me " No command" ... I wiped cache partition through recovery mode- still no luck. It's stuck in boot loop..

Okay I have the sm-G920P, and I used cf autoroot to root, I then installed twrp and the renegade rom. I also installed the unikernel kernel
The phone will start, display splash, Go to the "android is starting" screen, sometimes lets me choose wifi network, sometimes reboots at this point, the farthest I ever get is where it says we are preparing your services, this may take 3-4 mins. But I can never get through it all the way because the device keeps rebooting itself.
I tried flashing back the stock files from sammobile to no avail, I also went to the best buy store and had the samsung guys flash it 2x .... no luck...
I knew I shouldnt have attempted to root this phone.. Where I can find a PIT file for this model?

So I flashed the latest firmware, after being unlocked, then rent back to bootloader, flashed recovery, went to recovery and installed file. Then restarted...now stuck in boot loop. It booted before I went to flash recovery in the new firmware just fine.
Do you need to flash something else when you flash recovery?
it says device is corrupt when I restart, but I was under the impression that screen comes up when bootloader is unlocked, so not sure if it means anything...

So I was on my way back from vacation yesterday, I had made a phone call a few minutes prior, and I noticed my screen wasn't coming on.Tried holding the power button - nothing.Tried charging - nothing.Tried every combo I could find on google, held them for minutes - nothing.Let it charge for an hour or so - nothing.Then randomly it started allowing me to get to the "Google" splash screen, then the screen would go black and become unresponsive again.
It's gotten a little better, but it is extremely random, sometimes I can get into recovery (TWRP), sometimes I can get the phone to charge, and sometimes it will do nothing at all.After getting into recovery a few times, I noticed that my SD card was wiped (only a TWRP folder remains) and it wasn't a few minutes before that - I did not wipe it.It will not boot, and trying to mount via USB doesn't work - it doesn't allow me to copy any files to try and re-flash the OS (stock rooted 6.0.1 with elemental x).Tried ADB push with no luck, it says file system is read-only.
I can un-toggle System / Data etc in TWRP to unmount them, but clicking to mount them does nothing, the box remains unchecked, and trying to do other things, such as start adb sideload, results in a buttload of mount /system errors..Battery is full (when I can get the phone to charge) and is a new OEM battery.Tried charging, not charging, and plugged into a USB port on my PC...does this sound like the internal memory is shot? How I can revive my lil' buddy???

When I went to bed last night my Z3 was working fine. When I woke up, any app I opened closed with the "___________ has stopped" message, so I decided to reset my phone. Now it's stuck in a loop where it will turn on until it gets to the loading page with the blue wave background before turning off and starting this again and again until I hit the little reset square by the microsd with a paperclip.
I've tried connecting it to PC companion and the Mac version (I have a mac at home but can access PCs.) Once it gets to the part where I have to hold the power button and down key while plugging it into the computer, it does nothing and I can't move forward.
I can't seem to put it into flash mode, and I tried installing the EMMA flasher program but it wouldn't recognize that my phone was connected. After more googling seems that maybe unfortunately my phone needs to be in flash mode for this to work.
I haven't modded my phone, haven't installed many apps, and I actually know nothing about phone dealing with/ programming/ booting/ computer language words so some things I am reading online definitely go over my head. I am willing to try though!
My phone will still charge though!
