HELP, My phone refuses to boot up.

It started as soon as I received a phone call from my brother and we were in the middle of a conversation when the phone suddenly goes off. I tried to restart it, I even removed the battery and replaced it but when I press the power button I get the initial boot sequence showing the htc logo and then the phone would just go of. I thought that maybe the battery is low but when I plug it to a power outlet it keeps trying to boot but keeps switching off and it just does this over and over.
Please I don't know if anyone has encountered this problem before, I really don't know what to do.

Try a Hard Reset using the device buttons:
1. With the phone off. If it’s frozen or unresponsive, pull then replace the battery.
2. Press and hold the Volume Up and Volume Down buttons and power the phone back on.
3. Continue to hold Volume Up and Volume Down until a factory reset screen appears.
Hope this helps!

Well I just did that but the problem persist. I should note that occasionally it does complete its boot up and I can use the phone but it can go off at any time and once it does this, i cannot get it to completely boot up. Once it attempts a boot up and goes off I cannot even restart it by pressing the power button until I replace the battery or plug it into a power socket or the computer at which point it will just keep booting up and shutting down.

Something far wrong there. Get a replacement device.

Hi, I have got the same problem on my HD7 and I am completely noob to many new words Goldcard, jailbroken, etc. Would you please advise me exactly what you did (i mean flahing procedure) and really appriciate any help.

Well if you have got an O2 HD7, then I would advise you to get one of the O2 ROMS from ansar, download it then press and hold the volume down button when booting up your device, connect the phone to your pc and start the app. More instructions in the HD7 development thread.

There's nothing wrong the phone. Don't hard reset or flash it. It happens from time to time, just give it some time and eventually you will see a battery icon appear. Then after awhile it will boot up.
Again, do not flash or hard reset just be patient. I believe it just needs to drain all the way down as it doesn't have enough power to fully boot.

Not booting up

[Q] Samsung Galaxy Exhibit II 4G (SGH-T679) Can't Boot

My Galaxy Exhibit II 4G is about a year old, rooted and i have CM11 installed. Everything was fine, I had it plugged in (charging) and i was downloading an app (Camscanner) from the Mobogenie store when suddenly the phone shut off and the battery icon appeared with the loading circle in the middle.
This did not stay on for long as the screen would go off and this would again appear. After pulling the battery and removing the charger, then reinserting the battery, the phone would just flash the SAMSUNG logo in this very same manner.
I am unable to get into either recovery or download modes and when i try this combination (VOL UP + VOL DWN) i get:
RAMDUMP MODE
Cause: Force Upload
I have been reading forums for hours and i have found nothing. Is my device bricked? What can I do to recover it? Please, any help would be greatly appreciated :crying:

What happens if you try vol. up + power, or vol. down + power?

Thanks for replying. Nothing happens. It just continues to reboot like I'm not doing anything. The only way I'll get a reaction out of it is with vol up + vol down

It can be tricky. This post may be clear http://forum.xda-developers.com/showpost.php?p=32437850&postcount=6

The link you sent me to sounds similar to my problem, except I wasn't trying to update the firmware. The crash was spontaneous.
However, neither of those methods work. As soon as I put in the battery the SAMSUNG logo appears, then disappears and reappears and it continues like that... Pressing the power button does nothing, whether by itself or with the volume up/down button
I am beginning to panic

What happens when it's connected to power?

Anyway, after many hours of investigation I discovered it was a hardware problem. The power button was stuck and so it forced it to reboot repeatedly. It also explains why it (the power button) was unresponsive. Disassembling the phone and freeing up the power button solved the problem.
P.s. Your build of CM11 is boss

I have same problem with power button. Had to tweak it hard cause it was so sensitive.

It's the first time it's happened to me. Probably because I dropped it so many times

Strange, ...

OK so I'm no expert or anything but maybe my experience with this Model might be able to help you a little bit. I have the same model and it was doing the exact same thing however I haven't rooted it. And I've since corrected the issue on mind particularly it appeared that it was the charge port and/or USB that either had a bad connection or possibly it was boot looped. However with me not rooting the I didn't understand how it could be booted Looped so I started playing around with holding the power button playin with USB things of this nature and what I found was that if I hold the USB to one side either left or right, this allowed me to help a boot farther into it sequence at first to just show the Samsung logo over and over then I could get it to get to the boot sequence about halfway through the boot animation until I finally got to the exhibit screen where displays its model and 4G status. I accomplish this by holding the USB to one side and pushing and holding the power button intermittently throughout the boot. Once I hit the unlock screen unlock the device and I immediately factory data reset it. I'm under the impression that mine was possibly I think that mine was somehow a corrupted bootloader or software still I don't know what caused it to backed up to this day occasionally it'll shut itself down and reboot on me that's why I'm here today I've got all the parts and pieces I need to flash a new rom and hopefully new software the new work over I'll be good to go I also cleaned the USB port made sure that it was still snug to the board all of the good stuff. I don't know if it'll help you but I had the same situation I thought you'd like to know that it was probably not what you were doing with the phone it may just be the software itself with this particular phone see I done nothing that you didn't had the exact same problems. I hope it was somewhat helpful if you haven't gotten it unlocked or re-booted yet. Then maybe just play around with the power sources and power buttons. And see if you can get the same results I did

LG G6 won't boot, loops Lg startup Screen.

Forgive me if this has already been answered, but stick with me here. I am not tech savvy so any replies will be much appreciated, although try to keep them step-by-step. My lg g6 is stuck on the lg screen and loops that, sometimes it after the lg logo appears the tmobile screen pops up but then the screen goes black and everything repeats. I have tried booting the phone into recovery, fastboot etc, but i can't seem to.
-Backstory
The phone originally had water damage, so i replaced the battery. After doing so i realized the phone started up really slow, but once booted everything ran fast as normal. I immediately realized that the microphone and speakers did not work, on top of not being able to make phone calls or record video as it would freeze the screen and then crash the phone. I was also not able to play some types of media like youtube (even though it was able to play youtube before the incident), with it giving me a playback id number. This little sub issue was also stated on (https://forum.xda-developers.com/tmobile-g6/help/audio-media-played-h872-t3793006), but i cannot find anyone else with this problem or solution. But first things first, how do i get out of the loop?
In future regards, thanks for the help.

Honestly, it sounds like your phone is on its last legs. Try factory resetting the phone.
1. Press and hold the Power Button + Volume Down Key on the phone to force a restart.
2. Release the buttons when the screen goes black.
3. Immediately press and hold the Power Button + Volume Down Key again. You'll only have about a second to do so.
4. The LG logo will be displayed and, afterwards, it should boot you into the System Recovery Menu.
5. Release all keys when the System Recovery Menu screen is displayed.
6. Use the Volume Keys to scroll to the Factory data reset option and press the Power Button to confirm.

are you using download mode with lg up?
or recovery mode?

I don't know? I mean when I start lgup the first thing it does it pulls up a list of models and says it doesn't recognize my handset. How would I put it on download or recovery mode and which would I use?

So I am having the exact same issue with my phone. It is brand new however. Loops on LG screen. I tried this solution, however after the phone restarts, repress the keys, and the LG logo comes back on, it shows the unlocked bootloader screen, then goes back to the lg logo. It then cycles the unlocked bootloader screen and the LG screen infinitely. Do I have a brick on my hands?

Android 11/R Beta Bricked my P4XL today

If anyone knows how to fix this please help. I'm researching it now but I'm making this thread in hopes someone knows what I need to do.
I can boot the device and it gets to the lock screen and I can unlock it but then it keeps turning the screen off and going back to the lock screen. If I don't touch it it will continue to do this in a loop. If I press the power button it will turn the screen off and stay off. If I unlock the former process repeats and I can't do anything. I can restart the phone, or power it off. When I go to fastboot mode I can't find anywhere to factory reset it. I try to enter rescue or recovery mode and it justs boots to a screen with a dead android and says "no command".
I'm assuming I'm going to have to use adb to fix it. I've done this with phones in the past but I know nothing about the P4XL and haven't messed with my phones in a geeky manner in quite a while so my knowledge is rusty.
PS. The android 11 beta ran fine for a few days besides some normal bugs. All in all it worked fine. This problem randomly happened today while I was using soundcloud hooked to my JBL boombox.

Evidently I'm the only person in the world who has a bricked Pixel 4 XL with android 11 because I'm not finding any info on how to fix it. I'm not even finding anyone with the same problem.

When you are in the phase with the dead android and the "no command" hold the power button and just click the volume up button so you can go to the advanced recovery menu and from there hard reset your phone or install via adb an other rom.
Cheers.

Thanks! Worked! I found a tutorial on verizon's site saying to do what you just explained but it was saying to release both the power and volume up and when I did that, nothing would happen. Your instructions worked flawlessly. Thank you!

I had the same issue and it persisted until I gave up and got a replacement through my phone carrier via insurance. You may be out of luck my friend...

You shouldn't root or be installing beta software on your phone if you filed an insurance claim over a soft brick.

Phone stuck on boot loop and won't turn on

Phone got frozen while in Messenger, suddenly turned off and now it's stuck on boot loop. Holding volume down and power button does nothing, keeps it on boot loop. When I put it on charging, it heats up, but the charging logo does not show.
Anyone got any clue what might be the problem or how to solve it?

did you receive any pictures via messenger ? that used to be a thing that messed up phones because of one colour outside most phones RGB range.
a bootloop is a cycle, catch it at the right time and you can boot into recovery to clear cache and dalvik.
remember recovery and download mode need the cable plugged into a USB device to nowadays.
the instant the screen goes off hold volume up and power and then plug the cable into the phone (the other end already being in the PC).
if you did receive a file before your problem that'll still be there and the problem might persist. you might need to boot up into safe mode and delete something.

The phone got frozen at the main screen of Messenger, haven't received any messages or pics.
The thing I haven't mentioned but dk if it means anything, sometimes it gets to the Samsung logo, but then it goes off and turns back on.
Tried to hold volume up and power button couple of times, sometimes it would do a strong vibration and then do nothing, but I'll keep on trying.
Thanks for ur help

don't forget the USB cable, you can't manually boot recovery without it.

if you don't mind losing messages next time you could try clearing data on the messages app. you'd need to be pretty quick by the sound of it.
