Galxy s2 Vibrating and crashes at loading bar.

So i've looked around and no one that i've seen has the same exact problem as i do. Here's my post in another forums about my problem.
Here's my story about my Galaxy s2 for T-mobile. My phone randomly turned off 2 days and whenever i tried to turn it on, it would restart and basically never get pass the blue loading bar screen. Second, i found out about this boot loop sequence and i was able to do a factory wipe.
After i factory wiped the data etc off the phone, i was able to use it until it ran out of battery, but then after i found out it ran out of battery, it wouldn't let me turn it back on, it wouldn't get pass the loading screen, once again. On the other hand, i am able to go to recovery mode or download mode, but the phone shuts off before i can even try and click on the options i want.
Today, i found out that if i kept pressing power button consecutively on the phone, I'd be able to go to my home screen and basically act as if nothing ever happened, it'd function as a new phone! I then had the nerves of turning off my phone just to make sure it finally works now, but my hopes were crushed and now the pressing the power trick does not even work anymore. It would probably work one out of 10-15 times, and in the end it'd still restart. I am using a gingerbread galaxy s2. My friend tried using the usb jib on my phone, and it worked but whenever he tried to plug in the usb, the phone would just restart. I am extremely frustrated with this, and if you can help, please do so because it's important that i fix this phone. If you have any questions, please feel free to ask!
Hi there, thank you for the welcoming me to the forums. No, my phone is not rooted, it has always been gingerbread etc i never tried rooting because i never knew how:/ I believe this started when i was just browsing around facebook, so i'm not entirely sure what happened... Uhmm i tried going to download mode through the volume keys and power button when it's connected to usb to the i think it's odin3? and it'd be in the download mode but as soon as the computer says it's connected, the phone would just turn off again and bam, it's like nothing ever happened. My phone does charge when it's plugged in, but it doesn't show it's being charged but i remember my battery was dead last night and i charged it till today and now it's got power. ANd no i don't have a warranty:/ i really hope you can help me

[Q] Please help! Stuck in Bootloop, power button "stuck", no download mode!!

[Q] Please help! Stuck in Bootloop, power button "stuck", no download mode!!
I believe this has to do with the phone thinking the power button is constantly being pressed...
I'm looking for any advice. My s3 suddenly went into a boot loop this morning. It powers on for a few seconds and turns itself back off. I took my case off and noticed the power button is loose. Doing a little research, came across similar issues online caused by the main board going faulty and the phone thinking the power button is constantly being held down.
I know this because I can remove my battery, put it back in, and without even touching any buttons, the phone will attempt to power up.
I'm currently rooted and can't get into download mode for more than 3-5 seconds before it turns itself off. I was only once able to apply the perfect pressure by squeezing the side of the phone which allowed it to boot normally, but about 30 seconds later, the power menu appeared by itself and it turned off a few seconds later.
Has this happened to anyone else?? Anybody know how to go about fixing it??
My phone is still under warranty, but I can't flash back to stock.
Things I've tried:
Download mode
Recovery mode
Different battery
I haven't tried taking the phone apart yet. I want to get a replacement if possible. But just in case, has anybody repaired this themselves??
I'm really at a loss here. Any help is much appreciated!

Wow, crazy. I'm experiencing the same issue starting yesterday! I haven't tried swapping my battery yet, but the stuck power button makes so much more sense. I'm having all the same issues with not being able to stay in recovery mode or download mode for very long.
[EDIT]
My phone also seems to be reacting to static electricity. Say I let sit on my desk... It does nothing (not cycling reboots), if I pick it up it'll just start rebooting again. This leads me to believe that maybe it's not my power button but a battery or internal component issue.

Weird. I haven't noticed mine reacting to touch, but I did watch it try to start itself multiple times while sitting all by itself on my desk.
I'm going to take it to my carrier's in-store warranty center. They said with it rooted it can't be replaced, but they can try to repair the button if it's stuck.
We'll see what happens.
Has anybody had to replace their power button themselves before?

Well I just disassembled my S3. The power button mechanism seems to be just fine. It clicks down with pressure and releases just as I would expect it to. I'm thinking my issue is something electrical or battery.
Were you doing anything when your phone went in to boot loop? I was just texting someone and then.. poof!
What ROM are you using?

[Q] Stuck in recovery mode; no buttons working

I have a Google Galaxy Nexus and was using it last night (8/11)--it was a bit slow, as it has been for a few weeks, so I shut it down and hope restarting may help. When I started it back up, it was stuck on the "Google" word for about an hour and then I suppose lost power. I was not near a computer to plug it in.
When I got home, I plugged it into my pc to charge, then read online to hold down Power + Up + Down, which I did. I got to the Recover console with the "start" and little Android guy and the white arrows. However, no matter what I press (power, up, down) nothing happens. I cannot get past this screen. Also, my pc was trying to find drivers for it and couldn't. What should I do? And is there a way to preserve anything on the phone? I have not modified the phone in any way (rooted or whatnot).

I think you cannot move between options because the bootloader is locked. Can't say 100% that's the cause of it though.

Thank you for replying. If that is the case, how do I fix that?
And after it ran out of power, I charged it again and tried starting it normally and it started. So I have no idea what is going on. However Im now afraid to restart it in fear it will be stuck on the logo again. It still runs a bit slow.
So I guess I have 2 questions:
1) If I have to load it into recovery again and no buttons work, how do I fix that?
2) Since it did start again, but runs slow, what could be going on? Any tests I can run?
Thanks!

[q] screen is glitchy after dropping!

Two days ago, my T-Mobile Samsung Galaxy S3 dropped out of my coat pocket as i was running for the bus. I picked it up and saw the screen was cracked along the top left and bottom left hand side. Everything was working for the past two days and i figured i'll just wait till Christmas to get a new phone. This morning i took my phone off the charger and turned it on. The Samsung logo flashed, and then the boot animation for Slimrom (the custom rom i'm currently running on) flashed for about a second but then the screen went black. I did a battery pull but the weird thing is whenever i put my battery back in, even without touching the power button, it boots up by itself but then the screen goes black again. I can access TWRP and download mode but they both go black after a few seconds as well. I was able to successfully turn on my phone and have it fully function for about 15 minutes after putting it back on the charger, but it quickly blacked out again. It also keeps randomly booting up by itself which is weird. Im guessing this is a problem with the screen itself, but could it be a software issue because the device keeps booting up by itself? If it is the screen, will i have to buy a new one or is it not worth it? I've also tried using a different battery and i have the same issue so it can't be that. Any help is appreciated!

Sounds like an issue with the power button, it probably got stuck somehow either when you dropped it, or after you dropped it. Do a simple search for power button and you will find ways to fix it!

Holy crap i didn't even think of that! It makes total sense since every time i even tap my power button, even for just a second, it turns on. I've read around that clearing the cache or a factory reset could work. Is this true?

Unlikely, unless it's a software issue but it's always a possibility. Slam the phone against something to try to get the power button back into place, or open it up and try to see if you can fix it yourself, or replace it

The problem seems to be gone. I haven't had any issues for two days now. All i did was press the power button really hard multiple times. Thanks for you help man!

Nokia 6.1 seemingly hard bricked after reboot

I have a Nokia 6.1 TA-1043. I have not unlocked the bootloader, and it runs the default operating system (Android One, probably Nokia flavoured). It has gotten slower over the years, and it had a period where it crashed every now and then (sudden reboot). Anyway , some days ago I decided to reboot the phone because it was slow, and it instantly shut off. After waiting probably 20 seconds without response, I decided to hold the power button down to force it. I don't remember exactly what I did, but after trying to again hold the button down to turn it on again, it vibrated as usual but the screen remained black. I then most likely tried holding volume + and power to force another reboot, unsuccessfully. I then tried holding volume - and power to enter download mode. It might have vibrated, or I might have touched the cable making me think it vibrated, but nothing happened. I pressed some random buttons after I think.
Now, the phone does seem to charge. It gets warm when I plug in the charger. I've searched for hours on different forums, and some people say that their phone was magically resurrected after the battery went completely flat after few days. I have tried plugging the phone a bit and testing every button combination (including volume +, volume - and power at the same time) for a few days now. It's dead.
The phone is also seemingly not recognised at all on my windows 10 PC. Haven't tried on Linux.
I have a few theories:
1. The phone simply hard bricked itself due to some hardware failure.
2. I bricked the phone by (blindly due to screen being blank) entering recovery mode and unknowingly factory resetting the phone and shutting it off mid process.
3. The battery is messed up? Some suggest deconnecting the battery. It would require the use of a heat gun to even open the phone though.
I've seen some people suggest entering EDL-mode either by shorting some pins or using a modified USB-cable. However, that would either require opening a phone that isn't supposed to be opened easily, or plugging a modified USB-cable into my computer, nether of which seem safe. I've also seen people mention that whatever needs to be flashed in EDL-mode must be signed by Nokia, which I can't do obviously haha.
It's probably time to move on right? Has someone managed to get a phone in that state to work again?

Hi i can explain some of your theories:
The first one: It's impossible to make the phone hard bricked itself.
The second one: Factory reset is only wipe your data not the OS itself so if you Factory reset and force reboot it should get in to Download mode and you need to unlock bootloader to reflash the ROM. (I'm not in that situation so I'm not sure it's correct or not.)
The third one: No, I don't think so.
That's all so if you have any question ask me. Thanks!

Thanks for replying My phone seems unresponsive, so I haven't managed to get in to download mode, at least not visually on the screen. Also, my phone is not recognised on PC, making me suspect it's not really turned on. I also tried holding volume up + power for 40+ minutes by stuffing it between a few books when making dinner haha, and it still didn't respond. Would you move on in this situation?

I don't know because I'm not in that situation, but I had a similar one but only boot to download mode.
