so today i had fixed my s4 from this rebooting problem.
i was using the phone like everyday then the phone turned off by it self.
when i remove the battery and put it again the phone starts by it self going to a boot loop.
so i went to the samsung center, they told me its a software problem and it need to be flashed by a "j-tag" (software device) and they dont have it.
so i was confused
i have figured out that i cant go to recovery and i can go to the download mode for few seconds BUT! without pressing the power key!
the service center ignored me and refused to fix it.
so my last hope is to fix it by my self, so i did this!
You Have Two Options!!!
1- Hit the phone with the ground softly several times (stupid but fixed my problem)
2- Go to the power button by removing the screws under the phone back cover and release the button (by your self or anyone can handle this) :fingers-crossed:

How can it be the same if he wasnt able to enter recovery.....
For me there was some issue with the power button getting pressed automatically. ..opening body loosened it..n fixed.. i also had another issue with sview black screen blinking..issue with the Magnetometer. .loosening the L1 screw fixed that. .may b tge button got magnetised somehow. .
i too had the same problem. i found it to be a defective power button as when i just pressed the volume and menu buttons i could get into recovery or download menu correspondingly without additionally clicking the power button.
Hi. I faced this issue as well and the best part it, the button isnt stuck. I've tried pressing and releasing it multiple times, dismantled and check if the button is stuck etc. However, the issue persist, and the exact same symptom which is; able to only go to download mode for a few seconds.
Need some advices here! Thanks!

Hi,
I got my HTC HD2 only a couple of weeks ago, and I already got a problem with it
The thing is, that I can't boot it up properly; when pressing the "Turn on/Turn off/hang up"-buttom, it boots by comin' up with the white screen with the green "HTC"-logo in the middle and some system information in the left buttom.
Afterwards the animation with "quietly brilliant" comes up and the Windows logo with the orange background comes up - and then it turns off and boots up again.
I've tried to...
* reset it (not hard reset - I have some contacts that I don't wanna loose).
* charge it up (I can, when the windows-logo appears, see, that the battery's full)
* pull out the battery for several hours
Please help - I'm very sad about that I used tons of money on a device, that now won't work.
Is there any way, where I can solve the problem without loosing all my contacts?
I did it!
Ok, found out that all my contacts were synch'ed with my gmail.
I hard-resetted it, and it works now.
Thanks for your help
Lol well done!
For people that dont have push/exchange contacts etc, always backup using myphone, spb, sprite or other software.
Cant tell you enough how important it is to back up, unless you like loosing everything right?
Greetz.
Boot problem..
Hello there,
I bought my HTC HD2 like 2 months ago, and the first two days it froze like thrice !
Now, suddenly i find it turned off then when i try to boot it up, it get stuck on the white screen with the green "htc" and information in red to the bottom left. It hangs there!
It did later show the following black screen with white text:
"The device is unable to boot because either you have turned off the device incorrectly or tired to install an application from untrusted source. Press Volume Up to reset your decice or press any other button to cancel. This operation will delete all your personal data and restore the device to it's factory settings"
but the thing is, i can't press anything at this stage, nothing happens....
I did try to hardware reset, charge, remove battery and put back, etc..

You tried:
1. With the phone turned off, press and hold the VOLUME UP and VOLUME DOWN buttons, then press the END/POWER button shortly and release it.
2. Release the VOLUME UP and VOLUME DOWN buttons.
3. Press the VOLUME UP button to perform the hard reset, or press any other button to cancel the reset.
If that dont work try flashing a new rom using mtty.
If that still doesnt work I would expect it to be a hardware problem, i would send it back to htc or if without warranty take it to a Phoneshop (or open yourself), probably a wires loose or something.
Thank you for replying... but sadly no, it didn't work
I do have warranty, ill take care of that..
Thank you again.
did hard reset and returned to factory settings. all my installed applications were lost. pity.
All I wanted is to install the @#$%% russian keyboard!
ALWAYS backup first. Simple.

If its brand new out of the box, id take it back and get a different one. If its second hand, see if you can get into bootloader. If you can you can then flash a stock htc rom, if not its back to the shop.

i have the same problem But how i can Backup when phone is turned off
Hi guys,
I have a little problem where my phone's power button will not function in any way, long presses, short, almost embedding my thumb in it, all to no avail. This is doubly dissapointing as I have just installed the latest dexter plus patch to fix the problem. I still had the problem on the previous version and I thought a clean start may fix it. The only way I can get the screen on is to press the media play button! Which of course isn't doing anything on dexter.
Hunches:
I have been playing with a light sensor program and using a 3 second press to turn the phone off, I am only thinking this is related as when I re-installed then turned off the phone using a battery pull, that now the media gallery button will now not work at all, so that is a change.
Second, the power button is buggered. Seems unlikely as everthing feels normal, no big drops have occurred from heights, and the button is travelling in and out as usual.
I have also noticed that as soon as I re-insert a battery that the phone starts immediately, the M pops up as if it is already posting. So maybe it is stuck down?? Again, I don't think so, as the mechanism is working per usual.
If anyone can help it would be fantastic, you guys haven't let me down yet, and this thing is purring, but unfortunately I cannot use it lol. Just my luck.
Thanks in advance
another thing, still not solved
Another thing is happening, the phone screen turns on "after" pressing the power button, it may be once or a few times, and then pressing the gallery button.?!?!
Also, at random times it plays a podcast on my phone, the exact same podcast, and from the start, though the duration may be a few seconds then repeat, or it may go for ages, its quite a rude podcast too which has caused me to throw my phone under the car seat to shut it up when people have been trying to talk to me, as you can imagine its quite embarassing.
There are no services or apps running that I can find related to music, it may happen after pressing the camera button, or opening a website.
It is still going really fast though. And I have also reinstalled the light sensor program so I can turn it on and off without causing damage to the power button.
Thanks again everyone.

please clarify
sure, so the only way I can get the screen to turn back on, after turning off as per display power saving preferences, is by pressing the power button, maybe a couple of times, then following that up by pressing the gallery button next to the shutter button, pressing the gallery button doesn't seem to be working to turn the screen on now, but this combo is.
I hope that helped.
Cheers.
EDIT:::
The gallery button alone is working again. sorry guys.
You might just want to reflash it to stock to see if this resolves the problem.
Yeah I think I may have to.
Before I do., I was reading a post on a different forum where another person was having a similar issue. They seemed to solve the problem by using rom manager to boot to a manual restore menu where there was a button tester section, after using it the power button worked for them. I tried but after resetting it displayed a triangle graphic then rebooted.
Is there any way to do this with our open recovery program or any other utility to test the functionality or maybe reset the button or apply a patch etc.
Thanks again :-D

Getting Frustrating
Alright so I followed your advice on your videos on how to reflash to stock, so of course my bootloader does not show up the same as yours on the video. I can get to the bootloader fine, using the button combo or by using quick boot > bootloader, both have the exact same result, the boot loader screens as follows:
Bootloader Fastboot mode
80.89
and that is it....
Also, my computer using rsdlite does not acknowledge the phone, not omap drivers loading etc. Followed your instructions exactly.
This is frustrating me to no end lol.
I am guessing that because I can get to the bootloader with combo no problem, that the buttons physical connections are working.. At least thats a positive.
Can I flash to stock with openrecovery? Or maybe to an earlier version of Dexters froyo? Other ideas?
Any help would be much appreciated guys, trying to use this phone at work with light sensors to turn off screen is not as easy as they say. OMG....
Thanks so much

The fastboot bootloader isn't the right one. So... if you hold volume up + camera shutter while powering on you end up in fastboot? That's really weird.
Maybe your keys have been remapped somehow? Does anyone know a chord to boot fastboot? Perhaps check to see if your USB port is clean?
Lmao
Just my luck to have a weird problem. I thought it may have been remapped so I have been trying the program buttonremap. It doesn't seem to let me do anything except stop the buttons I re assign doing anything :'(
Does anyone have a proper key mapping file that I can replace with my faulty one to hopefully fix it?
Or any other ideas?
Cheers everyone

Just checked my system / user / keylayout folder. How many files are supposed to be inside, there are a few. I checked the contents of some and they seemed to be the same. Just an idea.... thanks again.

Ok installed anyunlock it allows you to use any physical button to unlock the screen. It doesn't respond when the Power button is pressed, it responded fine to volume rockers, gallery and shutter though.
Anyone know if this would mean for sure its a physical problem before I crack it open and try and fix it.
Thanks guys.

Breakthrough!
I am pretty sure I have fixed the problem, I tapped the phone fairly hard on its sides and back, and lo and behold after a battery pull and replacement it didn't turn itself on, I waited, nothing, so then I held the power button and it started up!!!!
But....I have another problem that happened before that, I am stuck in the boot animation that open recovery uses before going into its program (i.e. where you can load nandroid, wipe dalvik cache etc).
I was about to load a new rom, and was in open recovery, had installed it and about to do the reset and the phone turned itself off, and thats when I got the problem with the sticking boot animation.
So just to be clear, I am stuck in a boot loop, but not with the M logo, the restore logo.
I hope the power button solution can help someone else, as random as it is.
If anyone could help me get out of this boot loop without flashing stock that would be great. ( i can get to the real bootloader now btw)
Thanks again everyone.
Solved it all
Just took the sd card out and rebooted. And the power is getting better after banging it.
Thanks to all.

So, is your conclusion is that the button was stuck and the banging freed it? It doesn't restick?
The Button is not perfect still. Sometimes over sensitive Occasionally it will not even work but it works most of the time. I am just wondering what cleaning solution I could use to free it some more.
It has certainly been a trying problem. Cheers for the help.
Now I need to figure out why I have this strange ghosting on the top of my screen.....

Samsung Galaxy S2 Power Button Not Working
Hi Guys,
Any solution for the power button problem? Current latest Android 2.3.3 Samsung Galaxy S2 also having the same power button problem. Most of the time I can't use my power button to turn on/off the screen (wake/sleep) and there's no menu for long tap as well. Luckily it does wake when i press the only physical Samsung center button.
What i have already tried: Factory Reset, disable Power Saving Mode, Spare Part+ (apps), Screen Off and Lock (apps), and all won't help.
Is there any current updates or patches to allow the power button to work as usual?
Thank you.
take it to the samsung technical centre
Thats if you still have warranty

won't help because this is the 3rd phone replacement from the shop with the same problem. 100% Android software problem.
Hey guys. I'm pretty desperate so i decided to make this thread.
Here is my problem:
I have changed screen on my phone today. Everything went without any problems since I tried to turn on the phone.
When I tried to turn it on I can see only MI logo on display ... Then after couple of seconds phone will restart automatically and goes into Recovery mode.
I tried to boot it from there without any results. Also tried to reset and wipe data without any results.
The biggest problem is that I cant even get into Fastboot menu by pressing Power button + volume down button. So I cant connect my phone with PC and try to flash new ROM.
Any suggestions? I would be really thankful for any advice.
Thank you very much.

Did you follow a tutorial for replacing the screen on your device? Where did you get the screen from? Was your screen replacement just the Touch Panel or the full screen replacement with LCD + Touch Panel? Was it an actual Xiaomi part or an aftermarket part? I would take your device apart again and make sure you didn't leave something loose or disconnected.
Quick question. Was you old display still working where you could see what was going on? Like, was it just cracked or was it completely inoperable?

Thanks for reply. Yes I followed complete tutorial on youtube. Screen is from ebay. It should be original. I replaced full screen ( lcd + touch panel ).
So found simillar problem as mine - due to improper installation of back cover volume up button was pressed which caused that phone went to recovery menu after start ... ( you have to hold volume up + power key to get to Recovery menu). So I tried to dismantle it again but it didnt help. Still have same problem.
Yes old display is alright. I can see everything just touch screen is broken so I cant do anything on it. But I cant imagine this would be problem of display ....
Give your craftsmanship and handiwork the benefit of the doubt and install your old LCD+Touch Panel and see what happens. If you have everything installed correctly with every cable connected to it proper location then you should be able to boot normally.

Dear Learned ones,
I recently purchased a second hand Samsung S7 Edge phone, only to find out that it has a software KingRoot installed in it. I went into kingroot and then pressed some options to unroot it and then deleted kingroot app thinking it would have done the job but apparently not.
Now I have been trying to follow some youtube videos how to factory restore the phone but am stuck. The phone isn't simply going into download mode at all. I tried pressing vol down + power + main button but it simply does not work.
I would greatly appreciate if you can please help me with how do I go about restoring it to the factory mode.
Peace

Hi mate
Sometimes is tricky to get into download mode , when system is not 100% ok timing becomes an issue, keep trying it should work
Once there just flash a fresh firmware
Sometimes holding Volume Down & Home & Power until the phone reboots twice will work if doing it only once fails
Thank you, both for your replies and assistance. I have tried holding all three buttons down for good minute but nothing happens. It feels like that the screen lights up a little and then goes off again. I have been trying it over and over again few times but nothing happens
When I do it few times, it then comes back saying Android is starting... Optimising app XX of 102 and then starts normal again.
Is there a way i can insert two pictures here for you to see the main screen?

As i said , is a matter of timing , keep trying , hold and release try again
So you can boot? are you rooted?
In the reply window is paperclip symbol click it there you can attach picture...but i am not sure if you are yet allowed...
Out-of-the blue my phone rebooted while doing nothing (no new ROM or anything) and got into a bootloop. If I try to enter recovery, it will only show TWRP splash but after 0.5 second, it will reboot automatically. Same for fastboot, I do see the fastboot logo, but again after 0.5 second it will reboot. After some time, the battery ran out, and also the charging screen when plugging the phone in while switched off shows bootloop: 0.5 second of battery screen and bootloops there as well.
I tried MiFlash, aiming to start the flashing very quickly once I enter fastboot, but although it starts uploading stuff (so it does make a connection), it again crashes after 0.5 second again.
There are no Xiaomi service centers in my country and the phone is out-of-warranty. I still would love to revive it, but am out of ideas on how to achieve this if the bootloop seems to be so extremely persistent.
Any ideas would be appreciated!
Hey, I have the exact same issue. Did you ever find a solution about it? Boot looping every few seconds and no fast boot or recovery.
Just in case this can help someone, seems like there was a bad contact on the power button leaving it pressed? I blew some compressed air on the power button opening and it stopped rebooting.
Thanks for the tip! After two months collecting dust (and me taking over my sister in law's mix2s) I took it out, blowed out at the power button and it came to life again!

My problem looked exactly like this!
I did not even open the case, just blew air around power button. Now a few weeks later, the phone still works fine. Maybe I blew the stuff deeper into the phone doing it like this? Anyway, as long as it doesn't come back, I'm happy. And if it would come back, there is still the option of opening it.
I tried pushing compressed air without opening the phone but still facing the same issue. Anyone tried opening and succeeded by cleaning the power button or solved this by another method?
