For what I read on this forum, probably my phone is bricked, but I have to know it for sure.
The phone simply shudown and starts a bootloop without showing anything: the screen is switched on, then off, then on, then off and so on. I do not see the Mi logo or anything else. I've tryed to keep pressed the power button and volume up+power button without any change in the behaviour. Sometimes it vibrates.
The phone is locked with the official globabl MIUI, so it's not a fault with custom ROM or recovery.
So, it's bricked?
Good news: the phone isn't in bootloop, simply the display connector has come loose. I've reinserted it correctly simply pressing on the back on the phone.

Why did you open the phone in the first place, isn't that why the display connector came loose, it won't come loose unless you opened the phone.

I've never opened the phone. I have no idea how the connector has come loose.

I need to turn my phone on without using the power button. The power button on the top left side of the phone is broken and no longer works. This corner of the motherboard is slightly exposed, and I have previously turned the phone on by touching the mobo with a paperclip, but as far as I'm concerned it's just luck. I was hoping for either turning it on by computer, or a map of a mobo that showed what I could push/touch to turn the phone, if possible. Or, any other method. Thanks.
EDIT: I don't have my USB cable, so now I can't use any computer method anymore..
EDIT2: I found the problem: The small chip/power button attached to the motherboard came off. I'm hoping I can find someone in (Raleigh, NC) to solder it back on for me, assuming that it can be soldered.
What I was doing before with the paperclip was magic.. I just touched the pins and it turned on, but I can't do that anymore
EDIT3: Shorted out the power switch pins. My new power button is my battery

Look like your back to the paperclip then. Sorry, i had too, but seriously, I don't think it would work with the computer anyway. There's no way to communicate if it isn't on. Can you see where the button connects?
The only way to correct this is to either fix the mother board or continue using the paperclip. Unfortunatly most electronic devices like this, only have one "actual" method for turning them on. I do like your idea of bypassing the switch to turn the unit on though.
Updated. The power switch came off the motherboard.

im no expert...but that sounds like a not-so-good thing.
I fixed the issue.. sort of. Shorted out the power switch pins on the motherboard, so it stays "on" indefinitely. My new power button is my battery
A limiting fix, I guess.. but it works.
wow..you are not gonna let this one die huh? maybe its time for some parts? or a new phone?
Why should I let it die? Everything on the phone is fine, I just lost the power switch. Now I got the thing hotwired and it works fine.
I'm locking this thread....no more need for it.
Hello,
I've searched all XDA and Google, but couldn't find a reasonable explanation of my situation.
I use my Desire as a replacement for my Sensation, as it is in repair now.
I rooted and flashed my Desire. Everything worked.
I decided to try the LeeDroid ROM. All OK, but just after the reboot, the phone fell on the ground and the battery flew aroud $#@%#
After that I have the following situation:
- Removing the battery and connecting the phone to a power source, flashes the LED Amber and Green.
- Introducing the battery again, the LED turns Amber for "charging"
- When I push the Volume Down+Power Button, the LED turns off and everything is black. No LED, no vibration or whatsoever
It's impossible to enter Recovery or HBOOT in general.
I read there was a trick to power on the phone with a "USB Trick", but couldn't find how to. http://forum.xda-developers.com/showthread.php?t=1502777
Is it Bricked, so impossible to revive? Obviously no warranty anymore
Thanks for your input.
Wrong place for this question... but let me help you, it could be because of the fall, i mean most probably... i'm sure about that...

I say that the display connector might have disconnected itself when the phone hit the ground. You should try to tear your phone down and see if the connector actually fell out.

OK, I will try to open the phone, but I think that doesn't explain why the power button shuts the LED off when pushed.
I have to look for the very small screw drivers
Thanks.

After that the power button doesn't do anything. The phone doesn't even vibrate...
It all seems that phone works but your screen doesn't. Some connectors are disconnected or broken or your phone's screen is broken.

I will try to take my phone apart, but I don't have the small "star-shaped" screwdriver.

Don't try alternative, you'll ruin the screws. You can easily order it on e-bay and it's pretty cheap. I'm also sure you can find it in any hardware store, it's called TORX screwdriver.
Ok thanks!
I don't know what helped, but after repeatedly trying to switch on/off and connect/disconnect to USB power the phone booted again.
:laugh:
I managed to enter RECOVERY and flashed the Oxygen ROM and seems to work all fine and quick :good:
Thanks for you support :good::good::good:
Sorry if this question's been answered in another thread, I tried searching and couldn't find any question that exactly matched mine, or any response that solved the issue.
I purchased a used, unlocked Galaxy Nexus from ebay around a month or two ago, in near perfect condition -- this has been the first time I've had any problems with it. It's probably not applicable, but after the release of the dev preview for Ubuntu phone OS I rooted the phone and reinstalled the factory image "takju 4.2.2 (JDQ39)".
Anyway, a few hours ago I accidentally bumped my phone off of a counter in the kitchen onto the tile floor. I picked it up and looked it over, and noticed no visible damage whatsoever, although the plastic cover had been partially dislodged; however, the phone's screen was dark, and the phone was unresponsive. I took out the battery and replaced it, then held down the power button. The phone vibrated once, like it normally did when booting up, but the screen remained black and the phone unresponsive unless I removed and reinserted the cover again.
I've tried charging it, plugging it into my pc, removing both the battery pack and the SD card, taking the battery out and rebooting it while holding both power buttons down, but I still get no response (and my computer doesn't recognize the phone when I plug it in). After reading a post where someone had success reconnecting the display, I unscrewed and removed the casing, then disconnected and reconnected the display from the motherboard -- still nothing.
Is there anything else I can do, or is my phone beyond repair?
Did you check the other connections while you had the phone apart?

I opened it up again and took pictures, but I'm not very knowledgeable about this sort of thing, so I can't tell if anything's wrong or not. Should I remove the motherboard to get a better look at the display?
You're talking about the back cover which became dislodged upon impact? I'd say you're lucky that the phone still gives that vibrate. But it seems there are so many things that could go wrong from an impact. Do you have fastboot? [I know you said you tried holding down both volume buttons and power, but try pressing them first then tapping power.] If you don't have fastboot, then your only options would be omapflash and odin. If these do not work, it's gonna be hardware. Maybe the display is gone, if you get the vibrate but see nothing..
So i went out on a night out and my battery went flat whilst i was out. I come to start it after charging it up and it just keeps popping up with the start up screen for a split second and then going off. It keeps doing this until i unplug the charger or take the battery out. I managed to get into the reboot screen and tried starting it from there to no avail. The battery is only a couple of months old so that should be good.
I took it to a phone repair shop and they said the board was gone and that there was nothing that could be done with it. Is this the case?
I don't generally turn it off just keep charging when it gets below 20% battery life. I did however install solitaire since i last powered it down if this might have any influence on the situation.
Check if you can get into the bootloader. Hold volume down and power.

I have tried this but although it comes up with the bootloader screen it flashes off gain as with the boot up screen. It does not give you time to do anything in the bootloader.

Are you sure the battery isnt completely dead? Did you drop the phone or do anything that may have caused this, or did it just suddenly occur?

No i have charged and recharged it until the green light comes on. The chap at the shop tried another battery also and this had no effect on it.
I dont recall dropping it. It is in a substantial wallet holder so i would think that would take the brunt of the blow even if i had. But it worked fine all night until it powered down then it just started to play up.
Right while messing a bit further it seems to me that the on off button is constantly activating. If i just hold the return button it comes up with the reboot screen and allows me to choose the various options. If i hold the volume button the fastboot screen appears but disappears just as quickly. All of this happens with out me touching the on off button so it looks like it is constantly trying to start up. The button does not have any visible signs of damage. Is this a normal failure point for these phones?
If it charges completely while it's off, then the board should be fine. You can check the percentage in your recovery mode if you can get there.
If the board is fine, it either means that the button is stuck or you have some gunk short circuit in the button.
If it's gunk, you might get away with some rubbing alcohol, If it's in a spray can, even better. If it stuck, it should be opened and see what's keeping it pressed.
I hope this helps.

Hello all,
I have an S3, T-Mobile (T999). Yesterday while I was using it, it turned off by itself and now refuses to turn on. I have tried two different batteries and all it does is vibrates when I take the battery out and put it back in. I cannot get into recovery.
It was rooted and I had the PacMan ROM on it. To make things worse, the mcro-USB port is not functioning so plugging in into the computer doesn't do anything (I was using Anker wall-charging batteries to charge the phone).
Is my phone bricked somehow? Any troubleshooting tips?
Does it do anything other than vibrate? Does it sound like it comes on but the screen is just dead? Do you see anything happen on the screen? Unfortunately, without a functioning usb jack, theres not a lot you can do. Cant even flash the stock firmware....Only other thing you can try that I can think of is to find another S3 and swap the motherboards to test on a known good device.

Thanks for the reply DocHoliday. Today, after charging my Anker battery, it vibrated as usual but then I saw the Galaxy logo appear on the screen, but then it went away and the phone died again, so the screen is functioning.
I wonder if it is a battery problem; however, I have tried two different Anker batteries. I might try to find a stock S3 battery and try again. Will keep this thread updated.

Does it try to turn on on its own when you put the battery in? If so it may be a power button issue. Either way, you might want to take it apart and make sure the button appears ok, and also check/reseat all ribbon connectors. Kinda doubtful its a battery issue, but I guess it is possible.
Did you try to go download mode or to the recovery (What ever u have)????...Just to know the reaction of the phone.If u can then is not hardware related

DocHoliday77,
I opened up the phone yesterday. The power button has no ribbon on it. It's connected to a simple surface mount push button. I tried pushing the button with the screw driver to rule out the actual button not making the proper contact, but it still wouldn't turn on. It still vibrates when I put in the Anker battery though.I think what I'll do today is test the voltage on the battery before putting it into the phone to make sure its not dead. Unfortunately, I could not find the stock battery that came with the phone.

I know the button has no cable attached, I meant for you to unplug and reseat all ribbon cables that are there. I think there are 3 or 4....maybe 5. There are disassembly vids you can reference though. As for the power button, it has been known to go bad. We've had it reported quite a few times around here in the past several months. Sometimes just jiggling it, or messing with it a little seems to help, otherwise itd have to be replaced. If you put the battery in, and the phone tries to power on without you pressing power, this is most likely the problem. From what you have said though, I doubt this is your issue. It could simply be memory going bad as well. I have seen a few reports of this. Unfortunately, short of replacing the motherboard, there is no fix for this.
Im, not saying that is the problem btw. Just a possibility.

I ordered a replacement button today. It would be another 'low-hanging fruit' possibility and it was only $3 for the button on eBay. I'll de-solder the old one off and solder the new one on. Will update this thread after doing so. It is a mechanical button, so I agree, it could have messed up some how.
hey even i have nokia x it doent on doesnt vibrate just like total dead what should i do batery is ok some problem while flashing it with me
Update Please

Hi. I have the exact same problem as you had, so I was wondering whether or not this worked?
