T989 keeeps vibrating, shows splash screen and turns off!!

Hi, today i received this T989 that has this strange behavior. When i insert the battery it will try to boot by itself without touching the power button. But then it will turn off by itself also and starts to continuosly vibrate like its trying to boot but it wont. If i try to get to download mode with the JIG it will get to download mode but once i take the JIG out it will turn off again. My question is, could that be because it is bricked? Or maybe the power button damage? Perhaps the phone got wet? The sticker is kind of red, but if it was, i dont think it was too much because ive seen worst phones inside, i mean theres no sign of damp inside. I ask because if the case is that it might be bricked i will send it to mobiletech so they can fix it. But if its hardware then i will just have an expensive lcd display for sell lol..........

Maybe a stuck rocker button?

Thought the power button might be shorted. But i dunno! I didnt want to touch the mobo but since it looks like theres nothing to do except try that i guess ill change that button and see how it goes....

Did this end up working for you? I'm having the same issue...

Fairly certain its a power button issue. Went through the same thing myself in late July. Samsung logo shows, then it attempts to boot up only to be shut down and have the vibration pulse for a long time.
If you're able to Odin it back to stock, you can try and get T-Mobile or Samsung to replace it for you. If not, mobile tech videos has a button repair service.
Best of luck guys!

Hello, the same thing happened to me. I was able to bring it back to life by removing the back plate and disconnecting the motherboard completely. Then i inserted the jigg and put the battery back in. After 2 seconds i removed the jigg and connected the usb cable. Then i opened up odin 1.85 and the yellow com part stayed on i then flashed the program and my phones been working ever since. Good luck. Let me if you try it and if it worked for you.

Mine does it too.
Definitely the power button.

any solutions for the problem?

Hi I'm having the same problem as the original post - what's worst is that I'm in Argentina and I bought the phone on ebay. I will attempt your solution but what is the jigg???? As scared as I am to open up my phone, I am more scared about traveling for another month without a phone! :crying::crying::crying:
Any other suggestions before I perform an operation on my phone??
Please and Thank you!

Have you tried a different battery? It sounds like a bad battery. My wife's Skyrocket was doing this until I charged her battery outside of the phone. I wouldn't open the phone until you try charging the battery.

Simple solution is to tap or beat on the power button with an eraser many times.
This problem is common on t989 and it is caused by sticky power button.
Tapping the power button with Eraser or rubber multiple times should do it.

[Q] HTC One X is on a rebooting loop. How can I stop it?

My HTC One X is on a rebooting loop which I cannot stop. I cannot switch the phone on and it only stops rebooting when I allow the battery to drain. Once plugged into the mains it begins rebooting again. The rebooting only goes as far as the quietly brilliant screen then goes blank and a few seconds later fires up again to the same stage and again goes blank.
I know little about phones so any suggestion please keep simple? Thanks

Hold the power button + volume down button as long as it takes to get to the boatloader.

Hi
I have tried that but as soon as the boot loading screen appears - only for a second - it then vanishes before I can do anything and switches off ready to continue to the next loop.

I've now been voluming down for about 20mins and its the same thing. the boot screen does highlight in red that the battery power is too low for it to flash...no idea what that means....but if I leave it on charge the loop will go on and on wasting electricity ..
will it help to reboot if the battery had more power?

Do you have it on the wallcharger or the usb connection to the pc ?

when it's off charge the menu appears which has factory reset and reboot but it's not easy to do this as battery level is so low. I think the battery is on its last legs as before this problem happened the phone had been switching off during use and the battery level went critical at 1% power even though it was not being used. and it was recently charged up.
Is it possible to get a new battery for an HTC one X? I somehow doubt it...I may need to replace the whole thing.
Thanks for your help. I'll keep trying off charge once I charge it up a bit but I'm growing weary.

If you let it reboot continuously and hook it up to the pc it should charge the battery up real slowly. That's a chance you can try. You can also put in a hox+ battery.

Hi again
Good to know a change of battery is possible. I've given up now....My other half is gonna take the phone to a IT/gizmo wizard bloke who does repairs on gizmos and maybe he can fix it. The Vodafone guy had little idea but we were told something about a flash that might give it enough of a boost to enable a fastboot to work???
If that doesn't work I'll stick to my bonny wee Desire C for the moment.
Thanks for your help. I'll post the outcome of the rejuvenation or demise of my HTC One X.

Has your HTC One X gotten wet at all recently? This behaviour occurred in mine when the phone became wet. The problem was the Power Flex Cable, which can be replaced very cheaply.

What do you mean by power flex cable?
The top of the phone may have dipped into the bath...bad idea to google whilst bathing especially when one is tired.

Yep... it's going to be your Power Flex Cable. It's a small ribbon that goes from the power button down to the top of the motherboard. There are small circuits on it which get damaged when they come into contact with water. It's fairly easily replaceable. I wrote a post a while ago which should help you out if you want to give a manual fix a go:

Is my phone gone? Doesn't turn on, but vibrates

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?

HTC M8 Doesn't Boot, Red LED Flashing, Not Charging

HTC M8 doesn't boot red LED flashing not charging
Hi,
I have big problems with my HTC M8. It is 11 month old.
I is rooted, has 4.16.401.10 firmware, Android Revolution HD 43.0 and
S-off SunShine.
In the evening I put it on the charger with 61% battery left. The next morning it didn't start up anymore and the red LED was flashing.
The battery didn't charge and so long it doesn't boot up at all, I can't connect it to the PC. It is only shows the big battery sign when I connect it to the charger which disappears some seconds later.
I didn't want to send it to HTC for guarantee, because I couldn't put on stock software.
My lokal handy-doctor changed the battery... nothing!
He changed the USB connection... nothing.
The red LED keeps flashing, the battery doesn't charge, it only becomes warm, I cannot turn it on. I have tried to press the power-volume+ -volume- buttons, nothing.
I think HTC will charge me, if I sent it for guarantee, or does anyone have other experience?
What should I do? Any idea?

Try holding the power and vol up for a long time, maybe a minute or so, and see if there is any change.

That was one of the first things which I tried. It has no effect.

Try power+vol up, and also power+vol down, with and without wall charger connected. I've seen a couple people have luck with that. Otherwise, if it still won't work, its pretty much bricked.
Especially since you've already had a new battery installed, it may be a problem on the mainboard.

Since you've had a 3rd party take apart the phone, replace the battery, and replace the USB port, your warranty is void.

I did that so many times. It doesn't help. I think its a hardware problem.

As you tried all the things I suggested with no luck, I agree its probably a hardware problem.
This would have been justifiably covered under warranty, since its a hardware problem. And since the screen doesn't come on, they wouldn't have known it was ever bootloader unlocked, custom ROM, etc.
But now that you've had a repair shop open it, it will be obvious to HTC the phone has been opened and they will probably charge you for repair.

This isn't the "same problem" unless you (like the OP) took it to a repair shop, had them replace the battery and then the USB port? I doubt it.
Posting "I have the same problem" is just lazy, and doesn't give us the proper info for anyone to properly help.
How did this condition come about, did you just find the phone in this condition? Or were you flashing anything or any other actions to cause this condition?
Plug the wall charger (not connected to computer) overnight. Then hold the power and vol up buttons for a minute or 2, and see if there is any change.
Also try a different charger and cable.

Ok, sorry for the lazy answer.
So, yesterday the phone works fine, when i go to sleep.
Today, the alarm clock sounds, I woke up, and when i take the phone, the screen is black. Therefore, it didn't work.
I used another charger and cables, but don't work.
The S.O is sense stock, only had custom recovery, but I never used.
If i plug it to the computer, isn't recognized.
Maybe, you can know any solution for that?
A lot of times, I try, with power + vol up and power + vol down, for around 20 seconds.

Thanks for all help, but my phone didn't change the red flashing.
I think I have to accept that my phone died the red flashing death. RIP

Phone can't boot

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.
