My springboard tablet stopped working without being plugged in almost as soon as I got it from T-Mobile. It fell from a height of about one foot onto a carpeted surface and stopped working. I finally opened it up and found out that the bracket that clipped and attached the the battery to the circuit board had cracked and broken away from the board. And I couldn't figure out how to solder such fine solders with my limited equipment and experience. My dilemma is that since it only works when plugged in, it automatically turns on when plugged in and I can't do the hard reset by holding the power button down and the volume down button until it vibrates and then pushing the volume up button. Does anybody have any suggestions on how to return the device to stock condition. How can I work around this hardware fault.

hi, i replaced the digitizer on my hd2 (uk) and now after screwing it all together, it wont boot, when i plug in the charger, the red charging light lights up, but nothing else.
it worked before i changed it, do you think i broke something inside? or fitted it incorrectly?
i mean would it not start if it was fitted incorrectly?
its not dead if the charge light lights up right?
thanks
also have the same problem...please help
Did you plug the motherboard in? I recently had an issue with my mini usb (broke off the motherboard), took it a part and tried to solider it back on (with no success) put it all back together and it would not turn on. Thankfully I didn't put it completely back together and noticed I didn't connect the little ribbon cable to the motherboard. Also, in the process somehow now my digitizer doesn't work fubar!
I just got this old phone from my friend after he upgraded. It's a solid phone but I'm having 2 issues.
1. The power button doesn't have the nice clicking feel to it. I opened the phone up and discovered the power button was one that I have not seen before. Is this button soldered onto the board? I would like to replace it myself, I have tried looking up power button fixes but was not able to find any results with this particular button type. It's usually the ribbon cable type deal with the flat disk contact kinda deal. Any idea where I can find some instructions and the buttons themselves?
2. I have a problem with the phone not powering down. After shutting the phone down the phone boots right back up or the screen shows the charging animation. Also the screen never goes into sleep mode it only goes into the dim mode. I looked up this problem and it seems to be a common one, a problem with the micro usb slot. I ordered the whole usb slot and the board its attached to. My question for this one is how difficult is the install?

I just replaced the screen one of my i777's. I followed this great guide my LE55ONS on YouTube. It was for I i9100, but they are almost the same phone. Along the way in the video he explains how to replace everything in the phone, including the microUSB board and flex cable, which if i remember was a pretty easy fix. As for the power button, i would try maybe putting a little piece of paper or cardboard or foam or something inside the phone right next to the button, that might make it more ferm when pushed.
Hope this helped.
Here's the link to the video :

Thanks for the reply, yes I saw the video too, it was helpful but that dang power button is so mushy it feels horrible. A little update though I was able to fix the micro usb port by cleaning it with a brush then bending the pins towards the screen, it appears that over time the row of pins gets pushed too far down and shorts the assembly. Power problems fixed but not the power button. Only place I can find that even has the power button repair service is mobiletechvideos

You might want to check the forums for your device, as the hardware between the I777 and the T898 are very different.

Okkay, so I have taken phones apart before and never had any trouble.. but theres always something that can go wrong.
My dumbass went to the beach with my Note 2, and got sand in the audio jack port, and i cleaned it out as good as i could and well i still couldnt listen with headphones. So i decided finally to take the back off and get a better look. There was indeed sand still in the audio port and i gently got it out.
but of course i accidently tore the power flex cable /button ribbon on my way of taking the phone apart. so, i ordered a replacement flex cable. replaced it, and yay the phone does not still power on. this is the type of cable that doesnt need soldering, its just a plug in/push type.
so, the phone does NOT power on at all..
the screen DEF does NOT have damage to it, .. considering everything was perfect before my dumbass decided to take the back off the phone.....nothing else is damaged i went to extremes to take the board off even to make sure, everything is fine!
so, other than the power cable/button, what could be causing the phone not to power on at all now?
So when I was replacing the screen and the frame on my phone I realized the power button had a flex cable, one gentle movement and now it broke. I was able to order a new one but it's been 3 weeks since I had the phone taken apart and I don't remember how the flex cable attaches to the frame so that the button can actually touch it? If somebody could pop off their case and take a picture and/or undo their power button and describe how it goes back together that would be great!

In my experience, the power flex cable is soldered to the motherboard usually. You may have either buy a soldering iron and do the most precise work you've ever done in your life or contact a phone store. Sorry if this wasn't helpful.
The power button on a samsung note 2 that I inherited fails to work. The phone was left outside and rained on so when I first got it the screen did not work and I thought it was going to be trash however after drying it out and properly cleaning it the device screen works now and it will turn on when plugged in. I have one of the dongles that forces the phone into recovery but the power button just plain does not work. I don't know what to do but I would like to be able to use this phone.
I've dismantled a few of these phones and once I ruined a power button while sliding the the tool past it to pop the case apart. The power button is part of another assembly but can be replaced. Any version of the phone (Sprint/ATT/etc) will use the same subassembly for the power button. If that is the problem, you can swap it out.
Otherwise, you may have corrosion issues. I have brought older "dumb" phones back by spraying the circuit boards w/electrowash cleaner, scrubbing w/a toothbrush, and blowing off with an air compressor. Be sure to remove all ribbon connectors and scrub both sides of the connector. Also: DON'T JUST SPRAY THE PHONE WITH THE BACK OFF! the electrowash will stay visible the display, so do this in a controlled manner.
