Power Button Cable Ripped - myTouch 4G Q&A, Help & Troubleshooting

So I was trying to replace a friends digitizer screen and in the process of doing so I ended up ripping the power button ribbon cable. When I plug the phone in with the battery in the orange light signifying it's charging goes one which I assume is somewhat of a good sign. But I still have the problem of the power button not working. Is there anyway I can turn this phone on with the power button?

"Turn this phone on with the power button"
lol yeah sure just press it
Assuming that was a typo and you cannot turn it on; try to open adb then do "adb reboot"
Also I heard that when plugged in, the phone will boot into recovery if you are using CWM Touch (we have it on the dev section )
Hope I helped.

weird power button operation-g3 wiz

Hi guys, I hope I can type this coherently.
I have a g3 wizard that I have flashed many times over the last year or so. Lately the power button has stopped working. I can get the phone to turn on by plugging it in, and then holding in the camera/voice buttons and THEN hitting the power button. It goes into the rainbow screen, and I just soft reset via the hole on the side. At that point it is on and running fine, but the power button does nothing.
The power button does nothing at all unless I plug the phone in, and then only if I go to bootloader. It seems to work just fine to do that-which is what is stumping me. I thought the button was just broken. The charge/battery lights do come on.
For now I have it set to never turn off, so I try to make sure it doesn't run too low. The battery life seems ok. Any tips? I want to be able to put the phone to sleep again...
thanks

Might be bricked... need experienced opinions.

Ok, I have a T-Mobile Mytouch 3G (Magic) which was Rooted. I used FastBootCommander to flash one of the Gingerbread .zip files and it failed.
Now, I can't even boot the phone. If I remove the battery, then replace it and hook up my PC cable, the amber light comes on. If I then hit the power button, the amber light goes off and nothing else happens, and at that point I can only remove the battery again to get the amber light to come back.
If I hold the trackball and hit the power button I get the blue light, but I still
can't do anything from there.
Am I completely bricked? Any tricks I'm missing?
Hmm...
Remove battery and place it back after 5-10 seconds. It can help when phone is bootlooping.
Then press and hold Back + Power. Phone will start into fastboot-mode
Other combinations:
Home + Power (recovery)
VolumeDown + Power (hboot)
If any combination will success - hardware is working properly, but need ROM)
None of the combos are working except for Trackball + Power, and that only
gives me the blue light.
totally bricked i think
your case like mine before,if we plug charging and push power button, light goes off..
all you can do is JTAG i think..
Yeah. A brick.
McCordRM, what files did you flash? I will analyze them...
JTAG do
success with JTAG,
last chance to wake up from dead(Bricked)

tab bricked need help

Hello all,
My mother got an a500 about seven months ago and the other day she put it to charge and the next day it wouldn't turn on at all, just a black screen. When the charger is plugged in, the power button glows white. Take it off charge and the light goes out and that's all it will do.
I have tried searching through multiple forums and I have tried all the solutions I have found. I tried pressing the reset button near the usb plug, I tried a hard reset by holding the power and volume + buttons multiple ways, i.e. I held them both for thirty seconds, held the vol button and pressed power for three seconds and about every other iteration I could find. Nothing happened not even a vibration like from what I've read it is supposed to do. I downloaded the update.acer.zip file and put it on an sd card and tried flashing it by holding the power and vol - buttons, still nothing.
The tab has not been moded in any way, however, God only knows what apps my mother way have downloaded to it...
I am at my wits end and I don't know if I'm doing something wrong or what. Any help would be greatly appreciated. I am a noob so it wouldn't surprise me if I am not doing the flashing right or if I have the wrong files, all the links I found on the forums were non functional and I had to download it from filecorp.com.
Thanks in advance!

The white light when plugged to the charger just indicates it's fully charged.
Test 1. Press and hold the PWR button for 7 seconds, release, wait a couple seconds to see if it responds, then press and hold for another 7 seconds. See if it responds.This is to check if the tab is in Sleep of Death (SOD)
Test 2. Using a paper clip, press and hold the pinhole reset (near USB) and then press and hold PWR. After 4 seconds release PWR, 1 second later release pinhole. See if is vibrates and goes into APX mode, (tab should vibrate once with a black screen and white PWR button) if it does, press and hold PWR only for a few seconds. Wait a couple seconds, then PWR on tab by holding PWR about 6 or 7 seconds.
Test 2 is just to see if the tab responds to anything,
If you can't get any response from the above, then it's best to turn it in for repair.

@Moscow Desire: he pressed the reset button already so it is probably not SoD. Unless SoD makes reset button unresponsive too.
My tab does not vibrate when entering APX mode at all. Only the white power button LED turns on and the screen stays off.
@Core645: try this at first
- disconnect charger so the LED turns off
- hold power button for about 5 seconds
If the power button LED turns white and nothing else is happening then your tab is stuck in APX mode. You can confirm this by connecting micro USB cable from your PC. If you have windows it'll ask for drivers for Nvidia Download Mode or something like that.
Then check what Moscow Desire suggests with the reset button. I only ask you do my check at first because by holding reset you would achieve the same result and you wouldn't know if it is stuck in APX or you just forced it to APX by holding reset button.

Nexus 4 Red light Problem

Hey, my Nexus 4 died a month ago. i have tried many things from the internet, and none of them worked.
When i'm holding the volume down + power button, and inserting the USB cable, the red light is coming up, and it's Solid Red Light, and after about 10-15 second, it disappear. i sent it to one private lab, and they didn't succeed to fix it.
what can i do??
*Note: i'm going to give the device to another Lab - but i still want to hear you people
Simulate a battery pull by holding volume UP and power button simultaneously for one minute, see if that helps get you back running to the point you can at least charge it up and factory reset.
I've had the Red light of dead yesterday because i had critical battery level and didnt charge
I responsed immediately and pressed volume down + power and it entered

And then connected the charger and pressed power button again to select START
It booted and started charging

Is it possible to boot phone with a broken power button?

After replacing the battery in my X11575, the power button seems to be broken now. After taking it to a local repair shop, I was told that some of the components were damaged while the battery was being installed. Though the power button is broken both volume buttons still seem to be functional. With the volume buttons still working, is there any way to turn on the phone while in recovery mode without a power button? Thanks
If you have a computer with fastboot set up this might get it. I'm not certain if this will work, but it is worth a try (works on some Snapdragon devices). Start with the computer booted up and a USB cable plugged into it. Hold vol down on the phone and plug in the USB cable. That might boot it into fastboot. If it works enter this command on the computer and it should reboot normally:
Code:
fastboot reboot

Yes. This happened to me with a Moto X 2nd Gen, with a broken power flex.
First you need to remove the back cover. Use the iFixit guide because it'll tell you where flex cables are located under the cover so you don't snag or break them.
Then you'll see a ZIF connector just under the flash. If you short the 1st and 4th pin, it will turn on. You can use a paperclip, staple, etc. If you can't get it to cut on, just keep trying. Those pins go to switches on the board, so you won't short out anything electrical by messing with it with the power off.
(Only short them for as long as you would push the power button down to turn the phone on. If you hold it for too long it'll boot into the bootloader, which actually would be fine now that I'm thinking about it, since you can reboot to system from there.)
Just make sure it's not plugged in when you are jumping the lines.
I included some pics I just took with a X Pure/Style I just replaced the display on and confirmed it's the same as the X 2nd Gen.
If you have issues, just hit me back.
