Hi,
My HOX had some bad water damage recently and I would be fully convinced the motherboard is screwed except for the fact when I connect it to the charger two of my lights at the bottom are lit up and the back part where the processor sits is warm.
The problem is the ribbon at the top ripped and when I am looking at the power button that seems to be what connects the buttons to the motherboard.
Is there any other way I can use the power button without buying a whole new front screen etc?
Thanks.
The lights have no bearing on the condition of the motherboard.
Find the contacts that touch when pressing power and then close the circuit with something conductive like a wire. that simulates the power button being pressed on most PCBs. Even if that motherboard powers on, it would be unethical to sell a board that's been submerged in water. The chances of it being in perfect working condition are extremely low.
I'd give up if I was you and I know what I'm doing

I made the mistake of not turning it off immediately and tried pressing buttons.
The volume buttons and power buttons went crazy for a bit then the LED flash flicked on and off a while then eventually all the harware buttons failed.
What replacement parts do you guys suggest I try getting? Could the problem be isolated to the power/volume switch piece?
Did you leave it to dry for a week, if it's bought second hand I guess buying a device with a broken display but yet functioning and replace the circuit board..don't know if sammy still do repairs but I guess how much your willing to pay..
ebay should have what your looking for
that's a brilliant idea! no I didnt leave it out to dry for a week before I pressed buttons on my wet device (the absolute most essential part of saving a water damaged device, don't do it people!)

which version of the tab ???
"Could the problem be isolated to the power/volume switch piece?" - No
I have a verizon s6
The Volume buttons work, Home button works, but the power button does not seem to not be working
I plug the phone into charger and it shows 99%. When the battery charging animation display turns off after a few seconds, I can wake the phone up with either of the volume keys and home keys, but the power button will not wake the phone up.
If its something hardware (mobo/mainboard) How is the battery charging animation display being executed?
I have disassembled it now. Water damage, corrosion on contacts. I cleaned them, but still not working.
How can I test the logic board? Or try to power it on without the power button? If the charging battery animation shows, does this mean the logic board is working or not?
I don't really know hardware at all, but I do know Samsung considers water damage Beyond Economical Repair.
Something is interfering with the power button or the way it's detected by the device....but what that means as far as the mobo....I have no idea.
Ok, I looked closely at the board and looked for the contacts points that the physical buttons were going to.
Pulling from my automotive wiring experience, I tinkered/brainstormed around for a little bit....then I got a little piece of aluminum foil and "jumped" the two contacts points......and whattaya know...SAMSUNG GALAXY S6 POWERED BY ANDROID!!
So now I have to figure out how to get this working with the phone fully assembled.....
Problem solved (AFAIK)
I placed a piece of foil physically in-between the power button ribbon cable contact pad and the contact point on the logic board.
Working as normal. Now I can uninstall these "power button to volume rocker" apps and re-seal the backglass/cover.
I bought this phone on a whim that I could repair it.....money well spent
Ah! it was a project phone. Congratulations!
Indeed, was advertised as "water damaged", but as soon as I seen that it would show the battery charging animation..... I knew there was potential.....Now I guess its time to lay my G2 to rest (IMO one of the best phones of the recent-gen years)
Hi everyone, not sure if this is the right place to ask this question but here it goes. But an old s5 for about 60 bucks. It had the screen pretty damaged but the LCD worked fine. So since I like to tinker with things, I decided to see if I could fix it. I bought an inexpensive lcd separator, bought me some LOCA glue. I was able to separate the glass from the lcd without any apparent damage......err ....so to speak....I assembled the phone back. When I plug in the phone to a charger, I can see all the appropriate LCD lights. The screen shows the battery icon that shows up when a phone is charging. But the pressing the power button does nothing. I am pretty much stumped. I took everything apart to make sure things were connected right but I am not sure where to go with this...can anyone provide any advice?
PS. taking the glass off with the lcd separator (which is basically a hot plate) and a wire was really efficient. and a lot easier than trying to separate the glass with a guitar pick
I also bought a 10 dollar new glass for the phone...first time trying loca glue and I am proud to say that I had no air bubbles
It's my understanding that the ribbon cables behind the screen are extremely delicate and easy to damage. It is possible that you inadvertently damaged or severed them while removing the broken screen.
Try this link below, if you haven't already, and look through the steps to see if you may have missed something.

thanks guys, if it is a problem with the power button, I have purchased the back tray which houses the power button. Maybe that will work.
I might have a method. Assuming the home and volume buttons still work, you can hold volume down and home and then plug the device into a computer or any power supply that charges it. This will then open up download mode. The power cord will be acting as the power button here. Once there, press volume down to cancel and then it should reboot your phone to the OS.
So for some reason my power button stopped working. I took the phone apart and saw that the ribbon circuit cable connecting the powerbutton to the contact pads has tore in half. I already am in the process of getting that fixed but in the meantime I want to "short" the phone power button connection to turn it on. I'm just not sure where to put the paperclip/foil/wire etc. Where exactly on the phone can I short the connection and how?
I know this is litlery over a year old, but did you figure out how to do it?
Well you could tell which pins to short by looking at where the power button connects from the mid-frame to the logic board, there is a spot with 4 contact pins, you short two of them to turn on the phone, try a combination of two until it works.
Or you could just replace the mid frame and if the springs on the logic board for power button are too low, just bend / lift them up a tiny bit.
I will try that, Do you have discord by any chance so I can message you there instead of on this post? My tag is Mailbox#4744

I have an ooold phone, a rooted Xperia E (C1504) from 2013. This is important, because I am limited to using Android 4.1.1 Jelly Bean.
Long story short, the power on button is broken. I pulled it out with pliers because it was malfunctioning to the point of making the phone unusable. I actually use a clip folded so that it touches both ends where the button was soldered and it actually works perfectly fine as a substitute "button". Thing is, it's super inconvenient. I don't wanna take off the lid then put the clip just so the screen turns on so I can change the song playing.
Anyways, is there an app that allows me to turn on/off the screen or map my power button that does NOT heavily drain my battery?
I have tried several suggestions but they either don't do what I want/do it poorly, or are not compatible with jelly bean.
Or better yet, does anyone know of any app that turns ON the screen when connecting 3.5mm earbuds? This is an already included function in many phones so I imagine there should be an app or xposed module that can do that withouth relying on a wakelock running 24/7 draining battery.
Basically I want something that does what "Volume Power" does, the problem with this god tier app is that it drained half my battery on 5 hours of stand-by. It's a shame because it's exactly what I want.
Anyone has any ideas? Thank you
PS. as a side note, if you want to answer, I figured I'd rather ask here than making a thread for something like this.
I have an xperia arc s with a broken screen. If I lift it up of the case in a manner that the flex cables are tense, it works ok with many ghost touches. As soon as I remove what was under it holding it high above the phone case so that it sits normally, the image fades away. Backlight still works, but the image goes away. Only until I pull it up and tense the flex cable is that the image returns. I know the screen is shot, but still, I'm curious, any ideas what happened with it? lol
EDIT. PS.2. Well the problem with the screen I mentioned is that the flex cable was more sensitive than I was accustomed and I damaged, that's about it.
EDIT.
I did find something, and while it may not be a solution for everyone, it was almost exactly what I wanted. First I rooted, then I used Xposed Installer and used Xposed Additions so to be able to map the physical camera button and add "Screen Off" and "Screen On" conditions to it.
The only problem with it is that with a long press instead of showing the power menu (power off, restart) it just opens the camera, as it's supposed to.
I guess you could solve that but it doesn't matter in my case, since the power button switch is soldered directly into my phone's motherboard rather than being a flex cable addition or something, so I just removed the button with pliers and use a sanded paper clip to make a connection between the 2 points where the button was soldered, that way I bring up the power menu and also turn on the phone.
Again, this worked for me because of the way the power button was put on my motherboard and I did this only because the button was completely shot and unusable, like a ruptured appendix. It was turning off and on my phone, also preventing it from turning on and all of this completely at random. If your power button is a flex cable accessory that connects to the main board or is not completely shot like mine, don't do this because it will help nothing, hey, in your case it's probably better because you just replace the power button + volume buttons flex cable for another and you're good to go. You can get it from ebay or buy a 2nd hand phone that is not working (which should be cheap) and use the spares for your own.
Hope this helped someone, someday, anytime.
