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

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

For the last week or so my power button/lock button has been intermittent, sometimes having to hit it 5 times or so to get the screen to unlock. Yesterday it all of a sudden stopped working and I couldn't unlock.
I am making this post to share my fix I found for the problem. Seeing how my phone is not under warranty because I have already replaced the screen, I took to tearing it apart and seeing what's going on. Hoping I could order a new power button, unfortunately the button is soldered onto the main board. Upon taking it apart I realized I had put a little shim in between the power button and the plastic button in the housing as a "rattle fix". This is what I am thinking caused the problem, this caused me to be putting too much pressure on the power button and caused it to over time break apart the back of the actual buttons metal housing on the main board. I removed the shim and it still did not work. I was going to take the main board and heat it at a low heat in the oven in hopes to reseat solder points, but before I did that I tried using a fine pair of needle nose pliers to crimp the back housing of the button back together. Luckily this worked. Unfortunately I do not have pictures, but if someone else has the same issue you should be able to see what I'm referring to by comparing the power button to the volume buttons on the mainboard, there is a metal housing around the actual button that is soldered to the main board, it has a slit down the back side of it that allows it to spread apart. The volume keys should be tight.
THE PROBLEM: Power/Lock button stops working
THE CAUSE(assumed): Nexus 5 power/lock button rattle fix
THE FIX: Using needle nose pliers to crimp the metal backing of the power button housing good and tight.
I hope this helps others out in the future as I'm sure I wont be the only one with this problem.
Thank you!!!

Thank you thank you thank you!!!!!
Bumping this with thank yous because I went to a whole lot of other xda threads that suggested soldering on a new button or going for warranty etc. THANK YOU!!!
Super easy fix, works so well :good::good::good:
Just an FYI this worked for me for a short while, then I my power button stopped working again, I tried applying pressure with pliers again with no luck. Ended doing an RMA on my phone. Had a new one sent to me and they didn't say anything about my phone being opened up. I had even replaced the whole front half of the phone including screen, cameras, battery etc.
(sorry, just saw that there's a help forum - but I don't know to move my post, or if I can.)
I had ordered a screen / middle frame assembly and replaced everything, based on a couple youtube videos (I hadn't run across the replacement thread here at the time). It went pretty smoothly, except for the logic board screw, which I had a difficult time getting out, and more difficult getting back in. All because I was impatient - I was visiting family and away from all my tools. So I ended up using needle nose pliers to get the logic board screw back in, but after I finished, the OPO wouldn't turn on. The screen does display the initial charging animation when plugged in though, so I think it's just not getting the power button click. After opening it back up, it looks like I damaged the ribbon to the power button. - I have attached the best picture I could get.
Any ideas on what my next step should be? It's hard to tell where the apparently exposed wire is run - to the other contact? It's hard to tell if it's shorting, or what.
I would appreciate any ideas or help!
Thanks
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.
