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.

Hello everybody,
does anybody here see a connection between missing volume buttons(physical switches on the camera module 04w2155) and the tablet doesn't start?
As backgrund info.
Tablet is doing only short vibration when trying to power on, or when connecting to charger. When connecting charger led on the back is flashing but i don't get anything on the display or other feedback except the short vibration. I suspect also some damage with the screen, but cannot confirm. Tablet has a repair of the power button.
Thank you
You might be in APX mode, which doesn't activate the display.
Press the battery-disconnect button inside the tiny hole next to sim card slot and then try to power up your tablet.
Thanks for reply/hint.
What reset did is that for around half a minute the red led was lightning continuously, not blinking. After thag blinks again.
After research about apx mode i'm more and more certain this is my situation, it's active now.
If i connect to computer, it does recognize,search for driver and then disconnects within few seconds.
Since i see this more like a software problem could i stabilise the connection to the computer and recover informations/make backup and restore rom?
Thank you!

We are making progress!
My guess - not to answer your latest question but to the original one, is that your missing volume buttons (physically missing, yes?) very much have something to do with the tablet's current condition. To get to APX mode, the tablet must be started from cold boot with power AND volume pressed at same time (physically pressed). If your missing buttons are registering as being 'pressed' all of the time, it may be difficult to create a boot situation where you can get to your android desktop.
Could you elaborate on the missing buttons?
Please someone else chime in here - I don't even have my tablet.
Thanks for reply.doesn't matter for which question. I put together any information. Issue is getting clearer.
I got the tablet in this condition and attempt repair. Power button was down so i soldered back.
Now the thing is somebody worked before in this area and i suppose the actual powerbutton is one of the volume buttons since the work done before doesnt look professional. I suppose they destroyed the powerbutton and desoldered a volume button to resolder as powerbutton. Which possibly is the case for both volume switches. Now the two vol buttons are nowhere.
The switch has 3 pins,of which the ones at the sides have continuity when the switch is unpressed.
I suppose for boot it could require that the 2 volume switches to be present, that means it could have some continuity check through the switches, and if they are not present it cannot start.
I cannot simulate the 2 buttons because for one switch the soldering pad on the board got burned.
I am going to upload pictures in 5-6 hours when i get home.
If this proves to be somehow true i would order another brand new camera module with all 3 switches, but now i'm unsure if with new board it could start, at least for flashing/recovery.
But having it vibrating and red light flashinv i see a sign it's not yet a "unrecoverable brick"
What do you think?
Thank you

I think it is definetely a screen damage, maybe a conection cord. Try to clean/replug this cord (cant remember now where it is). This short vibration indicates, that device is begining to boot. Right after vibration Lenovo logo should apear on the screen. If it doesnt - screen is down...
About power board - no connection between power and volume buttons for sure. Power button: + is central, - is other two.
stas.green brings up a good point. If you have opened up the tablet, it is very easy to disconnect the flat ribbon cable that runs the display. When I installed my 3G card the same thing happened to me. Freaked me out but it took 30 seconds to open it back up and correctly seat the cable.

stas.green you're right. the problem is with the screen. i powered the tablet and conected to the computer. i could see the memory access the files and make a backup.
i'm going to examine where is the screen problem origin and possibly to fix it. the screen cables i checked, they fit good. any other weak point known to you?
thanks for help
My next suggestion, not to fix the screen, but to get some function back - connect the tablet to a TV via the mini-HDMI port and see if you are booting to a normal desktop. Hopefully 'External Display' is already enabled. At least you would be able to test if the touch and pen functions of your screen and confirm if they still work even though your backlighting may be broken. Shining a flashlight at an angle on the screen may make the desktop visible if the backlighting is the issue.
Good luck!
Hi there I just noticed that my phone will not turn it's screen on. Just when I press Home button or Power button them 2 touch buttons on bottom will start flashing and nothing else will happend. Even after taking battery off for few minutes and restarting phone doesn't help. After restarting phone screen will just blink for split second and then stays black! Phone was working on just few hours ago and wasn't touch since then just untill now. This is stock GT-I9505 updated with Kies few days ago. Did anybody heard about something like that before? Can't connect to Kies now as screen needs to be unlocked for this. Please help as I don't know what to do!
You could try download mode to see if you get any display there and it may also be worth checking the user accessible stuff (sim/take out sd card/check sockets for foreign objects etc) but I would start looking at getting it replaced under warranty.
cheers
Removed both sim and sd card with no joy. How to get to download mode? as I've tried all those ways:
FIRST METHOD (easiest/most common)
1) Power phone off
2) Plug USB into computer
3) Hold vol up + vol down
4) Plug USB into phone while still holding the vol up and vol down
5) Yellow /_\ (triangle, Downloading, Andy shoveling, Do not turn off Target!!! symbol)
Your now in Download mode
SECOND METHOD
1) Power phone off
2) Plug USB into Computer
3) Plug microUSB into phone
4) Hold pwr + vol up + vol down
5) When Batt icon goes away, release pwr, still holding vol up + vol down
6) Yellow /_\ (triangle, Downloading, Andy shoveling, Do not turn off Target!!! symbol)
You should now be in Download mode.
THIRD METHOD
1) Power phone off
2) Pull battery out
3) Hold vol up + vol down
4) While holding vol up + vol down, plug in USB cable into the phone
5) While still holding vol up + vol down, put battery back in
6) Yellow /_\ (triangle, Downloading, Andy shoveling, Do not turn off Target!!! symbol)
You should now be in Download mode.
and this one as well:
How to get into Download Mode (eg: for Odin)
Unplug the USB cable.
Shut down the phone.
Hold down the 'HOME' + 'VOLUME DOWN' buttons and press the 'POWER' button for about 2 seconds until a WARNING! Screen appears. Press the 'VOLUME UP' button to enter Download Mode.
To get out of Download Mode, simply press and hold the power button until the phone restarts.
Screen still stays black. I forgot to say that when turning it on it vibrates as normal and after I remove battery for 10-15 sec and put it back again and then turn phone back on screen just flick for split second but not at whole area only part of it - different part every time I try this

I think you'd rather get it repaired or replaced. It seems the display is dead.
That's what I'm afraid will have to be done. Just hard to stay without it just a week after getting it from store
Haven't you heard? Once you go black you never go back.

I had the same problem, what I did was went to youtube and try to disassembled the phone.
-Checked to make sure everything is in the right place
-Took off all of the components and leave the motherboard by itself
-Heat up the motherboard with blow dryer for sometime until it get hot (not wayy too hot)
-Put the battery back on (don't screw drive anything back yet)
-Try to power up
-To make sure it works properly, lightly flicks on to every places on the side of the phone and screen.
-Put everything back on gently and done
Reflow soldering using home tools of any kind is, at best, a crapshoot. Using an oven, as some people recommend, runs the risk of melting plastic components if you turn the heat up too much. Plus the temperatures these people recommend are too low to melt the solder completely, which is what you want in reflow work. A hair dryer is a better idea than the oven since you can direct the heat. However, a lot of the heat generated by the hair dryer doesn't actually blow onto what you're trying to fix. The hair dryer also suffers from not being able to put out sufficient heat to melt solder completely. The best of the home solutions without spending tons of money on a solder reflow station, is a heat gun. Even the most basic heat gun puts out sufficient heat to melt solder completely, plus the heat is concentrated on a small area, which is what you want. I would know, as the laptop I'm typing this on was repaired twice. The first time using the oven method, and the second time using a heat gun.
Prior to purchasing the heat gun, I had tried baking my laptop's motherboard in the oven at 385 degrees F (196 degrees C) for ten minutes. The fix worked, for about a month. The problem was that the recommended temperature was too low to melt solder. Lead-free solder, which is used in most electronics worldwide, melts around 217 degrees C (422 degrees F). While I could have tried again at the higher setting, there is a risk of the plastic components on the motherboard melting, so I had to try something else.
I considered the hair dryer, but after doing a little research determined that the hair dryer just didn't have what it takes to get the job done. I bought the heat gun instead. To reflow my laptop GPU for example, I had to make sure all components except the GPU were covered in aluminum foil. I then held the gun one inch (2.54cm) above the chip and turned it on, holding it steady. After letting the gun run for a minute I shut it off and waited twenty minutes for the board to cool.
As of now, the heat gun repair has lasted longer than the oven repair. Hopefully I can get another year out of the laptop before getting a replacement. But, regardless of how the reflow work is done, there is no guarantee as to how long the repair will actually last. For some people, it doesn't work at all. Some people may get a month or two, like I did with the oven reflow. Some lucky individuals may actually have the repair last essentially forever. But when you're out of warranty and the repair service wants to charge an arm and a leg, what do you really have to lose?
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.
I'm taking a look at my coworker's Nexus 7 (non-3G model), and it's exhibiting some peculiar symptoms. The most obvious is that the power button was jammed - I popped off the back cover and took care of that. The button has an extremely soft touch now, but it seems to work fine.
It was also booting itself up in safe mode. I figured the jammed power button was causing some weird power cycling, and the filesystem had been corrupted in some way. No sweat, just flash the 4.4.4 factory image.
Still booting in safe mode every time. If I turn it on with power + volume down, I get the usual bootloader menu, and all three hardware buttons work for navigating the menu. Then I continue past the bootloader and get into Android, and it's in safe mode, and the volume down button doesn't seem to respond (though power and volume up work).
Rebooting the device with the ribbon cable for the power/volume buttons disconnected from the motherboard still lands it in safe mode. So I'm pretty sure it's not a stuck hardware button.
For good measure, I flashed TWRP, fully formatted all the partitions, and reflashed again. Same deal. Now I'm running out of ideas. Does the N7 have some kind of auxiliary volume button inputs somewhere that are jammed/shorted, and which the bootloader doesn't look at, but Android does? This is what I see in adb logcat:
Code:
I/WindowManager( 483): SAFE MODE ENABLED (menu=-1 s=-1 dpad=-1 trackball=-1)
I can upload the whole logcat somewhere if anybody is curious/bored enough to look at it. I couldn't find any interesting errors in it, though.
Long story short my S5 got wet and I took it apart, but when I put it back together the volume keys aren't working. I'm not sure If I need to buy the midsection of this phone that houses the volume and power buttons or if I need to buy a new LCD glass. I think I may have cut the ribbon cable on the left side of the LCD screen. See the below image of how the two cables look like they should be connected but are disconnected. Every tear down and pics of this phone show these two cables being connected. Can someone please confirm if I did indeed cut this cable and if it does control the volume up and down buttons? I want to exhaust all my options before I break down and buy the midsection. If I did infact cut the cable then it will be a costly mistake. Any help would be appreciated, thanks

Im not sure if you did but for now you can download a volume widget till you can have it looked at
Sent from my SM-G900W8 using XDA Free mobile app
I wish it were that simple as I have another problem with my phone, but in order to fix that problem I need to fix the volume button problem. My phone is stuck in boot loop from getting wet. It's unrooted and I could access the screen to wipe data when the volume buttons worked, but even after trying to wipe data it would still stay in boot loop. Now, If I help the volume down, home, and power button I could access the Downloading screen. This screen will give me hope of reloading a new OS, but I can't get to this screen till I can figure out my volume button issue. I"m hoping some one can shed some light to my question above. Thanks
