A friend of mine has a 2013 Nexus 7 and claims they spilled water on it, and the power/lock and volume keys would not work. I opened it up and removed the volume/power flex cable from the zif socket, and tried letting the tablet sit in some rice, and the volumes keys will now work, but the power/lock button still does nothing.
My question is, if I get a new volume/power flex cable, do you think it will solve the issue, or is it more likely that the problem exists in the zif socket or circuit board?
Maybe it shorted, in that case new flex cable wouldn't help..

Since about 2 weeks my phone had a problem with its micro-usb port, because it was thinking that it was charging without even a usb cable in it. I searched the forum and found out that i should replace the micro usb ribbon cable. Well today i did that and the charging problem is solved.
But when i was disassembling my phone i accidently broke the volume button flex cable . And now my volume buttons dont work any more, i went to ebay and bought the volume ribbon cable for my nexus and i will get it around next week. But does anyone know if its just like the micro-usb ribbon cable that you just have to click it in? Or does it have to be soldered? Because if it has to be soldered i have a big problem because i have no clue of how to do that :s.
Thanks in advance
My phone is a GSM (i9250) version by the way.
If you have the GSM version, it's just a cable you "click in", however on the CDMA versions, the volume buttons are soldered to the motherboard.

I found an immage on the internet and it is of the GSM version but i can't post url's .
it looks on that pic as if it is soldered on, it has 3 metal pins on the cable. so my guess its soldered on then, no? or can you please show me a gsm version pic where you can tell me if its soldered on or just clicked in
Sorry to rain on your parade brother, the volume flex ribbon cable absolutely needs soldered on, the POWER button flex cable however does not. Simply undo the little black clip and pullout the old ribbon, slide the new power button flex cable in and flip the plastic clip back down and you're good to go. I know this because I just replaced both on my phone.
In the attached image, look near the red outlined box toward the top, it's the RFMD RF6260 quadband 2g/3g/4g power amplifier module (again, outlined in red), you'll see the longer skinny flex cable with double sided sticky tape. Look closely, that bastard is soldered on there, 3 pins.

Which solder kit did you order?
I have to replace my volume ribbon cable. I have the replacement. I need to buy a solder gun.
What should I do?
There's no way I can afford a new motherboard, and it seems impossible to remove the power button flex for replacement without instructions, re-attaching a new one would be fairly easy I imagine, but I desperately need help for this one.
Are you absolutely sure you've broken it? Did you fix it? I have seen a couple devices where the flex cable pops out of its connector (especially if you go disassembling the device) but ever so slightly that the power button works only sporadically. The fix seems to be to reconnect the flex cable and the power button starts working.
torn power cable!!

I have replaced smashed screens and uodated the battery, then after I needed to hotwire the battery so I could finish flashing a ROM, I have carelessly managed to slightly tear the power ribbon up near the switch button. GRRRRR
I am about to attempt to drop a slither of solder across a slit I'll make with an exacto knife and see if I can get anything. It will power on as I added a switch in the NiMH battery pack I made up and was surprised that I couldn't make any selections while I was doing stuff in the bootloader functions. Bugger. I mabaged to relock the bootloader as I was going stock for something, then after power drain (I now realise that it doesn't charge your phone while in the bootloader screen) and now with a re-locked bootloader, I cannot select 'yes' to unlock the bootloader again suggestions? ...meanwhile, I'm about to probably waste my time attempting McGyver ribbon cable surgury.
I did actually manage to repair a ribbon cable using enamelled wire (30 awg) and a microscope but eventually just replaced the cable.
I bought a cable similar to the one you want for approx £5 which arrived 2 days later.
The on off switch and the other end are just held on with 2 sided tape, so will gently peel off by prying beneath them. I did think the other end would not come off.
My advice replace the cable.
Hello. Does anybody know the location of the power managment ic? I have an issue, when connected to charger, it will charge for a split second then stop, then start again. Never charging. It is not the port, as I can move the cable around, and it will not affect the charging.
I have seem the power port, and it has some ic's on it, but I am not sure if one is the power management ic. If it is changing the port should work.

When you plug the cable into the phone does it sit in the hole tightly or can you wiggle it a bit?
If it wiggles you have something like lint stuck in the port. Power off your phone and dig around in the port with a sewing needle to remove the obstruction.
I have opened the phone, damaged a corner of the screen in the process, and found that it is the connector that goes from the power port to the main board. If I apply pressure it will charge without blinking. I have ordered a new power port board, and sadly now I have to find a new lcd.
Hello guys,
I have replaced my battery today, but it seems as I was struggling to remove the glue I have ripped the side buttons ribbon cable a little, therefore the power button is not working and I can't power on the device.
When I plug it in a computer, I can see it charging. In device manager it is showing up as DVD Device - HTC Android Phone USB Device and as a USB Mass Storage Device. I have tried fastboot and adb and they are not responding.
I only want to power on the device, so I can use it, because for a new cable to arrive it will take like two months.
Any help is appreciated.
Thank you in advance.
EDIT: This is the part where it got ripped.
As I was looking for a cable from ebay, I noticed something. The cable there on the bending has only one track!
The first thing I immediately tried was touching the two parts of the cable to try to reconnect it, so I can at least power the phone on, but it didn't work.
What I was also thinking is to put some kind of conductor between the rippage, but I thought there were more than one path on the circuit and that I can put electricity where I don't want it.
Now, looking at this one circuit path do you think putting a solder wire in between could transfer the power up signal? Or is it not a good idea? Is it possible that there are more connections inside beside that track?
P.S: I am not a very good electrician, I have soldered some pins, but I really have no deep knowledge in that area.
EDIT: I have fixed this by buying a new module from ebay and replacing it.
Okay yes hi, I was changing the battery of my tablet recently, and when I gently flipped up the ribbon connector tab up to remove the ribbon, the tab broke off and now I can't get it back on, and one of the little golden connector thingies seems to be gone.
I tried as hard as I could to reattach it but seeing as I have no idea how it even connects, I wasn't able to.
So what I did was I slid the ribbon in place and taped it down.
Now everything works fine, except for the home button. It's completely unresponsive.
Can anyone help me out here? Is it because the tabs missing? Is it not being held on good enough? Or could it be because of the missing gold thingy?
