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.

Has anyone been able to fix this? I just ordered a solder kit. 50/50 chance I'll screw this up.

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.

A few month's ago I'd ordered a LCD screen replacement for my incredible, and so when I got back from work o immediately took out the LCD from the package and started taking out my old broken. For me it was my first time experience replacing an LCD phone screen, anyways back to what I was going to say was when I unplugged the connector for the screen and the motherboard itself, after attempt to plug the connectors back together; the display connector plugged in perfect while the connector for the motherboard didn't do so well. The white piece that covers the PCB Connector, it tears a little bit off and I'd tried to power on the phone, meanwhile it didn't I tried again and things got worst. So I search online for a PCB Connector and see one, so I decided to and try to rip off the PCB Connector and plan to order the PCB Connector. So the part to attempt ripping off the PCB Connector didn't go so well, and stop there before things got worst. Any suggestions how I can replace that? I can't just leave my phone in my room and have to cover in dust. I need my phone back, how can I fix these? I know this thread seems long but I tries but it details for you guys.
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.
This person posted this about kindle fire not working
At first my Fire wouldn't charge unless it was placed in a particular way, then it stopped altogether. I pronounced it dead, and left it stowed away for a few months, but then decided to try and fix it. I think this guide may be useful for anyone who wants to fix a kindle with dead charging. Note that you may damage your kindle in the process so if you are still under warranty, use it.
1. Take off the back cover. You may need to use a guitar pick or something similar.
2. Take off the two battery leads. One has a locking mechanism which needs to be lifted before the ribbon cable can be taken out.
3. Take out all screws connected motherboard to rest of device. There are connections underneath the board so be careful when lifting it.
4. When I lifted it, I found the USB connector had broken off the entire board (if it was even attached in the first place) and this was obviously causing the problems, as the USB connector could now only connect to the motherboard if pressure was applied so that it was being held on somehow by it. To fix this, I could have tried to solder the tiny USB connections onto the board, but instead I used a different way which is working perfectly for many weeks now.
5. Get a rubber band and tie a not in it numerous times until the knot is about 3-4mm thick. Cut off remaining rubber band and superglue the knot onto the bottom side of the USB connector (the side that faces the display when assembled). Then insert the USB connector into it's little holder under the board, with the rubber band firm beneath it and replace the motherboard. Redo all the screws, reconnect any connectors you've disconnected (you may have had to disconnect some to remove/move the motherboard - always undo battery cables before you work on the innards of any device).
6. If you've done this correctly, the round rubber band knot should press the USB connector continuously on to the board. Test using your stock charger before you put it back together because the back cover is pretty hard to get off.
7. Replace the back cover and enjoy!
Notes: My rubber band knot was actually a little too large, which meant that to connect the USB plug I had to press the kindle together to insert the cable, but charging is reliable and working so far, so I'm happy about that.

And I think he's long gone it's an old post and I need help what does he mean by connect the rubber band to the usb where do you put the rubber band where do you super glue it the motherboard kindle or the usb and what does he mean by tie it how do you tie a rubber band
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..
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.
