Broken power ribbon cable - One (M9) Q&A, Help & Troubleshooting

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.

[Q] Changing Volume flex cable

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.

[Q] So I broke the power button flex cable

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.

[Q] a BRAND NEW kind of charging problem

Before everyone starts accusing me of not running a simple search, take it easy, been done. And yet, nothing to help me on the matter.
So here's the thing:
Her phone won't charge. Not when plugged into the wall, BUT when I plug her phone into the computer it is recognized and allows file transfer and everything, but just that - it still won't charge.
Here's what I've found out so far:
- Not a problem with the charger: I'm using the original charger, and it works flawlessly on my own Gnex running PA 4.4
- Nothing wrong with the battery: swap batteries between phones, my phone works fine with her battery, her phone still won't charge.
- When her phone is completely OFF and I plug it in to my PC, it plays the sound of connecting and disconnecting a device, and prompts that it doesn't recognize the USB device. If I tap the power button for a second while it's off (not holding it long enough for it to turn on), it does the same thing connecting-then-disconnecting sounds and "doesn't recognize the USB device".
So - has anyone ever run into this problem before? Know how to fix it? I know the chances are it's just a hardware malfunction, but it's weird because of the ability to transfer files- usually the problem is the reverse.
In the meantime we're using my phone as a charger for both batteries untill we get the spares and wall charger we ordered, but it's a real pain.
Just trying to find a better solution than taking apart the phone and try and fix it or just ordering a new Nexus 5 (which is tempting, but don't really have the money to spend on it...)

Its the micro USB port the pins are bent homie.
Some pins allow charging some allow data transfer. The ones for charging are damaged in your case.
Sorry to bring bad news.

Yup. Just this moment after a really really really close examination of the port and comparing it to my own phone, one tiny half a millimeter peice of metal is bent out of place and broken. Gotta order a new port ASAP and try and change it.
Thanks mate!
But hey, look at the bright side... a fun home project to immerse myself in instead of prepare for my finals! :laugh:

Back with worse news. Just replaced my wife's micro USB port on her i9250 GNex, and.... same thing. Still won't charge, computer recognizes it. Now I'm completely baffled. Thought for a moment that maybe I had been such a fool as to have put back in the old port, but unfortunately, it wasn't my stupidity.
Ideas, anyone?

P605 Several USB issues

Hi XDA community,
firstly thank you for your all your great jobs here!
I own a P605 Galaxy Note 10.1 2014. It has been "soft"-rooted (through kernel bug, without KNOXing the device) but it has probably gone out of warranty.
I experence some serious issues with any USB-related operation, let me enumerate them:
1) USB Charging: when powered off the tablet charges normally (but slowly), when powered on the tablet charges (fastly) until the screen switches off, then it stops charging.
2) USB OTG: when attatching an OTG cable, the device detect it but when attaching an USB drive nothing happens
3) USB to PC: on a Windows OS, attaching the tablet results in a "Device Descriptor" error, even with the tablet in download mode, so any firmware flashing operation is impossible. On Linux OS there's a similar error, related to device descriptors.
Obviously, when I bought it everything worked fine. Sadly, I suspect an hardware issue... I'm asking you any kind of help: tests to indentify exactly the problem and, hopefully, a solution.
P.S. I've already tried changing USB cable/USB port/PC/charger/mood/wearing/house...:crying:
Hello , i too have this problems, do you run also Lollipop 5.1.1`? Any solution found?
1) If not using the original charger/cable (or non compliant) then there's a possibility thad the data pins of the charger are not shortened. You need a charger compliant with our tablets or data-pins-shorted cable. (you can do it yourself but the cable will only be used for charging)

2) try Es file explorer (remember ntfs is not supported)
3) install kies or try

(just the usb driver)
I have exactly the same case as #1 and I fixed finally. It's because of the bad contact of the usb cable. Open the back cover (gentle and slowly prevent broke it), disconnect the usb cable from the adapter near camera, wash your hand and keep it dry, touch the golden finger one or two times with your cleaned finger, then connect it back with a little push it to the end, make sure it lock firm. ( I also use a piece 3M plastic tape to stick on the surface ). Power on and test, no problem and then close back the back cover. My machine no more that problem again. Sorry for my english not so good, and hope this can help.
With Davidmueller's Lineage and RR there is a (recurring) charging problem with usb cables. You need a cable like the one supplied, where the second GND line on the m-usb plug is not connected. The plug of the white original cable has the contact missing, i bought a recent, black Samsung cable with 5contacts,also working. None of the other cables i tried, did. The problem was there almost a year ago, got solved and re-occured during the last updates.
Results after the replace of the usb module.
As suggested by Jan&March, I tried cleaning the usb module connector on the motherboard. It solved EVERY issue for about 3 days, then they came up again. So I thought that maybe, touching and cleaning the connector, there was some bad contact on the cable. I bought a replacement part for the usb module. It has been working for about 2 weeks before showing the same issues today. I hope I'm helping someone with my experience. Any suggestions?
The pcb jack may have bad solder joints. I never had the case open, but i think the usb and display connectors belong to the components bearing most of the pressure exerted on the back cover. Except the battery and the metal shieldings on the pcb stand out more,which can only be told if you have the back cover removed.

Thanks, so what do you recommend?
That would require re-soldering. It's hard to tell, it's less likely if the connector's aren't among the most prominent parts under the back cover and won't make contact with it. I can't tell from the pics i've seen.

this just did it for me. i think the bracket that secures the ribbon cable isn't exerting enough pressure on the cable so maybe some data pins may not be in contact.

Power ic location

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.
