Hello,
When i was trying to place a new screen on my moto x style i forgot a screw and part of the motherboard fell off (picture), any motherboard experts know what this component is and if the motherboard is still 'repairable'?
(The screen is working but i can't seem to boot up the phone, it also can charge)
Thanks in advance

To be accurate, it's not that the part fell off, but it pulled away from the motherboard. What you had pull away is simply a screw hole for keeping the frame attached to the motherboard. The good news is that it's apparently not connected to anything. You could use a small amount of high strength epoxy to reattach the screw hole to the board.
As for your inability to turn the device on, check your button cable and make sure you have that seated properly. The screw hole pulling from the motherboard isn't the source of that issue.

Oh, that makes sense, i've already tried replacing the button ribbon cable (with a new cable) so it isn't the button cable, i have no clue why it's not working. Anyway thanks for the info.

So I bought a new housing for my O2 XDA II Mini, during the removal of the display ribbon I broke the little black part on the display connector which holds the ribbon down, and after hours of trying to get the ribbon back in and secured I have bent the pins in the connector to buggery.
The ribbon appears to be untouched, however the connector which the display ribbon goes into is broken.
Is there anywhere I can get hold of one of these little connectors to replace my broken one, obviously very sensitive soldering will be needed to remove the old one and solder the new one in place.
Alternatively, does anyone know any mobile phone repair shops in Auckland, New Zealand who would be able to help out with my situation?
I fear all i'm going to hear back is "the motherboard needs to be replaced", however I am determined not to go through this route, as I am a poor student and the phone sounds as if it functions fine, makes the beepy noise when first starting up on the setup screen.
I was very careful with the actual screen unit while removing it, and I have had signs of life earlier on in the broken connector episode, however I can no longer get anything showing as I can't fit the cable in.
Cheers for any help.
Anything would be appreciated.
"obviously very sensitive soldering will be needed"
And that only can be done by machines/robots. I don't think humans are even able to sloder those kind of connections...
But, could you post a picture? cause I might have suggestions on how to fix it. One would be to bend back the pins on the tiny slot with a toothpick and when done to tape the flatcable, so it stays there.
I've maybe got a spare creen for you.

Hi, I've still got a SPV 500 and a MDA Compact, need to find it if you want you can have my MDA Compact screen.
Just PM if you are interested.
Is there any way to get to the buttons on the front without having to remove the main board? I just broke my cable to the buttons and I am planning on replacing it soon.
EDIT: Is there any app that will let me remap the key that is used to wake up my phone? I want to be able to use the phone while I wait for the flex cable to show up. I can turn my phone on by plugging it in because it is on MAGLDR.
No, you will have to completely disassemble the phone, including the lcd/digitizer assembly from the middle chassis to access the buttons flex.
Maybe a stupid question that also refers to this but I got conned by a guy whom I bought a HD2 from. Also the cable to the buttons is broken, as so many other things.
Does your touchscreen still react when that cable is not attached?
Yeah the touchscreen still reacts without the buttons flex cable attached, done it myself a bunch of times, so 100% confirmed

Ok thx for confirmation. This guy conned me with a 'perfect hd2' broken camera glass, broken flex cables all around, a broken digitizer, .... well nothing worth then

Darn it. Do I also have to remove the main board from the chassis too or is there any way to remove the screen and digitizer assembly from the chassis without removing the main board?
You do not have to remove the entire LCD/digitizer assembly, you just need to pry enough space between the bottom of the digitizer and the plastic frame to remove/replace the buttons. I've done it to three phones. It may be easier in the end to remove the entire thing, because it can be difficult to get the part that you pry up to adhere back together though. This phone is a major pain in the ass to work on beyond the motherboard area.

Hmm. Would heating it up a little bit make it easier to pry apart then? I tried it a bit after I realized that I broke the cable, but my device seemed to be really stiff.
And if I do remove the screen, would I need anything special to put the display back on?
Yes, you have to heat it up or you will probably destroy the phone. The best thing you can do is get it very hot (not hot enough to melt the plastic button strip) and try to get the adhesive to stay completely on the frame, then reheat it again right before you put it back together. I repair phones (and game consoles) for a living, and heating the adhesive (right) before assembly is the best piece of advice I can give anyone on just about any phone. Most of the time you don't even have to replace the adhesive if you do it this way.

Alrighty. Thanks for your help!
Hey,
i got the typical problem that my screen wasnt responding after use of endbutton. Sometimes it was working.
I now disassembled the device and saw that the flatcable had a small scratch and i guess the first one or two cables are brocken already and only get contact sometimes by luck.
So does anybody know if there is a way to repair this ?
A new touchscreen isnt to expensive 20-30€ but why throw away a working one if a cable is repairable easily?
Next time i will glue the cable to the display so that there is no flexing when pressing the endbutton. The problem is that there is a little space between that is pushed away each use of the endbutton and someday the problem occours.
Hi,
I had to replace my touch screen to solve the same issue
Is there any thing we can do to prevent the same damage to the new screen ?
Thanks
Well i tried a few times to fix the issue.
But its hard to solder the flex cable without totally burning it.
If i solder it its very likely to break fast again.
Im going to buy a new digitizer too..
To your question:
Yeah i saw that there space between the flex cable and display. The cable is bent a bit towards the buttons. When you push the button the cable is bent back in the free space.
I will glue the flex cable directly to the display and put a layer of protective tape over it. so it wont bent (What causes our error) and wont scratch(if this could happen too).
The problem is the poor quality of the flex cable. Its very hard and therefore breaks easily what causes the wires to break to sooner or later.
If i can ill try to take a few photos but its hard as my digicam cant focus so closely..
I just replaced the cracked screen on my Moto X Pure. Now there's no response visually on the screen. It seems to boot up. There's the initial vibration and I can turn on the flashlight by holding power.
I've disassembled and reassembled it several times now without a change in results. The one thing I suspect, but I'm not sure if it matters or not, is this. The socket on the motherboard for the ribbon cable going to the lcd has this black clip that you fold up to remove it. When I first folded it up, it came off. I can't get it back in. The cable seems to stay in fine, and I put a piece of tape over it for safety.
So does that black clip matter, or am I missing anything else obvious?

It seems this is more common than I thought I will post instructions here soon as to how I got it fixed
So for those who try to replace the screen on the motor x pure and damage the black clip holding the LCD flex cable in place...
1.) As soon as the black clip comes off you have damaged the phone. It is only meant to pried up with something thin like fingernails, and using a tool such as a plastic spudger will most likely break the clip.
2.) This mysterious black clip : I don't know what exactly it does but I am pretty sure it connects some of thing metal connectors, and if it is broken some of the connectors are most likely also broken, NOT GOOD.
3.) If you get no response from the screen when booting up but get a vibration, then the connectors most likely are the issue.
Right off the bat I'll say you need to find a specialized repair shop which does micro soldering. I took mine to many places first labeled as "phone repair stores" but they were unable to do anything, and the only place was a company which did micro soldering.
In my case, the repair shop had to order the part in to solder on, and they had to order from China, so I do not know how accessible the connectors are.
I hope this helps and be sure to hit the thanks button if it does help, feel free to send me a PM as well if anyone has any questions regarding this topic
Update : here are a couple of images of what this might look like

Hello
I can't charge my LG G2 D802, so I ordered a charging flex cablefrom ebay.
After replaced, the phone charges well, but the screen is almost unresponsive.
And it's very interesting, because if I replace to the old one, everything is the same, almost unresponsive screen, not like before disassembly...
Any idea what to do?
Connectors and everything looks fine, but I can't believe touch screen stop working after disassembly.
Please help if You could...
Thank You!
You disassembled the phone? If you didn't put all the components back in place as it comes from factory and taped, then there could be grounding issues. There is a set of transistors next to the lcd connector and above the charging port, make sure it's touching the golden pad on bottom and is taped.
Or else it's a bad cable, bad grounding somehow, moisture issues etc etc.
I think You're right.
The set of transistors may not connecting well.
Can I use processor pasta to glue it back?
Or just some simple tape from above?
-----------------------------------------------------------
So I cleaned it with alcohol and the original glue getting stronger, so I put it back to the right place and put some tape on it.
But still the same.
Do I have to put tape on the cables above the battery?
How could I find where is the bad grounding?

No i don't recommend to put thermal paste therez if it conductive it can short nearby components and can also get messy, it is only for using on chips. I suggest you use double sided tape, but do it strategically so that it leaves a small portion open for the golden pad to make contact. And after that you put nonconductive tape on top of that. Make sure the metal part of the white cable nearby is not touching this area, or you can also put tape between them. I suggest to put tape on the lcd connector as well.
Whenever this problem arises, and if you have trouble to fix it, an easy way is to disconnect and reconnect the battery after a few seconds, should work ok.
You can also purchase a new one like this, look for your device model - https://m.ebay.com/itm/183023879505

Seems like the set of transistors well connected now and I put tapes on it and on the screen connector as well.
And I reconnected the battery too, but nothing happened.
It's the same as before.
And if I replace the charging port flex cable to the old one, it's the same too, but before disassembly it works, but the problem was I cannot charge the phone.
Any other idea what should I do to fix it?
I cannot choose D802 on the link You gave me...
Anyway I think this one and the old one is fine if it's about the touch screen, have to be something another...
