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.

Hello,
I recently changed the LCD and Digitizer screen of my HD2, but while disassembling it I half cut the flex cable for the buttons, while trying to take it out. It's not completely cut, its about 1 mm cut, but non of the buttons are working. Is there a way to fix that without replacing it, or i have to replace it and is there different type of buttons cables for the EU and US versions, and will this work http://www.ebay.com/itm/New-Keypad-...887?pt=LH_DefaultDomain_0&hash=item43af09e827
Thank you!
Not so good news

You have no other choice than replacing it...
There are no differences for keypad flex between EU/US version.
You *could* scratch the enamel and reveal the tracings underneath, and then bridge the gap with solder, and then wrap it with thermal tape or similar..
I have never had that happen to me during all the times I had to disassemble my hd2s to replace the digitizer but this is what I would have done.

Yeah, you could do this, but then you should prepair yourself to disassemble your device sooner than you've been expected!
In other words I wouldn't recommend this to someone who doesn't disassemble his hd2 every month(even week)!
Just bought a new screen for a cracked hd2 and hit some problems. Firstly, its a uk hd2, so it was a solder connection, i bought the screen + digi from ebay and noticed it was a ribbon connection (not sure if that will make a difference). When undoing these plastic clips
http://imgur.com/Faiyig3
Both broke. They were so brittle, has anybody seen/heard of a way to fix this? I put it all back together and the screen does come on, but touch doesnt work.
Can anybody tell me what these cables do? Is one for touch, what about the other?
Gutted about my hd2, its been going so well all these years...is it fixable?
Not good :-/
those 2 clips: one is the flex ribbon connector & other is the LCD ribbon connector.
The ribbon from LCD also is feed for digitizer.
Not sure if the locking arms are replaceable by themselves ! will look at an old mainboard & see.
you may get some function by bending a very light V in the ribbon so point of v is ribbon contact face & thus pushes tighter in socket promoting better contact.
putting a bit of tape on back may help too! be careful though as actual socket is very fragile too ...

Tell me about it, thanks for explaining what the ribbon connectors do...I couldn't understand why the screen would turn on if the connector was broke. That's a good idea about slightly bending the cable, I will try that tomorrow afternoon. If i could swap them out, that would be awesome.
Thanks for answering, I appreciate you talking time to help a fellow hd2 fan!
Have made none working digitizer work via creating very light v shape bend in middle of contact area (bending across width of cable)
Do be gentle though ... not sure how successful it will be without clamp though :-/

how did they break? i'm going to attempt this myself soon and would appreciate any advice on getting the clips open safely.
Just replaced the glass on my s4. I have never done it and put way too much glue on. Most of it seeped out the sides but it got down into the home button and capacitive buttons and also up in the top of the digitizer(the digitizer cable). The phone is completely apart and board/camera/proximity sensor is gone from phone. Will the home button or digizer​ eventually stop working? Read a thread online that said they will corrode but don't think that's right. How should I get the excess glue dry or out of the phone. Thanks for the help.
Maybe heating the glue will make it liquid again and you can wipe off the excess.

I don't think that will work. I did not remove the digitizer to put the glass on. The digitizer is in the phone and only way to remove it is to take the glass off again.
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...

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.
