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.

I have looked high and low for Legend disassembly instructions in order to replace my screen (Digitizer) I finally found instructions on how to disassemble the HTC Legend and replace the screen thanks to allerien's post in the XDA forums 11th March 2011, 07:17 PM. There are no YouTube videos yet that I know of that actually show u how to remove and replace the screen so this is a step by step guide tat will help alot of user's including me.
Thanks Allerien

I fixed my Legend
I cracked the display of my legend and purchased a new one on eBay (roughly 40 pounds) - obviously delivered from Hong Kong but a genuine Samsung (in case you didn't know the Legen's screen as well as most of the AMOLED screens are Samsung's).
Then I used the above information plus some YouTube videos to give myself an idea as to what should I do. The result follows:
I used a hair dryer to heat up the back of the phone (camera and loudspeaker cover). Perhaps I should have been more patient as in the end I decided to use a knife with a very thin blade to lift it and I scratched the plastic and the aluminium body a bit. Anyways - the back clicks in but is glued in addition to that so you have to use both the heat and gently applied force.
Once you remove the back cover (which took me the longest out of everything) you should start removing screws. There's two behind the back cover and six behind the bottom cover (where the battery is). At this stage you don't have to remove all the screws - the bottom two, the one behind the IMEI and the one under the VOID sticker hold the main board but the two screws sitting deeper inside the phone's body hold the front buttons so you may leave them for now.
Now comes the trickiest part so read carefully: the main board is held inside the unibody by the screws (which we already removed), but is also glued right below the camera lens and along the sides. You should probably heat it up as much as you can and for a long time. I decided to do it the hard way. My dislplay was already cracked and it's the most delicate part of the phone so I said "whatever" and used the same knife as before - moved it alongside the screen (pushed it in gently from the front) until there was no resistance (the glue let go). Then I pushed and I heated the thing up and pushed and tried from every angle until finally the board slid out of the unibody. I hope you'll find it easier then I did as it seems that everyone describing it found it quite doable.
Now everything becomes easy-peasy. Remove the remaining screws to put the buttons aside (you'll have both the actul buttons and the tiny board with sensors - the latter sticks to the screen but once you remove the connectors, yu can take it off too). All the connectors are quite easy to remove if you hav a needle or something (just pull them out gently). I didn't worry about noting which is which as ther is practically no way you can mix them up - they're very different.
The rubbery plastic black surrounding of the board clicks in, so once you find the right spots you can lift them gently and take the thing off. You'll be left with the display covered by the shielding from the top and a thin metal board from the bottom. You have to remove two more screws to disconnect the main display plug.
And the final bit (that's where the thread's author had a problem I believe). My display was cracked but the shielding - fine. These two are glued together so I had to find some space for my finger nail and lift the shield. By slowly and gently pulling it apart I detached one from the other - and had to do the same thing with the metal board. Don't forget there's some extra stuff to remove from the back of the display - they're all glued but the glue will remain fresh enough for you to glue them again - this time to the new screen. The same applies to the front shield. I hope you won't let any dust sit on it in the meantime. You should have a screen protector on your new display if you bought it like I did. Remove it now and the display will be happy to stick to the old front shield just as if it was always there. The metal back will also fit in.
Now you can go through the above process backwards - just remember to connect all the connectors.
What I didn't do: I didn't use ANY glue putting the phone back together. As an effect the front shield is sticking out a bit (doesn't sit in the unibody tightly). It doesn't affect the phone itself but it gives you the funny feeling that something isn't 100% right. But I prefer that than screwing something up with a misuse of glue (glue can be disobedient).
The most important piece of information: the phone is working 100% correctly as if it was never disassembled by an amateur. Apart from two scatches on the back, the VOID sticker missing, the front sticking out slightly (less than a mm) and the missing battery slider (which I forgot to put back in and didn't bother to repeat the whole process for the sake of it) - there is nothing wrong with the phone. So if you ever crack you ever crack your Legend's screen - you can try fixing it yourself if you have the courage.
Isn't it possible to just exchange the glass along with with the digitizer? I myself need to replace the digitizer, because mine went quite unusable after an accident with water..
Either way this was a nice guide which i will make use of!
great info my legend has only a broken digitizer so i will be replacing that soon
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!
I was cleaning the dust out from behind my screen and I disconnected the cable that is glued to the top of the touchscreen. I put it back in place (as best as I could) and let the glue set, but my touch still doesn't work.
Is this something I can fix with better alignment (and maybe a little bit of conductive glue) or do I need a new digitizer?
Has anyone else done this?
where was the cable actually plugged into? I am assuming you just have to put that in and shut the rubber clip (I apologize to the community for my lack of technical terms) but can be a bit difficult depending on what tools you have
I had this happen too. I had to buy a whole new digitizer.
Damn. Thanks I guess :/ I'll find a creative use for this one. I wonder what my atrix will look like with all the paint removed <_<
It winds up plugged into the same ribbon as the speaker and front camera I think, but its on the glass end that my promblem lies. The metal fingers on the wire are glued to the ITO fingers on the glass, and I don't know how to get a proper connection back
try here and see if you can get any clues.

i don't know if it helps, but it might lead to something.
I used that guide when I first took her apart, and tellingly, they don't disconnect the screen from the frame.
Hi,
I recently changed the glass on my s4 the repair seemed sucessfull as the screen did turn on and the touch was responsive however 24 hours later the screen has gone blank but the touch is still responsive as you can hear sounds when you touch the screen. There are no visible cracks.
The method i used was a seperating machine and attached the glass with loca glue. So what can have gone wrong. Advise would be apreciated and is there anyway to get the display back on.

The glue you used could have been too liquidy and caused a short circuit. If that happened it's fried.
It's also possible that the connecting cable that powers the screen simple came loose because it wasn't put in properly. That is what you should hope for because it's a quick and easy fix.
If heat was involved in the separation or gluing process it could have damaged something that took a full day to finally fail as well.
It could just be a coincidence that it failed right after you changed the glass, but I would put that in the "Highly unlikely" category.
Your best bet is to take the unit apart and see if anything looks physically wrong. Start there.
Most likely it has shortened as i have replaced with new screen and it works. How can i stop the screen shortening again if i do a glass replacement. And is there no possible way to recover the shortened screen.

There are probably no ways to restore a screen that has shorted out. Electronics do not mix when with electrical shorts. It tends to fry things beyond repair.
hi
i want to replace the battery, i have seen several videos on youtube, but when i took the screen off, there is some metal plate under the screen attached, i dont see it in youtube videos tutorials
what i did: heated the screen and then removed the screen from the phone itself
i know the battery under the metal plate, how should i remove it?
tnx
p.s
didnt remove the back two glass plates bcs they start to crack when i try to remove
You need to remove the top and bottom back glass pieces.
There is a chance you are lifting the screen and not the frame so be careful.

Hi dude. Hope isn't too late for this reply. I replaced the battery myself. I think you understood quite wrong. You have to remove the 2 pieces of glass from the back part of the phone and take appart everything from behind. After you remove the 2 glass pieces, you gotta unscrew the screws you find (i think that are 6 or 7 don't remember) and push the motherboard with the help of the same screwdriver by inserting it into a hole. after it CAREFULLY disconnect the screen flex cable and remove the screen from the housing. After it you're completely free to remove the battery.
