At the end it shows you to heat up the digitizer to losen the adhesive that is holding it in place all around the edge. After that, slowly pry around. Do it really slowly though and let it work itself off, and don't use a sharp object because it will damage the sensitivity of the digitizer. Really patience is key. Don't rush it like I tried to the first time also be careful of the lcd underneath.

Just to reiterate what was already said, pry very gently, don't stick whatever pry tool you are using too far into the device, the LCD below will crack so easily. I did it when I did mine. Have patience, take a lot of time slowly working it off the adhesive little bit by little bit. There isn't any magic trick to this, it takes a lot of time and practice.

[Q] Replacing Gorilla Glass Adhesive

Hi All, I'm one of the few who faced the problem where one side of the screen is slightly lifted on the edge. It doesn't cause any functional problems, but the springy feel is annoying. It's probably the adhesive on the left acting up and not sticking well. Press the screen down, and it will uplift within minutes. Tried the hot air method to melt the glue slightly, but no use.
So I probably want to replace the adhesive, and began looking for teardown guides.
None, however, really shows if the Gorilla glass can be pried off from the top ,leaving the rear un-dismantled. The flex cable should goes to the mainboard at the back, but I don't need to disconnect that for this purpose. I'm also not sure if I should pry the top or bottom.
If anyone has done it before, kindly share your experience here.
Thanks
Full replacement seems like the best idea.

oh. Why so? Seems like an overkill proposal...
I have the same exact dilemma. I see this is an old post, but maybe someone else can chime in. I really don't want to dismantle an otherwise working phone just to reapply adhesive. I like the phone but this seems like a really poor design.
Anyway, if anyone knows of a way I can reapply the adhesive without total dis-assembly I'd love to hear it!

sorry you cant, im replacing the digitizer for mine and u cant take off the glass without ripping off the flex cable for the digitizer.
i suppose u can heat up the adhesive and carefully open it alittle bit and put some glue on that corner. i say glue because you probably wont have room to put double sided tape and remove the second backing without tearing the flex cable for the digitizer.

[Q] disassemble or screen replacement guide

Do anyone has video or pdf or wtever guide to give the instruction how to disassemble the flyer?(i am thinking to repair the flyer myself) Thank you
Here you go:

Yes, there is a note in the techrepublic teardown about it being bonded like a smartphone. You should however be vary careful given the size of the screen more heat (not temperature) is required, and the risk of thermally cracking the underlying LCD panel is correspondingly higher.
Beware! Learn from my adventures.
So, I took apart my wife's HTC Flyer this past week to replace the screen. While the Techrepublic teardown shots are helpful, it's missing about ten steps at the end that involve actually removing the screen. I've messed around with tabletpc's and laptops before but not cell phones so wasn't really prepared for the fact that you have to pretty much take the whole Flyer apart in order to be able to get the screen off. As far as I can tell, no one else has documented taking one of these apart to replace the screen. I will write up something more involved when I get a chance but here's a couple things that I found out about the screen.
1. The part of the screen that you touch with your finger and stylus is not glass! It is a heavy plastic layer that is adhered to the glass digitizer. It is clear with the black around the edge and cutout for the HTC logo. This was the part of my screen that had chips in it. I tried to use a screen repair kit to repair the chips (which I did) but it took off the outer, darker finish in the process. So I moved to the next step, replacing the screen. I didn't know about the outer layer, otherwise that would have been much easier to replace. But, I don't think you can get that part unless you have connections with HTC.
2. The outer layer/digitizer glass comes as one part (along with the n-trig connector). I ordered mine for around $50 on ebay.
3. You will need to take the back off and much of the motherboard to be able to disconnect the n-trig connector.
4. Taking the screen off will take heat. I used a hair dryer but more heat could be better although you have to be careful of the lcd underneath. My digitizer broke while removing and ending up putting a small gouge in the lcd. I was able to fix the lcd well enough, just be careful.
5. HTC used a buttload of sticky tape to secure the glass to the lcd and case. My cheap blue pry tool quickly broke so I ended up using a plastic butter knife to separate digitizer from the case. Once off, I used Goo Be Gone to get rid of all the sticky tape from it. I'm ready to put new tape on but I'm not sure exactly what they used. Anyone have any ideas? It's a black, closed cell sticky tape that is really stringy when it comes to taking off. Most of the stuff I see for sale online seems to be really thin stuff. I picked up some Scotch Outdoor Mounting Tape by 3M that looks to be similar that I am going to experiment with. Anyone know for sure what they used?
6. I put the new digitizer on temporarily to check to see if it worked and it did (yay)! But I still need need to cut all of the tape and put it in the right spot. There are also these little plastic tabs that go on the backside of the screen. They are used to refract light from the led's to light up the outside navigation buttons. Be careful not to lose these. I did, and had to make one. We'll see how I did once I get it back together.
7. I found that there's not a lot of parts out there for these things. At least not compared to cell phones. Now that they're being discontinued, I don't know if that is going to help.
Anyway, I took a few pics along the way and will try to write something up when I get more time. I just wanted to give folks a heads-up on the screen and how it's put together. I can't imagine the View's screen is any different. So whatever they're using for the outer layer isn't Gorilla Glass. Or is it?
UPDATE:
Here are the promised photos of this disaster. I'll add the commentary tomorrow (I'm tired).
Two more comments and I can finally upload my photos.
I need to replace my LCD and Glass...anyone know where I can order these parts...I cant find them anywhere.
Hard to find parts for the Flyer/View which could be a problem. Looks like some is selling an LCD, though on eBay.

Much better price. What kind of tape did you use? Also did you have to replace any of the light reflacting plastic tabs that are used to light the buttons around the outside of the digitizer?

Will a replacement screen for the Flyer work well on a View?
I don't see why not. Except for some of the internals, they are pretty much identical hardware wise.

[Q] Questions about screen replacement

Hi xda community,
I had just broken my screen and started finding for a replacement. And i have found two nice items at EBAY:
First one
Second one
First one doest have FRAME. So, the question actualy is: what is the best choice? As i undestand, you should have difficult work with only screen replacement (first link). Item from second link have only frame, so i should transplantate other parts from my current screen module, which (parts) can be very small and difficult to install.
I need you suggestion about what variant is better for reparing phone yourself.
Thank in advance
For the same price, I would definitely use the one that has a frame.
As far as I know, it is possible to replace the screen only. but because the screen is taped to the frame, you would need to break (as in litterally break) the screen and take out the shreds and then try to replace it with the new one. there should be guides on google/youtube/xda. should not be to difficult, however, I would first do some research on what you could do wrong/mess up before deciding what to do.
I replaced mine with one that included a frame. it is quite easy to replace, and almost idiot-proof. This thread will help you. Just do not scratch around on the board with the screwdriver and do try not to touch any metal components with your fingers. You need about 20 min of time and a screwdriver that goes with the screws under the batery cover.

hope it helps

thank for you answer, but if you watch my second link better you can see that with frame variant doesn't have any sensors,wires,boards-it's not a full module as on xda thread which you provided.so i need replace them from my phone, what is difficult.
yes, I did not see that. it has the cables for the screen and the touch buttons, though. and it is not dificult to move the small parts. I had to move the sensors, front camera and the lower board (where the usb and one antenna fixture is) from the old to the new screen. they are held in place by double-sided sticky tape. if you are careful you can just pull at the cables gently and push them out with a toothpick or something like that.
in the end it is a question of preferences, if you rather change the front side or the backside of the frame... but I still think moving the things in the back is easier...
Hi everyone,
I have some question about screen replacement myself.
My dad just dropped his note 2 and damaged the screen (really unfortunate, it was really a little drop!), so I was looking into buying a screen from eBay and replace it myself. yes, it's tricky, but not all that much imo (big +1 to the guy from the YT channel LE55ONS, his videos about this kind of stuff are amazingly well done).
So, the screen is broken, the display is not, but if I bring the phone to the rapair guy he will almost certainly replace the screen and the display for €200+
If I buy something like this
http://www.ebay.com/sch/i.html?_trk...=note+2+replacement+screen&_sacat=0&_from=R40
and replace it myself I can do the whole thing and spend some €50 tops.
I was thinking about this one
http://www.ebay.com/itm/Gray-Front-...093?pt=LH_DefaultDomain_0&hash=item3a7dc376c5
Here come the questions. Can anyone point me towards a good screen replacement for something around $20/30?
Are these Gorilla Glass 2? Is the quality good?
Also, seems like these don't have any connectors, the original one has 2. I can always use the connectors from the old screen, but if someone knows about a screen with connectors included, can they please let me know?
Thank you everyone

Shoot, I'm sorry... I tried several search to see if there was a topic about this, I couldn't find one and was already opening a new thread when I saw this among the suggested one... I overlooked the title, thought it was about the note 2. Again, I'm sorry, my mistake.
It doesnt matter.But I reckon theres a 95% chance youll break the lcd.There was a guy posting all over the place that he managed to do it.
Its up to you if you want to risk it.

Is there any way to fix a flex cable?

I was trying to replace my digitizer when I accidentally broke the flex cable, and now the touch screen doesn't work at all. I'm completely broke and unemployed so I can't afford a new digitizer, and I also need the phone working in order to get a job. So, can the flex cable get fixed by using either glue or something hot to attach both pieces together? Has anyone tried it before and succeded?
Thanks.
I'm afraid you're out of luck on the digitizer. Sorry.
It's not just a matter of sticking two pieces together, it's much more complicated than that. There are tiny electrical leads in there too which need to be connected to the appropriate spots on the digitizer. Even if you manage to hit those points, how will you keep it in place like that? You use glue and you've ruined the whole thing. In the factory they use tiny amounts of special glue that is then heat-treated to stick to the exact positions on the digitizer. Overall, the whole thing is way too intricate to be fixable at home. That's why nobody even tried it as far as I know.
Maybe you could try asking for donations?

LCD+Digitizer Replacement Tips

UPDATE: So, the digitizer I bought developed a massive dead zone. I already contacted the amazon store I bought it from, they're replacing it for me. Why does this matter? Because now I get to update this post with pictures/video! So, yeah, I guess this guide should get a lot more helpful soon.
Update 2: Ok, so, I don't even know how to express my anger and frustration. This girl at work shoved my phone out of my hands and into the leg of a table, completely destroying my phone. So, yeah, sorry, I guess I won't be updating with pictures/video, because the amazon store isn't going to take the screen back now.
Yo, guys. If anyone noticed that I was gone, I'm flattered, since I don't post a lot. But yeah, I havent had my Optimus G in about a month, so I havent been on this forum. In that time, I went through my Second Motorola Atrix HD, a broken Galaxy S3, and even lived through Google Voice on my computer. It's an extremely long story, and kind of ridiculous, so I'll spare the details.
HOWEVER, I did finally just buy a replacement Digitizer and LCD screen, and successfully installed it, and I want to share tips for anyone doing it themselves.
When removing the back, after you've removed torx screws, start prying the back off from in between where the Sim card and MicroSD go. Where the back of the phone and the chassis of the phone are separate is much more obvious in that cavity, PLUS dents/dings from jamming a screwdriver in there wont be noticeable when you put the bay cover back on.
Don't force anything off. Make sure you've removed every screw, unclipped every clip, and removed ribbons from everything you're trying to take off.
Removing the battery is tricky. Be careful not to deform it too much, cause that's dangerous. But there are 2 strips of double sided tape running horizontally beneath the battery. Try to get something between the top one and the battery, then carefully pull the battery off the second strip with your hands. sticking too much stuff beneath it to pry it up is going to cause some trouble, so lifting it with your fingers might be better.
Remove the motherboard. detatch all the ribbons, antennae, everything, then pull up from the left, then slide left and out. This is how I got it out with the least resistance, but there is no science to it. If you've gotten this far, you can figure out how to pull it out without breaking it in half.
Components that need to be removed before LCD+Digitizer removal:
Motherboard
Battery
Camera
Just put them off to the side, you don't want them damaged during the next part.
WARNING! If you plan on saving your LCD screen, DO NOT DO THIS. The high heat will cook your screen and make it unusable. Only do this to remove a broken or unsavable Digitizer+LCD.
Alright, now pull out the heat gun. Alternatively, you can do what I did, and use a hair dryer. Not even kidding, this will work fine, and will be hilarious when you tell your friends about it.
On a high heat, start heating the screen. If you're using a heat gun, just do your thing, you know how it works. Hair dryer folks, keep the dryer very low to the phone, low enough to feel the dryer being pushed up by the air, holding it just high enough so it sort of hovers. (You'll know what I mean when you try it. If you don't, just keep it about half an inch off the phone.) Move the dryer along the edges of the screen, all the way around, thats where the glue is. It should heat up pretty fast.
Using your pry tool, start at the speaker grill and pry all the way around the phone. lifting just slightly upwards. If it's not extremely easy, apply more heat. Work all the way around, then pull the screen off. Be careful, it's likely you'll shatter the screen even more at this part if you're not careful. User Bozwell had an excellent suggestion (post 4), cover your screen in tape, then begin separating the screen to keep from getting glass everywhere. Great idea, Boz!
Alright, so from here on out, it's just reassembling your phone correctly. Piece o cake.
Firstly, put your new screen in. If it came with adhesive, it's up to you if you want to apply it now. I'd think you probably have to, but up to you.
If you're like me, and no adhesive was provided, hold off on doing anything for now. Just put the screen in the hole, and thread the ribbons through.
The motherboard lines up with some contacts on the chassis in a few places, but most importantly, there is a connection on the top left corner of the body, and the UNDERSIDE of the motherboard that needs to be made. I believe it's proximity sensor, but not sure. It's very difficult to tell if its attached, but look at what I'm describing, and try your best to mate them.
Don't forget ANY cables. Like, that's pretty obvious, but even when you're sure you didnt forget any, check again. The camera's ribbon is underneath the screen's, don't forget that one. I reassebled the whole thing, everything was working perfectly, except I no longer had any mobile connection. I couldn't imagine what I'd broken, since that's a whole different area, but going to phone status and checking my signal strength revealed I forgot to reconnect the white antennae (status showed my signal at -200,000 dbm). So, double check, because the more often you have to reopen your phone, the more flimsy it's going to get.
Alright, screw the plastic shielding back on, reconnect your battery, then flip the phone to be face up. Power it on, test the screen to make sure it's functional. If all is well, power off and glue the screen in. What I did, and I welcome anyone to tell me a better glue type or method, is plain ol Super glue along all the edges where the old glue was. Press it in, flip it over, and while it's drying, finish reassembling the phone (should just be make sure everything is screwed in inside, then put back glass back on.
If your screen wasn't functional, I guess try to get it replaced by whoever you bought it from, and leave your phone disassembled for when it gets to your house.
Alright, that's pretty much the thick and thin of it, it genuinely isn't that hard of a replacement. I've done a number of digitizer/lcd replacements, not bad at all. I hope this helped anyone stuck or wondering about anything. This video can be used as a rough example, but it goes really fast.
Good Luck!
replacement of lcd/digitzer
the removal was a nightmare for me. It was hilarious when the glass cracked it was exploding into a million little bitty pieces. I didnt use much heat, and there lied my problem. But yeah mine cracked in a way that it was completely unresponsive.

Haha that's crazy, it bothers me how fragile this phone seems to be.
To keep the glass shards from going everywhere try covering the screen in tape before you start.

Great idea, OP updated!
So, what would I do if the screen itself is ok and it's just the glass (and digitizer) that is broken?

You'll need a real heat gun, I think. You'll have to find a heat just hot enough to soften the glue, but not cook your lcd. Hair dryer method might work if you are extremely careful and very quick, but not sure exactly what the best method would be. Sorry

I figured...though I've been eye-ing using the screen+digitizer+front housing if and when they get back into stock.
(digitizer only is also out-of-stock)
