HTC Legend Screen (Digitizor) Replacement - Legend General

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

Flimsy battery cover

Well my problem is that the plastic pin/hock that snaps the cover in place on the left side snaps loose when I push the above and lower horizontal edges of the cover....I have tried applying tape to the pin and snapin mechanism...no joy! Now I'm contemplating om sending the phone in for a new cover or new phone I really don't want to...my main concern is that I'll get a new phone with dead pixels and/or (heaven forbid!!) screen gap problem. So what would you guys do?
It should not be flimsy. It is a bit flexible thoough. You obviously have a faulty one.
If the actual phone is ok, I'd definitely hang onto it, there's enough hardware problems out there!
I'd contact HTC and ask them if they can send a replacement cover out to you first.
DIY fix on a phone this expensive? No thank you very much..

Disassembly of Legend (advises & some help required)

Hi there,
I broke my touch screen and tried to replace it by myself.
To make a long story short, I failed miserably (I broke the screen under).
However, I learned a few things I didn't met in the forum.
A- Disassembly of the case.
1- The Legend is glued. So, you have first to use hoven to melt the glue before being able to do anything useful.
15min/ 60 degree in the oven. Or use an hair dryer (I used the former).
2- Don't forget to remove ALL the screws (even the one behind the IMEI notice).
3- Don't try to open the camera lid before loosening the glue or you'll damage the aluminium body.
4- You have to unplug all the différent cables, so take notes to remember where all of them goes.
5- You must disassemble all the boards. There are 2 boards. One supporting the sim / SD connector, and one supporting the screen/touchscreen.
6- When disassembling the screen board, remove it by pulling the touchscreen at the bottom, and lift it up. don't pass a tool on the sides to remove it or worse, under the touchscreen, you'r tool will touch the screen under and break it (like I did). The screen is very, very fragile
Now, I'm stuck here because I can't remove the connector of the legent which is passed under the shield on the back of the screen.
I'm not able to remove the screen so I would like to know how to remove this shielding or get back the touchscreen connector to be able to replace it.
Once I figure out how to remove this shiled, I may be able to remove the screen too.
But now, I'm clueless (it was 2 in the morning when I gave up).
Maybe, some of you knew the trick to open this phone further.
I'd like to hear about it.
A little up to my post for the ones who did not read it till the end:
I can't remove the connector of the legend which is goind under the shield on the back of the screen.

mate it sounds like you have trashed your phone.they are built NOT to be taken apart.They require special tools and process to be repaired. The only thing i would suggest is contacting your insurance company and let them know that your phone was crushed under a car or something and then crush it under the car and you can get it replaced. If you dont have insurance, take some out and make a claim in say a month or two.
Its not an honest thing to do but your phone sounds busted and its the cheapest way of replacing that handset.
Post a pic of it if you can
Unfortunately, I have no rights to post a link or some put some pics.
Something about spam and profile that should be reviewed before being able show any pics.
This device is glued. No specialized tools are able to open it without removing it.
That would mean that the phone cannot be repaired, only replaced. My phone's motherboard was replaced, so at the service stations they should have special tools.
Fixed it!
Bottom right hand corner:
Bend the shielding back just enough to allow you to slip the connector in & then use a little glue to stick it back.
Maybe I was lucky, but my phones working as good as new again
I fixed my Legend
Guys, I know it's been a while since you talked but in case someone else is looking for this info, that's what happened to me:

I would like to see some photos too But I'm never gonna take my phone apart - can't see the point

Nice thread, i myself am wondering, if a better gsm antenna can be fixed inside the phone. and connect them to the 2 connections.
Do you have any pictures of the inside housing etc?

[Q] Digitizer replacing

Today I aquired a HTC Trophy with a cracked screen.
It was not cost effective to have it replaced by the workshop, so I'm attempting to replace it myself.
Following the MicroSD replacement guide by DominikZ, it's been a fairly simple and straight forward process, but I have now come to a point which I'm not sure how to proceed.
I've gotten to the point where I have the two ribbon cables disconnected, and have now separated the systemboard from the front. The front frame now contains the LCD, digitizer and speaker.
Does anyone have some tips on how to proceed from here?
What about the other 3 (black) screws? Torx 6?

Thanks for the tip Lance The pictures were easy to understand, especially when I don't read chinese.
However they did not cover removing the LCD and digitizer.

The three screws on the back of the lcd casing is not screws. Those are threaded cylinders, for attaching the front with the back.
Hey there
how far have you got with repairing the screen as I also acquired a HTC Trophy with a cracked screen. The phone still works so there is no rush but I need to know what I need to repair this unit?
Hey.
No progress so far. I'm not sure how the glass is attached to the front housing, but I have an idea that it might be glued on from the front.
You may be able to extract the glass from the front by using a hairdryer and something thin, like a razorblade. However I have not tried this yet, so I can't say for sure.
Good luck ;-)
There are digitizer replace videos for the htc desire:
youtube.com/watch?v=sXZqIjtFoAU
If the Trophy is build in a similar way you can see how you to remove the glass at 4:00
You can use a hair dryer instead of an oven.
Hi folks, been a long time lurker, came here after looking for a solution to this very problem, so, nlamer here's how to do it, be warned though it's not an easy repair.
(och, I cant post image links until I have made 8 posts :-S )
see attached photos, i'll prob need to do a few replies to post them all.
1:- Strip your phone down and remove the logic board from the chassis, carefully remove the lock tabs to release the ribbon for the LCD & digitizer
2:- Use a heavy duty knife ( I used a stanley blade ) to slice the adhesive holding the LCD to the digitizer, it's only held round the edges so you dont need to go too far in
3:- Peel back the cracked digi and just slice the ribbon, it's attached to the back of the LCD and your not going to be using it again anyway
4:- The LCD is held in place with the light grey adhesive strips, use a spudger to remove it, just be careful not to put too much pressure on it or you will damage the LCD, in my experience it's always better to have a replacement on standby just incase
5:- A quick check to make sure the LCD is still ok, you never know!!!
6:- On the old digi you will need to remove the three clear plastic tabs at the bottom and transfer them to the new one, these feed the LED's to the capacitive button's on the bottom, they are held in place with some adhesive & are not difficult to remove
7:- Remove all the old adhesive and apply some knew strips, I used 3M stuff here and trimmed it to fit but I dare say there are adhesive kits available on eBay
8:- Do the same to the LCD
9:- Line up the LCD with the marks on the digitizer and press it into place, the digitizer ribbon has a small piece of adhesive to attach it to the back of the LCD
10:- Place the display into the chassis, make sure the ribbons go through the gaps in the chassis and everything lines up before committing to pressing down
11:- If all goes well after re-assembly it should be looking sweet again.
Hope that helps yourself & other's out ;-)

Thanks for the instructions irepairtechstuff. It is greatly appreciated. I almost have my device wrapped up, and ready to go, but I'm having some trouble with the digitzer.
It seems behave as it pleases, and does not register pushes and swipes as it should be. Any tips on this?
Nevermind the last post.
I cleaned the connector with some alcohol, and now it works perfectly
I just got a trophy, I don't understand the adhesive verry well. I though you had to put adhesive on the underside of the touchscreen digitizer (along the edges of the screen) and on the metal frame, under the lcd or the underside of the LCD, but in this turtorial you see adhesive along the edges of the upside of the LCD?????
HELP!
Is there nobody who can help me?
Try private messaging the users who manged to get this to work. They should receive and email and might be able to come back and look at this thread.

Disconnected Touchscreen Cable

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.

Finished self-repairing my XSP

Yup, I've just finished self-repairing my Xperia SP.
Basically, I just replaced the battery. But I had originally planned -- and prepared -- to replace the LCD and the touchscreen, too. Because there seems like this "oil spot" about one-third up the bottom of the screen, and sensitivity became too low in the row where the "oil spot" was.
And I confirm: the XSP's steel frame is a beast! It practically provide the rigidity needed by all the small components, so much so that self-repairing the XSP is actually a nice experience.
The LCD is clipped onto a "carrier", which gets fixed to the frame using the two hexalobe screws on the side. The battery was attached to the back of this carrier using two strips of double-tapes, and very easy to remove (and no, you don't need to replace the double-tapes with new strips; the battery fit snugly between the LCD carrier and the PCB).
The camera & speaker are themselves on another "carrier", separate from the LCD carrier.
Here's the video I use for initial disassembly (not mine, but very helpful):
https://www.youtube.com/watch?v=WZacc3HN_bU
Here's a sort-of continuation, how to remove the LCD carrier:
https://youtu.be/oV6jEVXRJfM?t=4m04s
Anyways, after replacing the old battery (which is showing signs of degradation: Bubbles on its aluminum wrap, and an increased thickness -- old battery = 4.0mm thick, new battery = 3.5mm thick), I turned my phone on (ensuring that I haven't damaged something permanently) and... whaddaya know! The oil spot was gone, and sensitivity all over the screen is good again!
(I did lever up the LCD panel and clean its surface with a dry, clean microfiber cloth. Maybe that helped, too.)
Annnd... while at it, I replace the black back panel with a RED one
Anyways, that's a short story from me. Will update if there are any development.
EDIT: I strongly recommend you use a magnetic mat to put down the screws, like this one:
Magnetic mat on Amazon
Why? Because, not only were the screws very small, they come in wildly different sizes! Off the top of my head:
Three top back screws -- small long
Two lower-top back screws -- small short-ish
One centre screw -- very short
Two middle side screws -- very small
Two bottom screws -- slightly shorter than the top screws
PCB screws -- larger thred
LCD carrier screws -- hexalobe small
With a magnetic mat, you can "group" the similarly shaped & sized screws in a square area, and they won't mingle.
.
what sizes of philips head for 3 top screw??, I have problem unscrewing them especially top left-hand-side and top right-hand-side..Im planning to oder new set of screw driver online..But I can't identify the screw size..
Mind sharing the number on your screwdriver??
