How to replace the digitiser - What type of glue should I use ?

I dropped my phone and need to replace the housing. It looks like the digitiser cannot be easily removed from the housing, so I bought one of these as well. Now all I have to do is move the phone from the old housing to the new and install the digitiser in the new housing.
Now it looks like the digitiser may have been glued in place. What type of glue should I use ?

More liked taped in...... I'm sure that lots of people will respond with.. Double sided 3M tape.... but if there's anything better/stronger than that on the market use it. Make sure it''s really thin tape to. I'm gonna be replacing my housing in the next month or so aswell. Goodluck.

As I also will replace mine digitizer, the newton rings are bugging me, it will be appreciable if you can share your experiences of the replacement process.
thanks in advance and god luck

Hey on more thing. I took apart my phone last night and put it back just so I know my way around when parts come in.
If your Digitizer does not work try loosening the top srews 1/4 turn. You have them on too tight.

I wasn't replacing mine so I didn't have to remove the existing one. All I had to do was attach a new digitiser to a new housing.
I was told that double sided tape was the best, so I tried that.
I used the instruction from http://www.pdacenter.ru/razborka/htc-touch-diamond2 which was easy enough.
You need to ensure you remove the micro SD card first.
Also I forgot to move the LED diffuser from the top, so I need to repeat the process at some stage.
The housing I bought had a number of issues
* The two screw point near the bottom of the housing didn't have the metal inserts with the screw threads
* There was no seal between the metal housing and the LCD screen. This could let dust in.
That's about it for a brain dump.

Hi there,
I was also tired from that oil stai and ordered a new digitizer from these guys:
http://xxx.sw-box.com/htc-touch-diamond-2-t5353-digitizer-touch-panel-screen.html
Surely it arrived in 6 days, to my horror it was a generic display,
Had some trouble removing the old one, ended up breaking it
The generic did not fit snugly, I had to sand down the edges to make them round, also had some trouble with the four buttons below getting stuck when pressing down, (shaved of some extra plastic). anyway used double sided scotch film to get the digitizer back in place.
apart from a few difficulties, it works like a charm.
Should have ordered an OEM but what's done is done
Next time I'll do the cover and get a new digitizer
Regards

I would of thought double sided tape too thick to use to stick the digitizer on.
I was thinking of using a very thin sliver of clear silicone.
Anybody tried this or have any other suggestions?
Thanks

I used a very thin layer of supergleu and it worked great!!

My digitizer came pre-glued. I didn't need any sort of glue.
http://forum.xda-developers.com/showthread.php?t=715724

Silicone is OK
I used a very thin layer of black silicone and placed a book on top of the digitizer to keep it pressed flat into the case as it dried overnight. No problems since then...
The missing metal screw inserts can simply be pulled out of the old housing ; insert screw halfway and gently pull with plyers. Carefully hammer into the new casing; insert screw 3/4, put something thin and metal on top to prevent the screwhead from getting damaged and carefully hammer into the void. Make sure it goes in straight.

I've got exactly the same issue with my new housing, no bottom screw threads and no foam for the lcd to rest on. Am trying to pull the threads out with pliers but I think the old case is going to break first or strip the threads.
This is isn't an easy job

have finally finished this epic!!!!
had to break the bottom screw threads out of the old front housing and took a good while hammering them into the new housing so I didn't break it.
used a small sliver of clear silicone to glue the digitizer in which seems to work well so far.
Have not put any foam or anything for the LCD to rest on, time will tell what effect this has.

I need to change mine as well. Where can i buy a good quality digitizer and case preferably pre-glued?
I found a few on ebay but i am not sure of the quality.
Thanks

Today i searched also for shops which have digitizers and housings. I have found 2 shops, but one of them is a german shop (http://www.mobileok.de) which does not deliver outside of germany and austria. But the other one does: http://www.sw-box.com/

what kind of glue? it's the third time that i'm re-gluing it, but dust keeps coming inside....

I guess, it is not possible to hermetical seal the housing. I had dust in my original housing too. There are a lot of small gaps everywhere not only between digitizer and frame. But it would be easy to disassemble the device from time to time, remove the dust and reassemble it again. Save your energy in the effort to make your device dust proof.

[Replacing Digitizer] Is 2mm 3M double-sided tape a must?

I have in front of me a perfectly fine HTC HD2, but the digitizer is cracked and not responding.
I ordered a TMOUS HD2 digitizer replacement, and am waiting for my T5 torx screw to come.
Beside these things, I heard that I'll also need 2mm 3M double-sided tape.
Is it possible to reuse the ones that are currently holding the cracked digitizer?
Or should I start hunting for some of those tape?

I used 4 drops of superglue when I replaced mine...

I used crazy glue but it left white residue. I cracked digitizer again so this time I will use 2mm tape, not crazy glue. I also used regular 3M tapes 1/2" wide but I had to trim it. It's a pain in the ass but doable. Now, I will buy 2mm tape instead.

Has someone a link?
Today i reopened my phone because using the old pieces of tape wasnt holding enough, so the screen was a bit over the housing.
Now i used thin tape (noname) and had to cut it myself, what really is a pain in the ass. THe problem is, that with cutting and then fingering this togehter my screen not is very stable but still to high.
If i order tape now i want to buy the right one!!!
Has someone a link or article number? Dont want to buy just a 3m 2mm tape that is to thik or something...
So 1mm or 2mm?
Is there a difference in hight?

I got this:
http://cgi.ebay.ca/3M-2mm-ADHESIVE-...280211?pt=PDA_Accessories&hash=item255d9bc793

Thank you!
What did you use it for? Only the display and touchscreen or did you glue the display to the housing and the part unter the buttons with this too?
After opening it twice i think i need:
-Display with touchscreen
-Display in housing
-The parts of the touchscreen that stands over the display ( buttons and lightsensor) , to the housing..
Do you know a more exactly name for the Tape?
Someone wort about LSE300 but this is only the category name ;D
But anyways thank you for the seller, the tape was good for yoU?

How did you guys remove/plan to remove the glass from the LCD?
Sent from my HTC HD2 using XDA App

Just warm it and with a razor(razer? you know the sharp flat knives ;D) you cut along the edges.
Just make sure you move the razor parallel between the touchscreen and display, so you dont break or scratch the screen.
For heating up, you can take a hair dryer or put it in the oven for 5-10min. I think 50°C(a bit longer to heat all trough) . More temperature shouldnt be a problem, sun on black surfaces often gets ~80°C but dont risk it, and you need to touch it to remove the screen
------
For the soldering version a little hint:
The cable on the new touchscreen can be soldered from top and downside.
You dont need to solder on top the little overhang, just put a bit soldering tin between, then cable on top and let the heat go trough the cable to heat the tin on the underside=> more space and all the way conected.
There is a little round mark to alighn the new cable. Use this, or the chip on the cable will not fit unter the hole in the housing ;D
If its hard to solder just put a bit soldering tin on the display first. Then put the cable above and press the soldering iron on top. The soldering tin you put between will connect them perfectly. Use a tool to press the cable on the display untill the soldering tin is hard.
The secret of basic soldering skills is not to move after you take away the soldering iron until the tin is hard, every movement in these seconds makes the soldering spot weak or its not connected right.

Wow that's quite interesting. I broke another hd2 a while ago, and its just laying around. Screen works well, I just hated the cracks. I may try this out...
Edit : if someone could make a video tutorial, that would be sweet. The one online isn't so great
Sent from my HTC HD2 using XDA App

I haven't used it yet, because I bought it last week and they're still shipping it to me.
I'm going to be using it to replace the tape between the old digitizer and the LCD.
I thought the display-to-housing tape was padded, wasn't it?

Yes, there are many kinds of different tapes. Thin, padded, metalic and some seemed to be more like glue dots.
But i dont think its so important do rebuild this exactly
Starting from 5:00 he seperates Display and Touchscreen ;D
But the guy soldered from top, you can actually see it at 7:40, i think its better to solder between display and cable, as i tried to describe above..
That lucky guy was able to reuse the whole tape as it was, but im not sure if it is still so good, even if it is one piece.
When my tape comes, i will eventually make a little screen replacement video ;D
But my camera is not very good at close-ups, but i try ;D

[GUIDE] Xperia Arc Disassembly

EDIT
"meyourchum" has provded a link to get offical disassembly instruction with lot more information.
Check it for yourself
Hello folks,
I had a chance to work on my friends arc who bought a Rogers version and dropped it. He had it totally mess on the case and needed the full housing replacement.
I hope that doesn't happen to anyone. I didn't take any photos but I am trying to explain everything as it was to help anyone with this.
General Note:
- Anywhere you got stuck, watch some X10 Disassembly video
- Be very gentle to your phone in this process
- Besides all the screws the rest of the phone is put together with glue(Sticky Back) and snap(plastic for main board)
- Using this information on your own risk as I don't take any responsibility if anything happens to your phone.
Instruction
1) Remove the back battery cover. Thats the easiest part
2) Need star shaped screw driver[Trox](I bought the set for $5) there are 4 screws like that and two which opens with phillips screwdriver(tiny) This is what I bought
All the above we all have seen them
3) After removing the 6 screws remove the front fascia of the phone with a guitar picks, something skinny but sturdy*
* I recommend not using anything other than rubber or plastic in the whole process.
4) Main board is snapped in with plastic to the body which easily can be opened.
5) Little board on the bottom is glued(sticky back @ top) which you can remove with pulling little hard but make sure you don't break it.
6) Majority of the wire you see connected to mainboard can be discounted (snap in wires)
7) Removing the screen: from outside of the phone (like you are looking directly to screen like you normally do) you need to put something under neat and raise up the screen. This part has glue as well and its hard to lift but I did it and it should be possible.
8) if you are doing a full housing replacement, then there are stuff here and there that you need to remove and re-use it on the new housing(Like 3.5 mm jack, HDMI lid, etc.)
Good Luck and let me know if you have any questions.

1st time... ehm.. taking the Arc apart, that is!
Helluw there
Just read your post, and thought I wanted to share with you, that I might be opening one of these slick little things. My friend broke his display, and the ISP is talking about some 'off the scale' repair prizes.
...So, he asked me to do the job
Told him I didn't have any experience on the disassembling of this phonetype, but he trusts me it seems
I might return with some questions in case of problems, is that OK with you Nimche?
Greetingz

Hope u have the courage to make a video next time

I change full housing and not sure if you have to remove the hard key button from the bottom end of the phone too or not but that little board on the bottom is glue which you can remove with pulling little hard but make sure you don't break it.
- All the wire you see connected to mainboard can be discounted (snap in wires)
- There is a big one which goes to the screen you have to dis-attach that before removing the screen
- Removing the screen: from outside of the phone (like you are looking directly to screen like you normally do) you need to put something under neat and raise up the screen. This part has glue as well and its hard to lift but I did it and it should be possible.

Can you answer this??? It get's hot here (and also in the same spot on the front.. so what's inside at this point??

CPU is right behind the second cover. I wish I could take some photos.

Thanks for the clarification. I was also suspecting since this area gets damn hot when playing games and even at charging (sometimes).
So seems like they move the CPU from behind the battery in X10 to near to the camera in Arc .

Can I change only the front faceplate around the screen without removing the mainboard? How easy would that be? I want to change mine to Misty Silver as Rogers only carry the Midnight Blue.
Also, for glued parts, do I have to glue them back on the new housing?

Glue part, they are more sticky than glued. You just simply stick it back where it was.
Where is the silver face you found?
This is retarded from them...
Digitizer and screen(one part) are sticked to the front face. In order to for your to change the faceplate only(front) you may have to go through the whole process because the wires from digitizer are going through a big hole to the main board. You don't want to mess around with $700 or $800.
Inside, everything is small. really small. I thought I totally screwed up the whole thing. Technology has gone forward alot since I was a kid putting radio together.
Good Luck

Yes, there are two board one above battery and one below batter @ bottom of the phone
On top is the main board
on bottom is the board for hard keys.
Nicely put together but they could have done a better job there....

Are there three parts to the housing? I assume there is the front plate, middle housing with the chrome, and the battery cover. The mainboard should be in the middle with the chrome. So I can't just detach the screen front the front plate? What is holding the three pieces of housing together? The six screws?
There are silver housings on eBay from time to time. Though, blue is a lot more common.

Three pieces. Back battery cover which is nothing.
Then there are two main pieces.
Chrome which is more like a holder of the fascia.
If I remember correctly, the front Fascia is the one holding all the board on it including that metal look piece(aluminum probably)
I will take photos and upload here...

Uploaded photos to the first post...

Hey, I'm looking to replace the chrome piece which has a few nasty chips in it, after removing the second back cover, how easy is it to take off that chrome piece?

Great post

How can I replace digitizer? I dropped my phone and the glass cracked

anyone know where i can get the tiny screw driver? I cant seem to find the correct one. they are either too small or too big.

how easy is it to replace the front cover, ive cracked the top of it and chipped a bit out the side (surrounding the screen) i presume it'd be simple enough. And does anyone know where i can get a good quality/genuine front cover replacement?

Sorry, you could have sent a private message.
I bought the screw driver here at local tool shop. Home Depot sells them.
Its called Trox Screw Driver and I bought exactly this one http://www.homedepot.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10051&productId=100087664&langId=-1&catalogId=10053&ci_sku=100087664&ci_kw={keyword}&cm_mmc=shopping-_-googleads-_-pla-_-100087664&ci_gpa=pla&locStoreNum=618
I don't have the packaging but they should be standard.
Good Luck

You can find the whole housing between $30 to $40 but the front cover is that actual main piece that holds all the internal components + the screen.
If the crack doesn't bug you much, I would not do it since you have to replace the sticker behind you battery as well, which is not easy to peel off + you have to take the screen off the old front fascia which is glued and kind of hard to take off.
Downside of the whole thing for me was the sticker. I have to find an alternative for this problem.

Replacing Touch Digitizer fix NonResponsive Screen?

Hey everyone my HTC HD2 got the Non-Responsive screen problem a week ago, & did a lot of research and found out that it was most likely a hardware problem with a cable..... So a lot of people would tell the people with the problem that the "Touch Screen Digitizer" is dead (like the cable), or it needs to be cleaned... pretty well go out and buy a new one... BUT I have never found evidence that someone has done this and it has successfully "cured" their HTC HD2 Non-Responsive touch screen problem...
So I was looking for anyone on the forums that could confirm this is a solution or give me any tips on what I should do.... AND no I don't have enough money to get a new phone, nor do I live in the USA so I can't send it in to fix it...
This is what I was going to buy for it:
http://www.ebay.ca/itm/NEW-OEM-HTC-...781?pt=LH_DefaultDomain_0&hash=item519a3d2e45
Thanks for taking the time to read my Thread, its much appreciated!! I hope I can find a fix!!
PS: If anyone wanted to know what it looks like out of curiosity I posted 3 pictures with RED circle HIGHLIGHTING the problem when I try to touch something....

My digitizer has been a bit dodgy for the past few months. It's ironic that when I finally found out what the issue was and called HTC, my factory warranty had ended exactly 4 days prior to the call.
Fast forward 3 months and my phone has now been unresponsive for 3 hours despite my prying and tweaking various hard parts.
I disassembled the phone down to the main board just to see how hard the install is, but it's a bit intimidating once it's time to start pulling all the film and ribbons. A bit too tight and small parts for my liking.
Time to hit CL to see if I can find a cheap replacement.
Good luck with your repairs. I may be following in your footsteps if I can not find a good deal.

Yeah I will see how well it goes... if anyone has useful info, i will be more than grad to hear it
Thanks

Many people attempt to replace a digitizer, but I simply don't recommend it, we see enough of do-it-yourselvers who created problems in addition to the original ones.
What I do recommend, however, and I stated it on many threads already, is to get an LCD+DIGITIZER assembly. Simply because it is easier to fit. Not saying the overall fitting is easy, always depends on your overall skill, so ensure that you are familiar with the procedure BEFORE you begin. But you will save yourself a lot of trouble by getting the whole thing, as opposed to the digitizer only for the sake of a few bucks.
However, if anyone still feels intimidated by the whole thing, I am on the lookout for working main board. Advertised a few times in the marketplace with limited success. So if anyone smashed their baby and will be looking to replace, rather than repair - drop me a PM. I am in NZ. Will pay by Paypal.

Mm i've replaced my HD2 screen just last night. Trust me it's among the most complex phones around.
Unless you've done a few phones before i wouldn't advice you DIY. Otherwise you can look carefully at the Leo Ds. and Leo As. guides on youtube. those helped me!
Mm i killed my LCD in the process of removing the digitizer as it's stupidly glued on to each other and the LCD glass is thin as hell.
Get the set, it'll save you your time
Mm i got mine of ebay, from the seller goodgoodsecho. It works perfectly well for me!
All the best!

Thanks I will check it out, hopefully it won't be to hard and I hope I can repair it!! oh and could you post a link of the youtube & manual you used to replace your screen?? Thanks
Oh would anyone suggest then just calling HTC and sending it to them to repair?? or does that cost to much??
Thanks everyone for the help

One word of advice I have, is just remove the LCD/digitizer module assembly and don't remove anything else.
I have no idea why these videos and manuals have you pulling circuit boards, flex cables, and disconnecting stuff just to remove the LCD module. All you really have to do after removing the rear housing is to cut through the double-sided tape holding the LCD module to the main frame, being careful to know where the flex is and not to go too deep there. I used a credit card for that, but anything similarly flat and thin should do.

Yep, there is absolutely no reason to take off everything like some people seem to think is necessary.
The way I'm talking about requires removing LCD+digitizer. In fact, I think you'll always have to remove both because the connector for the digitizer is under the LCD. Anyway, the way I did it, I went from removing the the phone insides from the rear housing straight to separating the LCD+digitizer assembly from the frame. No removal of any boards or flex cables. The only cable to be disconnected is the LCD+digitizer assembly one. Getting it disconnected and reconnected does require unplugging the front button flex and removing the screws for the bottom logic board to loosen it, but that's all.

Well, it's not that simple because simply getting the HD2 insides out of the rear housing is difficult if you've never done it before. I believe the screwdriver you need is a Torx T-5. Once you get the screws out, you will need a plastic opening tool to go between the digitizer and rear housing frame. They look like this:
http://www.ifixit.com/Tools/Plastic-Opening-Tools/IF145-000
I found it comes out much easier if I use the tool to make a gap along the top edge and then slide the entire end of a scrap credit card into that gap, then that makes the whole assembly easier to pry out along the sides with the tool. I know on one of the vids, the guy takes forever doing this part and I can understand why, but once I figured out sliding a credit card into the top gap as far as it would go, I was able to get it apart much easier.
I can't answer whether the phone will work properly, because I just ordered the new digitizer over the weekend and haven't put it back together. I did remove the LCD+digitizer assembly and then re-connected it and put it back, then powered on the phone just to make sure pulling the LCD didn't hurt it - it didn't, everything worked as well as it did before. I did manage to crack the digitizer more when I tried to get the insides out of the rear housing before I figured out the credit card trick, so fortunately I was not trying to save my digitizer as it was already cracked. If you are just wanting to try to clean or fiddle with the connection, then you're going to have to be a LOT more careful than I was because it was all too easy to crack the digitizer!
I'm guessing yours probably needs replacement though. I sent my HTC Surround in for a funny acting digitizer, and the digitizer was replaced.
Oh, and if I would have bought an LCD+digitizer pre-assembled unit, that would have been super easy to replace. However, I opted to save $50+ by buying just the digitizer. Not too sure how I'm going to prevent dust getting in it, and I've read thickness of the adhesive is critical. I may regret it later!

I can't answer whether the phone will work properly, because I just ordered the new digitizer over the weekend and haven't put it back together. I did remove the LCD+digitizer assembly and then re-connected it and put it back, then powered on the phone just to make sure pulling the LCD didn't hurt it - it didn't, everything worked as well as it did before. I did manage to crack the digitizer more when I tried to get the insides out of the rear housing before I figured out the credit card trick, so fortunately I was not trying to save my digitizer as it was already cracked. If you are just wanting to try to clean or fiddle with the connection, then you're going to have to be a LOT more careful than I was because it was all too easy to crack the digitizer!
I'm guessing yours probably needs replacement though. I sent my HTC Surround in for a funny acting digitizer, and the digitizer was replaced.
Oh, and if I would have bought an LCD+digitizer pre-assembled unit, that would have been super easy to replace. However, I opted to save $50+ by buying just the digitizer. Not too sure how I'm going to prevent dust getting in it, and I've read thickness of the adhesive is critical. I may regret it later!

Ok thanks I think thats what I am going to do, first dissemble it then try to move the cable around because, just yesterday it started to work again and then today it isn't working. I will contact you if I have a problem or get stuck, if that is ok with you
Thanks a lot

Yeah, no prob. I can post a pic of the digitizer lifted from the frame which shows where the adhesive tapes are that you have to go through, if it would help.

One word of advice I have, is just remove the LCD/digitizer module assembly and don't remove anything else.
I have no idea why these videos and manuals have you pulling circuit boards, flex cables, and disconnecting stuff just to remove the LCD module. All you really have to do after removing the rear housing is to cut through the double-sided tape holding the LCD module to the main frame, being careful to know where the flex is and not to go too deep there. I used a credit card for that, but anything similarly flat and thin should do.

Hey lolz I need your help already, I just took off the back housing and now Im lost on what to do... It looks to me as if you do have to remove the cables from the motherboard to get to it?? and what is the double sided tape? and isn't everything connected to the lcd?? lolz this is my first time doing any phone disassemble.. Thanks
added a picture of what I was thinking of doing... or am I doing this all wrong... because you did say we don't need to remove any flex cable or wires and stuff
Thanks!!

Nope, I didn't disconnect anything except the circled connector on the far right of your picture. You will need to do that to remove the LCD flex cable from the logic board.
I've attached a pic of the LCD module loosened from the frame. What you do is use something thin and flat to separate the adhesive tape holding the LCD to the frame. You will need to lift some of that black fabric tape on the edge to see where the LCD module meets the frame. Near the top, you will probably have to slide your separating tool all the way through to separate the tape (I used a scrap credit card). Avoid the area where the LCD flex cable is, because you could damage it! It's on the lower right of the LCD if you are looking from the front. When the LCD is loose, lift up from left to right (when LCD is facing you), pretending that there is a hinge on the right side. This is because you don't want to put any force on the LCD flex.
Once you've got your phone looking like my picture, you can remove the "captain" (orange tape), unlatch the LCD flex from the top, remove the button flex from its connector, then loosen the bottom logic board from the frame just enough to pull the flex out of the connector.
I hope that makes sense! It probably helps to know that a very strong double-sided sticky tape is all that holds the LCD+digitizer assembly to the frame, and there is only one flex cable connecting LCD+digitizer assembly to the rest of the phone.

Awesome I will try it now, I do need to heat the screen some for the tape to get sticky so I can pry it off right?? and I am guessing once you have removed that tape you can't "just stick it back on together and it will work right?? right??

You could try heating; I didn't, but maybe it will come apart easier if you do. In the HTC factory service video, they mentioned putting the whole phone into the oven to loosen the tape. I didn't know if it would be a good idea to do that complete with all the circuit boards or not.
No, without heat, the tape is definitely ruined and I will need to replace it. I was planning to use some leftover tape I have from fixing iPhone digitizers so I didn't even attempt to salvage the existing tape. Not sure if it's even possible to salvage that tape considering you need to stick some kind of tool in there to separate it.

Alright thanks I have to go and don't know when I'll be back, but I will try it tonight and hopefully I don't break anything...
Thanks for the help!

[Q] is that possible?a guy replaces full display (lcd+digitizer) in just 3.5 minutes!

just found a very easy way to replace the whole display in just 3 minutes by accessing it from the front side..
i am not yet allowed to post the link, but if you google this
IMPEXTROM CAMBIAR TROCAR DISPLAY HTC HD2
you will see the 3 minutes video
seems possible as there are 19 positive and just one negative vote on this video..
(my display was broken, but have worked for a year or so.
now it is frozen/ unresponsive and i have purchased a full display.)
but it seems too easy to be true ...
any hints?
thanx &cheers

That been set up for the video as you can see it been off before & the chassis the lcd is bonded to is clean of all bonding tape :-/
Also original has signal interference tape runing down sides across all 3 layers.
also if you heat the front first thing to seperate is the digi from LCD as the lcd to mid chassis is a strong bond.
Best way is popping them out of rear cover, fitting a pre built lcd/digitizer is not hard, just use quality adhesive to hold lcd to centre chassis & buy pre cut black foam tape for the top & bottom digi glass edges or rebuild is next to pointless without this done well.
I've done a good 30 odd HD2 screen & mainboards & no way I could do it to my standard via that video.

Hi Mister B - thanks a lot for your advice, i believe you are right!
but as i have never attempted to disassemble a mobile phone, is there a video tutorial how to do that properly for an absolute beginner?
as I need my phone functioning tomorrow, i'm considering to try it in the morning.

Not sure if Mister B will reply in time, there is a good thread here http://forum.xda-developers.com/showthread.php?t=1566179 with a video in post 2 else google hd2 disassembly youtube perhaps

Hi Robbie P,
Thanks a lot for the link!
Now it seems I will have to postpone this operation for a day or so, until i learn:
1) What time I would need (seems about 2h for a beginner)
2) What money I would need - as I have to buy these tools- what would be a price... i guess 10-15 euros?
(BTW Finally I guess that people who published aforementioned 3.5-minutes tutorial did so not to help us, but to make us damage our smartphones, so their services would then earn more, repairing it?
As I see no other explanation...Now found another such a scam video -
just google " HTC HD2 repair, disassembly manual ")
Cheers

Have a good read of link put up by robbie p
I done a few posts in it that worth looking at as you don't need remove the flexboard & volume button & antenna cables which saves a lot of possible accidents & hassle.
Most important thing is extreme care, volume button is damaged easily if pry of back badly or with screwdriver. antenna tabs are snapped off mainboard with poor handling while separating the layers.
It easy to do but first one is never perfect unless you really pay attention.
You don't need much tools, a basic kit from ebay for about 4euros will cover you along with things you probably got already such as hairdryer & razorblades etc.
Just buy good padded tapes to fit top & bottom of digitizer & strong tape to bond lcd to centre chassis

Hi Mister B!
Thanks a lot for you precious advise.
Will try to do it myself, not in a hurry, as soon as I get 3 hours spare time - hoping it would be enough.
Then I will need to install some good Android instead of the original WM6.5- but that is for another topic
My Qs:
You don't need much tools, a basic kit from ebay for about 4euros will cover you
this is what I got with my display from Ebay: Is it enough?
1 pry tool ,1T5 screwdriver and 1 T6 screwdriver.
Just buy good padded tapes to fit top & bottom of digitizer
I also got this one from Ebay: is it good? if you paste the title below into ebay.co.uk it you will see more details:
2mm Double Sided Layer Adhesive Sticky Tape Sticker for Mobile Phone Glue LCD
& strong tape to bond lcd to centre chassis
Which width, and should it also be double-sided?
Cheers

For tape you want this >
http://www.ebay.co.uk/itm/LCDFIX-Fr...765?pt=LH_DefaultDomain_3&hash=item1e9ebb1595
I assume you have lcd & digitizer pre-built new !?
You would be better off with couple more decent pry tools, the green ones tend be better than the blue plastic stuff.
I use 2 pry tools on top of HD2 either side of speaker grill as makes back housing removal a few second job & leaves not one mark if done right.
Only other thing you may need is tweezers & cleaning buds for old glue.
top digitizer tape need be right or blocks sensor hole or looks shabby.
Don't force the old lcd off centre chassis as if gets bent then never fit back right, warming it up with hairdryer helps ease it off.
I always have a spare button board on hand too as makes it easy bench test the lcd/digitizer hook to mainboard side by side with battery held on mainboard pins & spare button board used to power on, also good as likely find old board breaks if gone brittle.

tools I've got
Hi Mister B!
Thanks so much for your suggestions!
Yes, I've got the full display, and only the tools as on the photo.
My few Qs:
Only other thing you may need is tweezers & cleaning buds for old glue.
Could not find plastic tweezers, only metal ones... But those cotton sticks for ears i have
I could order the LCD tape, though it seems a long wait (7-10 days) for express delivery up here, so is there an alternative?
Thanks for a link to the button board! As I guess mine is damaged, for during last few months I had to press hard on the power button to get the phone responsive again. Then even this trick stopped working.
But also due to the longer waiting to get in from China - is there a way to test and learn if i need to replace it , before starting digging into my HD2?
Cheers

I would get the lcd digi top/bottom tape kit as what you got in big roll will be no good.
all else is good.
button board is handy as ribbons go brittle so can break plus you can use it to power up the device in a pre build test with lcd/digi & mainboard laid flat side by side & new ribbon plugged in to mainboard to power on. Most stuff makes it to uk pretty quickly, quicker order - quicker get it

Well, i will then order both items today, in hope it won't take too long to deliver up here (Belgrade, Serbia).
A video tutorial with all the tricks you have suggested would be the easiest way to follow, but it seems there's no such a video - yet.
Certainly, I'am either not sure whether will be able to film my own attempt.
Mister B - thanks so much! Following your suggestions, and the topic mentioned by Robbie P - I will likely manage to do the job properly!
Cheers

If have any question during rebuild post them here & I will respond as soon as see it.
Good luck ...

Thanks!
