Just bought a HD2 from craigslist for $50. It works except the digitizer was cracked.

Diassembled the phone last night and removed the digitizer from lcd. Used a blow dryer to soften adhesive and fine screwdriver to separate. On my may back to my work desk I dropped the LCD, I then partially assembled just enough to power up and Thank GOD the LCD is fine and not busted.

I ordered, new digitizer, iphone adhesive (China is too far for a roll) yesterday and hopefully it gets to me today or tomorrow.

In the meantimem I have scraped off all the old adhesive with a small blade and cleaned the stickiness with acetone.

Thanks for this thread for leading me in the right direction!

HD2 for about a $100, pretty good bargain.:D
[HD2 General] FloatHeavy:
Glad to hear feedback! The hardest parts of the fix for me were the volume rocker (still doesn't quite register) and tucking the wires snug so the housing doesn't bulge...How did those aspects of the fix go for you?
[HD2 General] prag16:
I'm stuck way back at the beginning

I removed the four screws, but I can't even get the dang screen separated from the frame, as they do at the beginning of the video. They make it look SO easy in the HTC video. I feel like I'm applying an obscene amount of force from the back while prying near the top, and it barely will budge. Any suggestions?
[HD2 General] OfficeLinebacker:
heat it up?
[HD2 General] prag16:
Well, I thought the heat was for the digitizer/LED panel.

It's clear that I'm gonna **** this up, heh.

Granted, I'm not yet using the real tools I'm supposed to be using... pry tool and crap on its way from Hong Kong :(
[HD2 General] frostmore:
you might as well upgrade the ram and see if your 1 gb can be upgraded to 1.5 or 2gb.....
[HD2 General] keithsipa:
Dont heat it up! You will damage the plastic housing when you are prying on it. Yes, it can be very tough to seperate. I used an iphone suction cup to pull on the digitizer while prying on the top left corner (to get started) with a semi rigid plastic knife between the housing and lcd assembly. Keep at it and you will start to see it moving, it comes very slowly from my experience.
[HD2 General] prag16:
I'm surprised nobody ever made a full guide step by step on how to do this, seeing as MANY people have had to do this. The lack of any real guide I think has caused many more questions to be asked over and over.

Also, the video in the other thread is VERY unhelpful. Piecing together various chatter in this thread was way more helpful.

Once my stuff arrives later in the week, I'll give this a shot; wish me luck...

Just a couple more questions...

@travis.garrison: You mentioned reglueing the frame, but you did NOT mention reglueing the LCD panel to the glass/digitizer. Did you reglue this? If so what did you use/how did you do it? If not, how are you keeping the pieces together?

Also, I don't see how reglueing the frame is so important. Everything seems really tight and snug.. do we expect the screen panel to just fall out one day if it was not glued??:confused:
[HD2 General] prag16:
Alright, this keeps getting worse.

I finally got it out of the case/bezel, but I seem to have caused a crack in the LCD panel in doing so (I'm assuming this is what happened since there is a crack that now resides UNDERNEATH the outer glass. But I turned it on and all screen pixels still work.

After causing this crack in what I assume is the LCD panel I put it back together to make sure everything still worked before moving on, and now the touchscreen is 100% nonresponsive! I don't know what I could have screwed up; nothing seemed to break when I completely removed the case/bezel. What the heck did I do??
[HD2 General] OfficeLinebacker:
If the display works then the crack is not in the display. There are two levels of glass. It goes Outer-touch sensor-inner. You cracked the inner glass and damaged the touch sensor, most likely.

Proceed as originally planned, with extra caution, then report back.

[HD2 General] 0swald:
Hi all. Just detached LCD from touch screen using thin nylon string. It took me 10 min, LCD looks brand new. Could take me less time if had not read this frightening thread about cracking display while detaching :) Took several good shots of JD to celebrate.

Tomorrow's problem is soldering after sobering :)

Good luck everyone.
[HD2 General] OfficeLinebacker:
Interesting. Did you heat it up?
[HD2 General] 0swald:
No, but the temperature might be slightly above normal cause I've heated it a bit before - while detaching LCD from chassis.

I started from upper right corner, slowly moving to upper left and then down. The only problem is that you need to hold the unit and pull the string the same time. A good idea could be to ask someone else to hold the unit.
[HD2 General] lebmb:
i've done like 5 so far, i pretty much been using a guitar pic to slice through everything, the last one i just did this weekend i didnt even heat it up

i am curious as to how is everyone gluing back, i always have a problem after a while with the glue separating, specially from the buttons and the screen lifts up and the buttons become flat, its very annoying

i use the tape from ebay the 3M 2mm one which is great for the whole thing, but not the bottom part.

also on another note, by not heating, i was able to save most of the original tape, i put some rubber cement on both sides and glued it back on nice and tight, nothing moves even after a while, only problem again is the bottom
[HD2 General] profahmad:
I had the issue of the buttons flattening or being angulated after assembling the device and it drove me crazy. The screen wasn't completely flush with the outer chassis either. I reopened my HD2 last night as my flash cable somehow loosened itself and I decided to use some very cheap Pritt stick to glue to LCD and digitiser to its chassis (collectively the LCM). I applied liberal amounts to the markings of where the previous adhesive had been applied (if you look at the second image you can see the black marks, including a thin strip below the AP buttons). It worked! What also seemed to help is squeezing together the LCM and outer chassis before tightening the four black T5 screws.

The first time I opened it was to replace the LCD which was exhibiting significant LCD bleed. Separating the LCD & digitiser from the plastic wasn't too difficult, I heated it a little by holding it in front of heater and separated with a guitar pick. I was careful not to pry open and separate the two pieces though, I can see how easily that could have damaged the LCD if rushed.

With the brand new screen and a new battery cover I found for a few pounds on eBay as my old one was peeling, my HD2 feels as new.

I've attached some pictures I took, just for the sake of showing the insides of my HD2. :)
[HD2 General] a_ok2me:
Grey / Black Foam Tape

What kind of tape is this - the grey / black foam tape around the edge? Am I correct in understanding that people are suggesting to use the 3M 2mm tape as the replacement?
[HD2 General] profahmad:
That's the suggestion but I didn't see the post before attempting my assembly. The black/grey in my images is the old tape originally keeping the screen together that remained after I first opened the device. I applied the 'glue' directly onto those surfaces.

Sent from my HD2
[HD2 General] OfficeLinebacker:
You are correct, sir.
[HD2 General] lvrijn:
Always when you reassemble the LCM with the frame REMOVE all of the old adhesive!

You cant glue on glue.

But it's not hard to get the old adhesive off.

When the LCM with frame has been in the oven for like 5 minutes on 60 degrees, it's easy to pull of the old adhesive.

I use as adhesive the 3M adhesive kits for iPhone 3.

There is enough adhesive on those kits you don't use for iPhone.

For the bottom part, i also use the 3M adhesive.

When you reassemble the LCM in the frame, you have to press hard down and then press it in the frame. This has to be done, or else the hardware keys won't work, or don't give feedback.

Never have problem with this method.
[HD2 General] profahmad:
Also the alignment of the LCM in the frame is important, it has to be near perfect as a few mm discrepancy will result in no feedback from the hardware buttons. There's a very small margin of space to play with. I noticed this the first time I assembled the device after opening it - sliding the screen down a mm or so (it was loose at the time) would rectify the issue.

[HD2 General] HotRod11686:
my digitizer gave me hell so i bought a new one and took the phone apart. it was a PITA removing that damn glue. needless to say too much force was used and I accidentaly dismantled the LCD housing and this caused me to get a few dead pixels >_< FML !

I never even bother getting down to the digitizer , actually I noticed the digitizer ribbon cable was unplugged the whole time > FML x2

I didnt get to glue the phone but did reassmble to test . viola touch works but i had a cluster of dead pixels X_X

question!

i read bout 3 diff mm of 3m, someone said 3mm, another 2mm, and lastly 1mm. which is the correct one for the job? I need to glue the LCD/Digitizer module to the Body
[HD2 General] perseus68:
Well I have the same question here :rolleyes:

What's the best adhesive/glue to stich the LCD/Digitizer moduel to the Chassis?

I saw that someone used Pritt Stick glue here but I checked it out and that's recommended for wood and paper, not plastic.:eek:

I'm stuck at this point..
[HD2 General] bib*oops:
Best is double sided adhesive tape 4-5 mm wide, no matter which brand!
[HD2 General] perseus68:
Thanks mate ;)

I'll go ahead with it.
[HD2 General] Mister B:
I use wide but thin double sided tape applied to both sides to match on mating but also a spot of PU40 (polyurethane adhesive) in corners & centre near edges & near narrow bonding point as 3M alone tends to lift regardless of quality ect & getting the LCD to chassis as flush as possible makes a big difference in button function & touch screen being flush with back cover edge lip.

PU40 can be sliced with thin blade if future strip-down is required.
[HD2 General] bib*oops:
Well, I didn't see your thanks!:rolleyes:

Maybe using THANKS button could help?!
[HD2 General] y2kai:
I think its just me, but I cant seem to put the volume button back into the proper place. I manage to get it in a few time, but it was not hitting the sensor..... anyone got a tip on getting fitted properly?
[HD2 General] perseus68:
LCM replaced but..

..now I have some difficulties with the Volume button.

Most important, the touch screen now does not work :confused:

The LCD+digitizer was bought brand new on ebay and I carefully followed all the instructions of the disassemble/assemble videos.

It was not so hard but now I'd need a test to check if the new Touch screen is defective :(
[HD2 General] bib*oops:
You should consider as possible to have broken some contacts between motherboard and lcd connector while disassembling operation...

But first of all you need to test new digitizer!
[HD2 General] perseus68:
Hi Bib*oops

Thanks for the reply

Well, I think I can discard this option.

I did it very slowly and carefully, by looking at the video on youtube, taking picture myself just in case for each step and never applying much force on the device.

In total, 3 hours of work.

Any idea about how to test the new digitizer ?

I'm really lost at this point...:mad:
[HD2 General] 00Nuclear00:
is it possible to attach a display from an other phone?
[HD2 General] bib*oops:
Good idea, but you could do it vice-versa too: attach your display to another motherboard.;)
[HD2 General] perseus68:
I have the old cracked display still.

It worked fine (touch screen included) except that it was cracked...

Hopefully you are not asking me to un-glue the old touch screen and place it onto the new LCD.....

I'm afraid I didn't get it :o
[HD2 General] bib*oops:
No, you should use your old one(combo, I mean), if touchscreen still works, just to test your motherboard...
[HD2 General] perseus68:
Sounds good. I'll report later today ;)

I'm wondering if there is any way of testing it w/o reassembling everything.

It would save a lot of time.

Thanks meter +1 :D
[HD2 General] 00Nuclear00:
Sry, I meant a different (htc) phone.

The hd2 should work with all hd2 screen replacements or?
[HD2 General] perseus68:
Well, I just re-mounted the old one.

Touch screen works fine damn it!

I guess the new item bought on ebay is defective :mad::mad:

Now I'm almost 100% sure.

:(

Hi guys

Latest update.

I re-installed the NEW LCD+Touch and the problem persist.

Touch screen does not work!!

I checked the codes of the IC and they are identical to the original LCD.

So the new item look identical to the original but it's defective for some reason.

I'm gonna write to the ebay seller asking for a replacement.

Let's see what happens.

Thanks to all

Marco
[HD2 General] bib*oops:
Sure it'll work...
[HD2 General] perseus68:
Hi all

The ebay seller just agreed to send me a new Digitizer ;-)

It is getting even harder now to detach it from the new LCD w/o breaking anything but I'm confident that's the solution.

Regards

Marco
[HD2 General] bib*oops:
Good luck with that!
[HD2 General] Crippius:
This thread deserve a sticky :)
[HD2 General] slashdilon:
I don´t have any experiences with this things.

What you think: Its best buy digitizer + LCD or I can make this replacement???
[HD2 General] cmour:
it's safer to buy LCD+Digitizer,

if, as you say, you don't have any experience..

as this parts come preassembled..
[HD2 General] aftashokz:
I had same problem I brought LCD and digitizer together my hd2 is now in phone shop being repaired by complete I paid 46 pound off amazon
[HD2 General] R-P:
SUCCESS

Haven't checked bluetooth or GPS yet, but at least some stuff works.

Partially due to this thread (THANKS!!!) and of course the leaked official vids.

After 2 years of keeping my company phone in immaculate condition, I dropped it last week less than 30cm/1ft. Cracks all over the screen. Still worked though, but the shards of glass were razorsharp.

I'll spare you the lengthy story, but I got another HD2 with 'water damage' (according to the repair-form). It looked brandspanking new, even had the lens-protection-sticker still over the cameralens. It was in the safe at work, as is yet another with only one crack, as opposed to the 1000 cracks on my phone...

Turns out only the buttons were faulty in the 'waterdamage' one, so I swapped the LCD+digitizer (LCM?) from the 'waterdamage' one to the rest of my original phone and that was it. (In reality it took me several hours, some cursing, damaging stuff irreparably, giving up twice, etc.)

Problems encountered:

(1) When dissassembling the LCM from the chassis, I cut the flexible circuitboard's two separate tracks (possibly the backlight of the LCD???).:mad:

Good advice: DON'T separate them with a knife.

Another bit of good advice: DO separate them with a knife, as using plastic like in the vid WILL NOT WORK and the leveraging will probably do even more damage.

Luckily this happened on the broken screen-phone. The other one didn't even have these two tracks, as it is one with a connector instead of a soldered LCD-processor-flex-board.

(2) The spring-connector of the bluetooth board broke off, had to steal it from the other board.

(3) Coax-cable of GPS module is very easily damaged.

Doublesided tape: I used two layers of photo-tape. The only thing I could find in my town. Glueing the plastic around the speaker and the buttons didn't work with this tape, I used superglue, but this is going to cause me greef in the future...

Conclusion: I am not going to make this my dayjob and I am eternally grateful I didn't have to separate the glass from the LCD (although I planned doing it with dental floss, good idea?). That was my original plan, but I think that is beyond my capabilities.

Double Sided Foam

Like others in this thread I have struggled to find a good substitute for the double sided foam tape that holds the digitizer+LCD assembly to the phone chassis. Thanks to this thread I was able to determine that the foam we need should be 1/32 of an inch thick. I've been searching for this tape for many days and have traveled to many craft stores without any success. The closest thing I initially found online was a large roll that costs around $20. I figure I only need a few inches so most of it would go to waste.

Then today as I was searching again online I discovered that there is a different unit of measure called a "mil" (thousandth of an inch) that is often used in the specification of thickness of tapes. 1/32 of an inch is 31mil. Once I started using this measurement in my searching I was able to find many more web sites that sell something that looks exactly like what I am looking for. I found one site called Zoro Tools which sells many different sizes of double sided foam tape including several that measure 31mil. I was able to pick up a 5yd roll for less than $4 including shipping. I just ordered it so I'll have to post again once I try it out. I just thought I would mention it as soon as I found out about it in the hopes of preventing people from making a complete mess of their phones using glue.

Of course this does not address the the adhesive needed for the bottom of the phone. On my phone it appears that the top had similar foam tape while the bottom had the same adhesive used to mount the digitizer to the LCD panel. I think I will try a little glue in that area since I don't want to spend another $5 for such a small surface area.

I'll report back in a few days once I get the tape in the mail.
[HD2 General] Mister B:
I use black foam double sided tape for top area around speaker etc & bottom button edge area, rest I do with double sided m3 thin tape applied to both surfaces as can rub it on well that way & when 2 taps meet the DO stick.

Also back this up with small dots of polyurethane adhesive in corners, centre points & low tape bond areas.

Result is flush mounted digi that not spongy in use & does not suffer from lifting in long use & hot/cold/damp climates.

dismantling is also easy as polyurethane is easily unbonded (smartly applicated helps too) with a razor blade & care.

Most tapes alone are poor & last device shipped to me with replaced digi fell out after airmail trip ...
[HD2 General] dronchi:
I just got done with the repair using this tape. Unfortunately this tape is "STILL" too thick. I'm not sure what to do now, but I don't look forward to having to pry the phone open again. And even if I did that, I have no idea which Foam tape to buy. I guess I'll keep looking. At least the screen works again. :)
[HD2 General] perseus68:
Hi guys

here again after a looong time.

The LCD+Touch I received from the ebay seller was partially defective.

The LCD was Ok but the touch was not working at all.

Double checked by re-installing the old LCD+broken Touch.

So after ~2 months I'm still w/o my phone !!

After a long series of email with the seller I never received the replacement nor a tracking number of the new shipment.

FYI the ebay seller is e-wholesaler2012.

You are warned ;)

Now that I have sold my Nexus One. i was very sad immediantly just because the phone was sexy as hell and amazing speed. The college i got accepted to sends all incoming freshmen a iphone 3gs and are required to use it to keep in contact with professors.

Now that thats said i want to continue with whats the truth about the nexus.

1) i had a problem with the headphones along with alot of other people when listening to music threw your headphones that came with the nexus you would get a shock... for me it mostly happend when i was plugged into a computer

2) DUST...omg the dust i got under the corner of the screen was annoying the crap out of me. i couldnt get it sent back because i wanted to keep the engraving on the phone. and i didnt want to wait 2 weeks for them to send me my phone back.

3) the phones speed is AMAZING but i feel as if google hasnt completly utilized the speed and GPU yet. *if they can pull this off, things would be so much better than the iphone*

want to add other things about this phone *without being biased* ? go ahead :D lets see if we can get some good information in here for new android users
[Nexus One General] JJackson9995:
:rolleyes:

Yeah... :confused:

Non-biased my ass. The only thing the iPhone does better than the N1 is the app store. To say they need to work on their GPU is just a pathetic representation of a review...

I'm not even going to try wasting my time to make this a worthwhile thread. OP, you're just... Ugh..

Too LAZY to send it back and wait a couple weeks for a problem... That's YOUR fault. There's policies in place to remedy issues... *****ing isn't the appropriate remedy.

P.S. Shocking from earbuds happens with more than just the stock headphones. Go google it.
[Nexus One General] crazy talk:
they need to fix the dust under the screen issue.

!maybe a way to upscale low res images from the interwebs so they don't look like ass on the high res display!

but honestly, i have been more then happy with my Nexus after selling my 3GS.
[Nexus One General] NexusDro:
THe headphones that come with the N1 doesn't work well on other standard 3.5mm jacks because the pins are specifically designed for the N1. Apparently if you insert the headphones into your computer half way it should work like normal headphones.

There was exactly no reason for the OP as he just stated a few well-known issues that people can experience with this phone. Every device has a its own set of issues and the OP will now be fortunate enough to experience the many IPhone problems.

Abilene Christian University.

wow didnt know there was so many haters in here lol go get a life. i posted this thread for new people to look at some issues and as to the iphone headbuds that sucks i have never even heard of that problem i havent been shocked by them for a couple of weeks so we will see if i get that problem.

i spelt threw wrong....woah! your big and bad. big deal go get a life bro. im not wrighting a english paper here dumbass its a forum thread.
[Nexus One General] typ_ex:
that's cool that abilene christian gives out 3gs's. i guess thats how my friend got his. congrats

anyways

the dust issue didnt happen to all nexus's. heck i haven't gotten one speck under mine yet.

also hope you didnt use the stock headphones. i usually assume stock is bad.

enjoy the iphone. i personally cant wait to see what comes out of the next one.
[Nexus One General] pr0cl1v1ty:
thanks bro!

knock on wood lol unless you got a nexus within the past couple of weeks. i pre-ordered mine so i got the first *model* as some have said.

i did use the stock headphones they actually were pretty decent almost up there with the apples iphone stock headphones.

i know all the incomming freshmen for next year get the iPad's for free... im pissed lol
