Success

Hey everyone

first i wana say thanks to waza123 for making this thread and video, i couldn't have done it without your help (without you even knowing lol)

i took a chance by buying a Tmobile HD2 with a cracked screen (really bad) for a really cheap price I think. then spent another $55.85 on ebay to get a screen glass with digitizer and i have to say i was very spectacle cuz i've replaced lcd screens and digitizers on my old MDA, Tilt, Touch Pro and Touch Pro 2 and my friends iPhone 2g (which i demolished) and i can easily say i've ran into problems with all of them but thank god this one went smooth

i saw a video on youtube that looks to have been leaked from HTC on how to disassemble and the nice lady in the video said to bake the phone in the oven at 60 degrees C (140 F) for 5 mins so i figured that would be a safer bet then using a blow dryer not mention alot quieter at 2am in the morning lol

so all went smooth thank god. only minor issue is that i couldn't save the adhesive tape from the old glass so im gona buy the 3m roll on ebay for like 5 bucks and take apart again and glue it right

here are some shots :)
[HD2 General] Sui Generis:
Nice posting! Thank you.

I always wondered: when you take off the battery case, and you look at the phone facing the battery, you will notice that on both sides of the phone, by the bottom side of the battery, there are 2 metal round metal bolts that would touch the battery cover when it closes.

From the youtube clips listed, I couldn't figure out what is the purpose of those bolts and how important are they? Does anyone know?
[HD2 General] Swiperaja:
What doble sided tape can I use for assembling?:) Can u give me some link from ebay?

Thanx in advance!

I am tried with one but not holding well enough: (

I have a UK HD2 with a cracked digitizer. Would this be the T8585 then? I think I will purchase a digitizer+LCD combo as this will be much easier to install. How do I know whether I need to purchase a solder or solderless digitizer+LCD?
[HD2 General] Tenpin:
Hi guys I have two HD2's now, one which has a touch screen which doesn't work. So it needs a digitzier replacement, if anyone is interested in buying that HD2 please pm me.

(Edit: Sold now, thanks for the interest. Bought a working one now)

Regards,
[HD2 General] jackpku:
Very thanks.But the file cannot download now...:(
[HD2 General] GnatGoSplat:
UK HD2s usually use soldered digitizers, but if you're replacing the combo, then it really doesn't matter. The soldered or solderless connection is between digitizer and LCD module. With the combo, it's already pre-assembled so you don't need to care about that connection. The combo-to-PCB connection is the same on both.
[HD2 General] EViS:
What exactly needs dismantling to swap out a combo (digitizer+LCD)? I'm a bit put off by hearing a fair few of you saying that after putting everything back together, certain aspects of your phones stop working. Do I risk damaging other parts of the phone when installing a combo? Or is it a straight swap and nothing else needs disconnecting other than the LCD?
[HD2 General] bib*oops:
PM

Check your PM!
[HD2 General] GnatGoSplat:
Some people dismantle the whole thing, removing every single board and disconnecting every cable. All I did was removed the LCD+digitizer assembly, and loosened the bottom circuit board by removing the 3 screws and button flex in order to reach the LCD+digitizer connector. I'm not really sure why some people take every little bit of it apart. I don't really think it would be easier that way, although I did hear that someone found doing it my way to be very tricky to work the LCD+digitizer flex back into the connector on the lower board, but I didn't have any trouble with it at all and I have done it multiple times. Another guy who was sending me PMs tried to do it my way, but he cracked the new digitizer when squeezing the phone back together. I guess he squeezed too hard, I had no trouble at all with that.
[HD2 General] EViS:
What screwdrivers do I need to replace the digitizer+LCD combo on a UK HD2? Is it a T5 or T4 (or both)?
[HD2 General] EViS:
Could anyone answer this please?
[HD2 General] EViS:
I replaced my LCD+Digitizer combo following your instructions and although it did take a painstaking 4 hours, the new screen is in :). Obviously some copper tape had to be peeled off and couldn't be put back, any idea what the risks is of now not having this in place? Potential shorts?
[HD2 General] GnatGoSplat:
Are you talking about the clear orange tape that goes on the connectors, or that fabric-covered copper metal tape that goes on the sides?

Either way, I don't think it's all that important. The orange tape on the connectors probably just prevents the little plastic latches from popping up and letting the flex cable fall out if the phone experiences shock (like dropping), but I don't think that's likely to happen anyway. Many phones have such connectors and no extra tape added. The copper fabric covered tape on the sides is probably just to partly block out excess LCD backlight from being visible in the gaps between housing and touchscreen, as well as maybe improving stray RF emissions.
[HD2 General] EViS:
I forgot to put the plastic orange tape back onto the connectors too! I was referring to the copper tape along the sides of the phone, it was connected to a large piece of copper tape which is stuck onto the mainboard. Could it be some form of grounding?
[HD2 General] GnatGoSplat:
Yeah, it's probably for grounding or reducing RF emissions. I think that piece of tape had been cut or torn on mine because someone had been into mine before and then gave up. I don't think it'll make hardly any difference at all.
[HD2 General] Scotto:
Using your experience as a start, I managed to replace the digitizer with less steps (US T-Mobile version, with plug-in connector)

Steps 1-3, the same.

Step 4: With LCD still attached to board by flex cable, heated the lcd/digitizer with a blowdrier. Carefully slid a quitar pick around the edges to loosen the glass from the LCD, while being very careful not to stress the LCD flex cable. Removed the glass. I accidentally cut through the digitzer flex cable when doing this, but no big deal because the old digitizer was broken.

Step 5: Carefully cleaned LCD with soft eyeglass cloth. Used double sided tape to mount new glass. Used tweezers to route digitizer flex cable and plug it in.

Step 6: Reassemble.

This method is a bit challenging because it would be easy to damage the LCD flex cable. However, reassembly is much faster.

If anyone else tries it this way, I would like to hear about your experience.

HD2 wont turn ON (Back panel off-works,assembled together-doesn't)

Put in new LCD and digitizer. Once replaced, before assembling phone back i attached battery and ran test. Phone turns on and works fine (i even tried to put sim card in and made calls,also checked wi-fi etc ). BUT when i assemble phone back putting back panel in place(not battery cover) i cannot turn it on.I tried it 3 times. Back panel off-works,assembled together-doesn't. I obviously squeeze some contact somewhere or who-knows what can i do to fix this problem...

Any Idea????
[HD2 General] jngggggggg:
hey all this is an awesome thread and i have looked through most of the pages (1-12) and am getting confused by the wealth of information provided by everyone. Just to clarify:

the p/n on the back of my hd2 is 99hjy034-00. is this the regular version?

after consideration, I've decided to buy the digitalizer and lcd screen all in one because i do not have soldering equipment and would rather pay more and not have to worry so much about breaking anything. Is there a guide out there on what needs to be done when you buy this combo and not just the digitalizer?

similarly, to my previous question, what materials will i need if i buy the combo back instead? I'm planning on buying this one. anything else i will need? tape etc.

Been a long time since I posted here.

A few months ago, my 10 year old son dropped his HD2 (my old HD2 with CM7 Nightly loaded) and the digitizer cracked. That phone had been dropped so many times, but the day he dropped, it must have hit the corner just wrong. Shame too because he loved to use it as a mp3 player, youtube player, netflix player, and much more.

At the time, I got disparaged by all the videos about how involved it was to replace the digitizer. Well, for whatever reason, I got to looking again this week and I found this thread again. Thanks to creativeevent's video link, I decided to try a test.

I disassembled the HD2 and removed the LCD/Digitizer completely, then reconnected it and powered it up (without the back cover) and it worked. Now I feel confident in risking the money for a replacement LCD/Digitizer.

The toughest part (or rather most nerve racking part) is the actual disconnection and reconnecting of the LCD Ribbon cable. Separating the motherboard from the chasis takes what feels like potentially two much force, but I did it without disconnecting any cables (I did pay very close attention to the keyboard cable though).

Reconnecting the LCD cable is definitely a trick, but I agree the once you do it for the first time, it becomes a simple task after that.

I came across this one on Amazon.

http://www.amazon.com/gp/product/B0050LU3ZG/ref=ox_sc_act_title_2?ie=UTF8&m=A1N5BNWVY8XERQ

$38 (+$5 shipping) from a company listed as being in NJ.

I have a few rewards to redeem for Amazon Store Credit before I order, but just thinking out loud, what is the biggest risk with ordering something like this from a "random" seller (I see everyone ordering from ebay, but who knows what you are getting when it direct from China?).

Just curious (and I thought I would share my experience if it helps others).

My advice to anyone skipping the complicated disassemblies and doing it the easy way, take your time and be VERY METHODICAL in separating the LCD and disconnecting/reconnecting the LCD cable. Nothing had to be really forced (even it moved/released VERY slowly).
[HD2 General] gatzdon:
Quick update on my saga.

I received the $43 LCD/Digitizer. The return address on the package was in New Jersey.

It had the same part number as mine and a connector for the digitizer cable (not soldered). There was a spot where a sticker was scraped off the back, but otherwise it did look brand new (not a single scratch and no evidence of dust).

I plugged it into the phone first and powered up to make sure it works before actually trying to install it proper. Everything worked as expected.

I then disconnected it and reconnected it routing the LCD cable correctly. I attempted to power it up again to double check before actually gluing anything back together.

Nothing.

That's when I realized that I tore my keyboard cable clear in half.

I was still able to power the phone up to make sure everything else still works and it did (my phone turns on automatically when plugged in to charge), but now I have to wait until the Keyboard Cable that I ordered comes.

Lesson learned, disconnect the keyboard cable. It's pretty easy to disconnect/reconnect and eliminates all stress on the cable.

Enjoy.

10 month cracked screen!

I cracked my screen last September, as badly as the one in the video. It's been working fine, no problem. I've been getting up the nerve to either do this, or take it in for repair. Now that my TMobile contract is up, I could upgrade but am not excited about any of the current phones. Has anyone else just used a cracked screen? For how long?

Button Strips

I have a quick question! some of my buttons have died on my hd2 and I bought a replacement off of ebay that included tools. If I want to replace my front buttons do I need a new digitizer/LCD/ front glass. Do I even need to touch the front glass to get to the buttons? If I do need to take off the digitizer do I need a new one or can I still use the one I have?
[HD2 General] :
The digitizer is glued/taped to the lcd, and it is treated as one assembly. The digitizer is glued onto the lcd, and the lcd is glued onto the chassis, so you will have to only pry off the lcd to access the front buttons. Just be careful not to rip the volume flex ribbon and the lcd flex ribbon (when separating it from the chassis with a knife, as most people do)
[HD2 General] ionbasa:
So I only have to pry off the LCD. From the chassis. Is it the middle chassis? I assume a heat gun on low should help in removing the LCD from the chassis. Once I have the the buttons replaced how do I get the LCD back on the chassis? Super glue/ epoxy / double sided tape? I would prefer not using epoxy as it would probably make it permanent. Any recommended adhesives?
[HD2 General] :
yes, you only have to pry off the lcd. A heat gun would help, I just use a hair dryer at highest heat setting for 5-10 minutes ;). To get the LCD back on the chassis, I use super glue on the four corners of the metal chassis and it holds fine. Unless you can find some tape that is as strong as the oem htc one, you will have to use some sort of glue for the lcd to stay on the chassis.

[HD2 General] daveyb123:
If anyone fixes theirs and all goes well and looks good then please write a brief post saying where you got the part from - so hard to know where to buy, and where not to buy from, particularly from UK. I need a new digitizer (295 type) or combined LCD/digitizer unit (300 type).

If you're taking the case off then use a guitar plectrum or thin but firm plastic - not metal. File off jagged/scratchy edges from your plastic 'tool' if necessary. Taper the plastic with a file or stone to make it easier to insert between the case and screen. With the battery out press moderately (not too hard) on the back of the innards near where you're working. Only lever enough to release the clips - you are not gouging out the bad bits from a potato! The phone clips in the case via small bits of the case sticking out into slots in the phone. On mine they are located as follows*:

sockets

Note: work the sides and top. The phone is designed to be inserted at the bottom then clicked into place at the sides and top. The _'s at the bottom indicate where the phone sticks out into the case (as well as the sockets).

If new to soldering - and going down the solder route, practice on an old duff circuit board - lots!, use minimal heat/contact - let things cool!, use solder wick to desolder (wick on old solder, iron on wick, use fresh wick each press) - it's v. cheap & on ebay, 'tin' connectors and iron (look up tinning soldering), clean iron on damp spong everytime before you touch your device = good connection = minimal heat through your device = parts still work/don't melt. Fleshly melt solder onto joint, don't use the old blob on end of iron where all the flux has burned off and it won't stick to anything. Use an antistatic (ESD) strap so you're not one of those people who finds parts not working afterwards, put parts on an antistatic surface (like an only silvery antstatic HDD bag or antistatic bubble wrap) - Not on the carpet! - wiring yourself to a metal radiator or waterpipe may work, but only if the metal goes all the way to the ground, i.e. no plastic pipes, Use ipa alcohol to clean rosin off it if desired, but not required-prob best left alone-no one will see it -- I'm no expert, but a few tips I know.
[HD2 General] daveyb123:
Needing to access the information on my phone with unresponsive touch screen/digitizer I have done some thinking and experimenting.

To TEMPORARILY restore the functionality: DO NOT use the 'press the power button hard/repeatedly/alternate pressing hard on each side' technique - this will only damage your power button as well.

The ribbon from the digitizer runs down towards the back of the phone just the above power button. Due to poor design, the power button likely brushes against and causes movement in the digitizer ribbon cable causing fatigue in metal in it resulting in cracks in the wires/copper strips.

Functionality of the touch screen goes on and off as these cracks (more likely just one crack) opens and closes causing the reconnection and disconnection. The best way to cause movement in the ribbon to cause the cracks to temporarily close is to rub your thumb in a circular motion or up and down on the power button to get it to touch the ribbon - you do not need to press hard.(Edit: try rubbing your thumb over the power button it in a circular motionwhile holding it down - still do not need to press hard)

To keep funtionality as long as possible, avoid pressing the power button and be careful pressing the back button - press it only straight down and gently. Keep it charged and switched on. Wake it up using the talk/send key. Don't put it in your trouser/pants pocket where the button will likely get a lot of side to side movement while walking - in fact, this may be what kills it in the first place. If you do put it in your pocket, put the buttons at the top facing away from your leg or use some kind of case to prevent the buttons receiving pressure/movement. Press touch screen only gently in that lower-left corner. If you need to switch it off, do so by taking the battery out. Switch it on by connecting it to a computer via USB. Be careful when polishing smear off the screen - avoid that power button.

To find out what replacement part you need - replacement is inevitable (unsure if this info is accurate, but it seems right)

Turn off then turn on while holding vol down to get screen with red/green/blue bars. Look at bottom right number. If it reads 0x30 its solder type (295), if it's 0x50 it's plug in type (300), if it's 0x40 I've no idea, maybe plugin (300 type) - so I read...yet to fix mine. Take battery out to reset back to normal. Most UK/EU are solder type. If it's has T-mobile on the front it's plug-in type - so I read.

Lots of positive feedback on HD2 digitizers it seems from this seller - let me know how you get on if you buy one. What is the quality/fit like? I read one seller was supplying plastic ones - not glass (but he/she said they were actually ok) - not sure if this seller supplies the same.

incompatible display/digitizer

hi there!

i've ordered a digitizer and a display from ebay,but i was careless enough not to pay attention that there are two versions.the display is the t-mobile version (smaller connector on the backside of display),and the digitizer is the other version (approx. 1cm wide connector that won't fit). is there any way to connect them?is the wiring the same,or am i better off ordering a new digitizer?

thanks in advance
[HD2 General] GnatGoSplat:
Yes, I'm afraid you're going to have to order a new digitizer or LCD. Probably better to get the digitizer because the T-Mobile style connector is much easier to deal with.

Since you needed both, I would have recommended to buy a pre-assembled LCD+digitizer because that way you wouldn't have had to worry about getting them perfectly aligned or dust getting trapped between them.

Hi,

What kind of glue have you used to assemble the digitizer and the screen?

And what kind of scotch you used next?

I think i'll use the "3M TAPE ADHESIVE"

Button Protector Mod

From my determination to find a less invasive/less risky/less expensive solution to this problem I present the button protector mod.

Button Protector Instructions

Get your phone working by holding down the power button and moving it around while trying the touch screen - you don't need to press hard - it just needs to brush against the flex cable with some side to side movement while depressed normally. Once working install Button Savior and Tap Tap apps and activate them so you don't need the buttons anymore. Tap tap doesn't always work but you can plug in the usb/charger to wake it up if need be. Anyone know of a good wake with volume keys app?

1) Find a source of .8 to 1.0 mm plastic (I used a plastic olive oil bottle)

2) Cut 2 oblongs the same size out of it to fit the bottom of the phone

3) Cut a square out of the middle of one the same size as the button panel

4) Glue both together and let glue completely dry (you don't want glue on the buttons)

5) Round corners to match phone with sandpaper or a nail file and taper the edges for a better look.

6) Stick black insulation tape over the top of it leaving a tab each side and a thin strip at the bottom

7) Place over buttons using the tabs and stip of tape to stick it to the phone - sticking it to the phone with double sided tape (NOT GLUE) might be a better solution to stop it moving around at all, although if the touch screen does happen to stop working again it's a harder job to remove the protector it to get the phone working again.

Once the phone is working and the buttons are completely protected from movement, in theory, the touch screen should stay working. I've tried shaking and squeezing the phone but it does not seem to affect the touch screen/digitizer flex cable. I'll let you know how it goes....

http://postimage.org/image/9uvf5m86p/

http://postimage.org/image/ly48bmpp1/

Note: putting insulation tape directly on the buttons doesn't work as they can still be pressed and it pulls off the brushed metal effect on them.

Adhesive tape removing

Maybe someone knows how to remove adhesive tape from lcd screen? I don't want to damage it
[HD2 General] daveyb123:
That's why I used insulation tape - easy to get off again (& comes in black)

Depends on the tape really. I'd probably try a damp coth first to see if it water soluable then pure alcohol or isopropyl alcohol first, then maybe methelated spirits which I've used to successfully remove lots of old hardened selotape glue from a whiteboard before. Obviously be careful not ot let any dribble down the side of the screen. If there's tape rather than residue to come off then you'll have to peal it but some of the above may make it come off easier. Just peal it very slowly and keep the tape close to the screen so you're pulling it sideways rather than up away from the screen - it'll put less stress on it it. If it's something like gaffer tape then good luck!

I've never tried alcohol or meths on a screen. It'll probably be ok, especially alcohol, but don't blame me if it screws it up!
[HD2 General] DOVIZ:
Thanks, i tried to use moment silver tape to remove that tape, it works good, but still there are some tape left, i will try to remove it with something like screen cleaning fluid or something, i think it is isopropyl alkochol
