Other HD2 Replacement Parts

Tools Required:

Safe Open Pry Tool

T5 Torx Screwdriver

Pair of Tweezers (optional)

HTC HD2 Written Repair Guide:

First remove the battery cover and battery from the HD2.

Now you will need to remove four T-5 Torx screws from housing surrounding the battery. Apply pressure to the area of the battery and use a safe open pry tool to release the housing from the chassis.

Using your pry tool, slide it along the outside edges until the housing is removed from the chassis, as shown in Figure 1.

Figure 1​

Remove the 5 Torx Screws from the Chassis located in Figure 2. Remove the flash cable connector from the motherboard to the flash frame camera. Use a safe open pry tool to pop the black antenna cable from the motherboard and upper board.

Figure 2​

Then remove the keyboard flex cable connector from the motherboard. Do this by using a safe open pry tool to lift up on the alligator clip, and remove the ribbon. Remove the label located below the battery.

Pop the white cable from the GPS unit located in the left top corner and work your way to the motherboard. Remove the GPS board.

Now, release the volume flex from the housing. Use a safe pry tool to remove the adhesive holding the motherboard flex cable in place.

You can now flip the motherboard and flex to the side, exposing the LCD flex cable connector. Use a pry tool to move the clip forward and release the cable as shown in Figure 3.

Figure 3​

Use a hair dryer or heat gun to heat the front of the digitizer, working in quick movements for 1-2 minutes.

Slide a safe open pry tool along the edges to remove the metal housing from the screen assembly as shown in Figure 4.

Figure 4​

Remove the buttons from the lower portion of the digitizer. Slide a pry tool in between the LCD screen and digitizer to separate the two.

You can now replace either the touch screen digitizer or the LCD screen

Now you will be able to replace any parts on your HTC HD2. Simply replace the damaged parts with the new ones and reverse the order to put your phone back together again.

Nice. You don't see many HTC leaks these days for the newer models. They must of tightened up one these things!! :(
[HD2 General] jianC:
Nice guide! In my opinion, this should be stickied..

I wish I had this guide when I first took apart my HD2 because it is clearer to me than the video

Note that you should also remove your sim card before disassembly. I could not get mine apart for ages until I realised this:o;)
[HD2 General] anonymous0612:
I had an hd2 but the screen is not responding. I want to know if this is a replacement problem or i just have to do something insidd of my hd2.
[HD2 General] repairsuniverse:
Haha yeah, it's very easy to forget about the sim card.
[HD2 General] repairsuniverse:
Thank you!
[HD2 General] Robbie P:
Hi repairsuniverse, have you heard anything about landscape mode not being enabled after screen replacement. I've heard about it in the android forums, but couldn't find why it would happen.

Hello guys!

My friend has an HTC HD2. The digitizer flax cable broke 6 months ago. And the phone is currently disassembled, and still turns on, but I failed to remove the digitizer from the LCD, so the glass has some cracks on the sides...

We are planning to revive that thing, but I'm afraid it would not last too long... So if I buy an LCD+digitizer (non telstra or T-mobile model) is it possible to protect the flex cable from the hungry power button? With what should I cover it? Duct tape? Originally some cloth was the protector, but it has been run-down...
[HD2 General] repairsuniverse:
When you order this part through us, the digitizer and lcd combo have a brand new flex cable that comes with it, and we include a free repair guide to help you out. we also have live chat support and more for our customers. please let me know if I answered your question.
[HD2 General] quailstorm:
No success...

I need some homebrew technique. And I didn't expect a company to answer. You know, after 4 years, the original clothing is like dust... and I want more usage than 3 months...

Then phone was 150 EURs the previous year, and it lasted only for 3 months. So pressing the button frequently kills the flex cable soon.

And I made a coat for flex cables in slider phones. From pure tuct tape, and it works if there is enough place. Do you need any picture to understand what do I want?

But if somebody did a succesful and long lasting protection, i would try it out. But I couldn't find one.
[HD2 General] repairsuniverse:
When I reviewed the repair guide for you and spoke with another tech. familiar with this phone, he assured me that the home button was far enough away not to damage the flex. If you'd like to send me a picture I will definitely do all I can to get you an answer as quickly as possible today. maybe within the next hour or so..
[HD2 General] quailstorm:
That's the old and damaged flex cable, I just tested if the buttons still fit in the place, but I think it's too thick. If you remind me I can provide more photos, but I think you have seen a disassembled HTC HD2, at least on images.
[HD2 General] repairsuniverse:
This black tape should not be there. It is stopping the buttons from setting in place as you put the phone back together. Please remove the tape from the screen/digi but please go slow and do not pull or cut the cable.

please replay if you need help.
[HD2 General] Robbie P:
if you use wp7 on hd2, you can remap the power and back button using new leo advanced xap

If using android there are many softkey power button mods and apps

You may never need to use those buttons again, and luckily hd2 has spare buttons;)
[HD2 General] quailstorm:
Great! Thanks!

Before the tragedy happened, but the digitizer started struggling, the phone ran WP7.8 and Android 4.1.2 in dual boot. On android softkeys were used, even for screen locking, but I am amazed to see a solution for WP too.

I hope it will last longer with the new digitizer covered with tape like on the pictures and minimalizing the usage of power button. In those 3 months, it was pressed hundreds of times, so we didn't take care about it...

I will order an LCD+digitizer in two weeks. I think it's worth 45 euros.

How should I reassemble it? I'm thinking about using double side duct tape. But if I place the buttons wrongly, it will be hard to correct it...

Currently it would fall apart, or open like a book. That's what I hate in this phone, tape everywhere...

It's the old, damaged flex you are seeing on the picture. You can't understand what I wrote? It was for testing purpose, and yes, as you say, it blocks the button. But only ONE layer wouldn't, as originally, there was a small piece of clotch on the flex for protecting it... I disassembled the phone, I saw it.
[HD2 General] Robbie P:
i wouldn't use duct tape to repair, perhaps just cloth or a plastic shield. if using duct tape and it crinkles over time, it could bend the ribbon.

I haven't actually replaced my screen, so ymmv

yes i only just realised that leo advanced remapped the power key too, it wasn't available before iirc. i tested on hd2owner's rom so it should work for all wp7.8

I am sure you will be careful with it ongoing, so best of luck with whatever your choice.
[HD2 General] quailstorm:
Maybe you are right. I already used duct tape in a W705 and in a W910 (Sony Ericssons) but those mods are less than a month old. I will look for something more useful than duct tape, but cloth is worse I think. It worns down easily.

Anyway, I haven't experienced crinkling on an unstreched piece of tape. They come off in one piece after 3-4 years. And in this place, it's not necessary to strain the tape. But I will see. I can practice on the damaged one as many as I want.

Anyway, the digitizer is useless, but the LCD works. Is there a pinout for it? To use for a Raspberry PI for example.

Thanks for helping.
[HD2 General] Robbie P:
perhaps "rucking" not "crinkling", repeated movement (of the button) on the same spot might cause it to fold and cause damage to ribbon, is what i meant. Probably won't happen though;)
[HD2 General] repairsuniverse:
I understand what you wrote Quailstorm, I`m here helping.Here is some info that should help you.

"You first talked about how the digitizer flex cable broke," If you did not break the digitizer jawbone flex holder here.

all you will have to replace is the digitizer which can be bought at

Now if you broke that and the LCD connection then you will need both.

Now What buttons are not working is it the power? or the button row? Either the case both of theses can be replaced and should fix the problem. Lets say you buy the replacement parts and the buttons do not work. It could be either software problem ( if it is Software , you can find other ways around this as the LEO Advanced as Robbie P has said. or hardware IE - Mobo is no longer working.

Yes one layer would block the buttons. The phone is made to be flush with nothing in its way. The Orignal flex cable on the did not have that. So by added it to the phone will prevent buttons not working. ( Now Understand that to add adhesive to the - say - lcd to keep it in place that can be allowed because it needs to hold down the lcd/digi to the middle plate.

Now with 'ducttape' I would say use another adhesive. Duct tape can be to thick. Should be using 2mm or 3mm black adhesive. If that can not be found you can use adhesive and cut strips.

Hope you can get your hd2 up and running
[HD2 General] quailstorm:
Both jawbones are in good condition. And I broke the LCD when I tried to cut the digitizer off with a blade... So I have to buy it with LCD.

Every button works, but it's hard to align the case and the plastic button cover. And if I stick the phone with adhesive and make a mistake... I don't want to disassemble it again. But it's mine task to assemble the phone perfectly.

I have adhesive at home. It's about 2mm thick. Itt will be good to fix the LCD on the middleplate. Duct tape is for preventing another flex cable damage. I shown you images. I will do this with the new digitizer. So the power button won't start abrasion on the flex instantly.
[HD2 General] Mister B:
Not an abrasion issue, problem is more likely due to digitizer constant flexing around the tail area. I have maintained 24 Company HD2's for almost 3yrs & even my personal device from new with minimal key usage had digitizer failure.

2mm thick tape will be no good. For perfect job on one device you probably best getting the tape from eBay. I use a little (and I mean a little) pu40 silicone adhesive added in the groove between lcd & digi after first assembled with tape as holds much firmer & gives more oem feel & remains perfectly bonded like oem too. I also use a few small half rice grain spots down sides of lcd to chassis & near corners (make gaps in tape for the adhesive spots) works well & makes finish perfectly flush, secure & firm. Also easily stripped again by using razor to cut the adhesive & scrape it off.

obviously dry run lcd/digi & button alignment before secure fixing & it worth making effort to test lcd/digi attached to mainboard with battery pressed on contacts for correct lcd & touch function before final rebuild ...
[HD2 General] repairsuniverse:
Great. The 2mm adhesive is very good to use. Sorry about you breaking the LCD . It can be a pain sometimes even on the HD2. Which is a hard phone to repair for the first time.

A good way to help you align the buttons on the bottom before you do your adhesive is to put the adhesive on it but do not take off the sticker part ( talking about the white paper ) and then put the lcd and digitizer in the phone you can align the parts right and do a "dry run" on the phone before you do the adhesive.

Good luck on this phone. its a great phone when you can root / hack it and make it yours as you want it to be.

any more steps or help feel free to post and I will allways follow up .
[HD2 General] Mister B:
Need recap on that tape 2mm wide or 2mm thick !? 2mm thick would be no good, 2mm wide tape ok.

a tweak I do on my rebuilds is raise the button board on an extra layer of adhesive tape, perhaps even 2 layers if needed, this keeps the buttons closer to the digi thus more clearance from the ribbon, I mainly do this to get more precision fit of buttons without the looseness that can be present.
[HD2 General] quailstorm:
That's what I was thinking of. So it works, thank you for confirming. The adhesive whick is at home, is 1,5-2mm THICK. And about 1cm wide. But I will look for a better solution.

But the cloth cover on the flex fell apart, and the part of the flex which is under the power button is transparent. It would be good to protect it.
[HD2 General] repairsuniverse:
3M Double Sided Adhesive Tape - 2mm you can find this on our site. this would be what you should use. I use this is my phone repairs. Its the best from what i have come to know when repairing an android/windows device. Now apple devices I use something else.

When you have the Digitizer and lcd together you can pop in the bottom buttons in to that slot on the digitizer and then put the Digitizer/LCD/Buttons on the housing. It should fit with little to no ease so you then can test the buttons on it.
[HD2 General] repairsuniverse:
I have tried the 1mm tape and I have found that its just to small to make it worth it. Because you will use more then what you need to make it stick to what you want.

The 2mm is just the right size and gives the most stickiness to the housing or lcd or digitzer depends on what you are using it for.
[HD2 General] Mister B:
Tape you have at home is no good, you want tape 2mm wide maximum & about 0.2mm thick.

Can be found on likes of eBay or OP's website. I don't find tapes alone good enough but that is up to you on your rebuild preference.

You can indeed add one layer of protective tape over the digi ribbon lcd edge, I use a high tack shielding tape mainly to add bit of support to ribbon & keep it shaped/positioned perfectly. from all HD2's I have opened I have never seen evidence of abrasion on the ribbon.
[HD2 General] quailstorm:
It looks like we three don't understand each other. Maybe because I'm not English and in school we don't learn about tech...

I will come back with pictures soon.
[HD2 General] quailstorm:
So, I'm here at last...

My adhesive is about 1,2mm thick. So it's good. I measured it. It's too wide, but scissors are invented.

On the images you can see an aluminium like piece of textilia on tha lower part of the screen. Middlepart of the buttons place, back of LCD panel. Same thing was sticked onto the flex, which is photographed in the light.

And I've got another problem, with a broken GPS connector. I will resolder it, because the first try was not very paraller with the original. Will it affect anything?

I placed back the LCD, and WinMO6.5 still boots up, with no touch.

[HD2 General] Mister B:
I would say your adhesive is too thick, it will result in screen not fitting flush with bezel edge of back cover.

example of chassis/digi tapes below:

http://www.ebay.co.uk/itm/131049200791

http://www.ebay.co.uk/itm/321114254523

Broken antenna should be ok if soldered & positioned good.

You sure the lcd cracked, most people actually crack the original digi glass which is behind the main toughened glass & then give in thus actually breaking lcd when think already ruined.

You really need look at digi & LCD & you will see 3 layers as such, heat the digi with hot air so easier slice & part & reheat as needed until separated. LCD is quite hard to break unless really rough or pry it with screwdrivers.
[HD2 General] quailstorm:
Thanks, I will look for a better adhesive. I will post photos of repairment.

The glass whick is cracked is maybe a third layer. It's beetween the LCD and the GG glass. You say it's okay to break it? The screen has still no bad pixels, it's working. But I don't wanna mess with replacing the digitiser. Too risky. I would rather buy a full pack and just place and glue it in the right place.
[HD2 General] Mister B:
Replacing just digi is not that hard & keeping the original quality lcd is a bonus & saves money.

It maybe the digitizer layer behind the toughened glass (GG) as digitizer is 2 layers if you look at it.

Most people pry the wrong layer, have a look at it further perhaps. actual original lcd has a tough plastic film over the lcd glass. gentle cutting with new razors & heating digi makes separation easy,bit of fishing line can be handy too.
[HD2 General] HTC HD 2.:
Thanks for the good instructions :)
[HD2 General] quailstorm:
It looks like I have no luck...

http://www.flickr.com/photos/quailland/sets/72157638014983736/

Here is the photoset. I removed the digitizer successfully, but the screen's flex cable got damaged :crying:

It looks like I have to purchase a TFT+digitizer combo for safety...
[HD2 General] quailstorm:
What do you think about purchasing this one? Because of the T-mobile logo, it should be an original one. But it looks like a bit scratched...

I think that I have a T8585 at home, but since it's my friend's phone, I'm not absolutely sure. Will it be compatible?

The other choice: http://mobil-telefon.vatera.hu/mobiltelefon_alkatresz/kijelzo_erinto_kepernyo_erinto_panel/htc_hd2_lcd_kijelzo_erinto_panel_touch_digitizer_1825750049.html

Then I will assemble the phone, and hope for success. It would be a big pain to fail... Also, I'm sure that we won't keep it more than a month. We can't and don't want to feed this hungry beast. He has a Lumia 520 now, and I would rather buy a nexus S. WinMO is dead, Symbian Belle is a better choice for a stable phone. So HTC HD2 can't even compete in usability. We pull out our money and go for something else.

Also, if the repairment suceeds, do you think it would be a good idea to buy a cheap but Samsung (from local shop) microSD (4-8GB), put an android 4.x on it, and sell it with that OS? I don't think anybody wants WinMO...

Currently, I'm planning to fully disassemble the phone, reassemble to try the screen again (for pratice purposes, to minimize the possible damage done to the new unit) and the disassemble and order the screen. Do you agree? (recently I broke a SE W705 by investigating if it's worth repairing...)
[HD2 General] Mister B:
Does not look like flex issue, looks more like pressure or heat related issue on the lcd.

at least you can see what I mean about inner digi glass cracked & not the lcd lens, amount of people who have thrown a good lcd away because of that mistake is a big number.
[HD2 General] quailstorm:
Yes you were absolutely right about the digitizer. But since these are pictures, and I only shown the color problems, you think it's not flex issue. But when I was moving it, the color changed, red or blue gone, or it was working. Currently it's full black...

And a heat or pressue issue stays the same.
[HD2 General] Mister B:
Maybe it is flex, hard to say without having it in hand for sure.

new pre-assembled lcd & digi is not that much more expensive, do check the mainboard lcd connector is seated & latched correctly before writing it off though.

if you get a lcd/digi combo get this tape set for easy assembly ... good luck ...
[HD2 General] quailstorm:
I still haven't ordered anything online... except a XenoGC 2.0 chip which was faulty, but was easily repairable... My credit card is not verified by paypal, but i've bought the last Humblebundle, so it works.

Do you think I could get an LCD from ebay cheaper than the 2 ones I shown you?

I am really afraid now that I will just waste more money on the phone... I lost my hope beacuse this goddamn LCD.
[HD2 General] Mister B:
Here's a LINK for one on eBay with free shipping to Hungary & good feedback ...

Rebuilding with prebuilt lcd/digi is quite easy as long as you not broken anything else.

You will need tape like in link in post #49 or you will need cut you own shaped padded black bits for top & bottom of digi.

If selling I would sell with WM6.5 & let buyer sort out what they want, I wouldn't buy an HD2 with obvious WP7 or Android flashing as normally they are faulty or close to death due to OS's pushing device hardware much harder.
[HD2 General] quailstorm:
Thanks for the link. That's really cheap, and I think it's not an original HTC product. We will see if it's worth to buy an original part if we can.

For the operating systems:

You are a tech guy, an expert. But most people aren't. So they won't search for WindowsMobile device, and maybe don't know anything about the glorious HD2. But if it's advertised with android as a freshly refurbished device, I see more chance. Most people I know are afraid of bricking the device, some of them not even installing the regular updates to their phones...

But this is really far away. I will post if got further with the HD2. Thanks for everything!
[HD2 General] Robbie P:
I know this is getting OT, but I agree with Mister B

I got another (secondhand) hd2 fairly recently with wm on it and it had no bad blocks at all. If it has android or wp7, then the nand has been erased and written over god knows how many times, so a phone with wm on it seems a better prospect for me.
[HD2 General] Mister B:
You would be very lucky to get a real htc product even if advertised as genuine & as the original htc digitizers are not the best you have little to gain & just more money to loose.

Digitizer & screens in that listing are good, use to be twice the price but due to age of HD2 & slowing of sales prices have come down drastically, I paid 10USD per digi for current stock & they work & fit great, have copy well fitted digitizers that have outlasted originals ...
[HD2 General] repairsuniverse:
You're most welcome. :)
