EVO digitizer on HD2, is this possible?

There was some talk about the buttons on the HD2 going bad due to much use on android ROM. Was wondering if Evo digitizer will fit/work on HD2? That would get rid of the possibility of buttons going bad.

To engineer that would be SIGNIFICANTLY harder than just buying the part for the buttons on the HD2 and installing it. Phone parts are not interchangable and if you've ever opened one up you would know the answer to your own question. The talk about button problems on the HD2 is over exaggerated. First you don't know what the people are doing that are starting those discussions - how hard are they with their phones, etc. The keys in most phones are pressure contact switches - they are designed to perform for years of normal use not used by a gorilla or someone who isn't exercisiing care.
I've owned HTC phones like the TYTN I for a number of years and used the hard keys - very similar contact switches - never a problem. The same for the 2125 which was a Windows phone with hard keys only. They were very small and I used the phone for two years every day. Keys did not wear out and they felt about the same as when I bought it.
Don't worry about it for at least two years of general use. Even when using Android you can get widgets that mimic soft keys (ie. the back/windows key).

Stim, thanks for your thoughts. I purchased a HD2 with a broken digitizer and replaced it so was wondering if the digitizer on the EVO would work since they are the same size. I did get a chance yesterday to see a pic on the internet for the EVO digitizer and the ribbon on the EVO for the capacitive buttons and digitizer does not look compatible size wise on the HD2.
I've never had buttons go out on any of my phones before. With all the talk of the buttons going bad I thought maybe it was a quality issue with the HD2.

I might be completely stupid here, but what does the screen/digitizer have to do with hardware buttons?
I thought the digitizer is just the touch sensor of the screen, and that the hardware buttons have their own button pads/switches (whatever they're called).
Now, if you were talking about capacitive "hardware" buttons (such as the ones found on many Android devices, like the Nexus1), I can see how the digitizer would come into play.

while on subject of digitizer of hd2, does anyone know how to replace it?
I recently dropped my phone on the ground and even though i had a scratch resistant film over it i broke the glass digitizer, phone digitizer work 100 fine but i would like to replace it, honestly i got lucky that i did not damage the lcd screen under the digitizer, i have priced replace ment part at about 60 with tools to fix it, i would just like advise to get repairs done

Actually you aren't so lucky. There are plenty of threads on this issue. Replacing the digitizer and lcd as separate components is nearly impossible without damaging the lcd. Hate to be the bearer of bad news. Separating the glass from the LCD is nearly impossible. They are glued together and air sealed. Some have tried and failed by either destroying the lcd or making the phone inoperable. HTC either heat seals the two together or uses a special adhesive. In either case unless you are working in a class clean room (no dust) getting specs, skin or hair more than likely and you will be really ticked off to find that crap in there when you go and turn the phone on. Mike Channon's website used to post official (semi) HTC maintenance guides but the HD2 hasn't been posted. There are however a couple of Russian links that go through the process. The HTC guides were much better and they listed the steps, torx settings, oven temps etc..
I've seen a few on eBay - new but there seems to be some that need to be soldered and others that don't.
My suggestion is buy a complete unit if you have to or sell it damaged on eBay and get another phone.

i can also buy a lcd and digitizer together to eliminate the hassel of having to seperate them, and install componients like that, only downer is prices avererage 100-120 dollars, would that be a good option? i have seen videos on youtube on how to go about replacement, im quite knowledgeable about wire work and sodering but do u think im getting in over my head by tring to do this repair?

i know buying a used hd2 is about 575 and it only goes up from there, i just dont have that kind of cash right now, plus my phone is unlocked, has hard spl, running nand android flashed directly to phone, with att service fully working, something very few owners have accomplished with there hd2's..

I notice the hardware buttons are not included. My phone is fine except the hardware buttons were scratched up after suffering a hard fall.

I don't know. I've done complete overhauls on TYTN I and TYTN II's. They didn't require heating to remove the panels - they just snapped in. Phones were very modular no work involved except screw removal. The latest phones seem to be held together with some sort of adhesive. I remember looking at how to disassemble a FUZE. Major pain to remove the screen from the keypad - required an oven to melt the glue.
Look for a complete quide that shows step by step disassembly AND assembly. Sometimes they forget the tricks to put it back together and you get messed up.
The 150 for the housing seems a little steep. But most of the LCD/DIGITIZERS are at least 100. Be careful about some of the parts they are stripped from a "working" phone - doubt it - why would someone take a perfectly good phone and break it apart for the parts? Doesn't make sense - they can get more money for the complete unit. Sounds like they were defects or seconds - screens may have dead pixels or spots. I'd look for factory fresh new stuff personally. You can buy the keypad/keys separately on eBay for next to nothing.

The digitizer is the glass that you touch when operating the phone. The LCD panel is the part that shows the pictures. The digitizer covers the LCD and both are sealed together. The TYTN series of phones did not have this.
The OP was concerned about replacing the digitizer without harming the LCD. I know from experience that this is very hard to do. I managed to get them apart and replaced the digitizer on my HD2, only to damage a single line in the LCD when I re-assembled the phone. It was a complete waste of time and money.

Actually, the housings sold 3rd party are usually factory fresh, unless specified otherwise. HTC expects to have techs replace various parts of the phones and ordered a certain percentage of these types of parts. When the initial sell drive dies down, the excess is unloaded to 3rd parties who either offer them up on sites like eBay or catalog them for companies that repair phones.

well like i was saying would it be easyer to buy both the digitizer and lcd already together and just replace the ones in my phone?

[Q] Tmo G2 No video issue (Self-replaced parts)

So i've read through the stickies and havnt come across anything really substantial, tho I have seen a few other user posts about their G2 suddenly losing video.
That's the issue I'm having.
Here's a little history for you:
Customer brought this phone in to me, said it had water damage. Bought it off them to tinker with myself. I opened it up, and sure enough there were some water stains on the flex cable and the back of the LCD. I replaced both with brand new parts, and now the phone boots, but has only a black screen. It receives calls, touchscreen works, makes clicking noises, all that jazz.... just no video
I've pulled all the rf shields off the logic board to take a peek under them, and there is no water damage at all on any part of the logic board that I can see. LCD and flex cable (and midframe) are all brand new, and I'd really like to get it working!
Somehow I dont think HTC will be willing to warranty this for me (tho I have replaced everything that had water damage, so it should be undetectable as there weren't any water stickers in the phone for some reason)
Thanks in advance!

well, after taking a long google walk, I decided to contact the manufacturer of the LCD I bought and try having them replace it for me. hopefully that is the issue and not one of the chips on the main board or some other cable i missed.
If it IS a chip on the board, I'd love for someone to point it out for me so I can try a reflow. Dont wanna reflow the whole board cus it's still got the internal stickers and I dont wanna damage them in case I can finagle a warranty replacement out of HTC

so does anyone have any other ideas what may be behind this issue other than the LCD? I dont want to have to wait to send this LCD back and get a new one, especially if the LCD isnt the problem

I'm not 100% sure about HTC phones as I have not opened one up yet, so i'll speak with my experience with BB phones instead.
When I was in the process of replacing the LCD screen of a BB Storm, there were 2 different types of LCD screen for one device. Perhaps this could be the case? In the BB case, there was a part number followed by either a 001 or 002, neither of which were compatible with each other. My assumption is a driver issue with the main board.
It's a small and simple thing to overlook, especially if you have prior experience in doing things like this, but I thought it would be worth noting. I would compare the old damaged part with the replacement part and make sure the part numbers match up. If the replacement LCD is from China or Hong Kong, I would be weary about their quality.
Regards.

well I got it on ebay, but it was a California seller. as far as I've been able to determine from looking at listings, the LCD's for HTC Desire Z and G2 are identical. All the clips match up right, and all the ribbon cables looked identical to the one I pulled. I'll look into checking on this a little more in-depth tho so thanks for the info!

Hey Bro,
did you managed to fix your phone? I just changed LCD twice, but still the same it boots and all but no video on it... You can even call it, answer everything else works but the screen... Im thinking to change the FLEX RIBBON CABLE, but after reading your thread not sure if thats going to fix my problem. With my original screen I had no backlight on the LCD with the replacement I got backlight on the LCD again...
Any suggestions, ideas welcome!

Screen damaged, touchscreen not working

Ok, I'm a complete idiot and let my Nexus 7 fall and now I have a hairline crack. At first I thought it would be fine, since it is a very fine crack - almost unnoticeable, and the Nexus didn't even turn off. The screen looks fine but, alas, the touchscreen is not. I get no response at all. This does not appear to be the first time this has happened (a quick search on Ebay turns up several damaged Nexuses being sold for the exact same reason - A shame no-one is selling a damaged one which still had a working screen).
My question is (since I know you cannot simply replace the touchscreen elements, you have to replace the whole screen which is probably not worth the time and effort compared to buying a new one) is it possible that the touchscreen controls came loose or something such that it could be fixed, or is it tied into the screen so since I have an image it must mean that the digitizer is ruined. I hope something can be done, especially since something similar happened to my Galaxy Note a month ago and it has a shattered screen (way worse than the Nexus) but it's touchscreen still works just fine (maybe someone should keep me away from tech, this keeps happening...). Or do I have to accept my fate and lay my Nexus to rest.

Corning FIT Glass is a new product that is rather interesting. It's a much thinner section of glass with high scratch resistance and is pretty strong in respect to it's thickness/thinness. A product spec sheet shows it close to but not the same as Gorilla Glass and likely due to the thinness in comparison, but deffinetly superior to the standard Soda-Lime Glass formula used by many.
The key features of Fit is that the digitizer and glass are bonded together and is then bonded to the display for an complete "airless" display. I'm suprised Google doesn't make more of this as the Kindle Fire HD is making a big deal about their display tech. Pretty much the only difference is the display "cemented" to the back of the Corning Fit Glass/Digitizer product.
So when it all works, it provides a display result and responsiveness you didn't experience with the older technologies.
BUT.. When it does break, the digitizer being directly bonded to the glass is also broken. So you see the trade off for the new technology. No air gaps between the components prevents the possibility of a screen protector to "hold it together" and allow you to still use it even after the display is broken. So once broken, the display is useless. I believe the technology is sound, but the application used by ASUS in the manufacturing of their tablet may be exposing the edge of the display as that seems to be called out in the spec sheet. I'd push ASUS support hard on this as a manufacturing defect and try to get a replacement.
Some examples of the technology:

Dead screen on Galaxy S4

I bought it about 9 months ago on Craigslist. I'll never do *that* again.
After I got it home, I noticed that the screen looks as if it has been replaced. A tiny bit of glue in the upper corner. Oh well. It was working fine. Or so I thought.
A few weeks ago, I started getting these strange vertical lines through the entire display. I couldn't figure out any pattern to it (time of day, temperature, etc.) It would usually go away within a few minutes.
Then today, I hit the power button to bring it out of "sleep" mode, and the screen flickered a few times... and died. I tried to power it back on; no dice. I pulled the battery and tried powering it on; no luck.
I plugged it into an AC charger and at least I saw the battery icon. I powered it on, and the screen flickered and died again.
Is this a known error or a simple fix? Do you need more information?

Sounds like a dead display, not a real common problem but it happens. You can replace the display which is not a huge deal but my concern is the glue you mention. That may make it a bit of a challenge to repair. Depending on what type, how much and where glue was put.

How much would a new display cost if I replaced it myself? How do I know it's just the display, not the digitizer or something else, etc.?

Check Ebay. Ebay is usually loaded with replacement screens/lcds. If you do buy from there make sure it is a Sprint variant of the SG4. There are suttle differences on the inside between GS4s. The lcd is the part you'll need to replace if necessary. I would advise, taking the display off first to inspect what the previous owner had done. It's entirely possible that the lcd cable ribbon is loose or not seated properly to the board.

The display will be the outer glass, digitizer and LCD all in one package. You can try to replace parts separately, but trust me it is not worth it. The outer glass is glued down to the digitizer, that is a real pita to get apart clean without damaging what is left. Then if you do manage to get it apart it may not function as well or be as durable as originally because the outer glass no longer makes contact with the whole digitizer. Think of it like a single piece of wood vs a laminate like plywood.
Granted it may not be the display (there is always a possibility it could be something else -like aliens) but most likely it will be the display. I would think of it this way- try to replace the display, if that does not work you can resell the display you just bought and you might be out $20- well worth it in my opinion.

Thanks for the info. Looks like the glass/digitizer/LCD will run me about $100, so I'm not sure it's worth it.
Does anyone have the link handy for the Galaxy S4 drivers so that I can get what I need off the phone?

I've followed instructions to take the motherboard out and put it back in. Is it difficult to ge the display off? Is the LCD cable ribbon easy to find?

LG V20 screen replacement!!!!!

Hey guys. I recently broke my LG V20 (AT&T varient.) It is just the top screen and not tbe LCD Digitizer. The 2nd screen is completly fine and its the main screen that's broken. Does anybody know a good tutorial and a good source to get tbe part ASAP?
Thanks in advanced.

As someone else said,youtube.
In the amount of time waiting for a reply, you could have just Googled the question.
And, the second screen, I do believe, is a single physical screen, partitioned by software. If one is trashed, both are I believe.

Thank you. I understand Youtube and Google. The problem with that is there are only like 3 videos, and each video the process is slightly different. When I try and search for the part, I find the glass/LCD digitizer ranging in price from $100-130. This is fine but the problem is I don't want to wait a few weeks to receive it, since all of the places I've found that sell it can't do expedited shipping, and if they do, they are all sold out. Lastly, I also found JUST the top layer of glass (no not a tempered glass protector, the actuall replacement) for only around $10-$20 in price, but there are ZERO videos on Youtube for that process, and a few people in the comments have even asked about this, with no luck.

A combo of multiple things....
This is a relatively new phone. Won't be lots of how tos available for one.
Second, what you are asking about is not a simple fix.
It requires either extreme cold such as, liquid nitrogen or 90% alcohol and dry ice cold. Or extreme heat. You either embrittle the glue with cold and peel it off in pieces or soften via heat and pull it loose in pieces. You run risk of killing your digitizer. Plan ahead accordingly.
You also *will* kill the polarizing layer in between digitizer and glass. Be prepared to replace this as well. Anyone who says otherwise is fibbing, IMO.
Then, you need something to remove the bubbles from the LOCA glue and gorilla glass sandwich.
Then reassemble.
Again: with the phones age, and a small supply chain in place due to the devices age, don't expect much in the way of how tos, or parts.
tl;dr
Not a simple fix. Chances are high you wont get it back to stock without a good technique and some moderately expensive tools.
Edited to add... There's a reason you find very few glass sellers, and lots of people selling digitizer/glass combos. .. The odds of a ****ed job are sky high, esp with phones with curved glass, like Samsung garbage.

On my V10 my front screen had cracked. Rather than try to replace just the digitizer I bought a dead V10 on eBay and replaced the full screen housing from that phone with my motherboard. Much easier to replace full screen assembly if you can find that way.

I have a v20 Sprint..My Screen Is Cracked Some What At The Top..Will That Crack Cause The Phone To Freeze Up?
like Sometimes The Phone FREEZE BAD but when i press the screen I can still Hear The Sounds from the apps

Fixez - LG V20 Screen with Frame
Just thought I would "help" other LG V20 owners; but I just finished replacing the screen on mine after dropping it on the concrete floor in the parking garage at work. It actually landed face down and I had a crappy Incipio case, so it was a spiderweb of cracks although it still ran fine for 3 months until the lines got thicker and thicker.
Anyway, I ordered a replacement Screen with Frame from Fixez.com and just know that it is NOT OEM or even close. I got my phone working; but just some notes for anyone else who finds this and tries to replace the screen themselves.
Most YouTube videos out there are NOT accurate and you will end up having to "move" extra parts they do not show.
I got the FRAME replacement; but I think it would have been BETTER without because all the tiny pieces are GLUED onto the frame.
You MUST have the tools, especially that tweezer one and get a Hair Dryer, because the parts are TINY and GLUED so easier to loosen.
I broke the Headphone Jack, because the connectors are basically membranes, which is why I think you should just replace SCREEN.
I forgot to clean my front facing camera; but I cleaned the two rears ones, so just make sure you "alcohol and air spray" clean before closing.
It is beyond blurry and I do not want to take it apart; but it could actually be the "low quality" peephole, which is creating "flare and blur".​
Once I finished and turned it on, I was overjoyed; but after a week I can "see" more problems and just be aware that you really need OEM.
Problems:
Secondary Screen does not "show" when Main Screen is OFF; but it worked with original screen once option enabled.​The top part is not white-white; but just a "hair off" and it is like an "oval thumb circle" and might have been "touched" during manufacture.​Put some Arctic Silver CPU compound; because this "knock off" runs HOTTER and the first few boots felt like a "burn in" sequence.​There is no LG Logo at the bottom of the screen; so if you decide to "sell" it later, then it will be obvious that you are selling "refurbished".​The battery seems to drain faster; but I also noticed it does not "like" a FULL charge and runs nice and cold when lower battery charge.​Headphone jack broken. Does not light up when I look at screen. Sometimes "double tap" (KNOCKON) does not work correctly.​Sometimes I have to press Power Button twice to turn on screen. Sometimes it is once. Basically "sensors or integration" seem to have issues.​I just miss how the "little things" used to work perfectly, even when it was cracked.​
Basically, this screen feels like a cheap Chinese "knock off"; but I went for the "cheapest option" I found out there and you get what you pay for, so it works, but I hope this helps someone else out there to make an informed decision. Remember, Fixez (and ALL OTHERS) have a NO RETURN policy; because basically they state that it must be in NEW RESELLABLE condition and you are going to be sticking things, bending wires and removing plastic tabs. So do not listen to anyone and these repair shops will NOT return your money once you try to DIY.
If I had to do it again, then I would have spent more time looking for a screen with the LG Logo and at least try to get something with some OEM "guarantee or promise"; which Fixez NEVER made and I just went for Low Price and USA Based. Might have been better to get something OEM from Asia; because I got ganked anyway and I suspect this screen is going to shorten the lifespan of what was a beautiful LG V20 - H918 from T-Mobile.
:crying:

Does anyone know how to find a decent quality replacement of the glass and digitizer? I'll certainly keep the ease of 'no frame' in mind. I would like an oem product for sure. But I want my phone back asap, so I'll take what I can get
