OK, so I dropped my phone and the LCD went out, I hooked the phone up to the laptop and the phone still works fine, even the touch screen works. ( I used My MObiler to see phone screen on the pc).
I bought a new LCD screen off of Ebay and replace it, now, the LCD screen works, but for some reason, the touch screen stopped working.
When I took the LCD apart from the touch screen, there seem to be a layer of grease of some sort between the touch screen and the LCD. I wiped it off with a lens cloth, don't know if that caused any problem.
Also there is a dark film (tinted) glued to the touch screen when looking from the back, what is that for? I looked at replacement touch screen on Ebay but none of them have the tinted film layer. I've search all over the internet for instructions but can't find any.
So my question is, what are the correct procedures for replacing the LCD screen and the touch screen (digitizer) ? Also after I installed the new LCD screen, the screen is very reflective and the glare is really bad, how do I fix that problem?
Thank you experts!!
You should have replaced both the LCD screen and the Digitizer. There are complete kits on ebay as well as instructions/tools to complete the replacement. Did you purchase the digitizer also?

I went ahead and purchased the digitizer by itself after the original stopped working. Hopefully, it will get my phone back to normal. Thanks for your reply!
in the wiki theres disassebly instructions of the device that should help you (but you probably already know that since you've already switched out the LCD)
In my experience, i have never replaced either the digitizer, or the LCD by themselves, i've always bought LCD+Digitizer and replaced them as one. Seems like the Digitizer is usually glued onto the LCD and i never wanted to mess with that.

I should have ordered the kit instead of just the LCD. What lead me to order just the LCD is when I hooked the phone to my pc and confirmedthe digitizer still worked. And since this is the first time ever I disassemble a phone, I assumed the two things were separated.
But my digitizer should come in tomorrow so I'll just have to wait and see. Thanks for the info.
where did you find a guide to take apart the TP2? I just had the unfortuante luck of smashing mine in the car door as I got in....it fell out of my pocket the exact moment i was closing the door....
My screen is shot, but other than that the device appears to work. I can power on, and try to dial after I press the hard key for the phone pad. The touch portion seems to work, but from your luck, I guess I am looking at having to replace both...
anyhow...any advice on guides and how to find the stuff on the ebay would be apperciated.
I still have 18 months of a 2 yr contract....sucks....and it sucks doubly becuase i just took the insurance off last month....grr..

Here's a photo guide of the disassembly of a Rhodium (TP2), it might give you some insight. There's also been a number of threads in this section about hardware parts and the screen/digitizer in particular, listing places where people found/ordered replacement parts.

The disassembly instructions are here: http://translate.google.co.uk/trans...ka/htc_touch_pro2/&sl=ru&tl=en&hl=en&ie=UTF-8
I did not follow those instructions since I did not want to open the back of the phone.
What i did was I tilted up the phone and used a very small screwdriver and unscrewed the two screws from an angle (it worked).
Then I pried the back of the tilting part of the phone all around to reveal the inside. Be careful not to pull too hard on the flat cable since it's still attached to the back (body) of the phone.
The LCD and touch screen are glued together (I didn't know that before). At this point I would remove the tape that is attaching the flat cable to the back of the LCD, and also lift up the clear yellow tape and detach the three connections.
The widest ribbon is from the LCD, the medium one is for the 4 hard buttons in the front, and the little one is for the touch screen.
I would suggest wearing some sort of anti-static wrist strap (I think I fried my touch screen along with the flat ribbon that is attached to the phone while trying to replace the LCD without anti-static wrist strap).
Once the whole tilting part is freed from the phone, I would carefully push the whole screen (digitizer + lcd) out from the frame, again, they are glued to the frame but can be removed fairly easy.
That's it, the install is reversed of removal and hopefully yours will work again.
Like I said, I think I fried my flat ribbon so after replacing the Digitizer (it came in today), the touch screen still doesn't work, so now I'm looking for that part, I'd appreciate a link to it if anybody knows where to get one.
Oh, and for the parts, just do a search on ebay for "touch pro 2 lcd" or touch pro 2 lcd + digitizer"
Gook luck with your phone!
What tape to use to stick digitizer back to inner bezel/chassis?
Hi - i got as far as trying to replace my Digitizer only to find that the LCD was stuck to it too. So as clever as i am (not) - i tried to remove the LCD off the digitizer - but that just ended up cracking it.
So i'm in the process of ordering a LCD with the digitizer - pre-stuck together (i hope!) - but my question is:
When i removed the digitizer off the front bezel, there was this spongy sort of double sided tape... i assume it was used for a reason and not just any ordinary double sided tape (presumably to allow a bit of leway between the digitizer and the bezel when pressure is applied to the touch screen)...
Any thoughts on what sort of tape this is? - here's some photos of my digitizer and the bezel:
zedii.co.uk/DSC_0002.JPG
^some of that tape is left on the digitizer... it's the black spongy stuff...
zedii.co.uk/DSC_0003.JPG
^i cleaned (removed residue of sticky tape) in the inner part of the bezel where the digitizer would stick...
Any specific tape to use that anyone knows of?

I wish you had asked before you ordered the digitizer + LCD, since I ordered mine separately, and they seem to both working ok. The digitizer does not have to be glued to the LCD. But anyway, I just used plain old Gel superglue to glue the digitizer to the bezel. I used Gel superglue so it won't run into the electronics beneath. Things seems to work just fine now.
One thing to consider when you crack open the whole phone though. Be careful not to loose any part from within the phone, because apparently, I lost something, now my accelerometer doesn't work, and my screen doesn't rotate when you slide out the keyboard. Hope it works out for you!

Thanks for the advice adp9626! Well in summary I think I've just been messing about too much and being stupid really.
In the end, I managed to just remove the top part of the screen without actually having to break into the bottom section of the phone.
I was a bit concerned about the whole sticking of the LCD to the Digitizer part. I actually did purchase them separately, however I was not sure what kind of glue was used to stick them both together - as I recall it was a nightmare to try and remove the LCD off the old Digitizer.
So I returned both separate parts (got a full refund as I didn't use them) - and now I am looking to purchase both parts stuck together.
I'm waiting on the guy on eBay to confirm that they are both stuck together. I'm also thinking of using double sided sticky tape to stick the Digitizer back to the inner bezel...
So that's the final plan! I've been a bit silly in rushing with ordering parts etc. but I just want to be on the safe side now - well - at least with the LCD stuck to the Digitizer part.
I will take your advice on the gel superglue if the double sided sticky tape doesn't prove it's stickyness!
Thanks
Zayd.
Can anyone help me find the lcd screen and digitizer as a single unit for Sprint? Everyone I find states not for CDMA.
Thanks
Anyone ??? I spent an hour on google and still came up with no leads.

I ordered one from this guy and it works great. it comes with the entire top half of the phone and the keyboard. There is only one left so you may want to hurry. Link: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&Item=270583335455&Category=20336&_trkparms=algo%3DLVI%26its%3DI%26otn%3D2
Edit: I wanted to add that they're are slightly used so there will be scratches. The one i received is a little more scratched than my original then again the scratches aren't noticeable when the back light is on and you're getting a working screen.
Just my experience, I had a faulty LCD, digitizer was OK. Bought a replacement LCD off ebay, delivered from China but only cost me £20 inc delivery. Arrived with tools as well (T5, T6, philiips, and pry tool). Followed a couple of disassembly instructions online, took me a while to get all apart but managed it. None of the instructions online go through actually taking the screen out, I thought I'd messed it up as I took the back half of the LCD off and left the front bit on, and I couldnt get it off at first. I ended up using a very sharp scalpel to slide between the LCD and digitizer and got them apart eventually, as I didnt realise that they were glued.
Anyway, I just placed the screen on, no glue as there is a ring of sticky tape around the back of the digitizer which holds the screen in. Connected everything back in the end and its working fine. Only prob is I think I damaged the power/standby button, so be careful when around this area.
Touch Screen not responding after replacement
Recently, I replaced a glass screen on a SGH-M919 Galaxy S4. Previously, during the process of cleaning the glue residues off the LCD screen; I rubbed it with rubbing alcohol and it removed a small streak of the adhesive glue off left side of LCD screen and bottom right corner. After installed the new glass screen, I noticed a few spots of the glass screen wasn't sticking onto the sticky layer. So it looked like it has big air bubble between the glass screen and LCD. And I could see the rubbed off streak on the LCD screen. Everything worked fine with the new glass screen, with the exception of seeing the streak and bottom right corner rubbed off.
A few days ago, I had a table clock fell on top of the phone and broke a piece of glass. Nothing happened to the LCD screen and still functional 100%. So I got a replacement glass screen - the same as the first time replacement. With noticing of the rubbed off streak and corner of the adhesive layer on the LCD screen - I decided to rub off all of the adhesive layer from the LCD. I sprayed some Goof Off liquid on the adhesive layer and left it over night. Next morning I continued scraping off the glue with a small plastic card. Cleaned off all glue residues and examined the LCD screen for any scratches or damage. There was none. Re-installed new glass screen - but now the touch screen does not respond to the touching on the icons. Only the Home, Menu & Back touch button work. I was baffled after this.
Could it be that because I left some the Goof Off liquid on top of the LCD screen over night and it might have leaked to the other side and shorted out something? I saw a few forums that suggested a Factory Reset. I did that - but still didn't work. Please advise on what I need to do to fix this problem.
Thank you in advance for the advise or suggestion.
So you know that these are the TP2 forums, and no one has used this thread in the last 3 years....right?
LCD digitizer replacement.. now black screen
I saw the for replacing the LCD-digitizer of my nexus 4 phone, and followed the steps carefully. After I placed the battery, I checked to see if the phone turns ON and the display is working before I complete the last step of putting the back coverplate. I successfully switched it ON, saw a perfectly working screen, and browsed through my apps. To complete the assembly, I put the back cover by gently pressing the frame along the edges, but suddenly I saw some yellow green lines in the middle of the screen. I switched it off and again switched in ON, but now the entire screen had light with no display.
To fix this, I tried again checking all connections but no luck. What could be the reason for the sudden loss of display when it worked perfectly fine moments ago? Is there a possibility that I damaged the LCD while putting the back cover on the phone?
I am also not sure about one of the ribbon connectors of the digitizer. There are 2 big ones which are prominent and has ports to connect. However, there is a little third one which also has to come through the gap but doesn’t connect anywhere. Has anyone also experienced this while replacing the screen? Any help will be appreciated.
I have hardware version 0003, the display works fine just the top glass got cracked, can someone point me in the right direction for a new digitizer assembly? I found one on amazon new for 24$ but have no idea if it will work for my phone.0002 vs 0003 I read have different ribbon cables.
Sent from my EVO.
When this happened to me, I couldn't tell that the LCD had also cracked. I bought the digitizer only, and when I took apart the phone, I realized that I didn't have the parts I needed to fix it.
I can tell you that the correct P/N for the Novatel screen is 2V6A, but I am not sure of the P/N for the Epson screen. Check which screen you have by adjusting the brightness.
If when you adjust the brightness it switches with a fade effect, then you have a Novatel screen and you need the 2V6S ribbon. However, if it switches quickly and suddenly from one brightness setting to the next without a fade effect, then you have an Epson panel and you need the other ribbon cable.
So, I know it's been posted a lot in other places but I couldn't find like, a definitive answer as to if there are different digitziers? Am I just confused?
I would like to try and just replace the digitizer and glass over top of the LCD, my LCD works fine, the cracks are really thin and only a few going across diagonally. It fell from maybe 2 feet off my lap onto a parking lot surface.
I understand there is two LCD pannel types like you said, but are there two digitizer types/sizes?! for that ribbon cable.
I'm completely comfortable with taking it apart, I'm just worried I'll get the wrong part and find out the screen is also cracked and have to end up not using it for days until new stuff ships.... bleh
I've found digitizer+glass on amazon for 24-30$.
How do I adhere it to the LCD though, says doesn't include anything to do that.
EDIT: Found this gem: http://www.durapowerglobal.com/HTC-EVO-4G-Digitizer-Adhesive-_p_1166.html
Adhesive wont be a problem I just need to know about the glass/digitizer
EDIT2:
OKAY, if you want to ignore all i've said so far here is my real question of what I need to know.
http://www.durapowerglobal.com/HTC-...iginal-With-Installation-Adhesive_p_1103.html
Is there only ONE digitizer/glass piece on any given HTC EVO 4G? Or is there two different types like the LCD?
Hi, has anyone replaced their digitizer on their desire z/g2? How did it go? It looks easy on the youtube vid.. have any problems? What way did you use to melt the glue? What digitizer did you use, where from?
Any info much appriciated as will be replaceing mine v soon due to 'invisible finger problem' that's driving me nuts..
Thanks..
Sent from my HTC Vision using XDA App
Never done it on a g2 but should be pretty straight forward especially with a video lol. Use a heat gun to melt the glue, pretty much the only tool you SHOULD use to do something like that.
I replaced the digitizer on my third G2 after getting a refurb replacement from T-Mobile that had a black spot inside the actual digitizer glass, not on the outside or inside.
The process is very easy with the video, however, trying to keep dust and fingerprints from getting on the inside of the phone while you're trying to get it back together is a serious pain in the rear! If it's the same video that I watched, just use a hair drier blowing hot air to heat the adhesive on the inside of the digitizer and then pop the digitizer off very very slowly, because you don't want to accidentally bend the metal bezel around the screen.
You also may want to leave the original leftover adhesive on the inside, because when I cleaned mine off, light now always leaks out around the bottom edge of the digitizer, below the menu, home, and search buttons, even though I used the double sided adhesive strips covering the entire length of the bottom, so light shouldn't technically be leaking out. No biggie, though... it works like brand new, now!
Thanks for the reply.. I have seen that video and that's what I was using as a guide.. I ordered the digi today, should be here tomorrow.. the only thing I was wondering was the glueing process, as I have not ordered the double sided glue/tape stuff, as I was just hopeing to still use the original glue as I think you are saying.. I hope that works! Have to be careful like u say with dust/fingerprints etc..
Sent from my HTC Vision using XDA App
Hmm, after reading your post again, maybee I should of bought the double sided tape afterall? Do you think the old leftover glue is enough for the new digi?
Many thanks..
Sent from my HTC Vision usingall XDA App
Run over to radio shack they must have some kind of glue you can use lol. google cell phone screen glue see what info you can find.
Ok, just incase anyone is interested, got my new digitizer, followed the video, used a heat gun cerfully to melt the glue, pulled the old digitizer out, and used the original glue whilst still warm to hold the new digi in, as all of glue stayed on the case rather than on the digi, which was pretty lucky.. put it all back together and everything perfect, touchscreen back to how it should be.. cost me 17 pounds.

How was this accompilshed?
I replaced the touch screen as well and the problem persists. Plus I never ran into a part that required a heat gun did I use the wrong item?
A VERY confusing part is getting the midframe to hold to the hinge mounts. The side (black dots all down it) should overlap the stabilizer bar on the hinge. I fidgeted with it for hours until realizing it goes over, and inadvertently damaged the highly sensitive LCD screen, which resulted in me taking the whole thing apart again to replace the LCD and digitizer. UGH!
DO NOT get the cheapo digitizer on Amazon, look for one with gray spots where the menu, home, back and search keys are on the back side. The digitizers without them will not work when you swap over the white button caps on the back. I feel like this information is vital to anyone who is replacing their G2 digitizer, but most guides and videos make no mention of it.
I used a lamp to heat up the glass to remove it the first time. Took too long the second time so I used a hair dryer.

Hi, I did buy mine from amazon.co.uk, there were a few for sale,, the one I bought was supposed to be a genuine t-mobile g2 replacement (refurb I think, pressumably this just means that it was from a second hand g2 that had problems and the digi was taken out - and I'm pretty certain this is the case as mine has a thin film (which u leave on) over the back of the digi covering the tracks etc, which had a few very small air/dust bubbles under it (just noticeable when screen off), where I own a desire z, so now it sais t-mobile instead of htc, but I can live with that.
The small grey bits that you talk about were floating about or stuck on my digi when I pulled it off the main chassis. I had a look, and as far as I could work out, were possibly just for giving colour to the tiny led's that give you light to the home/search keys etc (I may be wrong on their use), but if you look closely, the tiny grey things have even smaller rectangles on them that relate to the positions of the led's on the circuit board. So I picked the remaining ones off the old digi, put them back in their correct holes and stuck the new digi in. I've had no problems (with a digi from amazon with no little grey things on it) so far, but maybee this is due to mine being a second hand original part..
Edit : Now after reading your post again, you're talking about bits that are actually on the digi itself, not the white caps that I'm talking about! Whoops. I didn't notice any grey spots on the digi itself, but I guess I must have them..

actually it says HTC on it and looks a lil bit differently than on the picture.
never the less, i replaced it really carefully and checked every connecting.
But somehow the Touchscreen doesn't work at all.
Can anyone help me ? what could be the problem ?
Wrong digitzer ?
is it okay, that the digitizer has direct contact to the frame where it is glued to ?

Hi!
I have the same problem, I have asked it already here
So you had invisible finger press in the screen, and the screen was bad responsive?
...Just to make sure my problem is digitizer problem! The service wont change it in warranty unless the problem is there all the time! But its driving me crazy! why is it happening randomly, why isnt it all the time? How could i make the screen to do this problem when i'm at the service?
I replaced my digitizer on my inc and now it will randomly have touches on the screen. I have no idea why this is happening. I have tried two different digitizers with the same problem. It gets worse, i have tried the first digitizer i got on a second phone and this phone has the same problem.
I am running cyanogenmod and have "show touch" turned on so i can tell when its happening and where. The random touches appear to happen all on there own. I can not reproduce them. They do generally happen in about the same spot/spots each time. There are two general areas and when its registers a touch it moves a little, meaning when it touches it self it dances around a little. how ever if i turn off the screen and turn it back on it usually fixes the issue for a while.
Any idea what may be causing this problem and how to fix it?
Funny, I am having the same exact problem. Replaced my digitizer about a month ago and routinely get the "random touches" or just general unresponsiveness while using my phone.
I just assumed it was a side effect of my less then perfect installation but now I wonder if the digitizer itself is shoddy.

Haha, excellent...
Have you considered the trackpad as the possible culprit? I know when my phone does similar things (swiping homescreens, moving the cursor when typing, etc) it's usually because the trackpad is dirty. I can't really think of why the digitizer (assuming it was properly replaced) would be causing that problem..
My buddy Bob had this happen to his Incredible too when he cracked his screen and had it replaced. He had it replaced 3x through Best Buy because each time it came back it would freak out like that. It turns out that something inside the phone was shorting out to the chassis, it would only happen when he squeezed/held the side of the phone. They ended up just giving him a new one after the third time.

Yeah im thinking it could be something shorting but no real way to test. But after many take apart's i seem to have got the screen to a point where it does it like all the time rendering the phone useless. i have put back on the original screen and am seeing if there are problems there. (i got a new plastic housing)

Yeah i have disconnected the track pad and tried that with no change. and i tried disconnecting the light bar for a try and it would not boot. but i only tried once and i could have messed something else up when i put it back together.
i will report back with how the stock screen does and i'm thinking that will confirm that its the replacement digitizers .
Well the stock digitizer is doing the same thing. So its someting on the board, but i have tried it on two different phones.
So im up for trying just about any suggestion at this point. I have 2 phone and 3 digitizes doing this.
Mine does the same thing. I replaced just the screen awhile back.
I thought it might be related to maybe an upgraded screen family and the kernel not supporting it or something..
Like this post:
http://forum.xda-developers.com/showpost.php?p=15132827&postcount=3626
I usually take off the back and then pull the battery and snap the case back on. Seems to fix the problem until I mess with the battery again.
Anyone know how to see what touchscreen version you have?
ok so i have 3 phones(boards) 3 digitizers. 2 phones are the same hardware version i believe, one isn't. and all three experience this problem. This is even with swapping around the digitizers. I'm thinking that somehow all of these share something similar. All i can think of is me putting them together.
Any idea on what they share?
Just wondering if you ever fixed the problem or got it figured out to some extent?
Same thing is happening on my phone ever since I replaced the screen/digitizer. Took it back apart and cleaned all the ribbon connections and the problem is still there. Thinking it might be a grounding issue possibly since it seems like it goes away (most the time) after I vigorously squeeze the bottom of the phone, by the trackpad and capacitive buttons. But it invariably comes back, and seems to be worse when plugged in to the charger for whatever reason.
Also, since you've also taken apart and reassembled your phone, have you had an issue with the trackpad not sitting flush with the screen? No matter how I reassemble everything, it seems like my trackpad is recessed now and it's even worse when I use the little rubber gasket that was on there originally...
I haven't been able to determine what the problem is, but mine seems exactly like yours. When charging I pretty much can't use my phone random touches everywhere, or it doesn't fully reconize my touch. I just took my INC all the way apart and cleaned everything connections and all. I read somewhere it could be a dirty optical pad so cleaned that good too. Just powered on *Fingers Crossed*

I haven't been able to determine what the problem is, but mine seems exactly like yours. When charging I pretty much can't use my phone random touches everywhere, or it doesn't fully reconize my touch. I just took my INC all the way apart and cleaned everything connections and all.

when you replaced it did you make sure you the ground straps where connected to the screw holes with nothing interfering? i pulled my LCD out of my screen on my dev phone because there was dust under the glass. after i put it all back together i was getting the same thing descried in the OP. so i took it apart and noticed that the thread lock used on the screws pealed off and on the ground straps. so i cleaned them up with Alcohol and a cotton swab. put it back together and haven't had it happen sense.

When you say ground straps, are you referring to the two tiny screws that are near the top of the actual screen (after you've taken of the red battery compartment thing and the board)? I remember there being these little metal mesh strips that were in those screw holes that I think I promptly lost after taking the screws out..

yes. after removing the board on the back of the LCD screen there are 2 straps on the top that ground the screen to the frame. the screws had blue thread lock on the bottom. sometimes it will come off when you remove them.
basically make the head of the screw is clean and the metal straps are clean to make a good enough ground.
EDIT:
if you lost the screws you can try to pick up an eye glass repair kit. the ones used for glasses. they have small phillip screws that might work. you can normally buy the kit at a $.99 store.
I was wondering what the screws were for since it didn't look like they were actually holding anything in.. I didn't lose the screws, just the grounding material, which were those metal mesh adhesive strips. Trying to think of what I may be able to replace that with, maybe just some aluminum foil or something? There has to be some better material, I'm just not thinking of it..

the straps fell off? (the straps are on the back and should be soldered to the drivers on the rear of the screen) i wouldn't recommend aluminum foil. try going to a store like radio shack or any do it your self electronic store and see if the can sell you some fine wire mesh.
Hm, I think we must be thinking of different things, cause these were just tiny little pieces of wires mesh that those screws held into place that were stuck to the metal on the back of the screen. Might have to open it up again and snap a picture or two to clarify if I can't find any other grounding issues, etc.

yea thats what im talking about. the 2 straps on top that are screwed in. they need to have a clean connection from the strap to the screw heads that it sits on after screwing them down.
Well I'll be damned, I think that was it! I "borrowed" a little bit of that wire mesh stuff from the back of the screen (it's holding down the screen's ribbon connector and covering other things) and put the screws back in holding little strips of the mesh down and stuck to the metal on the back of the screen. I haven't been using my phone much but the phantom touches and vibration haven't come back, crossing my fingers that it stays this way!
Thanks again synisterwolf, mashed your thanks button a bit
To the OP: I'd highly recommend making sure the screen is grounded properly with those two tiny screws towards the top of the screen.
Thanks for the info guys! Does anyone have a pic of this mesh stuff. I think my old screen had it, but the new screen does not..

you are welcome. glad i could help and glad i took mine apart. now i can see how it all works. it was hard with my big hands but it was fun.
I recently bought a galaxy s3 off ebay that just needed a glass screen repair. Having done several of these with other models I thought no biggie ill ju st change out the digitizer and have a heck of a deal lol until I started looking into how the phone was made and the screens being fused together like they are. I followed a youtube video and heated the screen with a hairdryer and proceeded to try and carefully tried to remove the outer glass without harming the digitizer or lcd screens fused behind it. Unfortunately when I removed the glass screen the digitizer came with it. I thought id ripped the digitizer's flex cable til I read this phones digitizer doesnt connect that way. It didnt crack the lcd screen in any way tho, so Im pretty sure I can just clean the lcd rly well and make sure all the adhesive and glass is cleaned off and use new 3m adhesive to install a new digitizer then the glass screen over it.
The only thing im questionable about is a thin brown ribbon/wire that was pulled out of its original place iand tore a little while doimg this removal. Some of the adhesive from the factory apparently stuck to it while I was heating the glass and attatched itself to the digitizer somewhat or enough to work its way out and initially tear as I was pulling the glass off. Its not the buttons or the small cable that attatches them but it is right beside them. Can anyone with some experience working on these galaxy 3s please tell me what this hooks up, controls, or what other replacement part I would have to buy that would have this ribbon included in it? Or with this ribbon being the way it is, am I going to have to buy the lcd,digitizer, &glass screen replacement that comes preassembled? I know its not the lcd flex cable amd doesnt go to the digitizer so im at a loss.
Im attatching pics so u will know what im referring to. Thanks for any help its greatly appreciated.
Pics after screen removal.
That's why I paid more and got the LCD+Digitizer. Cost more but made it a million times faster.
Sent from my Freeza MD4 Stock Rooted Galaxy S3
Yeah i understand i was just tryin to save a few. I can still do that and not lose but 10 bucks so notjhing hurt if i cant find a solution to this or just make double certain that ribbon being the way it is in the pic isnt going to hurt anything.

I'd go check out this thread and ask some of these guys. A lot of them seem to have attempted repairs already, and many of them have had to troubleshoot different issues. http://forum.xda-developers.com/showthread.php?t=1890708&page=78
