[Replacing Digitizer] Is 2mm 3M double-sided tape a must?

I have in front of me a perfectly fine HTC HD2, but the digitizer is cracked and not responding.
I ordered a TMOUS HD2 digitizer replacement, and am waiting for my T5 torx screw to come.
Beside these things, I heard that I'll also need 2mm 3M double-sided tape.
Is it possible to reuse the ones that are currently holding the cracked digitizer?
Or should I start hunting for some of those tape?

I used 4 drops of superglue when I replaced mine...

I used crazy glue but it left white residue. I cracked digitizer again so this time I will use 2mm tape, not crazy glue. I also used regular 3M tapes 1/2" wide but I had to trim it. It's a pain in the ass but doable. Now, I will buy 2mm tape instead.

Has someone a link?
Today i reopened my phone because using the old pieces of tape wasnt holding enough, so the screen was a bit over the housing.
Now i used thin tape (noname) and had to cut it myself, what really is a pain in the ass. THe problem is, that with cutting and then fingering this togehter my screen not is very stable but still to high.
If i order tape now i want to buy the right one!!!
Has someone a link or article number? Dont want to buy just a 3m 2mm tape that is to thik or something...
So 1mm or 2mm?
Is there a difference in hight?

I got this:

Thank you!
What did you use it for? Only the display and touchscreen or did you glue the display to the housing and the part unter the buttons with this too?
After opening it twice i think i need:
-Display with touchscreen
-Display in housing
-The parts of the touchscreen that stands over the display ( buttons and lightsensor) , to the housing..
Do you know a more exactly name for the Tape?
Someone wort about LSE300 but this is only the category name ;D
But anyways thank you for the seller, the tape was good for yoU?

How did you guys remove/plan to remove the glass from the LCD?

Just warm it and with a razor(razer? you know the sharp flat knives ;D) you cut along the edges.
Just make sure you move the razor parallel between the touchscreen and display, so you dont break or scratch the screen.
For heating up, you can take a hair dryer or put it in the oven for 5-10min. I think 50°C(a bit longer to heat all trough) . More temperature shouldnt be a problem, sun on black surfaces often gets ~80°C but dont risk it, and you need to touch it to remove the screen
------
For the soldering version a little hint:
The cable on the new touchscreen can be soldered from top and downside.
You dont need to solder on top the little overhang, just put a bit soldering tin between, then cable on top and let the heat go trough the cable to heat the tin on the underside=> more space and all the way conected.
There is a little round mark to alighn the new cable. Use this, or the chip on the cable will not fit unter the hole in the housing ;D
If its hard to solder just put a bit soldering tin on the display first. Then put the cable above and press the soldering iron on top. The soldering tin you put between will connect them perfectly. Use a tool to press the cable on the display untill the soldering tin is hard.
The secret of basic soldering skills is not to move after you take away the soldering iron until the tin is hard, every movement in these seconds makes the soldering spot weak or its not connected right.

Wow that's quite interesting. I broke another hd2 a while ago, and its just laying around. Screen works well, I just hated the cracks. I may try this out...
Edit : if someone could make a video tutorial, that would be sweet. The one online isn't so great

I haven't used it yet, because I bought it last week and they're still shipping it to me.
I'm going to be using it to replace the tape between the old digitizer and the LCD.
I thought the display-to-housing tape was padded, wasn't it?

Yes, there are many kinds of different tapes. Thin, padded, metalic and some seemed to be more like glue dots.
But i dont think its so important do rebuild this exactly
Starting from 5:00 he seperates Display and Touchscreen ;D
But the guy soldered from top, you can actually see it at 7:40, i think its better to solder between display and cable, as i tried to describe above..
That lucky guy was able to reuse the whole tape as it was, but im not sure if it is still so good, even if it is one piece.
When my tape comes, i will eventually make a little screen replacement video ;D
But my camera is not very good at close-ups, but i try ;D

HD2 fixing advice, regarding glue

So I replaced the cracked digitizer on my HD2, and it was the most exhaustive repair ive ever been through in my entire life. However after I have replaced the digitizer and taken the phone apart a few times to properly seat things back together, the digitizer gets dust underneath it because the seal is not perfect.
In the disassemble directions you had to heat the phone up to 140 degrees for 5 minutes in order to sort of melt the glue that held the pieces together nice and tight, it was a black double sided gooey substance.
Since separation, some of that was lost and i'm looking for something similar to replicate it to create a proper seal for my hardware all around. Anyone have any ideas on what I can use? And unless you're dead serious, don't say gorilla glue, because I may need to service it again in the future.
Thanks!

How about a cheap hot glue gun?
Sent from my HTC HD2 using XDA App

Its an idea except i dont want the hot glue to expand too much when pressure is applied, and also its not something that will allow me to get back into it with heat at 140 degrees any other suggestions?

I'm thinking that a couple tiny dots of silicone will work. It's non-conductive, flexible and not permanent. I'm getting good at tearing these apart, but like you they don't hold together once you wreck the glue.
One thing I did do was heat it up and press it AFTER the repair was done. I reheated it for 5 minutes with the hair dryer (I use a music stand to hold it so I can go get another beer - but 2 beers is my limit with these tiny parts).
I'm also going to try 3 layers of double-sided tape too, which is similar to what is in other phones. Or that stuff from the back of credit cards. Oh, that's probably rubber cement. I'll try that too
As you can see I'm still working it out too.

Repair HD2, now trouble assembling?

I recently tried repairing a friends HD2, because he had a smashed screen.
I bought the new screen and some 2mm double sided tape. Took the phone apart, and managed to see the lcd was damaged also. Bought one of those then taped the new screen and lcd together using the tape.
The inner chassis had all the old tape on it still, so I bought a new inner chassis. Waited for it, then stuck the new lcd / digitizer to it. The button end didnt seem to stick down that well - even with the new chassis, with the buttons wanting to drop out, and them not sitting out of the screen like they should.
I thought it must be due to the phone only partially assembled, so went ahead and installed the rest of the phone.
Now its together the button end of the phone wont sit in the shell properly and the buttons seem to be lower than they should...
How am i supposed to get this inner chassis to stick properly, and are there any tips or vids to show how its supposed to sit?
thanks.

maybe this video can help you with assembling your phone.
Search on youtube for t8Q7mXdcJ54.

Ive watched that video numerous times, and its a little misleading as to how much is required. Extra tape in places that had to be cut and removed, labels not sticking back down like they do in the video etc.
Im after information as to how people stuck the lcd/digitizer to the inner chassis. I used a new inner chassis with tape pre applied, and it still didnt seem to stick the two things together enough. When you stick the chassis (with lcd/digitizer) into the outer case, it doesnt sit into the case enough, and the buttons are not sitting right.

If u have purchased lcd with digitizer,u could look for flat cable that connects from lcd to mbo,maybe u need to form it.buttons have points to allign,but u need to center both sides in micrometer to function normal.lcd/digitizer frame must have black tape on edges.

done this and still no luck

I have the same problem like foney!
See this:
argh, i can't post my photos! how to do it now, i don't have 8 posts yet!
I've used "3M 300LSE" as a profesional doublesided tape i thought and also put a 2mm stripe below the keyboard, but the display is not really fixed onto the chassi around the keyboard and the keys also can't be used really, because they are maybe not correct centered onto the keyboard circuit board. i've been using the assembly video from htc, but there it's not mentionend very well, how to do it right.

Hmm,last thing i can think is that lcd/digitizer is not properly glued/taped.Did u put pressure for few hours on lcd/digitizer and middle frame?

it is taped on around the lcd using 2mm 3M double sided tape. The chassis i bought new, with tape included. When you stick the lcd/digi to the chassis, it appears that the button end, as l0rdius mentioned, isnt stuck down enough.
The video has the guy "magically" sticking it all together and all going together as it should, but doesnt show any real detail, like showing how things go together to fit properly.
edit/ pulled the phone apart again, and its definitely a case of the tape on the chassis near the buttons not sticking correctly. Ive wrapped it in rubber bands, and used some wooden clothes pegs to try to secure the two better. If it doesnt stick, then I may have to use something stronger than tape, like Tarzans Grip

I've found another thread, in which "profahmad" posted some hints:
http://forum.xda-developers.com/showthread.php?t=640328&page=8
Today i've ordered some more 3M 300LSE and want to take a new try on weekend with these hints. Hope i get the display better glued to the chassis and the buttons correctly justified.
Whats about the sticker under the battery. do you guys have problems reassembling it again and again? Or how do you handle it?

Im using glue like in the link if applying pressure for a day or two doesnt work.
I applied a little double sided tape under it, then when i left the phone for a few days with the battery in it seemed to stick down fairly well. Not like factory new, but good enough.

[Q] Replacing glass - to LOCA or not

I picked up a cracked glass/working LCD S4 for $100. I've ordered replacement glass and watched several videos of the process and I've done this kind of thing before (careful delicate work with electronics that is.) Phone works fine, just the glass is cracked - but touch, lcd and all features seem ok.
The only aspect I'm unsure of is whether I really need to re-glue the new glass using something like this: LCD Glue
It sounds like a lot of people have just done the glass, no new glue and heated the phone slightly afterwards to re-adhere the tape. I'd rather not use new glue if I don't have to - looks like a messy step and one that could easily go wrong with too much glue and I don't have a UV curing light so that'd add to my cost of doing this.
Does anyone have firsthand experience with a phone whose glass has been successfully replaced either with or without new glue?
Thanks!

Loca is about the closest your gonna get to a oem experience, but if I was you, I would pay Samsung to fix the display.

I've completed the operation without adhesive and it was largely a success but there's a small bubble spot on the display. I like it better than the cracked glass but it's not perfect. I've got an S4 for slightly over $100 - even if I just have an S4 with a spot for $115, I can live with that. And I may redo it and use adhesive. I just got it because it was cheap - I have a Note 2 I'm still quite happy with and don't intend to switch over. If I pay Samsung for anything, it'll be a Note 3.
Considering how I felt part way through getting the glass off - I was fairly sure I'd destroyed it - I'm very happy with the result.
Thanks for the reply!

That's great glad you had some success!

This is from my personal experience with replacing glass on my S3.
1) replaced JUST the outer glass and all was well with how the phone worked. With just replacing the glass there were a couple cons to it. First con was it was VERY HARD/almost impossible to see anything on the screen when out in the sun. Second con was that you would either have what looked like a bubble under the glass. This was caused because the glass was touching part of the lcd and would look like it was wet in the middle of the phone. When you press on the screen the WET LOOK got worse. But heck for the $20 I spent on the new outer glass I had a functioning phone. Third the outer screen is now not sealed and you can get dust/debris/liquid in between the glass and lcd which in time will look bad.
Now onto the SECOND TIME I broke my glass on my S3. I used LOCA that cured using Uva light. Well it looked great but I did not have a Uva lamp with me at the time when I did it and the sunlight didn't cure it fast enough. So the phone LOOKED and WORKED perfectly like it was brand new for a few days . Then my lcd stopped working. Pulled phone completely apart and found that the uncured LOCA had made it in between the lcd and the electronics part if the phone and shorted it out. So this is where I went wrong and LEARNED from it.
LOCA is great and I would recommend it with these instructions. 1. Before applying LOCA remove EVERYTHING from the phone. And I mean everything. So you only have the front glass, lcd, frame/bezel. This is very easy to do and only held together with 10 or so screws. Then use LOCA and MAKE SURE to have a UVA LAMP on hand before attempting. Once it is full cured with the lamp (only takes a few minutes under the Uva lamp to fully cure) then you can reassemble the phone and it will be like brand new. Still for only about the price of $50 for the outer glass and LOCA.
Read in the ATT S3 forums and you can learn a lot before attempting it. You will see where things can go wrong and where things go right. I was one of the first guinea pigs to test out the LOCA and after making my mistakes other learned and we're able to complete it correctly.
When my lcd went out I just bought the S4. Finally I recently bought a lcd with a cracked outer glass, new outer glass, and already had some local still. Now my S3 looks brand new again and functions perfectly.

LOCA, 2mm double sided tape and a UV Light on the way. Even with all that my cost on the phone isn't bad. And I can cure nail polish too!
I do plan to remove as much as I can from the phone to prevent the glue shorting anything.

Well the patient lived but he isn't entirely his out of the box brand new self...
I did remove the mid-frame and motherboard and I'm glad I did because if I hadn't, I'd have had adhesive in between the mid-frame and display assembly I suspect. I didn't use enough adhesive at first so before curing it, I pulled the glass back off and put more adhesive in. When I did this, it introduced a few bubbles and worst of all, some adhesive got up where it's barely obstructing the front facing camera. It still notices when you wave your hands at it and I haven't played with it a lot yet.
I didn't fully understand how LOCA cures - you can hit it with UV for a few seconds and it sort of "pre-cures" and then wipe away excess and whatnot. I didn't do that, put the UV on and left it curing the excess and gluing the phone to the bench with adhesive than ran out lol. A bit of scraping and clipping later I got it unstuck and cleaned up but had I just pre-cured, wiped up, then long cured it'd have been better.
Not unhappy considering it had broken glass, now it doesn't and it looks decent and is functional and I don't have much $ in it for having an S4 to play with!
Update: I took the phone apart again and removed the front facing camera and did a little cleanup with acetone & some q-tips. Front facing camera is now fine. Only diff between this phone & stock/new is there are several bubbles - but several bubbles is a hell of a lot better than broken glass! Touch is very responsive and contrast looks great.

Something else to watch for......
On larger phones, like Note etc. LOCA glue is NOT an option! If you don't use it,you will almost certainly have problems with the touch sensor. Part of the glass will touch the sensor, usually near the middle of the screen. This will cause all kinds of random behavior and can even cause the phone to appear to lock up or freeze.

Samsung Galaxy S3 I9300 - Extra Screen Replacement Information

My Ex droped her Phone and it had Spider Webs all accross. Her Provider send it in to see what it would cost to fix. The Phone also would stop working correctly in the middle of calls.
It turns out buying a new one would have come cheaper atleast thats what came back as a answear.
So I decided to bite the apple and try replacing the Screen myself. My Ex was not happy because she thought with the second Problem it is not worth the effort to fix the Screen and maybe loose everything. My reasoning was that when the Spider Web Screen touches the Digitizer it will react strangely. So I went ahead and searched the web on how to do it. I ordered a Screen for $9 on ebay (free shipping) which came with a couple of Tools. More on those later.
One of the first Problems I found was that all instructions that I found showed the beginning and the end. But in the middle how the phone will look like when the glass is finaly taken off, I was unable to find much Information about it. Also doing it Redneck style without Special liquids and or a heat guns was no where to be found.
I decided to just try it. Disasembly is well documented and easy enough to do on this device. Atleast to the Point where most electronics are removed so that you can apply heat without too much problems. I decided on using a blow dryer to heat up the Display. I layed the Blow Dryer on the Counter turned it on and Held the phone up to it. Thinking if my fingers get too hot chances are it is too hot for the Display too.. Might be a little incaccurate to read the temperature like that but hey it worked. But soon after I started to remove the first pieces of broken glass I ran into Problems.
As per instructions I found, I put a Piece of tape accros the Screen so that the individuall pieces stayed ogether. That did not work at all for me. It just made the individual pieces push against the valuable digitizer below it. My next Problem was that the Tools that came with the replacement glass, especially the Little plastic Tools did not hold up to the Job und the tip was soon useless. I had to Switch to a Raizor blade. A couple of times I sliped and hit the Digitizer. Thinking oh well I guess I Need to get a new one. Luckely on the end it all worked out much better then I would have hoped. The left over glue I rubbed mostly off with my finger which worked out nicely. To clean it completely from ist glue took some time. The black rubber allong the side of the phone allso suffered. You might want to look out that that does not get riped out completely. I had enough left over so that the glass would sit on it good enough luckely.
Take a look at these Pictures and remember it works perfectly again for $9. While it is not for everyone to seperate a Glass from a Digitizer it is acctualy less fragile as you might think. The third Picture Shows you how it looked with all the scuff marks from taking off the glass. You can still see a few little marks on the end but hard to notice and much better then before. I am sure next time I will be more carefull and use the blade from the beginning on.
I got more Pictures and will improve this Thread for others that have to go through it. Feel free to PM me if you have any Questions. A list of other resources will also be included. This is only to explain and Show the bare state.

You should be able to find a new Frame for a resonable Price. Now to remove the digitizer from the Frame that is another Story. Not sure if it was the Glue or what Held it in place but I could not figure out how to get that out. luckely the two Buttons at the bottom survived the Screen removal and so I did not hat to take the Digitizer out.

Useful information and explains why repair shops will usually only replace the complete assembly. Read many complaints that those cheap ebay screens are plastic and easily scratched, not genuine gorilla glass replacements?

It is definetly cheaper then the original but if you have done it once. Chances are You will be able to do it again much easier. So if the $9 Glass only holds for example a Year. You can just replace it again. Or spend a little more for a original replacement glass.
Now I should Point out if the rubber seal around it gets damaged in the process and if the 3M Tape that should come with the Screen is placed wrong it will Impact the sensitivity of the sreen touches. I guess I did it right because my Ex is happy how it performs and that is saying allot.
