Raplacing the digitizer

Ok so i have a cracked digitizer...
I am going to replace it myself, however this phone is obviously not a straight forward repair.
Anyone have any personal experience replacing the digitizer on this phone? I have seen the youtube videos and read the xda.cn chinese breakdown, just looking for some personal input on the process if someone has one.
Also what will i need to rebuilt it? Do i need double sided tape etc. Thanks

80 views and no ones ever had experience with this?

i replaced it on 2 hd7 phones.
its a real pain to get it off because the glue tape they use goes all the way around, and its strong stuff.
you need to take apart the entire phone to get to the ribbon cable where the digitizer plugs in, so just look for some youtube videos of a tear down and watch carefully.
honestly the hardest part for me was getting the screen and digitizer clean of fingerprints and tiny broken glass pieces without messing up the screen, while keeping the double sided tape i put on in place and intact.
just take your time and everything will go smoothly.
-edit- yes you will need some double sided tape because when you take the digitizer off the sticky layer of the tape goes with it, the rest of the tape stays on the screen and is impossible to get off without damaging your screen so you have to apply new tape over it.
i used some thin scotch brand double sided tape and i cut it into long narrow strips with a razor using my old digitizer as a cutting board, the same width as the original tape.

Hi mate appreciate the advice in my thread on the HD7 replacement.
I managed to get the digitizer out, however on replacing the new one i have a problem..
You know the old digitizer has three plastic prongs, on the buttons at the bottom, search etc.
Am i rigth in saying they need to be transferred to the new digitizer? As i can't see how they fit on the LCD when stuck to the digitizer? It raises the digitizer a little, unless they hand off the edge of the lcd?
Thanks

Those are nothing more than spacers. I have replaced two digitizers without them. As long as you get some good 3M double sided in that area there is no problems.

um no they arent spacers...they are what directs the light to the 3 bottom keys. they are there for a reason so i recommend using them... ... now you are spot on with the 3m tape as it is the tape needed to do this whole job properly... the scotch crap is not made for this and WILL NOT HOLD UP NOR SEAL PROPERLY>>>
and for the person who said to put the tape over the old.... not a good idea... it can be removed and new should be used to replace the old..
sorry but i do this daily for a living so i do have a clue about this... just trying to help make it a successful repair and not one that ends up in my shop after the home repair failed and it damaged more than just the screen.....

Screen lifting

Hi hope someone can offer some advice, I have replaced the screen on my Z3 compact. Screen works fine but it is lifting and not sticking. I have tried different types of tape, I have applied tape to the edge of the screen itself and the frame it's still lifting. Please can someone offer some advice

Any one got any advice, this must be an issue somewhere.

Consider buying a B-7000 glue, it is used for displays mostly, I was advised by a friend to use it, since my screen has unglued as well, and he has already repaired couple of Z3/Z3c devices with it, and there were no reported lifted screens since than. For the back panel, you can use double sided tape, but adding B-7000 glue on one side (to avoid cracking sounds, depending on the used tape probably). You can do a bit of searching on Youtube for repair videos, I recall watching some with the mentioned B-7000 glue, easy to find.
I haven't done it myself, but I will very soon, dust has filled my front cam, and proximity sensor.
Good luck.

I think B7000 will get the job done. I have used it for my device and it has been a month already, screen and back plate haven't moved a bit, its like new. One thing to remember though, you have to make sure the whole frame is COMPLETELY covered with glue, otherwise it will not be enough to hold the screen. I made a mess at first try, because I missed some spots and the screen lifted on sides, next time though, I've checked 3 times for any empty spots and applied glue to those spots, now everything is perfect. Of course, you should cover frame only, avoid applying that much so that glue is dripping inside the phone itself.
Good luck

Gooood,ill give it a shot. But i was thinking if must remove back cover and the screen for glue only a corner...the back cover doesnt have any problem, only the display in left corner is unglued. And if i must to remove thats, i must buy and that adezive black or simple use only b7000 ? Thanks

I have some of the B-7000. Stuck the screen down over a week ago appears to be fine. The only issue I have is that I think the glue has squeezed onto the front camera, the camera is now blurred. I don't use the front one so it's not a big problem.

I have used the glue, it's fine, you don't need stickers
You can try applying the glue only in that corner as well, but I'm not sure how well will that fix the issue.
I had to remove the screen anyway to clean the notification led cutout and front camera, so I didn't care for the back plate sticker.

Back glass unsticking

I have had this phone for about 1.5 years now and it held up,it was running very well but it always had an overheating problem,you have probably seen me all over the forums asking how can I lower the temperature of the phone lol.
Well it has become less apparent with the latest build of Lineage,only when I am using Snapchat but that doesn't matter.
But now what started happening is my back glass is unsticking,the bottom part to be exact,I believe this is because the device heated up so much it weakened the adhesive.
So I am asking now with what material I can re-stick the back glass properly since I don't want it to hang like that for no reason.

Use fevibond
You can use fevibond(Synthetic Rubber Base Glue). I used it to stick front screen peeling off from top left corner.

Could I use something like superglue or something similar to that?

No, that would make it tough/impossible to separate it for repairs.

Nope I wouldn't do that, as super glue is not flexible. I have glued both screen and back glass with B7000 adhesive (most repair shops use it specifically for displays) and it hasn't moved since. That was done some 4 months ago. If you put enough glue on the frame (be careful not to leave empty spots, cover the complete frame with glue), of course avoid dripping of the sides into the frame, I am sure that it won't peel off again, especially the back glass.
I am waiting for new screen to arrive, so I'll have to re-do everything again, of course with B7000.

Never use superglue, it will not last long and will ruin your phone, as superglue's main ingredient disintegrates plastic...
I've also used red 3m tape, does not hold!
Bought B7000 glue, will use it once my new battery arrives, so using useless 3m red tape in the mean time...
-Update-
B7000 Glue works!!!
I heavily flash, test etc. and no matter how hot the phone gets, it's sealed and does not reopen.
I cleaned the surfaces, I applied the glue, and did not care about making a mess (the glue is easily removable for future repairs) and did not care about it oozing out either, just made sure that it covered that border.
I did not use any heat, and it was still cold here.
I then used clothes pegs, 3 on each edge (I was worried about too much pressure, but it was not an issue)
I did not turn my phone on at all, and waited for 48 hours, before removing the pegs then turning it on.
Please note: the z3c is bendable, especially in jeans pockets, I use an anodized bumper to keep it straight. And using tempered glass on both sides is recommended.
***I did however buy a new battery, as my previous battery seemed fat, and I also removed the nfc sticker, but not sure if that is necessary.

Broken front glass (& usb port) - replacement?

Hi guys,
has anyone of you tried changing the front glass without digitizer and display?
In disassembly videos I can only see people changing the whole thing.
Also, do you think I can manage to repair the front glas as well as the USB port with just an iron instead of a hot air blower (and the usual tools made of plastic)?
Thanks in advance!

I haven't done the front glass on mine yet, but my understanding is that in general you're really better off replacing front glass as an entire unit with digitizer and display. An iron on pretty low through a cloth/towel might well work. It's not just glue that melts, it's a thin strip of rubber gasket material with adhesive (okay, maybe it's thick glue, but it looked pre-formed to me) holding the glass back cover on.
Heating probably helps a bit with softening the stuff, but after the first time you peel it up you won't really need to do that again. I'd recommend picking a corner (say, bottom left as you're looking at the back) and just plan on prying from there every time, so you only have one spot where the plastic gets marred.
Don't spend too much time heating, worry more about having a suction cup tool that you can lift with while you try to work a guitar pick or hobby knife or something in under the corner. Have at least two ready, so you can wedge one in, and work your way around without it just dropping back down on you. You'll probably tear the material a bit but that's okay, just spread it back out evenly around the edge on the glass before you put the cover back on. Also, you definitely should be using a case to make sure it doesn't just fall off in your pocket once you've opened it up a couple times.
USB cable replacement isn't awful, just time consuming. The biggest gotcha is to keep all three of the little gold clips on the plastic "mid frame" ring (that's the first thing you remove that requires screws after getting the back glass up) from fallling and getting lost.
You can PM me if you have any questions about this, I've replaced my USB cable/port assembly a couple times (first replacement was defective). And I'm about to attempt replacing the screen as a whole unit with glass & digitizer on my wife's Z2 Plus, so I'll let you know how that goes.

Display Replacement

Hey guys,
unluckily my Display (not the glass) got broken so I have to replace it and also ordered it already. After watching a few teardowns I have two questions:
Do I have to remove the back or can I just warm up the adhesive and take the screen off?
Can I use glue to replace it or do I have to use tape and can I use normal nail polish remover to remove the adhesive residue?
Sincerely

You can go through the front, but it definitely would be more risky since all components will still be connected.
I would personally not use glue. Glue is meant to support more rigid materials and the components in the phone are quite fragile. Though you could use very thin electronic glue. Not sure how well that would work.
Regarding the nail polish remover, I would not use that unless the content of water is <10%. You want at least 90% alcohol content for cleaning the adhesive. Your best bet is IPA (isopropyl alcohol). It will clean better and will not risk water damage to any components inside the phone.

So you say I have to do it from the back?
What is the risky part of going through the front?
Because of glue: Can I use any double sided tape I want?

So now I opened the ROG Phone 2 through the back and made the following experiences. And for all those who are wondering the same:
In my opinion you can't go through the front because the display is connected with a flex cable through the middle frame (which is indepentend from the display so the display comes without a middle frame where the components are assembled in like in many other smartphones) to the motherboard. Though there is a cut out in the middle frame for it but the motherboard blocks it so far that only the cable itself can go through and not the connecting port. Maybe you can disconnect the display but not connect the new one without disassembling the motherboard from the middle frame. And that's only possible with going through the back and loose the screws. In additon, especially after a fall, there can be more components be broken as just the display. In this case you can connect the new display and check all the functions before glue it together back again.
Because of the glue:
There is a glue available in two colors called B-7000 and T-7000. One of them is black and the other one is transparent depending on the color of your smartphone. These glues are especially made for smartphones. If you watch the Display replacement videos for the ROG Phone 2 you can see that they are using this type of glue and not double sided tape since it has to be 1 mm or narrower to be able to glue the display with the middle frame again.
For the back you can use double sided tape.
