OK so here is my setup..

First tape the crap out of the digitizer with packaging tape, that will hold the small shards of glass in place as you run the wire between the digitizer and the LCD.

Second heat at ovens min temp for 20 Min:

Here is my setup, 2 pieces of wood that I use as a base to hold it in place while I work, and 2 block with holes drilled in them to connect the cutting wires to:

This is just after the digitizer has ben removed from the LCD

Here is my setup for removing the glue on the LCD, I use the glue remover from the lcdglue website, and plastic razor blades to scrape. Also a tooth brush to spread the glue remover on the lcd.

This is mid removal of the glue:

I don't know if this helps anyone but I hope so. I recently had my Nexus dropped and, yes the screen broke. The digitizer was broke too...no more touchsreen. I thought it was all over. Anyway I had an idea...I had an OTG cable (on the go cable), so I plugged it in and attached a mouse. Hey Presto! I had access. The mouse works like a dream and I have access to everything even though the touchscreen doesn't work. Ok..typing is a tad slow. I'll get the screen fixed but I'm suddenly in not so much of a rush as I have a perfectly working Nexus, albeit with a cracked screen.

I hope this is of some use to someone.

Yup, any USB hid device will work just fine through an otg cable. In fact, you can plug in a USB hub and connect both a mouse and a keyboard (and camera and joystick and...) As long as you don't exceed the otg current spec which I think is around 300mA. Use an externally powered USB hub and go wild!

I have successfully separated the digitizer from the LCD on my Nexus 7 too!! I did not have a hot plate or anything fancy so it took a whole lot of patience. I did use a head gun and a bank card to start, and then continued with stiff cardboard business cards while going towards the middle as I was afraid of cracking the LCD. It did take me ONE FULL DAY to take all the little pieces of broken glass off, but I did it! Its a good thing that I was on vacation as it would not have been worth it spending a full day to take a apart an assembly worth under 100$, but as I got the tablet for 20$ (for a 32gb) I was more curious than anything else if I was going to be able to get it off without destroying the LCD. After the digitizer was off I did put some goo-gone on it, it helped to soften the glue but it would not go off easily, even with a razor blade. What I ended up using was a simple while eraser and it worked great. I tried a few different things (acetone, butane, 99% alcohol, goo-gone, electronic contact cleaner) and nothing would work. Who would have thought than an eraser would have taken this off so easily. :) Hopefully this will help someone who is stuck with this glue like I was :)

(btw please any mistakes I may have made since English is only my 2nd language ;))

[Nexus 7 Q&A, Help & Troubleshooting] graphdarnell:
Am I reading it right that on the Nexus 7 2013, the lcd is glued to the digitizer only around the former's edges, i.e.no OCA on the whole display surface? Can someone confirm this? Thank you all.

I can also confirm that a regular eraser works wonders towards cleaning up the glue residue. A half-hour work removed about 80% of it, provided you applied with a steady hand without too much pressure on the glass. I did not use a very soft eraser, but have the feeling that it'd work even better. Thanks for the tip.
[Nexus 7 Q&A, Help & Troubleshooting] repairsuniverse:
I believe the LCD is fused to the glass as with the first gen. The repair can be done it just takes a lot of time and patience. Just be aware that there is a possibility that you may damage the LCD.
[Nexus 7 Q&A, Help & Troubleshooting] graphdarnell:
Progress Report: I picked up a bag of soft erasers from a dollar store today. Proceeded to "erase" the glue residue on the LCD, and it worked beyond expectations. If you look at the enclosed thumb, the marks you can see on the screen are from fingernails, bamboo toothpicks, and all kinds of soft plastic tools. The eraser, on the other hand, left nothing. No marks whatsoever. Almost foolproof.

I do recommend the soft kind though, to ease pressure on the glass surface, and some patience while rubbing it. It might take 10 or 20 seconds to lift off a sticky blob, but it will eventually. Apply pressure downward just enough to rub the eraser against the surface and no more than that.

Again, thanks to RaisedFist for the tip. This will help other DIYs tremendously.

Hi, I bought a 30 dollar used mother board from eBay just for that reason, I couldn't find it as a spare as well. I'm waiting for the mother board to arrive, so I will have only one of these white lock flaps you want, from the old mobo. I can send it to you, but it's a bit difficult to put it back on and make it stay there even after you lock the flex cable connector with it. Let me know if you want it.

[Nexus 7 Q&A, Help & Troubleshooting] Serenadier:
Need advice here.

I know this might've been covered in this thread already but I need to make sure before I charge hundreds to get a screen & digitizer shipped all the way from China (I live in Asia).

So I broke my Nexus 7 3G (2012) by dropping it - it appears that the digitizer is the only broken component and the underlying LCD is unscathed. What do I do? I've read that the digitizer and screen are impossibly hard to separate, and so I'm considering getting the screen & digitizer combo. But then, my N7 is a 3G version, and the packages up for sale on Aliexpress/eBay, if it comes with a front plate, are for the WiFi models. I want to replace my 3G's front plate but I can't find any.

So how do I separate the screen & digitizer from the front panel of the 3G model? Is it possible to do so without damaging it? And how do I put it back together once I get the new LCD & digitizer?

Please help. Thank you very much for your time.
[Nexus 7 Q&A, Help & Troubleshooting] jptech:
I have the same exact issue. I replaced the OEM hynix screen with one from chungwa. Now it even happens on my old screen. I've ordered a replacement video ribbon cable and will see today if that fixes it.

**UPDATE**

a new LCD cable turned on the backlight, but one half of the screen is all red and the other is garbled

***UPDATE***

fixed it. The LCD cable connection at the lcd panel is exceedingly sensitive. Remove all tape from the cable and reseat it very carefully. Then replace the tape.
[Nexus 7 Q&A, Help & Troubleshooting] Captain Sweatpants:
OK here is the process for separating the digitaliser and LCD please note this is very difficult and there is every possibility of breaking the LCD.

The LCD is fused to the digitaliser with a thermal glue to separate them you will need heat about 80 Celsius.

You will need :

A hot air gun or other source of heat

(the pros use a heat plate that you clamp the screen to. A heat gun will work at a push.)

A length of very thin high strength wire

( pros use gold wire but you can use a violin E string or similar.)

Cleaning fluid.

(Some people have had success using an eraser to clean off the glue. Do not use contact cleaner as it will seep into the LCD and you will have washed out colours for weeks afterwards.)

1: Get the screen secured in a way you can draw the wire between the two components.

2: Heat the glass side until you judge it hot enough to have softened the glue.

3: Draw the wire between the LCD and digitaliser. This may take several attempts of heating and pulling the wire.

4: Once you have completed this very carefully prise the two apart using a PLASTIC tool. Do this while the glue is still hot.

5: Clean off the remaining glue from the LCD taking care not to scratch or damage it.

6: For reattaching the the LCD to a new digitaliser use a narrow double sided tape 3m produce a 2or3 mm tape for this purpose. Do not try and fuse the two like the manufacturers do you will only end up with a mess.

If you only want to remove the bezel then the same idea heat the glue but this time take great care not to melt the plastic and gently prize off the plastic bezel
[Nexus 7 Q&A, Help & Troubleshooting] Serenadier:
Ah, thank you so much for the lengthy post, I sincerely apologise for not realising I didn't follow up to this.

Sitrep - I've did some research on it, and found that it'd be most efficient to replace the screen & digitiser assembly together, since it is bonded to the bezel and much easier done compared to separating the digitiser from the LCD and replacing it.

I've ordered a screen + digitiser assembly and it should arrive in about 2-3 weeks time. Thankfully I've managed to get a Nexus 5 to replace its duties for the time being. Once again, thank you so much for the advice!
[Nexus 7 Q&A, Help & Troubleshooting] graphdarnell:
I have a question for repairsuniverse: (1) if you use 3M 2mm tape around the edge of the lcd to bond it to the digitizer, doesn't that inevitably leave a gap, no matter how minimal, between the two? And (2), does the lcd's front surface absolutely have to touch the back of the digitizer, or would a gap as in (1) suffice to facilitate normal touch operations?

In other words, why would a hollow cause touch lags?

I'm asking you since you seem to repair more than anyone else. Thank you in advance for any response.

Did you ever find a good way to clean the excess glue off the LCD, and how did you attach it to the new digitizer?
[Nexus 7 Q&A, Help & Troubleshooting] Sp_Ark:
If you have a lot of patience you can clean it with a cloth, some heat and any alcohol based liquid. Otherwise you can buy loca glue remover. Then you can put the digitizer without glue. The main purpose of this glue is to keep the lcd and the outer glass clean from dust and moisture. You can buy loca glue as well but you will need a uv lamp to make the glue stable and you have to be extra careful not to leave gaps and bubbles while applying it. The better the quality of the loca glue the clearer and brighter the lcd backlight afterwards. Most service centers never put new glue. Sorry for my English.

[Nexus 7 Q&A, Help & Troubleshooting] Sp_Ark:
Try aliexpress search for lcd assembly. There is a seller that sells ready ones with a frame for the wifi version and at very reasonable price. Although the frames he uses are used so they might have bents and scratches. The lcds and digitizers are in great condition. Probably he is refurbishing used but originals lcds with frame and gluing brand new digitizers.

Touch screen functionality issues

Hi guys, I need some advice on an issue I have with a replaced touch screen. When I recently bought some new touch screen assemblies for my boys' Nexus 7s, I accidentally bought the LCD only. Fortunately, I still had a touch screen that I bought ages ago when the Nexus broke the first time and I learned the hard way that the LCD and screen are fused. So I went ahead and replaced the two separately. However, whilst the new LCD works beautifully, the touch screen sometimes stopped responding after a few minutes and you had to turn the screen off/on to get it to work again. It also had the problem on not recognising the touch-hold function in many apps despite working fine on the home screen when moving around app icons. I thought I had a dodgy screen and since I bought it over a year ago, couldn't do anything about it and bought a new one....

...but when I installed the new screen, it still has the same issue with the touch-hold function in many games which frustrates the hell out my son and limits his Nexus to only a few games that work fine. I thought the recent Android 5.0 update might help, but it doesn't. Has anybody any ideas why this is happening? Does the digitizer need to be glued to the LCD to work properly? Or do I have a different kind of problem? Any advice would be much appreciate!!!
[Nexus 7 Q&A, Help & Troubleshooting] ovu85:
Hi, i've bought a nexus 7 replacement lcd+touch from this seller http://www.dhgate.com/product/oem-n...r/172660883.html#myaccount_orderdetail-1-null then the screen arrived it was a faulty one. The lcd was genuine but the touch is ordinary. No gorilla glass and it had so many dead zones, practically impossible to use. I though that the connectors from the motherboard were broken but realised that the ribbon connectors were not the same, visibly bigger.

So i shipped the screen back, spent 20$ for shipping and waited about 1,5 month.

The second one arrived and was better but still the touch is not so responsive as original one.

My advise is, spend a little more and buy a genuine one!

LCD screen replacement issues.

I have a 32GB WiFi only 2012 nexus 7 with a cracked screen. I have replaced the screen (LCD+digitizer) following some guides I found on you tube but the new screen is still not working ( all I get is a black screen) . I can hear the chips of my nexus when I plug it in to charge so I know the battery and mother board must be working. This is the second screen I have attempted the repair with and both have just been black after the repair.

I got my ribbon cable from edens_designs for $4.65 US via ebay (see http://www.ebay.com/itm/400548678981). They are "no frills" and ship from inside the USA.

Replacing LCD and digitiser separately

I have accidentally bought 2 LCD's instead of the assembly, so I thought I replace them separately. I posted about issues with that on previous page on this thread. I have now done this again on my other son's Nexus and the bloody digitiser is not working at all. I am beginning to wonder whether they are not meant to be separate, although earlier in this thread people claim it works. Has anybody else done this? Am I just incredibly unlucky with my replacement digitisers from AliExpress??? I would be most appreciative of any comments. I am close to giving up and just spend US$40 again for the whole darn assembly....
[Nexus 7 Q&A, Help & Troubleshooting] mormopterus:
I have eventually figured out where the touch functionality issues come from: The LCD is touching parts of the touch screen and causes the problems. The solution is to use small bits of double sided tape, folded over a couple of time to make it a bit thicker and place them along the sides and edges to raise the LCD of the screen, et voila, all issues disappear and it works as it should ;)

The one thing that surprised me is that it took me hours of trawling the net where I found virtually nothing except a remark somewhere at some stage about being careful to not have anything conductive touch the digitiser from the inside which eventually made the proverbial light come on in my grey cells. So I hope that posting about it here and in another forum will prevent the odd other person go through the same....
