Compressed air and screen dust

Has anyone tried taking a can of compressed air to the back of the Nexus One in order to try to clear dust away from the screen? I just want it off the center of the LCD screen, don't need to get it out as long as it's not that visible.
What about partially disassembling the phone (like taking out everything that doesn't require you to disconnect flex cables) and then blowing it with the air?
I managed to drop my phone a couple times and that seemed to have caused dust to get under the screen, but I don't want to take it apart completely until I've exhausted all other options. Returning it is also not an option in my geographic location.

Fancy meeting you here
How would the air get into the screen from the back? Isn't it supposed to be sealed?
I wonder if you could move the dust under the screen with static electricity. Get one of those plastic rods like they use for demonstrations in chemistry class and charge it up. Then drag it across the screen over the dust. Just be careful not to discharge the rod onto the metal body of the phone...

Even if you did attempt this...
It would probably leave an unremovable sticky film. That's one of the reasons they tell you not to use it to blow off camera sensors, lenses, and CCDs (you're supposed to use a blower bulb). The compressed air isn't just pure clean air, it's got a bunch of bull**** in it. Not to mention it could quickfreeze the OLED parts and ruin the screen permanently. I would NOT try it. In fact, if you clean the back (battery, SD, SIM area) make sure you hold a piece of CLEAN 100% cotton (best if it's from a t-shirt) over the camera sensor or it will blow off the IR filter. Hope this helps.

I have done it twice. I posted pictures up on here on a different thread the first time around, which was probably 3 months ago. Send me a pm if you want the pictures. It wasn't horrible to do, but I don't know that I'd recommend it unless you're already experienced in these type of exercises. I didn't have any adverse side affects to the screen.

Here's the before and after.. I have pictures of the dis-assembly as well.

Oh yeah, I also found that a can of compressed air wasn't strong enough. I used an actual compressor set at 60-80ish psi I think.

@enisoc lol...
The teardowns online haven't said that there was anything sealing the screen and the front cover, but the cellphone shops here that I've asked have said that they would apply a sealant if I paid them to take the phone apart for me.
It looks like I can't get to the dust with anything short of a complete teardown :-(. I took the canned air to the back of the phone and it didn't do anything, but I also didn't disassemble the battery tray (no torx screwdriver).
@dhendrix11 if you took the phone apart, why did you still have to use a compressor? Couldn't you then just take something and wipe the dust off?

I used a combination of compressed air and a microfiber cloth. I found that it was impossible to find an absolutely clean spot on the cloth, so it basically just put dust back on the phone. I mostly used the cloth to wipe off smudges when I accidentally touched the back side of the lens/touchpanel, and relied on the compressed air to remove the dust. Also, I didn't detach the lens from the phone frame, so it's hard to get into the corners (where most of the dust is) with a cloth.
The second time around I had a lot less dust and tried cleaning it without fully removing the LCD. If you take the phone apart, you'll understand why you might want to leave the LCD attached and simply lean it back from the lens. However, in the end, I didn't find that to be effective, so I took the LCD out both times. I've got a small amount of dust back in there again, but may 5-10% of what I had the first time, and I really haven't noticed it at all, even out in the bright sun, which was the environment that I typically found it most offensive.
As long as you have patience, it's certainly a do-able task. The main reason I did it myself is because it was early on before anyone was reporting confirmed success of getting HTC to fix the issue free of charge with an unlocked bootloader. I didn't want to chance getting billed for it so it was a nice little project instead. Now that many people have proven that HTC will honor hardware defects regardless of unlocked bootloader, I'd go the replacement route if there's not some other reason keeping you from it.

Full breakdown and then put back together

Hi dhendrix11 thanks for the pictures... I've saved everything on my pc.
Cheers

well, I ended up taking my phone apart too, using the iFixit guide and the Youtube video. Actually not as painful as I expected it to be, but for some reason I did not have a rubber microphone channel under the bottom mainboard, and I didn't have a screw at the top left of the top mainboard.
I also didn't take the screen out completely, just pulled it up a bit and used tweezers and a cloth to wipe everything off.
Now I have a like-new screen!

How to replace Nexus Digitizier/Glass

So last week I cracked the glass on my poor Nexus. It took a horrible drop. Well I can't afford another Nexus and I can imagine having any other phone so I figured I'd repair this one. Read up alot on it and watched a video on Youtube. Ordered all the parts I needed I tackled it today.
Well I decided to do a How-To for any other Nexus owner with broken screens.
New digitizer - $40
Torx screwdriver -$5
Philips screwdriver -$5
Plastic tools - Free
Total - $50
Sure beats the $125 some online sites charge.
I would like to thank ifixit and slickromeo.
1. Gather all your tools and replacement glass (known as a digitizer).
Note: Needed tools are a Philips #00, a Torx T4, and a plastic pry tool (Mine was included with the new screen)
2. Set up a clean comfortable area to work in. You may be here for awhile and you're going to want to reduce the amount of dust that could potentially get on the new glass.
Note: I used a folded over microfiber towel to keep the area clean and also add some padding to the hard counter top to prevent even more damage while working with the phone.
3. Power phone off and remove battery cover, battery, SIM card, and Micro SD card. Set aside in a safe place.
4.Our first obstacle is going to be the antennae cover at the bottom of the phone. There are three plastic clips holding it in place (Circled in red). Use a combination of the pry tool, a guitar pick, butter knife, and any other instrument you need to shove in there. It is a pain in the ass... the video I watched online made it seem like it was going to be alot harder than it was, but if you work from left to right, or right to left, and get the outside one unclipped the other two come off pretty easy. Once you get it off set it aside with the battery cover and other things.
Note: Be careful not to break these tiny, fragile clips as they are the only things holding this cover in place.
5. Scream profanities and wipe the sweat off your brow from the previous step. I know it was frustrating and nerve racking trying not to break your precious Nexus.
6. Ok good job now to start the real deconstruction. I'm going to start with the battery tray and then move down to the antennae. There are three screws holding the tray down, but before we start on those there is this tiny ridiculous little "VOID" sticker covering up one of them. I wasn't able to remove it intake, partly because I don't really care about my warranty, but I'm sure with alot of patience and tweezers one could take it off intake and put it back. But screw that just get it off to get to the screw underneath.
7. Now two of these screws is a Torx and the third is a Philips (All in green). Remove them and put them somewhere very safe.
Note: I have four plastic cups set up to place my screws into. These are going into the first one.
8.Next you need to remove the battery tray. There are seven tabs (yellow circles) around it that you need to release using your plastic pry tool. Once those are released gently pull away form the bottom of the phone to remove the tray. Set the tray aside.
9. Now for the antennae cover. There are two more screws to remove, a Torx and a Philips (Orange circles). These screws are going in the second bowl. After the screws are out, gently lift up on the bottom of that cover and it should remove easily. Be very careful not to damage the circuit board during removal.
10. Next to come out is the logic board. there are two more very tiny screws to remove (White circles). Into the third bowl with those. Next you need to disconnect three connections (purple circles). Then carefully go around the perimeter of it with your pry tool and VERY CAREFULLY remove all the little tabs holding it in place. Then simply push up form the bottom of the logic board and slide it out. Set it somewhere very safe.
11. Now onto the actual case of the Nexus. Remove the six Philips screws, 1 at the top and 5 at the bottom . Again there are a series of little clips, five of em, around the perimeter that need to be undone and then the case very easily separates from the screen. Set the case aside.
12. Very simply pry the LCD screen away form the glass digitizer. There it is... the broken glass.
13. Now take your pry tool and from the back of the glass (not the side you would touch if you were using the phone) wedge it between the frame and the glass to separate to adhesive. Once the pry tool is in you can just slide it around the edge of the glass to separate the whole thing. TA-DA your broken glass is forever gone.
Note: The glass is broken and very sharp. Take extreme caution not to cut yourself.
14. Now we just have to put the whole thing back together. Start with the new glass/digitizer. Peel off the plastic protector to expose the adhesive and very carefully put it in place.
15. Wrap the connector that is part of the digitizer around and secure it in place with its adhesive.
16. Take the whole screen assembly and slide it back into the case. Push to secure the clips then replace the six screws that you removed.
17. Slide the logic board carefully back into place. You may have to hold down/more out of the way a few of the connectors. Take it a little at a time and see where it is getting caught up. You got this far don't lose your patience.
18. Snap the back antennae cover back in and replace its screws.
19. Slide the battery tray into place and replace its screws.
20. Snap the gray antennae cover back on.
21. Replace Micro SD card, battery, and battery cover.
22. Enjoy the beauty of your Nexus without a broken screen.
23. Place Nexus in Otterbox Defender case so this never happens again.
I have pictures that document each step but need to be approved by a moderator before it lets me post em... sorry guys

Hey, awesome job on fixing your screen. I would love to see them, my Nexus just went through the same thing 30 min ago. I had it on my lap, and upon stepping out of the car, SMACK, is all I heard. It landed face down and this is the aftermath. It's much worse than it looks in the picture.

Man, that sucks. I know that feeling.
I'll try to put the pictures up to help you out. Or at least a link to my photobucket.

thanks! I just cracked mine yesterday after the phone fell out of my pocket onto a concrete floor. Ouch. I'm giving this a whirl.

Nice, I'll keep this in mind for the day I accidentally break my n1.
I just wish we could somehow jury-rig the Incredible digitizer to our phones =/

I just recently converted to the n1, bought the phone for cheap off craigslists, but notice burn in on the screen, will changing the digitizier also fix the burn in?

Thank you so much for taking the time to do this write up. I just dropped my phone and smashed the screen on concrete 30 mins ago. All is working but the glass is cracked. I've ordered a new Digitizer/Glass from ebay for £30, I just hope it comes by tomorrow.

you can post picture after 5 posts so it should be good now you have 8 posts

I've just completed the work of replacing the broken glass.
I used your guide throughout, it's a shame you haven't been able to post the pictures as it definitely would have helped. I managed to google some dismantling pictures to help with your talk through as it was hard going some times.
Many thanks again.

Another useful tip: run an air purifier aimed at your work station to minimize the risk of getting dust in the glass.

blueboymj: Any chance you can edit your original post and add your pictures so others can use them? I searched quite a lot for a specific procedure to change the digitizer on my poor N1; This was the best, most accurate guide I found. I've done digitizers on a few iPhones (sorry for the profanity) using the ifixit guides, but alas, the ifixit guides were better for them than they are for the N1.
On a side note: The end cap that gives people so much trouble fell off of my N1 in the initial drop. I pushed it back on, and continued using the phone even though the glass was shattered. Removing it the first time was not so hard, I think it was not back on as well as it should have been. Removing it the second time (another story) was much harder. There are two little plastic "bars" on the end cap (step 4 above) that fit into small grooves on the "antenna cover". (step 7) I think the trick may be to possibly pinch the edges of the end cap, while sliding it toward the bottom of the phone. I looked at it after it was open, to see why it was so hard to remove, and realized I had been inadvertently helping it hold itself closed while trying to pry it open. Maybe one of the videos addresses this; I did not watch them.
Thank you to the OP and the responders for this post!

So where exactly did u order the new digitizier and parts from?

Burn in? Like shadowing on the LCD? Nope.
Thats the LCD, and is completely different than the digitizer. The digitizer is just a clear plastic/glass layer that goes OVER the lcd to detect touch.

I had the digitizer and a new case and was going to have a local phone store replace this for me. However, they just gave me some BS story about how you cannot replace the digitizer without also replacing the LCD screen, which I did not provide.
So I've been without a phone (since they have it) for no reason and have to drive out of my way to retrieve it.
Hey crappy phone store, if you're too scared to do the job just say so, don't try to make up a bunch of manure and say it can't be done.
Anyway, I just ordered the required tools that I don't have and am going to give this a whirl.
OP, if you can't post your pics, can you email them to me?

does it fix the multitouch problem?

[FOUND][Q] Water Damage, indicators?

Please where are water damage indicators on tab and how they suppose to look. (pics would be nice).
google din't help, and Ifixit pics din't reveal any clues.
I would like to use warranty by I have no idea if water or something else is the problem (kid was using it when it supposedly died ).
And I suspect water is/was the problem.
Thank YOU.
oh and in case of brand difference. It's AT&T tab.
update.
Water damage indicator is on the back cover of the tab close to connector. (a small square sticker (5x5mm) - its visible on ifixit last picture.
Openig was much easier than expected - with a lot of patience SAFE. (I am not responsible for damage you do ... its just description how I did open mine)
You need #0 Y screwdriver.
1 plastick knife (I sugest get something better as pry tool.)
1 old credit card (cut it in about 3-5mm stripes)
1 needle
take of screws (just remove the black stickers, sugest use needle as pry tool (don't make holes into them). (push on the crewdriver so you don't strip the head)
You don't need pry tool you need something to wedge in to make opening for the ONE creditcard stripe. Something like flat plastick screwdriver. (I modified plastick knife for that)
Dont use anything hard or round as it will make markings on the cover (like screwdriver).
Maybe even the creditcard itself can by modified to be good enought to make the space for the stripes.
now how to... pry open. (don't pry it will go on its own, nearly)
avoid pry !!! on:
TOP of the tab (not realy neded to open top)
speakers+3-4mm
mic
buttons
SIM,SD cards
!!! conection to display (chceck iFixit and youtube videos)
at bottom close to corners and screw openings you should insert stripes (avoid the speakers and add 3mm cause of insulation)
at sides... every where you can except the places I mentioned, but you MUST put someting close to corners - (all 6 places togehter (2left,2right,2bottom)
The Corners are the bigest problem so take extra care so you don't damage anything.
As Corners I mean close to the round part, but not the round part itself.
When you finish putting all the stripes everywhere possible it should be VERY easy to open ... (turn it upside down...) or gently push by connector.
After you mange to open it a bit... there is good place in the corners to pry on.
Don't pull, you will strip the holders. put credit card stripes where it still hold.
Now some more advice:
Fingerpritns are problem - so take care.
battery has two stickers holding it in place (bottom and top) and screw
I suggest after you remove the battery put on the stickers something to cover them (they atract dust,fibers) - I sugest put on them piece of the old creditcard
At some places I used more than one stripe of creditcard -but I think it was not necessary
Oh in case ... I pry between screen and plastick cover. , cause I seen someone trying opening the rear part of the cover and that is BAD IDEA.
Hope it helps someone..

There won't be any way of telling without taking to back off, and and I guess that'll void your warranty. Send it in and and and suspect its died due to water and they can check.

It is not possible to open it safely? I was hoping that I can.

Not without voiding. You can open it, but the probably won't accept bit for repair.
I'd suggest sending it in as so so you can, explain the problem, say you think it's caused by water damage but your not sure as you didn't have it when it died.

i have 1 of mine apart to replace the screen and i have found no moisture tags. on the Inside. It's a tmobile Tab. to open right requires a couple of special tools, you can get then at Ifixit.com i had to buy the Ydriver its the Y-0. and a plastic tool to remove the cover without scratching it.
hope this helps.
Karl

yes I guess that I need at least Tri-wing screwdriver size #0 or #00 not shure which.
Size y0 at ifixid was the only place where they use Y0.. every where else its #0 or #00.
Not shure which one. Web is full of Tri-wing screwdrivers for WII and DS etc but no mention of size. So I will buy both sizes. I need to be sure that it's clean from inside before I ask samsung to fixit.

The marker might be on the battery somewhere
swyped from a galaxy far far away...

it is a Y-0 not 00
just to save ya $9
Karl

I confirm #0 as the right one. #1 too big #00 looks a bit too small.

[Q] Scratched screen- How do I replace it?

The screen on my Rogers HTC Raider is scratched. It is deep enough that I cannot remove by applying polisher. Screen still works but I rather replace the screen as the scratch is visible.
Where can I purchase the screen and replace it myself?

A little advice - I've already replaced the screen on my Raider
Hi, glad someone else is attempting this. I had never replaced a screen in a phone before trying this so for me it was a little hair raising the first time I took it apart. On the back of the phone under the battery cover are 5 screws you need to remove, and one little plastic cover. Under the cover is the connector from the mainboard. Its just a little pop out connection, gently lever it loose before removing the shell to avoid hurting the ribbon.
Once you get this far, flip the phone face-up, and *from the bottom*, gently lever the sides and bottom of the plastic shell away from the screen. Its relatively easy.
Continue working along the edges toward the top until the plastic shell pops free, after that put it face-down again and remove the screws holding the battery holder to the rest of the phone. Pull it up and out to the left to remove it, being careful not to bend the battery contacts as they stay with the rest of the phone. Keep the screws with it, trust me - its easier to remember what goes where this way.
Once you have the battery holder off, put it aside and remove the screws holding the mainboard(s) to the shell. Also you will find three wires with little cup contacts at the ends, gently detach these as well, and when the screws and wires are off, carefully remove the boards. Look closely at the plastic tabs holding them in and you'll see how they come out. When taking them out of the phone you'll need to lift them like you were opening a book - ie. folding them to the right. Underneath are two sockets with ribbon cable connections, one should already be detached - the other can be popped off at this point. If you skipped detaching it at the beginning, now's the time to remove both.
This should leave you with two free boards attached in the middle by a black ribbon. Put them aside and what you have left in your hand is the metal shell, LCD, and digitizer.
NOW..the crappy news. This wonderful, beautiful, powerful, ESPENSIVE phone, is held together by black double-sided tape. Yep. Tape. AND you'll need some more before installing the new digitizer. I ordered mine from tmart as well and it not only comes with the wrong screwdrivers (btw you need a #1 philips bit - VERY tiny!!) but it doesn't come with any adhesive to mount the screen to.
Your new screen should also come with some prying tools, and they are quite handy. The guitar pick one didn't do much but the lever is very handy. You'll need to gently pry the digitizer away from the LCD with this tool being careful not to put too much pressure on the lcd or it might snap. Its only a few mm thick. GO SLOW.. you should have no problems. I've done it a few times now - I'm kinda rough on my toys.
Once you have the part un-taped, its still got the ribbon cable going back behind the lcd. Its connected to a small, thin socket on ther board. You lift a small white lever (remove the tape and save it - reapply it to the new connection) and slide the cable out. You'll need to use your lever again and pry up the lcd enough to slide the ribbon out from behind it. This can be tricky. Again, go slow, be real cautious..the tape is pretty strong. Once you have the panel out completely its just a matter of reversing the process. If you're real careful when removing the original panel, you might be able to reuse the double-sided tape thats in there.. I wasn't so lucky. Mine was covered in glass shards, as I mashed my screen pretty good.
Hope this helps!! I had a rough time the first time, but now its easy for me. I like taking it apart lol..
Let me know how you do! Good luck!

[Q] Advice wanted for opening my NookHD?

I'm preping to open my nook to make sure the battery cable isn't loose. There's this gummy stuff when I got a corner of the case up, but when I looked at the newpower99 battery replacement video it makes no mention of applying double sided tape or the like when reassemblin.
Basically I don't want to end up with a front plate that'll constantly fall off.

I'm pretty sure there's another video that does mention double-sided tape. If you check your office supply stores or well stocked hardware stores, there are two flavors. One of them being "permanent." Either will work if the surface is clean enough. That's going to be the trick. Almost anything that will remove the old adhesive, will also interfere with the new adhesive (Duh). I'd use a minimal amount of Goo Gone on the end of a cotton swab, followed by as many swabs of clear water as necessary. People often use alcohol, and alcohol usually leaves a film but does a poor job of removing the old adhesive.
P.S. I wonder why they felt it necessary to show us the removal and re-installation of all those screws!
