Possible uses for a N4 with dead digitizer - Nexus 4 Q&A, Help & Troubleshooting

Hi all. ok, so basically i dropped my n4 a few months ago and it cracked the top of the screen a little but it took out 80% of the touchscreen. its only usable now by constantly rotating it in the hope that what i need to touch is in the area which works. I have since bought a new phone (z1) but it seems a waste to have a perfectly ok n4 sitting around doing nothing.
choices are to
a) sell it (not get much for it i'm guessing)
b) fix it (replacement screen and digitizer cost a lot more than its worth doing plus i most likely wouldnt be able to do it myself)
c) repurpose it.
so i guess the real question is, what can i use it for? i cant seem to find any decent remote control apps so that i can use a touch screen of a diff android device to control it so its all a little tricky to do stuff on.
any ideas?

You can buy replacement LCD assembly on eBay for under 130 shipped. If you're in US. The job is pretty straight forward. On YouTube there are a lot of walkthroughs

yeah, i know, i'm in the uk though and they seem to be in excess of £70. given that i mess up putting a screen protector on i dont think i'd be able to put a new screen on. especially given i could probably buy a 2nd hand n4 for about £100 these days it doesnt really seem to a be a lot of point in going to all that effort.

i pulled apart my broken n4 to have a look inside. there's no way i'd bother attempting a repair without the correct tools and lots of skills. it only takes a slight error to mess it up.

I bought an assembly digitizer+screen and it came with all the tools. It took me 13 minutes to take it apart and put it back together. I took it apart later to do the thermal mods too. It's really not that hard. I did it with no static protection, and I was very very careless pulling it apart. I even bent the board with the usb plug on it and it still works.
Seriously just fix it yourself.

well the point of the thread really was for ideas for using it with the dodgy touchscreen. i honestly cant see a point in spending nearly the cost in getting a 2nd hand n4 to repair mine.

Home entertainment console? Combined with slimport or something else this can make your TV a smart tv

Use OTG and connect mouse to the phone through USB. What say?

Repair it.

yeah i'm going to order a usb host adapter. might get a hdmi cable thing too. is there a special type of cable thats required? searching on ebay for them they seem to mention slimport and they are like £20 which is a bit more than i wanted to spend given i'm not sure what i'm using it for yet!
does anyone know if there exists a combined usb host/hdmi/charging cable?

MyTouch 3G slide screen not working

Hey guys, I have had this phone since August of 2010 and personally its really nostalgic, in all reality I prefer it over my Galaxy S, Especially for the Slideout keyboard and seems to have better ROM support :/ But around November 2011 the screen would spaz out not respond and just not turn on. Sometimes it would but so dark it was nearly impossible to see it. I'm not sure if the screen is dead I haven't used it since November when I got my Galaxy S. If the screen is dead, is there any type of repair service? or a way to buy a top half for the screen and replace it?
Look on Ebay, there are lots of these phones for cheap.

Sounds like a loose connection on the cable for the screen. I had the same problem with mine. I'm still using this phone now. Free fix if you can figure out how to take the phone apart & basically unplug & re-plug. Be super careful though! And of course it could be a different problem.
You can buy a new one very cheap in amazon or ebay i dont think it worth to repair
Not sure it's the right place to post this, I replaced the digitizer in my old MT3GS (cracked in my pocket), and ever since, Ive have the screen-spazzing issue as well - wasn't my first time replacing a screen, either. For me, the solution _every time_ has been hit the power button to lock the screen, hit it again to get back to what I was doing... Never had to totally power down to fix the spaz :\
If it'd interest you at all, I'd be willing to send you the phone, charger brick, (and the metal case if I can find the damn thing) for $50+ship - thats what I paid for the new digitizer... If you have better troubleshooting skills than I do, good on you, because I've torn this one down and put back together again at least 2 or 3 times since replacing the digitizer, and can't find a single loose connection - maybe you'll have better luck than me?
Thanks

I called a repair shop I found on craigslist and they mentioned it's more than likely the flex cable, not the lcd screen or glass digitizer. These phones' cables go through lots of wear due to the sliding mechanism. They gave me a 70 dollar estimate, so I just don't slide my phone out anymore to prevent the screen from spazzing out or blacking out for good (it happened to a friend of mine's MTS3g). I've also seen the cable for sale online on ebay or repairsuniverse but I'd rather wait for my full upgrade than invest in it AND risk not fixing it.
I really wanna use this phone again, the slide mechanism is so worn on it you can feel it its kinda tough to do its not springy like it was outta the box, also on ebay these phones still run close to 200 dollars, I would take it apart, as its out of warranty anyways, but I don't have the proper tools to do so, like the mini philips head and the tiny socket wrench. And I hear it is most likely the flex cable but as I said I can't access it.

[Q] Just dropped my Nexus - can it be saved?

So...I just died a little inside...
What I've foolishly done is dropped my Nexus 7 screen side down onto floorboards and as you can see in the attached picture...something has gone awry. I'm assuming that it's the digitiser that's broken??? - is there anything I can (relatively) easily do with limited knowledge of this kind of stuff (via tutorials?)? Or would I be best replacing the device? When the screen is on, the individual bars change colour, cycling through purple, black, but mostly white. The tablet makes the unlocking sound and I can VERY faintly see some aspects of my home screen.
Any help would be appreciated. Rotten start to the new year.
Located in Melbourne, Australia, if that's of any use...
you could check out Tablet repair shops on Craiglist . They usually fix cell phones and tablets for 10 to 40 bucks. Its worth it.
if you are good with tools you could pop it open your self and see if any cables are messed up, give you a better idea on what you need to replace

I try to repair anything I can, Its usually cheaper and also a good chance to gain experience with this stuff. I cant tell you how many screens ive had to replace on my wifes Iphone haha. As far as tutorials go youtube has a whole bunch of them some are more thorough then others Heres a good one to get ya started. Nexus 7 Tear Down
Here is a written tutorial for removing the screen assembly. Between these two you should have no problems! Nexus 7 screen repair
If it still has warranty, you can copy everything you need off the SD card and get it replaced. You can try sending it to a repair shop, but it might be cheaper to buy a new one.
called asus and they told me that it'll cost $220 to replace the device as they won't repair it. I've copied everything over to my pc and I'll probably have a crack at giving it a tear down and fixing it. otherwise I think I'll upgrade to the 32gb as I've found 16gb to be too restrictive. annoying (for me) that there will be a new model in ~6 months time...

just completed the tear down - my battery took ages to remove due to an insane amount of glue (yay for asus build quality?). was interesting to go through the process, but, sadly, the issue with the digitiser persists. I'm going to do some shopping around and see how much I can get the 32gb model for in store, other wise I may even buy (a grey import) one from kogan.com.
Is the screen actually cracked? I could not make it out from the picture.....If not why could you not just get it sent back as faulty? If there is no physical damage how could they tell? But then again you have opened it now............... Good luck.

No cracks and I thought of this straight after tearing off the security stickers Thing is, two out of the three security stickers I was told to remove in the tear down tutorial were already missing. Also, there were several black (ink/oil?) smudge-y finger prints on the copper shielding when I opened it...hmmm
RIP Nexus 7......
replace!
quicker and cheaper...
repair would cost around 70-80% of a new nexus 7

Uses for a N7 Mobo?

I've got a broken nexus 7 that I tore down after the screen shattered with a good motherboard... Is there anything I can do with it? Any possibility of outputting to a screen?
Sent from my Nexus 4 using xda premium
You might be able to check the wiring to the screen on the nexus and see if the wire leads match any of the know configurations of other video sources and possible hard wire it into another video source. You might have to change the resolution to match the screen you use though. Anyway, you will still have to use a keyboard and mouse.
You could scour the internet to see if the LCD panel & digitizer can be purchased somewhere. But possibly that might cost half as much as a replacement.
You could sell it on eBay as a "broken - for parts" listing.
You could see if Asus will quote a repair for you.
If everything still operates normally as far as the USB port & physical buttons are concerned (it still operates correctly as far as software is concerned), donate it to a dev who wants to try cracking APX mode on the N7; either that or become that dev yourself! I suppose there are folks who are willing to try, but don't want to put their own unit at risk of hard-bricking.
Well that's 4 suggestions. Sorry to hear about your device.
Mine shattered too and I took the battery out. Will use it for my replacement (which I got the N73G) if the battery ever dies.
Sorry for your loss.

You didn't mention if the LCD broke as well.
If the LCD is still working, just use a USB mouse with the device.
Otherwise, if the LCD is no good, part-out the unit.
Look to ebay for avg asking prices for various modules.
As for the MoBo, since this system was really designed to be touch-centric, unless you can really create a new ROM for the unit that doesn't rely on touch (the Ubuntu ROM maybe?) it's uses are limited.
With the Ubuntu ROM you might be able to turn it into a web/media/file server. But then again, it may not start up if it can't find all the peripherals it thinks should be attached.

Dropped my N7 what to do now?

So it fell out of the car right on the corner and put a nice big shatter/crack across the screen. I would keep using it, but the touch input goes crazy and starts making the tablet go nuts. What are my options at this point?

I tried using a bluetooth mouse, but the digitizer is making the thing go crazy and I'm not able to make it do anything.
Um, replace the screen yourself or send it in for service. Do you have a case for it?
Was this a trick question? lol
AHHHHHHHHHHHH,
thats like seeing my child (my nexus) run-over by a tracktor.
mmmmmm but yeah send it off or take to a repair shop.....what else is there to do?:silly:

lol i got a friend at work to sell his i-pad to get a nexus 7 ,. within 3 days he FULLY understood why i go so crazy if anyone else picks up any of my devices.
Im a chef and use my tab in the kitchen for recipe searches, creating video's/Photo albums of creating new dish's so on, anyone touches my tab, im there "what are you doin?" lol
within 3 days ...he found his first scratch lol now he's like me,.
"no one touch my stuff you dont need to touch, so dont go near it" " why have you picked up my property? look at your hands, look how long your nails are dont operate my touchscreen with those claws"
mission accomplished looool! :highfive:
Yea I've looked at replacement screens, but they are only a little bit cheaper than buying a new N7. So just gonna wait for the note 8 to cone out and get one of those. I was just wondering if there was something I could do with this now worthless tablet that I hadn't thought of. Thanks for the replies guys. Oh and I did have a case, but it wasn't in the case at the time. I had it in a suction cup mount on the rear passenger door so my son could watch a movie and when i went back there it brushed my shoulder and fell out onto the ground.

ill take it off you for spares eh? lol
More and more places are repairing cracked screens. I saw today that radio shack is offering screen repair starting at $69. Someone I know got a screen repaired for $49 at a computer store (I don't know what device). Shop around before writing your N7 off.

Read twice, flash once
Open the back and pull out the digitizer connection as its separate from the LCD connection then u can use a mouse and keyboard.

[Q] Slightly broken, what now?

I dropped my Nexus 7 today, the screen cracked even though it was in a case. The display is fine, however 1/3 of the touchscreen will not respond.
The bezel is also cracked. Image attached.
So...
Question one: Anyway I can send this in for free with the warranty?
Question two: What can be done to fix it; that won't cost more than the device itself?
Question three: Project ideas to make this thing useful?

Standard warranty won't cover mishandling, which is your case, unless you bought replacement warranty from some retailers;
You can buy the whole assembly for around $100; or you can try salvaging the display by prying it off the touchscreen, buy a touchscreen for about half, then put them together - which is something I'm looking at, though it doesn't look like it can be done in 15;
You can rotate the thing around to control the touch, if you have nothing better to do with your time;
You can use an OTG cable and hook up a mouse to it. This will do almost anything your finger(s) can, albeit cumbersomely;
Nexus has no output to tv or monitor without additional equipment; so best use is to put it on Ebay and maybe recoup some of the cost.
I might get around to the chore soon, and will let you know if you're game.

Well alternatively you could try the fastboot method of replacing/flashing systems (ie: flashing .img files). Also you *might* be able to pick the rom, depending on which portions of the screen is responsive.
Might even be able to do it via adb, if I knew what kind of commands you would give to recovery.
