Has anyone replaced the screen on the K900?
Mine cracked and I am wondering if it's easy enough to replace it.

Thanks, I've already ordered a digitizer and screen replacement.
I was wondering if there are better instructions on opening the phone somewhere? What I have found so far, including the video posted above is not too clear.

What I can't tell from the videos is if you pop the screen from the front and then just push the replacement into place, or do you have to open the back and then remove the motherboard, etc..
Can't believe that there is a single video showing how to change the screen on the K900.

So, nobody knows how to pop the screen out and put it back in?
Lenovo's tech support is absolutely clueless in the US, has never even heard of this phone. I haven't found any videos on the web that show how to remove the screen in any detail. Basically, there seem to be two videos floating about, one in Russian with a guy who looks like he's pulling a thread through the middle of the phone, and another video (posted above), which shows a guy opening up the back of the phone, which may or may not be needed in order to replace the screen.
But there is no information which clearly explains how to remove and replace the screen.
Anyone here seen anything?
Back of the phone don't come off. You need to get some thin tool to go between the front screen and the bezel. Be very careful but you need to go around it and gently pry it up. Yeah not something I want to do unless it's last resort or I would add wireless charging to this phone, it sure would fix all the lousy usb ports breaking.

Thanks, mikey199. You are right, the only way to pull it apart is to pry it up.
Unfortunately, this phone is really, really cheaply made. It's the worst I've ever seen. The glass is basically stuck to the frame and parts of the board and it is virtually impossible to pull apart neatly. Seriously, this is terrible workmanship!
I am trying to clean it up and see if it is usable, but while this appears to be a "value" flagship, it's more like a $100 disposable garbage.
I am done with Lenovo

Hey all,
I recently had an accident with my 32GB Touchpad I managed to recover from, so I thought I'd share the story for the benefit of anyone else who encounters the same issue. That said, if you do have this problem, proceed at your own risk. I am not advising you to do anything I did below, rather I am sharing my own experience.
Basically it got dropped around 6-8 feet down a carpeted stairwell. It appeared to land on the side edge with the volume button. To my surprise, the screen wasn't cracked and the buttons responded, but it wouldn't respond to touch.
First, I know this isn't covered by the warranty. [SOAPBOX] Of course, one could just lie to tech support and possibly get it covered, but that isn't how I roll. I've gotten by well in life by being straight with tech support but not taking any bs, not gonna change now.[/SOAPBOX] So, I did a live chat with tech support just to see what it would cost. Short answer, $238 for a tablet I paid $150 for. So no, I decided that if I couldn't fix it myself I'd part it out to others with broken displays etc, or give it to a dev. If I got any money for it, I'd buy an actual android pad.
Once again, PROCEED AT YOUR OWN RISK! I take no responsibility if you damage or brick your device.
Past experience told me that most likely a connector inside was the culprit. I search the forums and interwebs for dissembly instructions. I couldn't find any good ones, but managed to figure it out from the following two links;
http://www.hp.com/hpinfo/globalcitizenship/environment/productdata/Countries/_MultiCountry/disassembly_handhe_2011617223529.pdf
http://www.techrepublic.com/photos/cracking-open-the-hp-touchpad/6253940?seq=8&tag=thumbnail-view-selector;get-photo-roto
If anyone knows a good dissasembly tutorial i missed on youtube or elsewhere, please post it. Anyway, I found the ribbon cables from the panel were indeed partially pulled from their connectors (see attached ribbon 1.jpg). Flipping up the black covers (see attached ribbon 2.jpg) I was able to reposition it and flipped the covers back down.
After a bit of trouble reassembling it (due to my being rough with the side catches around the bezel), my Touchpad is back to its former self, not counting a few scuffs in the plastic around the bezel from by hamfisted work. I'm happy, and my wife is happy I'm not eyeing the Touchpad I just gave her for her birthday . I hope someone benefits from this post, as I've benefited from others' posts here. Just trying to give back.
interesting read. Knowing what you know now, how long would think the whole process would take?

No more than 15 minutes. Of course, I'd try to find a better tool like the one pictured in the linked PDF in my post above. Just gotta be sure the catches around the bezel are free so as not to pull up them up as you lift the lcd panel. They're actually separate pieces of plastic, not part of the bottom mold. One had slide out from under one of the PCBs. I had to remove a few screws to lift said PCB to reposition the catch, otherwise the panel wouldn't snap back in fully.

I definitely give the thumbs up with that tutorial. Very good. A pocket knife blade was my tool of choice to take the cover off!
Thanks for the tutorial.
Sorry to revive the old thread. However, my touchpad is not responding to touch, everything else is functional (it boots perfect and able to update using JC toolbox to latest 4.4.4).
I tried to plug unplug the video connector few times (after disassembling) but still it does not respond to touch. Any suggestion will be highly appreciated.
Thanks in advance.

Do you still have WebOS or a touch enabled recovery installed? That could help determine if the problem is more likely hardware or software. If it is hardware you have already done what I could do.

I have completely wiped the system and removed the WebOS by using JC toolbox. However, I do have touch recovery and while booting in recovery also have problem for touch(does not respond to touch, can select using volume up/down and home button). Does it mean touch screen is now defective? Can it be replaced and is it worth try? Appreciate your input.
Thanks

I would agree it sounds like either the digitizer or control board may be bad. I don't know enough to say more though. As for if it is worth it, do a search on eBay. Used Touchpads sell for under $100. New for around twice that. Nonfunctional units sell for under $50. Maybe you get lucky and can buy one with a working digitizer. If it were me, I would buy a functioning used Touchpad and sell the bad one. Or keep it for spare parts. With current more powerful 10" tablets selling new for $300-500, I'd be careful not to put too much into it.
Good luck!

I couldn'd find any "more powerful" tablets with 32GB ram and wireless charging. Do you know some? I bought a used touchpad then.

You got me on wireless charging. ☺ Not counting that I was thinking of a Nexus 9 or 10, or a Galaxy Tab. A Galaxy Tab Pro 10.1" 16GB goes for $320. It has a microSD slot and an Exynos 5 Octa CPU.

Hello everyone!
I've been searching across xda but haven't found quite my problem (pardon me if there already was a thread).
What happened is that I dropped my S3 and it fell right on screen, and now the screen is totally black. After looking better to it what happened I noticed that display in upper part of screen is broken, and I underline display so you don't confuse it with glass. There are 3 tiny lines visible easily and under bright light you can see that display foil is kinda cracked/shattered.
As I said, screen is dead and when i "unlock" it and pres with my thumbs in upper part, all kinds of colors shows all over display.
The phone function is still working, because when my friend called me, the phone rang but i could not answer the call due to unresponsive/ dead display.
Why I'm actually posting this thread is to ask you if there is some way which I could determine that ALL device functions are still operative (except display). Because if everything else is okay, I would consider ordering screen from ebay and changing it (as seen on youtube). But, if some other things are dead too, e.g. speaker, front camera, proximity sensor; I wouldn't buy replacement kit just to have half of damage fixed.
Also, if someone is familiar to it, how much would it cost to have it fixed in some random service shop (taking that only display is dead)
Thank you!
here is a video i made of the process of replacing the cracked screen. it will help a lot. 3

there is absolutely no need to revive all the threads about broken glass, create your own
Get a new LCD, or go and see one of those blokes who unlock phones.
Guides on YouTube if your doing it yourself.

Look, every time I find myself in a thread, your having a go at someone, back off yea!.
There's no need for the way you are day by day. Your irritable all the time for no reason.
The guy needs help for a specific reason, why stop him?
If you put as much effort into helping people as you do trying to piss them off and tell them what to do, you would be an elite mod by now.

Op needed help 3 months ago, if you look at the date. this guy is just posting his video in every single cracked screen thread, which is unnecessary.
and thanks for the advice, but I think I won't take it
Anyone have a how to for replacing a broken LCD on the L9? I think only the LCD is broken not the touch screen part any way to tell for sure aside from ripping it apart? The lower part of the screen is blurred and I see a crack in the corner but I don't feel it so I think it's just the LCD. The only think I have found is a video showing how to replace the touch screen but they already have it all ripped apart and don't really show how to take it apart.
I figured I would just have to buy a new phone but the screens are surprisingly cheap so I think replacing the screen is worth it if I can do it without killing the phone.
worth trying.
I think the front speaker nook looks like a good place to start prying.
use heat gun to make the glue come off easily.
unless there is an easier way to access from the back of the phone.
I got the screen replaced and the phone still works even.
This video helped a lot. http://www.youtube.com/watch?v=W5YdWeBoM2U while this is a different version of the phone it is pretty close
This device isn't all glued together you just have to remove the screws and it will snap apart. The hardest part for me that is not shown in the video was getting the display cable through the frame the slot isn't wide enough for it to just slide though and I didn't want to break the new screen.
Anyone else with a broken screen give it a try it was only 25 bucks delivered.
After repairing my iPad2, that looks easy.. LOL
I'll keep that in mind if I ever break my L9 screen
yeah there is a video, some one made one, fully detailt!!!
my touchscreen is shadert and later i dropt it again lcd gone black!
so i was happy to see some one make a full video!

Love my phone but had large phone in small pockets and upshot is it fell out and I accidentally drop kicked it across the room.
The plastic piece under the power and volume buttons broke and created a disconnect with the power (constant restarts and even booted into safe mode) so I had to remove it to stop the plastic from continuing to jam the power button.
I have ordered a replacement front/sides for the phone but searched high and low for a fix-it or tear down video.
Anyone know how I can get the old one off and the new one on?
Any Videos around?
The phone is usable but I would prefer it whole. Can anyone help?
Cheers.

Thank you very much for this manual which assisted me in the teardown of my Z Ultra.
I broke the screen in my pocket, glass and digitizer were broke making the phone useless.
The only thing missing was taking the coverglass/lcd off the frame, seems Sony replaces screen and frame as one unit.
I used one of the various guides for Xperia Z, heat and prying tool, and im now ready to put a new screen in, trying to find the best deal now.

Being a Vodafone user, I have some insurance which comes with it. Raised a claim from them. Need to submit few docs. Let's see how it goes.. Is the touch sensitivity as fluid as it was in the original one. Broke my display in my previous phone but after the stock display is changed, the touch was not as responsive

Has anyone tried to replace screen from anything available from aliexpress
I just enquired with mi service center here and they charge a ridiculous rs 6133 for the screen replacement. Anyone have newer updates for a good screen.
Original screen for POCO F1
I thought the back cover could probably the first part gets damage, cause it's plastic. Sorry to hear that. You know you can check witrigs for the part, reliable, and they always sell original parts. Original is the most important thing for cellphone repair for me. Hope this can help you。
Hi,
@Kaadyep
Mine was broken as well. I ordered one on Aliexpress. Seller is Trafalgar (can't post link, rating is 4.9 at the moment, at 100 orders) and cost around 30-38 USD inclusive tools.
Fits perfect and work without issues and no bleeding. The included tools are ok, just the Torx is not fitting. Open the phone is easy but the display is glued. Since the display was broken anyway, i just used one of the included plastic clips and push it under the edge of the broken display, go one round and then you can remove it. The phone still need to be fully disassembled since the flat cable is under the motherboard and battery pack. After that I used very thin double sided tape on the edges to glue the new one in. That is 2 weeks ago and no issues.
Hope that helps.

It could be that the FHD only denotes the 1080 part then the other would be dependend on the aspect ratio. You could say that a panel is FHD but the ratio might be 21:9 (ultrawide), 18:9 (for smartphones), 16:9 (regular), etc.
