Hi.
I have problem with my u8800. Digitizer was cracked so i replaced it with other one and it doesn't work, it works on old cracked one but on good one it doesn't. Both are synaptics. Can any one help me?
Make sure you purchase a genuine digitizer. Alternatively, you can take it to a professional, but I think they will take a lot more money.
Can you please show me which one you purchased? Also, which ROM are you using right now?
I didn't bought it, i took it from other u8800 i had which was working, but motherboard broke down, and it was lying in the drawer for about half year. Last week I bought another u8800 for parts with cracked digitizer and replaced it with mine, which was working when i last tried it, and it doesn't now. I tried aurora classic but i don't know if it has to do anything with software or it just broke down when laying in my drawer which is less probable.

I don't think it would have broken down while it was in your drawer
It is most likely a software problem. Have you tried changing to a different ROM? Or maybe the original Huawei Firmware?
I tried stock rom, but it didn't worked either. I'll try some more after work.
Update: Changing ROM's doesn't make any difference.

Well where did you buy it?? ebay?? was it guaranteed?? Warranty?? The digitizer could have went out on it already.. Mine was ordered online with insurance guarantee and warranty... lol.. It cost me $60 which is actually super cheap but was worth every bit!! The digitizer is what makes the lcd touch. That or you could have accidentally bent or kinked the ribbon slightly.. Its very touchy.. The screen turns on and everything?? Just no touch??
I got it from blackberry8100parts.com it was $45. Phone works fine just no touch. I checked the ribbon and everything looks good.

The back didn't look alike. When I first put it on the touch screen was fine but a couple of hours later it just didn't work.

Thats strange.. It was for the wing right?? or herald?? I have mine and it works soooooooo perfect.. It takes even less to touch the screen for comands.. I dont understand why it would have gone out.. You are not overclocking your device are you??
They said it was for the wing but the back of the lcd doesn't match. I'm using stock rom right now.
Don't know what your problem might be, sorry - but don't assume just because the backs are different that it's the wrong screen.
I just replaced my wife's Wing's screen with one from one of my older units (whose mainboard died). The screens looked very different, even though they were both T-Mo branded Wings purchased at around the same time.

I'm not assuming its the wrong screen, just stating that the back is different. They guaranteed it will work and it did for a few hours.

Sorry to hijack this thread. giantcrazy, did you get the PM I sent you last week? Please respond via PM so we (really I) don't mess up this thread.

Just today my housemate's T mobile vibrant, the capacitive buttons on the front stopped working, the back light comes on, but the buttons do nothing when pressed, I tried doing a factory restore and they still didn't work. So I restored the nandroid I had just made.
Any ideas on how to get them working again, I think I might try a bit of surgery tomorrow morning. But any help would be GREATLY appreciated, I am a bit newb on Samsungs as my handsets have been all HTC, so hopefully I don't make it worse.
calm down, i think i have good news!
2 months ago i read a topic here of a guy who bough a used phone with exactly the same problem. he flashed through odin stock 2.1 and everything came back working. you should give a try
OK I will try this tomorrow... thanks for the suggestion...
power off phone
pull out battery
GRAB THIS STUFF : http://forum.xda-developers.com/showthread.php?t=1047087
turn on odin
attach phone to pc with usb cable
now while holding down both volume buttons put battery back in.
now you should be in download mode and go back to stock with odin from here!
make sure u put the proper tar file in pit and the .pda file in pda in there proper places on odin and ur set to go.
Enjoy and also make sure u have the proper samsung drivers

I flashed back to stock through ODIN and the capacitive buttons are still not working. Any other suggestions?
really strange... since these buttons and the screen are the same digitizer piece, i THINK if there is no software solution, you will need to replace the digitizer. on ebay you will find it for 20 dollars, not expensive but you will NEED an professional to replace it, believe me, i tried and its hard as hell.
But, if you have money to spend... you can buy the lcd+digitizer set and replace yourself, for about 130 usd

I am guessing that the connector might have come loose, I will have to do some surgery on the Vibrant tomorrow to check it out. I am guessing that because none of the buttons work it is going to be a connector, and going by a tear down video i just watched I am hoping that this means I won't have to go through the whole screen removal thing, cause that looks long and arduous!!
Hopefully it's just a connector!!!!
hmm sounds like driver/firmware issues. the capacitive buttons actually have seperate firmware. did the owner of the device try updating screen drivers/firmware via operator codes or using an app like sgs toolbox etc? i'm using miui so i can't give you instructions on how i fixed the problem for myself when i accidently tried updating screen firmware. but i will say ODIN didn't do squat for me. if you have an app like sgs tools/toolbox on that vibrant find the operator code for maintenance/tech and screen firmware and try updating/reverting and see if it fixes the issue. Ben about 4 months otherwise i'd be more specific sorry.

Nah her phone was in her bag, she pulled it out and the buttons were not working. She doesn't know how to update or anything, and no one had tried updating or anything for 5 months.
Samsungs are so different to HTC, which is what I use that I am struggling to get my head around the different methods of doing stuff on it. I will try to find some drivers or something and go from there. Stupid Samsung releasing so many different versions of the Galaxy S!!
The big issue is that the Galaxy S here in Australia is so different, and the owner of the phone is visiting from America, so it's the Vibrant, so I basically gotta find out info myself, not sure anyone in Australia can help!!!
Is this the thread you are talking about... I am not sure on how you used the code to fix the problem...
http://forum.xda-developers.com/showthread.php?t=854725
I entered the code into dialer and the info was given to me:
Phone's Touch key FW version :0xd
Part's Touch key FW version: 0xd
I pressed the "Touch key FW update" button and it did it's thing telling "passed" at the end but still no love on getting the keys working again.
The lights for the keys all work, but they buttons do not actually do anything... sigh...
to get to those buttons you have to separate digitizer from LCD and this is the hardest part to do since they are taped together. I used hair blower to heat it up and slowly I mean very slowly was pulling them apart. At one point I almost gave up but next day tried again and it came apart.

OK so fixing this is beyond me and no one in Australia has the Vibrant to get parts from....
sooooo.... Is there anyone on here who would be willing to fix this for me? I am prepared to pay!!! Let me know if there is anyone who wants to have a look at this, cause my chances of getting this done in Australia is quite low!!!
I have taken apart quite a few various phones to replace digitizers and such. From experience I can say that even if all the parts are able to be separated with heat they will never go back together quite as good as stock. Also if you do this please do not use a large heat gun as they will get waaay too hot. we have heat pumps with a temperature adjustment that we use here. The lowest setting they have is 100C. I generally set them at 150-175C to remove digitizers.
seeing as how the entire assembly for this phone is around 130 why doesn't she just get a new one with her insurance if she has it? The deposit on an insurance claim for T-Mobile is 130 for me so it is the same financial investment either way.
If she does decide to repair the phone when she gets back to the states I would be willing to help. I do repair various phones and whatnot regularly although most of what comes through here are iPhones (idiot phones). i am in Chicago, but we regularly have phones and laptops shipped to us to repair.
I only found this thread because my buttons just stopped working. A reboot brought them back though.
I hope all works out for her either way.
Ordered new button things from ebay and watched few videos on dismantling and repair of the vibrant then repaired it myself.
All good now! Everything works 100%

Odds are that bunny won't respond back due to the his last post was August lol.
Its not hard at all I saw a couple of vids on disassembling the vibrant and the touch keys are easy
I think if you Google" install ffc on vibrant video" it should pull up
Lol.. thanks for the reply... I figured it out . Ribbon was cut slightly.. replaced it and now good as new

Ok this one goes out to all you cool smart guys out there. I currently have two mt4g's. One is working perfectly fine with the "bad screen", as they call it, and the other is bricked, or no it has a failed pu is what someone told me, but it has the "good screen".
Anyway while just minding my own business on the internet one day I came across a video which shows you how to replace a lcd screen in a mytouch 4G! I was hooked. I could do this I said, it looked so easy! Sure you need some patience, which I got btw. So I was determined to do this, even ordered the tools from repairsuniverse. So about the fourth time watching the tutorial I began to wonder if it would be possible to just swap motherboards instead of disassembling all the way to the screen. Mostly because I still need a heat gun so i could remove the digitized then lcd screen.
So i guess my question is will swapping motherboards solve the pu problem in the mytouch with the good screen? And while I got you here has anyone ever replaced there lcd screen?? Is it worth it??

Yes, if you put the good motherboard in the case with good LCD, you'll get one good phone.
Thanks for the response! This will make the job so much easier
repair options
sorry to piggyback you post but i had a similar question....
a friend of mine is giving me their broken mytouch 4g. it was working perfect but then she dropped it on her kitchen tile (bottom right corner hit i'm told) and now it will not turn on at all.....no cracks or anything, just a scratch in the corner. she says she tried a new battery and tried plugging into AC but no lights, nothing.
i've taken apart enough phones so once I get it i'm not afraid to do some swapping of parts.
my question is, those of you who have worked on this model, any indication where you think would be the problem? i'm hoping the lcd/digitizer is fine since its not cracked but we'll see....and i figured maybe i would just need to do a motherboard swap worst case? is there any other components you think could be shot after the drop? from what i've been able to find its just the 1 main mother board , correct? (meaning there is not 2 parts)
thought MAYBE i'll get lucky after opening it up, and verifying all the cables that possible some cables got jarred loose and thats why it wont respond but not holding my breathe on that.
thanks for the help!
My LG G2 (d802) started having dead screen touch in some small portion of the screen. I just installed Cloudy G3 Rom about a week ago and the problem started showing 4 days after installing the rom. Not sure if there is any connection.
Today i flashed Paranoid Android and i still see the dead touch screen problem is there.
Is it hardware issue? Or still is there any way to find out if its a software issue?
Any help appreciated

can't live without my phone lmao so I havn't done anything yet :/ probably just going to wait till the contract is over with verizon :/
Yesterday I noticed the same problem with mine (D801)...
I think I read somewhere it's pretty common hardware defect.
I'm out of warranty so I'll have to live with it.

Exactly what part needs to be replaced? The display or just the touch sensor?
My one started going crazy. Now it detects press automatically as soon as I turn on the screen. Had to turn off knock-on feature or it would keep turning off and then back on the display again and again.

I was ignoring all the posts about this issue when I browsed the forums, I thought I was safe since my G2 is more than 6 months old and also because some people mentioned it was related to some type of screen (there are two models) and I was on the "safe model", which apparently is not the case. So today I started to investigate the issue and some people end up replacing the whole screen (digitizer and LCD) which I think I'll do too.
Replacing just the touchscreen seems like the cheapest option since the part costs less than $20 bucks, but I honestly don't recommend taking that path since it's really hard to separate the LCD screen from the touchscreen.
So yeah, the whole screen assembly runs for like $70 plus bucks.
Better waste 50 bucks more then when you need to use the liquid and special devices to stick the digitizer to the lcd, it isn't for people who have never done it before. Its especially harder on newer smartphones then from 2010. Thats also the reason why the nexus 5 digitizer isnt sold seperately since replacing it would be much easier and you wouldnt risk your display when replacing the digitizer.
For that 70 bucks you maybe also have the tools included to open the phone and there are many videos which you should follow carefully to replace it well. I would rather pay 70 bucks then going to some repair shop or service center which replaces it for 130 bucks and above. @in_core If you have warranty use it since dead touch isnt your fault and as I read its common so LG have maybe screwed up it somewhere or the rom caused it :/ but i don't really think the g3 rom caused it since people even get that problem who are fully on stock without root.
I'm replacing the screen/digitizer on my Nexus 4.
On the replacement, the screen works fine but the digitizer doesn't respond, while if I plug in my old (broken in half) digitizer, this works.
I notice the digitizer board looks slightly different, on my old one the ribbon says "LGINNOTEK Rev 1.0", while the new/replacement has "LGINNOTEK Rev 1.1"
While I suspect the replacement is simply defective, could it be the different version isn't compatible with my Nexus 4? (It's definitely a Nexus 4 screen/frame)

Same here. I also changed my Nexus 4 lcd and digitizer doesn't work. After RAFP_87 post i did exactly the same and it's working until the first reboot. It would be great if there is a fix.
I'm another one having exactly the same issue. I can sometimes get the old cracked lcd/digitizer working... swap it out for the new one and everything works fine... until I reboot.

Question: Is everyone running 5.0 +? I wonder if it has to do with lollypop.... I'm going to try rolling back to 4.4 and see what happens.
EDIT: 4.4 had no effect, downgrading to 4.2.2 seems to have done the trick... 3 reboots and I still have touch... but what does it mean? Sigh... ****ty non OEM replacement hardware most likely...
Almost forgot about this thread, thought it was just me...
Didn't try swapping the touchscreen over while it was running. However I had already upgraded my phone to lollipop (one of the pre-official releases from the development forum). pixelpump did you try upgrading the phone to a newer android version afterwards?
Noticed as well as the slightly different version the circuit board for the digitizer looked very slightly different - could it be a non-OEM/unofficial/cheap knock off?
Thing is, I've sent it back to the seller but looks like Royal Mail have lost it (it's insured) :silly:
Since rolling back to 4.2.2. everything seems stable digitizer wise. Thankfully, as I'm not really in a position right now to upgrade. In any case, I did try upgrading to 4.3 (which is the the OTA update that pops up after running 4.2.2 for a bit.) and the digitizer stopped working. Seems this new batch of digitizer replacements has incompatibilities with the newer code. This was my 4th screen/digitizer replacement... the last 2 have had this issue, though the 3rd one's problems were intermittent... this last would just not continue working through a reboot. The latest hardware does look sketchy though, the digitizer chip reads "Synaptics" as it should but the ribbon cable reads "Snaptics"... lol, for whatever that's worth.
It sucks to be stuck at 4.2.2 but it's better than not having a phone at this point.

Not really, just Cyanogen and a couple others... if I had the chops I could maybe cook out a rom with an older digitizer driver built in but that just seems like too work Besides, my daughter cracked the screen again already. It's impossible to guarantee Gorilla glass when ordering replacement parts I guess....
