Hi,
My friend gave me his broken G1(digitizer+screen).
I've bought new ones and replaced them.
Now i have a weird problem that the lower part of the digitizer is not responding, i cannot open the menu button or touch anything there.
but if i hold my finger for few seconds and then let go then it will open a "quick search".. like it is responding.
is it possible that i've messed something along the way or that the digitizer was not working from the factory?
Also was wondering if there is some program to calibrate?
Thanks
Anyone?
can't help you actually, but i hope this hint helps you:
the g1 has a capacitive touchscreen, it doesnt require a digitizer / calibrating...
but as i don't know how capacitive touchscreens work in detail i can't help you...
I have the same problem :S
I have seen posts about the lower part of the digitizer not working. I think your digitizer is defective. Try wiping and installing your rom again or If you can, see if you can disconnect the ribbon connecting the digitizer to the LCD and then connect it back to the LCD, restart your phone and If it still does not work then your digitizer is probably defective. Contact the seller and ask for a refund or replacement would be the best choice.
Ye I managed to fix it.
I opened and reconnected my phone probably 100 times :S
Oh well, I hope its fixed permanently and Iwon't have to open it again incase it drops out again :S
If you just recently bought the digitizer, i would suggest you ask for a replacement so that problem would not occur again.

Hey guys,
This Note had a faulty flex (the bottom part with the mic and usb port), and so I replaced it with a new part. However, this made something else defunct (loudspeaker). I assumed it was faulty and returned it. This time the second part was also faulty as it doesn't detect the connection of a usb or charger. I have tried about 4 different ones and each seems to have a different issue. What do I do now?? I'm sure i connected it properly, it only is the antenna cable plus one ribbon.
Help please Help :S

make sure its the correct rev # it should be marked... and an oem part or not a cheapo like foxtrot said.
this link has a great pic of the rev#
http://www.ebay.com/itm/USB-Connect...584?pt=LH_DefaultDomain_0&hash=item460b566b00
Does the code on the left also have to be the same or is it just the rev1/2/3 thing?

the code on the left is the model # of the phone... just look for a n7000 flex with the same rev code and you should be good... if that doesnt work..pm me and we can go from there...
Hello guys! Saddly for me my touchscreen stopped working but the thing is that i bought a new screen assembly but i still have the same problem and the same spot doesnt work (on the digitzer, lcd works perfectly). I really dont know what to do i have tried to google my problem but people always solve there problem by replacing the screen and i did the samething and still nothing. I'm running the latest stock rom from at&t now but i have tried to flash viper rom and cleamrom, etc... but i have gotten the same result
i tought that it could be the digitzer connector on the motherboard but it looks new so i cant find the problem...
To be more specific the spot thats shown on the image does work but when i touch it, it shows that iam using 2 fingers when iam only using 1 its really anoying when i use the keyboard. When i touch that spot, the phone starts to select things arround the "dead" spot.
My apologies if i have made some dumb mistakes in the text, i'm from belgium so english isnt my mother laguage.
IF theres no liquid damage.
The phone was working just fine, then mysteriously stopped working in one spot. I would guess replace digitizer (aka glass) But if replacing glass has yielded the same result. Now it gets tricky. Now its either a board level issue or a problem with the Kernel interfacing with its hardware.
Since not a stock device and has been rooted with custom ROM its possible those software mods might have affected it.
My suggestion is do your best to go back to completely stock and hope for the best.

Thanks but iam already on stock i have used RUU to reset the phone, same result. And liqued damage is possible any idea what would help?
Or is it possible that the connector on the board is broken?
As you start to eliminate your possibilities the fixes become more difficult.
If your back on stock everything and still bad then its going back to board level stuff. Meaning the connector on the board or something along those lines.
If thats the case then the fix is near impossible.
Might want to get a good strong magnifying glass out and see what you can find.

Did you ever find out what it was?
My HTC One has a 1/4" section that doesn't respond to touch at all.
Hi
I have the same problem in my HTC ONE E9 PLUS where a longitudinal line along the screen does not respond. Does anybody find a solution for that please?

Most likely a faulty digitizer, replace your lcd assy.
Hi guys. I recently broke my screen on my one and i order a replacement for it. I decided to do the repair myself and everything went well but when I powered on the phone after i had replaced the screen i noticed that the camera, the upper speaker and the headphone jack weren't working. They are all related to the sister board but i can't find what i have done wrong. I have already checked the connections and i flashed a new rom just in case it was a software problem. Can anyone help me with this? Is there a connector that connects all these things to the mother board?

before you do everything/anything see these videos first, or you can follow how to reassembly it, maybe you forget to connect cable/s

I have already watched these and everything seems to be in place. What is weird is that the vibrator which is a component of the sister board is working fine. I' m trying to figure out which cable connects the parts that are not working to the motherboard.

Hi,
I really need your help as I have no idea what to do.
After 1 month of using MI5 Pro Ceramic black I have broke my phone,First the touch worked and there was only vertical lines on the lcd in the spot of the shatter so I could operate but due to my stupidity and of force touching the broken glass these vertical lines started to cover all the screen (Everything worked well on the phone..Sound,Camera and etc..)
So I ordered from Aliexpress LCD + Touch screen for about 70$ (Included DHL Express shipment)
When I got the screen I started to disassamble the phone.. Got everything out,Took out the broken screen and pasted the new screen on the frame (Must say all these aliexpress screens are really bad,0% protection on the screen,Not sure about the LCD quality yet but glass is horrible..Started to scratch even before I used it)
Anyways to our point..
Started to assamble back everything.. Powered on the phone and Yay! Phone is working but...
No Sound,Firstly I checked settings and everything..Ran CIT test and everything that belongs to audio giving force close..
Calibrate Speaker PA test results : State-Get impedance failed!,Speaker Vendor-None
Vibration- FAIL no short and no long
Main mic speaker Feedback,Simulation call test,Front mic speaker feedback test,Top mic speaker feedback test,
everything when I enter it giving FC with that details :
"IlegalStateException:Unable to retrieve AudioRecord pointer for SetParameters() blablala...
Headphone mic feedback test (Called on an uninitialized AudioRecord)
So in short..
No Speaker,No Mic,No headphone Mic..
Now my question is what I need to do from now.. Its not firmware/software problem for sure as before I disassambled the phone everything worked well..
My first guess was the problem is on the Sub PCB but then I asked my self..If the USB-C is working and WiFI antenna giving full signal it means the Sub PCB works so what the hell is the problem? I really hope its not something in the PCB it self as it means throw everything to garbage.. ;<
Hope to hear suggests..
I thought to order the MI5 32GB Black version take out the Main PCB put the Pro Main PCB and put also the ceramic back cover but that I would do only if I know that the problem is from the sub PCB but if Headphone mic doesnt work (Which the Main PCB take care of) then its probably in the Main PCB??
Please help!
you didnt damage the pins on the press connector? is the press connector on the ribbon cable flush / fully inserted ? Are you sure you didnt kink the ribbon cable?
I haven't pulled a mi5 apart, but can only assume its like every other phone i have.

The problem is that far as I understood of how the mi5 built and from how I saw it looks like..The Speaker located in the Sub PCB cover,Vibrate connected to subPCB,And all the SubPCB connected with the cable to the main PCB and I checked it connected good and no any damaged pins from what I was able to see..If there was damaged pins then the phone wont get charged as the USB-C wont be connected as it located in the SubPCB however it does work.. So I really have no idea what cause it..
Also the Headphone mic doesnt work in the tests..Anything related to Audio giving that FC with "AudioRecord" error..
I really must to know what causing it so I will know what to do ;<
Little update,
Just connected a bluetooth speaker,No any sound nothing..
Hi everyone! My MI5 has the same problems, no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can not play music, video offline and online video (Youtube, Facebook, live stream ..). It was happened when i replaced brooken screen. The first time when I turn on, evetything ok, I can play music through speaker, but now everything has gone..! Plz tell me how to slove this problem! Sorry for my poor E!
Hi, I ended up on buying the phone again... It's impossible to fix that problem as probably you did what I did and didn't place the motherboard correctly so a little bent probably happened and that cause to the problem.

Hi there! Care to elaborate a little more? I have also the same problem. I was replacing the rear camera module while the module I had received was broken to begin with. I hadn't really figured this out initially and I tried several times to attach it and test it, perhaps move the flex and retest, and at some I remember I found out the vibration was not there, but didn't pay attention to it as everything was open, until I found out the camera module was faulty in the end, and subsequently discovered also the whole issue with sound/vibration/key backlight etc. Instead of buying a new device, I was thinking to try and fix it, but still I'm a bit unsure about what the problem really was. From what I could figure, I didn't do anything different this particular time the audio/vibration didn't work, with respect to the previous times I attached and detached the motherboard. But is it definitely the board itself and not its flex connecting it to the sub-pcb? Could it be the sub-pcb itself or even both this and the board? In case I buy a new board (perhaps together with a sub-pcb just in case) to replace it which part should I watch out for, not to damage it again. Sorry for the many questions but you seem to be the only source of info for this specific problem.

Hi sorry for late answer,I barley visit xda these times..
After I bought the MI5 again this time in the 64gb version I tested the old 128gb motherboard (The main one) and still same problem with Vibration/Sound (While all sensors work camera too)
Which means its not the sub-pcb problem,Its the main motherboard for sure,Now what cause it?
In my opinion when I pulled of the motherboard to put it on the new screen I insert it in a bad way which made it bent a little and probably the place I bent is where the audio and all the stuff goes on..
I'm pretty sure we cant really do something about that problem as problem related to motherboard it self are usually not fixable,But if you find something I will glad to get a feedback to test on my own bad motherboard so maybe I can back to the 128gb version ;| but I doubt it..

Many thanks for the response! It sheds a little light indeed. I also ordered another phone to replace it as the cost of the motherboard seems to be equal approximately close to a new device. I'm with you, in the same view, I also once placed the motherboard quickly in the chassis without the screw that holds it together, in one of the 50 or so attempts to try and make the camera sensor I was replacing, visible to the OS, and this looseness was the unfortunate one perhaps (?). I too don't expect the sound to work again. I just wanted to double check the issue was not with the sub-pcb, which I did thanks to you. For sure I have no hopes for the mainboard to work again, but still, what keeps me from being certain it is actually the sound card that is the problem, is a very similar case I saw In a foreign forum, and also clues from my device which support the argument that the mainboard might have entered in a kind of diagnostic boot state due to a hardware fault that was apparent, where either some components are not initialized during boot, or their HW resources are taken over from the diag. ports and irqs that are enabled, in which case the issue can perhaps be fixed. For sure whenever I find a good deal on a new motherboard I will replace it, to keep it as a secondary phone, as I liked it quite a bit, but It would be interesting to see if this hypothesis holds or not. Anyway thanks again for the response!
Hi,
I've bought used mi5 with broken screen. After LCD replacement I've found that that phone has problem with sound. Exactly the same as in this thread - no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can't play music, video offline and online video (Youtube).
Someone already did LCD replacement on this phone and probably done something.
But what I discovered on this phone that problem start when battery charge aprox more then 60%.
I did flash one year old ROM via fastboot ( just to verify if it not the ROM problem) and after that everything was fine ( battery level 50%).
I did hardware test - passed 100% fine.
But when I did charge till 100% the problem come back.
That's really interesting finding... Can you tell me the same steps you did like which rom you flashed and all of that? I will check it with my dead phone maybe if I will have the same thing like you we can point on something...
mi5 lcd replaced touch not working
I bought a mi5 mobile in singapore. My display was damaged. I changed many display in india (checked in many shop). only work display (lcd). Touch not respose. please some one give solution. thank you
have same problem with op
my phone get damaged by water so im rush turn it off and open everything then go to dry it... and problem with speaker etc doesnt work just like op please help i really doesnt have money to buy new phone this month
Exactly same problem with me, just replaced the rear camera and the problem occurs
No sound, no vibration, nav led not working at all, playing video not working
Even playing sound via bluetooth speaker not working too
I believe there is something wrong with the mainboard
can anyone point out which part of the mainboard responsible for the lower board?
The lower board works well though, I tested it using other mainboard

For me the problem was that after the screen replacement (It may also apply to you after you replaced the rear camera..)
When I put back he main motherboard it wasnt sat properly,I put it beneath a small plastic holder and when I closed everything and screw and all..Problem appeared and when I rechecked motherboard I found out it got bent in the right down side and that's probably what killed all the sensors,sound and everything..
Of course that what happend to me..There is plenty of other reasons that may cause to what you experience..

I believe the chip or something similar, that control the sensor, led, vibration etc, was broken because we put it the wrong way
now we need to find which chip it is and replace it
which part of the right down? near the signal cable?

If you just checked and saw you put it wrong as I did,On the little plastic which made a little bent then I guess you lost..I would just buy new motherboard on aliexpress or just give up and buy a new phone..
As you cant really know (I mean from our side..) if its a chip related there or if its the bent it self which made problem on the connection on the board it self..
And yes I was speaking about the right side near the signal cable where you need to install the motherboard from that side where there is a little plastic like holding the motherboard..When I did the reinstall by not checking I put the motherboard on that plastic and after I closed everything and all screws got back I discovered that problem..

yeah, it means it's the same mistake as mine, that little metal thing that hold the motherboard, I forgot to eject the sim card tray and when I pull my main board it was stuck, got a little bent from there
Just wonder if anyone have the schematic for mi5 mainboard, since I'm curious and want to find a way to repair it
Not because I'm in despair of needing a phone, this MI5 is my secondary phone
Just because of the curiousity, that's all
