[Q] Problem changing digitizer

Hi there.I don´t know if this post goes here.Sorry if it doesn´t.I didn´t know where to put it
I was changing the digitizer on my Desire HD and I realize that that I broke the ribbon on the picture.Can anyone help me about what to do?Thanks in advance.

Sadly been there and done that....Only 1 solution-buy another. This process is next to impossible without lots of experience-parts are very fragile! Your best bet is to buy an entire assembly with the digitizer and lcd already attached. Much much easier, but not easy by any means still. Good luck.

Thanks.I´ll do that.

you can fix that.
google ribbon cable fix and follow the procedure
(can't post direct link)
btw.
this you can't fix because the lines are simply too small
(I'm waiting for new LCD)

A bit complicated for me.I will buy another lcd.Thanks anyway.

Hi again.I change the screen but now the wifi won´t work.I can´t activate the wifi.It says error.It´s like i don´t have a wifi antenna.Any help?

wifi antenna
I think your problem is bigger than an antenna. The antenna is the same one as the gps antenna and is fitted in the panel around the flash leds. If you were to enable the wifi and just could not pick up any access points, then I would say it was your antenna, but if you are receiving an error, it is more likely that either the wifi module is damaged or somehow disconnected.
Do the rest of the radio parts work? i.e. GPS, Cell, bluetooth? Can you tell me exactly what the error is that you are receiving?

The cell,3g and gps are working fine.Bluetooh and wifi aren´t.When I activate the wifi I get an error message(it just shows "error").When I try to activate the bluetooth it just does nothing.
Thank you

did you check flex ribbon connection and rips on flex.
(also check volume buttons)

You are right.The volume button are not working!I didn´t try them before.What does it have to do with the wifi?I will open it again.

not much, but it is simple test for the flex ribbon.
open the phone and check the flex connection too motherboard
worst possible thing is that you ripped the flex ribbon during removal from middle chassis

2 areas worth checking-the reciever jack at the top of the phone CAN be put on in the wrong direction-red wire should be towards the top of the phone, black towards the bottom. The long, all black wire running by the camera is the bluetooth coaxial cable and maybe not on its connector properly-kind of pops on when right-check both ends. It also could be damaged/pinched running up through the phone. It could also just be a bad component on the upper board and that whole board needs replacing-a pain after what you've done already.

bluetooth/wifi and volume buttons not working
I think yamFZ6 is right. You likely have a cable not fully seated or a damaged cable. Both the Bluetooth and wifi are on the same chip so it makes sense that both of them would fail together, the volume buttons are a separate module, so they are likely all on a single cable that has issues.
One last thing to try before tearing it apart again, do a full wipe and see if it works properly. This is a long shot, but worth checking and can help with troubleshooting if you cannot find any cable issues.
Good luck,
Let us know what you find.

Looks like the black wire (blue tooth coaxial) near the camera is in toward the battery area too far...battery would be pushing in on it every time and could have broken it...admit that's a long shot...but. Starting to feel like a new "upper" circuit board is in order...hope this helps

Do you know where to buy it?

I have seen it for sale somewhere out there but can't find out where that was now. I would look for a "parts" phone on ebay. usually you get more than a fair amount of usable other parts with it. I just did this for that exact issue plus I needed a 'mid frame'. I got just about everything else with it also as the lower, main board was the problem with that particular phone, Got a usable digitizer, lcd, case, extra wires, camera etc etc all for around $60. You also get the added luxury of more practice/expertise with assembly.

[Q] HTC Desire Components

Hi!
I recently bought a HTC Desire from a friend, seems like he manage to break the minijack (only one headphone works when plugged in - the left one works, both works when i pull the jack further out, but with terrible connection), i tried to clean it - but still the same problem..
Also the speaker is broken..
Are there any places i can get hold of a speaker and minijack for HTC Desire?
Is it possible to solder of those to components and change?
Thanks for all help on beforehand!
Best regards,
DanVazz

Don't know how well that would go, I think you'd be better off buying the upper board (or upper and lower) and replacing that.

So where can I get this "upper board"?
Thanks for quick reply!

ebay I guess?
Also, here's a video of the assembly procedure so you know what part I'm talking about. Check 4:20

Seems like its going to be this one then. Also this will only change the minijack i guess.. Most likely going to buy this one to, if this one will replace speaker.

[Q] No sound, no mic. Software or hardware problem?

So I bought this phone on ebay and it has the following problems
-No sound (Ringer, or earpiece)
-Microphone does not work
-Headphone jack does not work
So since the phone was so cheap $120, I decided to buy it. The hardware parts are cheap (no more than $20 all together) and is an easy fix but I would like to completely rule out that it is not a software problem.
What I have done so far
-Rooted the phone
-Factory reset
-Installed CWM
----and still it does not work.
**THE STORY**
The seller claims that the phone was thrown at him by his GF and that his otterbox saved the phone (mind you is in mint condition, REALLY GOOD OTTERBOX!) and after that it stopped working.
*MY SYNOPSIS*
-If the USB port works why isn't the microphone?(its the same flex cable)
-Headphones don't work, therefore earpiece won't work. Makes sense (same flex cable)
ANY HELP WOULD BE APPRECIATED!!! THANKS IN ADVANCED!!!
-Jean:laugh:

Even though they run on the same flex cable, the cable may not be the problem but rather the actual hardware of the microphone got damaged.
I'm not sure, but I would assume you could make sure it's not a software problem from the factory reset.

What do you mean the actual hardware of the microphone?

What the flex cable is connected to.
For example, imagine a light bulb being lit by a wire. The glass of the bulb then breaks breaking the actual light source, but the wire is still fine. Similarly the microphone could be problematic even though there's nothing wrong with the flex cable.
Just an idea.

Yeah I got you, bad news is now the USB port finished getting completely damaged as well lol. I guess it is a hardware problem. Its ok though easy fix. Should get it done in a couple hours but the thing is having the time to do it.... *sigh*

[Q] Digitizer problems

Hey guys, I'm back while I don't have my iPhone. Now I'm trying to get this damn phone to work again. R800x if you didn't remember. Now, every time I get a new digitizer, It doesn't work. I take the old one off and put the new one in, making sure all contacts in the ribbon are connected to the flex cable connecting to the logic board. Any suggestions to get this damn screen to work again?
Or if anyone has a working, but broken digitizer they replaced, I'll take it

It may be the flex cable, the little cable which connects to the digitizer is part of the flex cable i believe.

Except the front camera works (green and fuzzy with no quality what so ever, but works). That's why I don't think it's the flex.
Just replaced it with an extra laying around. Didn't fix it...

Ah sorry, I meant the front facing camera cable, the green and fuzzy with no quality seems to affirm this.

Static noise when headphones are plugged-in

Hello,
So I have my Zenfone 2 since some months now and since the start, my phone has a problem:
When I plug earphones or headphones, there's a static noise on the left earphone (or on the left side of the headphone).
I contacted Asus, they told me to update my firmware, which I did (I even updated to MM today), but it didn't fix the issue. So they told me to RMA it.
I'm just posting this to know if someone here got the same problem and if he fixed it. I saw a post on a forum which said to deactivate every single sound (notification, etc) and only activate multimedia sounds. For some reason, it worked, and I didn't ear the static noise again but some days later. I tried to do this operation again but it doesn't seem to work.
Thanks for your help,
Best regards,

I thought of that but I don't really know how to do to be honest, I don't wanna break anything. How should I do it? Should I wet the tip of a cotton swab and "polish" the jack input?
Thanks for your reply!

Usually i dont use liquids on my phone. Get a pin and a light source. First look inside of the jack if there is some dust or cotton thingys take out with pin

Hello!
I tried to see if there was some dust in it but couldn't find anything. I, however, used the pin but the problem still persists
I noticed that when I was plugging in my earphone, if I plug in "at the middle" of the jack, there will be sound on the left earphone but not on the right. If I plug it in completely (when you hear the "click" sound), then there'll be sound on the right but not on the left earphone, like I first said on the first post. Maybe this can help you.. I'd like to not send it but if I really have to, I will ._.
Thanks for your help.

Yeah, I've tried 3 different headphones but the problem still persists.

You can clean it with a compressed air can, the kind that is used to clean computers. I have one at home to clean my keyboard from tieme to time and have also used it to clean the headphone jack, since it doesn't use any liquid. You can get one at the local computer store or online from Amazon and similar sites

Hello,
Fortunately, I had a compressed air can at home. I tried to clean it with that but the problem is still here
Thanks for your help though, I really appreciate it.

So I "resolved" my problem.
Since I think my jack is broken, I bought this on Amazon. So I did a little setup so I can properly hear music/sounds:
I have a Logitech G430. When I want to listen to music on my phone, I plug my earphones on the G430 adapter, then I plug the USB cable into the USB-microUSB adapter I just bought, and I plug the microUSB cable to my phone. And it works perfectly!
Some may say It's a pretty rough setup, but for me, as long as it works, that's perfect.
Thanks for your help!

I'm sure a pair of cheap BT headphones is cheaper than that setup. Anyway, if you want to keep using your 3.5mm headphones (I would since mine are very nice and were expensive) you can also try a 3.5 to BT adapter, which is also a cheap and nice option. Music through BT is usually of less quality than through the audio jack, but it¡s better than nothing and you don't need so many cables.
Something like this: https://www.amazon.com/dp/B00UUDZSKE
That one is $19, but you can probably get a cheaper one from a Chinese store such as Dealextreme, GearBest, etc. I have one which I got on eBay years ago and I think it was worth something around €10
