Hi guys,
I recently dropped my phone on concrete, resulting in a nasty crack across the screen. Last night I received the new LCD/Digitizer and went ahead and replaced the screen (I opted to replace the LCD as well due to the copious amounts of glue used between the two parts). After many curse words were shared, I put it back together again and everything works perfectly... except Wifi.
I was wondering if anyone has had a similar issue, and where I should start looking to fix this? I took the cover off again to check both white (wifi?) cable and black (bluetooth?) cables, and both were connected as they should be.
Any help would be very much appreciated!
Tim
Go back through and check every wire and hook up. That's all you can do.

Yeah, thanks for the reply. I went through it on Saturday very carefully looking for any wire or contact that was loose and unfortunately everything was correctly attached. I did notice that the bluetooth and wifi wire plugs on the lower board were *very* close to each other, so they may well have touched and caused a short. After checking everything over and reassembling the phone, wifi still didn't work I also checked bluetooth and that won't work either, so perhaps my suspicions about the wires contacting is correct.
Note to anyone else doing a repair on this phone: Be very careful that the wifi and bluetooth plugs don't touch each other. It's very easy for them to rotate around in their socket and contact each other. I'm not sure if this caused them to fail in my phone, but it could certainly be the reason why both no longer work.
Cheers
Did you seperate the wires...and did that work.

Yep, I separated the wires and still no luck :/
I also removed the wires just to see if it would at least turn allow me to turn on the wifi, but all it says is "error" in the wifi settings and I can't turn wifi on no matter what I try.
I have exact same problem: after LCD replacement wifi fails with ERROR. Also sometimes no reaction to POWER button - no power off menu neither LCD is off/on. Don`t expect any wires or so i could accidentally damage.
Solved
After dissasembling phone again i found that flex cable has not good connection to mainboard. I pressed connectors, felt some "click", reassembled phone and after booting everything is ok:
wifi, bt, volume buttons, leds while charging operating well. Attaching picture. The connectors are located right under sim card and micro sd card slots, you have to remove full mainboard and flex cable to fix that. Cheers!

That's really interesting. Thanks for the info. It's odd that the phone even functions if the flex cable might be loose. I may have a look and see if this is the problem too when I get a chance.
Yes, phone operate, but really weird behavior - some functions worked, some not, sometimes no reaction to power on button and so on. Hope this helps someone.

Hmm. I wonder if my issue is the same. I have experienced absolutely no odd behaviour other than wifi + bluetooth not working. Everything else works as it used to. GPS actually seems to work better haha. There are two flex cables so perhaps one of them does those two things.

If you haven`t found any other damage: wires, pcb, then most probably your issue is related to exact flex cable. Yes, here are two contacts where flex cable connects to m/b, its clearly seen on photos i attached. My problem was both flex cables become loose...
You're a real man. I would have paid someone to fix my screen.
DIY makes you a real man? lol

My WiFi (and Volume Keys) stopped working after I dropped my phone.
After reading your solution I removed the SIM/SD-Cover and just by pressing from outside, the cable snapped in.
No disassembling, not even a reboot! My DHD works like on it's first day!
Thanks!

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.

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.

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.

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 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*

Hardware
Guys, my beloved galaxy nexus, had a power button problem. I opened up the phone, cleaned up the power but... I didn't figured out that the volume button was soldered to the mainboard. I just forced it and then noticed the sh*t I made. I think the power contacts we're taken apart with the solder.
So, if I send my phone to the Samsung Technical Assistance, there is still hope that it will be fixed or I f**** up my volume button forever?
I'm should never, EVER, open up this phone. I'm feeling a total crap right now.
I just ordered an electronics solder kit and a new flex cable (these are like $5). Going to try to fix it myself.

Hey, did you manage to fix it? i also accidentilly pulled the volume flex cable off the main board when changing my USB charging port. i tried sticking the cable back on with sellotape, obviously didnt work!!
i'd appreciate if you can update with your attempt

Well, I fixed half of it. The down volume button works but the top does not, so I will make another attempt at this week or next. First, these connections are super small -- I didn't have a set of helping hands or magnifying glass to see the connections as well as I should. Second, I'm pretty sure my solder was too thick -- it has to be a pretty small diameter.
I'll probably be able to fix it after my helping hands, flux and small solder arrive. Try it if your handy. I had never solder before and now realize I should have warmed the connection then apply the solder (vs. doing both at the same time).

i tried and failed. i too got the volume down button to work, but then went back in to try fixing the volume up button, ended up damaging the whole area, melted all the soldering points and none of the solder is sticking anymore. My first time soldering too, was worth a try!

Ah glad to hear I'm not the only one. I'm not sure why the volume up key connection is difficult to repair. It's pretty usable -- just vol down and then turn up the volume with the slider.
Hello!
So I've been an idiot. I tried to replace the broken USB charging circuit - which went fine. Until I discovered the volume buttons' connectors just dangling there. To my horror I forgot the volume key having no connector, but actually being soldered onto the motherboard.
I thought I could re-solder, but I managed to rip off clean the connectors, much like in this picture: http://imgur.com/Hg1in1Z.
Note the two on the right. All three came off clean like that.
Can I fix it?
I can change the volume using the software fine, but this seriously will make going into recovery a LOT harder.
Is it possible to boot straight into recovery from the device being off but charging via USB?
Is it still safe to let CM11 handle the updating process for which it boots into recovery itself, installs and then reboots?
I feel stupid for forgetting the only thing I could actually permanently damage, since everything else is a connector.

If that is the picture of your circuit board then it appears that you may be in for some bad news. What you have actually pulled off is the pads that make connection to the circuits. Without those pads intact you will not be able to get a connection and therefore will not be able to salvage your volume buttons. I am not an expert however I have a few years experience soldering small electronics for an automotive supplier and we would scrap any board that had the pads pulled off. Oh and don't beat yourself up too bad, those pads are very easy to pull off, it just sucks that it happened on your GN.

It's not my picture, but does represent the damage quite damn well. I tried finding ways to solder broken pads and there was only hope if leads were visible, which are not for this board (except for ground). I think I am out of luck this time.
Thanks for the fast reply!
Hi
Month ago i replaced battery and since then i have no rear speaker sound. I've tried to fix it by reopening and looking where i didnt connect the cable or something but i cant find the problem. Can anyone tell me where are the cables for speaker because i didnt found nothing on google...

The rear speaker on the HOX sits in the bottom of the rear shell and has two gold coloured spring pins that push up against the mainboard. I have come across the problem when fixing them that the pins get pushed down so they don't contact the board, or can be easily broken off if bent to far. Try bending pins up so the tips sit about 1-1.5mm above the speaker housing. hopefully the picture I've attached shows the pins clearly enough. If this fails to work try replacing the speaker, they are fairly cheap if this doesnt fix the problem you may have a hardware/software fault but try the easy stuff first.

Was thinking about it again and pins do not sit on mainboard but rest on the flex cable that also houses the bottom led's for the home button etc.follow that back and make sure it is connected properly in its connector although it should be if your home button led's are working. Also check there are no small tears accross the flex cable,I have also come across tiny tears across one track before.
It some problema happened with me, but the volume button aren`t working... if someone know something about, help me! i don`t get boot or resset after drain all battery and not boot again!
