[REPAIR] LG G2x/O2x Stuck in Headphone Mode - T-Mobile LG G2x

This should be a lesson that while playing around with ROM builds, a problem that shows up and runs across different ROMs that did not once exist before, is probably a hardware issue. I thought I had a ROM that would drop my call audio randomly. Using ADB I noticed the headset jack was calling focus right as I lost my in-call audio. I then found out I could not get sound such as music from the device other than incoming ring and notification sounds. But even this was sporadic.
This is a short guide on how to completely clean your headphone jack to eliminate debris before resorting to a hardware replacement of the jack and flexible cable part which requires soldering.
Symptoms:
1. Audio such as system sounds and music do not play through the speaker, but all sounds do come through a pair of headphones. Incoming call and message notifications do play through the speaker still. This may be sporadic or may happen all at once.
Steps to resolution:
1. Use compressed air to attempt to clean out debris or water.
2. Disassemble phone using a guide such as one to replace the screen digitizer. Only go so far as removing the mainboard. Try this video: http://www.youtube.com/watch?v=-rXX7Rm4gnA&feature=related
3. With tweezers remove the blue tape covering the bottom end of the jack. Mine was packed with dirt and was causing a short between the metal plates (both sides circled in red in this picture).

4. Use compressed air to remove debris. Here was the dirty tape removed.

5. Take a dish of 70% isopropyl alcohol and with Q-tips and clean all contacts around the jack. I even stripped a bunch of cotton of one of my Q-tips to get it inside the jack itself.
6. Use compressed air and gently blow air around and inside the entire jack for a good minute to evaporate all of the alcohol.
7. This is hardest part IMO, but using packing tape cut a large square piece out. Then from that square trace out a replica of the dirty tape you removed. You will want to do this to keep debris and water from easily getting into the phone again. Here is my finished product.

Good Luck!

Thanks! Hope I'll never need to use this, but in the case anyone else does this is awesome.

broken sound on fuze??

hey guys about a week ago all the sudden the speakers seem to have went on my device. I recently changed roms and i still cant hear anything. I first noticed when I slept in this week because the alarm was going off but no audio LOL
anyone have any tips or experience with this issue? I have a feeling its hardware but if any sort of firmware upgrade or anything will fix it id love to know!
if it is hardware related...anyone have a guide on how to crack this beast open and check the audio wiring out?
There is a Service Manual for this phone floating around.
Cracking open the case is easy. I just did so to fix the antenna contacts. Unfortunately I broke my speaker cables when reassembling it, so i will need to do this again when my replacement speaker comes in.
Take off the back battery cover and you will see four screws. Using a very small philips screwdriver, remove the four screws, then with a flat plastic probe (or your nails if they are long enough) separate the back case cover from the keyboard, starting from one side, around the top , then the other side. Leave the bottom for last as that has the USB connector holding it together. The speaker is attached to the back case cover near the top, and has a very short cable connecting it to the circuit board. Careful not to pull the back case off too hard or you can snap these thin cables.

Microphone replacement question.

Hi, my phone mic has stop working no one can hear me.
any one know´s what is the mic replacement for the tornado 2125??
hope any can help me.
thanks.
Strange - already the second with Mic problems for the devices that I watch (all the old ones: Typhoon, Hurricane, Tornado, Excalibur and Vox). It seems that some are offering replacement MICs on ebay, but the more problematic part is to unsolder the old one and re-solder the new on the PBA.
Check first if it is really the MIC and not another problem in the radio part. Try to record a note or a voice tag to see if the MIC is working. Also check if the Headset would work to record.
The mic works ramdom, voice recoder sometimes record the sound other not the radio version is 4.1.13.28_02.61.01 try whit lot of rom´s and the same.
headset is lost but i will try when i found it :S
if you can provide me a newest radio it will very appreciate that.
thanks.
You already have the latest Radio - there is nothing newer for the Tornado. Changing SW will not help if the HW has a problem - and as the recording sometimes works and sometimes not - seems you have a HW problem :-(
Love my phone, but is old know that!
can you help me giving me the correct mic reference?
i will try to fix replacing the bad mic for a new one.
thanks.
See this thread. Search ebay for "microphone dash".
I don't know how you would be able to remove the old mic and resolder the new one. I would not dare doing this. Best option is to open the device (careful! - don't rip off the keyboard cable) - seach for descriptions how to do it - and then clean the PBA from dirt that may have accumulated there.
Edit: all identically looking HTC microphones should work. There is no reason for HTC to have different MIC in the same shape. I found the following item-ids matching on ebay:
310238895928
180534133999
400143006229
400141063057

Mic just work again xD no more problem whit that.
now the Ring Speaker stop working only work´s sometimes and sound rare :S
what is the replacement for that speaker??'
thanks for all.
What did you do to make the microphone work again?
The ring speaker hardly ever breaks, but it is the same for Typhoon, Hurricane and Tornado. It is more probable that dirt has accumulated on the speakers membrane and/or that the contacts to the PBA are not working properly.
If you had already disassembled the device you can take care of both. Check the contacts on speaker and PBA first, as removing and cleaning the speaker is more delicate to do.To remove the speaker from the middle frame you have
to disassemble the device (several manuals available around the net) to its main parts:
Front cover with LCD and PBA
middle frame (with ring speaker, camera and buzzer)
then remove the 3 black screws from the black plastic cover,
now carefully lever up the camera which is glued to the frame with a small double adhesive ring around the lens from inside (really delicate if you don't want to break it!). You could possibly skip that step, but then the next step will require you to bend the flex cable from the camera very much. Never bent it much on my devices, so I cannot tell if that would not break the camera either.
carefully lever between the black cover and the frame (small adhesive frame around the edge) and step by step pull it up to finally remove it. Take care not to rip too fast as you need the adhesive later to keep it stuck well to not vibrate and distort the sound.
now you can access the speaker which should lift up together with the black plastic cover. The speaker is glued with double adhesive tape to that frame - again care to to lift it up.
good luck!
I conected the hands free, to the cellphone and it´s worked again.
i disassemly the phone clean whit isopropyl alcohol and nothing.
only the ringer speaker works somethimes so i thinks is faulty and sound like weird
try to change for another ringer.
thanks for you help!
Ah, that is interesting The 3.rd ring on the plug (the one you do not have on normal plugs) is for the external microphone and shortcut to grounds acts as pickup/hangup button. So it seems that some dirt in the socket has created confusion regarding the microphone?!
To my experience the switch that toggles headset/normal also steers the use of the external/internal microphone. Consequently you should have noticed also the sound disappear (when going to "headset" mode).
When you disassembled the device already, look at the rear part of the headset socket. You see at the left side a gold contact that is normally closed and that opens when you insert a plug. The closed contact must be well connecting or otherwise you are stuck in headset mode. When open (plug inserted) use a wooden toothpick + alcohol to clean the surfaces. Depending on the place where you keep your phone when carrying, the socket eats grid and dust that accumulates at the rear part - so keep the socket clean.

HTC Sensation Headphone Jack

Hey all,
I been looking around for a similar thread, but all of them involve this issue. My issue is that my Jack will not play the right side of Stereo.. At all. I've tried my Gaming Headset, and 5 Diff headphones, its clearly the jack. Thing is I've never dropped the phone, and been really careful with it in general. The Port does not feel loose at all and no matter how much i Twist the plug trying to catch a signal it does not pick up anything. I Also tried cleaning the inside with a shaved down Q-Tip, needless to say it didn't do anything.
Any Ideas?
I have no Warranty
The last time I tried cleaning a headphone jack, I accidentally bent one of the contacts inside the barrel back flush with the wall. That meant one of the contact pins wasn't doing its job.
Take the outer housing off and closely inspect the jack. Shine a torch dow it to make sure all your pins are showing. A surgical needle saved me (great addition to the phone repair kit) You can use it to bend the pin back into position.
Good luck!
Sry for Nekro, just wanted to add a Follow up to the problem. My phone had been recently stolen, when I was hanging out with a not so great crowd, But I just got it back yesterday. And to my astonishment, the headphones started to work if I pushed the jack in further. Turns out it was just Pocket lint.... They musta knocked the pocket lint loose enough for me to grab a weak connection. Just rolled up some Tape and stuck it in and got the Lint out, works perfectly now. Hopefully this will help someone else searching this problem.
Now to just figure out why my Pause/Play , Forward /Backward buttons on both my Headphones don't work anymore....
Thanks a lot Zeal514....I had no sound a all and headphone pin was not going all the way in...swirled some rolled tape in and whole lotta lint crap came out and I can hear now...feels great. Thanks for your post saved me call to HTC helpdesk and time to send phone in.
But my mic is not working...i have old apple earbuds aith no buttons, just a mic attached with earbuds.
Thanks for the tip, I used some 3M Scotch compressed air and after blowing the dirt out of the jack plug, all was good again!

Fix for a low volume in the earpiece during calls

In the last 6 months i had very low volume during calls, I was sure it was a Rom-related issue but even when moving from a AOSP-based rom to a sense one it didn't help.
I've tried the method with cleaning the earpiece with tooth brush - didnt help. so I've took a needle and just entered a few milimeters into the holes of the earpiece, while making a circular movement inside of it.
And now the volume is so strong that i need to put the volume lower it to the middle!!!
Just wanted to let you know in case it's your case too.
FYI: IM NOT TAKING RESPONSIBILITY IF YOU INSERTED THE NEEDLE IN A WRONG WAY AND DESTROYED YOUR SPEAKER, ACT WITH CAUTION!

Can you take a picture of the earphone holes you poked? I replaced my earspeaker while I replaced my cracked screen but the replacement speaker was worse so I swapped back to the OEM one.
I have an idea how the speakers look underneath but would love to know which holes you worked on to enhance the sound experience.
Nothing to photograph here, its not a mods just cleaned the holes of the housing.

Aux Tip Broke Inside Headphone Jack

So I've been keeping my S8 Plus as my backup to my Note 8 since the weekend the N8 came out. My kid sister dropped her iPhone and pretty much killed it so I lent her my S8 Plus until she got a new phone. Well, she only went and broke up the tip of an aux plug inside the headphone jack. It seems the aux cord was pretty old or just compromised somehow. She was in her car when she pulled the aux out of the phone but noticed the tip was stuck inside the phone. Lovely.
In the mean time, I've lent her my USB-C to Aux adapter until I can get the tip out of the headphone jack. I'm averse to using any kind of glue because I don't want to risk leaving any sticky residue inside (hold laughter). I have a smartphone repair kit with some very thin tweezers but they couldn't get a firm grip on the aux bit.
Have y'all seen this kind of issue firsthand and if so do you have any tips to getting this thing out? Thanks!
First check to see of the plug shaft that was broken, is attracted to a magnet.
If so, my first thought would be to take a nail the same diameter, or just slightly more thin as the plug shaft, cut the end off square to the nail shaft, or grind it off. Get a reasonably strong magnet. Insert the nail shaft into the headphone jack hole, and gently put it up against the broken off piece. Place the strong magnet on the nail shaft. Slowly and gently pull and twist as you remove the nail.

What you need is super glue I know you said no glue but this is how I fixed my iPad when this happened and a cotton bud or que tip
You cut the cotton wool off the cotton bud so you are left with the hollow tube then apply a small ammount of super glue on the tip of the tube and I mean tiny amount and then put that in your headphone jack and let it set for 10-15 mins then you should be able to remove the aux tip by pulling the cotton bud out and if you done this correctly there should be no glue left inside the headphone port

Edit here is a link for a laptop but it is the same principle https://www.google.co.uk/url?sa=t&s...QQwqsBCCgwAA&usg=AOvVaw0VTJzWxrN8ZFOD4xbU2nov
Hmm... In my experience super glue typically requires 24 hours to fully cure, right? I think I've heard of applicators you can spray on to speed it up but that's just more liquid being used around this phone which makes me uneasy.
I would second a drop of super glue one a tooth pick then with a light make sure it's centered. That little bit of glue will dry in a matter of 30 min to a hour.

That's how I done it when I done this method when I broke the aux bit in my iPad and now it works fine
I sliced a straw from a juice box and put it around the outside of the broken aux plug then I hollowed out the inside of a pen and put a tiny dan of the gel style gorilla glue on the inside of the pen. slide it down inside the straw and wait for it to harden 5 min pull the whole thing out worked great
