Hi! First off, if you see my Post Count, it's a nimbly 2, and my status of course is noob. No worries, it's not because I'm not participative or anything, it's just that there's so many info already provided here that there's no need to ask no more. It's like as if I was with my E398 again in MotoModders! And I'm lovin' it!

Anyways, going now to the topic at hand. Some of us here who owns a K800i must have experienced that their loudspeaker stopped working either because: (a) the unit was dropped (b) it already has the defect since you bought it; or © suddenly, it just did!

Either of the three choices, if you don't have an SE Service Center nearby, the store you bought the unit is too far or cannot fix the unit, or you just don't want to go through the hassle of having to wait for your unit to be fixed by someone else, well, read on.

I experienced the problem just yesterday, right after flashing my CID 52 unit using the tutorials provided here. After the flashing succeeded, no sound popped up from the speaker. I failed to identify whether the problem was before or after I flashed, so I tried reflashing. Unfortunately, it still doesn't produce any sound. I tried updating to the latest firmware via SEUS, still no go. So, I did some research, and found these out:

Apparently, most of the recommendations were to bring it back, and on other threads the replies were that they experienced the same thing, it was fixed by returning the unit to the store where they bought it, which took 2 weeks before the unit was either repaired or replaced. That's time I can't afford, since I highly use my phone for taking shots (yep, I use it as my point-and-shoot camera, rather good on it I might add). So, here's what I did:

1. I followed the following link on how to disassemble my unit (you'll need a T6 Torx screwdriver and the smallest philip screwdriver), courtesy of HowardForums by the way:

http://www.howardforums.com/archive/topic/1050515-1.html >>> This is about changing the lens of the front cover of the unit

Note: Make sure your battery, memory card, and sim card are removed before disassembling.

2. When you get to this part in Step #1 STOP! That's all we need for that tutorial.

3. After removing the back panel (the one covering the 3MP Camera's lens, flash, and speaker), spot the UMTS sign, as indicated in this pic:



4. Once spotted, take a look at the hole with black marking beside it, zooming it, it should look like this:



The hole you're looking into is where the speaker sound really goes out. Try to insert your SIM Card and your battery and turn on the unit, open an audio file or the phone's demo. While the sound or demo is running, try applying force on the blacked area beside the speaker hole using your thumb. Try moving from one spot to another within the UMTS range, while applying force still on the area. Soon enough, you will hear the sound come out from the speaker (Yay!). Focus in that area where you applied force into that made the sound come out from the speaker. When you try to remove the applied force, the audio will go out. Eventually, after applying force in different weights and different slides of the thumb, you can eventually make the audio remain without having to apply force anymore. Here's the catch though: Yeah, you may have repaired it, but it ain't gonna be permanent, and as what I've researched, you have to apply force on the speaker area just to make it work. Well, guess what? That method didn't work on my part, and I had to reopen my phone again right when the audio goes out again.

So, for an easy fix, here's what I used:



Yep, just a simple double-sided foam tape. Available almost everywhere. Sure you can use other materials, but this is the cheapest I've got. Cut it just enough to fit the area where you need to apply force into, and attach it (NOTE: Do not expose both sides of the tape, otherwise, you'll be having problems opening your phone next time you'd need to). The area I needed to apply force into my phone and with my friends phones (total of 4 as we all have K800's) was the blacked part beside the speaker hole, hopefully that's the same part with everyone else. After cutting, it should look like this:



As you can see, I didn't remove the sheet preventing the other side of the tape to stick as well. The width of this tape is enough to apply enough pressure on the area once the back panel of the unit is reassembled. Make sure that the tape won't cover even a small portion of the speaker hole, otherwise, volume level will be lessened.

5. After that, reassemble the phone and that's about it! The audio may come out every now and then, but when it does, you won't have to bother disassembling the phone because you can simply apply force on the back panel (in the area where the speaker grills are). Slide your thumb around the area and soon enough the audio will go back. That's the purpose of the double-sided foam tape. Sure saves you from disassembling your phone in case it bogs out again doesn't it?

I'm pretty sure you can remove the UMTS protective cover and check more on the inside to what's really causing the commotion, but without any technical guides available on how to thoroughly disassemble the unit, I can't pretty much risk it. This is my simple solution to the problem, the audio does come out every now and then, but not in a day to day basis. And I'm contented with that. And for those who can live with it, rather than live without having your speaker working, I think this is worth the try. I broke one lock in the phone's back panel. Luckily it didnt compromise the seal of the unit. The lock? Oh, it's just this teeny-weeny thing in the back panel:

>>> The small cost of DIY

Btw, using the modified acoustics here, and it sure sounds better.

Well, that's about it. I think this works with the other models as well that uses the same technical specs, not sure though as I don't have any SE phones that has this problem except for the K8. Goodluck!

NIce tutorial, except i had same problem only with the eirpiece in my k800i after it fell on my hardwood floor. So i went into the service menu by doing this. *>*<<*<* (note < or> arrow mean left or right joystick directions, make sure you follow sequence+stars are stars on ur keypad.) and when to service test and went to earpiece basically to troubleshoot it and no sound was coming out so all i did was bang the top of the phone against my knee and it worked.

Ah, my apologies. I also have a way on how to fix that, which is also posted in the links I placed in my post. If you follow the guide from the link I gave on how to replace the front glass cover of the phone, do the steps listed there up to right before you have to remove the front glass. When you get there, you should have the front of the phone dismantled. You can see the ear piece clinging on the back of the front housing. In the ear piece, there are two pins hanging out. If you look at it, both pins are supposed to connect to the phone's PCB or board. Adjust the pins by lightly applying force in it so that it makes contact with the two golden squares in the phone's PCB (where it should really make contact). When you reassemble the phone, it should now work.

This is much safer compared to banging the phone. Hope this helps.

ooo very nice although this is no use for me

I had this problem today!
I only pressed with my finger on the boxen zone and then the sound cames
Why i do have this error?
When i have again this error should i do make your tutorial?

The same thing happened to my W810, well kinda, sound game out it was just crackly and distorted. I'd only debranded it, the service centre replaced the speaker and it still didn't work. In the end it took 4 weeks to fix and had to get sent off to a SE service centre.

CAn SE tell that you've opened the phone?

SE see that,that you opened the phone!
Because some screws i think scratct it!
