Disclaimer: This procedure voids the warranty and you can potentially damage your device.
This guide is for informative purposes only. Perform this procedure at your own risk.
This procedure was performed on an MDA2 (aka XDA2, Qtek2020, I-Mate2, etc).
Original Problem: The speaker stopped working.
Note: There seems to be a similar problem but it requires a totally different approach to fix it and it's out of the scope of this procedure. The problem on my device was somewhat different since when the speaker didn't work, the microphone was still functional. So the problem resides on the speaker connector, not the headphone jack.
Note2: English is not my first language, so please excuse any language errors you may encounter.
Let me start by saying that I have a big passion for gadgets and technology, so I was not going to let go on the opportunity to learn and inspect the guts of my brand new MDA2. You may ask yourself, why in the world don't you send it for repairs if it's a brand new device? Well, the answer is very simple, I bought this device over the Internet and I simply lost hope of being helped by the guys at the place I bought it from, they simply never answered or returned my calls and emails. I grew desperate and tired of using the headphones ALL THE TIME, even for alarms and reminders! and as I said before, I was driven by passion and thirst of knowledge and curiosity so I decided to fix it myself (even with the risk of damaging the device in the process). Let me add that I have some basic knowledge in electronics, and by no means this is my first device I fix. I have some experience. (I have fixed some damaged digitizers on a HP Jornada 568 PocketPC and Compaq iPAQ 3630 Pocket PC, fixed a volume slider on a SE T68i Phone and a SE P800 Smartphone to name a few).
Let me tell you that the MDA2 has been by far the easiest to fix. It's very well designed in terms of components and component placement, and the quality of the materials (plastics and electronics) is exceptional. But this is not a hardware review, so I'll start the walkthrough right now...
This is my victim... i mean... MDA2...
These are the tools required to complete the operation:
Torx #6 tool
Very small Phillips screwdriver (+)
Very small flat screwdriver (-)
Credit Card or similar card
A steady hand
Then I removed the SD Card and Stylus.
Proceed to remove the screws, there are two TORX#6 and four small Phillips (+). Be sure to put them on a safe place, they are very small screws and you don't want to loose them.
There are a couple of hidden Torx#6 screws under that black antenna cover, so we need to remove it. The plastic used in this part is not as dense as the rest of the casing (yes, the casing it's made of plastic!), so we need to be very careful not to break it, so apply very little force.
Start by using the flat screwdriver and insert it in the Stylus silo and use it as a lever (as shown), you will hear a "click" when the lock snaps. You will need flexible hands and dexterity since at this point you will also need to insert the flat screwdriver on the side square hole to release this side of the cover. (see next picture).
Here you can see the two squared-shaped holes where you need to insert the flat screwdriver to release the locks. Be very careful since there are some electronic components just below the square holes and do not apply excessive force to release the locks. Remember, the plastic is very thin on this part.
Now the other side, here you need to also use the flat screwdriver as a lever to release the lock on this side. Be very careful, since you will apply some force on the volume slider.
Now with the bottom part of the black cover released, you will notice there are some more locks to release on the top (just on the edge of the SD slot. DO NOT TRY TO REMOVE THE COVER YET!
One more time we need the flat screwdriver as a lever. Insert the flat screwdriver (as shown) but not too deep. Apply very small force in the direction of the arrow and the edge will snap off releasing the cover.
The black cover is now free.
These are the two hidden Torx#6 screws. Proceed to remove them to release the antenna.
The antenna has been removed.
So far so good, now the toughest part of the whole procedure, opening the MDA2 case. You need to be very patient, do not rush since the finish on the case is very easy to scratch and dent. Proceed with the small flat screwdriver and you need to start from the bottom of the MDA2, In my case as soon as I removed all the screws I noticed a small gap on the bottom so I started from that point, but if you don't see the gap, you can start from the headphone jack hole. Please be gentle and don't try to rush.
At this point you can use a credit card to help release the locks that are located all around the case, this way you won't scratch or dent the case. Start counter-clockwise, that is to the left of the headphone jack towards the Stylus silo. Once you manage to release all the locks on that side of the case, just lift it very slowly and the opposite side will snap off very easily. However, be very careful on that side (where the buttons and volume slider is) since in that particular place the plastic is more fragile because of the holes needed for those controls.
Once the MDA2 has been opened in half you can see the three small black Phillips screws (+) (see picture). Proceed to remove them. Please avoid any contact with the electronic components, since at this point any static charge can damage your precious gadget. And also make sure you don't drop the screws or touch the components with the screwdriver, since the MDA2 it's still very alive. See that coin-shaped thing on the opposite side of the screws? That's a LiPo Battery, and it's keeping your data from being erased. By the way, don't try to beat the 20 minute retention time of the battery, you have made a backup right? So go slowly...
Ok. So far so good... This is the speaker, well, actually that's the speaker encased in a small black boxy thing with two gold plated connectors. (see next Pic for a close up).
As you can see, the two gold plated connectors on the speaker container match the two spring connectors on the mother board.
Ok, here we need to be very, very careful. I pulled both springs as shown on the picture above to give them a little more pressure when assembled again and I also cleaned the gold plated connectors on the speaker container. Make sure you apply only the necessary force to pull the springs since they could be disoldered if too much force is applied. Use common sense.
We're almost done!
Now proceed to put everything back together. Remember to put back all the screws in their correct positions and do not apply excessive force or you will damage the thread and make things worse that they where in the first place. Proceed to close the casing by doing the opposite. Start by placing the case on the buttons and volume slider side first then the opposite side.
You may notice that the camera lens will not allow the case to go all the way, but if you do it slowly it will budge.
Proceed with the rest of the assembly in reverse order.
That's it... You can proceed to test the speaker.
My MDA2 has been working flawlessly ever since!!! :wink:
I hope this procedure was helpful.

Excellent post, cheers, and if English is your second langauge then I'd never have known it! There are plenty of people for whom it is their first langauge who can't write as well as you!
Wow. Your documentation is better than what comes with the XDA itself! And your English is better than most people in the US. Great service to the XDA community.
Excellent work, man!
Thanks guys!
I'm glad you liked it!
If anyone has questions about the procedure, please don't hessitate to ask!
Best regards,
Rayan
Great! Somethings in life are free, for opening your XDA II there's Mastercard!!!
hahahahaha
pictures are gone? or is it just me?
did anyone kept a copy?
Sooooo sorry guys... I switched to a new hosting company and recreated my website but forgot to restore those images... I will take them back online ASAP!

please do it asap!
thanks
any luck putting the pictures back online ?
Hello folks!
Sorry for the loooong delay, but as you can see, the pics are back!!!
If you have any questions about the procedure, don't hesitate to ask.

Can someone help me?
I had the same problem myself, except that i've done all the stuff you said and i still have the problem... I can hear the phone ringing, but no sound comes from the device (Alarms, appontments, Media Player, etc). When i answer the calls i can't hear any sound from the people who is calling me... Can someone help me?
:shock:
Gents,
Slightly off topic, so please bear with me.
My M1000 has had a problem ever since I got it. The camera seems out of focus as soon as I try to make pictures past say 1,5 meters. Would the serrated ring around the camera lens perhaps be used to focus the device?
Thanks!
Stefan out
I tried to move the serrated lens just to play with it and see if I could get better focus and remember that it was really hard as if it was glued or something.
However, I didn't apply much force but seems like it's meant to be some sort of focus adjustmet, specially because it looks very close to the lens in my webcam when disasembled.
Should you give it a try, let us know...
is there a way to power an ipaq 3630 without the power adapter but with a different battery? like a cel battery? how is the power conector to the ipaq and battery?
Hi Guys,
I bought one of these and as "good" as it may seem, just warning you off, or at least giving you notice.
The magnet affects the phone and operates the screen by it's self.
Well, that's a little miss leading. What it does is I think, is tell the phone that you have opened the slide.
So depending on your settings, whenever you attach the phone it will either unlock it, open the dialer, read your sms messages or start pressing the soft keys.
Apart from the ridiculously poor delivery (1st class postage arrive 7 days after shipping. A parcel from US came quicker" ) that I don't know whether to blame on them or Royal Mail, I must of got the one adapter with no bloody adhesive on the back! Industrial sticky tape needed, that's if I decide I can live with the unlocking!
*mods* Really sorry, I didn't notice the "accessories" thread. I only hang out in this one, I've only just noticed it.
Sorry to hear you are not very happy with this, i've had one for a while and i reckon its one of the best i've had. as well as being small and discreet the magnet holds the pda even when driving down dirt tracks and over speed bumps.
The magnet does occasionally set off the quick list but it has already been mentioned on this forum that it is activated by magnet it just depends where you put the adapter
i dont know about you guys but im keeping magnets well away from my device.

Do you have a Dual then? Where is your strip to attached the magnet?
After a bit of experimentation, if you place the strip horizontal just underneath the camera (in the center) then the magnet wont set off the phone!
Now I've fixed it with my own tape I'm really happy with it!
i've got mine right in the middle, covering the orange logo, after playi g with it a bit last night it seems to depend a lot on how quickly you move the dual towards the magnet and whether you go staraight towards it or come in from an angle. one thing i havent tried is disabling the quick menu, will give it a go later as i never use it anyway
Hello,
I have gone through the thread discussing InvisibleShield, BodyGuardz, etc... but couldn't find answer to my question. I have ordered the InvisibleShield for my AT&T Tilt. Does it really com-off clean i.e. leaves no residue, or doesn't pull-off paint (logo etc) of the Phone when removed ? I am asking because its the first product I'd be using that requires an adhesive (the solution spray) to apply. I am just worried that when I try to remove it, it should come-off clean as it was never there... Can someone who has experience wrt this answer ?
I apologize if this has been discussed before...
Thanks

The solution is soapy. It's like putting on window tint. It comes off perfectly. I had to send a phone back and removed it.
Thanks a bunch !
Thats great... I can use it without worries then.

The exaggerated, sluggish auto-brightness when recording video is an issue. Watch any of the sample videos on YouTube.
HTCsense.com issues not fixed
In Denmark, there are still problems with HTCsense.com - I mess with it to check stability and MANY times I can not connect to my phone to call it, and the SMS service takes a LONG time to react. Also, I have not yet succeeded in remotely locking the phone.
in the very first batch there was (there still is on mine) a problem where i can not use wifi it turns it self off automatically after saying "Unable to scan for networks"
ill try and grab you some debug logs so you guys are more familiar with the problem.
Internal noisereduction is too strong and it makes all photos look like they are waterpaintings, it should be a quick and easy fix for HTC to take care of.
Image sharpening is too strong set at default zero setting, you have to tune it down to get acceptable shots with less sharpening artifacts in them.
Display powerconsumption is ridicously high, it's somthing HTC have to tune in software if possible.
Possibly too strong antialiasing filter contributing to render soft photos.

HTC Sense is still not working for me...the dashboard doesn't identify my phone's location, the phone does not ring, nor can it be locked or erased. Push messages from the Hub is also not working (HTC Hub via the phone allows me to browse and operate but continues to report that the server is down). The phone number I'm using and related passwords are all correct.
(I'm in Australia).
Im in denmark aswell and have no problems with htcsense.com - perfect sync and responsetime. I had a problem with the updated YouTube app, had the network error many people experienced - but got around it. But after playing a video the hd started lagging like hell.. needed reboot
Sent from my Desire HD using XDA App
I have one to add to the list:
Reduced or loss of GSM/3G/WiFi signal when your hand covers the SIM/MicroSD and/or battery cap.
P.S.
Let's make this list as complete as possible, so we can all point these issues to the HTC customer service.
Will keep an eye on this one!
PLEASE READ THIS: Do not post random issues...PM the OP about your issues and he in return should post a link for the solution or the topic for the issue at hand.

I have to thank you for having the courage to do this thread, honestly im tired of the spam fest of doubled threads in this forum just because people dont use the damned search button, every damned time i come here theres 20 more threads with questions that people answered...
I suggest this for sticky!
An issue I am having is:
I will connect my phone to wifi it will connect fine and tell me I am connected.
I could then later on go into the market and try download something I will have wifi bars but the item will pause download. I then come back out to check if my wifi is still connected and it will say authenticating but doesnt change so I then turn the wifi off and back on. It connects again this time when I go back into the market to download something it works fine.
Anyone else have this issue?

Sorry man.
I have a link that you can add below the speaker problem:
http://forum.xda-developers.com/showthread.php?p=9119804
This thread contains a comparison video, comparing the N95 vs. Desire HD external speaker quality. Also, a few posts down there I explain my experiences about the comparison.
Also, THE SIM/MicroSD cover issue IS NOT RESOLVED!
Some people had covers that stuck out a bit, but could be solved by attaching the cover properly. However, some people like me have the following problem:
When the hardware got inserted into the aluminum body from the bottom-side, it wasn't inserted far enough, causing the following 3 additional symptoms:
-Gap between top of the screen and aluminum body.
-Gap between SIM/MicroSD cover and aluminum body.
-Camera misalignment - Camera is too low behind the lens.
All these symptoms are caused by the hardware installation process, as it is clear that both gaps are exactly the same (about 0.5-0.7mm). The same counts for the camera, it has the same misalignment in mm's.
To be clear: in my case, the SIM/MicroSD cover gap is caused because the hardware is not pushed far enough into the aluminum body, thus sticking outside too far out of the alu body, and making it impossible to get a proper fit simply because it's physically impossible. It also perfectly explains the gap between the top of the screen and the alu body.
The symptoms clearly all connect to the source of the problem: hardware not inserted far enough into the alu body.
I've made a video for showing the gaps, but it's not perfect. The camera misalignment is only visible if you look closely, because the shade covers the misalignment up.

I really don't know, I'm in contact with the HTC escalation team about this, but I do hope so.
I'd be interested in any reply you get because I'm noticing the gaps now I'm looking for them and know what to look for. It's irritating because I hate swapping things but if dust gets in it could cause a lot of problems.

no problem that's the purpose of the thread anyway. I am bored of seeing people asking for the same thing all the time too.
Not sur eif anyone else is getting this, i've got like 12 bookmarks on the bookmark widget and although it's not too bad, it is quite laggy compared to the rest of the phone when you scroll through them ?
Also i've noticed some small gaps around the phone, theres one around the screen i think where a little bit of dust has got into the cracks but nothing has gone through to the screen as of yet, i've only had it for a little over a week ! not happy with this.
Hello Everyone,
I'm in the final stages of a DIY replacement of a G4 Play screen. The new screen is in place and everything accept the battery reconnected. However, I've unfortunately mislaid one small part. The missing part is the small silcon cover that you can see in step 5 of the instructions @ ifixit.com. Sorry for the lack of direct link - this forum won't allow me to paste links until I've posted 10 times.
Does anyone know what this cover does? And if I can't find the original cover then would some electrical tape be a functional replacement?
Thanks for any pointers or advice.
