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.

Best regards,
