It's been a while since my first pictures were posted for the internal
components, so after permission from site admin gryph0n I have created a guide on
how to take the phone apart.
These are all new pictures which include the never seen before keyboard stripped down to expose the circuit layout.

To open the main body of the phone you need a T5 Torx screwdriver
(I have posted in the past saying a T4 but later found out that was due to my old driver being worn out :oops:)
Remove the four screws, then you need a small flat bladed screwdriver to
unclip the two retaining clips in the middle sides of the body see below pointing to one of the clips, the other one is on the oppersite side.

Once you have uncliped the cover, lift back from the battery cover release end to remove the cover out of the way.
Now you can see the SD card socket

Attached Image


After removing the screen connector strip, can be lifted out of the way
to expose the Keypad buttons and keypad membrane side of the circuitboard. You can also see the internal battery.

Attached Image


Attached Image


The metal keypad membrane support plate can be carefully lifted to show the components underneath.

Attached Image


This next part I do not recommend anyone to try unless you want to risk destroying the keypad. I removed the membrane from the backing plate
and then proceded to seperate the top memberane from the circuitboard.
As you can see this is the matix layout of the keypad.

I went this far in my testing to find the actual cause of the DownLeft problem on the main controller.

Now to move on to the Flip section of the phone.
On the display side there are four rubber plugs, remove these and then the T5 Tork srews underneath them.
Now the hard part, there are two clips either side of the case which have to be lifted very carefully with a small thin blade. You have to be carefull
otherwise you will mark the case as the top cover is plastic.

Attached Image


Once you have done this on the hinge is another clip, lift the cover from the top (speaker end) and carefully slide the cover towards the hinge.
Failure to do this will result in the clip being broken off.
You can also see in this picture the vibrate motor and the magnet used for activating the main screen on and off.

Attached Image


Once you have the cover removed unclip the connector cable then you
can lift out the display circuitry.
Note in the two pictures the earpiece speaker and hands free speaker are one component mounted back to back.

I would just like to add, that no one on this site is responsible for what you may do to your phone. These are pictures showing you the components of the MPx200. If you are not familiar with the inner workings of gadgets, then I recommend that you leave it to the professionals. Remember that it is your phone and you are the only one responsible for what you may do to it...

Just my 2 cents on the matter wink.gif

Thanks for the pics. Any idea where the antenna is? Probably a stupid question, but would it be possible to slap an external antenna port in there somehow? I'd love to be able to do that.

thanks,
james

JamesV, I bellive that there is a member already working on that project, search the forums for it. Wraith already has included a pic elsewhere that the antenna is circled.

Yep the antenna is located in the bottom housing in the box section behind
the battery contacts.

Cool. I searched the forums and the web but nothing turned up. Wraith, would you please direct me to that picture with the antenna circled if it's still up anywhere?

thank you,

Thank you. If I ever get the guts up to try this external antenna mod, I'll let everyone know.

Is it normal for the display to feel a little loose when its not completely opened or closed? I'm just wondering if something needs to be tightened. Thanks

Yes that's fine, as there is not any spring tension at mid point of the flip opening.
There slight movement when the phone is close but it is more stable when it is open.

Re: Antenna Mod.
I made an internal antenna mod to my generic OEM (actual tri-band, non-AT&T) phone.
1. I removed the back cover.
2. I took a piece of thin insulated single-strand wire, and wrapped it around a small "lock washer". (The washer provides good contact with the metal antenna plate, which is glued to the inside of the rear cover - read on).
3. I then took a piece of 3M "super strength tape" (it's got a padded backing), and placed the washer against the metal plate, about a third in from the left - the tape holds it in place and in electrical contact with the metal plate on the rear cover.
4. I ran the wire down the left side of the rear housing, and over the hole for the "rotary volume" selector, or whatever you call it. There is a groove down the inside/side of the rear cover that this thin wire will fit in.
6. The wire was cut at roughly 1.44 inches in length, measured vertically from the bottom of the metal plate antenna (This is a good length for 1900mhz - USA).
The mod has improved reception substantially for me. Especially in weak areas. The reason I used the tape, is so I can undo the mod, without causing any permanent damage.
By the way, I purchased a housing somewhere on the web - it was Orange branded, and this had a different antenna installed to the one in my phone. The antenna in my phone is only about half the width of the rear housing, whereas the Orange one runs the full width. (Motorola replaced my rear housing because of the SIM problem). I tried the Orange one, but it made no difference to the reception, when compared with my original, so I went back to my modded antenna.
When I get time, I will take a v66 antenna, and mount it on the spare rear housing. However, I suspect this will only give me the reception I have already gained from my mod, plus perhaps a bit more, due to the antenna being further away from the users hand when in use. Will report back sometime soon. Hope this helps.

Not really as you would have to strip the keypad membrane which I do not advise.
The problem is possibly oxidisation on the plate of the white part of the keypad
(not shown in my pictures above)

Hey, I'm thinkin about doing the antenna mod, but am gonna hold off until I find out about this.

Was wondering if this type of addition might have adverse effects in terms of our exposure to increased amounts of radiation from the phone, and if so, by how much.

It wouldn't bother me if it increased it a little bit, but if it goes through the roof, then I'll pass.

Thanks
