How to Disassemble Cingular 8125? - 8125, K-JAM, P4300, MDA Vario General

I managed to knock my 8125 off the counter while charging, landing on the charging connector and snapping the USB connector off the motherboard. Does anybody know where I can find instructions on how to disassemble the 8125 so I can attempt to re-solder it to the board. Any help would be greatly appreciated.

Here's a link to the Wizard Service Manual
http://www.box.net/public/4enzlr1l8c

This is what Ive been looking for....Thanks for the link.
This site is EXCELLENT.

Thank you very much for the link. I was able to take it apart with no problems and then solder the Mini-USB connector back in place on the board, with no problems. The phone works great again, charging and tethering, and transferring data. Thanks again.

hey thanks a lot for the link...and also for Reighvin for proving that its possible cuz the same EXACT thing happend to my brother....

It takes a steady hand, and I suggest a magnifying glass on a stand to help see the 5 contract points. They are tiny and very close together.

im having trouble taking out the back housing!!! the 8125 is a little different to the MDA onthe diagram...who did u do it?

About removing the batter cover, and the top cover around the the camera...
The battery cover is simple. But the camera cover requires to gently pry it up around the edges. Be especially careful around the top of the phone, as there are a couple plastic clips there.
Once the covers are off, there are 4 screws to be removed. One is under a VOID label. Once they are removed, the board just comes right out of the phone.

oo yeah igot that part, i was having trouble with the full housing in the back because i had to open the keyboard adn then take it out...i just hope soldering it back on work and does the job...becuase the usb part, 1 of the 5 small pins is chopped off...

I forgot to unplug it from the car kit before getting off and I pulled the all lot out off car! then I shake it realized that inside the wizard I had a little easter egg surprise!!! So i did what this guy did (but before reading this) and after fews hours I managed to solder the bit back! I got very good eyes!!! and that's comes very handy!!!
The problems is that it lasted fews weeks and now Is giveng me some problems again! so I provably have to take it appart and do it again... But i would prefer to stick a new USB socket in it... Does anyone knows where I can buy one of this mini USB socket?

Now I have the same problem. The connectors drop out, I can't charge or sync. Any suggestions? I don't know to solder at all.

Removing the back housing on the 8125
Hello Reighvin,
I'm trying to take my 8125 apart to remove the camera module. I have the Wizard service manual and was able to take the battery cover (of course!) and the camera cover off. I also was able to take out the 4 screws holding the back housing on. I was not able to figure out how to take the back housing off, though. The Wizard has a little different housing from the 8125. The Wizard manual shows where there are plastic clips holding the back housing in place. I'm not sure where the 8125 housing clips are.
You said in your posting above that after the screws are removed, the back houseing just lifts out. Didn't you have problems with the plastic clips that still hold it in place? What did you use to pry the back housing out after removing the screws?
Thanks much,

Cingular 8125 GSM Reception Problem
I have replaced the full housing of my cingular 8125 and after that I am phacing a problem with it's signal reception. It can find the provider I can make a phonecall but it cuts the line when it tries to get signal from another transmitter point of the same provider. Does anyone have any idea what might be the problem.
Thanks in advance!!

Hi,
I am looking at replacing the full housing on my MDA Vario. (current one is very badly scratched)
Anyone done a full disassembly of this unit? Any tips or things to watch out for?
Many thanks,
Jon

Broken connector

Hi,
My boss has an i-mate PPC (Himalaya), but in putting it back in it's cradle he's managed to somehow bend some of the pins on the bottom connector.
I've managed to gently bend them back to the best I can see, but the PC can't see it any more; I think something in either the cradle or the connector has been broken.
Is there any way to pull it apart enough to get a good look at the connector? Is this something myself - as a reasonably technically-minded person with a decent set of tools - can do, or should I consider getting it repaired professionally?
Anyone got any idea what the warranty will cover?

wizard inside pictures here / keyboard replacement

Hi,
As my wizard dropped in the water it got completely soaked.
I disassembled it to let it dry, see photos attached, put it together again and presto, almost everything works!!!
Just four keys of the keyboard do not work anymore, and as it all happened a week ago now I do not think this will be fixed.
Does anyone know if they do not work because of the water or because of the impact (the Wizard smashed on the street first)?
Has anybody ever fixed a faulty keypad?
Can anybody tell me where I can get a replacement keypad?
Let me know if you need instructions how to disassemble your wizard.
many thanks!
manhattan.
I have no answer to your question, but it is nice to see the inside of the wizard one time.
A couple of other people were asking about disassembly in other posts - so the instructions would probably be handy.
Hi,
I would love some complete instructions on dissasembly as I am about to take mine apart for painting and a hardware mod.
As far as the keyboard goes, you would be surpised how long they retain water, i doubt its a hardware problem, keyboard are pretty much solid state with only a tiny membrane for contacts. However it is this membrane that is most likely to be your problem, the contacts are very close together and covered in a film that can be verry attractive to water as it has rubber over it. So in essence I am saying I bet it is still wet in there, just a few droplets of condensation would do it.
Options, take it a apart and check and leave in a very warm dry place for a day, or II place whole wizard on a warm heater (not hot) for a while and see if that gets it.

Hi,
I also want to know the details of disassembly the wizard.
I think you had better post the instructions o disassembly here as I'm sure there are quite a few people who wuld like to know, me included.
Just a thought by looking at the picture (brave btw!)
Would it be possible to replace the 2,5mm headphone jack by an 3,5mm one and drill out a new hole for the larger connector?
Would be neat if you weren't so dependable on those stupid converters. Not a pretty sight anyway.
Thanks for sharing the photos.
I took mine apart some time ago to fix the stylist problem and when I put it back together some of the keys wouldnt work. The back light wouldnt work either. I found the problem was the little snap that secures the flat cable form the keyboard to the main board. There is a really small clasp that clicks down on the flat cable after you insert it into the connector. Once I took it back apart and snapped it, everything was normal again.
I plan on taking mine apart to change the keyboard form the English/arabic to just English, (anyone know where I can buy the keyboard/keys?) so any instructions you have will be appreciated.
Thanks
The stylii in the picture look like BA stylii.
Do I get 10 points?
will post instructions
OK guys I will put together the instructions and upload them here. I just have absolutely no time now so I hope you can wait a day or two....
Thanks for the comments. I am aware of the little lock that secures the mini flatcable that connects the keypad to the motherboard. I assume that is not the problem as I snapped it securely back in place.
I will try the heater suggestion, I suppose you mean to put the wizard in an oven set at let's say 50 degrees celsius?
The styluses in the photo are from my Qtek 2020. As the Wizard smashed I lost its stylus.... :-(
Sorry the photos do not show the display half of the wizard disassembled... I realised too late that others would benefit from pictures...
Cheers

I dont think I would put it in an oven. I would think that just inside a vehicle sitting in direct sunlight for a few hours would probably do, unless you are in a really cold climate. You may also try some electrical contact cleaner then get some additional heat to it after it evaportates. There is probably something that has trapped some moisture somewhere. Just for info, I dropped my Jamin the other night about 4 feet directly onto a tile floor. It bounced a couple times, ejected the SD card, and reset. But it is working fine. However, I had a bud that dropped his 2 day old Sony Ericsson P900 into water and dried it off immediatly and let it air dry. It worked, but he had problems ever since. It would drop calls and restart all the time. So there may not be a complete fix for it.
Good luck
Hey guys, someone posted the HTC Service manual for the Wizard!
In this manual you see pictures how to disassemble the phone!
It's realy the best manual to use for opening your mobile friend....
Good Luck

I've successfully fixed my girlfriends crappy creative keyboard once after water damage using a pencil. Depending how the keyboard is made, most of the time there will be really thin conductive tracks literally printed on the substrate. The water isn't particularly nice to these tracks and I found that in some parts there was noticale oxidation/corrosion. By very lightly scratching of the affeted paint and then going over it with a graphite pencil this did the trick.
Just an idea, personally I probably wouldn't do it to my vario but then again I'm still in the honeymoon phase with it.
Good luck
I fix phones for a living for many stores and have many phones that have water damage
what you dont do is charge it.. it will burn out the board
what you do is let it dry out, use the service manual and let it dry out in parts
then get white spirit and a toothbrush... dip it in and clean the contacts for yourk eys
once done, again let it try and then see how it goes. thats what i do, although we have a machine that sends out sonic pulses but the above method works too especially when im lazy

Hi,

GSM 01.12.10
OS 1.5.4.2
there is problem in formating the phone.
Even after a hard reset the Os wont boot,

there is a prolem in the flash memory of the phone.
please help me with the assembly and disassembly process so that i can fix it.
Any one?

Broken Display connector! help please :(

So I bought a new housing for my O2 XDA II Mini, during the removal of the display ribbon I broke the little black part on the display connector which holds the ribbon down, and after hours of trying to get the ribbon back in and secured I have bent the pins in the connector to buggery.
The ribbon appears to be untouched, however the connector which the display ribbon goes into is broken.
Is there anywhere I can get hold of one of these little connectors to replace my broken one, obviously very sensitive soldering will be needed to remove the old one and solder the new one in place.
Alternatively, does anyone know any mobile phone repair shops in Auckland, New Zealand who would be able to help out with my situation?
I fear all i'm going to hear back is "the motherboard needs to be replaced", however I am determined not to go through this route, as I am a poor student and the phone sounds as if it functions fine, makes the beepy noise when first starting up on the setup screen.
I was very careful with the actual screen unit while removing it, and I have had signs of life earlier on in the broken connector episode, however I can no longer get anything showing as I can't fit the cable in.
Cheers for any help.
Anything would be appreciated.
"obviously very sensitive soldering will be needed"
And that only can be done by machines/robots. I don't think humans are even able to sloder those kind of connections...
But, could you post a picture? cause I might have suggestions on how to fix it. One would be to bend back the pins on the tiny slot with a toothpick and when done to tape the flatcable, so it stays there.
I've maybe got a spare creen for you.

Wizard Repair Guide?! Mines Broken :(

Hey Guys,
Well, I'm a bit gutted really! I dropped my XDA Mini S on the floor with the charger in and the connector IN the phone has come apart from inside the phone. The little metal bit is practically hanging out. I'm wondering, if i were to take the phone apart could i re-connect the little part? (I have a soldering iron if thats as simple as its going to be?)
Just wondering if anyone had any guides on how to take the phone apart and take a look at whats wrong?
Any help would be so much appreciated!
Many Thanks,
Tom
The service manual is hosted on the ftp site.
ftp://ftp.xda-developers.com/Wizard/Docs_Tutorials/
Hope this helps.
I suspect you probably broke the socket off, but if you have a soldering iron, you might as well try to get a new mini USB connector to work with.
You might try Pocket PC Techs:

I rang them up about an issue I had (screen on the fritz) and they seemed pretty knowledgeable and helpful.
Alternatively there's a company I found today in the UK. I can't vouch if they're good or not.

Good luck.
Well I also have an issue with my wizzard... the mini jack connector (of the handsfree) is a bit loose.
What I am saying is that it does have a good connection with the rest of the circuit and sometimes the sound of the speaker goes off, then I have to insert the habdsfree and tickle it a little bit until it has a good contact.
? have some basic soldering experience,do you think I should give it a try?
Given my device has been apart too many times for me to admit to I thought I'd crack it open to take a pic for you guys. Not sure if this pic will help for those wanting to do some soldering:
Very large pic: http://farm1.static.flickr.com/216/452691530_f47801708f_o.jpg
Excuse the dust.
Ah! That picture at the bottom is exactly what I needed. The metal but at the bottom (the big sqaure) has totally sheared off....bloody thing. Thanks so much for the info on the repair guides. I may give those repair guys a call if i can't get it to work myself.
Thanks alot you guys
As for you WizeMan, it all depends on if you wish to void your warrenty or not. At the end of the day, I installed WM6 on my device so O2 would give me the finger if i tryed to claim. If I'm honest, I'm getting an upgrade next month so I'm not to bothered if I balls it up! Would be nice if I got it working though....

A little bit of a thread hijack but that means it is SIM unlocked.
Let me tell you my news, my friends.
I opened my Qtek 9100 and fixed two serious issues regarding this phone, using... sponge (the one we use to wash the dishes)
1. I put some into the stylus socket (from the thin space it has) and also
2. On the top of the mini jack socket so when i assembled the housing it blocked it from moving (2 of the contacts are no more soldered and i dint have a soldering iron at that time)
Anyway, both operation went ok and my phone is more than fully functioning. Now the stylus is hardly (in a good way) comming out (it first gets longer then comes out).
I wanted to do also the safe singal fix, but didnt find the photos to apply it correclty, so if someone has them, please give link. If you need any info about the "Sponge" Hacks, just post or pm

I'm still trying to get the a new fascia and will probably shove an eraser bit into the stylus spring mechanism to ensure the defect never happens. Also how did you discover the break in the solder joints on the headphones jack? I have a funny situation where the left channel of the headphones doesn't work but I suspected the headphones (the plug has to be pulled at an angle to get any sound out of the left) but now I am thinking it may be the socket itself.
By the way the reception fix pic doesn't load for me either but I unless you truly need it, don't waste your time doing it; I always have all 4 bars and sometimes have 2 bars.

Allright here is the deal.
1. I found out the break in the soldier joints when i opened it. I was really suspicious about it because when i inserted my headphone jack into the connector, i had problem with the contact; the connector was loose and it muted my phones speaker. When i disassembled the phone using the service manual i saw with my eyes that the the joins where f-ed up.
2. I dont really need the signal hack i just wanted to experiment, i have 2.25.11 cingular radio rom and its great.
Btw i suppose you should better use the sponge, because the rubber may wear off but not the sponge...
Thanks for the tip on the sponge. I am going to grab a used but allegedly "like new" body from eBay and also get one of those covers as well.

Needed Button Strip - Anyone have HD2 Parts?

In the process of replacing my lcm, I managed to tear the button flex cable that connects to the mainboard.
I am currently looking for a the button flex replacement. What is the best way of tracking something like this down without going to HTC?
If there is no current seller/merchant available...Um...Is anyone selling an HTC HD2 for parts!?!?!?
Pics included...You can see the button strip, and the little 45 degree angle break on the flex..SUCKS!
I saw the break... Man, that's bad luck...
I hope you find a new button strip. The only other solution would be to solder fine wires from the point I highlighted on the photo. But that is very very very difficult... If you decide to do so until you find a new button strip I would recommend you to let an expert solder it, for example a television-technician. That shouldn't cost you more than a bier for the technician!
Wish you luck!
This just in, I have since purchased a broken hd2 and replaced the button strip. It has a light adhesive and is mounted on two small plastic posts on either end. To loosen the adhesive, just apply gentle heat (blow dryer) and GENTLY peel off. You might come across a stubborn part and want to give it a harsh tug, but you need to methodically peel it up using some sort of flat piece to get from underneath it.
Another torn flex Anyone has spare one or knows where can I get it?
I'm sorry but can't help. I get parts for iPAQs from iPAQ Repairs in the UK. I'm surprised there isn't something similar for HTC parts.
I'm interested in what an 'lcm' is. I've seen it mentioned but with no description.
i need one of these too. i hate htc's policy in not selling parts directly.
This button board should only be like upto $40 usd.
im needing a main board charger soxet broke if price is right ill sell
I have the same problem ....you solved?
where did you buy?

You should be a good electronic technician or know a good one. Otherwise I advice you not to try. I am a ordinary technician and I can say that in my case it was very very difficult and even if I tried hard, I wasn't able fix all connections. Only two of my buttons work right now.
How to Replace Button Strip?
Anyone know of a link showing how to replace this strip? Either I can't find key words for a search or there aren't any good videos out there. - thanks
Good to hear I'm not the only one to snap it so easily. Ordered a replacement from e-bay.
Sorry to dig up an old post but, I need that little wire that connects the wifi/bluetooth module to the main board. I replaced the digitizer in my phone and I somehow jacked up one of the ends on the cable. Anyone out there have parts?
