hi. i tried searching a couple forums but haven't found anything regarding a place to buy 8125 parts or a manual to take it apart. i do have the proper t5 driver and just can't seem to get it open. thanks.
Would not recommend disassembly unless you are very experienced
see this thread http://forum.xda-developers.com/viewtopic.php?t=43381
and good pictures here http://forum.xda-developers.com/viewtopic.php?t=43748
thanks a bunch!
Theorist and others who need to do the same, here is the progress I made. The back cover for the 8125/Wiza100 is different than the others. Instead of prying on the side (per the service manual), I pryed at the edges of the keyboard area. The PCB is held in by two clips and a phillips head screw. Everything else should be along the lines of the service manual. Also, if you are just replacing the LCD/touchscreen, you can skip the steps about removing the vibrator, camera, and taking apart the keyboard.
I deassembled my hermes to check out some stuff. I followed a guide so I knew what I was doing. Anyways, after reassemble my keypad doesnt work anymore. I think I must of unhooked the keypad or something. I think it first ribbon, you have to unhook. I didn't know how to reattach it, so I poorly taped it. Heres a pic of the ribbon. I think that should be the keypad ribbon. Anyways, the guide told me to deattach it, but the thing is that it doesnt reattach.. So how do I do it?? Help me please.

It is a push in connector. It has a stiffening layer glued onto it to make it easier to push in. There is no special trick just ensure it's lined up and push in!
You have identified the correct connector (ignore text on first photo is was made for another purpse, but you can see it's a simple push in type.)
The silver surface on the connector is purely for stiffening, if it comes off it can be re-glued.

Thank you soooo much man, I didnt know that it just snapped on together. I thought I might have damaged my phone. Thanks for the disassembling guide links too.
My wizard was slammed with a trunk lid. The clear screen is fine, no cracks, the housing has a scratch where it hit the lid. The lcd screen is half ok. Now I said all that to say: I bought a screen, here is the link:

Now that I have this, it doesn't look like this is what I need.
Here is a pic of the phone turned on.

I can use it with what I can see. So it works fine, its the window that I can't see that is the problem.
Can someone look at this pic and tell me what I should have gotten?
Thanks

My understanding is, You got a wrong part. What you got is a digitizer, it is the one used for touch only and will not be suitable for the type of repair you need. What you need is LCD. The screen on most resistive screen devices consists of 2 parts - 1 LCD and 1 Digitizer attached to LCD by a layer of fine gel and connected by a flex cable, then the whole assembly is connected by a flex to the mainboard.
My recommendation would be to purchase the entire assembly, get a service manual and replace, however, if you had problems deciding what part you need to repair your Wizard, I say take it to the professional.

The way someone is opening and attempting to repair their Wizard on that video is what keeps me employed. Watching someone open their device with screwdrivers and then attempting to re-connect the flex and forgetting half of the screws gives me the creeps, not even sure whether to laugh or cry. Would love to see the repair actually working, rather than someone claiming they found the way to do something without demonstrating any result.
I'm on my 3rd Epic, and this one is going back, too.
Before I send it back, I'd like to disassemble it. I think that the current problem (speakerphone returns static to whoever I talk to) is a soldering issue and may be easily debugged and fixed if I could open up the phone.
Opening up this guy is not easy.
I can remove the visible screws.
I can remove the two screws hidden under the serial number sticker / battery mat.
Even after removing these screws, I can't get the back plate off.
How do I do it?

Opening it voids your warranty and you will be unable to return it if your repair fails.

It only voids your warranty if they can tell you opened it. I haven't run into any tamper-proof stickers.
So do you know how to get into it farther, or were you just poopoo'ing my attempt?

http://www.chipworks.com/samsung-epic-4g.aspx Shows some pics of it disassembled. Maybe it will provide some insight as to how to open it, and maybe not. Better than nothing. Try searching Samsung Epic teardown and digging a little deeper than the first page.

Searched disassembly, not teardown. Thanks.
The link actually helped.
The Epic has 2 microphones?
start up at the top by the power button and use something plastic to wedge between the pieces. DONT user metal, it will scratch or break something.

I've found a teardown picture that illustrates the difficulty...

The problem was the two tabs. I didn't realize how long they were.
There are clips where the back casing sticks to the silver band around the phone. You have to use a thin flat head to separate it. Be careful since the silver band is made of plastic and will crack if bent.
I had to take apart 2 Epics and swap out a faulty keyboard with another one before returning it.

Once I saw how the back cover was snapped on (wide indents that snap to the silver), I was able to remove it. I used a credit card, sliding it down from the volume button, parallel to the phone. Every so often, I'd use the card as a wedge to pry the top off. Eventually, it snapped open.
Unfortunately, I am unable to find a problem. The main microphone works. It just doesn't work in speakerphone mode.
Oh well... I'm on my 4th Epic. I'm holding off on returning them to Amazon. I'll have 3 of 'em sitting around in case I need to make a FrankenEpic.
Do you see any way to tighten the screen slider?

Hey, if/while you're still in there... do you see a MLF-type chip (these are the ones that look like a plastic box with no visible pins because the metal pads are entirely on the underside) that's approximately 3mm x 4mm that has something like "FSA 9480" (or just "9480", or even "Fairchild") written on it? Probably near the USB port? I've read about its existence inside the Epic (and all Galaxy S models), and it seems to be getting enumerated by the kernel during bootup, but I didn't see any actual chip bearing the name in any teardown pics I've looked at. I'm starting to suspect that the "9480" *might* just be IP that Samsung licensed from Fairchild and incorporated into one of their own ASICs (with "9480" being the "IP name" of the chip Fairchild sells as the 9280), but it's really hard to tell.
For anyone who didn't see my other post, or the thread in the I9000 board, the FSA9480 is a USB switch that enables the USB port's two data pins to be repurposed for a) serial UART Txd and Rxd, b) Stereo audio left and right out, c) mono headset with audio out and mic in, and d) JTAG via a special interface called "JIG" that's kind of like Atmel's Debugwire and serializes the various pins of a JTAG interface. It's not actually using USB... it electronically disconnects the two pins from the USB interface, and connects them to the audio/uart/JIG pins elsewhere inside the phone.
Also, if you can see anything that resembles a manufacturer or part number for the USB port, that would be awesome. I know that someone, somewhere HAS to make them, but trying to find nonstandard, offbeat connectors in the millions of items sold by companies like Digikey, Arrow, Avnet, Mouser, etc. is like looking for a needle in a haystack unless you already know the exact part number you're looking for.
didnt really llook too hard, but i didnt see any
How difficult is it to replace the entire screen/lcd? Is it possible to easily remove the entire top off the slider and replace it?
Yes its rather easy you take off the back cover use something like a guitar pick to pop the back snaps apart then from there undo the connections to the main board remove it a few more screws under the sticker and one under the main board i think there is a ribbon cable you have to be genital with they rip really easy also make sure its put back the way it needs to be.. when replacing the screen there are tear down guides all over the new that show it in detail...

Pry bar and hammer should do it!

Today I aquired a HTC Trophy with a cracked screen.
It was not cost effective to have it replaced by the workshop, so I'm attempting to replace it myself.
Following the MicroSD replacement guide by DominikZ, it's been a fairly simple and straight forward process, but I have now come to a point which I'm not sure how to proceed.
I've gotten to the point where I have the two ribbon cables disconnected, and have now separated the systemboard from the front. The front frame now contains the LCD, digitizer and speaker.
Does anyone have some tips on how to proceed from here?
What about the other 3 (black) screws? Torx 6?

Thanks for the tip Lance The pictures were easy to understand, especially when I don't read chinese.
However they did not cover removing the LCD and digitizer.

The three screws on the back of the lcd casing is not screws. Those are threaded cylinders, for attaching the front with the back.
Hey there
how far have you got with repairing the screen as I also acquired a HTC Trophy with a cracked screen. The phone still works so there is no rush but I need to know what I need to repair this unit?
Hey.
No progress so far. I'm not sure how the glass is attached to the front housing, but I have an idea that it might be glued on from the front.
You may be able to extract the glass from the front by using a hairdryer and something thin, like a razorblade. However I have not tried this yet, so I can't say for sure.
Good luck ;-)
There are digitizer replace videos for the htc desire:
youtube.com/watch?v=sXZqIjtFoAU
If the Trophy is build in a similar way you can see how you to remove the glass at 4:00
You can use a hair dryer instead of an oven.
Hi folks, been a long time lurker, came here after looking for a solution to this very problem, so, nlamer here's how to do it, be warned though it's not an easy repair.
(och, I cant post image links until I have made 8 posts :-S )
see attached photos, i'll prob need to do a few replies to post them all.
1:- Strip your phone down and remove the logic board from the chassis, carefully remove the lock tabs to release the ribbon for the LCD & digitizer
2:- Use a heavy duty knife ( I used a stanley blade ) to slice the adhesive holding the LCD to the digitizer, it's only held round the edges so you dont need to go too far in
3:- Peel back the cracked digi and just slice the ribbon, it's attached to the back of the LCD and your not going to be using it again anyway
4:- The LCD is held in place with the light grey adhesive strips, use a spudger to remove it, just be careful not to put too much pressure on it or you will damage the LCD, in my experience it's always better to have a replacement on standby just incase
5:- A quick check to make sure the LCD is still ok, you never know!!!
6:- On the old digi you will need to remove the three clear plastic tabs at the bottom and transfer them to the new one, these feed the LED's to the capacitive button's on the bottom, they are held in place with some adhesive & are not difficult to remove
7:- Remove all the old adhesive and apply some knew strips, I used 3M stuff here and trimmed it to fit but I dare say there are adhesive kits available on eBay
8:- Do the same to the LCD
9:- Line up the LCD with the marks on the digitizer and press it into place, the digitizer ribbon has a small piece of adhesive to attach it to the back of the LCD
10:- Place the display into the chassis, make sure the ribbons go through the gaps in the chassis and everything lines up before committing to pressing down
11:- If all goes well after re-assembly it should be looking sweet again.
Hope that helps yourself & other's out ;-)
Regards
Thanks for the instructions irepairtechstuff. It is greatly appreciated. I almost have my device wrapped up, and ready to go, but I'm having some trouble with the digitzer.
It seems behave as it pleases, and does not register pushes and swipes as it should be. Any tips on this?
Nevermind the last post.
I cleaned the connector with some alcohol, and now it works perfectly
I just got a trophy, I don't understand the adhesive verry well. I though you had to put adhesive on the underside of the touchscreen digitizer (along the edges of the screen) and on the metal frame, under the lcd or the underside of the LCD, but in this turtorial you see adhesive along the edges of the upside of the LCD?????
HELP!
Is there nobody who can help me?
