MDA Vario II Dis-assembley

26 posts in this topic

Posted · Report post

Ok, so i got my MDA Vario II on Friday, and it's less than a week old so what do I do? Take it apart and write a guide for all you good people :D

Ok first things first, THIS WILL VOID YOUR WARRANTY

The device in question is an MDA Vario II but these instructions will probably hold true for all hermes varients (with maybe a little modification)

You will need the following:

  • A HTC Hermes
  • T6 Torx Screwdriver
  • A small Philips Screwdriver
  • Flat Blade screwdriver
  • Case opening tool (old credit card will do)
  • Decent degree of technical skill
  • A need to void your warranty
  • A LOT of courage :)

I'm working on the device face down at the start for reference.

Remove the back cover, battery, SIM, memory card, ariel bung.

Unscrew the four visble T6 screws (top left just below the ariel extention, bottom left below the battery, bottom right inside that silver lanyard attachment which will fall out after you've undone the screw, top right under the void sticker)

Turn the device over so the screen is facing you, slide the keyboard out and press down on the device on the bottom left corner, to the left of the usb and reset button, and slide your case opening tool into the opening youve made (there goes the adult content filter :)) and move it to the right and you will feel the sections come away, slide it up the length of the device making sure the casing comes away and up over the top (it gets tricky here as its quite tight) and round the other side so the back section of the casing can come away in your hand, the battery cover locking button will most likely spring out at this point so get ready to catch!

Turn the device back over so the exposed mainboard is now facing you. Cunningly hidden in the ariel (the big black thing at the top) is ANOTHER T6 screw so undo that, then on left hand side, in the middle is a small ribbon cable connector to the keyboard, disconnect that. Slide the screen halfway out (you MUST do this otherwise you could tear the ribbon cable connecting the screen) and then gently, using your flat blade screwdriver prize the mainboard out from the chassis from the top first then bottom.

Turn the mainboard on its side to the right and gentley remove the silver tape on the RF covering (silver bits) and the ribbon cable. Using a flat blade screw driver, gentley lift the socket connecting the screen off the mainboard. I recomend levering inbetween the plug and the socket ot avoid tearing the conacts off the cable.

You can remove the keyboard circuit board from the chassis by prising up one end and lifting the board away and unsticking the ribbon cable followed by the button pad.

You will also notice, to the right of the keypad 4 screws holding the screen assembley on, undo them using your philips head screwdriver. This middle section will now simply lift off.

Take the four screw out of the bottom of the screen section and run your case opening tool along the edges and the back should pop off after you have disengaged all the clips, you can now remove the keypad/screen camera if you so wish :P

To re assemble: do the exact opposite :)

This is my first disassebley guide so feedback is welcome :D

Pictures are coming when i have time/desk space :(

Enjoy

Phil

Pictures would be nice :)

I'm interested in taking a look at the back of keypad to see if anything can be done to make "T" key work when pressed normally (it works only if I press its upper-right corner, like something was misalligned underneath)

Also, my rubber grommet that holds the stylus fell out, I'd like to see where is it's place.

Pictures WILL be coming SOON!

Unfortunately, i've been rather busy balancing college/exams/work/modaco/karate/sea cadets/sleep so i haven't found the time to take my hermes apart again (its a good 40 min (1 hour with photo's etc) work to disassemble/reassemble)

Will hopefully post tomorrow providing i can find a half decent camera (probably will be my c550 otherwise)

Thanks for this, just put it into action, broke my screen earlier, just took it to bits to see what its like and put it back together. Just need to find a new screen now,lol.

Worst thing is as well, i have the alignment problems, ive put it off and off, cos i know t mobile would just swap it, cant now tho, cos ive voided it :)

Edit

Saying that on the final touches of putting it back together, im left with a part, oooops lol, it just popped out when i was moving stuff, didnt see where it came from and no idea where it goes, so if you could point me in the right direction,

the part is a small black rectangle, with 2 running either underneath or on top, one end of the rectangle is a small metal piece, a semi circle in shape, doesnt look like its broken off. So any idea or tip on where that goes would be great.

Thanks

They wouldnt replace a broken screen under warranty anyway..

The only small black rectangle i can think of is the rubber microphone covering :D

Any chance you could take a photo? Might recognise it then, if not i'll take my hermes apart and find it myself and take some photos for the guide in the process.

I get this problem alot with laptops... I can strip and reassemble phones/smartphones/ppc's with hardly any trouble. When i do it with a laptop, i get a pile of 'optional bits' at the end :D Its mostly screws and small bits like that :D

Its ok, ive gone for the easy option and its going to HTC repairs on Monday.

Ive got pictures of the unidentified part, not sure how to post them tho, may have to email them to you if i can?

Also, obviously my phone is going in to be repaired, my screen is broken so i cant see anything, but ive got a few risque text messages id like to keep personal :) is there anyway of removing them from the phone, or wont they be there without my sim? Will a hard reset do it? How do i do a hard reset as i cant see what the screen says and what sounds do you get on a hard reset?

Again thanks

You could just attach them to the post here, or my email is phil*DOT*martin*AT*mail2web*DOT*com

As for getting rid of the aforementioned (love using that word) text messages, hold the two soft keys down and poke the reset hole with your stylus. then after about 3 seconds release the buttons and press R on the slidey keyboard

Hi all.

I just replaced my damaged screen with help from this thread. All was well and the screen worked fine.

Only problem is I can't get any service from my SIM card now. Everything on the phone works as it did before except I can't seem to get any signal from T-Mobile. The SIM card looks seated correctly and the pins look ok.

Is it possible I could have damaged the SIM pins or ariel during dis/re-assembly? The ariel's all enclosed in that big black thing so I'm not sure. The SIM is fine btw as I've checked it in another phone.

I did update my radio version a few weeks back, but that surely wouldn't make any difference would it? The phone doesn't revert to any previous settings or versions if the battery has been out for a while?

Any ideas or suggestions would be welcome.

Thanks, Nick.

I think it unlikely it's the aerial connection, but you could just check the gold pin is seated in it's push in gold clip. Here it is inserted:

Hi Mike,

I managed to take my Hermes apart and replace my Touchscreen. When i detached the touchscreen I had to take this orange connectors off, they were held in place with see through tape. One for the touchscreen about 1 cm wide and another one (my guess is the backlight ?!). I did so and It think maybe a bit to rough/unhandy. I replaced the Touchscreen and tried to connect those orange connectors again with some tape. Put my whole phone together again. Now I do not have backlight anymore and my touchscreen is not working... I think some pieces of the connection of the orange connectors stayed on the phone and some on the connector itself so it cannot make contact anymore...

What is the way to reconnect those orange "connectors"? Maybe it needs soldering?

On the picture you can see one of them.

On the picture you can see which connector I mean, there is another one next to that. The conntection you see on the picture is still fit, however the part where the tape was put is disconnected and I cant get it fixed I wonder how to fix it, maybe it needs soldering?

Cheers for the guides...... most useful.

One question.... I have one component which I am unable to figure out the location of.

DSC_0008.jpg

Its made from rubber and has a small slot in the right hand face as you look at the image that looks as though should accommodate some sort of lug. It also has the number "27" on it.

Anybody help ???

I'm not absolutely convinced that is the rubber cap for the microphone - although the microphone cap does fall off very easily. (It looks slightly the wrong shape to me, but I could be wrong).

You can see the rubber microphone cap here - though there is a bit of shadow around it unfortunately. It's in the centre at the extreme right side of the picture.

@dittie

Those connectors are normally just "push in" connectors. No soldering needed. You need to be sure they are WELL pushed in and straight / level. When they are in they should not be loose. The slot you push them into should grip firmly. Try to push it in evenly and firmly and try not to let it bend when you are pushing it in.

Sorry it's taken so long to reply and I hope you have got it working by now.

Mike
