Well, I have a Milestone 2 (A953) with a quite beaten body, and a better-looking Milestone (A853). I took out the guts of the M2, and swapped them in the A853 body. Everything works ok, aside from the power/volume/camera flexible cable, which is quite beaten, and the physical keyboard and front keys, due to the differing layouts...
]Do you guys know if simply swapping the qwerty.kl and other *.kl files between boards would fix that? Didn't do that yet, fearing a brick where keys don't work.
Also, any tips on fixing the tiny metal domes that make up the volume switches? Mine were broken, pulled new metal discs from a dead SE u20i, but they get loose easily, and I found it quite hard to tape them back into place, so the volume buttons feel mushy instead of clicky, quite unusable.
TIA

don´t switch the kl files - modify them. You have to take theese two files: system/usr/keychars/sholes-keypad.kcm and system/usr/keylayout/sholes-keypad.kl

I think that custom recoveries have keyboard tests, those should output the numbers corresponding to each button you press, that should help you when building a new keypad layout config.
Good luck
Ok, thanks for the replies. Will find a way to get the keycodes. For now, I'm hosed, no RSD/Recovery due to broken volume buttons, will get to fixing keylayouts after I fix those.

The "a" on my keyboard was getting flakey. It took a couple times of hitting it to work, and I was really getting annoyed. Also after almost 2 years of using this HTC (Branded the 8125) by Cingular, I was itching to disassemble it.
I could not find any information on repairing the keyboard/key cleaning.
There is a manual for this in the ftp space should anyone need. It is not specifically for the Wizard. You have to prise the lower housing off in a similar fashion. The rest of the disassembly is easy enough. Soon, you will have the 'middle' section of the phone in your hands, with only the keyboard and its flex connector attached.
Look carefully for screws, tabs, clips, anything that is holding the keyboard into the piece. You won't find one. Look even closer, and you still won't. I had my glasses off (contacts out) and focus at about 2" and still didn't see a damn thing holding the keyboard assembly into the part.
That is because there isn't anything.
I apologise for not taking pictures, it was together before I remembered. But here is the issue:
If you look at the bottom of the panel that holds the assembly, where the softkey buttons are, there are slots that allow you to see the layers of the keyboard. Using a very fine x-acto blade or knife, slide just under the black layer, and pry up. The keys and their laminated components are glued down to the flexible board that has the key contacts. The 'domed' part of the contacts is part of the key layer, and will be the bottom. A bit of cleaning and the contacts were again happy and shiny.
Make sure that when you put the key layer back down that it is centered properly. Make sure that the soft keys at the top are not bound, or they will stick up and catch the slider.
Oh, and the kicker? None of the other disassembly was needed, since there was nothing inside the phone to release the keyboard. But what the Hell, it needed a good cleaning anyway.
One more thing, the best place to do this is NOT in a hotel room with almost no tools. That makes it far more challenging.
Hi all, my Trinity's hardware buttons doesn't work.
The 2 softkey hardware buttons, the red and the green button, the ok button and the Start button seems to be broken also if they have backlight. All the others buttons are ok.
I've tried to softreset, hardreset and flash the ROM (I'm using last Ervius ROM). After flashing for the first time the buttons were ok for a littewhile but now they seems to be broken again even after several flash. I've also tried to downgrade to wm5 but nothing change. I think that is an hardware issue and I'm going to try to fix it by opening my Trinity hoping that is just a flat connector pluged out but if someone else has experienced the same problem and has to suggest me something is really welcome.

I experienced this myself, and replaced this item:

keys are stuck
Mine also, but solved it after a couple of days (temporarily). The hardware buttons problem seems to be related with one of the keys stuck. If one of those keys is stuck none of the others work. I tried "fast" double clicking on one key at a time to unstuck and it worked for me. Mine has been working for two weeks with no problem. Anyway I ordered that part "just in case".
So before opening your trinity try to unstuck the keys. It seems to be related with humidity conditions and carrying the phone in the pocket (just a guess).

I'm going to try this becouse during the last 4 days sometimes the buttons work so.... thanks!
Ok, nothing work.
I've also tried to open the device but looking behind the buttons pad fortunally/unfortunally there isn't an evident hardware problem.
The only solution is to replace the pad.
Hi to all.
I have had buttons not working on my trinity for some time. was tempted to send it back for repair but i did not want to be without my phone and did not want to have to stick the old wm5 rom back on!!
I took my trinity apart too see if i could see anything wrong. and got it down to the keypad. one thing i did notice is that there was a lot of dust. also around the small disks that provide the buttons, there are 3 small holes in the sealing sheet. seems that the construction of the switch array is circuit board at the bottom, with small tin disks on top, all held in place with a thin plastic sheet.
The tin disks 'pop' inside out when you press the buttons, making the contact for the switch. On the old nokia phones, these disks got deformed and this would make the button work but with no click. I had a click but no button operation, and with the holes, and all the dust i found, i figured that it must be dusty contacts.
so here is how i managed to fix my buttons for free:
1, strip the phone to get to the keyboard circuit (i used this link clicky)
2, clean all the dust from the buttons
3, start to tease the plastic film from the front of the board (i used a sharp knife but mind your fingers and take care not to damage the board)
4, once one corner is up you should be able to slowly pull the film up (take care not to damage the disks as the plastic comes up but make sure the disks stay on the plastic sheet)
5, dont pull the sheet totally off otherwise you will have a job getting it all to line up after.
6, get some alcohol or head cleaning fluid on a cotton bud and clean all the gold contacts, as well as the insides of the discs.
7, slowly rub the plastic film to put it back where it came from, taking care to get the disks in the center of the gold contacts.
8, rebuild and test
All being well you should have working buttons again!!! It seems the design of the buttons lets dust inside the workings.
Hope this helps someone with clicking buttons but no action!!!

Hi, seems I'm asking for a bit of help lately
Anyway on my qwerty keypad the letters U and O have to be pressed harder than all the others otherwise they won't register, I mean hard enough to slow down my typing quite a bit. I have pulled the phone apart many times and played with the keyboard position, put bits of paper in between the membrane and pop buttons etc.
When I first opened it up I noticed that the keyboard PCB was sitting above the hook looking piece of plastic holding it down and the board had been ever so slightly warped from this, I have since rectified this but the keys still need pressing hard.
Any ideas? Anyone with a similar problem?
EDIT: This is the Hermes I got from ebay second hand BTW.

Hi Guys,
so I noticed over time that a couple keys weren't working on my dream's keyboard sometimes, and it became progressively worse up to the point where said keys stopped working altogether. The Affected keys are: 1, 2, W, S, Z, Left ALT, Volume Up. If you have a look at your keyboard, you will notice they are in a line almost, which led me to think there was a problem on the Keyboard PCB, or it's ribbon connector to the Motherboard.
SO...I bought one of these Ebay PCB replacements: http://cgi.ebay.com/T-MOBILE-G1-HTC-DREAM-KEYBOARD-MEMBRANE-KEYPAD-PCB-FIX-/120690721519?pt=PDA_Accessories&hash=item1c19ba42ef and just fitted today but, and to my disappointment and dismay, the exact same keys still do not work
I have cleaned the internals using compressed air quite thoroughly and still not winning.
Any ideas as to what the real problem is here? Maybe its the motherboard itself?
THANKS!
I have a problem with my right alt and . Key as well, hope we can solve this

It is not particularly clear what that item is. Is it a complete keyboard? PCB? Just the rubber membrane?
The key is to CLEAN the thing. 99.9% of keyboard problems are because there is dirt somewhere. Rubbing alcohol and a mild abrasive (like a pink rubber pencil eraser) are very useful for cleaning.
Its everything you see in the picture, keyboard pcb (which has the actual buttons which are pressed when you press the plastic button above, and the volume buttons), with ribbon cables, metal part that sits behind the keyboard - (it is not a replacement for the buttons on the rubber strip which overlays the keyboards hardware)
I stripped the phone completely and replaced the entire keyboard pcb, and still the same issue... i don't understand how cleaning would have made a difference on a brand new item... where else do you recommend i clean?
I'm hoping somebody with some knowledge of the HD2's innards can help me...
My vibration stopped working on my HD2. I found the plastic LED flash cover to be 'pushed in' (with the help of a couple xda threads I dug up). Others said it was an easy fix: Open the case and push that piece of plastic back into place.
I opened up the case to correct it. But after putting it back together not only does vibrate not work, but the volume keys, speakers (both earpiece and speakerphone), flash, notification led, and camera all don't work.
I obviously screwed something up, but I have no clue what it could have been. I was very careful. One thing I'll note is that when I pulled the case apart, the plastic volume rocker went flying. When putting the phone back together I got it back into place so that I THOUGHT it should work (it was seated properly and felt "clicky" for up/down movements.
But clearly wasn't just the volume rocker that was affected. It doesn't seem that I pulled anything else loose or anything like that...
But no luck, all that I listed above is non functional, and what I'm left with is a glorified 3.5 in tablet
Any ideas?? Thanks in advance!!!
Snapped a couple quick pics which may help:
http://i50.tinypic.com/mmsa36.jpg
http://i47.tinypic.com/sl1kdx.jpg
Unfortunately when comparing these to other pictures of the inside of the HD2 that I found online, I fail to see any differences, or anything I could have inadvertently screwed up.
Most likely you screwed up(or disconnected from motherboard) somehow your main flexboard, but your picture are not usable for this, you should take off your motherboard+main flexboard from chassis to have a full view!
You probobly just disconnected a small cable. I have no idea of the HD2 innards but did multiple repairs of small stuffs and the flat cables hold in place by a plastic clicker pull out easily - just reopen and check them all, you should be fine.
Thanks for the input! I figured it's something like that, just one small cable. But I didn't even take off the board at all... The pictures show the full extent of the disassembly... Do we still think it's necessary to disassemble it further?
I checked all visible connections, but yeah, maybe I somehow yanked out something that is NOT visible. I'll try to check again today... In the meantime, any more ideas from anyone else? Thanks!
For al that to be not responding I would assume main-flex damaged or as mention before maybe connection to mainboard got moved during pulling cover !
Volume button can be troublesome, sometimes the little plastic caps come off but if it felt clicky should be good in that respect.
also be very carefull of thin spring metal legs that contact antenna pads on back cover, one near screw above & right of vibro motor looks a to be a bit flat. They bend easily & break easily too ...
Have u tried starting up the phone without the backing? I had this issue when I painted my housing the led cover was stopping the motor from spinning but if i took out the backing it works. So I just trimmed the led cover and now it works.

I'm nooby with regard to this stuff; I only attempted the repair since I read in a couple other threads about multiple self-proclaimed non-super-tech savvy people were able to open it up and move the plastic LED cover for an easy fix.
So what exactly am I looking for with regard to the main-flex? Where is it? I thought I wouldn't really see that unless I removed the board which I haven't done... is it still possible I knocked it loose or damaged it? I didn't think that would be possible since I ONLY removed the back cover (though it does take a slightly uncomfortable amount of force to do so, so I guess anything can happen...).
If not the main flex cable, is there anything else specific to look at which may be disconnected? It seems to be all the stuff at the top of the phone that fails to work (camera, speakers, vibration, flash, volume keys). While the stuff on the bottom (other hardware buttons, charging jack, headphone jack, etc).
THanks!
I have given up. After being stumped briefly how to hard reset the device without the volume keys working (I have Android installed), I was able to do it via ADB from the Android dev kit.
To ebay I go...
