XOOM Wifi teardown - Xoom Android Development

Hey guys...
http://forum.xda-developers.com/showthread.php?t=1059781
Posting this here too.

You're much braver than I and do appreciate the pics. Because I know next to nothing regarding the internal workings of electronics, I just wish I knew what it was I was looking at.

if you compare my pics vs ifixit's, you see that the wifi xoom is missing some stuff.
now.. this could me 1 of two things:
1: the stuff missing is the cdma radio crap(likely, and who cares. ****ty tech anyway)
2: the mpcie pads are actually connected and controllable, but were missing the slot, and if a slot were to be soldered on, a mpcie card would be controllable via appropriate drivers.
now... just need to find a mpcie slot that fits....

Images 4 and 7 look like missing radio chipsets at a guess -- the "dashed line" would be where the normal shielding would be.
6 and 8 are showing the empty mini-PCIe card slot -- 8 shows what's circulated before -- there's no actual card "adapter" soldered in place, so you can't plug in a card, and also, what wyefye said regards to that.

thanks very much for the pics
you get a thanks from me

Thanks for the pics, and for posting this. However, the appropriate place for this thread is in General, where your original thread is. As such, I am closing this thread.
Thanks again for posting the teardown, though!

GPS built in?

So I just read somewhere that the our hermes have an on board gps chip built in.. any way to get it to work? or is it just there and there is no use for it? thanks

Yes you did read correctly.
The htc hermes does have a GPS
chip it's circuits, however
the chip on all release platforms have had the chip deliberately disabled in the following manor.
1.drivers removed from the roms
2. crucial pins left unconnected
3. a few support components left out
4. antenna pins and support connections for both an internal and external antenna left nonexistent .
It's very unfortunate as I spent the better part of a month looking between the thread here and on 4winmobile only to find that the best of the best hardware hackers had failed to come up with a resolve due to usually lack of tools required, components difficult at times to obtain, and the almost 98% chance of unrepairably damaging the main pcb or the surrounding components in which you would then be left with the preverbial brick of which there is no safty net or special bootloader to save you. thusly I gave up and finally just did what most get when they buy or get the hermes withco pilot. I bought a good bluetooth gps receiver and loaded software for it to be used by. in this case it was tom tom 6.
I feel for you in this one as it would have been nice if the hermes was like the artimas [ie: o2 orbit, t-mobile mda compact]
and had it built in. But alas the is no technical resolve that can be achieved as of now for this other then to go bluetooth external receiver.
*hehe chalk one up for the noobs referring to the senior vs new members to the board which I find funny as I may not post as much as others but I know more then what the rating suggests heheh*
my question is why would high paid asian techs leave some gps chip that would not be used
that is not business like at all
just like carriers leaving ot the front video camera, and still charing ridiculous prices for the unit !!!!!!!!

VGA out/ IR Camera

Does anyone know where I could find a pin configuration chart for the display cable inside the uni?
I know its adventurous but I wouldnt mind making a monitor out!

Come on people does anyone know?
Or is this gonna be a long week with the multimeter and a few books!
SD to VGA adapter maybe??
I saw in one of the Windows mobile magazines that they make SD to VGA adapters. It mentioned that there was a microSD version soon to be released, and that there was a bluetooth product as well.

If memory serves me correctly the Universal was original sold with an optional TV/VGA out cable. It may be worth posting on the HTC forum itself or digging around. I am pretty sure that it was only the first few G3 devices that were advertised as having these cables, but have had a dig around myself last year for these to no avail.

Interest information, do you know more details about that
Wow, that sounds kewl, might have to email HTC.
The only info I could find on this is whats in the Wiki anyways
The touch-screen controller given shows the pin-outs which should tell us the touch-screen pin-config'.
I've given up on this anyway so I turned my camera into a nightvision camera really easy to do!

Share more details, I too was playing before with camera and IR leds
sorry this will be mega rushed just realised im still in my pjs and gotta be at work soon!
Basically you dissasemble to PDA as shown in the wiki, then take apart camera base, behind it there should be a coloured filter (IR filter) take it out and replace with two really dark things (like the begining of a negative) then put together and take pictures in the dark whilst pushing a button on a remote control i will make a proper how to do thingy when im home tonight!
Bye for now!
IR Camera
Right first of all I think I tried it with my Uni and couldn't suss how to get to the IR filter but I tried it on my Nokia and its working like a charm!
1: Take apart the phone,
2: Uncouple camera,
3: Using a knife prise the four corners of the circuit board off the base of the camera (make sure you only go about 1mm in MAX! Also make sure you remember which way round it goes ),
4: Unscrew the lenses off the front,
5: Punch out the IR filter, this should be the slightly coloured one usually red (or find a way to take it out properly if you wanna keep it but mine was glued on),
6: Find an old photo album and take the negatives, look for the first part where it is just pure black (no pictures) and cut two circles out of it to place where the IR filter was, (this will be your visable light filter),
7: Reassemble,
8: Go somewhere dark and use a remote control as a light source and take photos!

yea i read it too...oh wait i think i remember where i read it....in the development n hacking section....they talked bout it...i think u can still buy those optional TV/VGA but the only problem is that u cant use the sd therefore u have to use the main memory which is not enough...

[Q] Use Gnex as ID card

I want to know if its possible to read my contactless work ID card with my phone and then use the phone as my ID by tapping it to the reader.
I don't know if this is even possible and my question isnt about the Nexus as much as it is about My ID card, but if anyone can help me figure out what kind of ID card I have and how that would or wouldnt work with the hardware in the Nexus, I'd appreciate it.
Thanks.
There is some sort of chip in your ID or is just a bar code you're trying to scan?

Some sort of chip. I tap the card to the reader in the elevator and at the front door to the office.
I don't even need to tap the card directly, I keep the card in my wallet and tap my wallet to the reader and it picks it up fine.
Let me know if I can provide any more info.
Thanks
I can't think of anyway to extract the information from the chip, but you could always cut the chip out and tape it inside the battery door. I wouldn't think anything would interfere with the chip, but I guess would might need to have an undamaged ID card.

Yeah, that wouldn't work, it doubles as a picture ID as well so I would need to keep it undamaged.
I've seen apps that read and store data when tapped with a credit card, so I was hoping someone would be able to provide similar info for how to do it with an ID card. I don't know enough about the different NFC and RFID technologies and what the nexus is capable of. Was hoping someone on here might be able to help.
Check out this thread from a few months ago. People came to the conclusion that it isn't possible.

From what I understand, data that's on most RFID cards is encrypted and the NFC antenna on the Galaxy Nexus (and Nexus S) is not currently capable of interpreting the data. It certainly seems that the possibility is there though seeing as how they usually operate on the 13.56 MHz frequency.

I posted this on another thread, but I think it is worth it here also. HID is beta testing using NFC technology for card access with Blackberry devices. Youtube HID Global Pilot Arizona State. NFC uses 13.56Mhz frequency. The HID iClass readers should work ONCE HID gives the customer the ability to get the software used to tether the phone to your computer and connect to the "secure" part of the Android OS and create a credential. It is coming. Just waiting on HID Global to make it happen.

Cracking Open the HTC One X ?

Does anyone one know if anyone has done one of those "cracking open" vids for the HOX yet ? I would be interested to see how it's set up inside. I'd also like to know if the 32GB internal memory is actually a micro-SD card that could be swapped for a 64GB at some point

I would be shocked if the internal memory was a MicroSD and not soldered to the board. It kind of defeats the purpose to make it non-removable and NOT give us the performance of a dedicated connection.

Shocked or not, it's what they did with the HD7. I wouldn't be surprised at all. A good, high speed SD card?...you'd never know the difference
Whatever is the cheaper option. That is what they did. Can pretty much guarantee it.

From a diagnostics, servicing & repair point of view it would be much cheaper and easier if it was an SD card.
Not sure about manufacturing. Probably about even.
Just wondering if the only way to open up the One X is to remove the LCD screen? If yes then what's the point of knowing if it's a 32mb SD card? Is the average joe able to open it up anyway?

Is there a doctor among us?
Put a HOX under X-ray (Turn it OFF first) and post a pic here.
We'll find out, if there is a memory card or something. Also, may be we'll see how to disassemble a HOX.
I think the HOX may be easier to disassemble that you might think.
I bought a gel skin case for mine which I take off fairly often because the HOX is so damn beautiful and nice to hold that it seems a crime to ruin it with a case.
Anyway, the case it quite a snug fit and I noticed when removing it that if I put my thumb on top of the polycarbonate just under the buttons at the bottom of the screen and firmly but gently flex it back I can snap the polycarbonate away from the screen by just a few millimetres. I can clearly see three little snaptabs sticking off the bottom of the screen that hold the polycarbonate in place. It snaps right back into place immediately.
I am too scared to try this right now but I think with further gentle pressure the whole outer casing would be levered away and you could lift all the innards out of the polycarbonate unibody.
There is clearly no "tool" access to the device so I assume that this is how it is assembled and disassembled.
BTW, here is a short video of the "opening" I mentioned above :

Maybe someone who's already bricked theirs or got a DOA.
Mine's too new and shiny
So maybe this brings hope, that this is not a throw away phone or a send back to HTC service centre senario. Hopefully the battery could be user replacable in a few years time, once third party batteries become available.
gives me hope too...
even if it's a Li-Po, probably third parties will make a bigger battery for it, if it's possible.. >=)

Harrier and Blue Angel - twins or cousins?

As we′ve lately discussed the question if HR has got a built-in wifi-device similar to BA I'm starting this thread in close connection to D-Two's Android for Blue Angel-Thread. Hoping to have some Harrier at hand pretty soon, built-in parts will be listed.
Right from the start my thanks go to GnatGoSplat!
:highfive:
I saw in your other thread about adding an external bluetooth into a BA. That's yet another difference, Harrier has built-in GPS.

Can you say which GPS chip?
EDIT: ok i think this chip is the real different!!
datasheet this chip is for GPS and CDMA...
I haven't taken it apart to see the chip, but yes, I think it does have an MSM5500 inside from what I could find on Google, and that chip does have the GPS and CDMA included so I'm sure that must be it.

ok, so we need for the harrier a linux driver for the chip and the harrier is fully work :victory:
Does Linux/Android treat the MSM5500 like a modem? I have seen references to Linux drivers for USB modems that use the MSM5500 chip.
Like this: http://www.ka9q.net/5220.html
Although I don't know anything about Linux so I don't know if any info there is useful.

And Harrier has its backup-battery where BA has its wifi-antenna.

O.K.- scanning had been a stupid idea- those modern machines don't give a sharp&deep enough pic.
Now made several photos of unshielded BA & Harrier mainboard. Will upload tomorrow.
For first two pics, didn't have good light yesterday evening.
Interesting: Harriers' GPS-antenna is placed where BA has bluetooth; harriers' bluetooth is next to IR.
The area under black foil is for simcard-holder.
Flashlight of harrier can't be built in BA, has got two spiral contacts on motherboard.
The board layout is surprisingly different for looking so similar on the outside.
Are any parts the same and interchangeable? LCD maybe?

At the cam you see top right two brass squares- are the contacts of flashlight conjuncting to the spiral ones on the mainboard.
Will compare BA and HA cam, and IF they should be different mount HA cam in BA to test if it works.
