I just noticed the small indentation between the microphone and the HDMI/Dock connector on the bottom of the unit. Does it have a purpose?
I've read speculation that it is where a sim card slot would have been.
Correct, it was a SIM slot.
Other variants of the generic Harmony design have a 3G/GPS module. Based on the teardown pics I'd wager that the indentation is where the door for the SIM card would go.
answered twice while I was staring at the motherboard pics up-close...
Could our little friend here be modded for said 3g or GPS modules? Cuz if this puppy had GPS, it would be as close to perfect as it could get

Hi all, bad news!
My Titan no longer recognizes the microsd card in the slot. I have used 3 different cards that work fine in a microsd->sd->USB adapter that we all got with our cards. I tried blowing into the slot (ala the NES) and that was no good.
Any ideas on what might be done? Compressed air? Disassembly is OK if there's a clear idea of what I'm trying to accomplish in there, but I don't want to take it apart without a specific task.
This phone has to last me until the Touch Pro2 comes out for CDMA/EVDO!

PS. Posted in general because it's not really specific to Titan hardware.
Are all of the contacts making contact? If so, and it still doesn't work. You are up a creek IMO.
How would I know if the contacts are making contact? They appear to work in my laptop adapter. I went down the lab and blew some (very expensive) compressed air into the slot for 30 seconds or so and tried again -- no luck.
I suppose some foreign object could be lodged in there preventing contact and resistant to being blown out but that seems unlikely...
I mean the contacts inside the phone. Those cards require metal to metal contact to make a circuit and work. I dunno how it is setup in your phone but in mine there are some flexible little metal contacts that are bent up and are pushed down by the card when it is inserted. If one of them were to lose its bend over time it would no longer push against the card. I could just use my nail or something and bend it back out so it would once again apply pressure. Like I said though, dunno how your phone makes contact.
I poked in there with a paper clip (battery disconnected!) and counted the metal tines by feel -- they seem to all be properly "deployed".
When I go into Settings-->Memory-->Storage card, it says "not installed". Does that mean card not installed or card reader not installed (e.g. a hardware fault elsewhere?)

This is exactly what happened with the NES. Every once in a blue moon you'd find one with a corroded terminal, or possibly 2 crossed. Try wiggling it (abeit more gently) just like in days of old when excitebike wouldn't play.
was watching the below linked video "hardware tour" and about halfway thru, the narrator shows a socket next to the microSDHC card, indicating it's a socket for the optional external antenna?????
the antenna socket reference is at the 2.45 mark
http://www.youtube.com/watch?v=qM0T3cBoIro&feature=related
Don't know about it being there. But there's definitely an SMA connector of some sort in the beginning of this video:

the way those components pop together, that poster that wanted to swap components from overseas models to add FFC and a flash might be onto something
doesnt the korean version of the galaxy s have tv, im sure i saw somewhere that it has and the antenna for the tv is on the right side if you have the phone facing away from you.
yeah, but the tv antenna is up at the top corner, like you said, upper right corner when screen faces away from you
this connector is next to the microSDHC card slot about 1.5" down

nothing that a piece of ribbon connector cant solve, right?
started to think you were on the mark re the ribbon cable
then was watching this video again http://www.youtube.com/watch?v=lt9XNnjAcBc - at about 1:59 it shows a larger socket on the upper edge of the black subframe -
it'd be nice if the one i suspect is an optional radio antenna socket is that after all, and meant for a cradle (like sony ericsson had) that incorporated an external antenna connection

just watched the video and its shown clearly for about 2:10 to 2:26
It is a radio antenna socket, I have on my phone to, unfortunately I don`t have a picture to show you right now.
I believe it is an external GPS antenna Socket...
Mine has it, and probably every phone has it...
this is an GPS antenna socket ... it is MMCX socket, you can find external antenna on dealextreme : http://www.dealextreme.com/details.dx/sku.14926
The internals seem to come apart very easily - they look like they are just modules with open contact bridges that just tape in place...?
Practically every phone I've ever owned included one of these external antenna jacks (FME-Female I believe), usually hiding beneath a little rubber cover. This dates back to my first, a Nokia 6190 built in 1998 which (of course) had no GPS back then. Since the GPS (at the bottom) and cellular antennas (on the top) are separate, I can't imagine this would improve GPS signals.
It's always given me a little assurance that even in the worst dead spots, I could technically snap on an inexpensive external antenna or signal booster to get a GSM connection.
For those wondering, I've confirmed the jack is, in fact, hiding under the rubber cover on the Vibrant version of the Galaxy S. Note: the rubber cover is kinda tough to pry out, but it pops back on easy enough.
Example: Cellphone Signal Booster Pack, $30
I know people might wonder why bother, but for some of you who own Renault and Peugeot vehicles in Europe, they have heat reflecting windscreens which scuppers sat-nav use in many cases hence the reason why MMC and MMCX connectors came about.
Personally, I found it easier to have a magnetic aerial and booster in the car like this
http://www.totalpda.co.uk/Carcomm/Carcomm-GPS-Re-Radiator-Antenna.7477.html
Is there any external (portable) antenna for Galaxy S when hiking on the hillside or working at a mountain area (low signal, very2 low)....?
has anyone opened this up to see if the sim hardware us underneath the little cover-up thing that was added ? i know i read online that there may be sim capabilities. when i google i don't find any results about anyone doing anything on this tablet related to a sim

well the 3rd picture down. the big white block on the right matches up to exactly where it is on my gtab but in this hardware breakdown i didn't see any explanation as to what the big white square to the right was (we have only the vertical 2d view!!)
so i couldn't tell if it's an empty spot, the top of a shell, or what
so still i don't have my answer. maybe i overlooked it in this hardware review ?
If I'm hearing you right, that's the spot for the mini pci-x slot... which is not on the board. Regardless, there is no cell radio on the board.
I wouldn't hold out hope they included a 3g modem w/o telling us about it. The easiest way would be to resolder the mini PCI express headers and plug one in, if those are actually for mini pci-x.

The open solder pads above the mini PCI-e slot, all the way at the edge, that's where the SIM socket would go.

The big white block is the SIM card slot. It's labeled on the silkscreen layer as such anyhow. The mini-pci slot connects directly so several of the connection points from the SIM headers, so I'm not sure if it would be of much use for anything other than 3G.
So two days after acheiving s-off with the new method for the s4 variant with the jb ota, my dad got the random simcard not detected error. After attempting various firmware flashes, it started getting worse to the extent that it showed the simcard icon and the x over the signal bars more often than not, so I tested his simcard in my amaze, and it worked fine. So we figured that it was a physical issue, so I read on another forum that the One X guys were fixing it by applying a layer of clear tape on the back for a tighter fit. So I had a roll of clear duct tape, applied one layer, and for a few minutes, it seemed to work. After handling the phone, the error came back, so I pulled the simcard and applied another layer of packaging tape. Now, its a tight fit, but I was careful that I was inserting it in the best possible angle so that I wouldnt damage the simcard slot. Popped it in there, played with the phone, so far so good.
Obviously this is a bandaid, but I already damaged the simcard slot by sticking a ghetto converted sim to micro simcard in, and because I cut it too narrow, it slid in kind of diagnally, and it bent some contacts, so these micro sim slots are very sensitive if not outright defective. I say this because for the past two days, I have searched google for thebproblem, and although this isnt unique to htc, there is a very high rate of simcard slot failures for the entire "One" line, including the new 'One'. I may contact htabout this, because this seems like a wide spread problem, and I already had to order a new slot, and it cost me $80 to have it soldered by the guyd at the Jacksonville,Fl branch of CPR, and as good as the technician was, it took him a second try to fix it, and weeks later, it started happening randomly, even though nobody touched the simcard. So thats the info that I have, if you have any questions regarding this issue, post it here so that everyone can see it for future referrence. Goodluck.
This post has been opened to know issues relating to sim card replacement for moto g turbo(Merlin).
I'm not sure I understand... Take out the old SIM, insert the new SIM, adjust APN or have carrier auto-provision as necessary, and go on with your day to day activities.
Do you have a specific question or issue?
Actually my first sim card slot which had 3 golden pieces one got removed, will I be ever able to use sim slot 1 again cause everyone is saying that the whole phone has to be opened. Will the phone work as before if they open the whole phone, phone moto g turbo xt1557

Oh... You mean the SIM socket or slot itself. Sorry I misunderstood the issue. I can't help there.
SIM slot (socket) repair is both difficult and risks permanent damage to the logic board. I'm no expert in it myself but I do know that there are a few eBay vendors who deal in replacement slot (socket) modules for very reasonable prices. Replacing the unit -- from everything I've read and seen on the subject -- involves some intricate work with a soldering iron. There are some YouTube instructional videos should you wish to try.
From everything I've seen through replacement parts and teardown videos, you can complete this repair without soldering anything.
That being said, it does have its risks. It does require you to do almost a complete teardown of the phone in order to get access to the main logic board to remove and replace with a new sim flex connector. They're pretty reasonable for price on ebay, and do not need to be soldered, but you'd do well to order and replace the frame sticker as well.
Keep in mind that you will no longer have the ip67 (water/dust) rating after opening your phone. (The replacement frame stickers generally don't claim to prevent water penetration.) Aside from that, the phone will function as before (provided that the repair is completed properly).
On the other hand, if the second sim is still working, and you don't need the dual sim functionality, you can always leave it as...

Ahhh. I see what you mean. This model sports the flex connector versus Moto's usual solder connected slot. I stand corrected. Good info.
