[HACK] Hardware HDMI/MicroSD Hack? Unused Pins/Connectors

HI! i've found some pics of the nexus 7 motherboard and some connectors seems to be unused... If you look at the "con1" (the one used for micro usb connection) it has 22 pins 0_o. Maybe we can find a hardware hack =D
More images here
We could do a "simple" (dangerous) test: HDMI has a hot plug detection pin, the only way to check is provide one pin with +5v dc and check if any other pin sends a ddc query.... but how can we find the hotplug pin (if there's any)?

From the teardown it was pretty clear there was space for the rear camera as well as HDMI.
The IO presenters were using units with HDMI, so it was probably the same motherboard, populated.
You would have to be a hard-core hacker to want toi add your own HDMI. No idea what is missing beside header and connector. Probably not as bad as adding MHL
I am happy living without HDMI.

Maybe I will never use the hdmi connector but hacking electronical things when i have to hack biological ones every day is a nice way to spend the time xD

Can't back it up right now but will frantically google to find it.. But I remember reading that it had the hardware for mhl but currently not enable in software?
but just tested my jellybeaned gnex and that works fine with mhl so not sure how much truth there is to that.

I can vouch for the photo of a Nexus 7 with an HDMI port, as well as a comment from a presenter that the special units they were using for presentations had HDMI.
No, I can not provide any links. That was thousands of pages ago...
I do not believe the Nexus 7 has the MHL chip, or any provision for it. Asus is not listed as a MHL provider.
Samsung (Nexus) is a MHL provider, so the hardware there would not be a surprise.

In that teardown review (where the OP got that image, I believe), they mistakenly said it supported HDMI out and included a picture of the HDMI cable from the nexus Q. They later retracted that comment.
That might be the source of the confusion.

There was at least one actual picture of a Nexus 7 with an HDMI port on the bottom.
I think a reviewer got their hands on a presenter's unit.

The image you're looking for is in this thread:
http://forum.xda-developers.com/showthread.php?t=1736916
The internel dev versions (the ones used for presentations) had mini hdmi.
So, it does make sense that theres space on the board.

Thank you for that picture link! I searched everywhere for that...
At least that is one less reason to think I have lost my mind...

I'd love to be able to solder on an sdcard slot, if that's all that's needed. It's generally pretty easy to solder to headers if you're careful about it.

From the teardown, I don't recall seeing any space for an SD card.
Rear camera - yes, HDMI - yes, but not SD Card.
I could be mistaken...
Also, the external storage problem has been pretty much solved with a USB OTG cable and stickmount.

we could solder a slod for an additional sd card... there's enaught space to fit in a sd card without "external" access.

we're counting pins and waiting for more info =P
look here: http://guide-images.ifixit.net/igi/KjNsrjlvHZdFWEGF.huge
we have 14 free pins and an hdmi data connection requires only 12 wires + 5v + grnd.
i'm looking for someone who can do some simple tests on the unused pins.
when i will have the nexus 7 i'll do it by myself at uni but maybe someone who have the I/O version now could do something meantime.

Looks pretty interesting to me hope we cram a sd card In there somewhere.

With the dock we have one station for video playback on TV, but together with option to control remote the phone with mouse and keyboard.
A very useful feature which makes us independent of the length and number of cables for this hardware and control the device.

If that's true that would be a great addition, BUT I haven't read anywhere that that would be an option for the tv dock. The micro usb is solely for charging purposes because mhl is dependent on external power supply.
I can however hook a keyboard/mouse to my tv itself. And also the tv remote is able to control your phone.

Then LG produces hdmi protocol incompliant TVs which I somehow doubt they do, as a major player in the consumer electronics and tv market. I'd rather say youre not using a correct cable rather than LG not having implemented hdmi cec in their devices.

Yes, in my TV missing option for cec control. That is.
After a thorough examination of the photos of the station, i saw no usb connector and missing supports on this for remote control devices .
In this situation I would not buy this product.
Where is the logic in this? Old dock have this options, but new dock don't have this.
How we will make remote control on this phone Xperia T with new dock or other product, if ours tv doesn't have this support for remote control/CEC/?
What is the way?

The dock must have a usb port (or power connector otherwise) as MHL needs an external power source.
The dock supports standard CEC/remote control, if your TV doesnt offer it, youre out of luck. Nothing sony or any other manufacturer could do about that. Your TV is ****, buy a new TV, basically.

[BUG] USB OTG - could we get some N4 community members to help raise this issue

Hey, I purchased a 16GB model, with the intent of using USB OTG to use in conjunction with USB flash drives like we can with basically all other phones these days - but obviously it's still my fault for purchasing on the first day without knowing that USB OTG isn't supported on the Nexus 4.
Now that it's pretty much all but confirmed that USB OTG isn't working on Mako, maybe we could star the 'bug' on the official android bug report website, and maybe at a comment to voice opinions that some of you (as well as me).
If we all star it & maybe add a comment, it could help?
http://code.google.com/p/android/is...s Owner Summary Stars&groupby=&sort=&id=40087

Please don't add a comment. As noted in that thread, adding a comment spams everyone who has previously commented or starred. If you have something new to add, fine, but if you're just posting "Yeah, this stinks!" or the equivalent, please refrain.
(Anyhow, I'm not sure how much that bug report will help; it seems most likely that the hardware just doesn't support USB host mode.)

I'm holding out hope that it's a software issue at this time until it's confirmed by Google. I know they wrote Mako can't supply 5V but even with a powered USB hub devices don't work.

I'm not entirely sure this is a bug. It may be a design choice combined with poor documentation.
Look here:
http://support.google.com/nexus/bin/answer.py?hl=en&answer=2809827&topic=2809758&ctx=topic
This page clearly says "USB is not supported for connecting such devices."
It appears to me that USB OTG is not supported on the nexus 4.
We can keep our fingers crossed that this is fixable via a software/firmware update. Although I'm concerned that that USB OTG is hardware incompatible with the Slimport display solution LG has chosen. Both USB OTG and slimport display use the micro USB connector's pin #4 for different purposes. USB OTG needs a cable that pulls it to ground to indicate to the phone that it should operate in USB host mode. I'm less familiar with slimport, but from what I've read it seems to perform some signaling on pin 4 to enable and stream video.
If the two really are mutually exclusive, I personally wish they had ditched slimport in favor of USB OTG since I can (eventually) mirror the display using miracast.

They just updated that page today (dec 6 depending where you are). So it clearly says that... only after the phone has been out 3 weeks until today the documentation said it should work. they basically just said "yes it works" and then a month later said "lol jk no it doesnt"

If you're holding out hope, I appreciate your optimism but it probably isn't going to happen... I'm considering calling up Play support and asking for a refund so I can get a 16gb, even though that probably won't happen for a few weeks,
BTW... just called the play store. They will NOT return your device because of this issue. Even for an exchange (I just wanted a 16gb) I don't understand their logic but because they changed their documentation, I guess that removes them of liability... IMO that does nothing of the source. I'm filing a BBB report now, which is something I never thought I'd do to google... this is BS.

Class action is probably the best way to handle this. I'd much rather have USB host mode.
I voided my warranty.

I bought the Nexus 4 under the assumption that I could at least get USB OTG to satisfy the lack of a micro SD card. FML.

Call again and talk to someone else, as long as you are within the return window, you can return for any reason at all, with a restocking fee.
Or you could scalp it on ebay to and make money on the whole deal :shrug: I'm just glad I didn't know about OTG when I purchased it, or I would have gone 8GB.

Aftermarket Dock (using POGO). Would you Kickstart?

So I am usually a lurker on XDA, but I thought I'd get the community's thoughts. I'm a fellow Nexus 7 owner and I want a dock that uses the pogo pins. I'm tired of waiting for ASUS and I also happen to be a mechanical engineer that works in the consumer electronics industry. So, I've mocked up my own design. It's similar to the ASUS design and will have USB charging and audio out. The only way I could bring it to market is Kickstarter.
Before I go through that much effort (Kickstarter has revised its approval process) I want to gauge demand. The sale price would be $30. I've made a poll below to streamline things, but feel free to add comments. Rendered concept below. I am also considering adding stereo RCA outputs as well. Would you want that?

|UPDATE 1|
Thanks everyone for the feedback! I'm still in the early design phase so feedback helps. To address the request for speakers: at this point it's not something I'm looking to add. It adds cost, development time and complexity. Depending on how well things go if I put it on Kickstarter, a speaker option may be considered. Also, now that I've seen there is some interest, I refined the design slightly to slim it up. See below:

I would love to, but the pogo pins do not support USB OTG (needed for keyboards, usb drives, etc.) That would require connecting to the micro-USB port. Also, as of now, charging while using OTG is almost non-functional. It may be possible with the Nexus 10 (6 pin pogo) but not the 7.

Hi developers, I'm thinking about buying this phone but I have some questions to you who own a MHL HDMI adapter for Xperia Z1.
1) The phone uses MHL 1.0 or 2.0 ?
2) At what frequency works the HDMI ? 30Hz or 60Hz ?
3) is the output to TV laggy / delayed ? if yes, how much? (screen from my SGS 2 is delayed by about 500ms what I feel acceptable for movies/surfing but bad for work)
Thank you very much for answers.

I used 2 different MHL adapters. One was from Rocket Fish and the other was just a generic type MHL Adapter which just had MHL apapter written on it. The Rocket Fish one was $9.99 and the generic no brand one was $24.99 . The Rocket Fish one performed slightly better. I played Rayman games on MHL to my Sony 60" LED HDTV and it was flawless no lag, tried Asphalt 8 and was great, tried Modern Combat 4 and I had major lag, slowness to it. Web browsing and playing around the interface was good, you can tell it has a slight lag but I think it was great really.
I think theres an option in the developer options to display the 2nd display to 720P and Im sure that would improve speed a bit.
Go for the Rocket Fish MHL adapter. It worked great for me except for the very intensive game Modern Combat 4.

The original stock adapter it's always a good choice to make it work right.

I just checked some of the response from that youtube video and the creator of that video did say it won't work with Xperia z1. Thats weird because I thought the Galaxy S3 also had a 5 pin (1.0) MHL and it worked. I am wondering why it won't work with the xperia z1 that is also 5 micro usb. I already ordered a Samsung MHL 2.0 from my local NCIX. I should have it in the next few days. I will report back.

i think it's a global problem... hdmi 1 or 2 or whatever just means if hdmi will work or won't.
once it's working it should run the same on every adapter...
untill i see a video of z1 working flawlessly with a specific hdmi adapter i'm not convinced.

This piece of crap can't even output 1080p. I went to the service menu using *#*#test#*#* (replace test with corresponding numbers) and there was select resolution option. Of course it said N/A even though I had the ability to choose the resolution which didn't change anything.
I could tell a small lag in GTA San Andreas + Sometimes it even lagged (for an eye-blind, but still) in the plain UI doing nothing. I also tried DTS and Dolby Digital plus. Both worked in stereo.
Weird thing is that even though I was doing basic stuff like chrome etc it didn't charge using the stock charger and cable if connected to this adapter. HDMI cable was not plugged to the adapter at all. I tried to use it as a charger pass through. With HDMI not plugged in the phone said smartconnect: charger so it's the adapter itself.
Stay away from this one for sure!
Will try this rocket sth one.

I won't get it until after the weekend, but I will remember you guys are waiting

I bought a cheapo eBay version, from here: http://www.ebay.com/itm/1080P-Mini-Micro-USB-MHL-to-HDMI-Adapter-Cable-150mm-NEW-/200912649225
Lag is non-existent, or at least not easily noticeable, when scrolling through screens or websites. I haven't tried playing games but I don't see a problem. Have heard a lot of problems with these adapters, but I lucked out and mine works with no issues.
The specs for even MHL 1.0 say that it supports 60hz 1080p; in fact the only difference I could find in v2.0 was 900mAh charging, versus 500mAh in v1.0, and some kind of Samsung compatibility improvement. Samsung uses 11-pin microUSB port, and requires a specific USB-MHL adapter (or a tip adapter, 5-to-11 pin).
