[Q] HDMI output from Nexus 7 ? Is it possible at all ?

Hello, I have a Google Nexus 7 tabled and I like it very much. The only flaw I see is the screen colors but for budget tablet is is ok.
I have a question: Does Nexus 7 supports any microUSB to HDMI cable ?
I have read numerous posts in the internet about how Nexus 7 does not support neither HDMI or OTG - but I have a OTG cable and it works great, mice, keyboards, flash drives and even a 1 TB external hard drive work great on the tablet.
So I bought this cable: http://www.ebay.com/itm/2-1-5ft-1-5...912&pid=100015&prg=1085&rk=1&sd=230893786628&
but after I received it - I can't make anytong to make the cable work.
does anyone have any info on how to make it work or is is a possibility at all to have HDMI output on Nexus 7.
thanks.

As far as I know, n7 doesn't support any kind of HDMI out. As they have labeled that item as for the nexus 7 they are wrong... Correct me if I'm wrong.

Nope, sorry but there is no way. Unless no way known to me...and believe me, I made a very wide research!

[Q] Would Nexus 4 support USB OTG after updating to android 4.3 or 5 ..???

I was wondering if my nexus 4 would support USB OTG(obviously without external power bank) after upgrading to next android version 4.3 or 5 whichever comes out..
What do you people think can it be possible..????

No. It's the hardware. No software can change that.

Firmware can.
I'm not familiar with the OTG situation with the Nexus 4, but is it a literal hardware restriction/limitation making it impossible to have powered USB OTG? Or is the code just... non-existent or non-finished?

It's a hardware limitation. The phone can't detect a usb flashdrive when it's connected with a otg cable because it can't provide enough power to power the USB drive to access it's storage space.

More power can't be forced? It just seems pretty strange for a USB controller not to be able to power smaller devices like flash drives, especially with this phone (sure I could understand it with some no-name older Samsung phone, but not with the newest flagship Nexus phone).
Although I'm pretty sure this might of been discussed elsewhere in great detail.

Extra power be forced, just not from the phone itself.

Power can be forced. zidgey Kernel proves that with power you can do it. Its only a matter of programming to make the phone supply the power. All phone micro USB ports are the same, and if another phone can do it, this phone can.

is there any development going on right now to supply 5v power from the phone it self.. i've this 4 days old nexus 4 with me and its so frustrating its not supporting OTG while my old GNex did same without breaking a sweat...

Not to sound like a jerk, but did anyone click on the links I posted previously? LOL.

Writing/modifying the kernel will enable OTG but you still need a external power source to supply the flash-drive.
Zippey's kernel is modified to enable OTG.

I'm already using that on my nexus 4 and waiting for my Y cable to arrive...
BUt still i was wondering if there any way to supply that 5v from phone itself... i'm not a great developer but i think it may be possible with some programming.. sorry if i'm bothering you...

Oh no not at all. LOL. :fingers-crossed::fingers-crossed::good:
So yeah the phone just doesn't have enough power to power an OTG cable. The usb port on the phone has a certain voltage output that is simply not enough to do OTG. Boooooo

Just wondering if anyone tried to make a 3.3v-5v converter with something like the ltc3529. I saw a couple post in the arduino forums about successfully get a 3.3v arduino to supply 5v for usb host.

i dont think there is any way i could store my games on cloud... and also i own a GNex and it is capable of OTG so i never thought nexus 4 wont have that...
i bought this one just because of games and now i'm left 5 gb that means how much.. 3 games...??

It depends on the size of the game file. Hopefully the next Nexus smartphone will have OTG. :thumbup:

Android 4.3 Stock rooted nexus 4 to USB OTG
I had stock Android 4.3 and wanted to get USB OTG to have more space using powered USB.
I first downloaded and installed Nexus root toolkit 1.6.6 and Unlocked the boot loader and then rooted the phone (pre -requisites for loading ziddey-otg-r165-07291101. zip)
All went well.
I am at Android 4.3 and rooted and then I went to recovery (TWRP) and then selected Install and selected the .zip that I downloaded from XDA.
Boom!
I tried to reboot the phone and ever since stuck in the start up screen just displaying the google icon for nearly 15 minutes. Did i just manage to brick my phone? Please help!
Also I am currently using the same toolkit to re-install factory stock Nexus 4 Android 4.3
Will the ziddey-otg-r165-07291101.zip not work at android 4.3? Please help any suggestions are welcome.
Thanks,
Sandy

yup it wont... atleast for now, wait for cm 10.2 after that we may get it working on 4.3... please read the first page before flashing anything unless you want to brick your phone...:good:

with increasing popularity of 3D printers and electronics skills, it would be nice if somebody could create a low profile device that attaches to USB port and internally has a rechargable battery with DC-DC converter to scale up to 5V and has all the wiring to connect a microSD. I know I would buy it.

[Q] support for HDMI and USB OTG

im going to buy that phone but do it supposrt that? i already got hdmi and usb one from my N7000 note
wish it does(((
this phone got low storage and i really like this phone

sorry yes it doesnt have OTG support its horrible it would be awesome specially for this guy
im thinking if i get out of space

Yes it does have OTG but you need an external power.

thanks but i dont think i can find this in iran and i already got a cable for my note
anyway i dont really care about this

woops sorry! i tought its a cable is it safe:?

For HDMI out I don't think your cable will work. Majority of older phones use mhl for HDMI out but the n4 uses slimport and mhl cables will not work
Sent from my Nexus 4 using xda app-developers app

1. Nexus 4 uses Slimport, not MHL. You'd need to buy a new cable anyway.
2. OTG only works with external power, and cannot work simultaneously with Slimport (No HDMI+OTG).
3. There is Miracast, but it sucks.

damn i bough cable wanted to experience playing games on hd tv but my phone bricked after that no chance let me see if that works whit htc one s (of my father)
anyway mine got a hdmi input and a power input and a micro-usb output
and slim port is it better? never heard about it

I just got the Rocket fish Miracast dongle from best buy. Works flawlessly. Streaming Netflix, HBO, CNN, etc. For gaming not useful, but for a media center experience, is perfect.

and i will do something for storage maybe use LAN in es explorer whit my PC is there anyway suck at this to acsses or files or something using network(i mean home network)

[Q] Use a nexus 10 as a tv monitor?

http://www.ebay.com/itm/350699133529?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
I bought that for my laptop a few days ago, and thought, hey I wonder if I can use that on my tablet as a portable screen for plugging composite/s-video devices (ie my gamecube). It hasn't arrived so I thought I'd ask here.
Is it possible? I think it's either an EasyCap or a clone.
Swiped from my Nexus 10 using xda-developers app

Na, likely won't work as-is. The Nexus 10 itself would need some kind of hardcore kernel/driver modifications to make it happen; or you could bypass the N10 motherboard and go straight to the screen, which would need some kind of crazy hookup.
But pretty much, there's no easy (or known) way to make this happen :/

I found this: http://rootzwiki.com/topic/39717-kernel-module-cm-101-easycap-module/ but it's for Nexus 7. also not sure if it has the same USB ID as mentioned in that thread.. guess I'll see if I can get it to work on my linux laptop first, and then go from there.
edit: it just arrived, and the USB ID is the same [05e1:0408]. I ordered a new OTG cable for my nexus 10, my current one has been unreliable. Well I'm gonna try to get it working with my laptop now.
so I got the video to show up. however, it's not very good quality, and has serious lag. I'm going to try it on windows to see if it fixes the lag.

No DAC in Android 5

First of all I'm not the terrible newbie I appear. I logged in this site and it asked me to tie my user name with my google profile and now I'm a 2 post wonder.
Anyway I installed and rooted the Android 5 Lollipop on my Nexus 7 last night and then tried to hook a DAC to it. Previously running USBROM w Timur kernel so I know hardware is fine.
The exact same DAC's are working perfectly under Android L Developer preview on my Nexus 7 2013.
Anybody else try to hook an external USB DAC up?
Also on my USBROM set up I had a Y OTG cable for the DAC and simultaneous charging. I cannot charge through the OTG Y cable now.

I installed Lollipop 5.0 on my Nexus 7 2013 and USB DAC's work perfectly.
I was thinking maybe the root process or kernel patch broke it so I .........
So I checked the md5 checksum on the grouper Nexus 7 2012 and it was fine. I reinstalled it via fastboot and tried again before root. Negative results. No USB DAC is working on my Nexus 7 2012. When you put on headphones and plug in the OTG and DAC it will hiss for a second and then release, like it's trying to connect and then releases the device. I've tried with 2 OTG's and 4 DAC's all of which work on Nexus 7 2013 and 5.0.
Something is broken with USB DAC support on Nexus 7 2012 5.0 update, at least here on my device. Again, yesterday I had USBROM installed and it worked perfectly so I doubt it's a hardware issue.
Can someone else confirm?

yeah just tried a previously working USB sabre mini dac and no bueno.. it has a small light that lights up but nothing for sound output

Yeah, I tried it on E18. It did recognise the DAC (I know because the volume slider popped up for a moment) but there is no sound coming through through the DAC/Amp. Tried USB Audio Player Pro and it worked. Just did the latter to ensure I have the DAC properly connected. I will try it on my son's N7 2013.

I was hoping Android 5 would solve DAC compatibility issues. I noticed that Android version number can affect DAC compatibility-- for instance, the Note 2 talked to the HRT Musicstreamer 2 but not the E17 on Android 4.1.2. On Android 4.3, it's the other way around.
I would try other DACs, I think it is an issue with USB enumeration, as the hardware should compatible. If another DAC works, which I expect many will, then it will be interesting to see which devices work.

I have no less than 6 DAC's at my house and none work on Nexus 7 2012. They all work on Nexus 7 2013. Confirmed with a couple other people I know that DAC support on the 2012 isn't working. It's broken.
Actually not a big deal for me but just reporting what I found in the hopes that they'll fix it. It was one of the major bullet points of Android 5.

Thanks for clarifying.
It sure would be nice to have USB OTG + Charge and full DAC compatibility with Android 5, but at this point I am really thinking I'm over the 2012. I might pick up a 2013 because the Nexus 6 is pretty dissapointing to me.

Hi,
I'm as disappointed as U. Waiting for the updates for ages but got nothing. We've been deceived by Google's promises.
Somebody need to check the kernel first. Seems Google using old kernel which I don't know what it's capable of. Maybe no improvement on the kernel from the features PoV.
I'm monitoring with U on this thread might somebody get enlightenment

I'm sure some dev will fix it. I hope lol. Dash install in need of lollipop

In the interim I have rolled back to USBROM with Timur Kernel. It does everything. USB Audio, 3G dongle, etc.
Although it was a bit of a challenge. Every time I tried to copy the backup of USBROM from my computer to the TWRP directory it would fail saying it couldn't copy data.ext4.win back to the device. Really aggravated me I did a NANDROID backup and couldn't restore it. Then I got smart and moved the file with an adb push from computer to Nexus and then all was well again.
