Hi there just joined this wonderful forum and basically i am an Andriod noob :victory: I am very late to the party and never owned a smartphone or andriod device but with people going for the 2013 Nexus 7 and offloading their 2012 models at a basement bargain price i finally decided to jump on the Andriod bandwagon
Ok here's the thing : i bought a 2012 wifi only Nexus 7 and the seller stated that it has been rooted. I have a Fiio E7 USD DAC that i am using at home with my desktop and with the laptop @ the office. From what i read with some tweaks a Nexus 7 works fine with this particular USB DAC. Thing is i have downloaded apps like games, ebook reader, FLAC player, etc and more importantly files. From what i understand i have to "flash" to a new kernel that is USB DAC friendly? Could someone dumb it down so i could understand what exactly i should do to achieve this? Would all my files be lost if i flash to a new kernel? Thanks in advance ya

Hi, hodak...
Much of your post doesn't mean much to me I afraid... although I do remember reading years ago, that DAC stands for Digital-to-Analog Converter and FLAC stands for Full Lossless Audio Codec (I think)... but that's about the limit of my knowledge concerning technical digital audio related stuff.
With regard to "flash to a new kernel that is USB DAC friendly". I have no idea if such a kernel exists. But if one does exist, it will almost certainly be in .ZIP format (which, by the way, you don't unzip), and would be flashed via a Custom Recovery.
There are two such Custom Recoveries available; ClockWorkMod Recovery (CWM) and The Windows Recovery Project (TWRP). They both do pretty much the same thing... with such a Recovery, you can flash Custom Kernels, Custom ROMs, root your device, and perform Nandroid backups (which are 'carbon copies' of your Nexus 7's state at the time the backup was made... even right down to the last app icon or widget you last dropped onto one of the home screens). Nandroid backups are extremely useful for returning your device back to it's last working state, in the event of a ROM (or kernel) flash gone wrong.
If you've never used a Custom Recovery before, you're probably wondering which one is 'best'. Well, the answer is a rather unhelpful 'neither' . Like most things Android related, it's very much a matter of personal taste. CWM has been around for years, and is favoured (mostly) by Android old timers. TWRP is the new-kid-on-the block, so to speak, and has a more intuitive interface than CWM, so I guess I would recommend TWRP as this is your first foray into Custom Recovery related stuff. Anyway here are the download links...
(It's important you get the right version for your device, so if you have a WiFi only Nexus 7 (as you do), you're going to need the 'grouper' Custom Recovery...and 'tilapia' Custom Recovery, if your Nexus 7 is both WiFi and 3G capable. Download the correct one to your PC.
TWRP for 'grouper'
CWM for both 'grouper' and 'tilapia'
But before you can fastboot flash a Custom Recovery, you must first unlock the bootloader on your Nexus 7 (and this is the bit you're not going to like so much)... unlocking the bootloader, performs a full wipe akin to a factory reset. So before proceeding you must first back up everything that is important to you on your Nexus 7 to your PC or some other external location.
However, none of this might be necessary!.
In your post you say "...and the seller stated that it has been rooted.".
Unless the seller rooted the device via the motochopper 'exploit' then there's a very good chance the bootloader is already unlocked... which means you won't loose your stuff. If there is an unlocked padlock symbol at the bottom of the screen, underneath the Google logo at boot... it means the bootloader is already unlocked.
So, to summarize...
* Backup your Nexus 7. (Might not be necessary if the bootloader is already unlocked).
* Unlock the bootloader with fastboot oem unlock (Might not be necessary...).
* Fastboot flash a Custom Recovery with fastboot flash recovery custom_recovery_filename.img
* Using that Recovery, flash your Custom Kernel.
* Restore your stuff back to your Nexus 7. (Might not be necessary...).
To reiterate... if the bootloader is already unlocked, then only the third and fourth steps listed above are necessary.
The full details of how to use fastboot and a link to the necessary drivers are available here. It looks more complicated than it actually is... but that's only because Comminus (the OP of the thread) is thorough in his explanation, and covers a lot of ground.
--------------------------------------------------
One other possibility occurs to me... If you're already rooted, you can use either one of these two apps...
Flash Image GUI or Flashify.
...you can use one of these two apps, to flash a Custom Recovery DIRECTLY FROM THE NEXUS 7 itself, without recourse to a PC or the need for fastboot. Just download the Custom Recovery .img file from one of the links above, directly to your Nexus 7... and then use either Flash Image GUI or Flashify to flash it.
Once you have CWM or TWRP installed, you can then download, directly your Nexus 7, the Custom Kernel of your choice... boot into CWM or TWRP and flash it.
How to boot into your Custom Recovery
Shut down the Nexus 7 completely. Press and hold VOL-DOWN... whilst holding, press POWER ON (hold both for about 5 seconds). This will boot the device into the bootloader. Using the VOL-BUTTONS, navigate to the RECOVERY MODE option, and press POWER ON to select. Your Nexus 7 should now boot into your previously installed Custom Recovery... CWM or TWRP.
--------------------------------------------------
And that's the Cliff Notes/Reader Digest version of how to flash a Custom Kernel. All you have to do now is find one that fits your digital audio requirements... and that, I'm afraid, I can't help you with... unfortunately.
Hope this helps... and good luck.
Rgrds,
Ged.
I think this rom might work for you
"USB audio kernel driver enabled
USB audio plug&play patches for DAC plugged at boot"
"USB audio plug&play handler for DAC plugged post boot"
"Supported USB audio devices
These are just some of the supported USB DAC's: CM106-F, FiiO E07 + E10 + E17......."

I won't iterate what's been said, just add a few things you may find useful.
In addition to a kernel that support USB Audio (here's the one I use), you'll also need an OTG cable (On The Go). I just got this one to replace a POS cheapo cable. The StarTech is rock solid and, for my $$$, worth the price. I'm pretty sure most FiiOs work with the N7, but you can always google to be sure.
If you any high resolution FLACs (24-bit, 96 or 192 kHz), I'm pretty sure this is the only player that will play them at their native bit depth and samplerate. I'm just getting into USB audio on my Nexus 7 2012, but I tested the trial version of USB Audio Recorder Pro (UARP) with my HiFimeDIY Sabre U2 Asynchronous DAC, and it played a 24/96 FLAC perfectly. I haven't had a chance to test USB audio with any other players, but UARP is unique in that it has its own USB audio driver that bypasses (or attempts to; no problem w/the N7) the Android audio chain.
There's this USB-centric ROM available, if you're inclined to explore. Seems quite popular and has some nice features.
If you have a lot of apps installed, Titanium Backup Pro might be worth buying. It can be handy for restoring apps if you decide to try other ROMs. There's a free version, too.
Lastly, as a noob, you might appreciate WugFresh's Nexus Root Toolkit (NRT). Handy if you don't want to use the commandline and Android SDK. I started with it, learned the principles behind what it does, and now use the SDK for most things, but sometimes his NRT comes in handy.
Hope that helps! Good luck

ThurstonX, I'm actually thinking about buying the Hifimediy Sabre U2 but had a question. Say if I was playing 16bit mp3 songs or using Google Navigation...would you actually hear sound through the Sabre or does audio only work through UARP?

Wish I could answer your question. I never got the DAC to work with any other player. I use the stock 4.3 ROM and vorcers' V7 kernel. I have Timur's USB ROM (which uses his kernel) downloaded, but haven't had any time to test it. Hopefully tomorrow, but whenever, I'll post another reply to let you know.
My understanding is that if you get the DAC working, it handles all audio out, if you have a player that will do it. Maybe that's why people love USB ROM. I mean if guys are using it for their Nexus 7 car installs, with Bluetooth and other audio apps, and are using USB DACs, I would assume all audio will go that route.
Sorry for being so vague.

So, i have been reading thread after thread...AFTER thread on here and tabletroms.. and a few other choice places.. I just got my Streak 7. I have learned to root it, CMW, NVFLASH, etc.. i'm good on all these accounts.
i updated my streak (t-mobile 4g) to newest dell rom and liked it.. it fixed the dock speaker issue (no sound out of speakers when docked.) i rooted it but realized the kernel wouldn't allow overclocking (which i want to do for my tablet purpose)
So i switched over to Honeystreak r8 which is working perfect.. EXCEPT the dock issue is back.. docking the tablet (official v.2 dock) regardless of what you choose, shuts off internal speakers. So.. what am asking here is..Is there a rom that allows OCing.. and sound out of speakers while docked? Where can i find just a kernel i can flash with CWM on stock rom that allows overclocking (honeycomb)
second question, build.prop. i have looked EVERYWHERE and no one has mentioned this.. The marketplace (play) is not complete. Many apps are "not allowed" on this tablet. I know the "fix" of editing your build.prop with a proper/different product and fingerprint but whats a good one? I would like to install Hulu and a few other things WITHOUT sideloading. I can;t be the first person to ask this.. but i have searched all forms of combo words to get an answer and have not found one.
Last question. I read that the offical dock supports USB Host, i guess through the USB plug on the back... yet official rom does not support this.. (right?) So.. How do i plug a hub into it (it's a female Mini-USB NOT Micro) and also WHAT rom/kernel/whatever supports it..
Thank you..
The dock issue was fixed with stock rom 514, and HS R8 is based off of 507.
You would need to use 514 to get the fix, it might be possible to hack those two together and get both, but it hasnt been done yet. Also DJ_steve has no plans on HS as he's been working on ICS.
If you're unsure about rom versions, see Dell Streak 7 Official roms - xda wiki and
Dell Update process for an explaniation on the version strings.
Depends on the app, best thing to do is find out why it's not compatable in the first place. Some apps (like hulu i think?, or was it netflix?) use whitelists, which means only those devices can use it.
You could use a popular device like the transformer or xoom, or a similar device like the Gtab 7 which has similar specs (sorta).
The stock kernel doesnt support much in the way of usb-hosting. The HS kernel might, but also I believe you must provide power yourself, the port doesnt offer much power at all or so I hear. I'll have to get back to you on that in a few weeks.
How bout a kernel.. is there a place or is there a download of just an OCed/ OC capable kernel for the stock-rooted rom? That would solve one of my major dock issues. But i bought this device to make it a nice little portable arcade/emulator box and everything is great but i need to OC the thing to make some emulators really run nice. and i use the dock to.. well.. hold it up and charge it.
Also, do you know where i can find galaxy tab 7 build.prop examples?
There's no other kernels besides the HS one, (if you dont count the ICS one).
You cant just install it over 514, HS is partitioned differently.
I recently got a carrying case for about $8 for my kfhd. It also comes with a built in keyboard, which is very cool. To see if I could use it, I also purchased a micro USB to USB in order to connect, but it doesn't work at all.
I'm assuming this is because of the closed os. Once a bypass or stable ROM gets released, will using an external keyboard ever be a possibility?
I've seen the nexus 7 connected to a micro keyboard via usb so its a possibility if you went with a straight android ROM, but the bootloader still needs to be cracked first. I can't remember if the KFHD has bluetooth, otherwise you can try bluetooth keyboard.
Edit: appears that KFHD only has bluetooth for headphones and speakers according to their site. I just returned my KFHD and got a Nexus 7 and typing with my HP touchpad bluetooth keyboard on my Nexus 7 Small things like this, not even being able to use an external keyboard right off the bat adds to the list of returning the KFHD making me go with another device.
Yes, I suppose it's only a matter of time before someone gets the bootloader to work.
I'm hoping my time invested in waiting will pay off with better hardware capabilities
I didn't want to play that wild card so I returned my KFHD and picked up the N7. There were devs exchanging comments on a thread in the general section but any talk on there seems to have ceased, so that is not a good sign in my opinion. I'm sure they are working on it and I'll kick myself when the bootloader unlocks but its not a chance I can take right now.
If you have a BT keyboard in hand, doesn't hurt to try. Someone said they got a BT game controller to work.
Know I know this seems far fetched and has nothing to do with android, but could I download a firmware update for my TV (which is installed via a USB flash drive) and extract it and replace the image files.
Most TVs seem to run on the same software so if they get it working for one, it should work for all.
I just think the ui is really ugly so I was just curious if anyone has ever tried such a thing.

Well, the reason you can mess around with Android is cause its open source. This TV software is very likely closed source. Not impossible, but much more difficult to modify. Ive never heard of it personally
You could buy something like an Odroid or those Chinese flash drives which have android pre-installed with them. Also you could try a raspberry pie with Android.
First off your TV's insides are almost certainly not standardized enough for such a thing. Second there just isn't really a demand for such a thing in the first place. Smart TVs already exist, as do USB smart TV dongles.
Wish we could flash a new TV into our watching room...
Frigging Samsung plasmas suck! fixed once under warranty same problem almost exactly a year later.
Bizz! You could just connect your android phone through HDMI too! Becomes a poor man's smart tv

Does someone tried an external dac on the G2? Does it work? Every DAC is compatible? I ask this because I have to buy an USB DAC for other purposes and, before buying, I want to choose one (if exist) that can be compatible with g2
You'll need to provide more details. Are you trying to OTG connect a DAC? If so, it probably won't work. Those not intended for Android use will not contain drivers for Android phones.
If you're looking to buy a NuForce Icon or FiiO E18, those will work because the G2 supports OTG, and the majority of custom ROMs retain that functionality as well.
So just post what DAC you're looking to buy. You're got every reason to be forthcoming. There's no way to tell without knowing the specific model DAC. If it's intended for Android use (i.e. the manufacturer advertised it as compatible) then it should work.
There quite a few that work with both nexus 7 ...so i wouldnt thinkg it being g2 would matter as long as its comptatible with other android over otg should work for g2 ..... Im getting a fiio e17 or e18 soon.

I don't have a dac but I need to buy one to be used with my hifi. I don't have choose a specific one and I ask here if there is someone that tried and get a dac working on g2.
Edit:
I have a usb headset, the corsair vengeance. That is not a dac but act like an external sound card. I connected it with usb otg cable and get the sound, but only the music played throught 'usb audio player pro' trial version. Is possible to get all the system soud directed to the external sound card/dac?
Edit2:
Found this thread
http://forum.xda-developers.com/showthread.php?t=867274
That means that we need modified kernel?
I have an fiio E17. It works with the G2 but i have clicks sometimes. For more than 16/48 I need USB Audio Player.
Hifimediy Sabre Asynchronous here, on CloudyG3 with the included kernel. Works fine, clicks sometimes when I start playback.
Got rid of clicks with the following additions to build.prop, normally used for Viper4Audio:
lpa.decode=false
lpa.releaselock=false
lpa.use-stagefright=false
tunnel.decode=false
Edit: False alarm unfortunately. But I have much less of them.
although this is a G2 FOrum I have a G3...
was looking for some answer to find out how to get rid of all the clicking or pops with an Asynchronous DAC/AMP. I have a HRT Microstreamer.
Anyway to fix or we all waiting for L?
Here dorimanx dev made a kernel that supports audio out to every usb device, so now every dac or usb soundcard are supported.

I can confirm the newest dorimanx kernels support precise streaming, limited to 16/48 by Android of course.
I would like to connect the HTC One to a LAN port via a usb-ethernet adapter, for wired internet access.
I know some phones such as Nexus 5, and tablets like nexus 7, 9, 10 have the functionality.
Does the CM on HTC One have this functionality? Can it be loaded?
Thank you.

Very much so.. I've done it myself using a USB otg to ether adapter.
With a off and root with the rom of your choice (revolution, coin etc) - install the kernel from flar.
Elemental × version 14/20 depending on whether you're phone is Google edition, sense 6 or 7.
The kernel allows all sorts of capabilities. I have even played games using xbox gamepad. This kennel recognises way too many things to list.
Long as your ether adapter is compatible with an average win 7 or Ubuntu then it should auto install drivers on phone. Certain Chinese cheaper accessories aren't recognised as their chips are probably incompatible.
Any search should get you to the download link. Read it, understand it thoroughly before flashing kernel. Nothing should happen if common sense is used. I'm not aware of your experience in this so just letting you know not to yell at me if something is installed incorrectly. ?

Thank you for the reply and information. It is great to know such a possibility exists.
Unfortunately I am totally new to this, and have no clue how to install kernels or change settings at that level!
If you would know of a tutorial on the web that is geared for novices like me do let me know.
Also, are there kernels to enable using the ppp2 widget with a usb modem for phones?
Thanks again,
