tanx but the kernel not ziped file !! how to flash img file in TWRP recovery?
[Nexus 7 Android Development] Zeljko1234:
I explained few pages back. One way is to replace boot.img in flashable rom zip and flash rom.

Another is to boot into fasboot and then:

Fastboot erase cache*

Fastboot flash boot boot.img*

Fastboot erase cache*

[Nexus 7 Android Development] ecossais:
This ROM is for the 2012 Nexus 7 wifi (grouper) and you have the 2013 Nexus 7 lte (deb). Do a search for roms for 2013 Nexus & lte and I am sure you will have success.

Volume, sleep

So, I have my 2012 N7 setup for fixed installation in my car, and until today was using Timur's USB rom, but I needed a change... So are there any good software solutions for volume control on screen? Also, I understand how I can keep my screen on using Tasker, how do I enable deep sleep? Obviously USB-Rom automatically does that when FI mode is enabled, and it stops music/etc... Sorry if this has already been asked.

*edit*: I read the past 25 pages or so, I think I might just make tasker profiles to turn airplane mode on when the screen goes off, and hope that stuff doesn't cause too many wakelock issues, we'll see... and it seems like when the DAC is disconnected, it automatically will stop audio... I'll give it a go. As far as volume control goes, the TabletUI mod I know is gone and not possible, I wonder if there's a reason volume keys couldn't be added to the "Buttons and layout" under the "interface" settings, it would be ideal for my setup. I'm trying to figure out a better way to just be able to tap in a single spot to raise/lower volume.

Other than that, it seems speedy, I'm on most current build with NetFluke's v5 kernel, my DAC is working swimmingly, and can be hotplugged.

Beware - CM11 has a nasty Bluetooth bug

Details are in my message in CM11 thread http://xdaforums.com/showpost.php?p=50501277&postcount=3048

Do not use Bluetooth mice if you do not want unexpected reboots.

So far reproduced on CM11 official 02/20, this ROM and Carbon ROM. Testing SlimROM now, but expect the same issue.

Whatever Cyanogen guys changed in their BT after 01/20 was not good.

Sorry, but this is above my pay grade to fix. Logs are in my CM11 thread message.

Update: submitted bug report to CM. Let's wait.
[Nexus 7 Android Development] jmhalder:
It's a solution, but far from elegant, since it will either get in way, or be hard to see if it's too translucent... it works, and it's what I'm going to use for now and I appreciate the suggestion. But I'm thinking of drilling a hole, using something like this: http://www.amazon.com/Fusion-Control-Powered-Controlled-Rotary/dp/B00ANRRZCG/

hardly a cheap solution, but also probably the nicest, even though it doesn't look like it comes with a knob, and I'll probably end up hot glueing it in there.

Both are great roms I just have minor random things that happen with both and I would like to try this route. I have tried putting in your script and placing all of the files in \system\lib\modules but apparently there's more to it than that. I would be using his latest usb dac rom, netfluke v5 otg kernel, and hopefully your ezcap drivers. Any help would be greatly appreciated.

This is not that simple. The modules are built with kernel source, and will only work for that kernel.*

But.......

The GPL is your friend and Im its biggest fan. Just tell zeljko or netfluke to look in my github and kang the source for the drivers. Then, they can build them against "their" source and the drivers will work. I do believe that netfluke's kernel would be better with a cm11 rom, because it is a pure cm11 kernel, with the dac otg stuff added. Of course if he needs any assistance ill be glad to help.
[Nexus 7 Android Development] la.ouiche:
Hi everyone here,

I'm new to this thread, tried to read a maximum to sort out my issues, but I may need some help...

Let me explain: I wanted to install on my N7 (and yeah it's a 2012 wifi 32GB) the CM11 ROM from Zeljko1234, with the Netfluke kernel to add FI-Mode (I plan to put the N7 in my car, obviously ^^).

To do so I've downloaded this ROM version:

cm-11-20140217-zeljko-UNOFFICIAL-grouper (I didn't take the latest cm-11-20140220 because of the bluetooth issue reported).

And the kernel (from this post http://xdaforums.com/showpost.php?p=50417390&postcount=499):

CM11-OTG-v5.img

Not sure if I did it right but from there I've renamed CM11-OTG-v5.img to boot.img and replaced the file into the cm-11-xxx.zip

After that I installed the ROM, no problem at all. Now I'm running this ROM, all seems to be running well (it claims it runs kernel 3.1.10-g90cc2c9b1-dirty). I'm letting dalvik do the runtime (art seems to be more ram consuming and so with heavy multitasking it leads to some hangs-up, IMO).

It's great but I don't know how to access options for the FI-mode. I've connected a simple OTG cable, and I've been able by plugin a USB cable (mini usb with one additional usb A for power) to make my auto-alim HDD work (if I don't plug another power source nothing happens). It's working great, reading the NTFS content works like a charm. I can see it in the storage section of the parameters, but no new section under 'System' parameters.

I thought that with the OTG cable plugged in I would have acces to FI-mode and its parameters.

Did I made something wrong? Or missed something? Where I can setup fast charge?

Sorry for the verbose post that do not help anyone at all... But if one comes with some help it would be nice :D

Edit: Not ROM related, but I would like some advices on the car installation I'm planning to do (ideally I'll try to include the tablet in the dashboard). At the moment I don't know which direction to take. I will keep my actual built-in stereo car, and use the analog headphone from the N7 to output all sounds (so not interested in usb dac). I have a analog remote control on my steering, and would like to take the cables and be able to control the multimedia functions on the tablet. To do so what can you advice me to interface with the usb?

I've seen the Arduino module, and wonder if I could do something with it, and drive medias on the N7 through usb commands. Using the Arduino would virtually allow me to add any buttons to do whatever I want where I want on the dashboard. I even imagine to interact with some LCD display of the car, kind of setting up a second multiplex in the car, that could retrieve values from the elm327... and may be other things with servo, sensors... I'm a dreamer. But it looks so flexible.

Can be pretty cool, but my knowledge on this is null. I guess it will be necessary to write an app to communicate properly or standard android integration can be enough? Any ideas?
[Nexus 7 Android Development] NetFluke:
FI/OTG charging controls

Here's how to enable FI mode and OTG fast charging:

create a text file named 55userinit in /etc/init.d folder and add following lines to it:

#!/system/bin/sh

#This line enables FI mode

echo "1" > /sys/kernel/usbhost/usbhost_fixed_install_mode

#This line enables OTG fast charging

echo "1" > /sys/kernel/usbhost/usbhost_fastcharge_in_host_mode

#End of file

Save, change file ownership to root:root, permissions to 755 (rwxr-xr-x) and reboot.

Please do not enable OTG fast charging if you plan plug your device into computer's USB port - excessive current draw from Nexus can damage your motherboard.

This ROM does not have separate entry in Settings to control OTG parameters, sorry.

To NetFluke

any chance of an updated cm kernel? I have tried every kernel and so far everything is a failure at detecting my external HDD.
[Nexus 7 Android Development] acidspider:
Will this rom Support all f2fs partions soon?
[Nexus 7 Android Development] dvdivx:
It would need a new kernel and a new rom and f2fs would break the OTG features thanks to SELinux. Never saw the point to f2fs since it breaks so much stuff to make it work. I'm just hoping for an update but CM11 broke external HDD support sometime around March 1. Other ROMs don't even work.
[Nexus 7 Android Development] la.ouiche:
Thanks. Is the app PowerEventManager working as expected?

EDIT: I answer to myself. In addition to the command lines given, the app works to go in FI mode and fastcharge.

[Nexus 7 Android Development] Zeljko1234:
I completely agree with you. Couple of builds had problems because CM team changed something. Last week I made build without NetFluke modification and didn't notice any improvement.
[Nexus 7 Android Development] dvdivx:
I think he just meant an update to current CM11
[Nexus 7 Android Development] Zeljko1234:
Thanks to NetFluke somewhere in this post you may find Easter egg :D Also, for users who wish to have OTG kernel with charging, there's one more and even another one :P

I'll let you to "find" Easter eggs by yourself and enjoy in build synced with latest CM11 repo :)

Hi Zeljko1234,

Any chance to get the features of the 'USB ROM' in your CM11 rom?

[Nexus 7 Android Development] Rage2:
Zeljko1234, If connected with a usb sound card, then not working microphone....((( pls fix it
[Nexus 7 Android Development] Zeljko1234:
"USB ROM" is actually original idea from where NetFluke made modification for this rom. Not all features, of course. But DAC should work and with additional kernel (check my previous post) OTG charging also works.

Unfortunately no, because of several reasons, lack of time, I don't have USB sound card and the most important of all, NetFluke has done all this DAC/OTG modifications.

Any special install instructions or just boot to recovery and flash?

[Nexus 7 Android Development] Zeljko1234:
Nothing special, as explained in the first post or flashing any other rom. If you wish to use OTG kernel with charging replace those two files in zip (rename boot-otg-img to boot.img) or flash kernel manually later.

I must be doing something wrong...

I installed the most recent ROM, 20140419 and my DAC (UCA202) worked fine after boot. It did not seem to be hot-swappable though.

Then I did a fastboot flash of the boot-otg.img so I can charge while on OTG. Charging with OTG was successful, but now I get nothing from the DAC, even with it all connected at boot. The DAC light does come on though, so the tablet does see the DAC.

Am I missing something here, or doing something wrong?

The only other thing I did was add the PowerEventManager.apk

I would love to get KK in my car instead of JB (USBROM).

Thanks for your work and any suggestions!
[Nexus 7 Android Development] Aaron061992:
very good but some weird bugs

Thanx,

This is wonderful... my usb otg was broken for months, counldnt find a fix... this rom did a great job.

however, there's a weird problem. i cant seem to scan media! so mx player and apollo/ google music libraries are staying blank... i have tried media scan apps in the market, they all force closes. any tips? i had this problem in cm 11 m5 but only with mx player.

also my battery drains a lot (for weeks, before flashing. tried stock, cm 11 m5 but same results), when screen is on, it discharges even while charging. however charging is way faster with this rom, but that discharging is just not gone...

i had some high hopes about art, but change is almost unnoticeable in my case till now...

using 20140106 build with inbuilt kernel and art (gapps-proper-art)

thank you again
[Nexus 7 Android Development] dvdivx:
don't use art and it should work.
[Nexus 7 Android Development] Aaron061992:
I just tried using dalvic and re adding the music files. still doesn't work. however, n7 player can detect the music files (apollo or any other music app depending upon system media storage scan doesn't work) and quickpic can detect images. found no solution for video files. however i dont like n7. is there any other music player having the manual storage scan option? ttpod was my earlier favourite but it has gone chinese :(

btw, a solution that will make the inbuilt media storage scan work properly will be much more appreciated...
[Nexus 7 Android Development] Aaron061992:
Sorry, it was all my silliness... I just found some rouge .nomedia files lurking all over my internal... no idea from where! weird...

P.S.: Everything is fine again... Battery began to charge after a day, now it's like new!!! USB MTP was not working before (stock 4.4.2 was at first very buggy, then just simply stopped working telling me some **** about broken hardware error) i came to this rom!!! USB OTG is great, almost like plugging into a laptop... however, my external hdd still doesnt work :( (was never working, but i was hoping this wonderful rom has more miracles under its sleeve :) :) )

Only minor inconvenience is gt racing 2 crashing once a while (never during races).

Overall this is EPIC. thank u a lot.
[Nexus 7 Android Development] dvdivx:
I just use this rom: http://temasek.hopto.org/?dir=Nexus%207%20-%20Grouper/CM-11.0 and the kernel and cifs.ko from this thread and have never had a problem with MX player either finding local files or files on a network drive.

Hi,

I've been trying to find a way to charge my Nexus 7 2012 3G (Tilapia) from a Y OTG cable, while using it with a USB MIDI interface, and I came across this post.

Does this only work with CM11? I have the stock KitKat, with the mod to re-enable SMS support. Ideally, I'd like to stick with that but fix it so it will charge while using OTG. Is that possible?

Can it only be set to fast charge, by this sort of method? I might want to connect it to my PC, or use it with a USB MIDI keyboard, without the Y cable and power supply, some times. Isn't there a way to just make it draw the more or less standard 0.5A?

[Nexus 7 Android Development] Zeljko1234:
Just use gapps listed in the first post. I use this rom since is built (30. of December) without issues.

No recent updates in CM repository, so no need to build new rom.

About add-ons, when CM starts with nightly builds I'll start with cherry-pick. Maybe even earlier but will keep pure CM also.

Hi, now i'm on koko98's release, but i will flash yours, because is newer :)

I have one question, can you add THIS, or make it as Add-on? :)

Thank you

To all with ART

what do you say about it? Is better than Dalvik? Should i enable it?
[Nexus 7 Android Development] abuttino:
I am not sure why people are discounting ART, I have it on my Razr HD and it's phenomenal.

The first thing I've heard here is that the Flash memory chip may be weak. If this is true and what I know about ART, it would seem that you'd want ART. If you use Dalvik, it has to compile all your apps every time you run them, When using ART, it compiles the first time you power up in ART mode, and that's it.

The second thing, ART is noticeably faster. It's proven. Look at benchmarks with ART, the only thing it didn't seem to do well with is gaming. I'm not a gamer and disable anything like it, so that didn't matter to me.

ART is experimental but will be on EVERY device by the time the we are eating the next desert :) (Enjoying the next Android ver)

My suggestion is "Try it for yourself". For at least 1-2 days and notice the smoothness that it has. I am moving to this or koko's build (whichever is newest each day) because I am sick of Tasker running out of memory, ART will solve that too.
[Nexus 7 Android Development] Zeljko1234:
abuttino, good thoughts about ART. For me also works fine, including one game I have installed.

Just making new build... ;)
[Nexus 7 Android Development] abuttino:
I was just about to flash the one in the OP.. I hate asking this question but when do you think it'll be done?
[Nexus 7 Android Development] Zeljko1234:

[Nexus 7 Android Development] n0M3n:
I'm using ART, but when I open Maps or just reboot the device fc of text-to-speech engine happens. WTF?
[Nexus 7 Android Development] abuttino:
Go into any root explorer, then find the system/priv-app directory/folder, mount as rw, delete googletts and googleears apks, restart and download the Google text to speech engine on the play store, as well as sound search for play. These gapps on the first page are definitely not suited for art, if you want, try the gapps in my signature on my last post. I am pretty sure they'd work
