This ROM supports USB audio (the only one I could find to work after a day searching on XDA). But the Surround Sound option in AudioFX seems to do nothing when a USB audio device is connected. However the worst thing is that DSP Manager is now missing in favour of this slick-looking but ultimately nowhere-near-as-good as DSP Manager and its the Virtual Room Effect. The libraries needed by DSP Manager are libcyanogen-dsp.so/libreverbwrapper.so/libvisualizer.so etc. but the first isn't on this ROM. Tried installing DSP Manaager from CM11 but get this error:

E/AndroidRuntime( 3395): java.lang.IncompatibleClassChangeError: The method 'byte[] android.media.audiofx.AudioEffect.intToByteArray(int)' was expected to be of type virtual but instead was found to be of type direct (declaration of 'java.lang.reflect.ArtMethod' appears in /system/framework/core-libart.jar)

Overall, it's working very nicely after a week, with F2FS and Gapps-free, even though I neglected to follow the instructions and converted to F2FS with TWRP 2.8.6.0.

Looking forward to the exciting future integration with Microsoft services ;)
[Nexus 7 Original Development] fireforhire:
Are there any kernels that work with the nightlies and f2fs data/cache? I tried metalice alpha 74 for 5.0, and it doesn't boot.
[Nexus 7 Original Development] agentfazexx:
12.1 is official: http://download.cyanogenmod.org/?device=grouper

Will not boot over CM12. Have to do a clean wipe.

Edit: CM12.1 won't boot after a factory reset. Just spins. Nice first release! Don't flash it guys.
[Nexus 7 Original Development] phatpaw:
I downloaded and flashed after a wipe. Working fine.

I'm disappointed that I still cannot play back on Google Play Movies in 12.1. Couldn't in 12.0 either.

I cannot seem to figure out what the root cause is.
[Nexus 7 Original Development] peti0118:
Flashing soon and testing.

UPDATE: Working flawlessly.
[Nexus 7 Original Development] Caleb_cz:
Works fine here. I did dirty flash + minimal gapps 5.1
[Nexus 7 Original Development] fran_xda:
Cm12.1 working OK but I have these issues, after wipe and flash, minimal gapps:

- Google maps not showing my position in saving baterry mode. Other apps do.

- Cannot sync calendar

- some list are slow, like not hardware accelerated, for example the notification sound list for gmail
[Nexus 7 Original Development] agentfazexx:
So how do I get it to boot? Maybe it doesn't like the a75 kernel?
[Nexus 7 Original Development] Vnvjeep:
I just dirtyflashed it on top of stock 12.0 4/15 nightly with no prob. Also, my data and cache are formatted f2fs and its flying!
[Nexus 7 Original Development] agentfazexx:
I did a factory wipe, wiped system, installed ROM/gapps/SuperSU and rebooted. Just spins at the boot animation. Am I bricked or something?
[Nexus 7 Original Development] Vnvjeep:
Can you try loading a CM12.0 latest nightly again, and then flash 12.1 ontop of it?
[Nexus 7 Original Development] agentfazexx:
Flashed CM12/GApps...then 12.1/GApps after clearing cache/system/dalvik...rebooted. Still does not boot. Stuck at the animation. How long does the first boot of CM12.1 take?
[Nexus 7 Original Development] Vnvjeep:
It went relatively quickly... perhaps a minute or 2? Which Gapps are you using? Can you try flashing just 12.1 and not Gapps?
[Nexus 7 Original Development] agentfazexx:
Using gapps-lpmr1-20150324-signed.zip

---------- Post added at 12:40 PM ---------- Previous post was at 12:35 PM ----------

Tried flashing JUST the ROM, kernel and supersu zip...still doesn't boot.
[Nexus 7 Original Development] Reptilez_DK:
Am I missing something, or did you not try without flashing a 3rd party kernel ? :)
[Nexus 7 Original Development] agentfazexx:
Tried that too.
[Nexus 7 Original Development] JuggaloDroid:
Is anyone else having issues downloading today's build from the cm updater? I also tried going to the website, but got a gateway error on that front. Thanks in advance :good:
[Nexus 7 Original Development] agentfazexx:
Site's been down all day.
[Nexus 7 Original Development] JuggaloDroid:
Thank you for the quick response :good:
[Nexus 7 Original Development] agentfazexx:
CM download site is back up.

---------- Post added at 02:48 PM ---------- Previous post was at 02:27 PM ----------

4/18 doesn't boot either... How do I get this to work?
[Nexus 7 Original Development] GtrCraft:
another twrp and wipe everything except storage, if that's not working factory image
[Nexus 7 Original Development] agentfazexx:
CM12 works. I did a full wipe, installed that, flashed 12.1 and same result. I already did wipe everything except storage and I'm on the latest TWRP. So now what?
[Nexus 7 Original Development] GtrCraft:
Flash the factory image, after backing up your files. Can't think of something else
[Nexus 7 Original Development] agentfazexx:
Why factory? CM12 works. 12.1 does not.
[Nexus 7 Original Development] GtrCraft:
Because nothing else works, and 12.1 works for me and other people

And don't use M-Kernel, it doesn't work on 5.1
[Nexus 7 Original Development] agentfazexx:
I tried JUST flashing the ROM, nothing else, and it doesn't boot.
[Nexus 7 Original Development] Reptilez_DK:
Last time I had problems with my N7, I flashed the oldest factory image available, and let it update itself, to the newest version. Then started all over, flashing recovery, ROM and gapps. Other than that, I have no more ideas. :confused:
[Nexus 7 Original Development] rfrenz:
This may sound ridiculous but someone in XDA suggested reverting to CM 10.2.1. I did. I now have TWRP 2.8.6.0 and the old CM 10.2.1 ROM installed and my ancient Nexus 7 is a lot happier than it has been with the newer ROMs. However, the only things I use it for is Kindle, weather and gmail/calendar. I'm seriously considering trying Ktoonsez's f2fs converter just to see what happens. The converter works well on my S5 but it may require Ktoonsez's adaptation of TWRP recovery to install properly. I haven't quite figured that out yet.
[Nexus 7 Original Development] sroma1980:
12.1 is awesome!

Just installed latest 12.1 version (18/04). Had a problem with google apps in the beggining! Some fc's but entered in recovery flashed gapps-lp-20150222-signed.zip and everything is working fine. No more fc's! I gotta say thys is by far the fastest rom i have ever had on my nexus 7. The difference in performance for the 5.02 versions is just mindblowing!

Excelent work!
[Nexus 7 Original Development] agentfazexx:
How did you get this to boot? I can't with a full factory wipe.
[Nexus 7 Original Development] sroma1980:
I think the problem is in the recovery. I have multirom installed through playstore and then installed their recovery , not the kernel!

Always have used theirs. Then just downloaded 5.1 18/04 and isntalled it from recovery. That was it!

Problem with google gapps in the beggining, but then instaled gapps mentioned above(gapps-lp-20150222-signed.zip) and wiped cache/dalvik cache.
[Nexus 7 Original Development] agentfazexx:
I'm using the latest TWRP.... Are we using CWM again or something?
[Nexus 7 Original Development] sroma1980:
Nope. Multirom uses TWRP. A version of theirs
[Nexus 7 Original Development] agentfazexx:
Not using Multirom. Just trying to get 12.1 to actually boot.
[Nexus 7 Original Development] dabl8:
I tried dirty flashing the last two nightlies but there's a memory leak and the system memory as shown in Settings grows and grows until it maxes out after 15mins. It's OK with a clean flash; however the system uses about 400MB whereas 5.0.1 used about 300MB IIRC.
[Nexus 7 Original Development] claudio8:
hello guys,

I would like flash latest cm 12.1 but on my N7 I'm using the F2FS system with 4.4.4. I'm wondering if is possible convert the cyano by convert f2fs app.

Anyone had a problem to do that?

thanks in advance
[Nexus 7 Original Development] agentfazexx:
Still unable to get CM12.1 to boot...
[Nexus 7 Original Development] GtrCraft:
Better use system with ext4, f2fs is only better in data and cache. Which cm12.1 support by default
[Nexus 7 Original Development] agentfazexx:
Flashing back to stock 5.1. I'll try CM12.1 later on once that's all done. Maybe that'll fix it? I don't think I have the 5.1 bootloader so I wonder if that's part of it? Also... I don't HAVE to be formatted as f2fs for CM12.1 to work right? My Nexus 6 is fine without it.
[Nexus 7 Original Development] Vnvjeep:
I didn't have to go through all that... Went from cm12 to 12.1 with a dirty flash. I did format my cache/data to f2fs... And this is the gapps I'm using. http://xdaforums.com/android/software/gapps-google-apps-minimal-edition-t2943330

Good luck!!
[Nexus 7 Original Development] agentfazexx:
CM12 boots fine. Stock 5.1 is having trouble too. Might just be taking long though.
[Nexus 7 Original Development] bangsergio:
CM12.1 clean install experiecing auto rotate issues any fix already?
[Nexus 7 Original Development] agentfazexx:
Formatted data/cache with f2fs... I can't get to it via Windows Explorer anymore.

---------- Post added at 04:11 PM ---------- Previous post was at 03:47 PM ----------

Fixed the above.. So I literally started from scratch, went back to stock, locked the BL, unlocked, rooted, flashed TWRP (all from the nexus root toolkit) then flashed CM12.1, franco kernel (for 5.1), GApps and supersu... Still spinning at the animation. Guess my tab just won't take CM12.1 for whatever reason.

Oh well, time to eBay it.
[Nexus 7 Original Development] sroma1980:
I think your problemas is franco kernel. If im not wrong it does not support cm12 or hás some issues with it. Try cm12.1 stock kernel
[Nexus 7 Original Development] agentfazexx:
I flashed this with JUST the ROM and nothing else. It does not work with my tablet. Flashing ROMs is obviously simple, and it doesn't boot.
[Nexus 7 Original Development] fran_xda:
I once had lots of issues because I forgot to check md5 and download was corrupted.
[Nexus 7 Original Development] raptir:
So I put CM 12.1 on my Nexus 7 to try to breathe some new life into it. I'm running into an error with any Google apps. For example, when I open Gmail I get the message:

"Unknown issue with Google Play Services."

I've checked my MD5s and I tried reinstalling fresh again but it's occurring each time. This is with the 4/19 build and the GApps that are linked here. Any suggestions?
[Nexus 7 Original Development] joaopaulo_:
the link in the first post are 5.0.x gapps. Look for the 5.1.x gapps and install it. The problems with google apps go desapear.
[Nexus 7 Original Development] agentfazexx:
Tried several downloads. Isn't that
[Nexus 7 Original Development] raptir:
Thanks, I just tried it using the 5.1 Gapps on the CM wiki and I'm still seeing the same issue.
[Nexus 7 Original Development] dandemonic:
I clean flashed with the 5.1 base package delta gapps from the OP of this thread http://xdaforums.com/showthread.php?t=2997368 and have had no issues at all so may be worth giving a try.

If you're having issues with Gmail, in the delta gapps OP are also addons for the gmail exchange service and gmail app, which are 5.1 compatible.
[Nexus 7 Original Development] anoob4eva:
I am having this same problem on my Samsung Note 3... let me know please if you find a solution.
[Nexus 7 Original Development] DarCas:
After I upgrade to 12.1, I can't find OTA nightly update. What can I do?

Has anyone gotten any kernels to boot on 12.1?
[Nexus 7 Original Development] mattbirks:
Has anyone logged it as a regression defect from 12.0?
[Nexus 7 Original Development] ZeroDs111:
Any news about 12.1.1?
[Nexus 7 Original Development] peti0118:
They already merged 5.1.1.
[Nexus 7 Original Development] :
... for ages [emoji2]

So SOrry, how i see 12.1 i thought the 12.1.1 wasnt released

Thanks :D
[Nexus 7 Original Development] fireforhire:
So no kernels work with nightlies other than stock?
[Nexus 7 Original Development] tronmech:
Moved to cm 12.1 May Day build. If I su from the Terminal emulator, it reboots. Also, I get install failures for Bloons td5 when Installing from the Amazon appstore. I'll try to get a logcat for the second. Would a last kmsg be useful for the first?

Logcat for install failures:

[Nexus 7 Original Development] mattbirks:
So, cmupdater works great for me since 4th May nightly.

Now getting "unfortunately, Gmail had stopped" pop-up every few seconds now. This is the same with 4th, 5th and 6th nightlies. Tried reinstalling pa-gapps with the nightly, but still there.

Pretty much unusable at the moment, which is a shame because performance was getting pretty good.

Anyone else getting this?

Matt.
[Nexus 7 Original Development] aoh1996:
Got this too. I refleshed the rom wiping data and system, booted up, then again reboot in recovery and installed gapps. Now seems to be OK. The only problem that i have no sound when change volume level.
[Nexus 7 Original Development] mattbirks:
Don't think I've had sounds when changing volume with any of the cm12 nightlies.
[Nexus 7 Original Development] aoh1996:
It's my first installation of cm12, so i don't know how it was before [emoji4]
[Nexus 7 Original Development] Reiven89:
Just wanted to report my experience with Cyanogenmod.....first flashed with data and cache on f2fs and i experienced lag sometimes. Then i wiped , formatted and flashed the Rom in full f2fs i notice a great difference in performance and i have 0 lag......imho full f2fs is the only way to go for our Nexus 7 2012
[Nexus 7 Original Development] Vladimir2k9:
What kernel do you use? How to move to full f2fs?
[Nexus 7 Original Development] Reiven89:
I just format in full f2fs, and then flashed latest nightly....the installation will detect the used partitions. No need to change kernel.
[Nexus 7 Original Development] Vladimir2k9:
/system also f2fs?

Does it now supported?

I think our rom need more optimizations. If I changed I/O sheduller to BFQ, device work faster, but not so fast then AOSP.
[Nexus 7 Original Development] Reiven89:
Yes system also on f2fs.....as i said before, i noticed an huge improvement of the performance with all partitions formatted to f2fs

As far i can see, it is supported.....the rom automatically detect the partitions when flashing

I do not have any lag or slowdowns now
[Nexus 7 Original Development] :
Are you sure you're on f2fs with your system? The reason I'm asking is, even when I'm changing system to f2fs (with twrp 2.8.6.0) flashing cm12.1 (today's nightly) changes the system format always back to ext4 ... funny.

Cache and data are sticking.

Any idea?
[Nexus 7 Original Development] Reiven89:
My bad, you are right, system after flashing goes back to ext but still there is a great improvement over all ext .... sorry about the mistake....
[Nexus 7 Original Development] :
No problem at all.
[Nexus 7 Original Development] dandemonic:
Is anyone else getting system UI fc on 13/05 nightly?

Had to restore my backup. Bug report didn't work with UI crash.
[Nexus 7 Original Development] linuxxxx:
Please, skip today nightlies
[Nexus 7 Original Development] mattbirks:
Yeah 13/5 was broken, but I'm loving 14/5. Most responsive of the 12.1s so far for me. Don't know what was done, but it's good.
[Nexus 7 Original Development] linuxxxx:
Today builds have some new features for your grouper and tilapia:

- cpu_input_boost: will improve your performances without affecting battery (it's off ATM, but you can toggle it manually)

- ROW scheduler: a better i/o scheduler to help our devices with their memories

- cpuquiet: manage tegra's clusters (G and LP), you can toggle them manually

- some optimizations to fight slow memory

Notes:

1- Yes they're here, u won't see them in the changelog cuz they were pushed directly to github, not to gerrit and then github.

2- You'll be able to enjoy these changes even more next days ;)
[Nexus 7 Original Development] todivefor:
Posted this in TWRP forum. Problem with TWRP restore cache and data F2FS. Anyone?
[Nexus 7 Original Development] fran_xda:
Thank you but I cannot find CPU options.
[Nexus 7 Original Development] Vnvjeep:
Instructions please? Not even seeing these under TricksterMod... :(
[Nexus 7 Original Development] linuxxxx:
CPU input boost:

echo 1 > /sys/module/cpu_input_boost/parameters/enabled

(Or 0 to disable)

CPUQuiet:

Low power cluster

echo "lp" > /sys/kernel/cluster/active

Normal

echo "G" > /sys/kernel/cluster/active
[Nexus 7 Original Development] dandemonic:
Thanks for this, and also for your ongoing work with our device, cpu boost made a noticeable improvement :thumbup:

Will this need to be done again after flashing new builds via updater or will it persist once set?

Nvm, it did, thanks again :sly:
[Nexus 7 Original Development] Vladimir2k9:
I am update to today build (17 may) and it already enabled.
[Nexus 7 Original Development] todivefor:
Can you explain what these do, specifically cpuquiet (tegra's cluster?
[Nexus 7 Original Development] agentfazexx:
5/18 is broken. SystemUI crashes. Don't flash it guys.

Edit: I think it's because of the a76/a77 kernels. 5/17 won't work with either. Going to try and flash 5/18 without a custom kernel.

Edit again: Flashing 5/18 without the kernel mentioned above works fine.
[Nexus 7 Original Development] pshadoww:
I am coming from Optpop and don't really want to wipe everything. So I wiped System and installed CM 12.1.

Now I am getting "com.android.phone has stopped" message.

Currently I freezed "Mobile Data" and "Phone" to stop FC message. But is there a better way to fix it?

Thanks guys!
[Nexus 7 Original Development] GtrCraft:
Yeah, a clean flash which is mandatory

Amazing battery and performance in 5/16 build. G cluster active and io boost enabled via trickstermod. Bfq scheduler.

[Nexus 7 Original Development] Craniotomy:
What kernel are you using with cm?
[Nexus 7 Original Development] fran_xda:
Me? I didn't change kernel.
[Nexus 7 Original Development] dabl8:
So, I upgraded again, from 1005 to 2405 and I get a similar memory leak. Didn't expect this to happen as both are based on 5.1. Since, it seems that nobody else gets this, my only thought is that it could be something with me having formatted to f2fs with official TWRP?!
[Nexus 7 Original Development] Reiven89:
How to set those two options via Trickstermod?

So latest nightlies have problems?
[Nexus 7 Original Development] fran_xda:
G cluster is set following the instructions some posts before. You can change io_is_busy parameter to 1 in trickster's governor settings. I think 16\5 nightly I better than next versions, I haven't tried this weekend versions though.
[Nexus 7 Original Development] Reiven89:
I am on the 1 june nightly and everything is working perfectly...unfortunately i dont have the paid version of Trickster so i cant modify those options
[Nexus 7 Original Development] fran_xda:
1 june nightly is the best since 16 may. You don't need paid version to modify that option.
[Nexus 7 Original Development] agentfazexx:
6/4 is broken. Just sits at the boot animation forever. Don't flash it.

Hi

I have a problem with restoring apps from previous installations.

There is a back arrow on top of done button so I can not confirm it. I tried quite a few gapps but it is probably CM related.

This Rom is seriously slow. I thought CM team are supposed to make these stuff uber faster vs stock

Memory leak

Just wondering if anyone has tried this or think this might benefit our Nexus 7 situation since it seems to reference lollipop in general?

http://www.androidauthority.com/galaxy-s6-memory-leak-reportedly-fixed-615651/

---------- Post added at 06:25 PM ---------- Previous post was at 06:22 PM ----------

Its the N7 hardware... It can't keep pace with the demands of lollipop... Google should have sunset this thing on kitkat 4.4.4... :(
[Nexus 7 Original Development] Ciex:
So the best bet is stay at cm 11, or whatever on the Android 4.4.4 now?
[Nexus 7 Original Development] decky006:
Try euphoria ROM. Running really well with latest bricked kernel. Find it on g+
[Nexus 7 Original Development] mikle_01:
What is the "bricked kernel"!? Inside the ROM or where to download!?

Is Xposed working? SELinux=Permissive (for Viper4Android)?

Am I the only one unable to install the 20th June nightly?
[Nexus 7 Original Development] luckyrumo:
The file ...0621... (which was built on June 20) works fine for me. (with CM OTA and TWRP)
[Nexus 7 Original Development] sgt. meow:
Yeah the 21st june nightly flashed fine for me. Forgot to mention.

Perhaps the date thing messed it up for me.

Running it now. Fluid. Smooth. But it eats battery like crazy.
[Nexus 7 Original Development] realadry:
Is it noticably faster than stock lollipop? Stock is extremely slow no matter what I try.
[Nexus 7 Original Development] luckyrumo:
There's no answer expect your own experiences... (depends on particular device and usage pattern)

Try using F2FS and reducing the number of apps, both helped me.
[Nexus 7 Original Development] sancamcal:
Hi all,

CM 12.1 made me love again my forgotten Nexus 7 2012! But i still feel that lollipop is for more hardware that i have. So, its possible to (like in other releases like CM 7 or 10.1) make publish the barebones list to make the most light version possible?

And what kind of CPU governor and I/O you think are the best combination?

Many thanks in advance!!
[Nexus 7 Original Development] Hawk600:
Plus one here, this ROM is just awesome and my 2012 N7 is pretty fast and responsive even if I still running the 50601 nightly. It just feels like a brand new tablet, thank you so much Devs!
[Nexus 7 Original Development] fran_xda:
Hi,

I have this issue since cm12: some menus are slow, for example go to Google play and tap comment section in any app: the new opened frame is kind of lacking of hw acceleration. Am I the only one? Thank you.
[Nexus 7 Original Development] Reiven89:
Did someone updated to the latest builds? improvements?
