Just flashed the 07/26 build last night, so far it's working very well. Does anyone know of an alternate kernel that's compatible with the ROM...I want to play around with overclocking and undervolting?
[Nexus 7 Android Development] harry_fine:
Asked the same question three posts back. No reply.
[Nexus 7 Android Development] hochoch:
Installed last night. Runs OK, a little laggy and slow down but for my kid to watch YouTube and Netflix its fine. Tried several other kernels and couldn't get any to boot but stock. Xposed and viper4android installed fine tho which is great. Thanks for keeping our groupers up to date!
[Nexus 7 Android Development] pellajl:
The XenonHD-07-26-15-signed-grouper.zip version supports f2fs.
[Nexus 7 Android Development] iceandfire:

Updated core repositories with upstream AOSP and CM. Tons of changes in this build. Refer to the changelog for complete list of changes.

Please wipe before flashing this build.

Press like or thanks, leave feedback and donate if you can :)
[Nexus 7 Android Development] BaldaX42:
In download now. Thanks for the job man!

Someone can advise me a kernel for this rom?

Sorry for bad english :)
[Nexus 7 Android Development] KawaiiAurora:
I would suggest M Kernel ^^ Remember to underclock it to 1.3Ghz!
[Nexus 7 Android Development] BaldaX42:
Thanks man!

I can't install the gapps, when i flash it it said: "Installer will not exit... Error Code: 64".

I try to flash the "x86 5.1 stock 8 August 2015" and "ARM version"...
[Nexus 7 Android Development] KawaiiAurora:
I'm a girl lol :3

Go to opengapps and select ARM, 5.1 and pico. Pico works best on older devices ^^ Install the other google apps you may need via the Play Store ^^
[Nexus 7 Android Development] martinko23:
Hey guys, i'm on this rom since i got my N6 but i can't use any OTG cable, it won't recognize any of my USB sticks..

I tried to format them in any format (fat32, NTFS,...) and still nothing.

I'd like to know if this rom support native otg and if no what can i do to be able to use my otg cable ?

thanks
[Nexus 7 Android Development] BaldaX42:
My god i'dont know it ahahah :)

Now it works, thanks a lot :)
[Nexus 7 Android Development] Sage:
Which kernel does this use and can you over clock? thanks
[Nexus 7 Android Development] KawaiiAurora:
I'm not sure if it's stock or franco. You shouldn't overclock as it will make your nexus 7 unstable... The only overclocking you should attempt is 1.5GHz with M Kernel. It works pretty well but there is some extra heating up.
[Nexus 7 Android Development] pellajl:
Tried to perform a factory reset from the Settings menu. The tablet rebooted and then it attempted to enter Recovery mode.

The Teamwin screen appears and then periodically blanks in what appears to be a loop.

Has anyone experienced this?
[Nexus 7 Android Development] KawaiiAurora:
I haven't but maybe you should try reflashing TWRP via fastboot. I'm not sure if you can rename the xenon hd zip as update.zip and flash it via fastboot but it sounds like a faulty recovery.
[Nexus 7 Android Development] snooffy:
Oh my god. This ROM is smooth and crisp as anything I came across with for the Grouper. Some ROMs are fast, but they lag time to time, but this one? I feel like I bought a brand new tablet! Thanks a lot!

One question though:

As I'm sharing the tablet with my little daughter, I'm using a restricted profile for her. She's used to just tap on her photo to get to it. With this ROM I'm not able to change the picture on a restricted user account. Any thoughts? Tried to Google it 1st but no luck... :/ I cannot replicate the problem on cm12 with the same apps and same kind of settings.

Edit: Using a different app (i.e. google photo app) for cropping the picture solves this if somebody would wonder.

In your experience, does this ROM works better on F2FS or EXT4?
[Nexus 7 Android Development] amitabhr:
I get an error when trying to change DATA partition to F2FS , system and cache converted to F2FS without any error.

Can I flash the F2FS version with Data ext4 ?
[Nexus 7 Android Development] Tmzdroid:
1.3GHz is the best speed for mkernel on my Nexus 7
[Nexus 7 Android Development] pellajl:
I believe you can but you are better off with f2fs.

Have you tried to install the latest Teamwin recovery software?

Did you wipe the partition before trying to convert it to f2fs?
[Nexus 7 Android Development] amitabhr:
Thanks.

Ok, it worked after a few reboots/flash and formatted data to f2fs.

Next problem was the Google Play Services error coming up repeatedly. Will wipe and reflash again.
[Nexus 7 Android Development] snooffy:
I had the google play constantly crashing, it was driving me mad. No matter which LP ROM I've tried it kept crashing. Then I came accross a post somewhere saying that this is caused by an old recovery version. Did not think this could affect it, but tried it anyway and the problem was gone.

So if you have a lots of Google play crashes, even after fresh flash, make sure you have the latest recovery image installed before you go any further.
[Nexus 7 Android Development] amitabhr:
gapps 5.1 arm stock/full/mini & pico all give an error "this version is for 5.1.X"

Edit:

Should I try 5.0 gapps ?

Edit 2:

Strangely, the 5.0 gapps pico installed.
[Nexus 7 Android Development] iceandfire:
Updated to Stable 2.0 Build 8

Updated with some new stuff like three finger swipe gesture to take a screenshot, ability to open heads up notifications in floating mode, ability to disable lockscreen visualizer, completely redone file manager, battery bar for navigation bar, etc. Fixed bugs like the latest stagefright vulnerability, fixes to floating mode, etc. Google apps are now backed up while flashing the ROM so no more need to apply the gapps after flashing the ROM starting with this update.

Kernel updated with battery/performance improving changes, etc.

Much more changes that I don't actually remember.

Please leave a feedback, press like or thanks and donate if you can.

Do not let the thread die and get buried under.
[Nexus 7 Android Development] Protibus:
Great Rom. Brought back new life to my Nexus 7. Best Rom out there, smooth, snappy with lots of all the right tweaks. I can't say thanks enough. Tried flashing using the gapps backup but had to flash gapps separately again to get Google login and playstore working correctly for restore of apps and settings.

Great job

Sent from my SM-G920V
[Nexus 7 Android Development] kidstretch:
Great rom, battery life is super!

Downloaded and installed the version of 23 August 2015, there's something wrong with the colours on the screen!

Also the voice wakeup is not working :(
[Nexus 7 Android Development] tboooe:
First of all thank you to the dev for this ROM. I am wondering if there will be an F2FS version of the latest update? I only see a version from back in February.

Thank you again.

EDIT...went back a few pages and it looks like recent versions of this ROM is already compatible with F2FS so there is no need for a special version anymore.
[Nexus 7 Android Development] tboooe:
Just got the F2FS version of this ROM installed on my Nexus 7 (hand me down from my daughter). I am impressed with how much more responsive this tablet is. Prior to this ROM, running Lollipop the N7 was very sluggish. The customization options are also great! Thank you Dev!
[Nexus 7 Android Development] pellajl:
There is no separate f2fs version any more.

Which version of this ROM did you install?
[Nexus 7 Android Development] tboooe:
Sorry for not being more clear. I meant I converted my tablet to F2FS. I installed the latest version of the Rom dated 8-20-15
[Nexus 7 Android Development] kalafior12:
Latest version is allf2fs compatibile?
[Nexus 7 Android Development] tboooe:
Yes...my N7 is working great after the ROM upgrade. To be honest I do not know how much of the improvement is because of the ROM or the change to F2FS. Either way, I am very happy.
[Nexus 7 Android Development] Dadud:
i dont know what it is, but with this rom, and any of the roms I've tried, the tablet likes to hang and lockup whenever i install more than 20 apps on it. is this everyone elses experience as well?
[Nexus 7 Android Development] arozer:
Hi folks,

I have used or updated my Nexus 7 since, I think, like 4.4 update.

Would this be a good rom to jump on to? (I know that's subjective but what I'm asking more or less is if I'll have any issues jumping from 4.4 to 5.1.1).

Another option would be to wait for Android M. But I think it would be nice to familiarize myself with Android 5+ in the meantime.
[Nexus 7 Android Development] tboooe:
I dont have this issue. How much memory do you have left?

I didnt have any issues making this jump with this ROM. When I updated my N7 with the stock 5.1.1, it became so sluggish that it was unusable which was why my daughter let me have it. (I actually traded her an IPAD 2 I had laying around for this!).
[Nexus 7 Android Development] dookie23:
What kernel do you recommend if I want to F2FS on /cache and /data?
[Nexus 7 Android Development] dookie23:
I wasn't able to get Lean Kernel to work with this rom either. I previously tried installing Lean Kernel with the stock 5.1.1. /cache worked fine with f2fs but not with /data. This could be an issue with Lean Kernel tho.
[Nexus 7 Android Development] DUSTYBOODA:
Can anyone tell me how to get full f2fs working on this rom? Data and cache are f2fs but when I try to convert system and reboot it stays on the Google logo? Or is it best to have just data and cache f2fs? I Just got a cheap nexus 7 2012 version recently but stock is slow so I found this rom and heard about f2fs can dramatically speed things up :P
[Nexus 7 Android Development] shawnbrennan55:
I don't believe any Grouper 5.1.1 ROMs support F2FS on the system partition.
[Nexus 7 Android Development] pellajl:
Firstly, it is the Kernel that provides support for f2fs and it is possible to use f2fs on the system partition. Not sure why you are getting the Google logo....

However, using f2fs on the system partition is not recommended for a couple of reasons:

1. f2fs only increases Write performance. It does nothing (or negligible) for Read performance. During nornsl operation, nothing is ever written the System partition so there is no point using f2fs on the System partition.

2. File storage on a f2fs partition is far less efficient. The usable memory is actually reduced using f2fs. The Nexus 7 (2012) only has 1MB of memory and under low memory conditions, tablet performance takes a big hit. You can't afford the loss of usable memory on the Nexus 7 (2012) tablet.

I hope that has answered your question.
[Nexus 7 Android Development] DUSTYBOODA:
Ah I see, thanks for the info

So its best to leave f2fs to cache and data then, the rom seem fast and fluid anyway with ext4 on system so I'm happy with it :D but which kernel would you recommend? I think im still on the stock 5.1.1 kernel as I only got the tablet 2 days ago and I haven't flashed a kernel yet, just this rom unless this rom comes with a kernel to?
[Nexus 7 Android Development] dimiar:
Which kernel is compatible with this Rom? I have tried franks lean Lego bricked but without success. Tablet can't boot . am I doing something wrong?
[Nexus 7 Android Development] pellajl:
I am using the kernel that comes with the ROM. Haven't tried any other kernel so I can't help you.
[Nexus 7 Android Development] dookie23:
I can also confirm that the kernel that comes with the ROM works well with F2FS for /data and /cache. I don't know any other kernel that works for /data and /cache. The latest Lean Kernel (v5.1) only works with /cache. I tried to contact the developer on this issue but I haven't got any replies.
[Nexus 7 Android Development] topet2k12001:
Hi Friends,

Just to provide feedback.

The ROM is responsive, and seems to be fast. I have been switching and trying out different custom ROMs for the Nexus 7 (2012) due to the "slowness issue" upon updating to Lollipop. So far, this seems to be the best one - well, also because it can support F2FS. My son uses the tablet and as we know, kids will install a ton of apps. I will restore my Titanium Backup copy of all the apps and will monitor so that I can compare (again, I'm running the ROM in F2FS - cache and data partitions only).

That said, I am also confirming that I did not use a different kernel when I flashed this ROM (after converting cache and data partitions to F2FS). I don't know if it's placebo (i.e. effect of F2FS or if the ROM in itself is fast) - I will know after I restore all the apps/games and will revert back.

Great job! :)

One question though: does the included kernel of this ROM allow for Multiboot (i.e. it has kexec path applied)?

Extra: I followed the steps here for converting to F2FS...but instead of the ROM being recommended in the said article, I used XenonHD:

click me!
[Nexus 7 Android Development] grotesque02:
Hi!

I want try this rom, f2fs version.

I see in OP the release is old, no one new?
[Nexus 7 Android Development] pellajl:
You need to igone the link to the f2fs version. This is a hangover from when there were separate versions. Not sure why the link hasn't been deleted.

Whilst it is not specically stated, all the latest releases support f2fs.
[Nexus 7 Android Development] drshafi:
Hi to all, today i flashed slimkat all f2fs rom on my N7. My query is can i flash this f2fs rom on my N7? If yes then what is the flashing instructions?
[Nexus 7 Android Development] iceandfire:
Starting this weekends weeklies, XenonHD will have OTA support. If you find any issues with your updater or links, please don't hesitate to bring it to my attention. Thank you as always for your continued support of XenonHD﻿.
[Nexus 7 Android Development] grusta:
Thank you for your support !

i'm using your rom on ext4, basic usage because of my broken screen. No lags, as far as I can tell. :)

Awesome. Thank you for the continued development of this ROM.
[Nexus 7 Android Development] Cyda:
Since updating to lollipop my Nexus 7 was running like a dog, all stalling and lagging, so after reading good things about this ROM I thought I'd give it a try, and man what a difference! I just wanted to say thanks for a great ROM, it has given my nexus 7 a new lease of life and I think it will be running this ROM for the rest of its life. Cheers!

Help with RAM

Hi folks! I am looking for help with RAM management for my Grouper N7. I notice that after a while my N7 gets sluggish and slow to respond to screen input especially if I use apps like Chrome or GReader. I think the culprit is RAM which usually at around 70-75%. I use apps like Clean Master to clear the RAM but it doesnt really do much. Even after I close all apps and clear the memory RAM usage still is around 60%. I am wondering if there is anything I can do the Kernel settings or Build.prop file to help with RAM management?

Thank you in advance.

BTW, anyone use the latest weekly? I am about to download and try it myself.
[Nexus 7 Android Development] hokiealumnus:
One tip is that basically you need to stop using Chrome on the N7. It has gotten to be too much of a resource hog for this older tablet. I'd recommend switching to Dolphin.

Can't speak to GReader though, sorry.
[Nexus 7 Android Development] shawnbrennan55:
Chrome is definitely a no go on Grouper. I've recently switched to Opera on all of my devices. It has a nice interface on Android, Linux, and Windows & syncs across all platforms as good or better than Chrome.

Also be sure to set all animations to 0.5x and set Force GPU Rendering to ON in developer options. This tends to help with overall snappiness.
[Nexus 7 Android Development] tboooe:
Thank you for the suggestions guys.

What about overall RAM management. I see some setting in LMK (low memory killer) that I can tweak but frankly I no idea what all the numbers mean. I've used Greenify, AutoStarts and TitaniumBackup to keep as many system apps from starting and using RAM but its still at over 50% even after a fresh reboot.

EDIT: I selected Aggressive in the LMK settings and it seems to really help. Maybe others can try as well and report their findings?
[Nexus 7 Android Development] dookie23:
[MENTION=4290049]tboooe[/MENTION]: Take a look at the following post. I have included some settings in the build.prop and these seem to work pretty well.

[Nexus 7 Android Development] JNasty:
Can anyone recommend a kernel other than the default one?
[Nexus 7 Android Development] jazzespresso:
[MENTION=3152067]iceandfire[/MENTION]

why?

Getting "error: 70" while installing GAPPS. The error says “Insufficient storage space available in System partition”

as developer of this ROM, would you make recommendation or fix for this?

I know you would probably going to recommend to get gapps minimal pico version, but why system partition soo small?

also,

i can't also set static wallpaper on this ROM, is it me or this is a bug?
[Nexus 7 Android Development] spidey88:

[Nexus 7 Android Development] pss34:
Almost all roms supporting f2fs now. This one have universal zip.
[Nexus 7 Android Development] rekd0514:
I can't get the system partition to stay on f2fs. Once I flash the ROM it switches only that to ext4? Am I doing something wrong? I even tried to convert the ROM with the app on the play store with no luck.
[Nexus 7 Android Development] rester555:
Is this team going to continue with Marshmallow for Grouper?
[Nexus 7 Android Development] pellajl:
The Nexus 7 has only 1GB of system memory and therefore very restrictive. Can't do anything about the system partition size.

You need to install the smallest GAPPS package you can find and the manually install the Google apps you want after the ROM installation is complete.

If this is the first time you are installing this ROM, you should perform a complete wipe of all partitions in Recovery before you atempt to install this ROM.
[Nexus 7 Android Development] pellajl:
New version of Layer Manager appeared in Google Play. It downloads, starts to update but the installation fails.

Any one had the same issue on the latest ROM?
[Nexus 7 Android Development] iceandfire:
Haven't decided yet but probably yes.

Delete/uninstall the current version and install it from Play Store. It's not the ROM but the app itself.
[Nexus 7 Android Development] pss34:
It woul be great to have M on our device. I hope :)
[Nexus 7 Android Development] pellajl:
[MENTION=3152067]iceandfire[/MENTION] - tried that. The ROM only allows me to uninstall the previous updates. I cannot unis tall it completely. I have disabled Layers.

Is there any way of forcing the complete uninstall of the Layers app?
[Nexus 7 Android Development] FirePsych:
Try Titanium Backup or Rom Toolbox. Admittedly, I have not tried either myself yet.
[Nexus 7 Android Development] Madcat8686:
The way I did it was with an app that will uninstall system apps (root enabled). I used this one:

https://play.google.com/store/apps/details?id=com.lb.app_manager&hl=en

Once installed, you have to go into settings and enable root system app uninstall. You then tell the app to uninstall and then reboot for the changes to take effect.

I was able to flash this ROM without issue, but the Gapps are a different story. I've tried a few different builds and have received various errors in recovery when installing.
