Both, just to make sure. I tried community ones with PlayStation nav buttons and a dark-blue theme. When those didn't work I tried included blue nav and blue theme. None worked. Checked in SuperSU to cover my bases and Layers is granted root as it should be.

Edit - FWIW, the PlayStation softkeys are working on my G3. I don't like mentioning other ROMs in other dev's threads but if you want to know which one feel free to PM.

Edit 2 - Wait a sec....could this have something to do with running the F2FS version? I don't mind switching back to troubleshoot but there is a busy weekend ahead and it will be next week before I can get to it.
[Nexus 7 Android Development] iceandfire:
No problem. I'll have a look at it on my grouper. Thanks for reporting.
[Nexus 7 Android Development] FormeriPhoney:
I'm not interested in the f2fs version, so is it OK just to flash regularly in twrp?
[Nexus 7 Android Development] petenatas:
Anyone else have this problem?

When the tablet sits idle for a while, I have to hit the recent apps button twice for them to actually show up...
[Nexus 7 Android Development] zarac:
Yep, it happens to me too on all-F2FS beta5 version, and as far as I remember, it was happening on beta4 all-F2FS as well.
[Nexus 7 Android Development] samjam:
Just upgraded from stock lollipop hoping that this one won't run like treacle.

I find that Google play movies don't play... Probably a missing library
[Nexus 7 Android Development] HasH_BrowN:
a ?

Will I be able to change file system to F2FS in MultiRom in just this ROM or will the whole tablet need the file system changed? If it was previously posted, please excuse my ignorance and point me to the post. Thanks.
[Nexus 7 Android Development] JPHCCFC:
How's the f2fs performance? considering coming from freak lp as looks like that rom is dead but want too ensure best performance as nexus 7 can be unusable at times... F2fs gave it a new lease of life.
[Nexus 7 Android Development] samjam:
I didn't really understand the question. I used TWRP to reformat system cache data as F2FS
[Nexus 7 Android Development] Dai323:
Its solid for me. Probably the fastest Lollipop ROM have used for thr N7 until now, especially combined with Franco kernel. That being said, Lollipop still needs some work for the N7, so you will still see some lag here and there.
[Nexus 7 Android Development] barabangel:
I need on live wallpapers... please...
[Nexus 7 Android Development] JPHCCFC:
Have you tried freak f2fs? If so how did it compare?
[Nexus 7 Android Development] ichigo_kurosaki:
What is the workaround for the large icons? When i dirty flashed the 1/27 build over the 1/20 i didn't include reflashing gapps. And al SD o another annoying thing is that i tend to lose my multirom recovery after flashing the rom.
[Nexus 7 Android Development] seymour_butts:
I flashed the last build over January first days build, version f2fs, and tablet asks for a password. Can't login in. All lost?
[Nexus 7 Android Development] PapaMag:
The Slim Launcher is the reason for the large icons, load another launcher and you will be fine
[Nexus 7 Android Development] JPHCCFC:
Tried to install this ROM but all the gapps packages I tried to install failed with an error message insufficient space, tried micro and full!
[Nexus 7 Android Development] PapaMag:
Try the PA Gapps Modular Pico that's the one that I had success with finally
[Nexus 7 Android Development] seymour_butts:
mine does not go past the XENON HD logo... first boot, does not boot..

im assuming everything is ok since it let me install ROM ok (f2fs). Then installed pico gapps and ok. factory reset and reboot. It gets stuck :(
[Nexus 7 Android Development] sauravdante:
Have u flashed kernel?? with f2fs support..try mkernel a73, 1st flash rom then gapps then kernel..then it will be fine

Thnk me if i helped :)
[Nexus 7 Android Development] seymour_butts:
darn. went to try flash and lost acess to DATA. :( i can enter recovery but cant put/acess any files

edit1: went to recovery formated data. Now acessible. installed rom, gaps then kernel.. now ok
[Nexus 7 Android Development] HasH_BrowN:
What I mean is when I go into multirom fom recovery and select the Xenon rom can I change to F2FS for just this rom or does the whole tablet (all ROMs) need the file system changed? Will it cause instabilities with the other ROMs having different file system? Maybe I'm just not understanding. If your not sure, I'll go and post this question on the MultiRom thread. When I get an answer I'll post the answer here for others.
[Nexus 7 Android Development] brooker88:
Does this have theme provider? And does anyone know any dark themes for lollipop?
[Nexus 7 Android Development] mrpkarthik:
Current build has no theme engine. .CM theme engine has been replaced by RRO overlays.. check the change logs...:good:

There are many black cm12 themes available in play store...
[Nexus 7 Android Development] brooker88:
How do you flash another kernel? I tried phantom kernel but when I reboot phone its still a73. Didn't try Franco but im guessing that would be the same
[Nexus 7 Android Development] Dai323:
I just flashed in twrp and it worked on boot.
[Nexus 7 Android Development] brooker88:
Hmm strange, will try again. Thanks
[Nexus 7 Android Development] mrpkarthik:
I tried Franco kernel but cause . System FC :(... So again flashed Rom once
[Nexus 7 Android Development] FerrarisIV:
I am not sure, but wIth the last build i probably have problem using Chromecast app. It runs perfectly, but when i click on Disconnect the tablet freeze and I have to restart.

Someone have this problem?
[Nexus 7 Android Development] Rinoceros:
Did you have latest TWRP installed?

It should work with at least version 2.8.3.0 installed. Current version is 2.8.4.0
[Nexus 7 Android Development] brooker88:
Will try thanks, although kitkat seems to give few hour more battery than lp so I'm undecided
[Nexus 7 Android Development] petenatas:
I've installed beta 4 and 5 as well, both had the same bug
[Nexus 7 Android Development] RDDraco:
Best rom I have used for my nexus 7. Only aswell the worst cause I need to flash GAPPS every single update and set up all my google stuff again-.-.

Is this a known issue or is this on purpose?

edit: same goes for SuperSu, disapears as well after updating
[Nexus 7 Android Development] hokiealumnus:
I've had to do that on every AOSP ROM that I can remember. The only ROMs that come with gapps are stock-based, like the stock firmware on a phone or something. Some custom AOSP ROMs have SuoerSU built in, but most don't.
[Nexus 7 Android Development] RDDraco:
Well most roms where I had to install GAPPS remained having it even when i updated to a new version unless I did a full wipe. This one even without wipe removes GAPPS
[Nexus 7 Android Development] alexfiorani:
Hi, I just tried that (didn't have time to do it until now) but still no luck, the charging rate is extremely slow. I don't know what else to do, not even sure if it is worth buying a new USB port (not 100% sure if that will solve the issue) and fixing it here in brazil will be like 200 bucks, with that money I can buy a refurbished one. Anyway, I guess I'll try to mount it on my car and hope the car's USB charge rate is enough to keep the tablet charged so it has battery to be used when I need.

Thanks for the help.
[Nexus 7 Android Development] melp57:
Having problems with play store on this rom, doesn't install for some reason, and when I restore it from a backup, it loads, but always says there is a connection problem? Any ideas? Thanks
[Nexus 7 Android Development] RDDraco:
You have to reinstall GAPPS apperently cause GAPPS get removed after installing a new version even without wipe.
[Nexus 7 Android Development] melp57:
Thanks, but I have done that, still can't get play store to work.
[Nexus 7 Android Development] sauravdante:
Have u tried a new usb cable, i use a Bandridge one, try a new usb cable and do connect ur charger adapter to wall socket not in any hub. If not helped, u can try once more cleaning those copper contacts but this time dnt use paper use something hard and pin pointed and dont rub contacts horizontally, it can displace them, rub each contact carefully with a lil force vertically(same way contacts are in, up to down).
[Nexus 7 Android Development] alexfiorani:
I just bough the hole USB port + headphone jack board for 12 bucks and will replace it myself. I do think this will solve the problem. And yes, I tried different cables, chargers, etc. Thanks.
[Nexus 7 Android Development] kabell4:
Which kernels are functioning best with XenonHD?
[Nexus 7 Android Development] Teella:
I use lean kernel http://xdaforums.com/showthread.php?t=1950858

I used Oxydo for a bit, but found it got laggy and almost locked up at times, so I went back to lean kernel.
[Nexus 7 Android Development] Philosophre:
i know i don't need to update the supersu, but it would be nice. the binaries update keeps failing. normal and twrp.

is there updated binaries i can sideload?
[Nexus 7 Android Development] iceandfire:
You can flash the latest SuperSU v2.45 zip in recovery.
[Nexus 7 Android Development] Philosophre:
Well that's embarrassing. I trusted Google play store to install and update the latest. Apparently I was only 2.40 and didn't realize that 2.45 existed. Thanks.
[Nexus 7 Android Development] Salamin1:
Great rom, thanks! I still can't decide which kernel to use though
[Nexus 7 Android Development] dareino:
try em all....let the performance do the talkin'!

[Nexus 7 Android Development] trvbone:
I'm running lean kernel 5.2 currently because I was having issues with the tablet bogging down which always seems to be the case when I have M kernel on this old tablet.... Even when I was on freak slim LP rom.
[Nexus 7 Android Development] enriquejones666:
Franco just released his LP kernel (r81), give that a try. (Just make sure to get the F2FS version of his kernel if you're using the F2FS version of this ROM. It's posted in the thread, not in the OP)
[Nexus 7 Android Development] amcferrin90:
I couldn't get the ROM to install on Nexus 7 Tilapia. Cyanogenmod installed OK afterwards. Any thoughts?
[Nexus 7 Android Development] ichigo_kurosaki:
This ROM is so good. my only problem with this so far is the fact that, after flashing this ROM or dirtyflashing an update, it kills your recovery. i am on multirom and after each flash i have to reflash multirom and TWRP multirom.
[Nexus 7 Android Development] dareino:
Im on MR too and have Xenon as my secondary and have not had any issues that your described. I dirty flash if I can.

d
[Nexus 7 Android Development] gogol:
Anyone changed the low memory killer settings in the kernel?

If yes, would you please share the values?

Thanks
[Nexus 7 Android Development] RavenII:
I was running Slim F2FS for a while, and I decided it was too slow for me (the thing crawled actually) so I figured, I like stability, speed, AND butter....so why not try XenonHD...I liked it was fast as hell! Then I saw Dirty Unicorns...decided to try that....well, it didn't work, something about encrypted storage, blah blah blah, didn't feel like troubleshooting...did a full wipe to reinstall Xenon...and it just boot loops now...anyone have any idea? I'm running the F2FS version.

TL;DR

From a full wipe, I install only the F2FS XenonHD and it boot loops. Anyone experience this? Know what the solution is?
[Nexus 7 Android Development] nmugurel2003:
Flash an f2fs compatible kernel! Personally I like franco`s, but oxydo is not bad and faux also.
[Nexus 7 Android Development] PrizmaticSmoke:
When you flashed DU, it likely formatted your /system partition back to ext4, since it's not a ROM that natively supports F2FS.. Try formatting that partition again back to F2FS, then flashing the F2FS Xenon ROM again, and you should be good to go.
[Nexus 7 Android Development] zinko_pt:
Decreasing performance

The ROM does indeed look and feel fast for some time. After a couple of days (or hours, depending on the usage), it starts to lag and freeze. Occasional reboots also happens when it freezes.

The only (temporary) solution is to wipe cache/dalvik. That is quick, but the reboot is not. It optimizes all the apps as if I installed a new kernel or OS version.

Is it a 5.02LP common problem? I´ve read about this in other LP ROMs.

Also, CPU-Z reports 4x1.7GHz cores. Is it because of kernel definitions?

I suppose the battery performance is OK. I can´t really tell if 4.4.x performed better. But I do remember it depended a lot of the kernel and its settings.

Camera works just fine, and it seems a rare thing comparing to some other LP ROMs.

Thank you for making this ROM. Its my only Grouper ROM. But I wished it didn´t loose performance with the usage...
[Nexus 7 Android Development] hokiealumnus:
I get the same performance degradation. It's fine for a few days, then it boggs down. It's not horrible, but it's not nearly the same awesome performance as after a flash and installing TiBu apps. It's not the apps, because for a few days it flies along. Only after using it a while does it seem to slow down quite a bit. Battery usage on standby seems elevated as well. I'm on the F2FS build. I think I'm going to try going back to ext4 and try some other kernels to see if that helps. I really don't think it's the ROM, but more likely the kernel. I've seen folks mentioning other kernels helping, but they aren't (I don't think) compatible with f2fs.

Now to find the time to do it.... :silly:
[Nexus 7 Android Development] gogol:
Probably this LeanKernel v5.2?

http://xdaforums.com/showthread.php?t=1950858

I read it supports f2fs in the changelog, but I am not sure if it is fully support this ROM though.

I hope it is, because I want to try as well.
[Nexus 7 Android Development] hokiealumnus:
Awesome, thank you! I'll give that a try before switching away from F2FS. :good:
[Nexus 7 Android Development] Salamin1:
I'm using lean kernel (after Phantom and M) and my tablet seems faster now. Give it a try!
[Nexus 7 Android Development] cduced:
Install Process

I'm new to this ROM and a little confused on the install process. I'm assuming:

use newest twrp

backup current system

wipe system/cache/data

flash update-XenonHD-01-27-15-signed-grouper.zip

flash pa_gapps-modular-pico-5.0.1-RC4-20150208-signed.zip

reboot

If I decide to go with F2FS:

use newest twrp

backup current system

format system/cache/data to F2FS

flash update-XenonHD-01-27-15-signed-FULLF2FS-grouper.zip

flash pa_gapps-modular-pico-5.0.1-RC4-20150208-signed.zip

reboot

The main thing I'm not clear on is whether there is a kernel included in the ROM?

Thanks. -- Bud
[Nexus 7 Android Development] hokiealumnus:
Looks good to me. There is a kernel included with the ROM, yes. We're just talking about replacing it with Lean Kernel. That's not a requirement for flashing either version.

Edit - Just installed Lean Kernel 5.2. Cleared caches and booted up without issue. Will report back on my experience after using it for a while.
[Nexus 7 Android Development] zinko_pt:
It seems previous versions of LK5.2 don´t support F2FS. Just installed it. It is going through the agonizing optimization boot. :p

I will check performance and battery endurance and report back the synergy with this ROM. I will keep the kernel w/o OC, as close as stock as possible.

One more thing: I had to install Google launcher, since the default launcher (Slim?) makes big ass icons, while the description text is in normal size. Anyone else got this?
[Nexus 7 Android Development] Salamin1:
Yes, many people have reported the big icon issue. Just install another launcher!
[Nexus 7 Android Development] feelpt:
hi guys

i'm about to flash this rom and the suggested lean kernel. i have my device with f2fs. saw you guys talking about lean kernel and f2fs but didn't see any conclusion... does it work?

thanks in advance
[Nexus 7 Android Development] gogol:
YES, LeanKernel v5.2 does work with this ROM all f2fs version.

I am using it.

I think it's more or less the same compare to the M-Kernel a73. I got still occasional lag with LeanKernel. This morning was bad as I cannot even start an app. Rebooted. And most probably I will go back to M-Kernel.
[Nexus 7 Android Development] zinko_pt:
No lag after 12h. Battery performance seems better, but it´s too early to tell.
[Nexus 7 Android Development] bruce142:
When I converted the file format from ext4 to f2fs with the latest TWRP, I got the following issues with the f2fs version of this ROM or any f2fs ROM, I already wiped data (even Internal storage), cache, system and made sure that these are in f2fs partition and then after a reboot into recovery I installed update-XenonHD-01-27-15-signed-FULLF2FS-grouper.zip, pa_gapps-modular-pico-5.0.1-RC4-20150208-signed.zip (I can't install anything bigger than Pico GAPPS or I get a Insufficient system storage error), LeanKernelAllF2FS_s.zip (5.1) or I've also tried lk_grouper_lp-v5.2.zip followed by UPDATE-SuperSU-v2.45.zip. When I reboot my dad's Nexus 7 2012 (WiFi/Grouper) and get into the installation wizard after the step of selecting WiFi, the WiFi keeps randomly dropping out (and I have a very good WiFi reception as I'm near my router) which I never had when I was on the ext4 file format (stock Lollipop Rom or non-f2fs XenonHD) and when I want to replace the SlimLauncher with Google Now Launcher (Installed from the Play Store along with the required Google app) & I've deleted the SlimLauncher with ES File Explorer with Root turned on, I get an infinite boot loop even when clearing cache & dalvik cache (it then gets stuck on Starting Apps when Updating Android is over). I've tried clean reinstalling several times now and even tried other ROMS like Candy5 F2FS or SlimLP F2FS and even other F2FS kernels like Phantom Kernel or MKernel.
[Nexus 7 Android Development] zinko_pt:
It seems roughly the same battery wise. Probably a better standby energy management.

But performance is way better. No OC.
[Nexus 7 Android Development] RastaFATian:
It runs well with me too. Nice to see it flow smooth. :)
[Nexus 7 Android Development] Paden73:
Yeah, same here so far as well with Lean kernel.

Changed from Phantom.

Thanks for the recommendation ☺

Cheers, Paul
[Nexus 7 Android Development] hokiealumnus:
Same here...lean makes it run great, much better than m kernel. Battery life is similar but the experience is very much improved.
[Nexus 7 Android Development] psichokillah:
Can anyone post some tech info about battery life?

Standy, screen time, charge rate, etc? (in hours, minutes, days, etc)

It doesn't really help with "smooth battery, best battery, battery is great, battery x and y". I want to switch from stock but "battery smooth" freaks me. :o
[Nexus 7 Android Development] hokiealumnus:
Sorry, I don't actually use my tablet enough to come to any real conclusions; it plays very much second fiddle to my phone (a G3), which runs circles around the tablet's older hardware. I'll try to keep track and use it more to at least get you a screenshot worth your time.
[Nexus 7 Android Development] Bobbar:
I found this ROM (F2FS) to be a little glitchy.

-Recent apps would close as soon as it opened.

-Various graphical problems, when browsing in the background chooser, the bottom of the screen would become corrupt with flickering artifacts.

-The screen would randomly flicker on and off while locked, particularly after receiving a notification.

-Performance was very inconsistent.
[Nexus 7 Android Development] hokiealumnus:
FWIW [MENTION=3152067]iceandfire[/MENTION], I also have had the recent apps closing bug & notification flicker. Performance was remedied by switching to lean kernel. Never had any graphical problems like that described though.
[Nexus 7 Android Development] itm:
I'm just trying out this ROM, did a full wipe before flashing, and installed the gapps mini modular package. My problem is that after rebooting I'm getting a series of "Unfortunately, xxx has stopped" messages for all of the Google apps. Can anyone point me in the right direction to fix this?
[Nexus 7 Android Development] brunoavrocha:
my device doesn't even boot....stays on XENON HD animated screen forever....this has built in kernel or do i have to flash one?
[Nexus 7 Android Development] iceandfire:
Try a different gapps package. After a wipe of course.

Lollipop takes long to boot. What version have you flash f2fs or normal?
[Nexus 7 Android Development] brunoavrocha:
Normal version. I also have a note 3 and I know I have to wait... But more than 15 minutes for a 200mb rom? Do I have to flash a kernel?
[Nexus 7 Android Development] itm:
Actually I already tried two (both the modular and the mini modular) and got the same result. I guess I'll try the Nano Modular next, but I'm not optimistic....
[Nexus 7 Android Development] brunoavrocha:
this should boot without installing GAPPS right? and kernel?
[Nexus 7 Android Development] itm:
Ok so now I've tried gapps, modular, mini and micro (doing a full wipe between each) and get the same thing every time. The funny thing is, even if I do a full wipe without re-flashing any of the gapps packages, I still got these "Unfortunately, ..." errors after rebooting. The only way to get rid of the errors is to wipe and reflash the ROM, from where the whole problem simply starts all over again.

I'm getting the gapps files from the link in the 2nd post. Is that still valid?

???
[Nexus 7 Android Development] trvbone:
Pico modular was the only gapps I could get to work

Sent from my Nexus 6
[Nexus 7 Android Development] brunoavrocha:
For me this doesn't even boot. Going to give up on this
[Nexus 7 Android Development] hokiealumnus:
Are you flashing ext4 on f2fs partitions or vice versa. I've never had such trouble out of this ROM.

I would grab a fresh download of the ROM & gapps. Wipe everything, adb copy over the ROM & gapps, install & boot. Profit.
[Nexus 7 Android Development] FerrarisIV:
Can I ask if this rom is Rooted ?
[Nexus 7 Android Development] gogol:
Yes, it is ...

But, if you lost root, simply flash the latest version of SuperSU.

That's all, very simple.
[Nexus 7 Android Development] FerrarisIV:
Thanks for your reply.

I am asking this only because we have, in Italy, a service like Netflix to watch movies on Chromecast, they declare that rooted devices cannot work but i have XenonHD, with root, and it works... :)

ps: anyway, i remember that after last flash of the build (26.01.15) I had to flash SuperSu, too.
[Nexus 7 Android Development] iceandfire:
Updated to Stable v1.0

After months of beta releases here it is XenonHD Stable v1.0. Since last update which was about 20 days back a lot of new features have been introduced, tons of bugs squashed and lots of cleanup has been done all around the ROM. We have tried to eliminate almost all of the known bugs. With that said there might be a few if any and those will be fixed in the future releases. Thanks for sticking with us!

Leave feedback, press like or thanks and donate a coffee so that I can stay up in the future and improve this ROM. :)

PS: Changelog is available on our community page.
[Nexus 7 Android Development] hokiealumnus:
Awesome! I have no money to speak of for this, but I'll test and report back as best I can to help out. Thanks for your continued support of the OG Nexus 7!

What kernel does this ROM use? Also, which kernels y'all using?

You can also use LeanKernel.
