Sounds like your using the Performance governor, which would put all cores on all the time and make the device fast but at the cost of lots of battery.
[Nexus 7 Android Development] IFLPI:
I knew someone will say that. Nope :) There is really sometning wrong here. Tablet is warm even while screen is off. I think I must flash via NRT to check if that helps. Or wipe media ... I dont even have performance governor. Slim lp doesnt boot with Mkernel suddenly, only with lean kernel, and sometimes flashing lean kernel causes error. Really strange things with this tablet happens. Even if i got performance gov - when I turn on the media acaner, it becames nor responsive and reboots after 5-15 seconds
[Nexus 7 Android Development] SkOrPn:
Yeah, go back to full stock via NRT. Mine also gets warm, but I use Interactive and it only gets warm during use. All other times its cool to the touch.

The Bluetooth streaming is a bit choppy and the bluetooth-headset does not automatically reconnect. Is there a bug in the Bluetooth? Clean install with f2fs.

hi there, just flashed the latest NON f2fs and it runs really nice... just one thing :

i get bootloop at slimkat logo when changing to ART... already tried 3-4 times, waiting 15+ minutes and no success... any idea of whats causing this?

thanks in advance
[Nexus 7 Android Development] :
Did you use xposed framework ? Maybe that the cause. Personally I didn't use the tablet since a week but I will search the charger and check it
[Nexus 7 Android Development] feelpt:
nope, no xposed here

thanks
[Nexus 7 Android Development] :
I have the same issue ... I can't solve the problem already wiped my kk source . I'm sorry ...

[Nexus 7 Android Development] carlfinity:
Forgive my ignorance, is this F2FS format compatible?
[Nexus 7 Android Development] :
No f2fs suppport now but i will do it today
[Nexus 7 Android Development] SkOrPn:
SlimLP + ALL-F2FS + a73 is utterly amazing. Best setup so far.

Happy Thanksgiving to all who celebrate it.
[Nexus 7 Android Development] litemintx:
thanks for this rom, working great as SkOrPn suggests SlimLP + ALL-F2FS + a73.

I just wonder is anyone experiencing sudden close of the Facebook App?
[Nexus 7 Android Development] JohnBonchie:
What is this 'ALL-F2FS' and 'a73'??
[Nexus 7 Android Development] carlfinity:
It has to do with the last updates of Facebook. Not rom related.

---------- Post added at 12:35 AM ---------- Previous post was at 12:32 AM ----------

I couldn't agree more! I love this rom! You converted it yourself to All F2FS? I tried flashing it to my F2FS partitions but it reverted the system to EXT4. I guess I should wait for the proper file.

Hi, I know this is off-topic, but do you think it's a good bang for the buck if I bought one of these similar servers on ebay?

Just thinking of running Linux on it, possibly Linux server distro. Thank you for any info you might have.

Dell PowerEdge R610 2x XEON Hex-Core X5650 2.66GHZ 2x 300GB 10k SAS 32GB

http://www.ebay.com/itm/251835661696?ssPageName=STRK:MESINDXX:IT&_trksid=p3984.m1436.l2649
[Nexus 7 Android Development] SkOrPn:
I dont know much about servers, or their associated costs. I just know I got a 6 core, HEXA core with 12 threads running at 4ghz and did so for $75 bucks. It may be a few year old chip, but still its not like the newer stuff at ten times the cost is a massive upgrade from Westmere. A new Hexa core running at my speeds would cost a LOT LOT more, not counting needing a completely new Motherboard. Only if you need a new system, or the new supporting tech such as USB 3.1 is it worth spending that amount. For me I am ok with waiting for the Skylake platform.

OH, and by the way, Ubuntu MATE runs amazing on this, and so did Ubuntu Server, and so does the new Windows 10 build 10041 :good:
[Nexus 7 Android Development] papajonpizza:
Thank you very much for your quick reply! My problem is I don't have many of the other parts; so I'll need to purchase motherboard, RAM , cooling, PSU (I think I have one but I have to look for it, lol), case? (although I don't even mind having it out in the open :) ), hard drive, and when I add all of them up; this server deal is just about the same price? I'm looking at more "barebones" server for sale, then just buying the RAM and other stuff, which I could save $100 or even $200.

I won't have the ability to overclock, but it's ok as I'm just playing around with stuff and trying to find a reason to utilize a super-speed machine :) Maybe try to compile some custom ROM or something :D
[Nexus 7 Android Development] pride007.2012:
Go to stock before it damages your tablet. I think there is some compatibility issue with ROM and kernel.

Sent from my Nexus 7
[Nexus 7 Android Development] ichigo_kurosaki:
Sorry for quoting you but maybe you can help me. I had been on stock 5.1 since it got out..rooted and using my favorite multirom twrp setup. Since freak hasn't had a 5.1 build yet (excited for it tho) i decided to.try rastapop since out of the 3 roms i am watching (rasta, slim, xenonhd) rasta got to 5.1 first. But when i encountered a problem decided to revert to stock..and to my.horror i couldn't restore it. Halfway thru system partition restore it fails. Dunno why..i made a successful backup prior.:'(
[Nexus 7 Android Development] Reiven89:
There is a possibility that camera will work in this rom or i have to look somewhere else for that? Thank you
[Nexus 7 Android Development] SkOrPn:
Rastapop completely corrupted my device, not once but twice in a row. Thankfully I managed to get my TWRP backup off the device and onto a flash drive. I then used NRT and flashed it back to stock. I then flashed the latest TWRP and restored the device using the backup. It worked perfectly.

Yeah I cant wait for freaks 5.1 but I think he is waiting on the SlimLP team.

Sent from my Nexus 7
[Nexus 7 Android Development] IFLPI:
Quick question:

Does NRT restore ext4 filesystem of the /data /cache during IMG flash ?
[Nexus 7 Android Development] SkOrPn:
That depends on what your doing with NRT doesnt it? I mean if your flashing a rom with f2fs partitions, then it should just flash the image. If your flashing back to stock N7, then its back to stock N7. That question can only be answered by your intentions for using NRT. NRT has many many functions. And the image setup dictates the file system used, not the app used to flash it.
[Nexus 7 Android Development] goldeneagle1972:
Agreed
[Nexus 7 Android Development] IFLPI:
Ok, I meant stock IMG. So the answear is yes.
[Nexus 7 Android Development] IFLPI:
Ok, it booted now. Jest the NRT didnt extract the IMG properly. But finally I got the 5.1
[Nexus 7 Android Development] goldeneagle1972:
Freak-SlimLP is 5.0.2
[Nexus 7 Android Development] SkOrPn:
Yeah, if you have a stock 5.1 image, then yes Google used EXT4 on all the partitions. I think only one device is using F2FS for its stock file system and that is the Nexus 9 I think. Or so I think I read... Samsung might be using it some day soon, but that depends if they can get F2FS out of beta status.
[Nexus 7 Android Development] IFLPI:
I think I saw sth on the web that moto X (maybe some other Motorolas too) uses f2fs.
[Nexus 7 Android Development] wrkerr:
Wikipedia confirms that most of the recent Motorola phones are indeed running f2fs. I didn't know that. Lol. That must be why they have such great performance, despite being relatively modestly spec'd. My first gen Moto X is still very snappy.

Great call supporting f2fs, freak_97. Can't wait for the next release!
[Nexus 7 Android Development] SkOrPn:
Yeah, I updated my Ubuntu distro to 3.19.2 just so I could have the latest F2FS commits, however I have yet to format anything to F2FS. This file system came to Nexus 7 2012 first simply because it has such terrible performing nand already and it drastically needed something, to at least improve the write speeds. I wasn't aware Motorola was adopting it with F2FS still considered not fully stable yet. Interesting
[Nexus 7 Android Development] TheXorg:
Is this normal? http://youtu.be/ZTpAw4WjSQk
[Nexus 7 Android Development] wrkerr:
I don't notice anything abnormal. There are settings for the batter indicator in Settings , Interface, if that's what you had a question about.
[Nexus 7 Android Development] TheXorg:
I mean that the Charging indicator is blinking
[Nexus 7 Android Development] wrkerr:
Yeah, mine blinks too.
[Nexus 7 Android Development] pettigrew95:
Sorry if this was answered already but I couldn't find it in the thread. My google play store keeps saying "Check your connection and try again" I click retry and it keeps doing the same thing. I googled it and tried removing my google account and re-adding. Also tried clearing cache and data and force stopping the play store, google play services, and download manager. Any ideas is greatly appreciated, thanks! Oh btw, it was a totally clean flash of the ROM.
[Nexus 7 Android Development] SkOrPn:
Are you using the Layers RRO themeing and perhaps TRDS PlayStore? I had that problem until I uninstalled the dark play store theme.
[Nexus 7 Android Development] pettigrew95:
No themes at all.
[Nexus 7 Android Development] cptsashimi:
I think that happens when the play services is updating. I've had it happen several times and I just exit out and wait a minute and it works when I go back in.

That's just my guess but seems plausible.
[Nexus 7 Android Development] duckredbeard:
Is this a Grouper ROM? Any issues with installing this ROM on a N7 that is 3G, but without a SIM card? We have no intentions on putting it on a mobile network, just using it as wifi. I don't want the mobile part of it continuously searching for signal.
[Nexus 7 Android Development] goldeneagle1972:
You can basically fix that by going to all apps and clearing data on play store and google services framework then reboot so they can start up properly again
[Nexus 7 Android Development] pettigrew95:
I tried that and it didn't work
[Nexus 7 Android Development] BlueKnightedDragon:
When I get this issue I delete one of the google accounts I have set up and then add it again and it fixes it. I hope this helps you :D
[Nexus 7 Android Development] duckredbeard:
Just flashed this ROM, going through the app reinstallation now. Bluetooth will not stay off. Anyone see this before? I had it on an OmniROM on my TF700 but it wasn't a Lollipop issue, resolved with a kernel flash.
[Nexus 7 Android Development] Kant73:
Thanks !

Your ROM is just amazing !

My N7 was just useless due to a lot of big lags but thanks to this ROM, I can use it again =D

So thanks for your great job [MENTION=5373714]freak_97[/MENTION] and I can't wait to see the next update with theme engine, TRDS and maybe Android 5.1 =D
[Nexus 7 Android Development] catchjeff:
This is an amazing ROM you have here. This is my first f2fs ROM and my N2 2012 is as if I just booted it up for the first time. Super fast on everything. Thank you for this.

It´s Ok

The Status:

Slim realeased the 5.1 repos but they have to work to get the old features working again. This can take a little bit longer.

I joined optipop another coustom rom ...today I tried to build for this device but I get updater script errors.

I don´t know how complicartet it is to fix it.

I have holydays for two weeks now but I´m working in this time.. Honestly I don´t know how long it takes to update this rom.

Anyway happy easter everyone I hope you have a good time :D
[Nexus 7 Android Development] pellajl:

[Nexus 7 Android Development] qx876:
Hey, can anyome help me with kernel settings? I have version 20150305/ leankernel installed.

The only thing I changed with trickstermod was upping the freq to 1500. My device has some problems though with apps like feedly/chrome/hearthstone.

Any tips how to tune that kernel some more?
[Nexus 7 Android Development] Leonhan:
I believe lean kernel's max frequency is only limited to 1500. He made it that way so that it saves more battery. If you want to OC it up a bit more, try oxydo or M-Kernel.
[Nexus 7 Android Development] sladeslayer:
I take it that you have installed it on 3G device. How did you proceed? Do I need to edit any text file before flashing this on tilapia. Please comment.

Thanks in advance.
[Nexus 7 Android Development] DXU76:
Thank you for your time and effort creating this ROM. I have no $$ to buy a new tablet but after applying this ROM I have my tablet back! Its so fast and been stable so far. It's like falling in love all over again with my N7.

[Nexus 7 Android Development] joeshmoe666:
F2FS

I already had system, cache and data all formated to F2fs. In your instructions you say "format cache and data for f2fs" . Should I leave everything formated like it is? Or do I need to change system?

.... and thanks for your work.
[Nexus 7 Android Development] wrkerr:
There is debate over if it is better to format /system to F2FS or leave it as ext4. I've tried it both ways, and both are fast... tbh I can't tell a significant difference. To be clear though, /cache and /data perform much, much better with F2FS.

That being said, the majority seem to think /system is better off left as ext4, so that's the recommendation. It will work either way though.

If you want to follow the recommendation, reformat /system to ext4. Wipe all partitions, then flash the ROM, then flash GAPPS, and enjoy the best 2012 N7 ROM there is.
[Nexus 7 Android Development] pellajl:
As stated in previous posts, the System area is never written to and therefore there is no performance advantage in having the System area formatted to f2fs. In fact you can adversely impact performance because f2fs reduces the amount of available System memory.

f2fs gives you increased performance when writing to the Data and Cache areas of memory.

The optimum configuration is to have the System memory formated to ext4 and Data and Cache areas formatted to f2fs.

I cannot get either 0.9 or 0.91 version ROM to install. I am getting an "Error executing updater binary in zip" error. I changed /cache and /Data to F2FS through TWRP 2.8.6.

[Nexus 7 Android Development] BL4CK_92:

Yes I followed the steps for a clean flash.

Wipe system, Data, cache, and Dalvik. Format cache and Data. Try to install zip, get an error.
[Nexus 7 Android Development] BL4CK_92:
disable zip verification, maybe?
[Nexus 7 Android Development] DirknJirkn13:
Already disabled. Also tried using CWM, same result. I'm going to say it has to do with the zip file.
[Nexus 7 Android Development] DirknJirkn13:
I found my issue. I did not realize there is a 1.0 version since it is not on the site linked to the downloads in the first post. I was able to get that flashed through TWRP. I was also able to get 0.91 flashed through ADB.

Is 1.0 the latest version from March 5th? Not sure whether the title means March 5th or May 3rd.
[Nexus 7 Android Development] noldar:
Ok for me too on 1.0, f2fs, actually booting.
