I started messing with trickster last night and wrote down changes. I'll try and get them posted later.
[Nexus 7 Android Development] SkOrPn:
Yeah, so long your using Interactive, row, and at least 1.5ghz, it works well. I don't even like running the minimum at 204, I prefer a min of 304 or what ever it is.
[Nexus 7 Android Development] dareino:
Ya I don think I have ever had probs running chrome on this rom or any other roms I run. Someone mentioned running adaway which I always load so I have no complaints. Also I am running full f2fs and my sys partition is at 19% and all is well. Running Freak,Validus and Xenon w/no major issues....

Is camera still not working?
[Nexus 7 Android Development] wrkerr:
Do you mean the navigation buttons, Back, Home, and Recent Apps? That's odd. I'd redownload and make sure you have the correct versions and most recent releases of TWRP, Freak-SlimLp, and Gapps. Maybe you've got an old release of something, a wrong version, a corrupted download, or are using a Gapps that is causing a problem. Links are the ones I used with success.

This last time I installed, I actually reformatted all of my partitions in TWRP, including internal storage, because I had a bunch of old images and zips in my /sdcard, and I wanted to start completely fresh.

You have an instruction how to format only data and cache? Want also to stay with system on ext4

Thank you for info

Is this for f2fs? I'm on f2fs sojust want to make sure before flash.
[Nexus 7 Android Development] ichigo_kurosaki:
What is the best kernel for this rom? Choices are the mkernel a74,leankernel and phantom kernel r2. And if anyone here is using any,i would like a feedback on performance and battery life.
[Nexus 7 Android Development] wrkerr:
Yep. I went all-f2fs for this update, and it's working great!

When I flash this ROM(alpha v1.0 2/26 and 3/5) , my system partition is ext4.. How are you getting all-f2fs up and running?

Here is a link that will get you up and running.

[Nexus 7 Android Development] wrkerr:
That link above is very clear, except you want to leave system as ext4 (the default). Otherwise, the process is the same.

Basically, use the "change file system" button in TWRP to format the partitions you want to the file system you want (only one at a time), then install ROM and Gapps normally. Freak-SlimLp is nice enough that it's only one zip now, which can handle any combination you give it (of ext4 and f2fs).
[Nexus 7 Android Development] SkOrPn:
Thanks for the link and help.

I'm amazed that TWRP has supported F2FS natively since June 5th 2014 and yet here in March 2015 people still do not know how to use it or that its right there already in their hands and so easy to figure out just by looking in the Recovery, lol...

---------- Post added at 07:38 PM ---------- Previous post was at 07:32 PM ----------

Yes, but people do not fully understand how or what F2FS or even what a file system is. F2FS is a massive write improvement over EXT4, like three times faster then EXT4 from what has been seen so far. However, the system is only a read partition, it only gets written to when you install a system app or when you format it. So when you do All-F2FS, all you are accomplishing is losing space, period. EXT4 has almost identical read performance to F2FS. So again all people are doing is throwing away space, but oh well that's ok with me. Cache and Data is written to constantly, so you definitely want that as F2FS, because that is where we get our performance improvement from in the first place. I love F2FS also and will never go back to EXT4 on a partition that gets written to constantly.

---------- Post added at 07:55 PM ---------- Previous post was at 07:38 PM ----------

Here you guys go. Check this out. What you want to remember is that Random Writes is the #1 most important aspect of a good performing OS, or in our case ROM. Look how EXT4 is not only as fast a F2FS in reading, but in most tests it beats F2FS in reading tests. But then look at the MASSIVE write improvements F2FS has over EXT4. So anyone who understands, knows that on partitions where you want write performance, then you also want F2FS, but on a partition that does nothing but getting read from, such as the System partition, then its more intelligent to go with EXT4 since it does a better job at Random and Sequential reading. Its not rocket science, its just fact.

http://xdaforums.com/showthread.php?t=2697069

The gist of it all:

Reading ONLY Partition (system) = EXT4 = You get same as or better reads, and more space to work with. Making this F2FS does one thing for you, it removes much needed space!

Read/Write Partitions (Cache & Data) = F2FS = You get same as, or slightly less read performance, but WAY WAY BETTER write performance, at the cost of about 16% space penalty.

Also remember, the less space you have the harder it is for the device to move data around. Its been like this since the existence of storage devices.

in new update with clean install navigation buttons, Back, Home, and Recent Apps NOT WORK... after 90 or 180 rotation, buttons work... but normal position tablet navigation buttons not work...
[Nexus 7 Android Development] techlifeweb:
I haven't seen that. What is your DPI set to? Settings > display > LCD density

Mine is 200 and the buttons work for me.
[Nexus 7 Android Development] SkOrPn:
It's working here perfectly. Just tried all four positions and no problem at all. Try Nova launcher instead.

[Nexus 7 Android Development] wrkerr:
No problems here either. I'm using the default launcher that comes with slimroms, SlimLauncher.
[Nexus 7 Android Development] FlatEric0074:
Here also no problem in whatever position I've tried... and this after dirty flash ?! Thanks for your amazing work!!!
[Nexus 7 Android Development] SkOrPn:
Lol, yeah I also Dirty Flashed... Maybe we should be Dirty flashing more often then ;)
[Nexus 7 Android Development] wmatheney:
SkOrPn, Thanks for the detailed explanation. I've never used F2FS but want to give it a try. I can see how to convert to it in TWRP but if I leave System as EXT4 and change data and cache to F2FS, what version of ROM would I install if I did? EXT4 or F2FS? Please pardon me for the F2FS newbie question. Not new to rooting and flashing but just never dug into F2FS. Thanks.
[Nexus 7 Android Development] wrkerr:
The recent alpha releases can handle either. There is just one ROM image, and it can be used for any combination of f2fs and ext4 partitions.
[Nexus 7 Android Development] SkOrPn:
Just flash the most recent version. The ext4 version is for ext4 only and thus would not support formatting data and cache to f2fs. But the F2FS version has always supported both file systems. When a developer "adds" support for F2FS he doesn't remove ext4 support. So all F2FS Roms support any combination of the two file systems.

In twrp there is a place to convert the partitions to what ever you like. Do so just before flashing the ROM.

Hello,

Since the update from February, my N7 on his dock can't go out from a Daydream screen without being locked.

Before : touch the screen to close Daydream

Now : touch the screen to turn off the screen

Is this change from a commit of the Slim Team, from you or just a mistake? :/

Hi

Flashed slimlp 2 days ago but my tablet is not with me now

May I know if the rom supports

1. usb-otg?

2. a wifi adapter via usb otg?
[Nexus 7 Android Development] ayoraider07:
okay... I've done all-f2fs before, when I flash alpha 0.91 20141220-1511, using twrp 2.8.5.1, it successfully installs, system, cache and data are f2fs after installing .zip. When I've tried to install either alpha 1.0 20150226 or 0305, it installs fine, except at the end I get the message "unmount of /system failed; no such volume" and system partition is set to ext4 ... honestly, I don't think I care anymore, it seems that ext4 system performs great, but I think I had less lag moments with f2fs system
[Nexus 7 Android Development] pjcanales:
Can't wait for next release since Google release 5.1.
[Nexus 7 Android Development] techlifeweb:
That happened to me once. I didn't even leave the install menu in TWRP, just flashed again right away without wiping and didn't get any errors

I would like to see a benchmark to check the real difference with stock and with cyanogenn mod 12
[Nexus 7 Android Development] GalaticStryder:
Can't even compare, also benchmarks doesn't supply smoothness and stability.

Guys already using this post could you feedback me on this build: http://renderserver.net/devs/SaberSunset/grouper/

It's my first time compiling for a tablet, I don't own N7 anymore but I compiled it anyways.

It's compiled with Uber toolchains and optimized a bit as well.

[MENTION=5373714]freak_97[/MENTION] sorry for posting it on your thread, if you mind I can remove it.
[Nexus 7 Android Development] luismg:
I've just done a clean install, is it really smoother or just animations are 4 times forced faster?
[Nexus 7 Android Development] IFLPI:
For the lags IMO lowmemory killer values matters a lot. In kernel auditor I always set the 2 first values to about 115 MB. What are your experience in that matter [MENTION=228985]Scorpion[/MENTION] [MENTION=373710]others[/MENTION] ?
[Nexus 7 Android Development] SkOrPn:
It's mostly the animations and the right choice of toolchain and optimizations.

Yes I agree low memory is one of the worst things for this device. It also seems to take a dump when multiple tasks occur even in the background. I now have about 44 percent free space in system and it seems to stay smooth and fast so long no multitasking occurs in the background lol. When I enable wifi its really bad for about half a minute or so and completely useless until it finishes what ever its doing, syncing etc.

[Nexus 7 Android Development] IFLPI:
I might be wrong but I remember N7 as a snappy device when I bought it. It was on Jellybean 4.1 I think. I had many apps, over 100, many working in the background. I was using Facebook app and the Viral, window pop-ups video, and it was working nicely. There were lags while writing to internal, eg during Google Play automatic apps update, it lagged a lot, so I just disabled this in the beggining. But for the most time it was ok during heavy tasks. So maybe we should stay at Jellybean 4,1 ROMs for the Nexus 7. This ROM is nice od course, but maybe it cant handle lollipop very well in general. BTW, hang on guys, cause 5,1 is comming :D
[Nexus 7 Android Development] SkOrPn:
Its never been fast for me and I've had it since November 2012. Its a quad core, so of course it can handle LP. Its just that LP wasn't so optimized yet and using a new runtime on a device with crappy slow nand. ART is having its growing pains, but is clearly superior. We just need a newer more modern Kernel, and LP to mature some more. Well see what 5.1 has to offer but it may be a short wait for 3rd party devs to get the new code working.
[Nexus 7 Android Development] Mikey:
Doesn't the new google playservices apk keep the devices awake at all times, killing the battery???

Is everyone using Lean Kernel? I can't decide if I like it or M-Kernel.

It currently going through the Google retoration process.

5.1 is so awesome. My nexus 7 2012 is snappy again. it's as snappy as ipad mini. Multitasking is flawless. No more annoying memory leak bug. Overall my tab is now as fast as when i bought it more than a year ago.:D gaming is superb. Ram management is also superb.
[Nexus 7 Android Development] pellajl:
Jury still out on 5.1....

Used Google Maps once and noticed a degradation in responsiveness already.

We'll see what happens with a couple of days use.
[Nexus 7 Android Development] IFLPI:
I personally dont see any significant difference between them. Now I use M-kernel. But with a new build I wont use any different than the original one. Just to check.

And I hope we'll see the 5.1 build soon from our dev :) Google says they fixed the memory leak finally
[Nexus 7 Android Development] pellajl:
Only time will tell if 5.1 fixes the memory management issues.

Where can I find the change log for 5.1?

changelog for the noobs out there [emoji23] [emoji6]

The next update will be based on 5.1 but it will take a bit longer than usual because I will wait for the slim team they merge 5.1 into their repos and then I have to check if my commits are still compatible with the new source.

I also have to do more for school the next 2 or 3 weeks.

I'll wright my last exams for this school year in most of my subjects[emoji106] [emoji106] [emoji106]

[Nexus 7 Android Development] thistimearound:
I haven't been able to from Freak without massive lag stuttering. When it's not stuttering it's blazing fast, but unfortunately it hands for quite some time, even with developer optimizations and only flashing micro GApps. With 5.1 after a couple days it's WAY more responsive overall. Sure, the processing speed isn't as quick as Freak in high gear, but the lag is considerably lower (though not entirely void), and doesn't last long unless I'm pushing for many very intensive tasks.

[Nexus 7 Android Development] SkOrPn:
Well 5.1 sucks here big time. SUCKS SUCKS SUCKS!!! Some of my most important apps do not work at all no matter how I install them. Its like 5.1 put up a solid steel+brick wall preventing them from even installing. The normal dpi of 200 on this device does NOT look normal any more. I would have to experiment just to get back what 200 used to look like. Anything that uses the network, seems to take twice as long to load now. Now Chrome takes twice the time to load web pages, and is no longer stable as it used to be on freak. Google did NOT restore the apps data so now I have dozens and dozens of apps to restore data on or to sign in, when it should have restored it automatically. Its NOT any faster and even with animations turned completely off its considerably slower then freaks. None of my TRDS RRO layers are working, I have to go back to the EXTREMELY ugly and painful to look at white themes. The list goes on and on of things that are just wrong, even the kernels do not have the correct settings for this device. This device MUST have overclocking to work proper. NO THANKS! Back to reality, I need a working device, otherwise this thing is completely useless to me now. Going to wait for the Slim team to figure out how to implement 5.1 code and then hope freak can fix that to my liking. lol, the ONLY thing I did notice that has improved is "shut down" and "reboot" seems quicker to me. I like that since I reboot religiously every morning. Oh well wasted 18 hours of my time trying 5.1, and now I will go back to what is working for me.

I am happy I made a backup of a truly good setup. So, do NOT forget that, always use TWRP backup feature just in case you do not like a new ROM system. As soon as this thing charges back to 100% I am going back into TWRP as fast as I can and restoring the latest freak SlimLP and getting back my functioning device.

GREAT, I just discovered 5.1 has completely corrupted my file system on the data partition, now I can't install anything or restore anything. Even a Factory Wipe no longer works.
[Nexus 7 Android Development] adomol:
Did you try formatting? If that doesn't work... with the amount of ROM testing we do on these old N7's it's just a matter of time till that NAND takes a swandive off a cliff though.
[Nexus 7 Android Development] SkOrPn:
I got it. Thanks to WUGs, TWRP, OTG and some time. I managed to move what was important, namely my TWRP backup and my latest TitaniumBackup folder off to my dedicated flash drive using TWRP file manager and OTG. Then I used WUGs latest stuff to put it completely back to stock. Once it was back to stock everything, I just re-flashed TWRP, converted data and cache back to f2fs, and used the flash drive to put both the backups back onto the internal sdcard partition. TWRP was then finally successful restoring the last backup from yesterday, yay.

Might have to wait a bit longer for me to trust 5.1 again. lol
[Nexus 7 Android Development] dareino:
uggh..I think it just wacked my system as well...Im on multirom and I d/l the multirom's Devs stock Lp posted on his page...I was able to install it boot up but after installing latest 5.1 gapps, I cant even get to recovery. TWRP comes up but then it goes back to google screen.

Not how I want to spend my free time

[Nexus 7 Android Development] SkOrPn:
Yeah, I should have mentioned that PAgapps might have caused everything to go hay wire. I used the nano package, but it kept failing. So I then downloaded the latest banks at euroskank and that installed just fine. After booting up, which was also just fine, things just did not work correctly, it took like three attempts just to get the damn setup to connect to the wifi. Clearly 5.1 isn't quite stable, and I tried twice with two different versions of it.

Going to wait a wee bit longer, for at least Slim to release it, or one of the other major releases such as CM, Omni or Carbon, but id rather just wait for Slim and Freak. For now I need to realize that what I have is working perfectly as-is.

Running Stock Lollipop 5.1

Been running Stock and rooted Android 5.1 now for a couple of days now and I must say it is much better than 5.02.

I installed the ROM using WugFresh Nexus Root tool kit. One thing to note, Busybox V1.23.1 seems to have an issue with 5.1. It says it is installed yet apps like Trickster MOD says Busybox is not installed.

I have been using Google Chrome and Maps which used to kill 5.02 and these now seem to be running reasonably well. Facebook seems to be running OK also. I also have all applications previously loaded in the latest SlimLP ROM. The camera also works! :)

Sometimes there is a small delay before the tablet responds but I wouldn't call it laggy.

When I speak of delay, you must remember my tablet is now running:

All partitions are ext4 format

CPU running at 1200 MHz max

It quite obvious there were some serious issues under the hood of 5.0 and 5.002 and Google have gone some way in resolving these issues. Not sure why Google risked it reputation by releasing 5.0 and 5.002 with all the issues. It must have been something to do with the release of the iPhone 6 (marketing madness.

Bootup time is around 90 seconds which isn't too bad.

I believe 5.1 is a great platform to use as a base for further optimisation.

I am looking forward to a slimmed down version being release in due coarse.

Finally, I have attached a screenshot of Android Assistant Monitoring page.
[Nexus 7 Android Development] ichigo_kurosaki:
Well not the case for me. 5.1 finally solved the problems with previous versions including that annoying memory leak bug. I can now play my ram intensive games on lollipop like rr3. I dunno but for a bit comparison (no offense to you and freak :)) i dunno what's wrong with slimlp but on xenonhd (another lollipop rom i tried) i can play rr3 there for a while before it lags like hell. But now on 5.1 memory issues are nonexistent but yeah i am excited what slim team and freak can do to make this even faster.
[Nexus 7 Android Development] IFLPI:
I flashed PA lollipop ROM with leankernel. Its extremely fast and snappy. But RR3 reboots the tablet, so its buggy a bit. But fast

Now I try CM rom, but im using it to short to say anything. But its a nice rom as well

[Nexus 7 Android Development] dictionary:
Zero idea what went wrong for you. 5.1 has been a blessing to my tablet. Haven't had any issues at all. In fact, it's fixed pretty much every fault my tablet had. Can't wait for custom ROMs based on this. Would love some more options, but can deal with stock for now.
[Nexus 7 Android Development] SkOrPn:
Yeah I don't know either, the MD5 was good but nothing that I need to work actually worked. But that's OK it only took a few hours of time to fix it. I will be trying again soon enough once everything works proper.
[Nexus 7 Android Development] IFLPI:
Something is wrong with my tablet. I flashed some roms and kernels, and now its getting hot and not responsive after couple of seconds after boot up. It reboots then. I turned off media scanner to fix that, but I suspect that data partition or some data is corrupted. In the recovery I tried to repair /data partition but it came with an error. Other partitions it fixed without an error. Are there any way to check or fix the internal? Or just flash factory img to wipe everything? This thing happens on 3 different roms, and each of them boots only wit a lean kernel. Its strange that fSlim LP doesnt boot without custom kernel? It supports f2fs for data and cache...
