thank you i have fixed it hopefully, redownload at same link
[Nexus 7 Original Development] parrotgeek1:
Please redownload I think haveged is fixed now
[Nexus 7 Original Development] parrotgeek1:
Don't do it yet, it's still being tested
[Nexus 7 Original Development] bangsergio:
Redownloaded and installed but haveged still don't run, postboot.sh not giving output.

[Nexus 7 Original Development] federico72:
Installed without error on 6.0.1.

Did not reboot automatically. The max CPU is still 1300 mhz.

Since I trim every day I didn't see much difference but I need to test it on another N7 @ home where I use a BT headset that is shuttering like hell.

Postboot.sh has no output.
[Nexus 7 Original Development] parrotgeek1:
I set max cpu 1300 mhz to fix a battery problem.

But is storage related lag fixed? (Try opening stuff while installing an app) And is multitasking better?

Haveged should be running, but doesn't launch for an unknown reason.
[Nexus 7 Original Development] parrotgeek1:
no output is ok but is storage related lag fixed? (Try opening stuff while installing an app) And is multitasking better?

to debug haveged

please change the >/dev/null of haveged in postboot to >/data/haveged.txt

and send me haveged.txt
[Nexus 7 Original Development] federico72:
I didn't see much difference since is a fresh new install. Just time will tell. Different case for the other N7 I have, probably there I will see if it make difference or not. Anyway I would like to test an overclocked version! :D
[Nexus 7 Original Development] parrotgeek1:
1)Are you using ext4 or f2fs? i have not optimized f2fs yet so use ext4 for most speed increase.

2) I will never OC, this mod is only for ram/storage fix
[Nexus 7 Original Development] federico72:
Then if you don't want to overclock or if is not good for f2fs edit the original post.
[Nexus 7 Original Development] parrotgeek1:
There are going to be 2 versions of this mod

1 for stock 5.1.1 with debloat OC stagefright etc

and 1 for every rom 4.1-6.0.1 (this beta)

The universal one will be in a new topic after beta is done

f2fs works with the stock version but not universal (yet)
[Nexus 7 Original Development] federico72:
Ok. Mind to tell me why overclock is not applicable on a mod version for MM? I mean, there is an effective bug/issue or just coding problem? Just curious, because N7 NEEDS overclock to play well...

OP is busy, so I hacked it myself. Look for another of my post after the one you found on what to do.
[Nexus 7 Original Development] 123x:
I replaced my grouper's USB board, but it didn't help. The dock is too expensive in relation,so I guess I'll just have to live with it and probably eventually buy a new tablet. Not from Asus though!
[Nexus 7 Original Development] parrotgeek1:
I have made a new version that should work on EVERY rom even 7.0 without editing the script!

download it at the same link as in OP

to check if it works

open terminal emulator

type

su

getprop parrotmod.running

if it says "yes" then it works
[Nexus 7 Original Development] zard:
Tried on talipia on nAOSProm (Nouget) but nothing was returned in Terminal Emulator.
[Nexus 7 Original Development] parrotgeek1:
ughhhhhhh

try this

go to /system/su.d

and in the 2 hack fixes edit them

after the #! line, add touch /data/12345

then save andreboot

and tell me if /data/12345 exists
[Nexus 7 Original Development] zard:
Nope.

BTW, I've flashed your mod that I modified by removing exert statement, whether that affects anything?
[Nexus 7 Original Development] adstraylight:
I tried this on the new Carbon Rom, and it seems to work partially:

All the prop changes get applied and the zram is set up, but it looks like none of the /sys parameters are affected, so the minfree stuff etc. stay at defaults,

I thought this might be a busybox thing, so redirected the script to use my bb installation (busybox on rails) in /system/bin, but no joy. I can however make those changes either directly via root explorer's text editor, or via Kernel Auditor, so it seems BB is working on the device.

Hope this makes sense!
[Nexus 7 Original Development] parrotgeek1:
i think it is selinux, i will try to set selinux permissive when the script starts and enforcing when it ends
[Nexus 7 Original Development] slbp180:
Tried flashing this on my Nexus 7 with PA 5.1 rom, and when I try turning it on, I get the upgrading apps message, then it gets stuck on "starting apps" until the battery dies.
[Nexus 7 Original Development] ho0o0o11111:
Carbon, 7.0

No problem here.

Thanks for the update.
[Nexus 7 Original Development] adstraylight:
Even though the getprop test says so, I think you'll find that the minfree values, adj values, and read ahead value don't tally with those in the script. If you manually set them after booting, the ROM gets even better.....the other variables that are meant to be set happen by happy coincidence to be the ROM's defaults anyway, and all the changes made by the script's setprop commands come into affect as well.

[MENTION=5723969]parrotgeek1[/MENTION], would an apk for those of us (most of us) that are rooted be the way to go?

Edit: Also, the ZRAM is set up, with its swappiness values etc, but not initialised, so you need a kernel management app to do this (well I do anyway ?).
[Nexus 7 Original Development] giannibat:
Thanks, I'll give a try!

Just wanted to see thanks for the speed up for my Nexus 7. It was pretty much useless until I installed this fix.

Keep up the great work.

On the getprop parrotmod.running terminal returns nothing. Is this normal or the script isn't running?
[Nexus 7 Original Development] laikj:
I installed rom ([ROM] 6.0 Android MarshMallow Pure AOSP for Google Nexus 7 2012 WIFI by vocoderism) on nexus 7 grouper along with gapps, supersu. It works ok and BT is working which i could connect my BT keyboard to it. However, after I install parrotmod (ParrotMod_Grouper_Universal_2016-10-14_19.33.56.zip). The BT stop working and pop up "Unfortunately, Bluetooth Share had stopped".

May I know where I can go from here to fix the BT so that it can be use?

Thanks in advance.
[Nexus 7 Original Development] adstraylight:
I would say that the script has not executed, as it should begin by setting the running property to "yes".
[Nexus 7 Original Development] eNVy:
Here is another trick to speed up the device. I have installed Cm13 on grouper having data and cache in f2fs.
[Nexus 7 Original Development] ThurstonX:
I was on an older version (ParrotMod_Grouper_Universal_2016-05-26_16.22.40) until yesterday. Before upgrading I ran the getprop command and got nothing in the term. The old method confirmed parrotmod was running. getprop worked fine after upgrading, so it seems a re-flash for the OP might be in order.
[Nexus 7 Original Development] adstraylight:
Oh I think I see, the running prop was only added in the last version, so it wouldn't have worked before you upgraded..
[Nexus 7 Original Development] MiamXD:
Just to be sure and not destroy my setup again: It is ok to install "ParrotMod_Grouper_Universal_2016-10-14_19.33.56" on the Nexus 7 3g Tilapia, right?

I think it would be great to rename the package or include something about this in the first post, the 3g Nexus is only mentioned once (because of tethering, in the feature list).
[Nexus 7 Original Development] giannibat:
So what's wrong with the carbonrom settings? I'm trying to get the rom usable, but it's sluggish at all.
[Nexus 7 Original Development] sancamcal:
Hi all,

in which of all ROMs published on XDA works Parrot MOD? I have CM13 but im thinking to move to other (6.0.1 or 7.) because that one doesnt have more development. In the other hand, what do u think that is best, in performance?

Thanks in advance

[Nexus 7 Original Development] giannibat:
Is this rom working out of the box with ParrotMod or it needs some adjustments?
[Nexus 7 Original Development] brockn1985:
It's working out of the Box. Follow the instructions in the 3.4 Kernel-Thread. Reboot sys afterwards. Root, and so on. Then Reboot to recovery, flash parrot mod and su 2.71. Reboot. Done.
[Nexus 7 Original Development] MiamXD:
To answer my own question: the grouper package works on tilapia. It runs great now

A comment about that topic in the OP would still be nice
[Nexus 7 Original Development] albysprx:
Is this mod detected from safetynet? thanks
[Nexus 7 Original Development] xxfwmxx:
If shouldn't
[Nexus 7 Original Development] broomer68:
The mod itself will not trigger safety net, but the root will be detected unless you systemless rooted and installed busybox using magisk and turned it off for the time needing to run safety net.

[Nexus 7 Original Development] Jim Barr:
Did a "dirty upgrade" last night on my Nexus 7 2012 from SlimKat 9.0 to 9.1, then flashed parrotmod and the SuperSU update. I have to say that I'm absolutely stunned by the performance improvements. I did the same with my wife's nexus 7 2012. The test will come tomorrow morning when she fires up Google News. It is always a long, LONG wait. I hope she sees a noticeable difference, particularly with swapping apps, and loading Web pages in Chrome.

Kudos to the developers on this!
[Nexus 7 Original Development] wech71:
Incredible!

Incredible!

Before I stumbled over this thread, I was about to throw out my first gen nexus 7 because of the massive lags, but now it runs just as new!

I used last official stock Android 5.1.1 and wugfresh to backup, unlock, root and flash parrotmod.

Restored the backup and installed all apps again and it works like a charm!
[Nexus 7 Original Development] Paddy's:
random reboots

Hi, i read this in the first page : "or just leave your tablet on overnight (on silent) instead of turning it off, so it can automatically trim."

Does the tables reboot to do the automatic trim or should the automatic trim happen without reboot?

I am asking this because i am experiencing random reboots even with the tablet on silent mode and one time while i was using chrome. Do you have random reboots too?

I have a tilapia 32gb with latest parrotmod and latest slimkat rom by LordNerevar.

Also i have all F2FS partitions . Thanks
[Nexus 7 Original Development] giannibat:
Trim operations should perform silently during recharge and standby, but without rebooting. Maybe some unstable apps.
[Nexus 7 Original Development] parrotgeek1:
i guess I'll make an apk. I just wish chainfire would fix su.d
[Nexus 7 Original Development] adstraylight:
Well I'm currently using a script based on yours running via an init.d emulator app that pretty much achieves what I want it to.

I've cut the zram disksize down to 200MB, as it seems to give 7.1 less lag, and I don't use the wifi changes as they seemed to make the connection less reliable within the confines of my domestic setup. Ironically I think this might be due to the enhanced signal strength making it harder for the ROM to decide which AP to connect to, as the effect was a constant switching back and forth in some areas of my house.

Maybe an apk that allows some measure of control over the parameters and implementation? Apologies if I've just given you more to think about! ?

Edit: oh yes, and do you remnember this?

service call SurfaceFlinger 1009 i32 1

I wanted to try it in nougat, but keep getting an error in terminal:

CANNOT LINK EXECUTABLE "service": cannot locate symbol "XzUnpacker_Construct" referenced by "/system/lib/libunwind.so"...

Parrot mod

I want to install Perot mod onto my 2012 nexus 7 but do not know how to do the following 'PLEASE disable IO scheduler/RAM/read ahead tweaks in kernel apps'. Tried lots of googling with no success, please advise. Also, you say, Don't use Universal_Test unless I tell you to., the charging fix seems useless to me because I never use earphones on the tablet, so what is the next step?
[Nexus 7 Original Development] adstraylight:
All it is saying is if you have already set up tweaks then turn them off, so if you have not done anything like this then you can just install the mod. Just flash the universal version of the mod (+ SuperSU if you haven't already) and enjoy ?
[Nexus 7 Original Development] brentoma589:
Hi all, recently decided to revitalize my long disregarded 2012 Nexus 7 8gb. I read in a few places that 4.1.2 would be faster than the horrible 5.1.1 so I reverted to 4.1.2 and it already seems a lot faster. I believe I read elsewhere on XDA that 4.3.x and above roms might slow down my tablet more than 4.1.2. So my question is, what can I expect to be faster, 4.1.2 stock rooted or 4.3, 4.4, or even 5.1.1 with ParrotMod? Thanks

I agree, just flashed SlimKat 4.4.4 with small gapps and ParrotMod, fast and proper. Only complaint is Bluetooth doesn't seem to work well with it. Not sure what is at fault.

Can you use this mod with cynogenmod cm 12.1-20151117-SNAPSHOT-YOG7DAO1KA-grouper + f2fs ? If yes, how do you install? just normally or you do something different?
[Nexus 7 Original Development] synwars:
Just installed this on top of DirtyUnicorn AOSP 6.0.1 and I'm reporting all is well. Bluetooth works in this version, storage is fast and OS is snappy. Just a little lag in the transitions and animations (GUI) when there are multiple downloads and 2-3 simultaneous processes going on, but it seems unavoidable for anything above 4.4.4. But don't get me wrong, I'm speaking of milliseconds type lag, it is still much snappier than OEM.

Anyone any answers/advice to this post please? Got the same problems/results on all the current 7.1 ROMs myself! I am clearly missing something and just don't know what! Pick any 7.1 ROM of your choice (Grouper) to help me please.

I am an "old fart" but a bit of baby talk would appear to be quite permissible and what will be understood by me if you could please!
[Nexus 7 Original Development] hakkalugi:
I could be horribly mistaken, but I thought Parrotmod was only intended for Lollipop, not marshmallow or nought. I wouldn't expect a lollipop based kernel to work with a nought ROM.

Hope this helps...

I am using a normal nexus 7 2012 not rooted and I have no experience whatsoever about this kind of stuff. Is there any detailed version of above procedure? I really want to get my nexus7 back. Many thanks in advance.

Hi,

Just installed this mod, my Nexus is quite faster now but it keeps optimizing all the apps at every boot.

I rooted the Nexus via NRT (and the Nexus was wiped while unlocking the bootloader) because Kingroot failed and everything seems right except this optimization issue.

I tried to wike dalvik cache and cache via TWRP but it was unuseful.

Parrot status seems ok (checked as suggested with a terminal app)

Any suggestions? Thank you
[Nexus 7 Original Development] flintash:
in my case it was caused by Gaaps. if you go for it, you have to delete /system and flash different gaaps. In my case pa_gapps worked well, open-gapps caused optimization on every reboot.

I recommend omitting old OS versions in combination with this "mod" and instead installing a fresh and new Android 7. AndDiSa's builds comprise the "ParrotMod" settings; as far as I understood they are included in the kernel.
