Will do. All seems to be working now. Thanks for your help.
[Nexus 7 Original Development] :
The SuperSU check on latest parrotmod 2204 doesn't allow me to flash / update this version, due to not having the latest SuperSU version installed. I'm a bit puzzled, I had SuperSU beta 2.71 installed and tested it afterwards with stable 2.65. No success.

Any idea?
[Nexus 7 Original Development] bolidew:
Can the Stable Version 2016-04-22 flashed on top of older version?

Thanks.
[Nexus 7 Original Development] dilorenzo:
Same here! Always says SuperSu is not present
[Nexus 7 Original Development] Ammar_Hamdan:
I flashed Pure nexus rom and disable journaling zip at the end flashed your mod and super su..

Should I reflash the whole rom.. Or just enable journaling?
[Nexus 7 Original Development] parrotgeek1:
Just enable journaling
[Nexus 7 Original Development] parrotgeek1:
Oh yeah, I forgot to account for systemless root. I'll just remove the check and assume people aren't dumb
[Nexus 7 Original Development] parrotgeek1:
yes
[Nexus 7 Original Development] parrotgeek1:
Stable Version 2016-04-23

Remove SuperSU check
[Nexus 7 Original Development] suku_patel_22:
Does the mod work on the latest marshmallow pure Nexus ROM? Or Re we suppose to use only on lollipop ROM's?
[Nexus 7 Original Development] dilorenzo:
Just flashed 4/21 and it worked

Are there hug differences between 21 and 23?
[Nexus 7 Original Development] parrotgeek1:
It works on PN, yes
[Nexus 7 Original Development] parrotgeek1:
Yes, especially battery and sound quality. See the 4/22 change log. (23 is identical to 22, but it installs correctly)
[Nexus 7 Original Development] :
Thx!

Using a clean CM13, with pico gapps. Holy fudge this brings so much life back into it! I was on stock 5.1 and even opening the settings was a crawl. Everything is soooooo much better, I cannot thank you enough!

Would you get any speedup applying your mod to other devices such as the Nexus 7 2013?
[Nexus 7 Original Development] adstraylight:
I just deleted this line from the build.prop of Pure Nexus, at parrotgeek's suggestion, and does seem to make a difference after a reboot ?

ro.sys.fw.bg_apps_limit=6

I left the other one as he said it might be actually helping.
[Nexus 7 Original Development] lotte67890:
What a great advantage! Runs so smooth and flawless! Thank you so much!
[Nexus 7 Original Development] parrotgeek1:
1) youre welcome

2) no, it's device specific but i own a flo so i could make it later but i have the ghost touch problem so i hate using it
[Nexus 7 Original Development] parrotgeek1:
the next version of parrotmod will add # to the beginning of ro.sys.fw.bg_apps_limit (to comment it out) when you install it
[Nexus 7 Original Development] professorpasta:
Right, I mean would the general underlying idea be advantageous for any other device?
[Nexus 7 Original Development] parrotgeek1:
Yes, devices where slow flash memory is the bottleneck. Also it could be good for single/dual core devices which spend too much "energy" on disk I/O. It's open source and feel free to fork it and mess with it.
[Nexus 7 Original Development] nereis:
I already started playing with a very stripped down version of the script on old single core devices, Galaxy S has MoviNand and HTC One V has Toshiba I think, but both slow. So far 0kb parrotmod cfq seems not too different from 4kb readahead with row, but still faster than 128kb or 512kb readahead.
[Nexus 7 Original Development] parrotgeek1:
If your build.prop has a huge number of duplicate entries at the end, sorry. It will be fixed in the next version too.
[Nexus 7 Original Development] brokenarray:
Hey all I tried to look throughout this forum and cannot figure out why I cannot flash the parrotmod. I flashed CM13, supersu, gapps pico. Then I tried to flash the parrotmod but it fails because it says "this is not a 2012 nexus 7". Any ways to fix. Thanks for the help.

I installed this on my grouper with the latest version of chroma rom, and it works just totally awesome :) I can't believe that this works so smooth, it's really impressive

Could someone test this mod with a 5.1.1 rom? I'm on 6.0.1 and bt audio with games like real racing 3 is shuttering like hell... I tested 4 different MM ROMs and is always the same. With normal audio like when listening music or watching videos my bt headset works fine.

Hey, can someone guide me? Im on 5.1.1 rooted, stock rom,franco kernel. Can i just put parrotmod file and gapps on flashify and flash them or is it more complicated? pls help.
[Nexus 7 Original Development] pjcanales:
Hello I need help. I'm on pure nexus on grouper and what I did was install parrotmod, then after that installed from twrp I installed supersu. And it said everything installed correctly, so I chose to reboot and now it's been 30 and still on boot screen. Can someone please help me.
[Nexus 7 Original Development] wokawoka:
guys, I have tried to read the old posts but I still have to understand if at the moment the mod works on tilapia as well.

Can I flash it on my nesus 7 2012 3G?

Thank you!
[Nexus 7 Original Development] adeelraj:
restore ur backup and then try to flash parrotmod alone not with supersu

yes u can

as it doesnt break any 3g or gsm parametrr
[Nexus 7 Original Development] wokawoka:
I've just tried to flash the zip via TWRP on some different KK roms I've installed via multirom on my tilapia but I always get the error: "ParrotMod requires at least 8MB of free space on the sistem partition, refusing to install. ...." .

Could it be the fact that I'm using multirom the problem?

Thanks again
[Nexus 7 Original Development] pjcanales:
i recently installed but notice it take a long time to boot up from a restart or turn table off and on maybe 10 minutes or longer haven't really time it. can others tell me how fast their boot up are from completely off to all booted up.?
[Nexus 7 Original Development] adstraylight:
It will take longer to boot as it trims the flash storage on every boot. It's like running the Fstrim app every time.
[Nexus 7 Original Development] lucagiampaolo:
Awesome mod! Is there a version that I can use on transformer tf101?

Inviato dal mio Nexus 4 utilizzando Tapatalk
[Nexus 7 Original Development] pjcanales:
OK so from 10-15 minutes reboot time is the norm with this mod. Just want to make sure so I can just charge it while its on.
[Nexus 7 Original Development] Jaloviina:
I've used the mod on MultiROM without any problems! Today I've tried to update my ROM and tried to update the Mod to the newest Version from 23.4. as well.

I've followed my flashing routine and it gave me an updater error 7 and told me that at least 8 MB free space are necessary... Of course there is enough space! After that I've flashed the Version from 21.4. and it works, at least it didn't gave me the error...

So something has changed between this versions...
[Nexus 7 Original Development] CCarson:
It takes me 5-10 mins each boot. 32GB, cache and data formatted to F2FS.

I'd been wondering about that, too--glad it's not just me. I've also wondered whether it makes a difference if SuperSU is configured to allow su during boot or to allow su to system.
[Nexus 7 Original Development] barturblits:
Took a litte bit longer to test. Tried latest version today but still bootloop. Planning to upgrade to purenexus anyway when sigature spoofing is supported so i dont need xposed and will be able to use this mod.
[Nexus 7 Original Development] parrotgeek1:
Yes I need to fix that ugh
[Nexus 7 Original Development] parrotgeek1:
I have never heard of fstrim taking that long before. It is maximum 1 minute for me
[Nexus 7 Original Development] parrotgeek1:
I'll investigate it
[Nexus 7 Original Development] parrotgeek1:
I might have messed up the f2fs mount options
[Nexus 7 Original Development] parrotgeek1:
Hey [MENTION=2583740]adstraylight[/MENTION] [MENTION=5642505]Jaloviina[/MENTION] are boot times still slow when you're on full ext4?
[Nexus 7 Original Development] parrotgeek1:
Someone could have told me this earlier. It's not supposed to be like that (and that doesn't happen to me, but I'm on full ext4). Will switch to f2fs data to test this
[Nexus 7 Original Development] adstraylight:
Noticeably longer, but nowhere near 10 mins.
[Nexus 7 Original Development] dareino:
for my tablet, with little data running on ext4, boot time is 3mins 30 secs....

d
[Nexus 7 Original Development] parrotgeek1:
Can you delete the line in the script that says mount grep remount f2fs ...etc

/system/su.d/01parrotmod.Sh

And see if it's any faster
[Nexus 7 Original Development] adrman:
I'm not using f2fs, but it is rather odd. My wife and I each have a n7, we're running the same rom, Krexus, identical setups, she has fewer apps on hers, yet mine boots normally and hers takes several minutes longer. Once booted there's no difference. I've tried a clean flash and no change. I was thinking of formatting userdata to see if that made any difference.
[Nexus 7 Original Development] parrotgeek1:
Apparently Hynix eMMC chips (in 15% of N7) are faster overall but very slow at forced trim. I'm going to just disable forced trim and let Android handle it overnight.
[Nexus 7 Original Development] adrman:
I wasn't aware of this. Is this something visible when in the bootloader or another mode?
[Nexus 7 Original Development] parrotgeek1:
I forget how to check sorry

But Google seems to be aware of this

https://android.googlesource.com/kernel/tegra/+/android-tegra3-grouper-3.1-jb-mr0^!/

But for some reason in 4.2.2 they reverted it
[Nexus 7 Original Development] suku_patel_22:
Maybe if we can know it's hynix we can disable it while flashing the mod, otherwise we can ignore with during boot if it's hynix.

Would love to have it at every boot for non-hynix emmc
[Nexus 7 Original Development] suku_patel_22:
Just updated my N7 2012 to the latest version of Krexus and Parrot mod. Everything seems to be working great here.
[Nexus 7 Original Development] topoldo:
I have "PureNexus" (GtrCraft) latest (ie April 2016) release with /cache an /data partition formatted with F2FS. Moreover I have journaling off and and about 75 apps (at least this is the number of apps which are optimized when I perform an update) in my Nexus 2012, 32GB. No trimming because I usually switch off my tablet every time I don't need it and no limitation of processes in background. I have about 75 apps installed or, at least, this is the number of apps which are optimezed when I update my system.

In these condition the boot time from the switching on of the Power button to the appearance of the initial screen to swipe to access apps, is about 1' 50".

I'm using ParrotMod_Grouper_Universal_2016-04-23_10.36.39.zip with no particular kernel installed. I'm using that provided by The PureNexus ROM.

Just FYI.

[Nexus 7 Original Development] parrotgeek1:

[Nexus 7 Original Development] nereis:
[MENTION=5723969]parrotgeek1[/MENTION]

Was looking at zram0 partition and noticed it's default at read_ahead_kb 128 / nomerges 0, so I went ahead and disabled read ahead and any attemp to merge.

Assuming ram / zram behaves as really fast storage, with low latency, I think this makes sense.
[Nexus 7 Original Development] parrotgeek1:
very interesting, I will do it in the next version
[Nexus 7 Original Development] parrotgeek1:
update: WTF? i have a hynix apparently and 90 sec boot time but i have like 20gb free

Maybe it's Kingston? or if I filled it up it would be slower at trim?

please run

cat /sys/block/mmcblk0/device/name

And

cat /sys/block/mmcblk0/device/manfid

[everyone else do this too, also tell me whether boot is slow]
[Nexus 7 Original Development] parrotgeek1:

As I said, it is slower but nowhere near the times stated by others. I have the lowly 8G version of the grouper btw.
[Nexus 7 Original Development] suku_patel_22:

[Nexus 7 Original Development] adrman:
I flashed the latest version on both tablets. Mine boots in 1:28 with 5.55/13.36gb used and hers in 4:38 with 5.85/13.43. Once booted, I can't see any difference in performance. I'm just glad to have an explanation for the disparity.
[Nexus 7 Original Development] adstraylight:
So it seems that the Kingston variant is the slow trimmer, and the reason my tablet is relatively fast is that there is literally less to trim...(?)
[Nexus 7 Original Development] :
MAG2GA and 0x000015 for mine.

What does this mean?
[Nexus 7 Original Development] parrotgeek1:
Samsung movinand. How fast is your boot?

Boot time (out of recovery) with today's parrot mod:

1:47min

Fstrim enabled in the mods before, didn't make a huge difference.
[Nexus 7 Original Development] parrotgeek1:
Okay I'm starting to think it's Kingston that's slow. (Makes sense given my experience with a brand new 64gb Kingston flash drive ?). If 10 minute boot guy has Kingston that settles it.

I have also a stupid question but i wanna be sure :).

If i have already installed supersu , do i need to flash supersu againg right before parrotmod every time i update or install parrotmod ? or can i simply flah only the new parrotmod? thanks
[Nexus 7 Original Development] parrotgeek1:
Only parrotmod
[Nexus 7 Original Development] dareino:
your wifes tablet is same as mine , well my is 32g and mine does boot fast but I noticed its takes longer everytime I boot..today it was around 3;45 secs. A few days ago it was 3mins exactly.

*oh so I just read your post on boot times..so I guess mine is considered slow
[Nexus 7 Original Development] parrotgeek1:
Version 2016-05-01 [v2]

Switch the trim heuristic to just "don't trim on Kingston"

Attempt to fix CPU1/2 being always online, and cpus going on/offline randomly (remove sdcard taskset)

Ok but can you investigate the emmc chip behaviour. I dont think the kingston version is the cause of some long boots
[Nexus 7 Original Development] parrotgeek1:
OK I'll try, but why do you think that? Are there some people with other chips that still have long boots? Or what do you mean?
[Nexus 7 Original Development] GtrCraft:
I have a kingston emmc chip myself and trimming and booting are under 2 min
[Nexus 7 Original Development] parrotgeek1:
Does it still have a long boot if you delete your own trim script and delete the test manfid && thing from before fstrim in mine? (i.e. force it to trim)?
[Nexus 7 Original Development] parrotgeek1:
What is that script? Can I see it
[Nexus 7 Original Development] adstraylight:
