My grouper has been happily back on KitKat for almost a year, on an old Validus test build with parrotmod, and running fantastic. Thanks :) [MENTION=5723969]parrotgeek1[/MENTION]

Arter flashing this mod on autodroid my bluetooth stopped working. My device is a tilapia with autodroid 4. 4
[Nexus 7 Original Development] parrotgeek1:
i dont know why that happened but to fix it replace /system/lib/hw/bluetooth.default.so with the one from autodroid rom
[Nexus 7 Original Development] abhifx:
a new validus with parrotgeek's setting would be nice

Hi [MENTION=5723969]parrotgeek1[/MENTION]

I know you have long since moved on from this but wondering if you could help me?

I installed Parrotmod 2.0 last night using your instructions in the OP (had a stock 5.1.1 device) and all went well initially

Out of curiosity I ran the terminal command to check that it was running and I got a "not found" message.

I thought then that perhaps by flashing the mod first and then SuperSU that it didn't work so I booted into recovery again and flashed the mod.

However my device now will not boot. The Google logo comes up but nothing after that (not even boot animation), just a black screen with backlight on

I tried reflashing the mod and SuperSU as per the instructions again and a few other other variations but the problem persists. It is still there even after a factory wipe in TWRP.

Do you know perhaps what the issue might be? I did notice that after rebooting system from within TWRP, after the Google logo, the screen flashes and you can see the last screen from TWRP for a split second. Then back to black

Any help appreciated
[Nexus 7 Original Development] parrotgeek1:
Please reinstall stock 5.1.1 with fastboot and then follow the instructions in the right order. I will admit I have no clue *why* it doesn't work when you do it in the other order, though.

The screen glitch thing after the Google logo is normal and you will notice it on stock ROM sometimes.
[Nexus 7 Original Development] Deanicus:
Thanks for the reply!

Unfortunately it seems that the USB port on my device is broken. It charges but my computer won't recognise it anymore (tried other machines and cables but still the same)

I also tried using an OTG cable with a flash drive but that was not recognised either

I've ordered a new port which will arrive on Monday. Hopefully once it's replaced I'll be able to bring it back to life

Thanks again for the help!

I need some help.

I installed this mod on 4.4.4 stock ROM, and I have only one problem with it. My bluetooth isn't working anymore, I tried the fix that OP suggested in an earlier post, to replace bluetooth.default.so file with the one from autodroid rom but it didn't work. I also extracted the file from the system.img, but it didn't work either. This mod works perfectly with other 4.4.4 based roms, only on stock I encountered this problem, and I don't want to switch to other roms because stock+parrot is the best combination I could find for my nexus, I tried many combinations and this one is the best speed wise that's why i don"t want to change So if OP or anyone else can help me with this i'll be greatful.
[Nexus 7 Original Development] parrotgeek1:
replace it with the one from stock because you're running stock

I told the other person to replace it with the one from autodroid because he was running autodroid

Anyone managed to fix parrotmod read-ahead being 2048 with newest su ?
[Nexus 7 Original Development] Galaxyninja66:
This made CM12.1 on my Nexus 7 much slower, I don't know how, but normal CM12.1 with pico gapps runs atleast 2x faster without parrot mod. It only seems to speed up <5.0 versions of android.
[Nexus 7 Original Development] Crim Soukyuu:
For me, it got slower too. But once I manually set read_ahead_kb to 0, it sped up again. For some reason, read_ahead_kb is not applied correctly, the other values, including parrotmod.running property is set correctly though.
[Nexus 7 Original Development] parrotgeek1:
That is odd. I'll try to look at it. Keep in mind I don't have this tablet anymore though.
[Nexus 7 Original Development] codlike:
I flashed Parrotmod onto Omni rom (android 4.4.4), after flashing Parrot, the bluetooth was crashing.

I tried copying the original Omni /system/lib/hw/bluetooth.default.so back after flashing parrotmod but the bluetooth its still crashing. I just wondered if there was anything else I could do.
[Nexus 7 Original Development] parrotgeek1:
not sure, sorry
[Nexus 7 Original Development] codlike:
thanks for replying, its nice you still keep helping out.

did you ever do a version without the bluetooth upgrade in as all the speedups seemed to work.

and is there anyone out there who could take the apk apart and take the bluetooth libs out?
[Nexus 7 Original Development] parrotgeek1:
edit the zip with 7zip and delete the folder bt40 then flash it
[Nexus 7 Original Development] codlike:
Thankyou, again. That was surprisingly easy.

Does this script work with [ROM][NZH54D][2017/12/05][Grouper|Tilapia][F2FS/EXT4]Android 7.x AOSP without modification?
[Nexus 7 Original Development] ltjmax:
Read rom description
[Nexus 7 Original Development] cobalt100b:
I know that the initial post says it doesn't work with Nougat. But within this giant thread, I've also read several posts which indicate that it does indeed work with Nougat. Somebody asked the question about nAOSP 7.1.x and another user confirmed that it does work with that ROM.

But then again in another post I read, that a script has to be modified for the Mod to work with Nougat.

Therefor again my question to anybody who can answer it, whether it does work with AOSP 7.1.2 and if so with or without modification?
[Nexus 7 Original Development] mausbock:
Please read the ROM description from AndDiSa (changelog) more carefully. The ParrotMod performance tweaks have already been applied to the ROM by AndDiSa since version 20161028.

There is no need to apply the mod twice. [emoji6]
[Nexus 7 Original Development] lollazzo:
I have no answer by terminal, what I have to do?

[Nexus 7 Original Development] Klyno:
Hey ! I don't know if anyone is still reading this but when I try to flash the .zip file via twrp, an error occurs. It seems that my device is not a Nexus 7 2012. Note that I've tried to install both versions.

Any solutions are welcomed.

Cheers !

PS. Here is a picture of the error.
[Nexus 7 Original Development] TheNec:
First make sure which device you have and if it's supported and then check if you meet the requirements. After that update your recovery, choose the correct version and try it again.
[Nexus 7 Original Development] lotte67890:
You may also want to try the latest TWRP version...
[Nexus 7 Original Development] parrotgeek1:
Try the old version mentioned in the first post
[Nexus 7 Original Development] parrotgeek1:
update twrp to at least 2.8
[Nexus 7 Original Development] Adiker:
Does this mod work with Magisk ? I think it is not because my device was slower than with SuperSU installed but I'm not 100 % sure :P
[Nexus 7 Original Development] parrotgeek1:
It does not.
[Nexus 7 Original Development] parrotgeek1:
I just fixed the bluetooth crash in 4.4. (Download dates are the same because it is the only fix)

To do it yourself, replace /system/lib/libbluetooth_jni.so with the one from your current ROM

Hi I am trying to do this on my nexus and got stuck on step 5.

[Nexus 7 Original Development] parrotgeek1:
It doesn't. Use an Android 6.x ROM.
[Nexus 7 Original Development] TNSMANI:
While it is true that this Fix doesn't run with the ROM you linked, in my experience that ROM is very smooth and reasonably lag free even without this.

This is not to take anything away from this Fix which I was using earlier and which really helped.
[Nexus 7 Original Development] TMCThomas:
Hello everyone, I can't even get passed step 1 currently :p. I've rooted with kingroot before on my galaxy s3 mini which works fine. However when I try it on my nexus 7 (2012) 32GB, it gets stuck at 90% for about 30 seconds and then just reboots the device. Has anyone had this issue aswell?

EDIT: nvm, i'm an idiot, downloaded kingoroot instead of kingroot.
[Nexus 7 Original Development] tombunyon:
Is there any possible way to port this to Magisk? I'm not really a fan of SuperSU as it's closed source and triggers SafetyNet (mainly the latter bothers me, I could live with the former).
[Nexus 7 Original Development] broomer68:
I don't know if it works on the good old Nexus7 2012, but FDE should preform most functions (and more) of the parrot mod.

[Nexus 7 Original Development] federico72:
Wait. I'm not sure if I have understood. Is the processor overclocked or not on beta? BEcause on KA the maximum is still 1.3ghz.
[Nexus 7 Original Development] parrotgeek1:
this mod is compatible with all custom kernels unlike original version which uses its own kernel so you can flash one
[Nexus 7 Original Development] federico72:
Sadly, AFAIK there is not a overclocked kernel for 6.0.1 (for now).
[Nexus 7 Original Development] parrotgeek1:
That's unfortunate. I don't know how to compile one and my computer is really low on space (128gb ssd). Try pming a developer
[Nexus 7 Original Development] federico72:
Tested with the other n7 I have . Installed and rebooted as supposed to do.

Unfortunately didn't resolve the issues of bt headset sound shuttering because... It can't! Seems I'm not the only one with this issue and not only with a nexus 7 2012 playing real racing 3.

To confirm this I've installed asphalt 8, another high demanding game and the audio is just fine.

The script did endeed something. On my 6.0.1 rom aosp based the system seems a bit more responsive and the multitasking is better. Please consider I'm on f2fs for data and cache, trimmed every day.

Thanks for great patch!

But have some questions.

Installed original mod on N7 factory 5.1.1, all steps as in instruction, success, first boot in 5 mins, GREAT speed increase. Impressive.

Installed on same N7 factory 5.1.1 - have troubles. Kingroot cannt give root with spontaneous reboots and message "root cannt be activated, try desctop version". Activated only in 10-15 attempts, ok.

After rooting, installed flashify, twrp, mod, supersu. But first boot was not completed in 5-10min, it takes more than 1 HOUR and device was rebooted manually. After that, device started quickly, but no any speed changes and no root - superSU tells 'binary file SU need to be updated'. Tried to flash MOD and superSU again, no any effect.

What can I do now? Mod installed, new desktop and new options aka overclocking, but no speed burst :)

Will try to fix SU, do fstrim manually and flash a new version from 07/02
[Nexus 7 Original Development] parrotgeek1:
What do you mean?

You installed it once and it was faster, then you installed it another time and it wasn't?
[Nexus 7 Original Development] kayotster:
No, I have 2 Nexus 7 2012 devices.

Mod was successfully installed on first device, and failed on second one. Can be initial FS trim a very long on old device with almost fulled flash?
[Nexus 7 Original Development] parrotgeek1:
yes. Also try to delete some apps from /system before installing, it might run out of space

Beta still working fine with cm12.1 finally can use my N7 for daily use even playing games, the only thing I don't understand is why haveged process is not running but speed increase is there no need to use trimm apk anymore.

I flash the universal mod on my grouper with dirty unicorns rom(system ext4, data&cache f2fs). The system seems to be more responsive than before and I'm sure that it's not a placebo effect. Without this mod my tablet have some lag when automatic rotation is on (especially on YouTube app). I'm impressed! Thank you so much for your work!
[Nexus 7 Original Development] animatrix999:
Used this on PhoenixOS on my Nexus7 an the speed difference is very noticeable an no issues so far =)
[Nexus 7 Original Development] kayotster:
Wasted some hours, and done this..

1) kingroot was not deleted completely, and conflicts with supersu. After install/remove and flash superSU device become normally rooted. But with warnings.

2) UPDATE-SuperSU-v2.46.zip from first post instruction - is bugged ****!! On some devices it gives 'su binaries need to be updated', but update in any way is not possible. Because a version bug in this package..

U can check this, file armv7/su includes strings "2.45", not "2.46" as needed.. I don't know how it work on other devices - it must not work correctly.

Flashed ZIP many times, erases 'old' files, tried 'fixing' scripts form internet - no effect. 2.45 SU binary, 2.46 APP and version conflict.

Installed 2.49 beta - and voila, everything became good.

I recommend to change 2.46 to 2.49beta in installation manual, link to this version - https://download.chainfire.eu/740/SuperSU

Hi,

[Nexus 7 Original Development] parrotgeek1:
weird. I included a patch that enables bluetooth 4.0, but I forgot that CM includes it already. I didn't think it would conflict though. try to replace /system/lib/hw/bluetooth.default.so from CM, or reflash rom and remove it from parrotmod zip

I will add check for rom which already can support BLE and not install the lib
