Thanks to osm0sis who kindly sent me the correct ramdisk changes for this release. Hope you enjoy this.
[Nexus 7 Original Development] slebit:
Awesome! Will try it right away!
[Nexus 7 Original Development] ffejy462:
Works great! However, Fku download failed every time. Auto flash worked though.

[Nexus 7 Original Development] JovieBrett:
There is something wrong with the color gradient after flashing r77 kernel. Capturing as a screenshot doesn't show the actual glitch.
[Nexus 7 Original Development] franciscofranco:
No.
[Nexus 7 Original Development] slebit:
That is most likely your rom. I don't have this problem with my tablet.
[Nexus 7 Original Development] JovieBrett:
But this was just happened after flashing FK r77 kernel on my Grouper with CM11.
[Nexus 7 Original Development] slebit:
So if you flash your previous kernel it's gone?
[Nexus 7 Original Development] JovieBrett:
Yeah. There's no problem on the color gradient/graphics on the latest build of CM11 on grouper but after flashing the latest kernel, that show'd up. The same color gradient issue with first alpha build of PA 4.0 if you've seen it.
[Nexus 7 Original Development] franciscofranco:
I don't know what is that, I haven't changed anything in the video subsystem of the Kernel.
[Nexus 7 Original Development] JovieBrett:
Oh.. okay. Thanks Francisco!
[Nexus 7 Original Development] sjknight413:
Hmm,

After that guy pointed it out I'm definitely feeling that the gradient banding got a lot worse after flashing r77 too, big thick bands going on here.
[Nexus 7 Original Development] JovieBrett:
Yeah as I mentioned...
[Nexus 7 Original Development] slebit:
Are you using cyanogenmod? Or a rom based on it?
[Nexus 7 Original Development] sjknight413:
Yeah, latest cm11 nightly.
[Nexus 7 Original Development] slebit:
Maybe it's something with cm. I don't have problem with my screen with mahdi rom.
[Nexus 7 Original Development] Edwin184:
Thanks a lot, works smooth and stable, indeed no more root problems.
[Nexus 7 Original Development] osm0sis:
No color issues on stock either.

TWRP is broken as **** right now on grouper. Use CWM.
[Nexus 7 Original Development] ffejy462:
2.6.3.1 has been broken for a while. 2.6.3.0 works fine....
[Nexus 7 Original Development] jyesucevitz:
Trust that I am a Franco fan, but had the gradient issue as well. I tried M-kernel and xperience kernel after and the problem stopped. Just saying.

[Nexus 7 Original Development] fozzie:
That doesn't work here with TWRP 2.6.3.1.

For one, there are no reboot options under Advanced; they are all under the top level option of 'Reboot'. If I reboot back to recovery then the problem remains.

Would you mind posting a link to where you saw the workaround. Thanks.

[Nexus 7 Original Development] ganeshp:
with stock + r77 im seeing lots of stuttering/frame drops on home screen and also wile multitasking (changing apps/ going to recent apps menu and selecting a app then the app animation stutters a lot ) ..I havent seen this on r76

if anyone else on stock rom with this kernel didnt see the above ..please tell me ..Assuming its user error I'll probably do a fresh installation of the stock rom again
[Nexus 7 Original Development] andrew9292:
Working great so far, Purity 23/12... no gradient issue here
[Nexus 7 Original Development] madanlmg:
use google play.

I too have twrp 2.6.3.1 and had the same problem.

Then I installed the franco kernel installer from Google play, and then managed to install the kernel via autoflash method.

Try it out. Its way simpler. :cowboy:

The link is given by Franco on his OP.
[Nexus 7 Original Development] tcat007:
Or use Flashify and the boot.IMG, also very easy and fast.
[Nexus 7 Original Development] fozzie:
Thanks, but I don't have a problem installing the kernel. As you will have seen from my previous posts, I've already said that it can be installed using either f.Ku or by downloading the boot.img and flashing with fastboot or with something like Flashify.

What we're talking about here is specifically the problems with getprop assertion failure when using TWRP release 2.6.3.1, that isn't a problem with the previous release, 2.6.3.0. The post I quoted was suggesting a workaround, which doesn't actually make sense based on the menu options suggested and also doesn't seem to work anyway. I was asking the poster for a link to where they found the workaround.
[Nexus 7 Original Development] Gspin96:
That gradient thing... I didn't test this kernel, but the background gradient has always had some banding problems since it appeared in android 4.0 due to a not-so-good dithering on it.

If that's the problem, it's plenty of solutions on the web, ow which two are quite easy.

One is a CM theme chooser theme i made which doesn't theme anything but the background (http://xdaforums.com/showpost.php?p=38799003&postcount=108).

The other solution is an xposed module which does the same thing (http://repo.xposed.info/module/com.oranav.ditheredholobackground).
[Nexus 7 Original Development] :
Anyone else experiencing a slight delay when turning the screen on with r77? Don't know if it was like this with previous kernels, but compared to the stock kernel, theres definitely a noticable delay.
[Nexus 7 Original Development] s33d1ing:
I had a slight delay with r76 as well as r77.
[Nexus 7 Original Development] andrew9292:
Not sure if it's a delay or expected... Something like 500ms, less than a sec tho.

---------- Post added at 01:17 AM ---------- Previous post was at 12:46 AM ----------

Can minimum lowered backlight/brighrtness be merged from the N5's kernel? saw the changelog it was in it...

Value '9' in other n7 kernels seem to really darken the screen like it turned off the backlight or something, appropriate for lights-out midnight usage and it saves tons of batt :D
[Nexus 7 Original Development] aLNG:
I can confirm that..stock + r77, rollbacked to r76 and the lags disappeared
[Nexus 7 Original Development] fozzie:
No lags here.
[Nexus 7 Original Development] robgee789:
I'm really liking this kernel with purity Rom very smooth just gotta see how the battery lasts
[Nexus 7 Original Development] adefxda:
Working well with cm11 zeljko latest build..

Amazing fast..

[Nexus 7 Original Development] steviemch:
On stock rom and no problems you mentioned whatsoever.

Also don't have the colour banding problem others have mentioned. Had problems with lag on r76, but on this latest kernel my N7 is lag free and smooth.
[Nexus 7 Original Development] RootTheMachine:
Oh my god... My tablet has been running like absolute poop for the past few months, no matter what kernel was present. But with r77, it's actual usable again, and super smooth!

Folks having lag issues, try clearing FKU app data and restarting.

Problem with r77

After using r77 for a full day, I experienced something weird. I heard a weird sound from the speaker when I unlocked the screen, and noticed that everything was extremely slow. The only solution was to just hold the power button to turn it off and on.

Bad news everyone.. I gave up the Nexus 7 in "the divorce" from my (now) ex-girlfriend this week, so I won't be able to troubleshoot, test or fix over here anymore. :(

I've got a Nexus 7 32gb flo shipping out next week though so I'll be heading over there. Best of luck all! It's been a fun ride with the odd little Nexus adopted/orphan child that is grouper. :)

Ahhh! My B&N Nook app quit working when I installed this kernel. I'm not sure if the issue was present in R17 or not because I didn't open the app on r17. But on stock kernel it worked fine. I've tried to clear data, clear cache, uninstall/reinstall, reboot doesn't matter, i just can't get it to work anymore. It starts to index books then FC. Help? Thanks.

I'm missing the lowmemorykiller interface in the Nexus 7 kernel and the Galaxy Nexus Kernel.

I'm using the v6 supercharger script, and switching minfree values according to my needs (more multitasking or less).

Is the plan to bring the interface back?

---------- Post added at 01:30 PM ---------- Previous post was at 01:14 PM ----------

Just looked into the git repository and find out:

oom_adj is depricated (which is the missing interface) and oom_score_adj should be used instead.

A quick scan through the code seems that if "CONFIG_ANDROID_LOW_MEMORY_KILLER_AUTODETECT_OOM_ADJ_VALUES" is defined the "old" interface would still be active and the values would be converted.

---------- Post added at 01:40 PM ---------- Previous post was at 01:30 PM ----------

As I mentioned :) Quickscan. Seems just a format of the input.

And i made a mistake. adj is missing not oom_adj under /sys/module/lowmemorykiller/parameters/

Strange that there are so many SOD reports. My n7 likes to SOD, had them several times a day on trinity and _thalamus kernel, but not a single time on François.

R18 feels extremely smooth by the way. Did you include the bfs v5, Francisco?
[Nexus 7 Original Development] sert00:
what's thalamus kernel?
[Nexus 7 Original Development] franciscofranco:
I suggest you contact Google, thats off my control.

I included BFQv5 on r17 yes.
[Nexus 7 Original Development] mjforte:
This is pretty crazy...just flashed r18 and with 30 minutes of screen time I'm still at 100%. I've never seen anything like this.
[Nexus 7 Original Development] ÜBER™:
What are you doing? That has a big play in things.
[Nexus 7 Original Development] franciscofranco:
Ok lets play a little more: r19:

* Added interface to set companion core max frequency - this can be useful if you don't want the device to ramp up pass X frequency with the screen off

To change the frequency just do this: echo X > /sys/devices/system/cpu/cpu0/cpufreq/cpu_lp_max (X = frequency you want, for example 400 for 400Mhz, 200 for 200Mhz).

* Merged few fixes to the GPU overclock interface to make it stabler and better scalable with new frequencies

Let me know how that works
[Nexus 7 Original Development] osm0sis:
Very nice! Will the companion max freq also be added to the updater in the future? :)
[Nexus 7 Original Development] franciscofranco:
Yes GPU oc and companion core max clock too. Maybe tomorrow if I'm in the mood :)
[Nexus 7 Original Development] ÜBER™:
Bro's nexus shut it self off last night after flashing r18 after he OC'd the GPU. Dont think its done it since at least that i know of. I will OC my GPU to see if it happens the same as well as test this new Max Screen off deal. :D thanks.
[Nexus 7 Original Development] Metallice:
Looks great. But shouldn't you also be adjusting the G min frequency to one less than the LP max freq as well? Otherwise I could imagine some things getting screwy.
[Nexus 7 Original Development] franciscofranco:
I experienced it once after I released r77. I'll put my Sherlock Holmes hat and investigate :)

Well, you cannot really compare the N5 and N7 panels/drivers etc. I can *look* and see if there's anything related to display brightness and if so I'll tweak the brightness values.

I cannot see how is that Kernel related since you're the only one having that issue. I bet the Aliens did it.
[Nexus 7 Original Development] :
I'm not saying it's directly kernel related, but it does seem possible since it doesn't happen with the stock kernel. I posted a very similar bug I experienced with r76 on KRT16S here, but no one replied, so I guess I might be the only experiencing the issue. I'd post more info from logs and whatnot, but I'm not very technically proficient with this stuff. Everything is pure stock. Heck, even the settings are all default. The only thing I changed is the wi-fi sleep policy to "only when plugged in".

Thanks for replying nonetheless and thanks for continuing making superb kernels :good: They work flawlessly, atleast on my Nexus 7 2013 and Nexus 4 :)
[Nexus 7 Original Development] Zorigo:
Sorry, but just to quickly clear some confusion, does this work on 4.3? (I know it says 4.4 on the OP but I can't find the 4.3 F kernel page)
[Nexus 7 Original Development] Kotaless:

[Nexus 7 Original Development] blinde:
With R77 my N7 takes about 4-5 seconds to show lockscreen when power button is pressed. Which is pretty damn annoying since I can't be always sure whether it's just in sleep or off completely. What setting should I change?
[Nexus 7 Original Development] andrew9292:
What setup you have?

Im on purity rom and occasinally there is a half second or one second delay at most...

I noticed r77 screen-off cap freq is 120Mhz, if there was background processing of some sorts it might delay starting the screen maybe? Try a higher freq cap?
[Nexus 7 Original Development] blinde:
I'm also on purity rom and default settings in FKU. I guess I have to check things and try some other settings.
[Nexus 7 Original Development] carpon:
what about the battery using this kernel ?! STO ?!

i'm thinking to try this + purity rom
[Nexus 7 Original Development] Short Viking:

TWRP 2.6.3.1 is broken.

Do one of the following:

- Downgrade TWRP from 2.6.3.1 to 2.6.3.0

- Use CWM

- Download & auto-flash with f.Ku

- Download the .img file and flash with Flashify
[Nexus 7 Original Development] numus:
That is strange because M-Kernel flashed fine.
[Nexus 7 Original Development] fozzie:
Not really; it probably doesn't have the assert check. Take a look in the zip at the update script. (If it does, then paste the commands here please.)
[Nexus 7 Original Development] numus:
Yup it doesn't... I have to find which system has fastboot to flash the downgraded TWRP.
[Nexus 7 Original Development] fozzie:
You can use Flashify for that too ;)
[Nexus 7 Original Development] tcat007:
yes. I use Flashify and boot.img on my N7; I use TWRP and zip on my N5 (not sure why I don't use Flashify for it, just habit.
[Nexus 7 Original Development] Souron29:
Open the updater script and delete the assert command. Then it'll work in any recovery
[Nexus 7 Original Development] sgt. meow:
The assert bit's there for a reason. It's for some careless (and maybe even mindless) users who may flash, say a 2013 kernel on the 2012 version. The better way is to just downgrade the recovery or switch to CWM.
[Nexus 7 Original Development] Souron29:
:D people do that too!!!?
[Nexus 7 Original Development] sgt. meow:
I haven't seen any such cases here, but judging by the number of 2013 people that post here by mistake, it won't be long. I know of a few people who permanently bricked their X8s by flashing a X10 kernel.
[Nexus 7 Original Development] andrew9292:
Never thought 8 hours was possible on a 1 year old battery plus i wasnt even trying. but on r77...wow

Tq franco and devs for the great work!

[Nexus 7 Original Development] berkos:
Impresive, did you change anything from stock settings. I had quite bad battery life, 4 hours of youtube tops. Even with less walkock time compared to m-kernel
[Nexus 7 Original Development] frigidazzi:
I have this problem too. Only after letting the tablet sit over night (not charging) then when in pick it up the next day.

Also when this happens the battery has drained a lot (like 90 to 25 percentage). Android os and system both show top of the list in this case.
[Nexus 7 Original Development] :
Yup, that sounds like the exact same thing I'm experiencing. Wrote a more detailed explanation here for r76, but the issue still occurs with r77.
[Nexus 7 Original Development] andrew9292:
Only disabled fsync & smartdimmer on the kernel side. All others are franco's original settings & brightness about 15% throughout. Usage was web browsing mostly (dolphin), chatting (line), youtube app, facebook app, gmail app, no gaming. Purity rom.

Rom side heavily optimized though, disabled nfc, sync, no widgets etc. Deleted tons of pre-built apps like phasebeam, movie app, smspush, user dictionary, hangout...nearly 20 apks iirc. Almost everything i wont use is gone for good or disabled if cannot be deleted.

Not sure that has a direct impact on battery life tho, just gives me peace of mind knowing those stuff wont be running at all or cached in ram. Careful tho if u wanna try, deleteting some mandatory stuff can pretty much ruin the OS.

So, not sure why but r77 from 76 gives much more screen for me, only change was the kernel. Gonna keep this. Cheers! :highfive:

Oh yea, force gpu render is enabled as it helps reduce scroll lag on apps like adobe reader. Dunno how it affects batt tho
[Nexus 7 Original Development] Software Guru:
I has this kernel on my Nexus 4, think its time I tried on my Nexus 7
[Nexus 7 Original Development] :
Good choice! I was very disappointed how slow and laggy the N7 got after some months. I finally flashed this kernel and was literally blown away how smooth everything was all of the sudden.

Thanks franco!

Long delay after power button wakeup

On r77 and noticed that waking up the device from sleep using the power button takes too long, say a few seconds, used to be faster previously using stock kernel or r76...

Yes this problem has already been addressed. Franco will fix it wen he finds tym

Hi there, I can't do uv with fku. Is it possible do uv with a script?
[Nexus 7 Original Development] slebit:
This kernel doesn't support uv.
[Nexus 7 Original Development] yukkio:
Hmmm I think I flashed a Franco kernel with uv. But, I will try to check how handle the battery
[Nexus 7 Original Development] Gspin96:
Once, franco kernel had an UV interface, but voltages were not really set. Now, since android 4.3, he decided to start over and re-add features one-by-one, which is good since this way they can be integrated more carefully (i don't really know if "carefully" is the right word, english is not my main language).
[Nexus 7 Original Development] Souron29:
Reduce boost freq and hispeed freq for better battery but be careful ;)
[Nexus 7 Original Development] bobmarsh72:
Hi Franco,

I raised the issue regarding using a ps3 remote as a native android controller in your N5 forum. I have noticed on N7 the same happens with 2 cores sticking at 1ghz.

I thought i would let you know that i tried m kernel and the above issue did not happen with the cores going to the lowest frequency.

Unsure if this information is of any use but thought i may a well let you know.
