[Nexus 7 Original Development] i root SGH i777:
kernel

i am new to rooting my nexus 7. just rooted it this morning. am i able to use this kernel or other 4.2.2 kernels if my nexus 7 is rooted with stock rom.
[Nexus 7 Original Development] dark2099:
This kernel works fine with 4.2.2, using it with the latest paranoidandroid myself.
[Nexus 7 Original Development] dark2099:
Don't want to be too much of a pest, but anything fun happening on the Nexus 7 front from you [MENTION=4195844]show-p1984[/MENTION], either kernel or KControl related? Not saying the kernel does need work, but I always love flashing new work!
[Nexus 7 Original Development] show-p1984:
The beta kernel is still undergoing testing and will become stable soon. KControl is in the last 33% of development and the Nexus 7, as all T3, is (except the thermal tab) fully supported.
[Nexus 7 Original Development] dark2099:
Thanks, been using the latest beta since you released it about a month ago. Zero issues, been that way with any of the "betas" you've done, can't tell the difference between them or a stable release.
[Nexus 7 Original Development] ShockBuddy:
Awesome Kernel Name xDDDDD

Testing, seems to be pretty good ^^
[Nexus 7 Original Development] kbeezie:
Can fuse.exFat support be added to the kernel? Or is that not really a Kernel issue? Reason I ask is because normally I would use StickMount (which can use exFat binaries off the /sdcard to mount exFat drives via USB-OTG), but now that SlimBean as of 6.2-Weekly includes USB-OTG support for auto-mounting, I don't need to use stickmount anymore... except it doesn't support exFat, which I assume is a kernel issue.

[MENTION=4195844]show-p1984[/MENTION] Hey mate, love bricked, I learned much from your work, specially on N4.

Now i got a N7, no sweep2wake support on grouper? It's one of the best things you invented mate, I just love it :good:
[Nexus 7 Original Development] dark2099:
I know it's something he mentioned, but think the driver rewrite is a little more work than expected.
[Nexus 7 Original Development] dark2099:
[MENTION=4195844]show-p1984[/MENTION] I was using Zarboz's kernel for a bit on my HTC One, noticed he had included your badass governor, was curious if it was compatible with the Nexus 7 and if we would see it? Thanks!
[Nexus 7 Original Development] JayanWarden:
This is running great so far, but one thing I noticed is that the min- frequency automatically locks to .91 ghz after a while without me or any apps interacting with the kernel settings.

left everything to standard in the aroma installer, and even resetting the min frequency with trickstermod does not help.
[Nexus 7 Original Development] show-p1984:
I could make it compatible, but I don't see any point. It was quite nice on older devices, but on the newer ones ondemand does a good job.

(on Tegra3 devices my modified ondemand does a better job :p)

It's a feature, not a bug.

Scroll down to the second mpdecision section (replace msm with tegra wherever necessary)

bluetooth tether?

I'm running stock jb with the latest version of bricked kernel. Ever since switching over to this kernel I'm unable to Bluetooth tether to my phones 3g connection. Does anyone know how to fix this besides flashing a different kernel?
[Nexus 7 Original Development] Tipkaros:
There's a new stable release dated 2013-06-24 over here http://bricked.de/index.php?action=kdownload&device=grouper&release=stable&type=aosp but no one is saying anything about it?
[Nexus 7 Original Development] show-p1984:
It's just the beta made stable. :)

So if you are on the beta you will be fine.

I never tried to use bluetooth to tether anything else than gps, I may try it though for the sake of bug fixing if I find a free bluetooth tether app that is working on jb in the market.
[Nexus 7 Original Development] norcal61:
I've never had to use an app in the past. I just pair my phone with my nexus 7 and in the nexus's native Bluetooth settings there is an option to use the phones 3g data connection for internet. I've used this feature since July of last year. Since using this kernel it doesn't work. Everything seems to be connected on both ends but no internet.
[Nexus 7 Original Development] dark2099:
Just to be sure I'm understanding you correctly, the new stable has no change from the beta, you just moved that build to stable status?
[Nexus 7 Original Development] norcal61:
I really love the performance with this kernel but I had to switch back to Franco's kernel because I can't tether my phone to my nexus 7 with this kernel. Can you please add support for this so I can switch back?

[Nexus 7 Original Development] poondog:
Hey Dennis I remember your N7 wouldn't boot or something a month or so ago, is everything okay now?
[Nexus 7 Original Development] Remoteconcern:
Latest kernel is great. I wasn't on the beta before. It really adds back performance on the nexus 7, which did not age well.

Thanks showp, will surely buy kernel app when released to show support :)
[Nexus 7 Original Development] tibere86:
I'm running the 5/13 experimental kernel with Franco's interactive settings and I am getting great battery life. I also get less wakelocks with Bricked kernel :good:
[Nexus 7 Original Development] bsw11:
Can someone please verify if the latest stable or beta will work with Smoothrom 5.1 or not?

Thanks!
[Nexus 7 Original Development] dark2099:
I've never seen show mention that it will not work with the different variations of roms.
[Nexus 7 Original Development] bsw11:
Well so far it looks like you would be WRONG about this. I flashed Bricked and now my device is BRICKED!

When it tries to boot is shows a screen that looks like an old black and white TV that is out of sync.

WHen I try to go into recovery it sits on the Google name screen and does nothing.

Any clue how to recover from this mess?

Update - On my 2nd try to recovery it started TWRP and I was able to put franco back in and reboot. Too bad, I really wanted to try Bricked as it was the past on my past devices.

What is the preferred ROM for this Kernel?
[Nexus 7 Original Development] dark2099:
Which GPU option did you use, IIRC there are some issues with either/both the 484 and 520 MHz options.
[Nexus 7 Original Development] bsw11:
I might have used the 484 - I will give it one more go and avoid that - right after I finish my Nandroid BU -) and let you know. Thanks.

How do I access IIRC?

---------- Post added at 10:24 AM ---------- Previous post was at 10:11 AM ----------

That was it, booted right up without GPU overclocking - which is a bummer because I was hoping to OC the GPU because that is where I am trying to fix some Dice player playback issues using HW om some MP4 I have that don't play perfect. Oh Well.

Does anyone know if the "HW" codecs are just using the GPU or actual pre-programmed silicon? In other words can Kernel code change the behaviour of the HW codecs or not?
[Nexus 7 Original Development] thecdn:
I always overclock the GPU to 520 with no issues. Use mostly slim rom with some rasbean and others.
[Nexus 7 Original Development] dark2099:
Must just be the 484 setting then. All I know is it's time to get a new 7, charging port on mine is dead from a fall out took while charging, luckily can get the 32gb locally for $200+tax.
[Nexus 7 Original Development] Prey521:
Latest version doesn't seem to want to boot my N7. It just keeps looping the Google screen at initial boot. I've tried diff combos of the GPU OC and nothing.
[Nexus 7 Original Development] dark2099:
So you have tried the stock 416mhz gpu option?
[Nexus 7 Original Development] nadiros:
Tested this as well and can't boot any GPU OC version... Just to verify.

416 works though.
[Nexus 7 Original Development] dark2099:
Figured I would through this out there for anyone to try as well, but a couple days ago, I did a full system wipe with CWM, not just the factory reset option, but the system partition to, which forces you to sideload/push a rom, and after a reinstall of everything, with the latest stable kernel, things seem to be much better. Even though I only used this kernel, the clocks/cores behave much better, haven't done much testing of battery life since I don't use the tablet intensively, but I wouldn't be surprised if that was a touch better too. So if you don't mind completely setting up your tablet again, might be worth it to do, help clean out any possible conflicts from older versions or other kernels you've used.
[Nexus 7 Original Development] lagoskon:
Can you try the following settings / options in aroma installer to verify if GPU overclock works.

CPU max 1600

CPU min 204

Screen off max MHz 620

GPU overclock 520

Governor OnDemand

Scheduler Deadline

What is your result??? Nexus 7 booting with GPU overclocked or not ??

[MENTION=4195844]show-p1984[/MENTION] Will we be seeing a bricked kernel for the 4.3 operating system? Thanks!

Here's a large stick, want to face palm me with it? :eek:
[Nexus 7 Original Development] sgt. meow:
I'm sorry. Excitement over the 4.3 release turned me into a fact Nazi.
[Nexus 7 Original Development] dark2099:
I've been messing around with PC's and electronics long enough to know better than what I did. Just think I was so excited myself, I couldn't think straight. My comment was meant to be more funny and playful than not.
[Nexus 7 Original Development] sgt. meow:
I know. We are only human, and we will make mistakes. So it's all good. Anyways have you seen the kernel changes for 4.3 anywhere around?
[Nexus 7 Original Development] dark2099:
Nope, checked the forums on my phone at work earlier to see if the 4.3 system had come out so I could try it. Figure that might be a bit longer, hopefully not too much though.

Waiting for all root issues to be resolved first. Just want to try out the newer kernel.

Haven't tested it myself but Roger Keegan reported it to be working.

I said OT, it was a bug in my app not your kernel.

Just provoked another SOD by leaving the N7 alone for a few minutes. Sorry I cannot attach the last_kmsg as I don't have my wincrap with me, but basically is a loop on suspend trying to set freq to 475000. Nothing else.

This Kernel runs quite stable for me all the day on the last CM10 nightly (100-1300 MHz, ondemand)

You can try turning up the minimum clock speed to 102MHz rather than 51MHz, it's worked for me so far today.

No problems on CM10 nightly from 10/4 after ~18 hours. I simply flashed it from CWM, did not change any settings at all.
[Nexus 7 Original Development] sert00:
instead for me no problem of SOD "yet"..honestly i rarely have them also on others kernels,also some that usually people claims to have SOD frequently.for now all good,i'm on C&C,and with this kernel fits my need completely,fast and snappy,no prob of lag with the UI,fast app installing\loading and i can say seems ggod the battery..but too early yet for this measure.hope to continue without problems,happy to not see a SOD.The only thing i miss from others kernel is the gpu OC,i'd prefer for daily usage at least 520 mhz,but also 600 is good!

Not booting for me either
[Nexus 7 Original Development] show-p1984:
I just flashed it on my now charged up Nexus 7 (had the black-static low-battery screen all day yesterday) and I can confirm that it is not booting. How Roger could have said that it is I don't know. Probably an honest mistake.

The reason for this failure is that the init ramdisk gets scrambled when loaded into the memory. Probably some changed load addresses in the new boot.img that lets the kernel and ramdisk overlap. Will have to look into that :)

I pulled the new kernel, for those having any issues after flashing: Just flash over the stock boot.img from stock rom or from your custom rom. Here is the grouper 4.3 stock boot.img from Google's factory images:

[Nexus 7 Original Development] sgt. meow:
[MENTION=4195844]show-p1984[/MENTION]

Try the ramdisk from M-KERNEL with a normally compiled zImage. Should work. I had the same issue and M-KERNEL's ramdisk fixed it. Or you could try mine (ro.secure=0, ro.adb.secure=0 etc.).

Cheers.
[Nexus 7 Original Development] show-p1984:
Well that would be the brute force method of fixing it. I am rather shooting for elegance as I don't want to replace everyone's ramdisk with a fixed one (that's also why I won't provide full boot.imgs).

It's probably only the load addresses that are wrong for the new boot.img. I haven't had yet time to compare them, but I will have later this day.

Which ROM? I am on CM nightly from 17th Aug and its running nicely :) I flashed at ~90% this morning so I can't comment on battery yet.. but I remember back on 4.1.2 Bricked was one of my fav kernels for its balance between battery and performance
[Nexus 7 Original Development] show-p1984:
For some ppl the middle gpuoc step (484) isn't working, I have no clue why because nobody sent a log up until now and my device runs it like a charm.

I have not altered the charging drivers. It is normal that the device doesn't charge blazing fast if you use it and if it's close to fully charged.

You just can't float charge Li-ion batteries without them getting mad. So I don't. Iirc I patched in fast-charging (disabled by default) a while back for some ppl, but that is not exposed to aroma and not encouraged to use. It's just there because people asked about it.

Good. Two features to go, the rest should be fool proof on nearly any device (even on unsupported ones, which will have limited functionality). Planning on releasing it very soon now.
