I use motley kernel since I have my N7 and im very satisfied... Slightly overclocked CPU to 1.4 GHz and normal gpu speed Antutu reaches over 12000 points...

Battery lifetime is equal to this one... Less updates, but why change something that simply works ;)
[Nexus 7 Original Development] chasmodo:
And we need to know this why exactly...?

Here is my last kmsg sod r20 4.1.2

From my simple experiments its from the wifi advanced settings, if I have it auto off it'll sod, if I leave it on it will always wake up.
[Nexus 7 Original Development] airmaxx23:
You may not find it useful but someone who's currently running Motley's kernel might.
[Nexus 7 Original Development] ÜBER™:
AND? This is not the motley kernels thread. :rolleyes:
[Nexus 7 Original Development] airmaxx23:
And... someone who is running Motley's kernel may read it and switch.
[Nexus 7 Original Development] osm0sis:
Someone should go back to motley's thread. This is franco's thread.
[Nexus 7 Original Development] sladflob:
OK, I know I'm going to be told that I get what I deserve but...

I've side-loaded Flash player to my N7 because I occasionally watch restreamed video and the broadcasters uses Flash to stream the content. I use Firefox to browse to the site as it supports the Flash plugin. This works fine on the stock kernel but on Franco r20 the images look like an analogue tv signal that's all static and coloured lines. I'm wondering if this is a result of the GPU overclocking? Is there an easy way for me to test this?
[Nexus 7 Original Development] osm0sis:
Go back a few pages and find franco's commands for changing the GPU clocks. Using them you should be able to change the clocks back to stock and test if that's the issue.
[Nexus 7 Original Development] ÜBER™:
Clear data on browser and reboot. Of it persists do what osmosis said. Or use the stock android browser... it supports the flash plugin.
[Nexus 7 Original Development] alextso321:
I use franco apps to install this kernel and I also find the franco's commands for changing the GPU clocks, but I am not sure how to use those commands. How do I use those commands? Thanks!
[Nexus 7 Original Development] osm0sis:
Good idea. Maybe clear data/cache on Flash as well.

How do you get stock Android Browser for the N7? AFAIK it only comes with Chrome, which doesn't support Flash.

You can enter them in the Android Terminal Emulator app available from the Play Store. You'll need to type "su" first to get superuser/root access from SuperSU, then use the commands to switch clockspeed on the fly.

Installed it like a normal apk? Came with slim bean.

Very cool. Thanks! I'd never seen it. It came with Slim Gapps? I'll extract it from there and definitely check it out.. :D
[Nexus 7 Original Development] ÜBER™:
Don't think it was the gapps should be included in the ROM zip.

[Nexus 7 Original Development] osm0sis:
Yeah, figured it out. Found the guide here. Hunting down the latest version of AOSP Browser now. Thanks again! :good:

Edit: Hmm even Pure Vanilla AOSP Jelly Bean seems to have Chrome instead of Browser in it now.. :(
[Nexus 7 Original Development] sladflob:
Thanks for the suggestions. I tried clearing data on Firefox and still get the pixel soup.

When I try setting the GPU frequency to 416Mhz by catting to gpu_oc the device reboots. Tried several times now. This should be ok to do from an adb shell, right?
[Nexus 7 Original Development] prestige777:
Latest AOSP Browser
[Nexus 7 Original Development] ÜBER™:
Got that pixel soup too... :(.
[Nexus 7 Original Development] sladflob:
OK, using a terminal on the device I get the GPU frequency to "stick" without the device rebooting. What's the difference between doing this on the device and using "adb shell" btw? It's certainly a lot easier to cut and paste into an adb shell on my PC.

Anyway, GPU frequency change didn't fix the Flash problem. Interestingly, it's the not the videos themselves that don't play, just the navigation screen is completely messed up to the point of being unusable. If I randomly tap and eventually hit a video it plays fine.

Oh, I've upgraded to 4.1.2 too, btw.
[Nexus 7 Original Development] franciscofranco:
Some patience please, I'll release a new version with the new 4.1.2 changes and some fixes soon.
[Nexus 7 Original Development] prestige777:
I had that with Cookies and Cream 1.2.1, I went back to 1.2.0 and it cleared up.
[Nexus 7 Original Development] osm0sis:
Fantastic! I'll thank you once I get some more (8 max :(). Can you give me the link to somewhere reliable I can continually get the new versions as they come out? Then I'll stop pushing us off-topic (my apologies, Franco). :p

Edit: NM, Extracting it from EOS nightlies seems like a safe bet - AOSP based and includes Browser. http://goo.im/devs/teameos/roms/eos3/nightlies/grouper/ :D

Larger Browser.apk file than yours though..?
[Nexus 7 Original Development] M3drvr:
With 700 capable gpu? And is 700 the max possible? Curious what the fsb is capable of handling on these Nexus 7s. Can it handle all these Overclock with CPU included and actually truly increase performance? Or are we just burning battery unnecessary and getting a placebo effect?
[Nexus 7 Original Development] franciscofranco:
r21 is up. Merged all 4.1.2 changes, 4.1.2 ramdisk and reverted to stock GPU speeds now that everyone can clock into the desired clocks.

700Mhz GPU is capable since r20 but I doubt most of our devices can handle that much since all busses increase as well.
[Nexus 7 Original Development] 850T5m:
So still this run on the 4.1.2 boot loader?

Thanks Franco!

Auto flashed r21 and it's working pretty well so far, no SODs like other kernels :)
[Nexus 7 Original Development] irminsul:
Somehow i screwed up my N7, couldn´t boot up franco´s kernel and couldn´t boot up TWRP, or another custom recovery. Backed up, did a full wipe of everything, installed Bugless Beast 4.1.2 and flashed R21. Everything is fine again. Will check how the kernel behaves and if there will be any SOD´s, for my sensitive N7.
[Nexus 7 Original Development] :
I just got a New C9OK device and got my first SOD ever, on r21 and stock 4.1.2.

I also have wifi set to auto-off when idle. I'll test if it's related.
[Nexus 7 Original Development] Ronaldo Forenucci:
RasBeanJelly 4.1.1 09/26 build, r21, Interactive, stock voltage, WiFi always on: Plugged in all night, no SOD.

Question: Does flashing a new kernel with the app, wipe out all but the last back up? I back up every kernel iteration, but when I flash a new one, there is only the last one I did, in the list.

RF
[Nexus 7 Original Development] Lozzo:
The thing I've found about auto wifi off, in my case at least, is that it does not seem to work in my case, and again when I have noticed SODs, I've been able to cure them by "hard" switching wifi off, or disabling location services. I've not looked to see if wifi is waking up when I have location services enabled, but it sure does a lot otherwise.

I tried this for a while, just to see how this appeared on battery stats.

Pic.

Here you can see a shedload of wifi actvity happening when the devices is supposedly "off whilst asleep" up to the point where I awakened the device and turned wifi off manually.

Thanks for the great kernel, I've been using r20 for a few days now and have not had a single SOD, it's very fast and smooth. I just updated to r21, hopefully I keep getting the same amazing results.
[Nexus 7 Original Development] SquireSCA:
Oh yeah, duh. LOL

What permissions? I moved it there, went to Recovery and fixed permissions, but when I rebooted and tried to launch it, it FC's without an error.
[Nexus 7 Original Development] airmaxx23:
Once you move the file to system/app long press on it and change the permissions to:

Then reboot.
[Nexus 7 Original Development] SquireSCA:
Tried all that, cannot get it to work. No worries, apparently there is something jacked with Flash anyway, so I guess I am not missing much. hehe
[Nexus 7 Original Development] franciscofranco:
Yeah something is up with the Wi-Fi. I'll take a lookzor :D
[Nexus 7 Original Development] airmaxx23:
It's there a way to check the GPU clock speed other than looking in the file that changes it?

Its not like you can't make a nandroid back of just your boot if you wanted. Or the entire ROM to revert back.....

Sorry guys but this is exactly the type of stuff that leads Franco to posting it as a fastboot image in the first place. People just don't know what they doing
[Nexus 7 Original Development] leelaa:
I am on about when a new kernel is released and i am not by a computer. I know the reason why he is doing this as i explained it to someone on here yesterday.

Hes released as a boot.img as its his first release for nexus 7, he wants experianced users to test first. And then he releases a flashable zip.
[Nexus 7 Original Development] albundy2010:
Yes Lee. I am aware of that and was not talking about that aspect of it. Was about. the revert back to previous kernel etc. As you stated bottom line is no flashing it without a computer but everything else you can do.

I didn't want to quote anybody nor do I want to make any more posts about the matter and fill the thread up with junk like how to's and general flashing/restoring q&a crap.

What exactly is "data integrity"? Could normal usage lead to data eventually being corrupted, or is this only a concern when you shutoff the tablet incorrectly?
[Nexus 7 Original Development] simms22:
its more of a concern when your device crashes
[Nexus 7 Original Development] Caliyork:
In case anyone was curious about battery life. You could definitely get 10+ hours with medium. What I posted was what I'd consider very heavy use. Screen on for more than 85% of the time, gaming, browsing, and streaming video.

Edit: Basically a stock rom with tablet ui patch and a few minor tweaks.
[Nexus 7 Original Development] AzzaD:

[Nexus 7 Original Development] franciscofranco:
If your device crashes for any reason (lack of battery, sudden crash due to software/hardware failure etc) if you have fsync disabled it has much higher chance of corrupting your system files. Doesn't mean it will corrupt, but the chance of happening is largely inflated.
[Nexus 7 Original Development] nitrox1:
So if your trying a new Rom, which could have potential of crashing (like a nightly), or "if" you introduce undervolting, and I choose to test a lower voltage, which causes a crash, there is then a much higher chance of me losing data and corrupting system files?
[Nexus 7 Original Development] simms22:
if fsync is off, yes.

LIFE SAVER. I got it on the green android and START at the top. Should I press start now?

Thank you a million.
[Nexus 7 Original Development] airmaxx23:
Did you make a backup before you flashed the kernel? You can press the volume up or down buttons to scroll until you see "recovery" then boot into recovery to restore your backup or flash a different kernel. If you just press "start" now you'll probably be boot looping again.
[Nexus 7 Original Development] airmaxx23:
You need to manually change the first four values in the follow file to your desired GPU speed:

sys/devices/system/cpu/cpu0/cpufreq/gpu_oc.

This is a true 750Mhz GPU benchmark.
[Nexus 7 Original Development] simms22:
:victory:
[Nexus 7 Original Development] franciscofranco:
Just pushed r22 with some GPU OC interface changes. So now instead of outputing the entire frequency table you just choose what max frequency you want your GPU to reach, for example: echo 600 > /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc

I've tested it from stock value up to 750Mhz with no problems.

Also bumped the first 6 voltage entries for the CPU an extra 25mV to increase stability.

Have fun overclocking the GPU, but beware, I take no responsibility if you do something stupid and cause a thermonuclear war.

Also added the GPU commands to the second post for the users that eat too much cheese and forget these things :)
[Nexus 7 Original Development] 850T5m:
Sorry, I dont know if this is a stupid question...but I'll ask anyways :)
