r30 seems to drain more battery than stock kernel! :rolleyes:
[Nexus 7 Original Development] tyraelasd:
Ill give it a try, it worked like magic on my gnex.

I dont know how to use adb and the apps its still not compatible to flash 4.2 kernel, what am I suppose to do?
[Nexus 7 Original Development] papeles:
Just bought an N7, came here to do some reading.

Found Franco stuff and reembered the beast he was when developing for my Huawei X5. Insta downloaded your kernel and gonna give it a try.

Cheers dude, keep up the good work
[Nexus 7 Original Development] osm0sis:
Same method for the test builds from the GN side should work. :) :good:

Build images are located here: minooch.com/franciscofranco/Nexus7/4.2/

[Nexus 7 Original Development] osm0sis:
In r30 the bug of it not using frequencies below 400MHz seems fixed. :victory: :)

I reset the app to defaults to test things out for you like you requested. Ondemand is feeling sluggish swiping between homescreens. On the other hand, your new defaults for interactive seem pretty good! Definitely more responsive and smooth compared to ondemand. :good: Thanks franco!
[Nexus 7 Original Development] Jack Barrett:
Working here. Anyway no big increase in scores and performance.
[Nexus 7 Original Development] freakshow999:
From 3601 up to 4702 on Quadrant Standard!

And this is the only 4.2 kernel I've run thus far that does not break Stickmount's usability which caused lock and reboot problems.

I'll let you know if I run into any issues. So far so good so :D

Thanks for the commands, I have started to remember most of it thanks to Franco putting out images. One of these days i need to setup my sdk and adb prompts correctly. Right now i have to download the image then move to the C:\, then open a command prompt from the sdk platform tools where fastboot exist and flash like that. Anyone have an easier setup?
[Nexus 7 Original Development] freakshow999:
If you use Wug's tool in hit the advanced tab and you can flash from there really easily. That's what I use as I've yet to get my regular ABD/Fastboot to work correctly on this device.

Like I said the app needs to be updated in order to be able to download the new kernel. Im in S.Francisco today so that will wait until I get back home.
[Nexus 7 Original Development] nuwan32:
That's impossible to do due to the IPS screen the nexus 7 uses
[Nexus 7 Original Development] opz187:
Does anyone know if init.d scripts are executed on francos kernel? I seem to remember they didnt use to be, correct me if I'm wrong
[Nexus 7 Original Development] sadde:
Is it only me or does the battery drain way faster on 4.2 Franco kernel than on 4.1.2?

Thanks Franco for your kernel.
[Nexus 7 Original Development] eugenechiuu:
4.2 itself has higher battery drain in comparison..
[Nexus 7 Original Development] Jack Barrett:
I also noticed that compared to stock kernel.
[Nexus 7 Original Development] aLPaSLaN07:
Checking atm. Thanks for the new kernel. Was waiting for it..

Edit: It appears to me that the voltages is a little bit high.. for 1.3ghz normally 1000mv is enough but with this kernel it is 1125mv. I'll try to reduce the voltages to see if any stabilization issues occur..
[Nexus 7 Original Development] lordlad:
hi, just checking..does franco kernel works with the Nexus 7 3G version?
[Nexus 7 Original Development] lordlad:
why do you think so.? Other than the inclusion of a baseband radio? What's so different hardware/software wise between the 2?
[Nexus 7 Original Development] phydo:
I agree with lord lad. I would flash it. The galaxy nexus uses the same kernel for CDMA and GSM versions which leads me to believe that it's not in the kernel. If anything the lack of support wouldn't allow the radio to be used. Just make sure you back up your stock kernel first or you would get stuck.
[Nexus 7 Original Development] huyster:
Just temp boot the kernel and test it out yourself?
[Nexus 7 Original Development] Paddington:
Note the link to the downloader automatically lashes r25. r25 does not seem to be compatible with 4.2 ROMs. I soft-bricked and am having to wipe everything.
[Nexus 7 Original Development] osm0sis:
This has been said over and over. You should have checked before flashing. r30 is the first compatible with JB 4.2. That said it shouldn't have "soft bricked" requiring a wipe, it should just be stuck in a bootloop/hang at logo or animation and all you should need to do to fix it is fastboot flash back to the stock JB 4.2 kernel.
[Nexus 7 Original Development] opz187:
Sorry to say, but you deserve it. Why can't you restore a backup or flash a different kernel.. Why wipe anything?
[Nexus 7 Original Development] Paddington:
I'm fixing it the only way I know how to fix it. I deleted a lot of stuff when I moved to 4.2 because I have an 8GB tablet and I had about 3GB tied up in backups and app restores. I deleted all of it, and I was going to make a new backup once I had things running like I wanted. I haven't had a device bootloop/softbrick/hardbrick on me in a year, so I let my guard down a little bit. I am about to attempt to flash the stock image through fastboot in hopes of salvaging everything, but if I do end up wiping everything, it is no big deal. There is little system data on a tablet that I can't restore, whereas with my phone it has things like call log, texts, alarms, etc. that I might want to hang onto.
[Nexus 7 Original Development] opz187:
You can get into recovery right?
[Nexus 7 Original Development] phydo:
Screw recovery. You can get into the boot loader. Download a compatible kernel and fastboot flash boot bzimage
[Nexus 7 Original Development] drose6102:
Anyone using tablet talk? I connect no issues to my 4 but after an hour or longer not using or opening the app, android kills tablet talk and I have to reconnect. Can anyone else verify?

I did not have this issue running stock 4.1.2 with r23 build. I run stock 4.2 with r30 now
[Nexus 7 Original Development] !crazy:
You could try changing min free memory values with ROM Toolbox or System tuner and see if that helps. It probably will.
[Nexus 7 Original Development] drose6102:
I will check out system tuner when I get off work. Not familiar with changing those settings around but I will do some homework. Thanks
[Nexus 7 Original Development] franciscofranco:
I forgot to add init.d routine call on the init.rc, will do later after work :)

Besides the radio theres no changes between the Nexus 7 devices. I suggest you just try to boot the boot.img with fastboot boot boot.img, if it doesn't boot you can just turn the device off/on and it will be back to stock kernel. Let us know how that goes!
[Nexus 7 Original Development] leelaa:
That's very nice info i was unaware you could just boot the kernel temporary
[Nexus 7 Original Development] franciscofranco:
Yep, its VERY useful when testing dangerous stuff. fastboot boot boot.img is the command :)
[Nexus 7 Original Development] chinopski:
same situation happened to me yesterday. Soft bricked,no backup, no saved compatible kernels on sdcard. I used wugs nexus tool kit to push a compatible kernel from my PC.:)
[Nexus 7 Original Development] ZachPatterson:
Kernels <r30 are for 4.2

ONLY

Kernels >r25 are for 4.1

ONLY

I made the mistake of flashing the r30 to my Nexus 7 running a 4.1.2 ROM, got stuck on boot screen...instead of wiping everything out next time do this:

Step 1) Hold volume down + power button until it reboots into bootloader mode

Step 2) Connect USB cable from PC -> Nexus 7

Step 3) Download/install/android SDK tools, specifically the "Android SDK Platform Tools" (Quick tutorial is here

Step 4) Start -> run -> cmd (Run as Administrator)

Step 5) fastboot flash boot C:\Downloads\Path\To\Your\Correct\Kernel\boot-r25.img

Step 6) fastboot reboot

Unbricked ^_^

It's handy having the adb/fastboot commands to fix problems like that...

Ontopic: Running r30 on Grouper and Talapia (3G Nexus 7)

Looks good so far.

Thanks franco!
[Nexus 7 Original Development] formicae:
Um, kernels ≥r30 are 4.2 only. And ≤r25 are 4.1 only. You got it backwards and didn't include the equal-tos.
[Nexus 7 Original Development] osm0sis:
Likely the next build. r31 or something. Definitely looking forward to it though! I missed having init.d support with stock ROM on my N7. :D
[Nexus 7 Original Development] freakshow999:
Make sure you are running the very latest versions of Tablet Talk on both devices. The older cracked app that's floating around will not work. Both versions 1.6 and 1.6.1 had connectivity problems. I am running the newest version 1.6.2 on my Atrix 2 with my N7 running Franco's r30 and Scott's CleanRom 2.5 without issues now. I had the issues you described before on the earlier versions.

[Nexus 7 Original Development] poondog:
HEEEEEEEEEEY, someone I recognize from the Incredible S forums! Haven't seen you around in AGES!

Anyway,

Yes. Gnex is a type of AMOLED and N7 is LCD

That is why the Gnex kernels have the ability to alter the colours, the Nexus 7 doesn't. Because ts a totally different display technology.

Haha yes. Sold that (stupid SMS issues) and got an iPhone (bad idea). Now I'm back and loving android again!

Why can't I set fsync through the terminal emulator? It says /system/bin/sh: can't create *fsync_enabled-stuff*: No such file or directory.

I copy-pasted what is written in the second post but no luck. Same goes for the GPU frequency check and settings.

Even with my file manger I can't find neither of both.

I'm definitely doing something wrong here, just can't figure out what. Any help please?
[Nexus 7 Original Development] drose6102:
Ok I uninstalled tablet talk on the 7 and 4 and reinstalled newest version 1.6.2 so far I have not had a disconnect. If it makes it through the night while I am sleeping then I will know it fixed thanks
[Nexus 7 Original Development] myepicyear:
I don't mean to sound stupid, but first thing I'll ask is did you grant terminal emulator superuser permissions?

If so, then I'd guess (without talking a look at it) that Franco has either a)used a different implementation of fsync; or b) hasn't included it yet for 4.2 kernels.

There is also the possibility that you could have entered the command incorrectly too. Have you ever done things like fsync toggling or color control through the command line interface? If not, you might have gotten a portion of the command wrong when copying it. If possible, post the command you entered, (verbatim) and I, or someone else here would be happy to tell you if you're making a mistake or not. When I get a little more time, I'd also be happy to personally try it out for you and see what's up, provided Franco hasn't gotten back to you by then.
[Nexus 7 Original Development] opz187:
My download speed is blazing fast on this kernel. And flash seems to be fixed..
[Nexus 7 Original Development] aLPaSLaN07:
Fsync and GPU overclock interfaces just work fine.. All you have to do is to give superuser permissions to terminal emulator.. To do that simple type "su" and hit enter.. Then grant access from superuser or supersu.. You're good to go now..
[Nexus 7 Original Development] timbck2:
Yes, the Nexus 7 has an IPS LCD screen while the GNex has an AMOLED. Very different technology. In my opinion, after getting so used to the rich, bright colors on the GNex, the N7's screen looks a little "washed out".
[Nexus 7 Original Development] neo-X:
You are right. I looked at my N7 and thought "colours aren't as deep". Anyway I don't wanna deviate from kernel talk.
[Nexus 7 Original Development] osm0sis:
IPS washes out but otherwise the color reproduction is better than AMOLED. Check the GN color threads. They're a nightmare because there were so many defects and variability of tint. So in summary, nothing's perfect. ;)

Happy to report you don't need to revert to stock kernel to flash the JOP40D OTA. :)
[Nexus 7 Original Development] sahshah:
Cheers Franco the flash issues which used to be present till r25 seems to be gone :)
[Nexus 7 Original Development] indbeegee:
FYI: Also works with Stock 4.2.1 deodexed
[Nexus 7 Original Development] nuwan32:
IPS also eats less battery
[Nexus 7 Original Development] osm0sis:
Not from what I understand.. But I could be mistaken. IPS has LED backlights which use more battery, even when displaying black, than an OLED, since the OLED displays create their own light and are off for blacks, using no power.

Edit: Check out this series of smartphone hardware articles from Neowin. I linked to the display article but they're all actually excellent reading:

http://www.neowin.net/news/guide-to-smartphone-hardware-47-displays
[Nexus 7 Original Development] nuwan32:
http://mobileraptor.blogspot.ca/2012/04/ips-versus-oled-power-consumption-and.html?m=1

Basically on an ips it takes the same amount of power per pixel for any type of color, whereas for AMOLED, the intensity of the light depends on the power used, so black takes the least, white the most. That's why I use fully inverted apps, and the difference was noticeable. Normally on my nexus it would be impossible to hit 3.5 or 4 hours but with fully inverted gapps and inverted versions of my most used apps I get 3 hours minimum in daily use.

Edit: that's screen on time I was talking about there :p

Yo osmosis are you using ondemand or still using interactive. Ondemand aint too bad for me over here

Googling is literally the only way I can think of to find out. That's how I'd do it.

Still interactive over here. ondemand was okay but interactive still felt smoother and more responsive overall.
[Nexus 7 Original Development] billsky83:
it's shame we don't have a flashable zip for this kernel
[Nexus 7 Original Development] osm0sis:
Yeah.. boo hoo. :rolleyes:

It's easy peasy to move the downloaded .img file to kernel_backups and use f.Ku's kernel backup/restore functionality. It's easier than CWM even. And very soon the JB 4.2 kernels will be on the updater itself.
[Nexus 7 Original Development] opz187:
Yea interactive is definitely still a more fluid experience. But I'm getting crazy good battery life ondemand. I'd imagine the life on interactive must be pretty good as well. I'm getting a little more use out of the lower frequencys (100-300mhz) than i was on r25. Not as much as I'd like but its worth it, this is the best kernel for 4.2 imo
[Nexus 7 Original Development] timbck2:
Why? It's just as easy to type the command "fastboot flash boot boot.img" then reboot as it is to boot into recovery and flash a. zip file. I don't understand why so many people are making such a fuss about the lack of a flashable zip.
[Nexus 7 Original Development] osm0sis:
I blame the hip hop. :p

..and the toolkits. Definitely too many people out there way too reliant on toolkits and CWM. They dumb down the population as a whole.

This is from efrant's sig. Pretty much explains the attitudes of both sides. Very worth the read (like all the links in his sig). efrant has a good rant about toolkits somewhere too. ;)

[Nexus 7 Original Development] timbck2:
You, sir, are correct!
[Nexus 7 Original Development] phydo:
Except I have to fire up my Mac. But since I added the ssd it takes like .5 seconds. Honestly I just throw the IMG in the kernel-backups sdcard folder and restore it from the app. If I fubar'd it then I'd fast boot in a second. Honestly how do these people ever get a recovery on their nexus to do anything with a zip without fast boot? Because don't they have to fastboot flash recovery to even install like supersu?

Be super lazy and add the android SDK directory to your path so you can fastboot from any directory!
[Nexus 7 Original Development] ricardowec:
Yes, there is quite a difference. To fastboot you need a computer with framework installed.

Recovery is done. In the tablet.

More so, I just screwed my tablet by downloading v25 which is what the downloader suggests.

I came here for a solution and got myself into a problem. My bad.
