Wow guys! I just did the optimized Qualcomm update for devalk and cache...I think that's what its for. Flashed it in twrp...loving these scores.

I'm on stock ROM.
[Nexus 7 (2013) Original Android Development] konradsa:
What are your settings (CPU/GPU clock, etc.)? And which version of the optimized binaries did you flash (M8, Z2, ...)? My Quadrant score is only about 8700 with Elemental X all default settings and M8 binaries.

All I did was download the 2 zip files in the op of this thread http://xdaforums.com/showthread.php?t=2546120

And flashed in twrp...I saw 1 score that was like 35000....wut? 1.94ghz CPU and 470mhz GPU I think...

I need to leave my tablet out overnight so I can bench it when its cold... Best antutu so far

Didn't think it was possible... Quadrant over 10k!!!

[Nexus 7 (2013) Original Android Development] James_Feltham:
Holy crap! When I flashed I only got 26500 on antutu. What other optimizations are you using? I'll try it again tomorrow when it is cold and see what I get :)

Edit: Also, are you still on 4.4.2 or have you upgraded to 4.4.3? :)
[Nexus 7 (2013) Original Android Development] Philaphlous:
4.4.2. I modded the internals of my nexus 7 with thermal paste on the metal plate over the CPU...Lol guess that's working for me... Stock rom

Slim-flo-4.4.3.build.5.8-WEEKLY-4797 + Elemental 2.13 knocks out wifi (tried 4 times, the kernel was the only variable.)

restoring a backup prior to the elemental install does not restore the wifi. had to do a full re-install.

also no luck on using dalvik/bionic.
[Nexus 7 (2013) Original Android Development] flar2:
I updated wifi using the official Google source. If wifi doesn't work on these ROMs, they have deviated from stock and there's nothing I can do about it.

I test on Stock ROM and Cyanogenmod nightlies and wifi works perfectly on both.

Looking forward to test it on Omnirom :D

Anyway, i don't see any updated link, so i assume you haven't upload it yet

[Nexus 7 (2013) Original Android Development] ikaster17:
Great

hello there everyone, im posting here to help people out with the slimkat wifi issue and the wifi issue... it seems you can flash any kernel you like but it has to be the 4.4.2 version... im right now using elementalx 2.12 the updated version before the 4.4.3 one and its smooth, perfect no issues whatsoever, flash away any kernel but do remember 4.4.2 version... only the updated elementalx 2.12 version is working currently with latest slimkat weekly

Stock 1.5Ghz and Lower 384

CFQ 1792 readahead

-75 Voltage global in trickster

450mhz gpu

gboost disabled and ondemand governor.

Hope it helps :) and Flar2 Great Job Man... :good:

Edit: Flar 2 only one bug to report... when i turn the screen off it takes alot more time to switch back the screen on... like on the last kernel or on any other kernel it would take 2-3 seconds to come back on but 2.12 takes 5-6 seconds to come back on.. would you know why?

i had clean install of slimkat and 2.12 kernel...
[Nexus 7 (2013) Original Android Development] BladeRider:
The link that you mention is not with the updated WiFi drivers.
[Nexus 7 (2013) Original Android Development] James_Feltham:
Oh right hahaha, I won't go that far just to get a higher score on antutu :D

However I would like to inform you that a friend of mine 37500 with his Nexus 5 overclocked to 2.5ghz using these optimizations :eek:
[Nexus 7 (2013) Original Android Development] teddy0209:
What do you mean not updated? It's with 4.4.3 drivers...
[Nexus 7 (2013) Original Android Development] BladeRider:
As the Dev just posted in the previous page, he mention that he has updated the WiFi drives and tested on stock ROM and cynogenmod nightlies so I assume he is going to release a newer kernel. Correct me if I am wrong
[Nexus 7 (2013) Original Android Development] teddy0209:
I guess you misunderstood it mate, he means he updated the kernel to 4.4.3 sources and tested it with stock and cm only, not with other roms... So if it doesn't work on another 4.4.3 rom, just means their still using old drivers. I also tested it on cm and flonaro which is aosp, both kernels work cm/aosp.
[Nexus 7 (2013) Original Android Development] BladeRider:
Oh..my bad. Thanks for elaborating it for me. Guess I need to wait for Omnirom to fix this issue. Cheers

[Nexus 7 (2013) Original Android Development] neo5468:
Hey, if I want to update to 4.4.3, I have to install original, default google kernel first right? But when I installed elementalix, 1 voltage setting was changed (which was recommended by developer of this kernel). Do I have to somehow change everything to default, or does everything change to default automaticly, when I install original kernel, over elementalix.
[Nexus 7 (2013) Original Android Development] flar2:
The google kernel does not allow for changing voltages, so just install it and then reinstall ElementalX

1 more thing. Where can I get stock 4.4.2 KOT49H google kernel ? I downloaded factory image from developers.google.com page, but when I oppend it with 7zip, there is no bootable folder. Is "bootloader-flo-flo-04.02.img" kernel maybe?
[Nexus 7 (2013) Original Android Development] mdamaged:
boot.img is the kernel. In the folder: razor-kot49h-factory-ebb4918e\razor-kot49h\image-razor-kot49h.
[Nexus 7 (2013) Original Android Development] pride_prejudice:
No caf version for 2.12? CM's M7 is still based on 4.4.2, so the latest one we can use is 2.10.1? Correct me if I'm wrong.
[Nexus 7 (2013) Original Android Development] neo5468:
Ok I found it. Do I need any other file, or can I just copy this boot.img to my nexus 7 and launch it using twrp ? Because I read that you need kernel-updater or something as well, or do it via cmd.

I've 4.4.2 Stock rom with ElementalX 10.1 installed. Do i have to install system update(4.4.3) and install latest/compatible ElementalX2.13 or I have to follow any other process?, if yes, please mention.
[Nexus 7 (2013) Original Android Development] mdamaged:
Do a nandroid first.

If you mean taking the OTA:

If you never altered anything in /system (added files to system does not count, just altered), then just flash 4.4.2 kernel (boot.img), take the OTA to 4.4.3, reboot normally, then reboot into recovery and flash ElementalX 2.13.

If you altered /system (if you are not sure, try the OTA, it will fail telling you that a file has unexpected contents), then you can either revert the change or flash system.img from stock 4.4.2 as well as a stock 4.4.2 boot.img, wipe dalvik/cache (make sure you copy out the OTA zip that's in cache before wiping cache though, put it on /sdcard), reboot normally, take the OTA (if you have TWRP follow the instructions below), wipe dalvik/cache, let it reboot with the new 4.4.3 system with stock kernel, then reboot into recovery and flash ElementalX 2.13.

If you have a TWRP as your custom recovery, you will have to flash the OTA manually, just download the OTA, then boot into recovery and you will find the OTA zip in /cache (or /sdcard if you moved it out of there per instructions above), it's best to have the latest TWRP.

Hi,

two questions:

1. Is anybody running ElementalX-N7-2.12 with Rastakat? Is it compatible?

2. I've been reading a lot about wi-fi issues of custom kernels. Is N7-2.12 having these problems as well? Do I need a patch?

Thanks in advance.

[Nexus 7 (2013) Original Android Development] teddy0209:
If rastakat still uses 4.4.2 drivers, use 2.12, if it has been updated to 4.4.3 use 2.13...

No need for patches, one of the two versions should work...

I am using CleanROM, it works fine with another kernel. Not sure if it is ROM related. Dont wanna do a clean flash right now if that would be the fix.

Tap-a-talked from my Nexus 5
[Nexus 7 (2013) Original Android Development] wantabe:
Quick answer would be yes it can but... Every device is not going to respond the same to different kernels or to the same configuration settings. If you're having problems with this kernel on certain games I would personally try a modest overclock on your cpu and gpu. I'm using 1728 MHz on the cpu and 450 MHz on the gpu forever now, the battery is pretty darn good and heat has never been an issue! If that doesn't clear up any gaming performance issues you have, if any, then I would disable gboost and use the ondemand governor. I myself have to use the ondemand governor instead of the elementalx governor because of a couple games I play and battery life is great.
