how about in stock rom 4.2.2?.

did u include a non oc version? with latest one? also the deepsleep issue
[Galaxy Grand Duos i9082 Android Development] RichyE:
I did a second opinion for you on Glade rom and it boots without a problem, also Aero control works.

I am able to set all the settings and they stick.

I cleaned cache to be safe just in case and it booted in on go and all the settings I changed stick with reboot
[Galaxy Grand Duos i9082 Android Development] bayubm:
i flash on Rom CosmicCM 4.4.4 V5.6 and stuck at Galaxy Grand duos logo :(

so I flash again to EvolutionKernel 1.7.6 by kwl and work again my device.
[Galaxy Grand Duos i9082 Android Development] codekidX:
I assume you downloaded the lollipop version thats why you got stuck on boot logo.

Kitkat version direct link here - LINK

the stock cpu frequency is set on all kernel so if you don't OC it'll become a non-oc kernel ;)

Greeting Everyone !!!

I'm using [MENTION=3117667]pawitp[/MENTION] CM12 ROM. Its battery backup is not as satisfactory as CM11. So i tried to install frost. but owing to OTA updates i tried to restore Cm12 native kernel via the Frost Bar. But it didnt change. I tried many times but it was a faikure.

Is there any safe way to backup & restore Cm12 kernel(pawitp) in case i need to revert back to the native kernel.

---------- Post added at 08:28 PM ---------- Previous post was at 07:48 PM ----------

How to backup the Current kernel before i flash frost kernel so that i can restore it later. I'm sing pawitp's CM12 now
[Galaxy Grand Duos i9082 Android Development] Rommel Espinosa:

I'm looking for a kernel that allows call recording from the line itself, as required by all call recorders I've tried. The default kernel on pawitp's AOSP 5.1.1 doesn't have this feature. Does your kernel have it? If not, will you consider adding it?

Is it me or anybody else facing poor battery backup after flashing the latest update?

I am on RR LOLLIPOP and had the previous version of this kernel flashed. Battery life was awesome, my phone lasted almost a full day in 1charge. Since flashing the latest version of this kernel, I had to charge my phone twice. Battery is draining very fast even on idle mode with no wifi/ 2g/3g enabled. I even callibrated my battery but no improvement was found. My battery is also new, so there is no problem with my battery as well.

Using SmartHassv3 with sio. No other tweaks made in kernel.

[MENTION=4532929]codekidX[/MENTION] please help for maintaining a better battery backup.

- if you have not downloaded the frost kernel yet and wanna install ---> go to system/build.prop and at the end type ro.us.version=2.19 (any version less than 2.25 because it is the latest version)OR if you know exactly what version you are using enter the version and reboot

NOTE: make sure that ro.us.version prop is present or else the app will crash !! fixes are being made

- Donwload the update studio apk from here. Link (top right hand corner)

Great work thanks for your time

Dont forget to update the Title ;)

What is your recommended configuration for optimum performance and battery backup?
[Galaxy Grand Duos i9082 Android Development] codekidX:
I use smartassH3 and SIOPLUS. If you are on latest cm12.1 I would suggest you to use cfq or row I/O scheduler.
[Galaxy Grand Duos i9082 Android Development] neves4:
Hey [MENTION=4532929]codekidX[/MENTION]

I'm using your kernel since may (I think), and would lie to thank you for your awesome work! i'm having great battery life and performance.

One thing that I'm missing: How can I enable BFQ ? I'm only seeing cfq/noop/deadline/row/sio/sioplus but I think the one CM supports is BFQ, right?
[Galaxy Grand Duos i9082 Android Development] codekidX:
Isn't there BFQ in the I/O scheduler list ? If not then I'll fix it today.

Also keep looking at the changelogs page HERE. I will try to port double tap to wake to our device though it'll take some time.
[Galaxy Grand Duos i9082 Android Development] neves4:
BFQ is not listed for me, only cfq, noop, deadline, sioplus and row. I'm using cfq now, but it some times give too much priority for some apps, then everything lag and I need to reboot. Oh, and I'm using cm 12.1.

And the DT2w, is a great feature, would love to have it in grand duos :)

One question, does it drain a lot of battery?

Thanks!

EDIT: [MENTION=4532929]codekidX[/MENTION] , how can I download version 2.33 ? Thanks :)
[Galaxy Grand Duos i9082 Android Development] Paul_Days:
I also am not seeing BFQ +1
[Galaxy Grand Duos i9082 Android Development] codekidX:
2.33 version available for downloads with bfq option choosable !

Also you guys can try experimental kernel release here ! - LINK

If you guys face any problem with experimental release post logcat file here - LINK

What is experimental release?

- It contains all the new and wanted features ported from qualcomm kernels, since our device is based on broadcom and it is highly unlikely to work on our devices. But some features are too hard to port and can take a lot of time but it can be done.

Experimental release will be compiled and uploaded every Monday and the changelogs will be here - LINK

O3 optimizations have had some performance bumps in only certain devices and I don't know how our device will react. I can build it and upload it in experimental release but may or may not have glitches in framework.

Adreno idler is for msm devices and if you see the code its implemented very deep and may brick our device. So I wont touch that part !
