[Galaxy S III General] leonardo-lavazza:
Hi, if you are updating to a new major Android release (i.e. from 4.1 to 4.3) it is strongly recommended to do a full wipe.

In order to keep your data, it is best to run backups.

Some users experienced problem with their EFS when changing firmwares, so an EFS backup is a must.

Check out this thread for details:

> Samsung Galaxy S III I9300, I9305 > Galaxy S III General > [REF] IMEI / EFS - Know this stuff (i9300) - including "no network"

Titanium Backup is an excellent tool to backup your apps and the app data (root is required).

It is also recommended to copy the content of your internal SD-Card on a PC (and also the content of your external SD card, if you have one).

If you install a custom recovery, you can make a backup of your whole system including apps (i.e. CWM, PhilZ, TWRP).

Good to see some kernel love :)

Could you elaborate as to why you don't think cm11 won't work please?
[G Pad 8.3 Original Android Development] aventu:
CM uses different kernel sources usually, but I am not sure if it is still compatible.
[G Pad 8.3 Original Android Development] whoamigriffiths:
I can confirm that this doesn't work on cm :)
[G Pad 8.3 Original Android Development] naruto.ninjakid:
Stock ROM Supported ?

Does this support or do you plan to make one for the stock rom ?
[G Pad 8.3 Original Android Development] aventu:
I could, yes. But there must be enough demand. I personally don't like manufacturer roms, they are often antiquated and overloaded, so it's up to the community.
[G Pad 8.3 Original Android Development] naruto.ninjakid:
I believe many of us are running the stock ROM but you could do a poll or something to be sure. Anyway thanks for your work.
[G Pad 8.3 Original Android Development] zahir32:
Thank You

Thank you for branching out in this direction. I'm keen to try it but am currently on Malladus 4.2.2 because it's the only custom rom that works with XBMC.

Would your kernel on Mahdi change that?
[G Pad 8.3 Original Android Development] dsmitty166:
Thanks man. Glad you like mahdi
[G Pad 8.3 Original Android Development] Canadoc:

For those interested, the app I made for the v510 to enable knock_on will work for your kernel as well, or so I've been told.

You can also enable manually if you wish, but only after full boot. See same thread for details.

Thank you, i didn't wipe anything just flashed it, all went well.
[G Pad 8.3 Original Android Development] Cal:
I was following your posts, and found only the kernel named as below:

dyn.Kernel-r4-CM-0319-ob.zip

Do you have the file name of what you installed? Mine (the above) installed, but did nothing new...

Thanks very much! ☺
[G Pad 8.3 Original Android Development] LiamAtkins90:
Hi friend, I used the dsn kernel on page 17 (a personal build I think) from the OP.

But I'm now in L/S CM11 4.4.4 and see no need to flash the dsn Kernel.

Since Infected_ imported codecs for media and sound we now have a near perfect ROM :D

I have a backup off the kernel incase I feel adventurous.

But I feel no need to flash at this moment.

Maybe if another kernel comes out 4.4.4 compatible, I may Consider.

But for now I'm sticking with Infected_ stock kernel.

:)

Peace Bro

Hey buddy,

Good news I tracked the file down :D

https://www.dropbox.com/s/sqso2h7yl6qt4x5/dyn.Kernel-r4-CM-0319-ob.zip

I actually just recently flashed to this 4.4.4 build because I was getting random hickups in the interface,

Same process as before no wipes just flashed, all went well :D

I will continue to use this kernel on top of CM builds until I physically can't (Tablet won't boot) then I will look into other kernels.

Hope all goes well friend,

Report back if the flash went well, and if the kernel is OK etc.

But I think its the same as you linked to in an earlier post.

Its there anyways for your experimental needs ;)

Happy flashing!
[G Pad 8.3 Original Android Development] Cal:
Thanks!! :) I'll get back if it's different than the one I tried. Also will report how it turns out.

EDIT: It is titled the same as the one I had before...but still your effort is greatly appreciated. I uninstalled that Kernel because I was getting some strange boot flashes that stated something wasn't working, or something like that - at least I didn't understand what it said, and only saw it on a cold startup. So went back to my nandroid backup of Infected's CM latest nightly - with the stock kernel I see nothing happening. JFYI, I shut down instead of sleeping overnight...seems to work best and lets me see booting errors in the morning as I did with this Kernel that you provided. You might want to check a cold boot...it may have only been on my end.

Appreciate your time to find and post - very kind of you!

Cal
[G Pad 8.3 Original Android Development] LiamAtkins90:
Sorry to hear it wasn't working right.

The error is maybe the 'secure boot error' maybe,

I will do a cold boot in a minute and see.

I'm sorry it wasn't working.

EDIT: mine booted fine. From a cold boot up.
[G Pad 8.3 Original Android Development] DSC05:
I tried it also on infected cm11 and all I have to say that this kernel works better than stock kernel, especially regarding micro stutters with noisy beeps.
[G Pad 8.3 Original Android Development] Cal:
It's working well for me too now! We should ask the author of this kernel to keep at it! Below is his name on the kernel, or

Oubeichen

~ he is from China if I recall correctly - but his posts are very frequent in this thread, so a PM might get a response:

Kernel Version

3.4.0

Oubeichen@ubuntu2

Wed Mar 19 16:08:41 CST 2014

It does seem to save battery. Could the Ubuntu2 source be the secret, or is that common??

Also, I believe (and this is from a definitely non-programmer) that until the kernel version number changes - this present kernel (named above) will be OK with even the later versions of CM 11. At least we will know immediately when our tablet doesn't boot! :rolleyes:

Regards!

Cal
[G Pad 8.3 Original Android Development] LiamAtkins90:
Good to hear bud, I tend to play some games on my Tab and on CM11 4.4.2 it was brilliant. Very little heat, great battery and no slow downs. I hope 4.4.4 is just as smooth.

Seems this Build goes hand in hand with this CM ROM :D

I will add though I'm using it on Stable CM weekly releases.

(Can't comment on Nightly CM compatability but someone put it wasn't working ???)

Don't know if that's still the case though.

Yeah he is a Chinese Dev (I think). very talented also.

This Kernel is definitely better than stock.

(No offence to Infected_ he's a very talented programmer. Maybe it the CM source codes causing problems. Either way he's made an awesome ROM none the less)

This Kernel Build has fast charge built in but I haven't tested it. :( EDIT: fast charge doesn't stick, Tryed activating with FauxClock App, but the Dev did say it's not compatible with the FauxClock app. I just turn brightness right down when I charge it, does the job.

Yeah Judging by last CM build and The latest stable booting up with no problems. I'm guessing were OK for now :D

I bet Android L when it's ported to CM will have many many many differences in the source code.

But by then ART will be pretty much optimised and 'lag' should hopefully be a thing of the past. :)
[G Pad 8.3 Original Android Development] Cal:
Agree to all you say.

I'm running it on the latest Infected has up - which I think is the CM nightly 4.4.4 of the 11th of July...so it performs well on v.4.4.4 CM - Also JFI - I've been mixing some of Infected's optimized Roms with the downloads of the regular CM Roms, and they intermix just fine. Of course I always try during the week to use Infecteds' as they may be a bit smoother. But my point is - this kernel will run well on either, the stock or the optimized by Infected or intermixed. (I have yet to try and update by overwrite with this kernel installed - but I'm sure it will be OK, and then install this kernel over the one installed -

but for safety, check the version of the Kernel on the original CM to see if it moved off of 3.4.0

)
[G Pad 8.3 Original Android Development] LiamAtkins90:
Great, thank you for confirming it works great Experimental and stable CM builds.

And that's what I have done, I just saved the kernel on a file on the internal SD, when I upgrade I just boot first to let it set then boot into recovery and flash the Kernel.

I think our next build will be the L build so I don't know if this kernel will still be compatible :'(

But the CM team done a great job getting ART running on ther ROMS so I'm hoping some great L kernels come in by the then, if this Kernel doesn't work.

Android L looks awesome.

All the improvements :D

Not to keen on the light colour theme though :eek:
[G Pad 8.3 Original Android Development] Cal:
I'll try and understand the change-log. :) This does really all I need it to do. I mainly want to see battery usage improvements...& stability improvements. Pretty darn good like this!! :good:
[G Pad 8.3 Original Android Development] bjcrj:
Which kernel are you guys getting good results with?
[G Pad 8.3 Original Android Development] LiamAtkins90:
I've linked to my Dropbox mate further up the thread :)

It's a CM kernel confirmed works on CM stable and nightlys.

If your trying on Mahdi or CMB or any oher CM based ROM,

Backup boot in custom recovery so you can easily get back to your ROM if it doesn't boot.

Great man ;)

Have you come across a weird buzzy noise whilst playing games, watching movies, YouTube videos?

Its on every ROM I've flashed except stock LG which just plain sucks haha!

Playing music through Appolo works flawlessly no buzz at all.

It's weird because I can watch say 20-30 minutes no problem, then bzzzz I loud obnoxious speaker buzz. :eek:

Sometimes it's sooner.

Its my only complaint, must be hardware but again, as soon as I go back on stock its fine.

Havnt tried during Netflix or Putlocker or anything so I'll have to see....

I'm also running it on Mahdi. It has been running very well. It is super smooth. Can't really tell what the battery life is like because I need to go through a few discharge / charge cycles. I had it undervolted to -75 and I would get random reboots just opening an app. I changed it to -50 and I was connected to VPN, downloading, streaming Google Play Music, and downloading tracks (pinning) with no issue. Hope that helps. Thanks to the dev for such an awesome kernel. :good::good::good::victory::

Are you using the stock performance settings in this ROM to adjust the under volting?

I use Trickster Mod.
[G Pad 8.3 Original Android Development] jonup:
First off Thx [MENTION=3970977]reborn90[/MENTION]. Long time waiting for kernel development.

You can undervolt the lower frequencies more than the higher ones. 750mv should be fine at 384mhz
[G Pad 8.3 Original Android Development] aventu:
First of all I want a stable release with all important features, after that I will think about supporting "older roms". ;)

Yes, the higher frequencies have relative low voltages compared to previous models like Snapdragon S4 Pro. But the lower ones have still similar voltages.

It should be, hopefully, the same standby time like stock, but I'm not happy with it. I see a lot of too high cpu time when it should be asleep and the dynamic governor settings are extremely conservative in this state.

Faux or Franco gamma/color settings should be portable.
[G Pad 8.3 Original Android Development] Canadoc:
Great news if you can pet this gamma features.

Well last night first night with this Kernel and Mahdi Rom battery seemed to drain 1%per hour which is not great add the stock LG rom would drain that amount in 8 hours. Will have to see what was keeping it awake. I see the email policies are different as I can set them to a max of 1 hour sync on I map vs. 4 or 8 hours
[G Pad 8.3 Original Android Development] aventu:
The problem is the "surfaceflinger" service, which kicks the cpu load to 100%. The reason should be an insanely fast looping request from something related to earlysuspend or lateresume. This happens sometimes while suspending the device I guess and also while charging.

I already found some lg patches inside the kernel which should prevent this behavior, but it is only partly working I think. I will do my best to fix this KitKat issue.:mad:
[G Pad 8.3 Original Android Development] Canadoc:
I am a bit new to the technical side of things. This surfaceflinger service why would it do that to the cpu but not in LG ROM?

Is there anything I can do in my settings or apps to minimize this waiting for a fix?
[G Pad 8.3 Original Android Development] anomalous3:
Surface flinger has been broken as long as I can remember, lots of patches from mfgrs and it still screws up sleep.
[G Pad 8.3 Original Android Development] bckrupps:
So just to be safe here will this run on the Malladus rom ok?
[G Pad 8.3 Original Android Development] Canadoc:
But what does it do? If it is well known to cause problems and manufactures seem to be able to patch it then why can't it be patched by Google
[G Pad 8.3 Original Android Development] aventu:
The service is now responsible for suspend and resume on rom side as far as I know, so battery consumption is normal and necessary, but not with 100% load for a short time. These are all speculations, I have to debug this.

I can't find the source code. Just backup boot with your recovery, lookup the button combination to boot directly into recovery and try it. And report afterwards please. :)
[G Pad 8.3 Original Android Development] jonup:
The kernel sleeps pretty well if you ask me. Not great, but better than lg.
[G Pad 8.3 Original Android Development] bobo69:

[G Pad 8.3 Original Android Development] Canadoc:
Had your rom installed clean. Flashed the kernel and have been using for past 3 days.

Flashed your rom update today. Rebooted it worked fine but saw in settings it over wrote the kernel. Reflashed the kernel and cleared caches. Would goto the lg screen then screen would go black. And not boot further.

Spent a lot of time seeing up my device. Why would I need to clean install I am coming from same rom
[G Pad 8.3 Original Android Development] dsmitty166:
The kernel must be updated because of the new vendor blobs.

We just switched to them on the last version, hence why it stopped working.
[G Pad 8.3 Original Android Development] Canadoc:
Ok glad it's nothing I did wrong. Hopefully when the kernel gets updated gamma control can be added.
[G Pad 8.3 Original Android Development] :
If you are still having trouble with boot (lg logo appears then it goes black after and no adb or anything) this thread helped me with getting into recovery without adb. I originally couldn't find anywhere that mentioned a way to get into recovery without either ADB or via 'reboot recovery' command in terminal emulator/reboot via extended reboot menu but this method on the link below works!

http://xdaforums.com/showthread.php?t=2606683
[G Pad 8.3 Original Android Development] jonup:
Just fyi. Every time you flash a ROM it installs its own kernel, so you need to flash your kernel again. When you flash a ROM, it automatically wipes cache and dalvik so you don't have to. When you flash a kernel you shouldn't wipe anything either. I don't think that is your issue but there have been cases where wiping cache and dalvik had caused issues when flashing kernels.

This is just FYI that should save you time over time ;) There a lot of people out there that will tell you to do a lot more wipes than it is ever necessary.
[G Pad 8.3 Original Android Development] mikelav456:
