[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] CZ Eddie:
That was a little harsh. :D

Video's are IMO, a good idea. If you don't know what you're doing, then follow instructions. So, the OP did good IMO.

That video is only a couple weeks old and is for the Galaxy S4.

I didn't watch it (no sound card) but it doesn't matter now.

OP, what does happen when you press the volume up + power + home button to get into the recovery?

Did you try pulling the battery for 30+ seconds yet?

You should not be seeing a white AT&T screen at any time. You should be booting into recovery, where you will then flash a new ROM.

Well, I mean it shouldn't have killed your current ROM. But that could be a separate issue.

If you can get into recovery, then just toss a ROM onto your external SD card if you have one.

If not, then use ADB push to push a ROM onto your internal SD where you can then flash it.

Or, Odin back to stock.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] zelendel:
To be honest videos are a bad way to learn to flash a device. This thread is great example as to why. Had he not rushed and learned what he was doing first we would not be here

Telling people to read in this forum is futile. It only gets you called names like do*che and d*ck. Kenny knows, he had to clean up a response to my post telling someone they needed to do some reading. It's sickening how lazy people are these days. But it's the truth. You won't learn anything by being spoon fed the info. Sometimes the best answer to give someone is to just read. This isn't a support center. It's a development forum. People need to learn the basics on their own. Zelendel said it best in his legendary post. And if I could find it right now I would link to it.

And if you're gonna follow a video, try one that was made by someone like AdamOutler, not some rando with a random website.

[LG Optimus Black] adm_:
kernels work properly on both IZS & ICS

main features: swap & zram support, undervolting, wided frequencies' scale 200Mhz-1.1Ghz

swap usage is strongly not recommended, as it causes lags in UI, zetram, otherwise, is almost a musthave.

wonna announce in advance, that dafna_v4.* would be (soon, i hope) on the latest 3.9.4 stable linux sources. ;)

dafna _v3.3:

haven't changed a byte in code - only trickstering with linaro's commandline parameters.

results could be seen by eye; according to tests dafna_v3.3 makes now on lionheart even larger figures than diana_0.3 did on performance. ;)

necessary tunings (without them rom would lag or even become unstable/freezed): lionheart, bfq, cache 2Mb, aggressive OOM, seeder, zram.

sicdezmond (from 4pda.ru) suggests that it may be usefull before installing this version to wipe cache & dalvik.

dafna_v3.2:

v 3.1 + additional undervolting of 800 Mhz.

rebuilt on the latest versions - android-ndk-r8e & gcc 4.7, theoretical and/or practical achivements of this rebuilding had to be finded yet. ;)

due to the widely known gcc 4.7 bug, wifi module does not compile properly (any help or ideas for any workaround would be greatly appreciated), but module from the previous version of dafna could be just copied to /etc/wifi (proper permissions 755 had to be checked/set, of course).

overall feeling: it's much quicker and has lower power consumption than dafna_3.1.

necessary tunings (without them rom would lag or even become unstable/freezed): lionheart, bfq, cache 2Mb, aggressive OOM, seeder, zram.

dafna_v3.1:

v3 + upper limit changed to undervolted 1.1 Ghz according to lgeob's (from 4pda.ru) idea of frequency's changeling.

necessary tunings (without them rom would lag or even become unstable/freezed): lionheart, bfq, cache 2Mb, aggressive OOM, seeder, zram.

dafna_v3:

v2 + tuned undervolting + changing of lowest frequency to 20Mhz (also added upper limit 1.1Ghz is recognized, but not used by the system).

necessary tunings (without them rom would lag or even become unstable/freezed): lionheart, bfq, cache 2Mb, aggressive OOM, seeder, zram.

Historical review:

dafna_v2:

v1+ undervolting of wifi + disabling ipv6 + disabling ethernet in company with a pair of not needed TCP protocols.

dafna_v1:

based on diana_v.3 by Huexxx, swap + zram, light undervolting after lgeob's ideas, disabling of most of the kernel's debugging.

It works on trasmusic ics rom too.

Btw how to set up those tunables?

I know about governors but dunno which app is compatible with the kernel.

Edit: nvm I just tried trickster mod and it works ok for now.
[LG Optimus Black] adm_:
any app you like. ;)

the simpliest and easiest way is to set it up with the init.d scripts (seeder, of course, had to be only installed).

as to the apps - android tuner, android trickster, no-frills CPU (for example) - most of them can tune partly required, but none can tune all mentioned.
[LG Optimus Black] DaemonOnx:
Great job mate.I'll test it on Trasmusic v30f.Hope that oc is stable

[LG Optimus Black] Grakel:
The kernel source is published in the original thread, on those russian forums.

[LG Optimus Black] BlackPie:
Hey ur back! :p
[LG Optimus Black] adm_:
just guessing, what you do not know how to use - hyperlinks or browsers? ;-P

there is one already (it's there from the beginning of my post, btw), try to follow it and read carefully - URLs are in plain english, if you haven't heard it before. ;-P
[LG Optimus Black] Grakel:
No need to be so sarcastic.

And no, there is no direct link to github in your OP.

The only link present in your OP is a russian webpage, where there IS a link to github.

So I know, it was just two clicks to get the github link, but could you post it also in the xda thread OP? Its not such a hard task, isnt it? =)
[LG Optimus Black] adm_:
no, it is, if you wonna check some mental abilities of others. ;-P

[LG Optimus Black] adm_:
it's not an answer on the question - it sounds just as blah-blah-blah of a foolish child. .

tell exactly, please, what rom you are using, which version of the kernel, what governor, what scheduler, cashe size, sizes of swap and zram (if they are used), full content of init.d and autostart, OOM settings, launcher, exact names and versions of "the apps/games which are force closing" - any bug become a bug only when it can be reproduced with te same settings of the system.

I want to play games like subway surfers , temple run 2 etc, but in stock ICS based rom i cant because it lags too much.

Can anyone confirm about this kernel with ics roms that can't lag.

And if anyone is using other stock based rom and kernel then let me know.
[LG Optimus Black] adm_:
set all the recommended in the OP parameters and you'll play your games.
[LG Optimus Black] BlackPie:
Now you are being nice.Great Improvement!
[LG Optimus Black] garzacorporations:
It wold be great a tutorial with how.to set the tweak and with which programs. I've nofrills CPU and ROM toolbox pro. I only found governor\io and sdcard set to 2mb.
[LG Optimus Black] adm_:
all settings except seeder (which is a programm and may be only installed) could be set either manually from a terminal's command line (for a test purposes), or as init.d scripts (for everyreboot use).

all settings except zram (which required inid.d script for proper functioning) and seeder could be also set from android tuner (do not know any other programm with the same functionality).

[LG Optimus Black] kinjal:
With Dafna 3.2 battery drain is not acceptable.
[LG Optimus Black] adm_:
up to you - i'm simply enjoying 0.6% per hour in sleeping mode.

if you've got more than 0.6 - try to follow instructions in OP. ;-P
[LG Optimus Black] Grakel:
Battery drain is quite the same than the original ics kernel for me. Pretty much acceptable.

Other than that, I managed to get all the settings tuned as you mentioned in the OP, and got to say the rom flies now.

Only I had some SoD's with dafna 3.2 (device was not waking up), lionheart governor, row scheduler and entropy generation activated (no oom and minfree memory tweaks).

Now with 3.3, bfq i/o 2mb cache and tuned OOM/MinFree values for memory I still had no SoD's.

Will report if I get any SoD's with the latest version and the settings you suggested in the OP.

Edit: May I suggest a little overclock to the gpu?
[LG Optimus Black] adm_:
it was already tried and rejected - as it makes a real DRAIN ;)

thank you for response.
[LG Optimus Black] Grakel:
Oh didnt know it was such a battery drainer.

And wanted to ask something else, how is the f-sync in this kernel? enabled I suppose?

If so, is there any way for disabling it? I would like it to be disabled, since I never noticed any data loss, but of course I noticed a higher response on I/O.

Also, if this is not too much talking, I wanted to mention that few people from xda (example: faux123 from the nexus forums) got a way to implement asynchronous f-sync control. You keep the data integrity but having a small piece of the boost you get when disabling f-sync.

Not like Im pushing you to implement or work harder on this. You are already doing such a great job, and I appretiate it. Thank you.
[LG Optimus Black] adm_:
no, it is not.
[LG Optimus Black] Grakel:
Awesome, thanks =)
[LG Optimus Black] hare89:

[LG Optimus Black] patelumangv:

why did this happen?

now it happens everytime i install dafna except v3. V3 works fine.
[LG Optimus Black] Duumke1:

[LG Optimus Black] hare89:
i have just installed 3.3 on the latest trasmusic ics and installed trickster and android tuner ,and i am wondering is it possible adm that you include in your next versions some kind of script with this needed settings so we dont need to install three different apps...
[LG Optimus Black] adm_:
dunno, you are the first one from more than three quaters of a hundred peoples installed dafna_v3.3 who report such a case.

suppose that something is totally wrong in your rom's settings.
[LG Optimus Black] adm_:
nope, i can do it, but do not want to - it will be not only kernel's building, but partly a rom-making, which i wonna to avoid.
[LG Optimus Black] cleitonpp:
draining battery so fast...

7% per hour on IZS at the moment

[LG Optimus Black] adm_:
it drains more, than 3.2, but still reasonably - 0.9 procent per hour in sleep mode, check & clean your autostart.
[LG Optimus Black] Grakel:
Yesterday I had a SoD (device not waking up from sleep) with v3.3 and all the settings as specified in the OP.

Is this only happening to me?

Other than that I keep the kernel for a couple of days now, seems pretty darn good.

[LG Optimus Black] adm_:
there were some similiar reports and i'd even got same case myself (during sdcard's speed test).

there is an idea, that this version dislikes low energy (less than 30%) - but still collecting statistics, cannot tell for sure.
[LG Optimus Black] adm_:
Huexxx, what's up?! second miss in two days - check, pls, whom you were answering with quoted above invective... ;)

as to me, never had said any word about your kernel - it's simply old and outdated, and needed badly a proper optimization.

...try to understand, that time did not stopped forether this january, when you'd finished it... ;)

and i know a couple of guys (at least) who are looking forward (as i do too) if you could find/invent a workaround with linaro's bug of not compiling modules properly...
[LG Optimus Black] hare89:
I experienced to on 3.3 same problem with no waking up :( everything was fine until this problem...
[LG Optimus Black] Grakel:
However, as he said, you MUST publish your sources inside the OP. Not under a link to a russian webpage. He is in his right to ask for the direct link to the sources, and more if you are using his kernel as a base.

And of course it takes 1 minute to copy and paste the link to the OP.

And please, dont take this again as an aggression, its just about xda rules and what is fair/what is not.

Other than that, this is a great job, I can feel the improvement, and I can see it didnt deteriorate the battery lifetime.

Hi.

I am using TRASMUSIC V30F (based in IZS) latest version ROM. I`ve tried this kernel (both v3.2 and v3.3) for last few days with recommended setting (set using "Trickster" ans "Seeder") and I had three major issues: :cowboy:

1. Sudden SoDs - screen won`t wake up and I have to reboot by pulling out the battery. Also when this happens when I press power button screen is of but keys are lighting, and when I repress power button the light goes off...

2. Problem installing applications from Playstore (keep getting "Package file is invalid" error) and very often problem with installing applications from local storage. Tried full wiping and reflashing but nothing solved the issue. Also tried this to prove my self that it is up to kernel: I installed fresh ROM (TRASMUSIC V30F latest), then booted into system, and tried installing from local storage and from Playstore and it all worked just fine. Then rebooted into recovery, installed this modded kernel and rebooted and retried installing apps and problem reappeared...Then I reflashed stock TRASMUSIC ROM with no wipes and it all got back to normal and functioning state.

3. Games keep getting FC (like Subway Surfers and Temple Run 2) - Tried same thing as mentioned above regarding installing apps, and on stock kernel it works just fine, and on this modded games get FC.

On positive side, interface seems much more fluid when using this kernel and in game "Beach Buggy Blitz" (one of few that work fine) perfomance seem to be improved with decreased amount of lags. :angel:

Hope my little contribution will be useful. :D And of course to developer: keep up the good work! :fingers-crossed:

Cheers :highfive:
[LG Optimus Black] adm_:
this one really exists on 3.3 - the only known now solutiion is to install each app separately and retry reqursevely (in case of error) untill happyend.

as to the installation of already downloaded apps from sdcard. it works fine.

the best joke about this was: kernel is too quick, google had to rewrite it's Market in accordance with kernel's requirements. ;)
[LG Optimus Black] adm_:
2 whom it may concern

there are a link in the OP that lead to original posting, where github address of sources is mentioned, and a direct link in somebody's comment in the thread.

moreover, i specially put my github's nick in my details on xda.

and i wonna left OP exactly the same way as it is now (if a link to github would be added to OP by moderators, i'll delete the thread and all would had to search for newer versions in russian forums).

bye.

UPDATE: and don't fool anybody, GPL requires only to publish/open sources (mine were opened from the beginnig), this is a pure xda invention, which i will never obey (partly from esthetical reasons of an artist).
