power off ,remove battery and power on in cvm redo those steps .if not works flash 14.1 you have your data again.

let me know.

[Galaxy S 4 i9500 Original Android Development] Caspersky83:
Did not help. All data completely corrupted. All the problems only occur when trying to write to a memory card from a PC regardless of the MTP or Mass Storage. I do not have any idea what to do next. Only 14.1 :(

PS 15.1 works worse than 15.
[Galaxy S 4 i9500 Original Android Development] gio_b:
so,the sd did not works in a P.C ? is it exfat formatted ,and even if formatted again do not work on the P.C.???

gio..
[Galaxy S 4 i9500 Original Android Development] Caspersky83:
No. :) All writes to the memory card lead to destruction files & filesystem. Helps only reformatting.
[Galaxy S 4 i9500 Original Android Development] gio_b:
O.K reformat ,and when you flash ...remove the external S.D. always.

It was the SetupWizard who was setting it back to 1600 on service finish. I killed that off now so nothing should be touching it anymore.

And oddly enough Power Savings Mode was broken but nobody noticed. So that's fixed too in 15.2.

Can you two guys please move your discussion somewhere else?
[Galaxy S 4 i9500 Original Android Development] gio_b:
my fault

gio.
[Galaxy S 4 i9500 Original Android Development] mw86:

I haven't used the power saving mode recently so that's interesting. Seems to be working now as well, thanks.

Excellent fix Andrei.

a simple reboot solved the issue...
[Galaxy S 4 i9500 Original Android Development] sorg:
I didn't check WiFi issue on I9500, but i had WiFi issue on my I9300 when i switched from Android 4.1 to 4.3 firmware. On 4.3 i had very weak WiFi signal where on 4.1 i had strong enough. I've tracked down the problem and found issue. It's in file /data/.cid.info

I had this file on 4.1 but missed on 4.3. This file contains WiFi chip ID used by many libraries and wifi framework. This file re-creaded by macloader service. Because i've disabled selinux and other (non-working because of custom ROM) cryptowares, macloader service became disabled (because of system property didn't set) and thus .cid.info was absent. If you come to 4.3 through upgrade, then file remains from 4.1 and problem won't happen. So, i've rearranged init.rc script to start macloader and problem has been solved.

As i've told before, i didn't check it on i9500 yet, because i've upgraded directly from 4.2.2 to 4.3 without wipe (like on I9300).

[MENTION=4745870]mw86[/MENTION] should able to help u more than anyone...
[Galaxy S 4 i9500 Original Android Development] cmd512:
No such thing as ideal settings. If there was, there would be no Perseus kernel, you'd use a kernel with zero settings, like stock.

The whole point of Perseus is so that you can change / modify / customize the settings to your needs. No two people's preferences will be the same, so it's absolutely pointless to ask.
[Galaxy S 4 i9500 Original Android Development] devilsdouble:
I don't think so. Everything needs a starting point or reference and I just asked for that! If you can't help that's absolutely alright.
[Galaxy S 4 i9500 Original Android Development] cmd512:
Really, you actually bothered to mention starting point?

What do you think the default settings after you flash Perseus are for? Those ARE your starting points!
[Galaxy S 4 i9500 Original Android Development] 7OOKA:
i totally agree with you that these stuff are mostly user dependant, but im sure theres some settings\customizations that may reduce lags, ofcourse this kernel is not laggy but theres some minor lags noticed with opening some apps
[Galaxy S 4 i9500 Original Android Development] mw86:
I would say Andrei could help a person's setup more than most and perhaps Chainfire or any of the great developers. They're surely are far more qualified users than I. :) The stock setup as CMD512 mentions is pretty top notch as is.

Most app load lag depends on where the resources are stored and how they are stored for an app. Between cache and dalvik cache with odex, deodex each having different performances, locations of the odex and even the data or obb files where they are stored as system/user apps on internal SD or system or even stored on external SD by any means of link2sd, app2sd or any such including the built in function of the latest ota.

DevilsDouble if you have left power save on it would have slower app load times but besides that complete stock install of tw latest firmware runs very fast. If on a custom rom and none of the above sounds to be causing slow loading then I would look into the custom rom defaults and if on aosp nothing is guaranteed to be the fastest on our barely documented hardware.

---------- Post added at 08:03 PM ---------- Previous post was at 07:40 PM ----------

The discussion thread for all these off topics :) give Andrei a break :) he is such a great developer he often checks his thread for kernel reports from users. This just makes it all a lot more tedious and time consuming which he surely would like to get right to the needed info. If trying to discuss a setup please use the discussion thread.

No need for any back and forth about asking for user settings it's clear some users never stray far from the explored and some try everything themselves but for the sake of helping users just pleasantly ask for help there in the discussion thread and users who can help should be the only replies.

[Galaxy S 4 i9500 Original Android Development] devilsdouble:
Sorry pal I still don't get you! Or you didn't get my point!

Anyway as I see this is a dev topic and as I am still new I should ask for this elsewhere rather than crapping this topic and the follow ups.

[MENTION=4745870]mw86[/MENTION]: I love this kernel, that's why I visit this topic once every week, I really doubt if anyone ever gets that!

Anyway, I was a long time user of Android Rev HD by Mike on my Note 2, and that was one hell of a super smooth ROM, and all with Stock kernel. Then I bought this phone and now that ROM is not there I am all on stock ROM. Also I previously found that there was a governor called 'interactive' with which the device was very smooth, to be honest both on-demand sec and user preset gov in this kernel is nowhere near as smooth as interactive.
[Galaxy S 4 i9500 Original Android Development] mw86:
The ondemand-sec gov is actually pretty efficient. for a more interactive feel turn the touch booster CPU minimum to your a7 Max for smoother interactions with elements at the slight cost of higher use of power on the a7 cores while touching the screen. With the description of your preference battery is not that important. Also do the same for the button booster in QOS section of synapse. Set your A7 Max you had set in the first part of Synapse. Don't set in QOS higher than that value in the first tab on the left. The governor scales up from there fast if needed.

Having a slimmed rom could be good if you have a lot of extras that come with the GS4 still installed.

On a debloated setup I don't see any lag through menus as they pop up or load immediately. Interactive is an okay governor but for placing CPU where it needs and should be based on load Andrei's custom setup does far better than interactive because you don't necessarily hit the max a15 next unless needed using a7 cores vs a15 cores for basic tasks saves you a lot of power. The power chart for the mhz on both cores is posted back in the thread.
[Galaxy S 4 i9500 Original Android Development] stassano:
I downloaded the latest Wanam rom but am bothered by the battery drain of kcompcached... which as far as I could investigate seems to be swap and I further confirmed this with running the free command on terminal emulator. I thought switching to Perseus would fix it but it has not.

Is there any way to disable kcompcached / swap? I do not want swap, my phone is fast enough to do without.

I installed perseus 15.2 everything is working whenever i take my battery and turn on the phone it says my sd card is blank or has unsupported files.whats the solution.i am using transcend class 10
[Galaxy S 4 i9500 Original Android Development] gio_b:
First try in the pc if the files are stkll good.

Flash always with sd card out .

If files are goods , read my previous thread.

Giovanni.
[Galaxy S 4 i9500 Original Android Development] mw86:
Well to elaborate on Gio post, if the files are gone and you read from another device still gone likely when you installed if you had hit factory reset in recovery it can delete external SD so like another user if I ever use those options I remove SD perform the formats and insert SD and install.

Now if the SD had the install files for the kernel it obviously still had the files before install and boot. Definitely check from another device if they are there though it is very likely then an issue with the SD card and the kernel as you suspect if the files are still there. It will take checking that though to know.

BTW please for helpful info what format is your external SD card?

The previous issues we were working out were less format related as Andrei said than actually transfer rates the class 10 cards run could be the issue.
[Galaxy S 4 i9500 Original Android Development] olimjon:
The files are there when i flash adam kernel back.whenever i flash perseus it shows blank sd. restarting device solves it but there is a strange issue it shows some of my images on my sd like this and i have formated my sd to exfat,ntfs and fat32 but it didnt solve the issue

[Galaxy S 4 i9500 Original Android Development] devilsdouble:
Thanks a lot. But I couldn't quite get it. Could you please explain the part I had bold? I don't know what touch booster is! Do you mean I need to set CPU min freq to 1200 MHz as 1200 MHz is the set A7 freq? Also what's button booster? Under QOS section I see two sections, Touchscreen and Touchkeys, and three option under each, which one should I change there?
[Galaxy S 4 i9500 Original Android Development] mw86:
For Touch screen and Touch Keys set CPU boost frequency to 1200 mhz correct these are only a7 frequency. I use lower than stock but this will make your UI manipulation faster.

---------- Post added at 07:06 PM ---------- Previous post was at 07:01 PM ----------

When the last few test kernels were around it helps those who have issues test the different ones for a fix. Maybe the class 10 speeds are still giving trouble. There could be an issue with full speed and our device. All I can say is be available to test if Andrei posts any tests. Limited test hardware can't solve compatibility without more user input. There were test kernels related to SD issues back some posts before official alpha 15.2 or 15.1 was posted.
[Galaxy S 4 i9500 Original Android Development] devilsdouble:
Okay, thanks so I changed those two values. Anything else needs to be changed? No need to think about battery life, it means nothing to me.

PS: The CPU boost freq under Touch keys were already set to 1200 MHz by default!

Thanks for help.
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
The sound issue is not related to kernel, as far as I'm concerned and saw over the last few months, I can assume it has to do with the stock recovery kernel image. Just download the repacked Philz I put up for download several months ago. You will also get a faster recovery boot with that.
[Galaxy S 4 i9500 Original Android Development] ipsuvedi:
As I experienced, both TamirDa and Andreilux are saying right...I think its neither Kernal related nor Rom related...yes it may cause bug when Preseus kernal and certain Recovery combined

There may be some kind of conflict between Presus kernal and certain Recovery, otherwise this kernal is Excellent :)
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
It talks about Adam kernel only having the issue, which has had the issue for several weeks on a prior version. As I just said, the problem is completely unrelated to the kernels themselves but with the discrepancy between recovery kernel image and boot kernel image.

Dear [MENTION=2739548]tamirda[/MENTION] and [MENTION=4167023]AndreiLux[/MENTION] I have used only peseus kernel on my device with tamir's rom, arrow, crash. never wanam. And having this sound problem. If I go back to fillz recovery will it stop.? Or maybe TWRP? Anything other then samer's?

Did I get it right? Because its annoying!!!
[Galaxy S 4 i9500 Original Android Development] cmd512:
Sounds like to me all of you with sound issues did the hokey and complicated full wipe install when going from 4.2.2 to 4.3, which means you had to use that Samer recovery.

Instead, Andrei provided a very simple 3 step non-wipe install method that allowed you to keep using the previous 4.2.2 compatible Philz recovery with 4.3. With this method, I have never had a single sound loss occurrence.

I can tell you for a fact this issue has nothing to do with Perseus kernel. If you suspect the recovery, then just flash the latest one from Philz (4.3 compatible) and test, it's not that hard!
[Galaxy S 4 i9500 Original Android Development] dingo99:
Thanks. did that a moment ago. I was surprised to see it might be a recovery issue.

About full wipe, I always do that, no matter which rom I move from. In this case it was stock 4.3 after customized 4.2.2 one. And then customized 4.3.

I'll wait and see, it takes time between sound issue to another.

Do u have some more technical explanation how recovery can affect normal booting?

I'm still thinking audio issue can be related to SELinux(or some security services related to SELinux)/TrustZone misbehave on custom kernels. Issue may happens because some service starts earlier or too late. Kind of racing condition because of SELinux/TrustZone.

Now I saw Andrei mentioned a repacked Philz he posted for download however when I do a search in this thread no such post can be found, do you know where it might be?
