I'll take a look at that when I have time :D thanks for the suggestion bro, I think I might have to remove OC until I figure it out lol
[Galaxy S 4 i9500 Android Development] :
Update!

v2.0

- Reduced A7 OC to max 1.3GHz

- big.LITTLE optimization for A7 and A15

- Attemp to fix some problems in last version

- Optimize for speed instead of size

- Removed many useless stuffs

However, I forgot to bring my S4 with me in my vacation so the v2.0 is untested. Backup boot is recommended before flashing
[Galaxy S 4 i9500 Android Development] Toggie:
My s4 with kernel v2.0 dont booting(im wait 15 min)...=(
[Galaxy S 4 i9500 Android Development] :
I forgot to disable selinux lol :laugh: v2.0 is reuploaded with selinux disable guys should be booting now
[Galaxy S 4 i9500 Android Development] Toggie:
i don`t see any changes at booting...
[Galaxy S 4 i9500 Android Development] :
Hm weird, where do you get stuck? samsung logo?
[Galaxy S 4 i9500 Android Development] Toggie:
yes, at samsung logo.
[Galaxy S 4 i9500 Android Development] :
Ok it should definitely work now, can you redownload v2.0 and tell me if it boot?
[Galaxy S 4 i9500 Android Development] lamhoang:
It stuck at samsung logo before but I just downloaded lastest and it went pass :fingers-crossed: now optimizing apps
[Galaxy S 4 i9500 Android Development] milindlokde:
Version 2.0 is working fine. Stable/no random reboot and good battery life. Thanks. [emoji106]

Not tried previous versions.

Using GearCM 13.0. It had issue with battery life and random reboots.
[Galaxy S 4 i9500 Android Development] :
Small update!

Just some small changes today :D

v2.1

- Fixed init.d script thanks [MENTION=6172162]Skrillex2911[/MENTION] for reminding me :victory:

- Fixed some small bugs
[Galaxy S 4 i9500 Android Development] daogiahieu:
In the #1, you said using "Gear Recovery".

I am using TWRP, is it any different between them ?

Can i use twrp without any problem.

I know you recommend use gear recovery but i just want to ask why ?

thank you to bring this kernel for our S4.
[Galaxy S 4 i9500 Android Development] andreluizbarbieri:
v7.1 in RR work very well, thanks.

now I see some off-line cores after reboot synapse with some cores disabled. Thank you so much!
[Galaxy S 4 i9500 Android Development] Ngadhnjim:
hehehehe going to install now :good:

REVIEW FOR TOUCHWIZ V7.1

Thank u bro. BUT after booting with first flight rom,

Nothing else work.

If you u try to set up synapse parameters, every app force closes... tired of pressing ok ok button.

So, needs more fixing.

Back to voltaque v15.

Thanks for v7.1 :)

We'll wait for stable one. :)

Cheers!
[Galaxy S 4 i9500 Android Development] Ngadhnjim:
this verzion for tw is ok but only need to change cpu freq from 1800 to 1500 and min to 150 ,problem is to 1800 i got screen freeze to 1500 no more freeze ...

yes synapse give err close so u need to go to setings applications and clear cache and data of synapse ,for me worked fine
[Galaxy S 4 i9500 Android Development] nikulbhatiya:
1. Already cleared synapse data before flashing kernel.

2. I set max freq to 600 :D So 1800 or 1600 is far away from me. (I use only a7 cores to save my precious battery ;) )

3. Anything else?

Which rom u using bro?
[Galaxy S 4 i9500 Android Development] Ngadhnjim:
im using ff rom based on tw

lionheart gov dosent work...

this kernel seems to work only with default setings...i set governor to intelliactive and restart and init.d screept automaticlly set to default
[Galaxy S 4 i9500 Android Development] MostaphaHida:
V7.1 boots fine on GCM but there's a front camera bug sinceV7.0 anything else fine till nw still testing...
[Galaxy S 4 i9500 Android Development] braulio_holtz:
tested again with this version, strange, again only works with the device charging

GearCM (with GearRecovery), nevermore 7.1.

When the boot does not work, happens to black screen
[Galaxy S 4 i9500 Android Development] :
Seems like FCs are different for ppl i guess? I have many google play fcs and cant open some google apps

What happen when u open front cam? Weird cuz i didnt change anything about camera

Hm so blackscreen problem is still there, thanks for reporting
[Galaxy S 4 i9500 Android Development] MostaphaHida:
FC even wiped app cache nothing changed same pb exist
[Galaxy S 4 i9500 Android Development] braulio_holtz:
I do not know if it helps, but what I did now.

I turned on the phone with the USB cable on Computer - worked regular boot

I disconnected the USB cable and restarted the machine - blackscreen

I turned on the phone again with the USB cable on Computer - worked regular boot - generated a logcat (which I think is cleaned every restart) - kmsg too
[Galaxy S 4 i9500 Android Development] Ngadhnjim:
yeahh cant install app from google play when i do accept they say google play need to close

after some restarts my system ui stoped working dont show status bar icons ,battery clock etc...
[Galaxy S 4 i9500 Android Development] Aakrep:
v6.7 sometimes freezing and I think its governors are unstable [MENTION=5963088]jwchen17[/MENTION]

Is v7.1 stable?

BTW gpu is freezing and not smooth with 532, 600,640mhz.... And cpu is never work up to 1600 mhz with all governors
[Galaxy S 4 i9500 Android Development] ktouy:
So far 7.1 stable for me, i ran some stress test and i think that random blackout maybe due gpu i have it locked now at 350 and no problem whatsoever... If i leave it 500+ i get random blackout.. The only way to boot it again on 7.1 its to reflash 6.7 and then 7.1 again...

Also front camera not working...

I will use it all day and check if it is stable enough...

[MENTION=4521615]JWach[/MENTION]en17 thanks for the support and the hard work!!
[Galaxy S 4 i9500 Android Development] andreluizbarbieri:
v7.1 is very stable. I set core numbers, GPU clock, idle state agrresive and everything work and I get no freeze or reboot. Nevermore means that you never more change of kernel...
[Galaxy S 4 i9500 Android Development] :
Thanks for all feedbacks and supports :D updates will come later since my sat test is tomorrow ;) have a nice day guys
[Galaxy S 4 i9500 Android Development] ktouy:
Good luck with that test dude! ;D
[Galaxy S 4 i9500 Android Development] ahmedalihadi:
bug

storege does not work for me on tw
[Galaxy S 4 i9500 Android Development] nikulbhatiya:
True.

External SD automatically unmounted from the first boot.
[Galaxy S 4 i9500 Android Development] andreluizbarbieri:
For me SD card always mounted but really front camera don't work. Background data with problem and it keep off, and why my synapse have many "has failed"? (I already clear data of synapse). Then I return to 6.7 but it have still many 'has failed' in synapse.
[Galaxy S 4 i9500 Android Development] :
Update!

v7.2

- Fix Touchwiz FCs here and there

- Fix no SD-card in Touchwiz

- Fix some synapse codes, remove wifi power control

- Reduce default max A15 freq to 1600MHz

- Increase default max A7 freq to 1500MHz

- Added an option to control A7 max freq in synapse

- Added init script to set values for Touchwiz version

TW tested by me no more FCs. CM and RRemix are untested but should boot fine. For Touchwiz version, please wait for a while during the first boot and then go to synapse to press the tick to apply values, screen may freeze and device will reboot but the 2nd time it boot, it should be fine.
[Galaxy S 4 i9500 Android Development] Ngadhnjim:
man thenks for tw v. i will install and let u known for everything

everything work ok but only when i go in synapse to i/o menu some say failed but thats not make problems ...only my phone work fast
[Galaxy S 4 i9500 Android Development] braulio_holtz:
GearCM is making boot normally.

remove wifi power control - I was seeing that my wifi this disconnecting from time to time, entering the 3G, I think that will solve the problem.

Cortex Brain is offline, it just shows how online If it is running a task?

Brain Cortex-background-process = enable

Crontab is enabled with all fields, but click on Check Jobs and shows how "no data--no data no-data..."
[Galaxy S 4 i9500 Android Development] Ngadhnjim:
need info from anybody ,i dont known problem coming from nevermore or light weight kernel (im on tw) i test those 2 on same time ,my camera application do photos but when i go to galery it is empty ..test cammera app in that kernel ...
[Galaxy S 4 i9500 Android Development] Ngadhnjim:
i test tw verzion of this last 7.2 ,camera application dont work ,when u make photo not showing on galery ...
[Galaxy S 4 i9500 Android Development] Jorgetudo_98:
I'm not sure if I did something wrong, my s4 is not booting, it reaches the "optimizing apps" screen and randomly shuts off in the process. I'm on RR 5.7.3.

---------- Post added at 09:59 PM ---------- Previous post was at 09:53 PM ----------

Ok so it happens when it tries to optimize some google apps like gmail or keep, and the list of apps it has to optimize gets smaller with each try, so it is optimizing the others... Any ideas?
[Galaxy S 4 i9500 Android Development] Aakrep:
I have a bug on RR with v7.2 bro...I challenge Gpu mhz as only 700 mhz and after 30 seconds screen is distorted :eek::eek:

BTW front camera is not work
[Galaxy S 4 i9500 Android Development] andreluizbarbieri:
Someone has also many "failed" options in Synapse (I already clear data and reboot)? If I run other kernel, synapse show few "failed's" but with This kernel most options fail (like set cpu governor show "SOoptionList has failed")... Please, [MENTION=5963088]jwchen17[/MENTION]

Show this error: "you must be rootchmod: /sys/devices/system/cpu/..." but it is rooted (your Rom RR5.7.4_11pit)! I can set some options, like voltage but I can't set many options because it failed...
[Galaxy S 4 i9500 Android Development] krasCGQ:
700 MHz is too much. Let the maximum clock to 640 MHz.
[Galaxy S 4 i9500 Android Development] kongacute:
Using voltage settings in battery profile(volt 15) + interactive governor make phone freeze and reboot. 3-4 times and i back to volt 15 now.
[Galaxy S 4 i9500 Android Development] :
about camera ill try to fix it, but for front cam, u guys have to test front camera for me since my front cam is broken :(

I think you install some mods that conflicts with synapse configuration, thats the only explanation why u get failed options in synapse, i only have the wifi power failed but thats because i didnt fully remove it, may be try flash supersu again
[Galaxy S 4 i9500 Android Development] :
Update!

v7.3

- Fix governors causing phone to freeze and reboot

- Fix camera and vibrator for CM version ( need test )

- Add ARM optimization build flag

- Use GearCM IR blaster driver

- Enable ondemand to use up to 1500MHz in A7 cores

- Set default hotplug values

- Remove leftover synapse codes

Need feedback on whether camera is working now on cm-based rom. Have a nice day guys :D

p/s: I added a section in 2nd post for frequently asked questions and known issues. Take a look at it when you have time :D
[Galaxy S 4 i9500 Android Development] ahmedalihadi:
please fix

i cant set govenor in tw version it say (Soptionlist has faild)
[Galaxy S 4 i9500 Android Development] :
can you guys at least tell me the rom and be more detailed please? im using firstflight here and no problem whatsoever so i dont know what problems are u guys experiencing. What governor are you trying to set to?
[Galaxy S 4 i9500 Android Development] kenji1996:
Using madgit rom. flash 7.3 first thing is the sim card cannot detect... i try 3 carrier only one works. need to switch back stock kernel only work. the tick is keep appear everytime i open synapse.
[Galaxy S 4 i9500 Android Development] Aakrep:
Yes bro 700 mhz is extreme and dangerous ... [MENTION=5963088]jwchen17[/MENTION] as for me, you must delete to 700 mhz gpu setting :confused:
[Galaxy S 4 i9500 Android Development] batuhur:
Hello [MENTION=5963088]jwchen17[/MENTION]

I installed this kernel yesterday and there is already an update today! Keep up this awesome work

Only issue i encountered is that whenever I open synapse there is that tick right there on top. I checked all tha tabs in synapse and found out that GPU speed changes everytime I open synapse. Whan can I do about this? It doesn't cause any freezes or issues like that but its just weird.

I will report other issues (if there is) after some usage.

Thx
[Galaxy S 4 i9500 Android Development] Aakrep:
Back and front cam work on RR v7.3 but what is this message from synapse.
[Galaxy S 4 i9500 Android Development] :
Ok ill remove it

Thanks, thats because of my init script to keep gpu lower than 700 at boot, ill remove 700mhz gpu next version so ill also remove the script also :D

Could be because a syntax error when i edit synapse code
[Galaxy S 4 i9500 Android Development] kenji1996:
Phone has stopped error. cannot call andreceive call. tw version madgit rom
[Galaxy S 4 i9500 Android Development] ahmedalihadi:
thanks it works

just i deleted synapse and and rebooted and install again

and all work

thx <3

but still stuck and reboot -_- i am using octanate rom based on ale95 rom 5.1.
[Galaxy S 4 i9500 Android Development] andreluizbarbieri:
I also have same problem in the 7.3 version: "JSON configuration parsing failure". Front camera go back work, thanks. But I can't use Synapse.

RR 5.7.4_11pit
[Galaxy S 4 i9500 Android Development] ktouy:
So far no issue at all w 7.3... Front camera not only work.. But also somehow its fixed the blue tint thing was (yey!) facing since dont know when on apps like Duo and so, not camera.

Anyway geat so far!

Thumbs UP! [emoji106] [emoji106] [emoji106]

7.3V keeps rebooting.. after flashing nd phone boot ur able to use the phone normally once the screen turns off just couple mins nd can't turn it on then phone keeps rebooting...GCM version
[Galaxy S 4 i9500 Android Development] Aakrep:
V7.3 RR is very very stable and battery uses great on deep sleep...That is not have random reboot and freezing

But not using synapse now "JSON configuration parsing failure"
[Galaxy S 4 i9500 Android Development] ahmedalihadi:
plaese fix rebooting problem because it ****ed me up -_-
[Galaxy S 4 i9500 Android Development] :
hey man my kernel is not perfect and im working to fix any problems :) you made the choice to install it so it is not my fault
[Galaxy S 4 i9500 Android Development] :
v7.4

- Use latest 6.1.1 Oct 2 Linaro toolchain

- Fix synapse code for A7 freq control

- Decrease thermal throttling

- Increase default main AC current to 1800mA

- Slightly increase other USB charge source current

I could not fix call in TW version yet so if you really need to use call function then don't use my touchwiz kernel. Synapse control should be back now :) Have a nice day guys!
[Galaxy S 4 i9500 Android Development] ahmedalihadi:
sorry for my lang .. but is really perfect but i hope you fix this it not this hard >>because i used all rom and same problem >>on al95 and firstflight rebooting and dialar not work it stoped :crying:
[Galaxy S 4 i9500 Android Development] :
yeh like i said before my touchwiz kernel is not very stable right now with many bugs so i dont recommend using it for daily driver :) i dont have time yet to fix it as well
[Galaxy S 4 i9500 Android Development] ahmedalihadi:
ok thanks bro your kernel fix my phone heating problem all kernels have stuck cpu problem on 1200 or 600 or 1600

temp arrived over 80c

thanks again ;):good: :*

7.3 auto on/off cpu cores but why 7.4 is not have that capacity?
[Galaxy S 4 i9500 Android Development] :
try to increase cpu up boost to 60 and cpu down hys to 25 and see if that works
[Galaxy S 4 i9500 Android Development] Aakrep:
:confused: not happening
[Galaxy S 4 i9500 Android Development] :
Change the option from normal to economy also
[Galaxy S 4 i9500 Android Development] Aakrep:
Not happening bro :confused: I think have a problem at ondemand governor... Because cpu hotplug work only with abyssplug governor... Also, I think ondemand works now very aggressive
[Galaxy S 4 i9500 Android Development] 34xda34:
i have problem with wi-fi no connection. 3G works fine. Also tried TW v7.3 too.

And sometimes phone restarts itself :(
[Galaxy S 4 i9500 Android Development] andreluizbarbieri:
I just decrease cpu to 1500 (still A7, I hope) and some cores are offlines. Thanks, [MENTION=5963088]jwchen17[/MENTION]

Everything Works in 7.4 like synapse, camera, 3G, battery saving...
[Galaxy S 4 i9500 Android Development] Revantark:
Is this working in ff rom ?
[Galaxy S 4 i9500 Android Development] krasCGQ:
It works with TW version, but if you need calling feature, you better use other kernel instead until this one get fixed.
[Galaxy S 4 i9500 Android Development] Ngadhnjim:
tw 7.4 no wifi for me ,problem with sim not registered to network and maybe another problem ...
[Galaxy S 4 i9500 Android Development] Aakrep:
My phone is very hot with 7.4 ... Also, cpu hotplug sometimes work but after reboot hotplug not work :confused: sometimes I change to online cpu core setting then cpu hotplug works but only sometimes bro.

And, I when change governor, synapse viewed "sGeneric has failed" message
[MENTION=5963088]jwchen17[/MENTION]
[Galaxy S 4 i9500 Android Development] andreluizbarbieri:
best kernel

Works for me. My phone is cold although I decrease freq., and some cores are offlines exactly how hotplug should work.

Sorry. After I changed again governor synapse show "SGeneric has failed"
[Galaxy S 4 i9500 Android Development] vvk222:
Got random reboot on v7.4, see last_kmsg.
[Galaxy S 4 i9500 Android Development] litvcom:
I try v7.4 (NvmRR-v7.4-i9500-03102016) on RR v5.7.4 (20160925) and for me kernel is very unstable, random reboots, problem with booting.
[Galaxy S 4 i9500 Android Development] andreluizbarbieri:
Must you install this kernel with GearRecovery
[Galaxy S 4 i9500 Android Development] litvcom:
Yes, I used the latest version GearRecovery from 20160220
[Galaxy S 4 i9500 Android Development] braulio_holtz:
For me it is also unstable, GearCM13

The last commit is to fix this issue? https://github.com/jwchen1259/nevermore/commits/master
[Galaxy S 4 i9500 Android Development] krasCGQ:
The last commit just enabled 700 MHz devfreq (GPU frequency) again.
[Galaxy S 4 i9500 Android Development] braulio_holtz:
Oh yes, true, but for me it was unstable, perhaps the reason not to boot after a couple of days of use

I don't know if other people experienced unstable in the last build
[Galaxy S 4 i9500 Android Development] andreluizbarbieri:
For me, 7.4 boot normally and it haven't random reboot or freeze. In this version I can set config in synapse (other versions has problems). I'm using RR 5.7.4_11pit and GearRecovery, Just it.
[Galaxy S 4 i9500 Android Development] :
Hopefully new version will come out today, I didnt have much time during the past week. I will disable 700mhz gpu and 1500mhz a7 cpu for stability, I thought I disabled it already but I think I did some reverts so I accidentally re-enabled 700mhz. I will also remove hotplug too I guess since sometimes it stresses one core too much causing reboots.
[Galaxy S 4 i9500 Android Development] :
CM test build https://drive.google.com/open?id=0B4Mn7J1xXUWXRU00YlIwRGNkUVE

RRemix test build https://drive.google.com/open?id=0B4Mn7J1xXUWXRjVWX2lSYUZKN2s

I'm running touchwiz right now so can't test cm and rr, can someone tell me if it boot or not in cm/rr ?
[Galaxy S 4 i9500 Android Development] andreluizbarbieri:
v7.5 boot only to recovery again... RR 5.7.4_11pit
[Galaxy S 4 i9500 Android Development] :
v7.5

- Removed 700MHz freq

- Removed dynamic hotplug

- Removed Doze control on touchwiz synapse

- Returned to old build flags

- Fixed Phone & Bluetooth FCs on touchwiz

- Fixed problems with A7 max freq

CM and RR version should boot I think. Phone and Bluetooth are working now on touchwiz so I think it should be fine for daily usage :)

i figured it out :D thanks for the quick reply anyway bro
[Galaxy S 4 i9500 Android Development] ktouy:
Last two builds are unstable for me, w/moderate heavy use, like feedly, chrome, listen music some whatsapp back and forth, phone freeze completly in about ~10mins... ive notice that heat up a lot, even tho i have both little as well Big at 1200mhz and gpu sticked at 350..

I tried many governors with the exact same result

Edit: GearCm latest
[Galaxy S 4 i9500 Android Development] andreluizbarbieri:
V7.5 has good battery saving. Early version was drainning cell standby in airplane mode while this new version no drain cell standby. Screen drain only 2 mah/minute with screen on, I think that is good. My phone no freeze or heat. I'm using rr5.7.4_11pit
[Galaxy S 4 i9500 Android Development] :
Thanks guys, ill try to imrprove next ver
[Galaxy S 4 i9500 Android Development] Ngadhnjim:
TW verzion is stable ?
[Galaxy S 4 i9500 Android Development] ahmedalihadi:

[Galaxy S 4 i9500 Android Development] :
v7.6

- Used [MENTION=6589753]krasCGQ[/MENTION] script for other ramdisk compressions in AIO version

- Increase throttling for less heat

- Removed A7 overclock for stability

- Improved network and I/O

- Improved performance in general

I know that the kernel is not fully stable for now so if u don't like it and need something that works as a daily driver for you then don't have to install it :D your choice
[Galaxy S 4 i9500 Android Development] Aakrep:
This project is really good.

I believe you will be more successful brother, thank you :good:
[Galaxy S 4 i9500 Android Development] robsonsilv4:

7.6 CM working fine. Thanks. :good:
[Galaxy S 4 i9500 Android Development] lamhoang:
In my opinion, I feels like v7.6 is very stable for me, using darkness with min 350 max 1600 and uV -75mv, no reboot or freeze yet, i dont know about cm and rr version :)
[Galaxy S 4 i9500 Android Development] ahmedalihadi:
no rebooting no overheat

[Galaxy S 4 i9500 Android Development] Aakrep:
He use albe95 5.0.1 Rom... I view from his old post.
[Galaxy S 4 i9500 Android Development] Ngadhnjim:
show how ?
[Galaxy S 4 i9500 Android Development] :
battery tab, increase ac/mains input and charge current, i already increased the values so i dont recommend higher than 1900
[Galaxy S 4 i9500 Android Development] Falah Mahdi:
I flashed the Kernel on my device "cm 12.1" and my device has crashed?
[Galaxy S 4 i9500 Android Development] andreluizbarbieri:
remove the battery and put it back then turn on.
[Galaxy S 4 i9500 Android Development] Aakrep:
I have this message on synapse... BTW did you remove Doze Setting?
[Galaxy S 4 i9500 Android Development] krasCGQ:
That's because overclocking on A7 core is disabled.
[Galaxy S 4 i9500 Android Development] andreluizbarbieri:
Then v7.5 has more adjust! I keep using the 7.5
[Galaxy S 4 i9500 Android Development] :
Yes I removed it since I don't think it works properly yet but will re-add it later on. In addition, I remove A7 overclock for a more stable kernel but I did not remove the options in synapse so thats why we have those red lines but just ignore them as they are harmless
[Galaxy S 4 i9500 Android Development] Falah Mahdi:
Yeah I do that and it doesn't work?
[Galaxy S 4 i9500 Android Development] :
what version are you using? if you are using cm12.1 then please install the AIO version :)
[Galaxy S 4 i9500 Android Development] Falah Mahdi:
Can you give me the link please??
[Galaxy S 4 i9500 Android Development] Aakrep:
Thanks my friends :good:
[Galaxy S 4 i9500 Android Development] lamhoang:
Just go to the download link on the first page and find in the folder a file name NvmAIO-v7.6 and flash that
[Galaxy S 4 i9500 Android Development] Falah Mahdi:
Thanks a lot?
