[Galaxy Ace II Android Development] ChronoMonochrome:
Hi,

Possibly the standalone kernel version doesn't support LOS 14.1 (I didn't really use LOS 14.1 that long so I can't be sure).

It had support for the CM 14.1 but since the rebrand of CM to LOS the compatibility could break.

I would just suggest using a standard kernel that comes with LOS 14.1.
[Galaxy Ace II Android Development] Mohammad Jebreeni:
Ok thanks Chrono :) What do you think the best ROM for our codina is right now?

Have a nice day / good night! ;)
[Galaxy Ace II Android Development] ChronoMonochrome:
Have a look at the LOS 13.0 https://xdaforums.com/galaxy-ace/ace-2-develop/rom-lineageos-13-0-t3937238

It's not maintained at the moment, but could still running quite well (for such an old phone with a limited amount of RAM).
[Galaxy Ace II Android Development] Mohammad Jebreeni:
Hey again [MENTION=5695278]ChronoMonochrome[/MENTION] :D , Hope you're having a good day / night.

Would it be ok to ask you for updates regarding the dual-boot feature? Also, most links are broken. I, and the whole community I believe, would be very thankful if you could provide us some new links as it's not that easy to know which kernel version (for instance) is the best to use for the dual-boot feature.

Thanks in advance! :)
[Galaxy Ace II Android Development] ChronoMonochrome:
Hey, haven't been here for a while. I will check out the links to see what are down.

I'm pretty sure the main link to the kernel and the related stuff is still up:

http://xda.mister-freeze.eu/XDA-files/ChronoMonochrome/kernel/

I'm not working on this anymore.

Anyway, what kind of update is necessary here?
[Galaxy Ace II Android Development] brewzip:
Hi Chrono, do you know about a method to make an Android 5+ rom pass SafetyNet? a2n+cm11 seems to achieve this goal, but its kernel is likely not portable to higher OS versions.

I'm trying to pass it on your testing cm13 rom, but any rom other would be fine.
[Galaxy Ace II Android Development] ChronoMonochrome:
It's possible to bypass SafetyNet by installing Magisk.

This is not compatible with our device kernel format, however S2 got it working.

You need the Android build enviroment to prepare such a kernel.
[Galaxy Ace II Android Development] brewzip:
Yeah, I know about magisk and red about the problems with this device. Unfortunately trying with the build environent is not a viable option for me.

I tried myself something with various stuff already available. Flashing your AOSP UltimateROM 6.0.1 with your last 5.10 kernel, disabling debugging and removing su from /system/xbin, I managed to pass at least the Basic Integrity, but the CTS fails. It should depend from the settings in /system/build.prop like the fingerprint (tried from stock) and Selinux, which I think it's impossible to set as Enforcing, since your kernel has it disabled, isn't it?

Any idea if I can proceed from this point? Anyway, I don't really care about having root or particular roms, I simply need any setup above KitKat that can pass Safetynet completely for this phone.

Edit: With the J5 (android 6.0) fingerprint data it seems to pass all checks, using the app Safetynet Test, while Safetynet Helper gives an APIError:7. Weird.
[Galaxy Ace II Android Development] Grindur:
can somebody reupload?
[Galaxy Ace II Android Development] ChronoMonochrome:
Okay, I'll try to revert some changes in MCDE.
[Galaxy Ace II Android Development] manthes:
If i am the only one with this problem don't bother. I will stay with previous build.
[Galaxy Ace II Android Development] ChronoMonochrome:
It's not first report about screen tearing, i think it may be caused by some changes that i made at 25.07.
[Galaxy Ace II Android Development] danny19901:
I have a strange problem I don't know what's causing it either latest liquid smooth 4.4.4 or Latest EXT4 kernel but when I download apps they work fine but after a while they fail to try open until I uninstall and redownload I'm not sure what's causing it anyone else had similar issue ?
[Galaxy Ace II Android Development] manthes:
No problem for me. I am also using latest liquid
[Galaxy Ace II Android Development] danny19901:
OK its weird as I did clean full wipe flashed LS the Gapps then EXT4 Kernel but I downloaded a few apps they where working fine but after a reboot I always get android is upgrading optimising apps then they don't work anymore until uninstall and redownload also had this problem with candykat when I updated the kernel and ROM
[Galaxy Ace II Android Development] ChronoMonochrome:
I don't think it's related to kernel. Kernel manages only low level things.
[Galaxy Ace II Android Development] ace2nutzer:
@ danny

have u repart. the emmc ?

What are u using for Runtime ? ART or Dalvik ?
[Galaxy Ace II Android Development] ChronoMonochrome:
R1

Version r1 has been released!

I highly recommend this update. :) Looks like poor memory management finally has been fixed in this build! While phone in deep sleep he does not kill every process that he can as it was before. I only can guess which change affected to this (maybe this https://github.com/ChronoMonochrome/Chrono_Kernel/commit/98c0ca56bd054a21bab583c336559ab60dde5465 or new zRam driver, or something else, really don't know). Just in case, my settings: 200 MB zRam, min free - (10419, 13117, 15815, 18700, 21399, 26608). Update for cm11 and codina p coming soon :) See github for more details.
[Galaxy Ace II Android Development] danny19901:
I always use dalvik I use link2SD Pro I have a 32GB SD Card with 2 partitions 4GB and 26GB I have all my apps set up but I don't understand why my phone keeps trying to optimise apps I have no mods on that should do that but I think its fine now as its only optimising google apps now like maps, gmail and haven't had any FC's for a while
[Galaxy Ace II Android Development] gRaB@:
On CM11 r1 build I can't change min CPU from 100 to 200 mH, it allways back to 100. And there is no 1000 mHz but 998 mHz.
[Galaxy Ace II Android Development] shoxieJESUS:
998 MHz is 1000 MHz
[Galaxy Ace II Android Development] ChronoMonochrome:
Can we do not pay attention on it? :D as I said here was a reason for it. Because sometimes min freq stucked at 1 GHz freq. before I renamed 1000 -> 998 MHz.
[Galaxy Ace II Android Development] muop_92:
R1 version works good so far :thumbup:
[Galaxy Ace II Android Development] manthes:
With r1 screen tearing have been dissapeared or at least isn't visible for me
[Galaxy Ace II Android Development] RootPegasus:
I will try R1 Version for Stockrom :)

Thank you for your hard work :)
[Galaxy Ace II Android Development] danny19901:
Using R1 on Liquid smooth 4.4.4 works awesome

As for the screen tearing problem people have been having I noticed any screen tearing
[Galaxy Ace II Android Development] ChronoMonochrome:
Glad to hear. But afaik black screen bug still presents in this build?
[Galaxy Ace II Android Development] manthes:
If you mean for recovery yes. I used twrp kernels but at this time i went back to cm 10.1 because i want flash player and filmon app to work.

For lockscreen it happens rarely in previous builds.
[Galaxy Ace II Android Development] zizoumadrid:
i have bootloop and my phone still at galaxy ace 2 logo with last build kernel twrp
[Galaxy Ace II Android Development] el_polilla1990:
tearing is really resolved in this build, good job ?

[Galaxy Ace II Android Development] str3tch72:
I don't have bootloop on TWRP R1 version. AOSP.
[Galaxy Ace II Android Development] judas1977:
TWRP for 4.3.1 (ext4) works fine here. It's start of testing but kernel is really promising
[Galaxy Ace II Android Development] mydevilroot:
So far for me the newest version of kernel is good (ext4 cwm) running on vanir rom at 1.25 GhZ lagfree - sioplus. The speed is awesome, but i am having some bugs. For the first sometimes the screen is black when i am trying to unlock it (have to wait few sec for screen response) or trying to recive a call. Also dunno why my battery is draining very fast. From 100% to 10% in 6h. The last issues is minimal freq. I set it to 200 MHz, but it's changing itself to 100 MHz after locking the screen. Anyway thanks for the good job on the kernel. It's awesome. I can send a logcat in the next days, can't do it now, sorry :(
[Galaxy Ace II Android Development] ghinzu85:
First of all, amazing job man!!

I have not read 'bout this but... I've been having problems with clock at night. In morning alarm never go on so... I fall asleep everyday.

Thanks a lot and once again... amazin', amazin' job!
[Galaxy Ace II Android Development] zizoumadrid:
what is the deferent between twrp and cwm ?
[Galaxy Ace II Android Development] danny19901:
Not much apart from UI difference but TWRP I would say is more user friendly and also shows time and battery etc... Unlike CWM which doesn't also easy to wipe in TWRP and flash ROMs quicker
[Galaxy Ace II Android Development] Nathanabrahams:
I think there is still some memory leakige
[Galaxy Ace II Android Development] ChronoMonochrome:
Thanks for report and sorry for changing to 100 MHz itself. I'll provide workaround for it(I think I can't just revert some changes those cause this bug) or I'll just remove 100 MHz step.

But where exactly?? I never noticed memory leak for a several weeks(I noticed some leakage with SLQB, after this I switched to SLUB).
[Galaxy Ace II Android Development] xo.en:
TWRP has brightness control, while cwm doesn't..
[Galaxy Ace II Android Development] manthes:
Deep sleep works fine for first day and after 7 hours battery drop from 56% to 51.

I am using ext4 kernel for 4.2. I know that i have asked for just one build with twrp but if you can make another one for 4.2 without screen tearing it will be fine
[Galaxy Ace II Android Development] ChronoMonochrome:
Sorry, I thought i already uploaded this build. Yesterday i've made build for 4.2 with twrp, but looks like i forgot to upload it. I'll upload it asap.
[Galaxy Ace II Android Development] AndroidOwnsAll:
Which build is the best for AOSP?

I'm currently using the 12/08 build and for some reason the battery drains a little quicker than the stock kernal of AOSP
[Galaxy Ace II Android Development] acrocosm:
I get similar behaviour, concerning deep sleep, with AOSPA and CM11 kernel too. So I don't think this kernel is the culprit

TWRP is great but I don't like it because it can't see he external SD. Is this solvable?
[Galaxy Ace II Android Development] judas1977:
I have access to both storages in twrp recovery (latest kernel), maybe it need to be mounted before, don't remember
[Galaxy Ace II Android Development] ace2nutzer:
I remember u that all CM Versions and even Stock JB have this Bug with min. cpu freq !! But zwliew have fixed this Bug for a couple of Weeks.

Just ask him..:cowboy:
[Galaxy Ace II Android Development] ChronoMonochrome:
Already fixed. I thought I can't revert change that cause this derp. I've made workaround for locking any min freq, and after just tried to revert commit that cause bug - without any consequences. Sorry I at once did not do :)
[Galaxy Ace II Android Development] Bilgets:
R1 and R1.0.7_4 what's the difference?
[Galaxy Ace II Android Development] ChronoMonochrome:
Only workaround for changing min freq itself.

Type

echo 200000 > /sys/kernel/cpufreq/cpufreq_force_min_limit

It will forces min freq @ 200 MHz.

It will be useless in next build because random changing of min freq has been fixed.

upd. btw, I noticed big drop in I/O performance since R1 has been released. Fixing right now!
[Galaxy Ace II Android Development] danny19901:
Silly question but has anybody noticed big battery drain when using WiFi compared to data

On WiFi I lose 1% every few mins on data I lose 1% every 20 + mins

PS here's my battery stats

I can't charge my phone due to broken charger port I have to swap batteries
[Galaxy Ace II Android Development] mydevilroot:

f2fs kernel does it work carbon rom ?
[Galaxy Ace II Android Development] danny19901:
It should work fine although I was using EXT4 kernel with carbon not that long ago on latest build of carbon and performance was pretty bad not sure what was causing it
[Galaxy Ace II Android Development] gRaB@:
[MENTION=3138903]danny19901[/MENTION] What's your rom? Because 2 d and 2 h on batery is very good.
[Galaxy Ace II Android Development] danny19901:
I didn't get that much battery its because my charger port is broken so I have to battery swap when dead I'm lucky to get 3 - 6hrs out of a battery but my rom is liquid smooth 4.4.4 latest build
[Galaxy Ace II Android Development] gRaB@:
@up Now i see. I had one time 2d on battery with this kernel from 09.08 on CM11 TC, and for me is the best version.
[Galaxy Ace II Android Development] zizoumadrid:
but i'm with stock rom 4.1.2 with chrono kernel how i can get novathor

does novathor work for me with stock rom 4.1.2

thank's
[Galaxy Ace II Android Development] danny19901:
I haven't used stock ROM but it should work just put novathor apk in system/app and allow all permissions on reboot it should show up and should work or install it and use titanium backup to make it a system app let me know if it works [emoji1]
[Galaxy Ace II Android Development] danny19901:
I know this ain't the place but does anyone know a good ROM with decent customization and pretty good battery just liquid is killing my battery also when will we see 4.4.4 kernel update with 100Mhz fix ?
[Galaxy Ace II Android Development] Bilgets:
Sometimes clock didn't update.. Anyone got this problem?
[Galaxy Ace II Android Development] j8hnb:
Latest cm11 is good :) just set cpu 200mhz instead of 100 and disable BLN in nova settings for now.

Which ROM are you using this kernel with? Maybe try settings/display daydream and tick clock...?
[Galaxy Ace II Android Development] manthes:
I had it once but i don't remember with which rom it happened. I have used liquid 4.4,cm 10.2 and now i stay with 10.1
[Galaxy Ace II Android Development] fluffi444:
Same here. But dont know exactly when or why... But happens quite often...
[Galaxy Ace II Android Development] Bilgets:
I'm on PA 4.5. It happen usually at night when I didn't use my phone.. I left my phone for overnight charge usually

Yeah I recently found out that is the problem why my alarm is not ringing
[Galaxy Ace II Android Development] zizoumadrid:
thank you so much for your help but i can't find novathor settings apk how i can get it ?

My device catch bootloop on TWRP version of kernel. On CWM version it boots normally.
[Galaxy Ace II Android Development] denisq:
The r1.0.7 is not (yet) available for cwm. Will it work if I use the twrp version instead (flashed with CWM)?

If not, is the echo workaround for min freq a permanent fix or temporary (until reboot) one?
[Galaxy Ace II Android Development] ChronoMonochrome:
It's not permanent. You have to use init.d script until next version.
[Galaxy Ace II Android Development] borkins:
Thanks, danny for sharing the NovathorSettings.app! I tried it on JB 4.1.2, but I got "Error parsing the package".

Looks the app isn't compatible with JB.

thank's for your sharing but i'm getting same result as [MENTION=5151049]borkins[/MENTION]

i can't install it and when i put in system/app and allow all permissions and make reboot still no result no app in menu
[Galaxy Ace II Android Development] danny19901:
Oh sorry to hear have you tried normal install and using titanium to make system app if that don't work I would suggest trying to find a custom ROM that's on same firmware that has novathor and then pulling it from that I will have a look see if I can find a method for you's
[Galaxy Ace II Android Development] zizoumadrid:
i think only installed app can make it system/app with titanium

the problem is can't install novathor
[Galaxy Ace II Android Development] judas1977:
NovaThor settings won't work with 4.1 ROMs at all, no matter of installation method

But with stock kernel I never had clock and message issues like now - even with almost completely greenifyed system (Pro version).....

This sounds for me that something goes into a "too" deepsleep - Or even needed proceses were killed.
[Galaxy Ace II Android Development] ChronoMonochrome:
It's may relate to interactive(It's not "original" interactive, it's imported from zwliew's kernel from 6 July or so. Maybe I should import it from TC kernel, but it haven't project butter). I haven't any problems with Abyssplug 100/1200 MHz.

I never faced this problem all time of development this kernel. But I got a few reports about this a few months ago.

Btw, here is a small preview of next build:

http://d-h.st/ia6 (4.4.x, twrp)

http://d-h.st/hBT (4.4.x, f2fs)

I've tried to fix black screen bug on s6d, I need some tests, because I don't know if it works. There is also a new feature, as has been requested

You can set min/max CPU freq. for screen off(for example):

echo min=100000 > /sys/kernel/cpufreq/screenoff_cpufreq_limits
echo max=400000 > /sys/kernel/cpufreq/screenoff_cpufreq_limits
echo on > /sys/kernel/cpufreq/screenoff_cpufreq_limits

Don't use it with Interactive, I got some sound shuttering with these settings(still trying to fix).
[Galaxy Ace II Android Development] manthes:
I have s6d driver but i am using cm10.1. If it is the same for you i can test (you probably mean black screen at CWM)
