Running CM12.1, I flashed the kernel, then downloaded Stweaks. Unfortunately, Stweaks installed (check box was checked by default!) Supersu. That led to a mess, cause I wasn't able to grant root to any app anymore.. tried something, but in the end was forced to restore Nandroid backup.

Was just unlucky, or should uncheck immediately that "install Supersu" option in Stweaks?

I may be blind, but I re-read the OP, and found nothing concerning STweaks, apart for "beware, you must know what you do as they are advanced options". I'm fine with experimenting on my own, but would like to know if I need to let it flash its own supersu or what, as it messed up my ROM when I did it first time..

Flash SuperSu 2.46 zip.
[Galaxy S II Android Development] kai1313:
when using dori, im always still flashing/download supersu apart just to make sure it'll do its work

because install root from stweaks tab menu cant help me once i try to use it, only root check that fixed for now i think(it once said no root even you install supersu/root from cm devel on the previous build)

that`s rigth , i'm according with you.
[Galaxy S II Android Development] keepasa:
Did you perform a cache & dalvic clear after kernel flash? Are you installing R remix after a factory data wipe? I previously had instability issues with older remix and older kernel betas. However dori beta 5 together with R remix July 23 update works quite well with me currently. I did a factory wipe, wipe system, flash RR ROM, flash tk pico gapps, SuperSU, reboot, checked OK, rebooted back to recovery to flash dori beta 5, and then wipe cache an dalvic, rebooted, all OK, I then went ahead and restored my apps with titanium backup.
[Galaxy S II Android Development] DaveKing:
would be nice to have support too to the DU Rom 9.5, that was released yesterday. The ROM is very very stable and could have support by this excelent work by gsstudios. But I'll stick to that rom, and gonna miss some good features of DorimanX until it happen.

Farewell. ;)
[Galaxy S II Android Development] Dr AM:
DU is AOSP so don't think it will be supported soon
[Galaxy S II Android Development] Saber:
Don't worry, once I have some more time to work on the kernel, I will work with lysergic acid to add support for other roms. (He is quite busy with the release of official cm12.1, so my debugging efforts are the only slowdowns to this goal).
[Galaxy S II Android Development] DaveKing:
This is really good news. Just because DU is a lot stable. Everyone should see DU Team work. One very stable Rom indeed. But a lot of DorimanX features are missing like some governors and shedulers that works a lot better in S2 and are very battery friendly. Tripndroid and Hyper for example. Well, just my opinion. But we can't have everything, right! ^_^

Cheers and lot of beers! =P

Important announcement

Guys, I'm moving back to Linaro 4.9 toolchain. I feel that the UBER toolchain experience was good, but I felt that we needed the optimizations for our kernel to run even smoother. Battery life is another talking point, we'll see if this change will also improve this too.

regards, gsstudios.
[Galaxy S II Android Development] DaveKing:
from what I have seen from DU kernel, that is very stable, kernel is compiled with Linaro v4.9.3 (hard float version) with arm-cortex-a9 and vector floating point level3 optimizations. And the ROM itself has the UBER 4.9 optimizitions from what it tells. And the kernel is indeed very smooth and battery friendly.

Am i the only one facing this problem ? Just Curious
[Galaxy S II Android Development] kai1313:
i assume that lag because we need get the right configuration(with explorable OC, OV,UV the cpu and gpu) that suit with the rom we used, its a custom kernel so it need some tuning

I think in that time nokia rullez in the mobile scene. Well, maybe your chip and mine, and other too, are the first ones ever made. The beta ones. LOL I think it's kinda impossible this chip were made in that time. But maybe was, and that year was the first manufacturing of it. But I doubt it, because of the 9 years time between the manufacturing and the first models using the chip itself. Well, the chip can be used to more gadgets than Smartphones... Even military must have used it first... Don't know. It's a scandal if it's true. =P But a controller like this one, have a lot of power to be used in that time. That is for sure. ~_^

[Galaxy S II Android Development] Saber:
Today, I present to you build b006. I have switch to linaro 4.9 now, no more UBER for all future builds. There were some changes to stweaks regarding to descriptions and units. And lastly, more work was done to get ad-hoc networks working (still not working though).

[Galaxy S II Android Development] kai1313:
sorry if im wrong

but when using stock cm kernel, i got everything smoothly, which is stock kernel is definitely suit for its ROM

anyway, the Linaro build has been released

[Galaxy S II Android Development] DaveKing:
with this kind of living... you betcha! ;) I don't need to buy another phone yet, past four year and half....so I think we have a winner. ^_^ Everygame runs perfecly, no matter if it's emulator PSX or android itself. With the right configuration of course. And I don't feel that the new quad or octa phones kill our device. Just for one reason. 20000+ in Antutu is something that a S3 (quadcore) have difficult to achieve. And I have achieved 20800 with this baby with LP in it ROM CM and DorimanX kernel, 1.5Ghz and oc 400Mhz in gpu, governor Hyper and scheduler tripndroid. So I think it was a well spent money in this case. Because I disagree with some policies of Samsung , will lend me to buy Xiaomi next time to test they phones. =D But S2 will be in my heart forever as the best smartphone ever made and sadly, very soon forgetted by Samsung.

Cheers mate.
[Galaxy S II Android Development] DaveKing:
Sadly I cannot test it in DU Rom. So I have to wait for compatible kernel release. But must be good, cause people aren't complaining. :P

[Galaxy S II Android Development] DaveKing:
What did you do in Stweaks. What did you change? In Cortex I didn't touched. In CPU settings just undervolted 25mV from default voltage, but some achive 50mV UV. CPU behave better if more colded. High temp 65+ celcius normally is bad for this cpu. The same for GPU. For example, the default voltage for 267 is 1050mV, and I undervolted 50mV and it run excelent. In the case of 400Mhz depends of the chip...my does that frequency others don't. Mine run at 1200mV, when the default is 1300 or 1350mV at that speed. But the device at big stress get a little hot in the screen....normal. But just because of the 1350mV of 1.5Ghz of CPU and the 1200mV of 400Mhz of GPU. At the same time is a lot of power.... Well. If you tell me where is that default_profile file I can try to put it here if I find it... But in my ROM now, I don't have Stweaks installed, cause DorimanX doesn't work in with DU. But if the file still there I share it. No prob.

overall, its reliable for now
[Galaxy S II Android Development] kal4metal:
Gsstudios, first of all thank you for your great work! Your efforts in keeping DorimanX kernel up to date are awesome, but sadly I have a problem that made me revert back to stock kernel. First of all, I installed your kernel over the unofficial gustavo kernel by lysergic acid. I installed Beta 5, trim enabled. Being Voltage group 2 i UVed -25 each cpu step and -50 each gpu step. At first my phone felt smooth on UI and battery usage was good. After a while I started seeing a lot of FCes, lags, SODs so I reverted to default settings. The only thing that I changed again was gpu voltage. I undervolted gpu step three and four to stock voltages as mentioned in stweaks. After a little while i got the same results. Then beta 6 was released. I reverted to default stweaks settings and flashed kernelwipe by hawkercore without wiping cache. Then I did not touch anything in Stweaks. Again, at first it felt smooth and okay, but after a while it got laggy again, i was getting FCes and a lot of SODs, especially while charging! I love your work on the kernel and I feel sad for not being able to use it. Does anybody else have the same prob? Am I doing something wrong? Please help! Thanks in advance, regards!

you are fail here. This kernel have especially Recovery thanks [MENTION=5074262]StanTRC[/MENTION].

Go out here and use DU or SlimLP Kernel that have TWRP and will lucky.
[Galaxy S II Android Development] Noctis Lucis Caelum:

You have headphone amplification and the headphone sound level setting (this is the one you need to set)

What ?! He just had issues supporting ext4 and needed help :)

Yes I said use TWRP to flash the ROM for the FIRST time cuz had issues with cwn and philz and these issues wasn't present in first nightlies but in these new nightlies

And cuz Dorimanx doesn't support ext4 I didn't use it to flash the ROM so I could be as far away as possible from any issues :)

Can anyone comment on b006 vs b005 or UBER vs Linaro impact you felt?

For me it does feel more fluid and less buggy as the dev mentioned in the OP
[Galaxy S II Android Development] kai1313:
+1, indeed smoother

but did you get tether(hotspot or usb) problem with it?
[Galaxy S II Android Development] DroidNforcer:
Yes feels faster and smoother with Linaro.

for the battery im not a good tester right now until I fix my usb port.

For the tethering I did some test to share thru Bluetooth my wifi internet.

It works but only when you connect from the other terminal not when you tap connect on the phone and not always.

Sometimes it connects and the other terminal thinks it getting internet but doesn`t nor the extra squared white bt icon apears on any only the normal gets white.

I don`t know if this is normal behabior or not but Here are some logs just in case.

The normal tethering cannot test right now. I`give it a try when I buy some credit for the sim. I usualy dont use the phone the normal way.

Regards.
[Galaxy S II Android Development] kal4metal:
Done that and still have the same problem. I didn't touch anything in STweaks and I still got FCses, SODs etc. Especially when I use apps lile facebook, messenger, chrome. I got a SOD while charging overnight with all the apps greenified! Can someone please help? Thanks!
[Galaxy S II Android Development] Jack122:
im using an app called easy thether pro. it costs 8 euro. it works with windows 7. and it claims to work with more platforms.
[Galaxy S II Android Development] DroidNforcer:
I believe the new WiFi drivers has issues with hidden ssid networks.

When the AP name is shown it connects normaly but after hiding it, the phone no longer sees it.

I remember now that this happened on stilescristi`s build aswell, and for the way it ignores the hidden AP I think it may have relation with the Ad-hoc network not connecting issue.

[Galaxy S II Android Development] DroidNforcer:
Mmh... you know that he is not our employee, right?

Besides this are unofficial personal builds that he builts for him self and he share them with us out of his good heart, and are like alpha/beta releases.

Many people did not like personal builds and stayed with last computoncio/cybernetus builds wich works fine and can be used instead of stock kernel.

Another solution could be use an older release without the new drivers or maybe you could ask him kindly what you need.

[Galaxy S II Android Development] wdevil12:
I know bro I know. Im not ignoring the fact that these builds are personal and again Huge Thanks for the hard work he have done, Im just saying instead of fixing ad-hoc network things, we should improve stability for the existing functionality...
[Galaxy S II Android Development] Saber:
I'll see what I can do in the next build. I am 100% going to revert back WiFi drivers on all of my kernel builds. (My new thought is that people who previously had WiFi access should have WiFi access on newer builds). This time, I'll do everything from scratch, not updating from some else's source. The build should be up by this weekend.

Trimmed & Non-Trimmed Kernel

Could you explain the differences between Trimmed & Non-Trimmed Kernel?

Thank you.
[Galaxy S II Android Development] lukss12:
Trimed kernel is the one which has the trim feature enabled. Trim feature is designed to boost emmc, it makes possible to mark blocks from the emmc as erased in a way that normal erase won't. Some S2 emmc had a bug on firmware that broke them when using trim. Now the trim enabled kernel has the patch to use trim on non-bugged emmc.

//wrong//If you have a known bugged emmc the kernel will "execute" trim command but it will do nothing.//

Edit: this kernel is patched also to make bugged emmc trimable too

Thanks to noppy22 for the info
[Galaxy S II Android Development] :
This is not true. The patches enable even chips with emmc bugs to be trimmed as well. In practice, the trim enabled kernels(and trim commands) are safe for all chips in the S2 and work as originally intended as long as the correct patches have been implemented
[Galaxy S II Android Development] lukss12:
I'm not going to argue about this because my knowledge could be wrong. I prefer any kernel dev to clarify this.

Edit: But as far as I know Samsung patch was disabling trim for certain emmc by model name with an special flag on code.
[Galaxy S II Android Development] :
Sorry dude not trying to argue. But trim is safe, and works for all emmc's with the correct patches. :)
[Galaxy S II Android Development] lukss12:
Yes, for sure trim enabled kernel is safe for any emmc, but I don't really know if it is trimming bug-affected ones or it just bypass the command.
[Galaxy S II Android Development] :
I trimmed my S2 not long ago. I have the VYL00M chip, which is brickbug affected(insane chip). My results were -

/system 194162688

/data 1491095552

/cache 96260096

/preload 519643136 bytes trimmed

(fstrim from terminal commands)
[Galaxy S II Android Development] lukss12:
VYL00M devices are reported to have secure-erase bug fixed on fw 0x25. Can you share your fw revision? So we can be sure if trim is working in an affected device?

I got the info from http://wiki.cyanogenmod.org/w/EMMC_Bugs#Samsung_eMMC_secure_erase_bug where they say the fix for "superbrick" is blocking functionality from kernel.
[Galaxy S II Android Development] :
FW 0x19.

For more info have a read of [MENTION=4141005]Lanchon[/MENTION] 's trim thread HERE. He was one of the pioneers of safe trim on this device and helped develop the methods and patches on the older CM kernels. His patches, as well as the samsung patches have been implemented on several other kernels(including [MENTION=5811506]gsstudios[/MENTION] kernels), and I'm sure he would say they are all totally safe by evidence of no-one having bricked their phones with his fixes(as long as they are compiled with correct patches) As always it is the risk of the person using trim, but a lot of users with brickbug affected chips have succesfully trimmed. :)
[Galaxy S II Android Development] DroidNforcer:
I always trim the EFS patition aswel. Never had a problem but, am I gonna die??? [emoji12]

If somethong were supposed to go wrong, I guess I got lucky!
