There is change made in the latest beta for dual rom. If you really want to try it, just flash something earlier than b8, clone first rom to second rom, then reboot, and check you can get into your second rom. Then wipe your first rom and install. When finished, chose swap first and second roms (I think thats the menu option name).

I can confirm that if you dont have any 2nd rom and you flash a clean rom to dual boot. It doesnt work. It flashes but cant be detected at boot.
[Galaxy S II Original Android Development] PedroMRP:
You must first follow this guide and when you have installed the second rom you can use install zip to second rom option

http://xdaforums.com/showpost.php?p=24233085&postcount=2

Please read more careful the changelog... gokhanmoral explicitly write that you must have a second rom installed to that feature works
[Galaxy S II Original Android Development] Visentinel:
I had abit of a look arround and I can't really figure out where secondrom/system is, I know it's a hidden partition but I'm trying to figure it out by looking at how much space there is left in a few areas.

Where did you find the space to put the secondrom/system?
[Galaxy S II Original Android Development] pilgrim011:
Okay, I formatted secondrom data and second rom cache with Total commander, installed zip via dual boot menu, but second rom is no longer detected on boot... Secondrom folder in internal sd card is completely empty...

Gokhan:

I have a huge suspend_backof kernel wakelock, sometimes I notice that my phone doesn't enter deepsleep but gets somewhat stuck in a low freq (100mhz in this case)... then I have to enter airplane mode and deactivate it and it restores for a while, always with the wifi activated.

Is there a way to reduce this? or is there a way to effectively locate which app could be causing it? (not a trial and error method because I have a lot of apps instaled, maybe an app that logs which app runs in a certain time or something similar?)

Attached is my BBS dump file

[Galaxy S II Original Android Development] gokhanmoral:
people who cannot flash rom directly to second rom & format data+cache:

there is a missing part which is fixed it in rc1if you do not have /sdcard/.secondrom folder it is not created automatically.

I recommend you to clone your primary rom just for once and then flash & format secondrom_data+secondrom_cache.

that kind of tiny problems are fixed in rc1.
[Galaxy S II Original Android Development] rlorange:
I just discovered this for myself. As always you are onto these small glitches before I had a chance to see if anyone else had reported it and then do so myself.

Anyone looking for the perfect Sammy from to use with cm9. Epsilon v2 is very good so far. Has a great OTA app built in. Very fast too.

I have an issue with nandroid backup in cwm recovery. My .android_secure folder is stored in internal memory. If I choose to backup to external sd card nandroid tries to find the folder .android_secure folder on external sd card. The only solution so far is to move the folder via adb to external sd card before backing up. Durring restore the .android_secure folder is restored to external sd card either and must be copied back manually to internal storage. Any easy fix on that?
[Galaxy S II Original Android Development] bokil:
A starting point

Flashed v3.2b8.

Before flashing,

Changed voltage settings to default in NStools (i think you need to reboot for voltage settings to become default).

Reset EXtweaks at recovery.

After Flashing,

Made following changes (rest were default)

In Extweaks:

GPU:

GPU FREQ STEP1 =133MHz

GPU FREQ STEP1 =267MHz

GPU FREQ STEP1 =267MHz

GPU VOLTAGE LEVEL 1 = 850mV

GPU VOLTAGE LEVEL 2 = 950mV

GPU VOLTAGE LEVEL 3 = 950mV

BLN:

BLN=Ticked

Notification timeout= 3mins

BLN EFFECT= Breathing

MISC:

Ondemand and sio

In NStools:

Tweaks:

Active Scheduler=sio

CPU:

Governor: Ondemand

Min CPU freq=200 Mhz

Max CPU freq=1200 Mhz

Volt:

1200Mhz=1200mV

1100Mhz=1200mV

1000Mhz=1100mV

900Mhz=1100mV

800Mhz=975mV

700Mhz=975mV

600Mhz=975mV

500Mhz=950mV

400Mhz=950mV

300Mhz=950mV

200Mhz=875mV

Settings:

Set on boot=ticked

Nstools service=ticked

Will test and tweak further. Will report any successfull changes.

These settings are looking stable...will test with lot of applications and inform back.

comments added: may test the following settings next:

1200Mhz=1200mV

1100Mhz=1175mV

1000Mhz=1100mV

900Mhz=1075mV

800Mhz=975mV

700Mhz=975mV

600Mhz=975mV

500Mhz=950mV

400Mhz=925mV

300Mhz=900mV

200Mhz=875mV

hopefully they will work :)
[Galaxy S II Original Android Development] Ramelov:
I've done it differently and I think it's a simpler way. I've just created manually folder /.secondrom on sdcard. Then just formatted cache and data (it takes some time) of secondary rom and flashed secondary room directly from dual boot options. Everything works perfectly.

Funny how we chose similar methods for the breathing effect. At first I just wanted to make the LED buttons dimmable and needed are readout from the regulator. Then I had the idea to implement breathing as well.

But the hardest part was to understand 2500000 was the minimum value for the regulator. I was about to get crazy grep'ing my brains out, until I finally did a trial and error :)
[Galaxy S II Original Android Development] bokil:
During the discussion of BLN few pages back somewhere, GM had said that min voltage for led to be visible is 2.5mV
[Galaxy S II Original Android Development] gokhanmoral:
I have just checked your implementation. you are right, they are very similar.

"great minds think alike" ;)

and it is really nice to see people who don't need someone else's work to have a new feature in his kernel... that I respect and why I find your repositories worth following.

great work.
[Galaxy S II Original Android Development] myfluxi:
I started with breathing late saturday evening but but initially failed miserably because I didn't schedule a timer. Had to read up on it on those great IBM pages, love those guys for their documentation.

Love your work, too (even if it's a bit crazy sometimes :))

Can anyone give suggestion for best rom for this kernel,I use now CM9?
[Galaxy S II Original Android Development] bokil:
There are a lot of good roms.

You can try wanamlite...i am loving it.
[Galaxy S II Original Android Development] gokhanmoral:
I won't give you an answer but if someone gives you an answer try this:

- someone tells you XYZ ROM is the best for this kernel

- you go and ask in XYZ ROM thread "which is the best kernel for this ROM?" and users will tell you some other kernel than this one

- you go and ask in that kernel's thread about the best ROM to use with that kernel and you will have an answer different than XYZ ROM.

- and finally if you ask in the other ROMs thread about the best kernel to use with that ROM you may get siyahkernel as an answer. and everything will start over :)

boot into second rom and delete /data/.siyah/*.profile

What do you mean with reset and disabled?

The initial reset resets the bln_steps used for the pattern.

If not i will lower your 1100mhz to 1125mv, your 900mhz to 1000mv, 700mhz to 950mv, 600mhz to 900mv.

If you will try, try one by one. Because later you not will know what step crash your system.

800mV for 100mHz seems to be the lowest I can do on my device.

I agree.

Unique freqs without default are using is 300 and 400mhz. The rest 600, 700, 900, 1000 and 1100 are unless.

TapaTalk Gnex Galaxy Sii
[Galaxy S II Original Android Development] bokil:
Use also NSTools for missed call notification.

If you have any other BLN software then better uninstall it.

Extweaks and Nstools is sufficient for BLN.

Your settings in Extweaks seem to be ok.

Have you tried rebooting after the settings?

May be some one here will give you a better idea.:)

I am trying to find out the same for ICS/Siyah/ 18 Steps.

It gave me a 2 days battery life for single charge in GB (Checkrom/siyah)
[Galaxy S II Original Android Development] james_lpool:
sorry for the noob question, i have recently put the andyx v12 rom on my s2, and now i am looking into updating the kernel for the first time.

im really interested in this siyah kernel but i am not sure if i am wanting it for the right reason as i dont know a great deal about it, from what i have read its great for overclocking / underclocking, not sure if im interested in the dual boot right now.

aside from that i dont think i want to over / under clock anyway so would i see much improvement is using this kernel, does it bring further performance gains anyway, smoother scrolling etc.. better battery life.. and does the kernel use stock voltage / cpu settings as default so im not installing it and automatically overclocking my s2?

i have downloaded gs2 wiper which i am lef to believe is good to use before installing the kernel, is that a much or do most not bother?

so what do people see as an improvement in there day to day use of their phone that they would say makes it worth using this kernel?

i noticed on the site where siyah is hosted that this version is currently in beta and a new version has been coming out every other day, being new to this would i be best waiting till the final release is out or is it very simple to just install new versions as they come out anyway, if i was going to i think i would just use cmw anyway, so it sounds very easy.

last question :) if i do update to siyah will i be able to update to the next version of andyx rom without any issues and just the same as usual?

anyway sorry for asking such basic questions about it, its just things id like to know before i update to it.
[Galaxy S II Original Android Development] Rawi666:
As bokil said NSTools are needed for missed calls.

However, samsung stock SMS app will not work with BLN at all.

You have to use another sms app like go sms pro, handcent, etc if you want to have bln notification for sms messages

interesting. very good for dual-core mode..

but still, I think you should try with some agressive thresholds such as load_h 25 load_l 10 settings with freq_min 200

(by the way, if you set load_h higher than 50, you will have single core mode. I think some of you are using 70-75-80 values. I should limit that threshold to 50)

Dual Boot

@PedroMRP -- no offence intended, but insisting that we follow the original instructions (x2) is no help when the kernel command/script in the latest Siyah beta is flawed... several of us mentioned this including GM

Anyway followed this suggestion above -- works perfectly! I now have both Omega variations (Sammy+AOKP) running via Siyah.

I do however, have a question, if the kernel is shared, does this means changes made via exTweaks on the Primary ROM are automatically applied to the Secondary? or are there 2 separate configs?

Please don't bite my head off -- I've only had this working for 40 minutes, so still playing/reading/playing some more... ;)
[Galaxy S II Original Android Development] karlesg:
Which are the stock Samsung defaults for load_h, load_l ?
[Galaxy S II Original Android Development] gokhanmoral:
kernel is shared but extweaks settings are not.

they are kept in /data/.siyah folder which is different for both roms.

I am thinking about using internal sdcard to keep those settings (/sdcard/.siyah folder) and use in both roms.

but maybe having two different settings is better, for a gaming ROM with GPU@400MHz and a general purpose ROM with GPU@100MHz..

I haven't decided yet.
[Galaxy S II Original Android Development] gokhanmoral:
load_h0:30/load_l1:20 are samsung's default.

There is no best rom for this kernel because it is difficult to have an answer. How many S2 users will have how many answers for you. ha ha. :) Perhaps only have best rom for you not for this kernel . But okie, yeah I can tell you one of the best kernel for all roms is SIYAH.

Right ! Guys ?
[Galaxy S II Original Android Development] rlorange:
I think keeping them separate is best personally
[Galaxy S II Original Android Development] gokhanmoral:
sorry, but no.

I have downloaded that kernel several times in GB days.

after you told me to check it I have also checked it's changelog.

I've never found anything special in that kernel. and more interestingly, people were thanking him for introducing smooth scaling parameters in Galaxy Note forums...

until someone points at something interesting in that kernel that I cannot find elsewhere, I will not download his sources because last time I checked it was one of those "no new feature until someone else implements something new" kernel.

maybe he has found a good set of patches to apply by spending lots of time and cherrypicking from other repositories, but I don't have that much time to figure out what they are.

and those "fantastic at deep sleep" feedbacks should be verified by a full cycle. I never trust short time evaluation of battery life. I have reasons to believe that battery readings are not always correct. I can make your phone lose 1% in 2 hours with screen-on but then it will lose the rest in another 2 hours...

if the ROM comes with a kernel (likely) you will have to reflash siyahkernel after flashing the rom.

but if you flash ROM using CWM recovery (in zip format) to second ROM (using dual-boot options menu) it will not flash kernel and you won't have to reflash siyahkernel back.
