Here's a quick link to the Siyah kernel over in the i9100 forums. Everything as far as information about the kernel should apply to our phones except the obvious (battery charging steps, anything with the home button, in other words strictly hardware difference related points) as he now has made an i777 kernel version.

http://xdaforums.com/showthread.php?t=1263838

This kernel should get posted in the development thread by someone willing to keep up on all it's changes as the Siyah kernel seems to get updated all the time. Unfortunately once I heal up from surgery I won't have the time to be able to do that.

[AT&T Samsung Galaxy S II SGH-I777] gr8hairy1:
Yes it is compatible with all stock roms, cm7 roms, and MIUI roms (both 2.3.4 and 2.3.5 variations of all three)

Yeah I've read that at 1.6 it crashes..its best to stay at 1.5..

The CWM .zip will not download via phone browser, and when downloading from a windows 7 (IE browser) PC it successfully downloads but when flashing it says the package is bad. I think he needs to reupload it or put an MD5 checksum in place.
[AT&T Samsung Galaxy S II SGH-I777] wesbalmer:
For stability, I ran a setcpu stress test on my phone all morning at 1.6 (nearly blew up my battery) and had no issues at all on conservative governor.

My mistake, it did not transfer from dropbox correctly.
[AT&T Samsung Galaxy S II SGH-I777] kevtn8:
I agree with everything you said. Siyah also gives me more varied governors to play around with or tweak for diff circumstances. Gokhanmoral is also using the latest sources from Samsung in his kernel. People who are complaining about lag or jerkiness with Siyah needs to watch their voltages if they are UV. I had mine set a bit too low, bumped it up a notch and now everything is so smooth even when one of my profiles kicked in and my phone running at 800 mhz. Stability wise has been awesome as well. :-)
[AT&T Samsung Galaxy S II SGH-I777] Kadin:
I'd love to come back but I was having some odd FCs that I never had before or after with Entropy's DD. I also had the weird issue where every now and then, when I attempted to lock my phone by just pressing the power button like normal, it would insist on taking a screenshot instead. I'd have to click home a few times or go into the app drawer and come back out to get it to work properly.
[AT&T Samsung Galaxy S II SGH-I777] kevtn8:
The screen shot issue happened to me once but never came back after one simple reboot. As for the odd FCs, try reflashing the kernel after you run the kernel cleaner script and if necessary, clear cache and dalvik cache then reflash Siyah kernel. It also happened to me once or twice but never again after those simple steps. See if that helps.

Edit: There is just one app that still occasionally FC and that's my AIM messenger which also FC as well on Entropy's DD so that's a wash with both kernels.

I am running it with miui works like a dream. Fast and stable. Overclock it to 1.4 or 800mhz the days I don't bring my extra battery.
[AT&T Samsung Galaxy S II SGH-I777] EnemyOfGlaDOS:
I flashed it, booted fine.. checked it out. Booted into recovery to flash back the nightly.. and couldn't read my sd card.. rebooted phone and used RM to try and restore a backup and ended up in android system recovery and "installation aborted warning" (which i thought was a little odd) and with power/enter button not working so I did a battery pull to reboot the phone. It powered on and immediately went in cwm recovery restoring data.. :( .. ended up in cwm recovery menu.. still unable to select anything, so i chose reboot system. Phone booted back up and is running cm7 with original kernel. Very odd restore but it worked in the end.. just thought I would share my experience!

[AT&T Samsung Galaxy S II SGH-I777] Rockliveson123:
BLN

Anyone know how to get BLN working on this kernel. Says it is enabled in BLN Pro app but nothing works. Im thinking it is a liblights file, because in the filesystem it shows a i9100 lib lights file instead of i777. Anyone have this file? Or is there something i am missing? Thank you
[AT&T Samsung Galaxy S II SGH-I777] melbourne408:
For anyone on CM7 wanting to flash, it will boot. Make a nandroid before, sd won't mount had to wipe system cache and data, reinstall latest build from internal sd-which I did have access to in recovery- rebooted recovery and only then could I go back to my nandroid.

[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
I tried checking out Siyah 2.3.

Something in the init scripts forces USB debugging to be disabled when it boots.

Either Samsung update3 or Siyah adds some patches to cpuidle that include a massive quantity of debugging spam related to entering and exiting AFTR deep idle state.

Filesystem I/O seems to be significantly faster in benchmarks - I need to find out whether this was due to patches or tweak scripts and whether these tweaks compromise "real world" usage scenarios.

I am not seeing the high RAM benchmarks others are seeing. Basically, the only thing I see change significantly in Antutu is filesystem write performance.
[AT&T Samsung Galaxy S II SGH-I777] PuffinNugz:
not sure if this was your problem, but i was confused as well about flashing from sd card. i thought it was an error and couldn't read it, but you need to select install from internal sd instead of the usual install from sd. i had issues with it after awhile, so i'm back on entropy's.
[AT&T Samsung Galaxy S II SGH-I777] Nicktuso:
Just sayin...
[AT&T Samsung Galaxy S II SGH-I777] TechSilver13:
I got the exact same score with miui. Pretty amazing!
[AT&T Samsung Galaxy S II SGH-I777] kevtn8:
Thanks for the report Entropy512. Keep us updated about any pertinent stuff you find with Siyah. If I haven't already told you, your 11/23/11 DD was rock solid in real world usage in terms of performance and battery and it was a perfect compliment with Unnamed for battery performance. I'm eagerly waiting for you to finish updating your kernel to the latest sources and may switch back to it for my DD kernel. Also you should consider enabling the pfsync code in future updates (or releasing 2 versions of DD) as phone stability and integrity is much more important than a gain of 200-400 in quadrant. The Exynos/Mali combo is more than powerful enough for even the most diehard power users and does not need any risky tweaks to compromise integrity of data. I'm all for doing whatever to boost performance but never at the sacrifice of overall stability/data. If Gokhanmoral engaged in any risky tweaks in the Siyah kernel, please let us know asap. I will continue to use the Siyah kernel for now as its been performing well on my phone with no major problems but I'm definitely eagerly waiting for your completely repatched DD :-)
[AT&T Samsung Galaxy S II SGH-I777] kevtn8:
Awesome numbers Nicktuso. Everytime I see those high numbers, I feel very proud of this phone :-) I'm assuming that was on performance governor? Also are you on Miui rom? Any tweaks to the GPU or I/O scheduler?
[AT&T Samsung Galaxy S II SGH-I777] Nicktuso:
It was def on performance and yes on MIUI rom, just updated it few hours ago to the newest. No tweaks to anything just set the speed to 1600 and set it on performance.
[AT&T Samsung Galaxy S II SGH-I777] kevtn8:
Ic, how's the battery life and stability of Miui compared to Unnamed? I've heard that there is quite a few broken stuff in Miui....any truth to this based on your experience?
[AT&T Samsung Galaxy S II SGH-I777] Nicktuso:
Based on my experience(and you can check the MIUI thread for my posts lol), I have only had the "air plane mode/lost signal thing" literally only once. I have been using MIUI since the end of October, it's been my daily for that long. I've tried almost every single other rom, I always leave the newest MIUI on my phone and always come back to it.

To comment on the "broken stuffs", I can't honestly say I've had broken stuff. Like I've said before probably 90% of the people who have problems are just doing something wrong. I don't have a computer background or know nearly anything about coding for this stuff...but I seem to do it right every time.

Battery life is pretty good, I have chargers everywhere and a spare 2000mah battery usually always with me. I've never honestly cared about battery life.
[AT&T Samsung Galaxy S II SGH-I777] trialsrider1:
I've ran miui for close to a year now on a 3 different devices, I can say it's come a long way. The weekly releases are betas but most easily good enough to be daily drivers. They do sometimes release ones with little bugs, but nothing is technically "broken". The no signal bug is usually caused by a messed up imei, but if you have efs backup, it's easily fixed, or just reflashing the modem.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
pfsync code? If you mean the per-file sync disable - The default behavior is "stock" - if an application commands a file sync, it'll happen. I ALWAYS default to the "safe" option in the case of features I believe to be potentially dangerous. (e.g. I default to stock voltages, stock clocks, and per-file sync "not disabled", which is normal behavior.)

I have found a few performance tweaks that are beneficial in the initscripts, I won't be integrating them directly but I think the I777 community is due for a reference thread with useful init scripts of varying aggressiveness (e.g. "safe", "maybe dangerous", and "highly dangerous but with high payoff"). I'll probably work on that tomorrow.
[AT&T Samsung Galaxy S II SGH-I777] EnemyOfGlaDOS:
thanks for the info! :)

Running it on unnamed 1.3.1 and I have excellent performance! The kernel has been exceptional! Phone feels snappier. I found no boot loops, no 'dangerous' nothings. I have had great battery life with it also. I'm running v2.3.

It gives consistently superior benchmarks over entropy's kernel as well. I'm impressed.
[AT&T Samsung Galaxy S II SGH-I777] oic0:
Lowered my scores in AnTuTu :( not by much. MIUI with ICS framework, got 6700 with its stock kernel, only 6200 with this one. Guess it works better with some roms than others.

Under about phone what kernel version should it read? 2.6.35.14?
[AT&T Samsung Galaxy S II SGH-I777] kevtn8:
With benchmark apps such as Quadrant and Antutu, scores are not too consistent with just one run. I usually do around 10 runs (after clearing active apps , not ram) and avg out the 3 or 4 highest scores. This is regardless of the kernel i'm using.

Thanks for the clarification Entropy512. I was going over your change log for the 12/1/11 release and I misunderstood what was actually default and vice versa. Do you have a rough estimate of when your kernel will be fully updated to the latest sources from Samsung?
[AT&T Samsung Galaxy S II SGH-I777] Coak5:
I don't know what it was with this kernel but it would not connect via USB to my computer, when trying to reflash Entropy's DD, CWM would freeze and phone reboot, it was a total mess. I ended up having to odin the stock rooted kernel for i777 in order to get the phone back into working order and then reflash Entropy's DD. Read through all the messages and found no answers :/
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
No clue - My next release (probably tonight) will be closer.

The last thing is going to be the Samsung-specific stuff in arch/arm - that will need a LOT of rework because the overclock code must be almost completely rewritten.

I have been using Siyah Kernel from the day it online. I have had excellent battery life on this kernel. OC is at 1.6 on conservative governor. I am currently running UnNamed 1.3.1.

I did experience a weird bug. On the third day of usage, none of my computers would detect my phone. I have appropriate drivers installed so that is not the issue. Once I flashed kernel back to Entropy's Daily Driver, my computers were able to detect it.

I do not know if this problem was caused by flashing Siyah kernel or not. I will attempt to flash Siyah kernel on UnNamed again to see if it happens again.

Edit (2011/6/2011 23:32): I have had Siyah kernel on UnNamed 1.3.1 and the USB detection problem persists. I will have to flash Entropy's daily driver kernel.

SiyahKernel v2.4 Posted on December 6, 2011

Changelog:

Disabled arm topology and sched_mc

decreased the sensitivity (not too much) because of a non-scientific feeling that lowering it too much causes random jumps to 500MHz.

some platform-dependent merges with galaxy note sources

some stability fixes (at least it did not crash on my phone for the last two days)

BFQv3 & it is set as default I/O Scheduler

fixed NTFS auto-mounting

default governor is set to conservative@100-1200MHz

I have MIUI 1.11.9

(I used Entropy kernel though at first to get rid of my Yellow !) So which entropy kernel is compatible with my phone?

This might explain why my phone went into bootloop when I tried going from Siyah + MIUI to Entropy's unbrick kernel w/ root? yes/no?
[AT&T Samsung Galaxy S II SGH-I777] Tiplite2004:
Sorry thought u where on a stock base rom. If you still have the miui zip on your sdcard card just boot into cwm recovery, wipe data/cache, navagate to install zip then navagate to Internal SDcard and all of your zip should be there. Install and reboot and you have miui kernel instead of siyah.
[AT&T Samsung Galaxy S II SGH-I777] Edgarhighman:
oops. i followed the method you posted prior using this kernel: http://galaxys2root.com/galaxy-s2-o...tt-galaxy-s2-to-1-6ghz-sgh-i7774400-quadrant/

and my phone got stuck in the boot animation. But now in CWM it did bring my CWM from 5.0.2.7 to 5.0.2.3 so it did something. Am I doing wipe data/factory reset AND wipe cache partition? What is wipe dalvik cache?

I don't have a 2nd SD Card in my phone, just the phones internal memory, and in 5.0.2.7 its listed under Internal SD Card in CWM, in 5.0.2.3 its under SDCard. Tricky. Internal gives "E:Can't mount /emmc/" on 5.0.2.3

edit: I did wipe data/factory reset, and wipe cache, and wipe dalvik cache. Then installed the kernel.zip from sdcard. stuck in bootloop (single unending animation?) upon reboot.

When I delete a backup in CWM it causes my phone to reboot. that normal? I have my 1st backup when I installed root+CWM, and I have one made today, and one 5 days after my first one. Does it use different baseband and kernel in each restore (whatever you had during backup?)
[AT&T Samsung Galaxy S II SGH-I777] Hunt3r.j2:
Christ, this sounds like you've gotten yourself into quite a mess.

Okay. Get into CWM. Do a factory reset. Put a ROM like Unnamed onto the internal SD, install it, and then boot it up to make sure that you've fixed the issue. Flash MIUI again if you want after another factory reset.

Whats a good kernel that all or most the ROM's run on? Whats pretty? :) I figured deodexed/debloated/rooted/with CWM makes for good use.

If I do a "restore" is it bringing back the kernel/baseband used in that restore?

Like: Can I change the kernel, then restore my stuff using CWM's restore (from a backup)

I'd like to just come here and adb push it over to my phone... but without adb working i gotta d/l the rom from my phone lol. 280mb.

Edit: oh wow. I just tried it out, (not yet what you said, but... did an older restore and its using a different kernel! no idea what though: 2.6.35.7-gae44ffdantinm@wolverine #1)
