Battery life on .13 was fantastic for me but when I tried to tether my ipad2 to my SG2 via wifi hotspot it would connect but the iPad2 would not get on the internet.

.12 battery was excellent as well but of course had the error trying to setup tether.

Just installed .14 and unfortunately as mentioned before it gives the tether error as well. LOVE the touch recovery though! That's sweet!

I checked the phone details i remember to saw a word Froyo, so i knew it was on froyo, never used froyo before or GB, i couldnt tell the difference....the version was 2.3.X something cant remember and it check because it cant boot....is this serious!??:(

I think it cant go to stock recovery too, if i press vol+, vl- and power it boot to Samsang logo and off and again and when release it stuck on the logo....what im i doing wrong? :eek:

Re: [KERNEL][ExTweaks] SiyahKernel v2.6.14 | "One kernel to rule them all" | 3/19/12

Before you start flashing anything I would advise you to read all the stickies and informational threads here. The last thing I want is to see someone brick their device. It's a lot of information, but you should take the time to read it. As I said, our device never ran on Froyo.
[AT&T Samsung Galaxy S II SGH-I777] VanillaCracker:
"Can be flashed on Samsung ROMs and AOSP Based ROMS. Currently all Samsung 2.3.4, 2.3.5, 2.3.6, 2.3.7 based ROMS, CM7 and MIUI ROMS are supported. Based on linux kernel 2.6.35.14 + drivers from Samsung sources"

This kernel should work on stock Gingerbread. 2.3.X, as you said, should be gingerbread. 2.3.4 is what our phone officially released with. If you can't get into clockwork recovery mode (Vol Up, and Down, plus power), then you will have to try putting it in download mode (Vol UP, plus power - while plugged into Computer via USB). From there, try reflashing this kernel, or any rooted stock kernel, or original stock kernel again (if you want to give up). If you flashed the kernel using odin CORRECTLY, then you should be able to get into ClockWork Recovery Mode, and from there you'd want to clear cache. Should reboot fine after that. If it doesn't clear data too and then it'll definitely work.
[AT&T Samsung Galaxy S II SGH-I777] deom2i:
I did read thread regarding flashing CWM and many pointed out to flash custom kernel that why i did install this kernel.

The phone was rooted before. I dont know who rooted the phone but the person did not flash CWM, my intention was not to root but to have custom recovery so i flashed this kernel and stuck, that all i did.

Thanks mate,

when i try CWR, the samsung logo goes off and on looping and no recovery.

Download mode works, i tried reflashing this kernel with odin v1.85 and also v 3.04 but with no luck, all flashing are successful without error. :crying:

Still same boot stuck.

Can you please provide me with rooted stock kernel link:o

Re: [KERNEL][ExTweaks] SiyahKernel v2.6.14 | "One kernel to rule them all" | 3/19/12

Are you holding the buttons in long enough? Pretty much every person who says they can't get into recovery only holds the buttons for a short while. Hold volume up, down and power in until you get the recovery screen. Don't let go until you see it. Don't let go on a reboot of the Samsung logo.

I tried holding recovery for 5 mins but the samsung Logo keeps looping on and off.

In that case here is a screenshot of that result.
[AT&T Samsung Galaxy S II SGH-I777] Nicktuso:
From the feel of things, I would say siyah's feels faster, but I never had a complaint with MIUI. I don't use bluetooth ever, but I use everything else and haven't had a problem yet, I can connect via usb to computer easily too. Honestly I'm a heavy user and use MIUI daily for the last few weeks. Love it. Now using this kernal for a solid day, haven't had any issues yet.

This is using the newest siyah kernal, setcpu is 1.6 on performance.

Same settings using whatever came with MIUI.
[AT&T Samsung Galaxy S II SGH-I777] Alucardis666:
Great numbers!
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Looks like the largest delta there is SD card writes - that seems to be where the big performance benefit is between those two. Were those both against the internal SD?

Likely either this:

https://github.com/Entropy512/linux_kernel_sgh-i777/commit/8aa5e87f89fd375f72f33e9b3c71e4b1f6b41e9d (Seems like AT&T devices have the SD speed capped for stability reasons...)

or:

https://github.com/Entropy512/linux_kernel_sgh-i777/commit/e68c203db4bc02df33c9c0c9d6d7d0548ae3d671 (bunch of ext4-related updates)

Those are next on my list, not for the next release but the one after. (This one is sound + a few other small things.)
[AT&T Samsung Galaxy S II SGH-I777] Nicktuso:
Yes internal SD card, I don't use an external one.

siyah @1200.
[AT&T Samsung Galaxy S II SGH-I777] kevtn8:
Wow Nicktuso, that number is great! What rom are you using and what governor is that on? I have not reached that number on Antutu using Siyah at 1.2 on conservative. I'm running Unnamed 1.3.1
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
One should always benchmark on Performance.

On my last run, RAM was around 150-180 points lower, CPU Integer was slightly lower, SD card write was way lower (96), database writes were way lower (310). Everything else was similar. That one was 5849, but I've hit around 6000 on other runs.

The DB writes value of the benchmarks I've seen are almost exactly what I see with fsync disabled...
[AT&T Samsung Galaxy S II SGH-I777] cwc3:
UnNamed 1.3.1, Siyah 2.3, IScrewed Theme.

Ondemand Best of 3

Performance Best of 3
[AT&T Samsung Galaxy S II SGH-I777] Nicktuso:
Performance. I always have my phone @ 1600 on performance, I have battery cables everywhere to charge it and a spare 2000mah battery charged so I don't care so much about battery life. lol
[AT&T Samsung Galaxy S II SGH-I777] K Rich:
do you not care about the life of your cpu? there really isn't a reason to run it continuesly at 1.6....
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Good way to prematurely kill your CPU.
[AT&T Samsung Galaxy S II SGH-I777] Nicktuso:
So for best results and to not kill my cpu...I'm guessing I should not leave it on performance. But can I have it at 1600 for daily or would maybe 1400 work fine? I'm sure I won't even notice much of a difference at 1400.
[AT&T Samsung Galaxy S II SGH-I777] kevtn8:
Lol, that's crazy you are definitely a risk taker. Anyways, I've heard that Antutu scores can fluctuate depending if you use an external SD or not. I'm guessing if this is the case, the class of the card might make a diff. Since you say you don't use an external SD (I'm in same boat), that makes your score at 1.2 on Antutu even more impressive. I've tried replicating your scenario and have not come close. Is Unnamed your main rom also?
[AT&T Samsung Galaxy S II SGH-I777] Nicktuso:
MIUI. I have it set to 1400 conservative right meow, so I'm sure I'll be fine with that. Don't want to go killing my phone(cpu) that quickly, even though new phones come out so often I won't probably have this one for another year.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Leaving the peak at 1600 but using a normal governor (Performance forces the CPU speed to maximum at all times) should be fine.

That way you'll know (phone getting hot) if something is using too much CPU time.

Benchmarking using only internal SD is just a good way to keep the benchmarks "apples to apples", since we all have the same internal SD.

However... On CM7/MIUI, external and internal are sometimes swapped, so CM7/MIUI numbers could be off...

Attached are my results at 1.2:

RAM is down at 850, looks like I need to investigate some tweaks here

Database I/O changes DRASTICALLY when per-file fsync is disabled (new "use at your own risk" feature in DD 12/1 - uploading soon)

SD card write speeds are around 10 MB/sec, seems like they are much faster on Siyah. Time to patch the filesystem code up to update3.
[AT&T Samsung Galaxy S II SGH-I777] kevtn8:
That's interesting. I didn't know a rom can make such a drastic diff with affecting benchmarks. How is Miui in terms of battery life, stability, features, and smoothness when compared to Unnamed? Maybe I need to try it out myself :-)
[AT&T Samsung Galaxy S II SGH-I777] kest874:
I have a weird issue with the kernel 2.3 the power button starts faking screen captures. The phone won't wake unless I push volume up. After a reboot the power button works normally for awhile, then the issue comes up again. Any ideas?

Running latest Unnamed.
[AT&T Samsung Galaxy S II SGH-I777] kevtn8:
I had same issue , however all is fine after reboot. If that problem still persists, boot into recovery, clear dalvik cache than reboot back. After one normal reboot, that never happened to me again :-)
[AT&T Samsung Galaxy S II SGH-I777] Nicktuso:
I've been using MIUI for almost a month and I love it for a daily. Battery life isn't bad, I'm a heavy user and I get almost 24hrs out of it.

Tried this but no dice... Driving me nuts!
[AT&T Samsung Galaxy S II SGH-I777] NJGSII:

Awesome kernel. The battery life is also really good from what I can tell so far. It is similar to what I was getting on Entropy's kernel. The performance is amazing too.

Has anyone noticed their phone charging any faster than usual? I rarely watch my phone while it charges but it seems to be charging way faster than before.

Does anyone know how to get BLN working on this. I'm on miui and BLN pro sees that the kernel is compatible but nothing lights up when I get a notification

Edit**: in the kernels thread it says the liblights filled is automagically installed but it doesn't seem to be working. Do I just take the liblights file from the i9100? Thanks
[AT&T Samsung Galaxy S II SGH-I777] kevtn8:
So from your analysis of Siyah's source codes so far, have you confirmed that Gokhanmoral disabled the pfsync in his kernel? Your analysis of the scores results being linked to the pfsync is very interesting. If the pfsync is indeed disabled in Siyah's kernel, can you elaborate on the dangers or instabilities of this state?
[AT&T Samsung Galaxy S II SGH-I777] roadrash7:
Isn't it better for battery life if our phone charges slower?
[AT&T Samsung Galaxy S II SGH-I777] gr8hairy1:
Technically true. But phones charging chip have settings that can be adjusted. The chip in our phone is a bit limited. Charging in the beginning can be 'turned up' and the battery charges very well. Towards the end it's best to be a slower, lower power, charge.

Even if the chip can not be adjusted, it's setup by design to not allow too 'fast' or high of a voltage, so the phone/battery doesn't get fried.

[AT&T Samsung Galaxy S II SGH-I777] jgrimberg1979:
That would be me. Works nice doesn't it? Seems to run smoother when you run the script first. Hit thanks if you liked the link and def thank the dev
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Still not sure. The DB I/O performance is consistent with fsync disabled - but those benchmarking could have been running ROMs with the hacked sqlite that disables fsync. The thing is that SD card write is also MUCH higher for some reason - so this could be why the performance for DB I/O is much higher. Still working on identifying the source of the improved write performance. Looking less and less likely to be update3 - I've patched in the MMC/filesystem stuff with no changes.

It MIGHT be some simple init scripts tweaks to cache settings and such though - don't know yet.

If you mean "life" by "charge/discharge cycles" or "months before capacity loss" - yes. Another reason to poke at Siyah, maybe he figured out how to get the MAX8997 to take control. If he did, that's something I'm going to focus on porting immediately. (See Charginghacks in my Infuse series...)

Yup. However since our devices counts usage against the current limit, a 200 mA limit increase (less than 25%) may increase battery current by more than 25%. (e.g. total current goes up, but current that is diverted from batt says the same.)

For example, a limit of 800 mA on the Infuse was a MAJOR improvement over 600 mA in quite a few situations. If done properly, one can get most of the best of both worlds - if the charger slows down BEFORE the battery does, it can be quite good for the battery. Look at Apple's "step charging" patent covered on Engadget at some point. (This is basically what I had on Infuse.)

If we can get charging control away from the MAX8922 and back into the MAX8997, that is a BIG deal.
[AT&T Samsung Galaxy S II SGH-I777] Smith7018:

[AT&T Samsung Galaxy S II SGH-I777] Peaster111:
Well.. round two (v2.3) with this kernel. No "USB to PC" connection on the 2.2 version was a killer.

Version 2.3 seemed to work pretty well for about a day and a half, then things got squirrely. I got a couple of random reboots. When I tried to take a screenshot (home+power), the phone restarted and froze at the bootanimation screen. I let it sit for about 15min thinking maybe the cache was rebuilding for some odd reason. Nope... It stayed on the bootanimation screen. After several attempts at restarting using battery pulls. I ended up reflashing back to Entropy's.

Sure the Siyah kernel seems to have a little better "numbers" then Entropy's kernel, but the "numbers" are just interesting and don't really mean much. Stability, day-to-day performance and battery life are far more important to me. The last two are virtually the same (very close) to me. I've never had any stability issues Entropy's kernel.
