As to source... Samsung is good at playing the "sorry we didn't see your request" game.

Sometimes they are great about posting sources - the Captivate Gingerbread update had sources posted 3-4 weeks before AT&T took it live. (This was still 2-3 weeks after the firmware first appeared as a leak.)

The I777 source went live 2-3 weeks ahead of device launch.

The Infuse Gingerbread update has been live for 2-3 weeks - still no kernel source.

So who knows whether I9100 ICS source will be early or late. I'm hoping for early! :)
[Galaxy S II Original Android Development] tolis626:
Well,if they don't put sources up early,we can just start e-mailing them until their servers crash or something.At least we can get revenge for it!Muhahahahaha! :D :p

On a serious note,I don't think they want to disappoint the GS2 community.We are far too many for them to ignore.Not that manufacturers haven't ignored large communities before(peek-a-boo HTC and Motorola),but I don't think Samsung want to follow that paradigm now.

[Galaxy S II Original Android Development] rauschkugl:
Yes that is correct but you won't have root then. Autoroot was removed from the kernel. Flash cfroot for your rom first then you can install siyah with Odin or trough cwm.

[Galaxy S II Original Android Development] BrotherZero:
Apologiez for some very noobish questions since I haven't done this before and this is a very long thread and I dont want to brick anything(just heard a buddy of mine do that).

1. If I'm gonna flash with CWM, which of these files should I use?

Siyah-v2.6.12-CWM.zip

Siyah-v2.6.12-att-CWM.zip

Siyah-v2.6.12-ntt-CWM.zip

Siyah-v2.6.12-kor-CWM.zip

What's the meaning of the different prefixes?

2. If I use CWM, do I just flash it like a ROM, chosing "Install zip from SD-card" in recovery?

3. What is DarkyOTA? Is it like ROM Manager?
[Galaxy S II Original Android Development] teiglin:
1. For an international/European I9100, you want the first one. The att version is for the I777 from AT&T in the US, the ntt version is for Japanese version from NTT Docomo, and the kor version is probably for Korean phones (not 100% on that one).

2. Yup. You don't need to do a wipe or anything.

3. I've never used DarkyOTA personally but I know it has many of the same functions as ROM Manager and CWM app, such as boot to recovery, flash kernels, etc.
[Galaxy S II Original Android Development] BrotherZero:
Thanks for the fast reply!

A last question, I'm going to give BLN a try so I'm going to wipe dalvik and cache. Wiping Dalvik and cache, you don't loose any data or settings on the phone? You only lose that by wiping data/factory reset?
[Galaxy S II Original Android Development] teiglin:
Correct. Usually the first boot after wiping Dalvik will take 5-10 minutes depending on your ROM, so give it a bit. If it seems to be hung after 10+ min, you can reboot by holding down the power button or doing a battery pull, and it will usually still boot fine after that.

I've never used BLN myself but I don't think you should need to wipe dalvik in order to enable it, just flash this (or any other BLN-enabled) kernel and install BLN app from the market. Of course, as you noted there is no harm (data loss) involved in wiping dalvik, so it is a good thing to try if you get force closes after flashing something.

Has anyone tried this kernel with checkrom v6?

Im not getting a good battery performance... it was much better with checkrom v6
[Galaxy S II Original Android Development] XDA mark:
I am now doing a full day with CheckROM V6 + Siyah 2.6.7

The only problem is, I tried my standard UV settings (Geko's settings +50mV) and my phone froze after not even one minute. Looks like this ROM doesn't like UV?
[Galaxy S II Original Android Development] fatjivi:
Ive had no problems with magic config settings...no crash or freeze since yesterday...only my battery drain is a bit on the higher side compared to v4 rom

I tried both 2.6.12 and 2.6.11..pretty much same drain
[Galaxy S II Original Android Development] petexx:
Hi Guys,

Yesterday I flashed CheckROM + SiyahKernel and I have lost my root access.

Can you please advise what is the best way to regain root access?

Thanks
[Galaxy S II Original Android Development] MistahBungle:
From the first post in this thread - "If you lose root after flashing the kernel (unlikely), flash this". Or flash a CFRoot kernel.

Hi guys!

Do you mind helping me see if my UV is achieving good result? I asked this is because I do not really know how to interpret the info obtained. :(

Feel free to comment as I wanna learn. Thanks!
[Galaxy S II Original Android Development] GJ123:
Hate to say this but there is no way I know to show that in numbers, UV is mostly theoretical I believe.

Could somebody give me real life examples and numbers?
[Galaxy S II Original Android Development] Entropy512:
UV will gain you, at best, 3-5% ONLY on core power typically. I've never seen anyone drop voltages enough to remain stable to get more than that. It also won't get reflected in any battery usage estimates. When the device is sitting idle, it contains almost no benefit since core power is a small fraction of the power budget. At 1.2 GHz full load it'll save you 3-5%.
[Galaxy S II Original Android Development] veyka:
Looks fine, check your partial wakelocks, measuring how much you are saving by UV'ing would mean running repeatable tests, preferably automated with and without the UV.

If you are happy with your battery life, be happy, and don't worry, but UV isnt a magic bullet, you are talking a % UV so at best you will gain that % battery life, but consumption is not really liner with voltage so, and also as noted by Entropy512 above, cpu voltage is only a tiny part of the equation.
[Galaxy S II Original Android Development] BrotherZero:
Does anybody know if this is using a newer bootloader, so you can't use a usb jig to remove the yellow triangle?
[Galaxy S II Original Android Development] Entropy512:
Kernels and bootloaders have NOTHING WHATSOEVER to do with each other. (Well, nearly nothing - absolutely nothing in the case of Gingerbread for the I9100, ICS might change things.)
[Galaxy S II Original Android Development] alcurtis93:
All of the guys comment above and no :)
[Galaxy S II Original Android Development] veyka:
Also nothing should touch your bootloaders without telling you beforehand, and no rom should include them, same with modems.

There is 0 reasons for kernels to touch the bootloaders as well.
[Galaxy S II Original Android Development] BrotherZero:
Well, then I learned something new today. =)

Wait, now I'm confused. So a bootloader is always flashed separately?

Cause on another forum I was on there was a guy who bricked his phone when he flashed a bootloader and then he was told that was a risk when you flashed the bootloader separately and you should always flash a complete firmware(like KF3)???
[Galaxy S II Original Android Development] veyka:
There is always a risk when you are updating the bootloaders, but flashing them on there own is not any more risky than flashing a whole rom.

Just make sure you have a good USB cable and that your computer isn't going to crash ;)
[Galaxy S II Original Android Development] Entropy512:
In general, one should avoid touching them unless you REALLY have a good reason to do so (such as a clearly documented known incompatibility - On the original GalaxyS, bootloaders were required when going from Froyo to Gingerbread.)

On the original GalaxyS, VERY BAD things (as in hardbricks) happened if the primary and secondary bootloader didn't match.

Basically, right now, the only thing that touching a bootloader can do on the I9100 is hardbrick you - it never contains any benefits. This may change with ICS.

If you misflash a kernel, you can always recover by flashing a good one in Odin. Same for flashing firmware to /system

If you misflash a bootloader, there is a good chance you will hardbrick in a way that can't be recovered without a JTAG box.
[Galaxy S II Original Android Development] BrotherZero:
Oh man, you guys are freaking me out about touching the boot loader now. My only reason was to get rid of the yellow triangle that keeps bugging me every time I start the phone. :D

Let me see if I got this right. I can't get rid of the yellow triangle cause my bootloader is too new for the USB-jig. I should stay away from flashing the bootloader, but I'm safe(r) if I flash a complete firmware like KF3 which according to another forum contains an older bootloader?

1. I could make a nandroid.

2. Flash KF3 and get a new bootloader(cause flashing a complete firmware is safer according another forum).

3. Use my nandroidbackup(and then I will keep the old bootloader from KF3).

4. Use the jig?

Would that be a safer way to do it or does it not change anything?

I know, it's pretty lot of effort to just get rid of a yellow triangle, but it's almost bugging me even more now when I know can't get rid of it...

And sorry for the OT.
[Galaxy S II Original Android Development] teiglin:
I suppose newer bootloaders could have changed this, but you should be able to remove the yellow triangle by flashing a stock kernel, then using CWM app or similar to flash back to a kernel with CWM recovery. You just have to make sure to extract and flash the zImage directly after booting on stock kernel. Short instructions:

1. extract zImage from siyah zip (or any other cwm recovery kernel), save it on your phone somewhere

2. make sure you have cwm app installed (don't think this comes with siyah?)

3. flash a stock kernel (using odin or whatever, don't think it matters how)

4. in cwm app, select flash kernel and choose the zImage you saved earlier

5. reboot, yellow triangle should still be gone as long as you don't flash anything else using odin

Chainfire has slightly more complete instructions in his cf-root thread but that's the basics and you sound like you know what you're doing more or less. Unless you expect to be returning the phone or sending it in for service, it seems needlessly dangerous to mess with the bootloaders.
[Galaxy S II Original Android Development] veyka:
Just flash the old bootloaders via odin, as per this thread, once you have the old bootloaders as long as you dont flash a official rom with the new ones in you will be fine.

Nanadroid wont touch your bootloaders/modem so you can nandroid around as much as you like.
[Galaxy S II Original Android Development] BrotherZero:
I'm not sure I got all of that since it's really late, but it looks like a good method, if I don't have to touch the bootloader. I'll give it a better look tomorrow. Thanks!

Yep, that was kind of my idea with using the nandroid to go back where I started, but without changing back the boot loader.

Although I'm a bit perplexed about what you said about that only problems I could come across was if I flashed a new official ROM that had a newer bootloader.

Cause if I had an older bootloader to begin with when I bought the phone, and was going to upgrade my firmware, wouldn't I be doing just that, flashing a firmware with newer boot loaders?
[Galaxy S II Original Android Development] tolis626:
If you are so desperate to get rid of the yellow triangle,you can try Chainfire's TriangleAway app.It works with all current bootloaders(even those who prevent the jig from resetting thr counter),so you won't have to mess with flashing bootloaders.You just have to use an ICS build

Then you can just Nandroid back to your rom.

[Galaxy S II Original Android Development] pikachu01:
Do you OC your GPU? Try undervolting your GPU using Voltage Control.

Also, some games are badly coded to make use of high CPU/GPU frequencies even when it doesn't need it. Try other games to make sure.
[Galaxy S II Original Android Development] Entropy512:
If you're careful, you can flash newer firmware WITHOUT flashing the bootloaders.

It sounds like in your case, you want to:

Flash back to original/older bootloaders (be careful with this) - If you already have newer bootloaders by accident, this is one of the cases where touching bootloaders is justified

When you return to newer firmware, be more careful about flashing bootloaders. If it's a stock image like Intratech's downloads, remove boot.bin and Sbl.bin from the tarballs before flashing. If it's a custom firmware flashed in CWM, check for boot.bin and Sbl.bin first and don't flash it if it has these - but it's EXTREMELY rare for CWM-flashable firmwares to contain BLs.
[Galaxy S II Original Android Development] sianzb0i:
If i want to tweak the voltages, should i use tegrak overclocking app or the voltage section in setCPU?

I would recommend voltage control from the market. But from those two, go with set CPU.

[Galaxy S II Original Android Development] sianzb0i:
Hi bros, I am asking cos when i change voltages values in tegrak, the vaules in tegrak changed but i do not think it changed the voltages in the system. whereas, if i changed for example 100 mhz to 900mV in setCPU, it would freeze in awhile. tegrak UV/OC will only work then i reboot the phone.

I will try voltage control tonight.

---------- Post added at 10:29 AM ---------- Previous post was at 09:58 AM ----------

how do i change or select an I/O scheduler? or it is tied to a governor?
[Galaxy S II Original Android Development] teiglin:
The two are not tied together. I've never used tegrak's app, but in voltage control there is a separate dropdown for cpu governor and i/o scheduler on the General tab (the first one when you start the app).

[Galaxy S II Original Android Development] 3c:
Have you tried System Tuner? Works like a charm for both UV/OC on Siyah kernel and many others.

Note the IO scheduler is not tied to a governor, but relate to IO scheduling (:D) for block devices. It's often use for Sd card and system partitions.
[Galaxy S II Original Android Development] MistahBungle:
Hey Cedric. Nice to see you on here ;)

Yes, ST is fantastic for under/overclocking & changing voltages on Siyah. Have been using it since the first few days I've had my phone & never needed anything else for this stuff (and a whole heap of other functions).

I definitely recommend this app :)

[Galaxy S II Original Android Development] MistahBungle:
Try letting your phone run for a few hrs off charger & then have a look. No reference (from memory, been a few mths since I've used BBS a lot) means there aren't any wakelocks for the reference you're using (since charged, since unplugged, custom ref). I'm sure someone will correct me if this isn't the case :)

Also, BBS tends to throw up some weird results/not work well sometimes with Miui in particular (also if my memory serves me correctly).

hi, im having very huge battery drain on DXKL3 ROM and siyah kernel.

I came back home, which is 12 hours later, and phone was in standby mode all day and batt drain was 5%.

and now after 3 hours of usage it is at 70%.

CPU has already been undervolted.

This amount of drain is considered quite huge as compared to when i was using KH3 modem and ROM and CF rooted kernel

can someone advice?

Install betterbatterystats, check for wakelocks, take screenshots, dump to file, post them here.

As far as using 30% in 3h, that would end up being 10h screen on time, which would be very good, if you mean in 3h of screen on time you lost 30% battery.

On topic tho, I've gone back to 2.6.7. I've found 2.6.12 to be slightly better at deep sleep while in idle (say 99% Vs 98%), but it does use around 15% more battery during moderate/heavy use compared to 2.6.7. I didn't use 2.6.8/9/10 & found 2.6.11 a little bit better with battery drain compared to 2.6.12 but not a patch on 2.6.7. Just my observations and obviously YMWV.
