[Galaxy S I9000 Q&A, Help & Troubleshooting] namzad:
Okay, Long story here folks.

Firstly, I'll just let you know that I'm from Saskatoon, Sask. Canada. And my carrier is Sasktel.

About a month ago i decided to try using a custom Rom. I decided on, and successfully installed Darky's V10.0 RC5.

Initially I was thrilled! It was fast, stable, and improved my battery life by about double.

However, When I traveled outside of Saskatoon, I had no phone service. It was only when I passed through major cities that I has service. After some research, I discovered that Sasktel uses 850/1900 Mhz signal. The modem that was installed with Darky's ( I think it was JVK ) did not support 850 Mhz, but did support 1900Mhz which are set up in major cities, but not along highways.

Again, after some research, I found that the JL2 modem supports the 850 Mhz. I Kept Darky's installed, downloaded the modem file from samfirmware, flashed the JL2 modem through Odin, and enabled 850Mhz via *#*#197328640#*#*

The problem is that my battery life is terrible again. I only get about half a day out of it. This is a huge testament to how much the baseband version affects battery life.

So, my question is - How many modem/baseband versions are there available? And which of these support 850Mhz? Is it recommend to mix different build versions with baseband versions?

Can someone recommend a version that has excellent battery life and supports 850?

I've scoured the internet and haven't been able to find anything.

I'd appreciate your assistance.

Thanks,

Dax

I seem to be having the same sort of issue with Bell, all these custom roms / modems work awesome in the cities, but once your on the highway you have no coverage, very frustrating.

Currently looking for ways to access the 850 band with android 2.3, currently no luck, will post if i get results. :/
[Galaxy S I9000 Q&A, Help & Troubleshooting] astralmind:
I believe kc1 is currently the best 850. however it is a froyo modem... it does work but its not.perfect. tubjv6 is supposed to support 850 but i havent seen it anywhere
[Galaxy S I9000 Q&A, Help & Troubleshooting] namzad:
pileot,

I've been able to get 850 working on Android 2.3. I found the answer on XDA. After you've flashed your custom rom, go to samfirmware and create an account. Then, find the i9000 firmwares for America/Australia and download the I9000UGJL2. Extract the modem file and flash it through Odin.

Then, you need to enable the 850Mhz band by following the instructions here: http://xdaforums.com/showthread.php?t=1042113

The problem for me is that i've done this, and the battery useage is awful. I'm looking for a different 850 modem that has excellent battery life. Any input is appreciated.
[Galaxy S I9000 Q&A, Help & Troubleshooting] namzad:
astralmind, I found the TUBJ6V on Samfirmware.

I'm downloading now and will let you know the results.. Thanks.

Also, i just noticed that JL2 is for Android 2.2, and i'm running 2.3.

Everything works okay, but the battery drain is pretty bad. Could this be because i'm using a Froyo modem on Gingerbread?
[Galaxy S I9000 Q&A, Help & Troubleshooting] namzad:
Found a thread that might be helpful - it's got a big list of CWM flashable modems. Apparently, they support 850. No info on which work well, or which perform well.

just downloaded the cwm3_tljl3, the tijl3 is what I used on my Telus galaxy all the time and had good battery and excellent service on Darky's 2.2 roms. Just installed on the wife's Bell Galaxy, with Darky's 10.1 and seems to be working just need to test out the service and battery life. Going out of town in a couple of days and will report back with service and battery life.

[Galaxy S I9000 Q&A, Help & Troubleshooting] snab321:
do they work on galaxy S?

cuz it is posted in captive section :confused:
[Galaxy S I9000 Q&A, Help & Troubleshooting] turbare:
They work, I'm using an UGJL2 from that page, on a Galaxy S (i9000).

Just make sure you get the CWM3 version if you have Darky, and install it from CWM recovery using "install zip from card".

And pay attention that you take an i9000 version of course, because there are 3 batches of links there, i9000 2010, i9000 2011, and I897 2011.

I used the 2011 ones since I just got my phone two weeks ago.

Thanks for the kernel.

After I flash your kernel, my titanium backup is saying that I don't have ROOT access. It say "Sorry, I could not acquire root privileges.." Pls help..

add info:

Before I flash your kernel, I was using [CF-Root v3.7] KE2/7/8 - su+bb+CWM3 from chainfire. My titanium backup apps was fine.

Does this Kernel have the yellow warning at boot?
[Galaxy S II Original Android Development] tegrak:
@eatingking

there is no lagfix for s2.. and this kernel is cwm independent. I do not know how to use it.

@KillerBee

Yellow text is not warning. What is the text??????

@Lio78

Thank you~ :)

After flashing this with ke7 Stock and im getting a yellow warning triangle on boot. Is this normal?
[Galaxy S II Original Android Development] Sebring5:
If I'm using angelom 1.7 rom with Tegrak overclock, is there any point to installing the Tegrak kernel?
[Galaxy S II Original Android Development] tegrak:
You meant that triangle? yes it's absolutely normal..

The triangle icon means you are using a custom kernel.

You can remove it by JIG. search thread~ JIG

i think only custom rom (Villain) is not working. stock should be working fine. i will test further.

****Note**** Fixed. FYI, for those who are running Villain rom with Tegrak kernel, please install VRtweaks then install symlink fix to prevent wifi issue (obtaining IP)

Bootsound

Hello Tegrak could you make a version of Lulz kernel with bootsound enabled?
[Galaxy S II Original Android Development] lowrider_05:
hey tegrak, first, great wok with your kernels and oc app but the lulz kernel build 3 breakes the HDMI out of the phone and when i go back to build 1 it works again maybe there is something you could do about it. THX
[Galaxy S II Original Android Development] pcboyy:
hey, thanks very much! i've stopped using Lulz since i got wifi issue 'Obtaining IP' .. and yes, i come from Villain Rom. And using your tip really solves the problem! much much thank you!.. now it's really worth paying for the Ultimate!
[Galaxy S II Original Android Development] MKD73:
Villian is XXKF2 what Luiz Kernel or Tegrak Kernel do you use with it as i cannot see a build for XXKF2 in the OP.
[Galaxy S II Original Android Development] nightranger73:
Zskf4 or xwke7... it doesn't matter... Samsung hasn't released sources so IMO no real big changes from latest source released ke7

The game of matching kernel versions is born with cfroot but this is because that kernel aims to give you a firmware close to stock as possible so kernel version has to match PDA but this is meaningless without changelogs when they may have only updated a lib for haptic feedback or a module... and even without proper testing as they differ only few days

Lite 1.5/Tegrak's kernel/1500Mhz
[Galaxy S II Original Android Development] redbullman:
Hi there. I don't know if anyone else experiences this, but I get much lower and more inconsistent Quadrant scores with the Lulz Kernel on KF4 rather than the original Tegrak KF1 Kernel on KF1. I used to to always average between 4000 and 4400 with Tegrak. Now on Lulz 3, I get anything from under 3000 to just over 4000.

Why the huge difference? Obviously the original Tegrak kernel had only 5 cpu steps and Lulz has 7 - does this make the difference? I've just switched over to the BFQ scheduler (Lulz 3) on Tegrak Overclock to see if any different.

Thanks
[Galaxy S II Original Android Development] tegrak:
Have you tried with "Performance" governor? If you do that, you get the same score. (I've already tested)

Quadrant doesn't use the maximum frequency in some cases.

For example, in 2D bench, it doesn't need full cpu resource. so you get lower points with additional cpu steps.
[Galaxy S II Original Android Development] tegrak:
@c010 @tonysac

LOL :D :D
[Galaxy S II Original Android Development] redbullman:
That's interesting actually. Just ran Lulz 3 under performance scaling and got almost 4600! Interesting that I have to run Lulz as performance to get the similar scores as Tegrak kf1 using on demand.

Which schedular are you recommending now? Is it deadline or bfq?

Great kernel and overclock apparently and fantastic support Tegrak.

Thanks
[Galaxy S II Original Android Development] Tricky103:
I agree. I have tried both kernels today. The lulz build 3 is very nice. I am enjoying the additional of features.
[Galaxy S II Original Android Development] nightranger73:
Having more step to ramp up and doing this only after CPU reaches a load threshold, using on demand governor it happens that on short tasks the CPU hasn't the time to jump at higher frequencies thus resulting in a little delay in task completions. But that's true only for benchmarking tasks because when there's need for true power it works.

BTW don't use quadrant. It's only a good random number generator as it give different results each run and it doesn't support dual cores.

Better choice for comparison is cf-bench or smartbench 2011 that give you almost the same results but the first IMO is better because it can't be cheated and it's trying to build a good database for platforms/roms/kernels performances.

[Galaxy S II Original Android Development] Spartoi:
Since Lulz kernel is built using the Korean (SHW-M250S) source code, wouldn't the Tegrak kernel be better for i9100 devices?
[Galaxy S II Original Android Development] tegrak:
Europe and Korean S II have almost same specification.

Differences are here.

Korean S II : NFC / DMB

Europe S II : FM Radio

So I think latest source is better. build 3 improves lcd colors, light sensor.. etc

Firts, this kernel looks awesome Tegrak.

I wanted to ask if there are many differences between the recovery you are using and CWM. Right now I'm using CF rooted kernel, and I use to install some tweaks via CWM (themes, etc). Is it possible with this kernel?

Im asking anyone who is using the kernel actually, thanks a lot.
[Galaxy S II Original Android Development] xtrememorph:
steveman29, which governor are you using?
[Galaxy S II Original Android Development] spania85:
My guess is that you can use it with villain because I saw Rodigezstyle settings in tegrak overclock thread and he is using Litening, which is based on KF2, same as villain. He was using Tegrak KF4 Build 24 Kernel. He said with awesome battery life and performance on games. You can give that a try.

About cognition I dont know since it is XWKE7 based. I'm on cognition myself but havent tried any... yet hehe.

You can use Tegrak-Kernel-Build-23-for-I9100-XWKE7.tar , see first post from tegrak. That should work with cognition. Hope that answered your questions.

You don't have to match kernel with firmware versions. It has no importance at all since they're all for 2.3.3.

The game of matching kernel version is born with cf-root as that kernel is done with the purpose of keeping your firmware as close as possible to stock but nothing is keeping you from using a kf2 kernel on a ke7 firmware.
