VtechTaka: I have had very mixed results mixing and matching basebands with kernels it seems to me  there is some correlation between the 2 in regards to radio stability ,you may be able to interchange from a compatibilty level but it doesnt always translate into a well matched symmetry from my experience at least.

I can say with absolute certainty that there's no tie between a kernel and a baseband.

Samsung have released 4 sets of source code for the GT-I9100. There was an original release and 3 updates. Almost all of the custom kernels available are built from one of these 4 sets of source code. A small number might be built from the CyanogenMod source code, but these are fairly rare in comparison.

There are no such sources for baseband packages. The only basebands available are the ones from Samsung. (This is true even with CyanogenMod, as they use the Samsung basebands with their code.) Samsung have released a large number of basebands, as they keep tweaking things to try and get a good mix of signal strength and battery life. They're also customised for certain carriers, such as Vodafone or Telecom.

So, given that there are only 4 major firmware sources (main release + 3 updates), and dozens of basebands, there is no possible way that a baseband has any tie in to a kernel.

Also, I've been following custom kernels for around 8 months or so, and have never seen any mention of a kernel dev writing specific code to target a specific baseband. If there was any matching between baseband and kernel, the devs would comment on it so that people would use the right baseband.

Edwood: I have been searching for a couple of days, and not finding. I am looking for a changelog or 'highlights' or any information at all about the firmware update I just performed using KIES.

Strangely, Samsung never release any changelogs for their firmware updates. They simply make new firmware available and expect that people will update.

The only good news is that they go through a fairly extensive testing process, especially for carrier-branded variants, so any update is going to be an "upgrade" of some sort.

For example, you might find that the VFNZ update will contain a newer version of the base Android 2.3.x OS. There is a known set of changes that are included in each of these versions.

Hmmm... ok, thanks nzgeek... much appreciated.

So according to this wealth of information, I've just added "several improvements and API fixes".

If anyone stumbles across any informal details on what these 'improvements' might be, share the love.


Chur.

Edwood: Changelog for firmware update:

Hey folks,

I have been searching for a couple of days, and not finding. I am looking for a changelog or 'highlights' or any information at all about the firmware update I just performed using KIES.
It seems most people just blindly update the firmware... Personally I prefer to know what a firmware change is doing, preferably before I flash. However, I gave up looking and just updated last night.

My phone is about a year or so old, i'm running the stock ROM, and purchased it from VFNZ... I wasn't smart enough to write down my versions before i updated.

I am now running:
Android: 2.3.3
Kernel: 2.6.35.70I900XWKG3-CL374944
Build: Gingerbread.XWKG3


How on Gods green earth am I supposed to find a list of changes associated with this firmware!?

Anyone?



2.3.3 includes WebM support, better NFC support, improved Bluetooth compatibility,  minor graphics improvements, better interface for voice search resluts.

You can view a more technical changelog over here: http://developer.android.com/sdk/android-2.3.3.html

A complete version history can be found here: http://en.wikipedia.org/wiki/Android_version_history

On that note, it's odd that you only just updated to 2.3.3 when the Icecream Sandwich update is just around the corner...

@ nzgeek Thank you 'you make some very valid points regarding devs instructions.Hadnt really delved into kernels ,but it was more the experiences after flashing bases and kernels.
Makes perfect sense now i look at it.

It's all too easy to misunderstand how the internals of Android work. I'm only aware because I'm a developer by trade, and have taught myself to figure out the internal workings of software. For most others it's some sort of deep dark voodoo Smile.

It still is possible that you may have seen some changes in data performance (signal strength or transfer speed) with given baseband/kernel combos. There just wasn't any real link between the two. For example, one kernel might contain some code changes or optimisations that allows it to have a better data throughput. It might have been paired with a baseband that had a higher signal strength, but worse battery life. Each of these effects is separate and independent, but they work together to produce a better overall effect.

I run CheckROM v6 (Awesome) and each time I plugin to my desktop cradle I get a prompt that USB Mode disables Bluetooth which I am ok with, but I want to have it automatically reenable BT when I unplug from the cradle, anyone "have an app for that"

Cheers

It was suggested I re-post this here:-

So yesterday I noticed my relatively XT branded SGS2 getting very warm especially up round the top near the camera area.  I had downloaded nothing unusual, not strange apps running, it was just sitting there while I was driving (was connected to hands free).  Using task manager I made sure all Active applications were closed and cleared the ram . . . . after a while the phone cooled down.  I had had a problem with the youtube app not responding earlier and wondered if that may have been an issue.  Anyway decided to completely reset phone and then updated any google app.  Fully charged phone. 

Today I noticed it was warm/hot again and but could see no reason and then a while later I received a low battery warning and within 5 hours of virtually no use I was down to 15%  The thing that stood out in Battery usage was Voice Command at about 18% but I dont use it and didn't start it, the others were Display, Android Svces and Android sys (from memory) all around 20%. 

The phone has now been reset and I am recharging, and I wondered if anyone had any ideas or maybe there is an update I should not download that might be at issue?

Get better battery stats app and check for wake locks. I am guessing google maps even if you don't use it (I had this issue and reverted to 5.8 and now can easily get 2 days from a single charge with moderate use.

Has anyone encoutered WiFi/BlueTooth concurrent operation issues with S2? I have BT stereo headset, when I use with WiFi active it drops out after 10 to 20 minutes, with WiFi off they remain connected all day.

Note: OoTB XT S2.

I suspect it's my 2.4GHz saturated environment that is pushing it to the limit. Do you use BT streaming or "on event", I.e. When a call comes in?

Anyone else having issues if they click the notification link for geekzone threads on new emails, and it will display just the summary of the pages and no thread content, and then just the reply dialog box?

I am using chrome.

Cheers
