Thanks lofreq, that's a great guide. So as I understand flashing the modem is just like changing the drivers for something on a pc? And doesn't change anything in the rest of the android os, and if I change rom it will completely be replaced? Right? I've still got a lot of reading to do before going on to any of this as you can tell :P


Not exactly - there's essentially 4 parts to what you see on the phone, and there are dependencies between them (to some extent):

Kernel: This is the heart of the Android O/S, and is the layer that sits between the hardware (CPU, screen, RAM etc) and the applications.  It's responsible for managing resources so that apps always have enough to run correctly.  This is why optimizing it the way Devs like Supercurio & Harcore do is so crucial to the speed of custom ROMs.

Base ROM (aka PDA): This is the Galaxy S-flavoured Android O/S effectively containing all the Galaxy S drivers, but unlike closed-system devs like Microsoft, it's compiled from Source Code that has been 'released' by Samsung.  Because Doc gets the source code, he can do as he likes with it, so removes extraneous bits n pieces, optimizes it carefully, and adds other things like BLN notification etc before compiling it.

Modem (aka Phone):  This is the piece of software that actually makes your phone a phone, so it controls voice functionality, as well as sms, mms, wi-fi, 3G, GPS etc.

CSC (Country Specific Code): This is a tiny bit of code that sets your APN settings to those of your local carrier, and also influences which apps you can see in the Market.  There is some debate over whether it's actually necessary - not having an NZ CSC certainly doesn't seem to cause anyone any issues here in NZ.

Hope that helps - I was confused as hell when I started out, but you'll get the hang of it.  You'll probably stuff a few things up along the way, but there's plenty of help to be found here!!


Nicely put!

Damager:

Youll see us refer to having a JPY based ROM.. or JPX based which mine is based... For example.. last time i looked Neets was JPY based... I could have a JPY based rom as well. but she may have different kernel eg with overclock and undervolt and universal lagfix.. where as mine may have a non overclock kernel but with a voodoo lagfix.. so there are various combinations, if it works great.. enjoy, if something goes wrong, ok.. may have to change over clock.. the voltage settings, change the kernel.. change the modem! The life of a flasher!.. Most roms are 'all in one" but you still have the option to change modem and or kernel at your discretion :-)



 


Ahhh, being made an example of!

I've just cooked from the Beta kitchen (again).  Yep, life of a flasher.  I feel like Damager undressed me somewhat in his example ;-)

Thanks for volunteering Tongue out 

Well Neets, if we don't get intimate with the detail, how is anyone else to learn?  Laughing

@Neets - aww shucks. . . . I'm pretty much just regurgitating what I learned from you!! Wink


The trick, as always, is to find a combination of kernel and ROM/modem that gives you speed, balanced with battery life.  To be honest, I'm not sure we're going to see another quantum shift in performance again with the current 2.2.1 release, which is why the kernel devs seem to be fiddling with things like light recognition etc.

Even if (when) Gingerbread gets released for the SGS, I'm not sure performance will leap ahead.  I think Doc's approach of customization & refinement is the future, rather than raw speed.

But for now I'm quite happy that, with Doc's ROM, I own the best smartphone on the planet.

Just got this reply from Telecom re an ETA for 2.2 for the Galaxy S...

"Telecom/XT are not withholding this upgrade as this Samsung Galaxy S to Android 2.2 firmware update that you are talking about is at the moment not the full version ,This is believed to be the beta version.
once Samsung releases the full version then telecom can role out the updates for the Samsung Galaxy S from 2.1 to 2.2.


Thanks

Speaking of which.  Just finished flashing said beta rom.  Still going with Trasig's kernel.  And *still* the extra app I selected wont copy during the flash.

Now to put back the Generation X theme.  Must see if he's updated from version 1.14.  Might be something new!

For those of you flashing Doc roms, when you see the orange-ish bar move along (progress) when you get to about 4/5ths of the way, does the bar lose a pixel top and bottom (makes it look a bit like a sausage link)?  I'm trying to work out if I've got a problem or it's what others are experiencing.  I've had it for a couple of weeks I guess.  Cheers.

I experience a similar unusual phenomenom during a rom flash. when flashing serendipity (my preferred rom) it gets to only 50% before it says copying done.. and i always think.. oh did it actually flash/copy properly?! regardless of how many times i flash.. that always my heart skip a beat ! phew.. always works out fine though.

It finishes flashing the rom, the progress bar goes to the end, it's just at that point there's a missing pixel at the top and the bottom of the bar.

I thought if I was missing pixels it would affect my wallpaper and everything that appeared at that point on the screen but I've only noticed it during the flashing of a rom.

Unlike Michael's experience with misspelled words, this reply has nice grammatical errors.  And a lower case "t" for Telecom.  Tee hee.

But yeah, they seem to be light years behind the rest of the world.  2.2 - pffft, so yesterday!

Hey, just out of interest, do you have the snazzy black phone dialer as shown in the Gen X screenshots on the XDA post?

I just realized mine is still the garish green/orange buttoned one?

Thanks for everyones replies, so if I flash the JP2 which seems to have once been the official Telecom 2.2 update, and then the faster modem as lofreq mentioned it would be agood start from 2.1? Obviously a nandroid backup willl be done. Im still uneasy on modding my phone as I cant really afford to "break" it, but thats my problem

Yes, it's the black one.  It's a very flat look.  Because there's nothing separating the buttons it doesn't look like a number pad.  Just a black screen with numbers on it.

The uneasiness is perfectly understandable.  When I first got the phone I almost begged someone from Christchurch to help me root it.  I couldn't for the life of me even manage to get to the recovery screen.

Turned out I had one of the phones missing the 3BR - and it was only just being discovered by the community.

For all that, It's pretty hard to really stuff your phone up.  But always comforting to have someone close by whose been there, done that, could look and see that you're on the right track and what you're doing has worked successfully for others.

If you're in Chch I don't mind helping you out.  Or if you want to post screen shots here, I know there's a multitude of people who would be willing to provide the reassurance to you.
