[Q] Flashing a I9000 Rom (Kernel question)

Hi... i've been with my Captivate for like a month now, done some reading, even tried some custom roms like cognition!
Since i live in Brasil, i would like now to try the ROM's from the Galaxy S that is sold here.
I've read somewhere that the carriers from Brasil which sells the Galaxy S have just released the Froyo version and some already have upgraded and are enjoying it.
So, based on that i would like to know:
1) Can i try their ROM's ? I ask because our Galaxy S (the one from Brasil) has Digital TV... Dunno if this could cause a issue with the kernel.
2) If so, how exactly do i do it? Do i flash a spare Kernel first, then flash the ROM?
I've been checking I9000 reoriented v2.2.1 12.10.2010 topic: http://forum.xda-developers.com/showthread.php?t=808286
but there's no information on how to proceed with installation.
Thanks

[Q] Can I get back to 2.2.? from 2.3.3?

So, I am thinking about putting custom ROM to my SGS i9000. Its currently with Android version 2.3.3.
I've been reading through this forum and most of custom ROMs are for Froyo? I mean many of instructions say that you have to be on Froyo if you want to use this ROM.
My question is must I get back to Froyo somehow or is it possible to put custom ROM for my current Android version?
Sorry about my noobishm. And I hope my english is good enough for you to understand.
Many thanks

Wrong, most of the custom roms are based on gingerbread. Stay as you are mate more excitement to come

You can always switch between 2.2. and 2.3.x. The only thing you need to pay attention to is that you need to flash the proper bootloader.
Flashing a bootloader is risky insofar as if the bootloader is not flashed properly, your device is thoroughly bricked and can only be revived by Samsung (or someone with the proper hardware). Furthermore with Froyo you may erroneously flash a locked bootloader which would make you stuck with that one ROM for the rest of your device's life, so make sure you only flash unlocked ones.
This said, there are actually few ROMs out there that still rely on Froyo (Insanity comes to my mind as an example). So you probably won't need flash Froyo just because of custom ROMs. Simply follow DonVito2020's link and choose a Gingerbread one.

Look at the fifth comment. Nice instruction, but is it safe one?
I'm gonna try it if it is.

It looks like a good how-to. Whether it is safe or not I cannot tell without looking into the files, however since the post links to Gingerbread ROMS, not Froyo ROMs, it is most certainly safe, as far as the bootloader is concerned (at least I have never heard of locked Gingerbread bootloaders for the Galaxy S).
Though since you are already on stock Gingerbread, take a look under at the Baseband Version under Settings - About Phone. The last three letters will tell you which release of Gingerbread you have. In my case the baseband is I9000XXJVR, so I have JVR.
If you already have JVQ or JVP, you can flash the kernel and then Darky's Rom directly. Just don't forget to backup everything.

Custom ROM for P990"H"

Hello...
Since there isn't a P990H specific forum or ROMs available, I thought I would my questions here:
1. Besides the baseband (i.e. RF) side, are the P990 and the P990H same? How about P999?
2. If #1 is true, I assume I can use the custom ROMs for either P990 or P999 for P990H. I looked the CM zip files, and there isn't a baseband update included, so I am inclined to think I am right. Does anyone know for sure?
3. What would you consider the most stable custom ROM at the moment? Modaco FR19, or CM7? I am after the ASOP experience as much as possible.
I just bought a P990H (to be used with AT&T SIM), when it arrives, I'll be diving into getting a custom ROM installed and wanted to make sure I don't end up with an expensive brick.
Your help is much appreciated.

As far as I know, most of the p990 Roms and kernels are not compatible with the P999. You should see the pages of the roms you would like and ask their coders. if they are compatible.

OK... so, if the P990 ROMs aren't compatible with the P999 ROMs, how about the P990H? I've seen people with P990H who flashed P990 ROMs, but I am not sure if these are limited to a specific set of ROMs or all.

have a P990Hn and customs roms are working for me... The best working rom i found is the Modaco Gr2

Thanks for the confirmation! Did you just follow the same instructions as the P990H for loading custom ROMs?
I would love to hear your assessment of the Gr2. Is there any glaring thing that doesn't work?

By the way, are you using the stock baseband, or did you update it? If you updated, which one would you recommend?

Everything is the same! No special instructions to follow
And everything is working on this rom and it's been pretty stable for an alpha the only issue i had it was because i didn't wipe before and after the rom installation.
There is also a Gr3 comming at the end of the month so it's only getting better

No change on the baseband, i use the stock one
From the research i made it look like the only difference between these phones are the frequency they can work on (yours is on 850/1900 i think) other than that i don't think the modem on those phones are different.

i was looking for some info as well. does flashing a custom rom change the baseband or 3G bands of the p990h?

No, if you dont update the baseband (and you shouldn't) then you'll be okay.. You should probably also save the RIL from original ROM (and put back to the new one) so that everything is working as it should. the RIL is located in /system/lib/lge-ril.so

Thanks For the info guys

1) you cannot flash Custom ROMs if you are not rooted....
2)Phone Recovery is available only with root and with CWM
3)Different regions,service providers and devices have different responses for BBs. Generally, the most popular ones are V20q, V20C and V20S for the stock ROMs and the corresponding RILs
4)Performance will change with different Kernels, BBs....such as Voodoo, Battery performance, Scrolling etc
If you like the stock based ROM, then I would suggest you to reach out for Django Manouche 1.5beta4 ROM which is on XDA Server...check for the thread....and choose Stefan's , Flix's or Spica's Kernel.....each are valuable in their own ways.
Hope it helps you...CHEERS mate...you have one of the best devices in your hand

Thanks you both but does those roms show when there are new updates?
Also in case I install this one, whats the difference between this one and my 20a? Does it have italian bloatware?
Thanks
I will guess I will root my phome just for backups and chainfire
One last question,if I install this rom and have another bb or kernel? Will it work bad?
How do I install those roms, by cwm?
Good luck

you have to root your phone mate...thats the first step in liberating ur phone.
STOCK ROM usually has a lot of bloatware and Custom ROMs are slimmer by removing unnecessary apps....so you can go for a Custom ROM without worrying about bloatware.
I had suggested you a custom ROM and this does not have any issues with different BB or Kernel...only thing u have to keep in mind....use Kernel made for Stock ROMs.I am using a V20C Baseband with the DJ 1.5beta4 ROM which is based on V20S sources...check my signature and you will have more idea.I am using my own Kernel too.
for CM7/CM9, you can use any BB but the RIL has to be only from Froyo...means V10 series RIL.
Custom ROMs are mostly flashed using CWM. Updates- some of the ROMs are updated by ROM manager....but my opinion is to download and flash manually. Some of the ROMs do not use the OTA tool for updation(honestly....this is better)
IMPORTANTLY MY FRIEND, read through the opening posts from custom ROM and Stock Kernel threads....and use search....you will know more information.
Hope this helps.Thanks and take care
