5 Rookie questions needing 5 answers please read!!!!

Hi guys,
Im thinking of flasing a custom rom using odin.
Im running stock froyo 2.2.
PDA: I9000XWJPA
PHONE: I9000XXJPP
CSC: I9000XEEJP4
My phone is rooted and lag fixed. I understand that i need to remove the lag fix before and flash.
I updated to this using the registry hack. My questions are as follows...
1) Can i flash a custom rom from stock 2.2 or do i need to firstly flash a kernal with recovery 2e and then flash a custom rom?
2) Am i right in thinking that the PDA is the right bit to be looking at i.e when people say this rom is usable with JPA / JPO etc. The phone and CSC are not important when flashing a custom rom ( but still needed obviously )
3) If by some miracle of god we ever do get 2.3 and i flash back to stock Froyo via odin using a rom from samfirmware.com, will kies recognise my phone? Or will i forever be destined to flash "unofficially" through odin.
4) Looking at the PDA etc given above can anybody recommend a good rom to flash with gingerbread theme and apps. ( i keep seeing Darky's rom popping up in conversations ) and also have a link to it if you would be so kind. Im not lazy but theres so many roms all over i want to make sure i get the right one.
5) Once i have recovery 2e can i flash future roms over the top using rom mananger by clockworkmods and not have to go through odin? Or how does that work?
If i could get some clear answers to the above that would be great.
Yes i am a newbie at this but i am confident that i understand the basics, its just a couple of things above that i want clearing up before i proceed.
I know how to use odin correctly. ( close kies first / make sure odin opened before plugging in phone etc. )
P.S Yes i have 3 button recovery and download mode.
Thank you for taking the time to read this and a big thank you to any body that takes the time to respond with help.

Any body that can help?

dude i feel your pain. i've rooted and installed custom roms on two other phones, most recent the HTC Desire Z. and it was quite a nightmare to just start off to know what the first step is, there are soo many different guides its hard to know which is what and what has now been superceeded by something else!
now i'm trying to get a custom rom on my galaxy S too, but really having a hard time understanding everything becuase guides and stuff are so different for different roms, gets confusing and dont know which one is for me!
my phone is already rooted, i have firmware 2.1-update1, i know i have voodoo lagfix somewhere installed. but my base band version is I9000XXJM4, which i hav'nt seen in any guide! where did you get your seperate PDA, PHONE, CSC info from?
sorry i could'nt help you and i justed added a bunch more questions to mix
also how did you manage to get Clockwork Recovery on your phone? i have recovery 2e atm. i downloaded Rom manager from the market and tried installing Clockwork rewcovery, but first it would not even download. then i tried next day and it downloaded it through rom manager. but i dont think it installed it. i went into recovery mode and then it tried to auto-install clockwork recovery in recovery mode! but it just hanged at zero status bar for like 20 mins. i turned the phone off and on, went back into recovery mode and it was still recovery 2e, how do i get clockwork recovery to flash as the recovery mode?

Type *#1234#into your dial pad and it will come up. If I'm right I believe that 2.1 is more simple to flash over than 2.2 which is the bit that's confusing me.
I believe that you would need to flash a new kernel with recovery 2e and then flash a new Rom over the top.
I'm a but confused though as to weather or not I would need to flash back to 2.1 and then do a couple more flashes to get the job done.
Can some one please clear this up.

1. You don't need to have 2.1 rom to flash, since you'll be able to do all the flashing using Odin and download mode. Just flash a kernel, using odin, that has clockworkmod integrated, and you'll be able to flash most roms and kernels with the clockworkmod.
Speemod kernel is a great kernel, and has clockworkmod included.
Link: http://forum.xda-developers.com/showthread.php?t=822756
2. PDA is the rom part. CSC is important when using stock roms. I think that custom roms have CSC included in them.
3. You'll always be able to flash with Kies by using the Kies Registry Hack or by flashing a stock rom through odin. Kies will recognise your phone even if you are on a custom rom, but I'm not sure if it'll flash your phone.
4. I prefer Docs Ultra Slim roms because it's light, and you can customize them however you want. Darky's rom is a good option if you want all the features of a stock rom, and more. I use a Gingerbread theme with Doc's rom.
Links,
Darky's: http://forum.xda-developers.com/showthread.php?t=814091
Doc's: http://forum.xda-developers.com/showthread.php?t=817703
Both can be installed through ClockWorkMod
5. I think I answered this already.

Thank you for clearing that up. Very helpful but unfortunately you now raised another question haha.
You said that I would always be able to flash through kies using the registry hack... but wasn't that disabled so the registry hack wouldn't work any more a couple of versions back on. 803 or whatever it is?
And you also said that kies would recognise my phone but might not flash it which if I'm reading it right.contradicts.what you said about always been able to flash through kies.
Thank you so much for previous post it was very helpful.
Sorry if I sound stupid for.asking so many questions but I want to make sure I have covered all the angles before I proceed.
Again thanks for taking the time to help.

By registry hack, I really meant the Kies Registry Patcher app found here: http://forum.xda-developers.com/showthread.php?t=835628
Works on all Kies versions at least for now.
Like the original registry hack, this using this app makes Kies think that you have a stock rom and as long as Kies thinks that you have a stock rom, it will flash your phone.
In the sentence where I said that Kies will recognise your phone but won't flash, I mean't that it wouldn't flash without the Registry Patcher.

Thank you sooooooo much for your help dude.

[Q] Bell i9000m and Ginger bootloaders - safe?

Hey,
I skimmed through the forums and saw various posts about people asking what ROMS were safe for the i9000m but haven't seen anything about sbl.bin
As most of you probably know, the i9000m was plagued with sd card corruptions pre JL2. Then, that miracle FW introduced a new sbl.bin that solved some stuff and the sd card corruption went WAY down. Now, with the arrival of Gingerbread and new bootloaders, i was wondering if it was safe to use these new bootloaders on our i9000m devices and still benefit from that miracle cure that the JL2 bootloaders provided. Its pretty much the only concern i have thats stopping me from going to Gingerbread.
Thanks

I'd also second this question but add on to it the following:
boot.bin
sbl.bin
Both safe?
In addition:
Can we go back to eclair/froyo if we want, in order to reflash official from kies in Canada?
Can we use our own CSC?
Does this support the 850 band, or do I need to flash the KC1 modem?
Will the phone die?
We thank you all for your time

1. yes
2. no
3. yes if you use the method here: http://forum.xda-developers.com/showpost.php?p=12156313&postcount=438 or just keep using JL2 or KC1 modem
4. mine hasn't yet, been on gingerbread for about a week or so now

moved to gingerbread and can't see why you would want to go back to an earlier firmware.
custom rom and especially a custom kernel transform the phone completely: much faster, much better functionality and better battery life
you can still connect to kies, but why? odin and cwm provide a much better means to upgrade and change firmware and open source development is much better than anything Bell will ship
things to realize: (1) the sgs is incredibly resilient and robust, most "bricks" are not bricks at all but recoverable with download mode and reflash (2) there's lots of expertise to see you through every situation and every rom chef and kernel developer has its loyal fan base, so try for yourself and find the combination that works best for you

do we need to update the bootloader if we come from KC1 and we want to upgrade to JVH?

not to use kc1 modem with JVK rom no: but if you are coming from 2.2 froyo rom to 2.3.3 gingerbread JVK rom, you need bootloaders to move from the 2.2 rom to the 2.3 rom
the sequence is:
1.change rom from 2.2 to 2.3 stock JVK with GB bootloaders (see http://forum.xda-developers.com/showthread.php?t=1047924)
2. change stock JVK rom to custom JVK rom (deodexed, zipaligned and rooted) using cwm sd card zip method
3. if desired, flash compatible performance JVK kernel (using odin or cwm) note: many roms include kernel, check features list -- this step is only to replace the included kernel that got you rooted or to swap it out for one that has different performance features (speed, battery life etc)
4. activate 850 mode in JVK modem or reinstall KC1 modem (flash in odin or use cwm sd card zip).
5. go into cwm recovery, perform backup and then add custom modded theme if desired -- do the backup of the full functioning system before doing theme changes, that way if anything goes wrong you are starting from the completed install and don't have to repeat everything!
5. load titanium backup and restore apps: use market to update and then set up your launcher
6. do another backup!
Seems more complicated than it is. Along the way if anything hangs step 1 is always pull the battery and reboot. If that doesn't do the trick, step 2 is pull the battery and use the 3 button control to go into recovery mode, reflash and reboot, and if that doesn't work, use the 3 button control to go into download mode and reflash the part that hung, and if that fails, go into download, connect to odin and start at the beginning!
shamelessly stolen from all the good guides that dot the xda landscape and a surfeit of trial and error!

Here is what I did. At first I was on KC1 (updated trough kies). Later I flashed a 2.2.1 JS8 based ROM, without modem or boot loader (so these two were still KC1)
I wanted to try gingerbread. So I flashed the gingerbread starter through heimdall (boot loader and kernel)
I booted in recovery and installed my custom JVH ROM (took the rooted deodexed JVH ROM, removed a few stuff, edited gps.conf for north-america and replaced Swype with a fr-CA enabled-one), upgrading the kernel (to default JVH) but not the modem.
So my modem is still KC1 (850 MHz working out of the box) and JVH works fine.

You can use this procedure (as stated before) and use the latest modem with 850hz support
http://forum.xda-developers.com/showpost.php?p=12156313&postcount=438
I got JVH running with a full flash and 850hz

What exactly does the 850 band give us? I've never switched anything on or off in regards to bands/modem and my phone has always given me a signal and a data connection. What exactly do you get when you enable the 850 band? Also how do you know if it is enabled or not?

Some places in Canada have poor or no 1900 MHz coverage. In this case you will want 850 MHz.
I noticed my phone used 850 MHz mostly indoor and in rural areas. To check you need to go in service mode (I don't remember the code by heart but it starts with #*#*)
@t1mman
Thanks I know but I think it's easier to say on KC1 as I have no problems with this modem.

no problems
been on jvb for a week with zero problems, this phone was previously sent in for repair prior to 2.2 jl2 release... so things seem to be good... i flashed ugkc1 modem for 850 band

How to revert to stock kernel

I have a Bell SGS, GT-I9000m. I'm considering installing hardcore kernel only, i.e. no custom ROM. If later I want to revert to the stock kernel, how would I do that?
Thanks for your help.
Sent from my GT-I9000M using XDA App

I'm not quite sure if it is possible with the stock-kernel but if you can make a full backup (like with CWM) you could restore it later. But why do you want to get back to stock-kernel?
If the backup-possibility does not work you have to find the stock-kernel for downloading and flash it via Odin or you have to flash the whole stock-ROM with Odin.

Thanks for your answer. I can't make a Nandroid backup while I'm on stock (because I can't install CWM recovery because I'm on 3e stock recovery, not 2e)
I'm not sure why I would want to go back to stock... Maybe something goes terribly wrong? I guess I just wanted to know if it was possible.
Last question: when you say I would have to find the stock kernel, is that just Google, or are there sites/repositories out there for this sort of thing?
Sent from my GT-I9000M using XDA App

I should add, the site/repo question is for kernels and stock ROMs...
Thanks.

Well, then just flash the whole stock-ROM and flash it (look at samnfirmware.com for firmwares).

Don't know if you'll find it anywhere cause nobody needs it.

Possible scenario
Alright, thanks for your help. I guess the one scenario that is bothering me is as follows:
1) Bell - FINALLY - releases their official Gingerbread update.
2) I've installed Hardcore kernel, which according to - http://forum.xda-developers.com/showthread.php?t=822756 - "works on all 2.2 and 2.2.1 ROMs".
3) Would I be able to install the Bell Gingerbread update with Hardcore kernel?
This is why I keep asking how I would revert from Hardcore because I obviously don't want to lock myself out of Bell updates forever.

It doesn't matter which kernel you are using when you are flashing with Odin. And Bell releases the updates later than Samsung, so you'd have the advantage of getting updates earlier with a 'free' firmware.

One solution to flash back the stock kernel is to extract the zImage (the kernel) from the stock rom and flash that with Odin or Heimdall.
But as far as I know having a custom kernel would not cause problems with installing a stock upgrade.

Done
I've installed Hardcore's kernel. Everything seems to be working fine, phone started up and picked up service.
I booted into recovery, enabled lagfix, turned on all of the recommended tweaks and then ran the Quadrant Standard. Things seem a bit faster, so I guess it's all good.
Next step, Darky's 10.1.
Thanks for your help, everyone.

One more question:
I did a Nandroid backup of everything (so data, dbdata, cache AND system). The restore option says "Be careful!". What's up with that? I mean, what's the caveat?
Thanks.

I've already made some NANDROID-backups, but never seen 'Be careful!'.
If the backup was succesful I wouldn't care about that.

*sigh*, I hate to keep adding questions on to this thread, but I must.
After installing the hardcore kernel and enabling tweaks and lagfix, I'm running into exactly this problem: http://forum.xda-developers.com/showthread.php?t=851970
My phone was extremely hot for a while, then I got a warning indicating that my internal phone storage was running low, etc.
Eventually, I found this file (/data/local/tsprsp) to be the culprit. I deleted it and rebooted and now my phone is fine. However, vibration just doesn't work at all!
Any ideas? Has anyone else run into this problem?

I was told that if you do a 'full' backup, in some cases restoration will fail with some error. But it depends on the version of the ROM you are using.
That is the reason why it is recommended to backup only data and if you want to restore, then first reflash your rom, then restore the data.

Thanks, zsori. That explains the "Be careful!".

you will have to flash back a stock rom via odin if anything wrong happen during the flashing of custom roms, although chances are low if you follow the instructions carefully.
good luck and have fun flashing custom roms!

Which Gingerbread?
So I'm continuing my quest to learn more about all of this custom ROM flashing stuff. And I wanted to get gingerbread on my phone... So I figured I'd just get an image from samfirmware.com and flash it. But then, I went here (because I was also interested in Darky's 10.1 so I was reading their guide): http://www.darkyrom.com/community/i...-darkyrom-gingerbread-jvh-noob-friendly.3080/
It says that flashing "Ficeto_JVH_I9000_Odin" will get me a stock Gingerbread. My question: what's the difference between flashing an image from samfirmware.com or flashing "Ficeto_JVH_I9000_Odin"? How do I know which to pick?
In all my browsing/reading, I realize that there are 3 "separate" parts: kernel, modem and then the "ROM". Ideally, I want to keep my modem as is... What does that correspond to in Odin? I've tried to find what "PIT", "PDA", "PHONE" and "CSC" represent in Odin, but I'm not sure I got it right. PIT = Kernel? PHONE = modem?
And finally, how do I know if a particular kernel is compatible with a particular ROM?
Sorry, I know there are lots of questions there. But please help clearing up a n00b's confusion. Thanks.

you got it wrong.
PIT is for mapping the partitioning of the phone. In most cases you should only use 512 pit file. and only use it when you want to wipe the phone.
the three parts is "pda" (which is the rom), "phone" (which is the modem), and "csc" (which is the carrier customization and apns)
the kernel is in the part of pda (the rom)
check the thread in xda of the kernel to see if its a gingerbread kernel or froyo kernel.
hope this clear things up

Yes, that helps. That's really good to know. So now, in Darky's guide to flashing Flash Ficeto_JVH_Odin, I see that only PIT and PDA are specified. This is reassuring, knowing that the modem and carrier stuff isn't touched.
Many thanks.

There are firmwares with three parts (Phone, PDA, CSC, including bootloader) and with only one part (PDA, no bootloader(?)). The one-part-FW is just an 'update', the one with three parts an 'upgrade'.

[Q] I9000M 2.2 UGKC1 to 2.2.1 XXJPY questions

OK, so I've been reading guides, FAQs, how-tos, and various forum posts, and thought I had a pretty good handle on how to flash FW to this machine. So, last night I backed up everything important, and downloaded from here ( http://forum.xda-developers.com/showthread.php?t=1102881 ) the following:
2.2 UGKC1/UGKC1/BMCKC1/Sbl. This is the stock FW as currently installed on my I9000M from upgrading through Kies.
2.2.1 XWJS8/XXJPY/OXXJS5 (MultiCSC) (no sbl)
So just as a sanity test I first tried flashing the UGKC1 PDA file over to my I9000M using Odin. This worked as expected, since it's the same kernel.
Next, I tried to flash over just the XXJPY PDA file over to my I9000, using Odin. No re-partition, no PIT, no modem or CSC. No go - it just repeatedly displays the GT-I9000M screen and never boots the kernel. Couldn't get into recovery mode from this state, but was able to access 3-button download mode.
So, tried flashing over the 2.2.1 XXJPY PDA, Phone and CSC files. Same as before - no actual boot.
I flashed it back to the 2.2 UGKC1 PDA, phone and CSC files, and did a factory data reset and cache clear, and everything was fine running 2.2 again.
From reading here it appears that others have successfully installed 2.2.1 or even 2.3.x kernels on Bell Canada GT-I9000M phones. So, what important step did I miss?
Do I need to re-partitiion? Do I need to use a 2.2.1 FW that includes the boot loader?
For now I'm OK running 2.2, but would eventually really like to be on 2.3.x and don't want to wait for Samsung to make 2.3.x (what happened to 2.2.1) available to GT-I9000M phones. I'll leave it alone for now as I'm going on vacation in a couple of weeks and don't want a hosed phone.

What happens if you flash just a kernel like CF root or speedmod? My only other thought is to redownload jpy and try again as maybe the download was corrupted.
Also with another kernel like speedmod you could download and install a custom rom on cwm (clockwork mod) via recovery that is 2.2.1
I've had some problems with 2.3.4 (never tried 2.3.3) so I am back on Froyo for a bit until things get sorted out a bit more.
G

I don't know if there is a suitable version of CF Root for the UGKC1 firmware - they mostly seem to be oriented to the more international versions. As usual, in Canada we get something a little weird. Don't know about speedmod.
I don't think there should have been any problem with the downloads, as the files themselves are in md5 format, which means they are getting verified by Odin 1.8 when it goes to use them, as I understand it. If they were corrupted Odin should complain about it.
With the announcement ( http://forum.xda-developers.com/showthread.php?t=1158492 ) that Gingerbread is supposed to get an official release to Bell phones soon (which mine originally was), I might just let this lie, for now.

There is a gentleman on youtube by the name of AndroidGalaxyS (original, I know) that has some excellent and detailed walkthroughs and reviews of various ROMs for the I9000M.
youtube.com/user/AndroidGalaxyS
Specifically in your case, you'll want to watch this one that shows how to install 2.3.4 JVP:
youtube.com/watch?v=cLXQn0gOBuA&feature=feedu
Good luck.

I agree that the source maybe lacking. I just found out that the JL2 firmware from samfirmware.com is missing db_data file so I would always get an error after flashing that. KC1 would also not always boot for me so it might be missing something too.
That said what are you trying to accomplish? If you are just trying to go to another stock rom I'd just leave it and put a custom kernel on to give you root and CWM recovery.
Most any other Froyo rom is flashable from CWM in recovery and you do not need to worry about odin except to recover from bad things and it looks like you can do that. Gingerbread is different because they changed the bootloaders and that means Odin.
Of course its getting harder to dig back and find those Froyo roms since the rest of the i9000 world has been on GB for a while.
G

Thanks for the replies, so far. Mostly I was just experimenting, and trying out XXJPY was just a first step in my experimentation before moving on to GB. Part of the reason for this is that it seems like a lot of the modified kernels and so on are meant to be flashed over certain versions of the firmware, and those versions don't include the Bell/Virgin-specific ones. Or maybe I've misunderstood how this stuff works.
Yes, while my attempts to install XXJPY have been a complete failure, even when re-partitioning with a PIT file, when I re-flashed back to the stock UGKC1 FW everything was fine.
At this point I'm just trying to get a better understanding of where this went wrong. I've never specifically updated the SBL - the JPY package I installed didn't include it, and I didn't check off the "Update boot loader" box when re-installing KC1.
I've seen a number of posts here from people who updated I9000Ms to other FW, but unfortunately they don't seem to have detailed exactly where they started from, or exactly what they installed, or how.

[Q] Roms with GKG3 based firmware

Hey everybody,
Im kinda new to droid development, and have played around with it a little (flashing roms, kernels, rooting etc) however, im curious why there are roms based on pretty much every other firmware other than GKG3. I might sound like a n00b for asking about this but its mainly for my knowledge. I figured KG3 would be fairly common as it is one of the North American firmwares, but I must be incorrect? Anyways any insight on this would be great. Also a quick question, seeing as I am a Bell I9000m SGS owner does it matter if I put firmware from say Europe on my phone? I have noticed that my signal decreases when I put a rom on that is JVR based? Curious if this causes my phone, seeing as the modem is being changed to JVR, to think that I am out of country and will inflict long distance charges. This probably sounds like a dumb question, and I dont really believe LD charges will apply, but some confirmation would be nice as google didnt really help me out on this one.
Thanks!

KG3 is 2.3.3 and although it was just issued to Bell and other N.American customers, the rest of the Anfroid world has been using 2.3.4 for 6 months and some have moved to 2.3.5. The roms you see here are cutting edge and most use the latest firmware. The last official and stable release was JVR a 2.3.4 firmware and there are many good roms for JVR. It is easy to keep your KG3 modem in place and the KG3 CSC file and just upgrade your system to a custom JVR kernel and JVR rom.

I tried flashing galaxian's jvr kernel and it just bootlooped so maybe I'm doing this wrong? I kept my stock modem and CSC, flashed kernel using oden, factory reset was done as well as a cache clear prior to the flash and all I'm getting is a bootloop so I'm not entirely sure what I'm doing wrong any advice would be appreciated! And again thanx for the info in the previous post!
Sent from my GT-I9000M using XDA App

yes you flashed just the kernel, you must first flash the stock rom and then any custom kernel for the same firmware -- you need the stock rom to install the correct bootloaders prior to flashing the custom kernel
so in odin, flash JVR stock in pda, KG3 in phone and CSC
tick auto re-boot
then flash the custom kernel of choice in odin under pda

Awesome thanks for the tips! Will give this a try

Hi guys - you guys might be able to help with a wee problem.
upgraded FW today via kies to 2.3.3 KG3 from froyo 2.2 with speedmod kernel.
in the process though i lost root but worse is i now don't have 3BR, when i used to. I still have 3 button download mode though.
I want to root again and flash a different kernel (for root but also for performance/tweaks) but worried to without 3BR ie. how will I access tweaks/enable root etc without it!?
Any ideas/advice please? Thanks

first flash a complete 2.3. firmware, either 2.3.4 JVR or 2.3.5 JVT. This should re-install basic 3BR functionality. I think you have not got the necessary bootloaders in the jump from froyo to GB and a complete stock install should correct this. Do tick re-partition and use 512 pit, do check auto-boot: let the phone boot and right itself. Check for 3BR and do a system reset.
Then flash KG3 modem and CSC. Your phone should then be functional.
Then flash a kernel with root inbuilt to it.
If you use the GTO Tornado kernel you can also clean your system completely as this stage instread. If you use another kernel, do the factory reset, davlik cache clean etc. prior to flashing the kernel as suggested above.
Do the clean prior to re-installing your apps.

Thanks! will give this a go but have only ever really flashed a kernel before with odin so want to be doubly sure about these steps if that's ok? apologies for my noobish ignorance
- only found a 2.3.4 JVR at samfirmware - getting this and the 512pit file. This should be fine?
- then flash a KG3 modem and CSC - any idea where I get those files from? - the ones i've got now i only got through kies (and when i do get em, when i do this in odin do i only use the phone/csc boxes and leave pit empty/uncheck re-partition?
thanks again mate.
Edit: forgot to say my reason for questioning the JVR is because the one i have is listed as European...where as I have a bell mobility but in australia - does this matter? latest FW for aus/america is JVN 2.3.3

no problem: always better to ask for help first then assitance fixing a problem when it all goes pear shaped.
There is a thread on the KG3 firmware with lots of these questions answered: http://forum.xda-developers.com/showthread.php?t=1211939 and also the basic resource for firmware posted by Ramad here: http://forum.xda-developers.com/showthread.php?t=1102881 -- scroll down and you will find KG3 under N.American, he also has a nice set of illustrations for using odin.
You can also source a cwm zip for the KG3 modem from perka's stash here and on the market (free app) -- useful to havce the modem in cwm zip form as then you can just install a new stock firmawre such as JVR or JVT and add the modem in recovery.

Thanks so much again - that looks like a hefty bit of reading to be done there via your links so before I do that, just one more Q please - and apologies if the answer for this is somewhere in the links you've provided.
i was just trying to read up about why the samfirm file extracts only to a single .tar file called JVR_JVR_JVR and how to use that in Odin and came across this thread:http://forum.xda-developers.com/showthread.php?t=1075278
my Q is - in this thread he makes a strong point of stating not to tick repartition and not to put the .pit file...but you say to do so.
am i missing something obvious?

well different people different perspectives on re-partition and pit.
Tick re-partition and flash the pit file. Leave it un-ticked and do not flash pit file. That's the only key: do one or the other.
As I understand it, the reason to re-partition is that it re-sets the base file system upon which you are now flashing the stock firmware -- seems a basic step whenever you move firmware versions e.g. 2.2 to 2.3, 2.3.3 to 2.3.4 to 2.3.5 -- not so much if you are installing a rom or kernel within that family of firmware.
Since I always then convert the file system to ext2 to speed up the system and I use damain's kernel to clean the system, I do use the pit file whenever I flash a new stock firmware to clear the basic file system and further aid removal of legacy files that could complicate the install.

BTW the samfirmware files do extract using 7zip into the component parts for use in odin: pda (rom) phone (modem) and CSC. You then flash a custom kernel in the pda section if you use one for performance and root.

thanks lgssheddon, for the info here and in the PM.
Will crack on now with reading all the links you provided.
I just have to say a big fat D'oh! - why oh why could I not find the answer to what was bothering me most ie. apparent loss of recovery mode. The very first post in the first thread you linked gave me the answer - that it is now a 2BR (and tried it on my phone et voila, by magic I can get into recovery again!). Don't know how I could not find this thread even when I searched "KG3"!!
Thanks again for your help. i'l llet you know how i get on once i digest all this info

Hi guys - you guys might be able to help with a wee problem.
upgraded FW today via kies to 2.3.3 KG3 from froyo 2.2 with speedmod kernel.
in the process though i lost root but worse is i now don't have 3BR, when i used to. I still have 3 button download mode though.
I want to root again and flash a different kernel (for root but also for performance/tweaks) but worried to without 3BR ie. how will I access tweaks/enable root etc without it!?
Any ideas/advice please? Thanks

The 3 button recovery has changed for KG3. I believe it used to be upvol home and power. I do believe now it is volup, voldown, and power. This should work for you to get you into recovery to flash whatever you like. Also the samfirmware for JVR is branded with Swisscom and doesnt work very well for using it with a KG3 modem and CSC, with my experience anyway. I would recommend to go to a JVQ PDA and use KG3 for your Phone and CSC. Also after you have installed this make sure to check what your country code is and install it. Hope this helped

The firmware that he is referring to doesn't. It is only one file meant for the PDA section of ODIN. Not entirely sure why they did this but i was running into problems with it as well. If you know how to play around with the core files you could in theory extract it to its root and put multiple files into .tar files (ex. select factoryfs.rfs, param.lfs etc. and place it under one .tar) but thats a lot of playing around and potentially dangerous if not done correctly.

not sure which download you are referring to but there was a branded version of JVR and a generic one on samfirmware: I have the one that does not have the swisscom logo and it certainly was extracted by 7zip into its component files (pda/phone/CSC) as they are still on my pc in that format.
You can also source stock firmware from Ramad's thread.
And I stand by my comment that for anyone using KG3 as a modem, JVR is the most stable official release available, much better than JVQ. JVT has a lot of promise and will be a better firmware than JVR but it is not yet had all the bugs sorted and while there are Gold Rom version for JVR any JVT rom is still at a beta stage and should not be used yet by someone just starting to flash custom firmware (IMO).

Hi again,
Q for lgssshedden really but if anyone can help i'd appreciate it!
have had 2 crashes now with Tornado Aureus RC1 - few little bugs/glitches eg with ringtone changing etc then on a reboot it won't go past the Tornado start screen with the big flame.
First time I just reflashed stock KG3 then reflashed the Tornado kernel, no problem. This time when I try to flash the Tornado kernel (either Aureus RC1 or Gold) it just bootloops at startup even though the flashing seems to go ok.
So now i'm back to (yawn) stock KG3 2.3.3. Really just want to root it again but with Tornado not seeming an option i'm finding it hard where to turn to root.
Thanks in advance!
