[Q] How to downgrade? - Galaxy S I9000 Q&A, Help & Troubleshooting

How Do I downgrade from 2.3.3 [JVO] to 2.2.1 [JPY] using Odin? How do I fully downgrade it all, bootloaders etc?

well you need to find a froyo ROM with bootloaders - if you updated them when flashing GB 2.3.3
ideally you want a froyo ROM with all 3 files and a 512PIT, also with re-partition checked.
head over to www.samfirmware.com and have a look there for a 2.2.1 with all 3 files,
IT MUST CONTAIN BOOTLOADERS IF YOU CHANGED THEM !!!
alternatively if you cannot find a froyo rom with 3 files AND bootloaders. flash this first as a single PDA with NO pit and NO re-partition http://sourceforge.net/projects/teamhacksung/files/galaxys/GT-I9000_FROYO_FULL_PDA.tar/download
then flash a firmware with 3 files and pit
hope that makes sense ???

Yeah makes sense thanks, I upgraded via KIES so the bootloaders would of been updated too, Do you recommend choosing "Update phone bootloader" on Odin? or leave that blank ?

Gingerbread bootloaders work on froyo, but if you are down downgrading to go to cm/miui then you do need froyo bootloaders, nitr8 produced ezodin files to revert, search dev forum

[Q] Which version of ODIN3? UPDATE: Contains v1.82.zip

Looking to start flashing and obviously need ODIN3. There looks to be about 50 versions, http://www.filecrop.com/odin3-1.82.html
Which one do I need to work with my Captivate?
I have already used the oneclick for restoring my phone back to stock.
Ohhh... nice odin 1.82 didnt know about that one.
i just tried it its safe...
here ill post it
I used ODIN3 v.1.82.exe.
Cool. Downloaded. Now, where to obtain the correct .pit?
dont use a PIT!!! unless flashing BACK from gingerbread / CM7
every other rom eclair froyo custom have the same partitioning table. but some ROMS (eg the old rogers stock rom) are missing important files that SCREW YOU if you use a pit!
do not use PIT or check the re-partition (p in pit is partion) in odin unless you know you are changing the partitioning tables!

Where to find the official Bell Canada Froyo update?

I tried to update my Bell Canada Vibrant with Kies and I bricked my phone
I wanted to try the Odin method to recover my phone with the official Bell Canada Vibrant Froyo ROM but I couldn't find one yet... is there a place where I can download it?
BTW, does this ROM available in the update.zip format? I can get into the 3 buttons Download mode/Recovery mode no problem, so if such file exists I would like to try that first instead of the Odin method.
Failing that, is there a custom ROM that I can try on my Bell Vibrant?
Thanks!
Samfirmware.com has tons of ROMS. However you have to sign up as a member.
Download the XXJPU file. This is a 3 part compressed file that will need to be flashed via ODIN. You will need to check "re-partition". Also make sure you use the 512pit file. Once this ROM is flashed via ODIN, you will then download and flash the XXJL2 ROM (one file only). This was the last version Bell had. I hear KC2 is now out, which you can update via Kies.
I just downgraded from MIUI, and used this method about two weeks ago and all went well. From JL2 however, I flashed Darky's 9.5 and love the battery life and snappiness of my phone.
Although I'm not recommending you one custom ROM over another, In the past I have used Darky's 9.3, Ultimate ROM, Simply Honey and also cooked my own custom ROMS via romkitchen.org. I came back to Darkys ROM due to personal preference.
If you have any questions, or are looking for the files, I still have them on my computer and could make them available for you.

The official as in branded network rom that came with your phone unless you backed it up you will need a Google search .
Samfirmware does not carry many branded roms .
But i doubt if you will find one as nearly nobody saves them .
Possible work around is to flash stock 2.1 Eclair from samfirmware .
Then spoof registry to pretend its the correct ID and update to
Bell Canada Vibrant Froyo.
http://www.appbrain.com/app/spooffw/com.johnan.spooffw
jje
samfirmware.com does have the latest bell 2.2 UGKC1 available.. also search these forums you will find an odin flashable version. no you cannot us update.zip you need to use odin

Download stock gb firmware from ramad post.It contains gb bootloaders.Use jvr firmware it's stable.
Flash it with odin.If you want to use pit file check repartition.
After that download cf root and flash it as pda.Do not check repartition!
After that copy juwe rom to sd card and flash it through cwm.
Before everything remove sim card and external sd card.
Check my post in general it's called experience about rom and kernels maybe you can find usefull info.

thx 4 ur answer there!Is it possible jsut to flash only the GB bootloader?
Flashing stock GB and then Juwes takes about 2 hours
I thot u cud flash the GB bootloader on Froyo as TAR , but i cud be wrong
That's what I did when I updated my froyo to Juwe 4.3.1 several monts ago. I flashed with odin only the gingerbread bootloaders and just flashed the Juwe's ROM from the recovery. Anyway I strongly reccommend flashing stock JVR and a custom kernel and after that flashing Juwe 5.3 and it takes like 10 minutes + 20 more to restore your settings and applications and you're set to go.

NEWBIE HERE,

and how will i install it to my phone since i can't use Kies. or i could still use Kies?

umm 2.3.5 JVS is a leaked rom by darky teams so i kies might have it after few months who knows mayb a year?
if u want to update to 2.3.5 u need to flash ur phone via odin with 3 files and repartition tick along with PIT file for clean install...
hope this helps
PM if u have any other question

[Q] General Bootloader and Kernel Questions

Hello all,
I have a few general questions that I would really like some help with:
1.) I understand some bootloaders are not compatible with some ROMs. How do you know which bootloader you are running? How do you change your bootloader, must you use ODIN?
2.) How does the kernel come into all this, are some kernels not compatible with certain ROMs and bootloaders? When you flash a new ROM, does it sometimes come with a new kernel?
The main reason I am curious about this, is because I wish to flash the new Cyanogenmod 7.1 and want to be sure I am successful and do not brick my captivate. I am currently running Serendipity VII Build 2 and want to be as safe as possible when flashing Cyanogenmod 7.1.
Would the safest way be to flash to stock first using the following Odin one click method: http://forum.xda-developers.com/showthread.php?t=731989
Then from there, follow the instructions normally?
All help is greatly appreciated.
There are basically 2 types of bootloaders, Eclair/froyo and Gingerbread bootloaders. GB bootloaders are compatible with preatty much everything (not counting cm7 or MIUI).
Kernels are specific with a type of rom, example Boogs KH3 kernel worked with any rom that was based on KH3 (2.3.4). Some are tweaked specifically for a rom.
On CM7 and MIUI from what I can make out you can run it on either eclair/froyo bootloaders or GB bootloaders but some kernels are specific for bootloaders.
If you are on Serendipity then I am sure you used ODIN to flash i9000 boatloader (BL).
As the above person said there are eclair/froyo BL and GB BL....in GB BL we have captivate BLs and i9000 BLs. earlier GB roms used i9000 BL...then Samsung leaked captivate specific roms...so we have captivate BLs now..
All the one click Odins are used to flash captivate specific BL...
To go to CM7, many people flash it over GB bootloader and have no problem....but the safest way is to odin back to eclair/froyo stock...then go from there.....

Thank you for the help guys, I really appreciate it.
I will be flashing back to stock using the following method:
http://forum.xda-developers.com/showthread.php?t=731989
Then I will simply flash CM&.1 on top of that.
I will report back to let everyone know how it goes.
did your phone come with froyo on it/what is the build number of your phone? its a 4 digit number on a sticker under the battery, for example mine is 1010, meaning oct. 2010. many phones built later than this, and/or came from the factory tend to bootloop from jf6 (the firmware containedin that one click) and have also been known to lose button combos for recovery/download mode which would need both if you were bootlooping and for cm7.
if you have a later build phone it would be better to flash a leaked gingerbread firmware with bootloaders included and then flash a custom kernel with cwm included so that you can then flash cm7 from there.

I purchased my phone at the end of August in 2010. The only 4 digit number I can see reads " 0168", it is the largest number located behind where the battery is held. And yes, I have lost my three button combo for recovery/download mode. It stopped working, and I bet it was because I used that one click method you mentioned.
Do you recommend I flash this one:
http://forum.xda-developers.com/showthread.php?t=1129821
It says Cyanogen Mod users stay away, why is that?
or one from the official list, and if so, which one:
http://forum.xda-developers.com/showthread.php?t=1300843
Also, I am a bit unclear. After I flash one of the stock ROMs with the bootloaders, how can I then flash a kernel with CWM. Can I do it through ODIN?
And just out of curiosity, why can you not use these stock ROMs for everyday use? It seems we always flash other ROMs on top of these?
I know I asked a lot, I would appreciate the help!

You can use the bootloaders in the first link. At the time of that thread's opening, cm7 didn't support GB bootloaders. But, if your not sure how your phone will work with a1 click, I would recommend using the ones linked in my sig.
As for how to flash those roms, there are directions in the first post of their respective for flashing.
You can use a stock ROM everyday, most just prefer not to.

No one said you cannot use stock leaked rom as dialy driver, i actually used KH3 for some times and it was very good.
You should flash the kernel according to the rom you have flashed. For example, For KH3, there is a Boog's KH3 kernel with CWM. For all leaked stock rom, there is one click Odins and compatible kernels with CWM injected.
To go to CM7.1, u shud be on stock (Eclair/Froyo or GB) and should have CWM....

I need help too please. I have a Cappy that was originally on eclair 2.1 rooted. froyo 2.2 Kies mini update and rooted but didn't like it's battery use and slow action. I reflashed an Odin 1 click stock 2.1 back, rooted and then did a Gingerbread 2.3.5 I897UCKJ3_withBL_ Odin 1 click flash and am liking that quite a bit more. The only trouble I am having is rooting 2.3.5. I want to do the fugu kernal swap method with Odin3 zimage-root.tar then flash boog_KJ3_kernel3.tar. I can get into DL mode and hit the start button ok.
Here is the question I have. Where in Odin3 v1.83 do you load the kernal path? PIT,BOOTLOADER, PDA, PHONE or CSC. I can't seem to find a comprehensive Odin3 tutorial on my own and I don't want to flash the kernels to the wrong place. I don't think the first 3 options are right based on their names or info I have found. Can't use CWM till I get rooted so Odin or possibly Hiemdall are my only choices. I have Odin3.
HELP and TYIA
Bud
Kernels go in pda
When flashing a single file, unless its a modem or csc file, it will usually go into the pda slot. Modems go into the phone slot. Csc file is a no brainer. I've never saw anything that uses the bootloader slot on a captivate. Pit slot must have a pit file AND repartition must be checked. If you are flashing a kernel to get cwm just to flash a custom ROM, kernel goes into pda slot. If you want to user Odin to flash a modem, it goes into the phone slot. All files flashed in Odin must be a tar or tar.md5 file. Don't change the name of a tar.md5, it can cause a md5 check sum error.
There you go, cliff notes for Odin.
Edit
If I missed something or messed up something, please correct me.
Found Odin3 Answers. Yeah!!!
Studacris,
Thanks for that. Didn't see it before I found the below.
Sorry for the Noob impatience but there is a lot of info that won't show in a search right away. Anyway there is a cool little short video by 4-2ndtwin here on xda with a link here. http://forum.xda-developers.com/showpost.php?p=17788928&postcount=6 The system won't let me post outside links yet.

When ur phone boots up and u see the i9000 bootsplash, then u have i9000 Gingerbread bootloaders (we didn't have eclair/froyo i9000 Bls). Also, button combo to get into recovery or download mode is different with the i9000 gb bootloaders.
And if u try and flash an i897 gingerbread rom (and don't see the i9000) but u have a "pixelated" screen, then u have i897 eclair/froyo bootloaders. If ur flash to a gingerbread rom is successful and u see the i897 (att world phone) bootsplash, then u have i897 Gingerbread bootloaders.
