Hi All!
Just upgraded today my Galaxy S from Froyo to Gingerbread and I'm not quite happy about it.
Is there any possibility to rollback Gingerbread to Froyo?
Any advise will be appreciated!
Yes, it's possible to rollback. It's little trickier though because the Gingerbread bootloader vs the Froyo bootloader.
You have to make sure your filesystem is RFS and not EXT4 (lagfixed). If it's stock and didn't convert then it's RFS.
Then make sure you can get into download mode (Vol Down + Home then power and hold). If you can, these are the general steps you have to do:
1) go to http://forum.xda-developers.com/showthread.php?t=846913&highlight=stock and download the froyo stock firmware for your phone that comes with a froyo bootloader (this is very important because you'll be stuck in a boot loop if you run froyo on a gingerbread bootloader)
2) extract the file to a known directory
3) put your phone into download mode
4) start ODIN
5) plug in your phone while in download mode
6) check the options in ODIN like it shows in the picture under "How to flash with three files:" plus check "Phone bootloader update"
7) select the files you downloaded and select the proper PIT file (these are firmware dependant)
8) click start to flash
I say these are the general steps because I'm not sure which area you are in. If you can provide the current firmware you have by punching *#1234# in the dialer, we can give more specific infor.

Thanks a lot for advises!
Hmmm...that's weird are you sure this is right?

How did you upgrade it to Gingerbread? Was it through ODIN?
Grab a stock froyo FW from samfirmware.com (plug in the pda, phone, pit, and csc files) and make sure you repartition it in Odin to wipe your phone clean.
Hopefully you should be all good after that...

First you go to www.samfirmware.com
Download any 2.2.1 you prefer and flash it through Odin,
1 file or 3 files up to you prefer..

3files with repartition included is strongly recommended
and i recommend to flash XXJPU with 512.pit (tick repartition box also in odin)
ok here is step by step(xxjpu)
First you have to download XXJPU fw from www.samfirmware.com
1.wipe data/cache
2.get in download mode
3.run odin
4.choose pit as "s1_odin_20100512.pit"
5.choose PDA as "I9000XXJPU-REV03-PDA-low-CL747761.tar"
6.choose PHONE as "MODEM_I9000XXJPU.tar"
7.choose CSC as "GT-I9000-CSC-MULTI-OXAJPU.tar"
8.make sure you ticked "re-partion","auto-reboot" and "f.reset time" in option box
9.plug in your usb to a computer
10.press start
11.wait until it finished and your phone will reboot by itself
12.may be your phone will get into recovery mode automatically wait and choose reboot then
13.finish
i checked to see if XXJPU has a bootloader.....just in case and it has.
here's XXJPU : http://dl.dropbox.com/u/19506141/Stock - stock modems/I9000XXJPU (2.2.1).exe
and odin : http://dl.dropbox.com/u/19506141/flash en drivers/Odin_+_pit.exe
What's the difference between simple flashing and flashing with re-partition?
Galaxy S XWJVB
bump on this, can anyone confirm if this works?
and you need to check the update bootloader, JPU have the froyo bootloader
This works like a dream! Even tho am a newbie, I found it surprisingly easy!
hey i think you're on XWJVB.Do you have Android OS battery drain problem?I'm also on XWJVB but it sucks battery very quickly after playing gameloft games.(In Battery Use Android OS is above 60%)
Hi all,
I guess this subject must have come by, but i have not been able to find it using the search bar. So i hope some 1 can help me.
On my company we have 4 Samsung Galaxy I9000 in use, and 1 spare phone as backup.
Some of my collegue (and me aswell) changed our rom to Darky 9.5 and we are all very happy with it.
Now there is 1 phone that needs to return to the shop for repairs and i wanted to make a backup from the spare phone we have here. So i could flash his phone back to original rom.
I am from the Netherlands and the Rom that comes with the Phone is:
KIES says:
- PDA: JPC
- Phone: JPP
- Modem: JS2 (KPN(provider))
*#1234# says:
PDA: I9000XWJPC
Phone: I9000XXJPP
CSC: I9000KPNJS2
Is there a way to back up this Rom ? Or any other ideas on how to get this rom on the other phone ?
ty in advance for tips and tricks
well you could root a phone that is on stock ROM and make a nandroid backup and restore that on the phone to be sent back..
or you could go to www.samfirmware.com and find your firmware there and flash it using ODIN.
You have a 2.2 release, there is a 2.2.1 for this phone :
Code:
CheckFusDownloader_v0.5.exe -dl I9000XWJPC/I9000KPNJS2/I9000XXJPP/I9000XWJPC KPN

It's the official ROM is you try to upgrade your phone with Kies 2.0. You can try to install a SpeedMod Kernel before upgrading to format system and cache and wipe Dalvik cache, return in Download mode and Flash this ROM via Odin v1.3 in "One file Mode" (no repartition and no pit file, just the ROM in PDA file).
You need to have the 3 button combo working to do all this things to go in Recovery mode for "clean up" the phone via SpeedMod (no necessary but always good to do).

Ideal backup would be genuine original rom or genuine updated rom via Kies and back that up as stock factory rom .
I did via Kies registry spoofing and i believe that current Kies allows you to save firmware or at least its downloaded during the update and you save a copy before the actual update .

Ooh a kies registry spoofing. Hmmm will have to look that up tomorrow. Is that hard to do ?
Will i be able to put that firmware on any sgs ?

Hum, my reply make download on PC the OFFICIAL release on Samsung FUS server used by Kies 2.0 and it's a working method NOW. Registry spoofing doesn't work anymore !
Hi, i replied the topic on my phone. now i see the replies that came before the registry 1..
Ty all for helping me. i am gonna try some and let you know the outcome.

This worked perfect, many many thanks. Now phone is ready to be returned.
Hello,
It is the first time when trying to change ROM on my galaxy s. Before I start I want to be sure I take the right steps.
First of all some info about my phone:
PDA version is I9000BUJS3
PHONE: I9000BUJS1
CSC: I9000GATLJS2
I downloaded the ROM via Check Fus Downloader from samsung:
CSC: I9000GATLJP5
Phone: I9000BUJP5
PDA: I9000BUJP7
All I need to do now is to run odin and select the .tar file in the PDA field, correct?
Code:
Procedure:
1.Open ODIN. (And close Kies, if you have it open. It is important to have ODIN open BEFORE connection the phone via USB!)
2.Select the PDA/Modem/CSC/.PIT files in Odin. (For kernel flashes, only PDA is required. For FW flashes, .PIT and at least a PDA is required. Some PDAs have Modem and CSC integrated. Make sure you have the correct .PIT file. Usually 512.pit)
3.Check the "Re-Partition" checkbox. (Only do this if you have separate packages for PDA, Modem and CSC! Don't do this for single PDA flashes or kernel flashes!)
4.Turn the phone into the download mode by pressing and holding VolumeDown+Home+Power.
5.Connect your phone with your computer and wait until the drivers are installed.
6.When the drivers are installed, click Start.
7.The phone will be flashed and once it’s finished, it will boot up. (Do NOT disconnect the usb-cable, remove the battery or otherwise interrupt this process!)
8.You have successfully flashed your phone.
My phone was sim locked when I bought it ( now is unlocked, i suppose it will stay unlocked after upgrading).
Thank you!
Be carefull to flash firmware your phone need to be sim unlocked and network unlocked.Lot of people dont check this.See the post about it.
[email protected]
your phone will stay unlocked
and your instructions above are fine
should that fail - you may need a 2.3 rom with all 3 files instead of the 1 .tar file

How to know for sure? And if will fail it will leave my device in an unstable state?
And another question: Does the bootloader for 2.2.1 work with 2.3 ?
I think you actually need the stock FroYo bootloader to upgrade to 2.3? I may be incorrect, don't quote me. 2.3.3 has its own bootloader I believe.
I want to go back to gingerbread am rinning Dark Knight rom any help plz
Why God .. why ...
Flash stock through ODIN or Heimdall and thats it
If you had to ask this, it's probably a good thing you're going back to stock.
Sent from my Telus Fascinate running OneCosmics ICS!
why would you say that
Get stock ROM here.
http://www.sammobile.com/firmware/?page=3&t=1&o=1&m=GT-I9000&r=-1#modelsa
You need stock ROM (3 file stock ROM), Odin & Pit512.
1. Start ODIN.
2. Select the files into the relevant places in ODIN.
3. Click repartition.
4. Put phone into download mode.
5. Connect phone to pc.
6. wait for Odin to connect to phone.
7. click start.
8. wait for ODIN to finish & for phone to reboot.
You must have pit512 and click repartition as ICS uses a different file system to Gingerbread.
You may have a boot loop after doing this. I have had this occasionally. To solve this reflash with ODIN. This time make sure repartition is unchecked and don't flash pit file.
Sorry Screen shot says scs. I meant CSC.
Hope the following makes sense? I have tried nurmerious things through this great forum before posting!
1) Galaxy Samung S GTI9000
2) I put firmware on this last year now I have Galaxy 3 now I want to put stock rom back on galaxy s
3) I tried various stock roms but when I go into KIES it says its a KOR rom instead of UK rom and KIES wont update it
4) I them tried Check Fus Download to check I downloaded the right stock rom and let it download for me. It flashed ok via Odin3
5) If i go into about phone firmware = 2.3.6 baseland = I9000BUJV4, Kernel = 2.6.35.7-I9000BUJVG-CL71281 [email protected]#2. Build = GINGERBREAD.BUJVG
6) When I plug this into KIES it says "you device does not support software upgrading via Kies - Current firmware version: PDA:JVG / PHONE:JV4 / CSCV:JV5 (KOR)
Can some please help were i'm going wrong
And thanks for this forum its awesome!!!
you can flash stock firmware with odin
When I used the downloaded stock rom it flashed it sucessfully? via odin
You got wrong stock ROM.
Go to www.sammobile.com
Over there, select device (I9000), select region Europe, then select a ROM corresponding to UK or Great Britain (in the column country) and download it. Flash via Odin.

Tried as above used odin and it flashed ok, now when i check about phone it has the following firmware = 2.3.6 - baseline = I900XXJW4 KERNEL= .6.35.7-i9000XXJW4-CL1043937 [email protected]#2 AND BUILD NO:- GINGERBREAD.XXJW4
After it completed sucessfully I wiped the cache and reset the phone all came up ok, but whne i connect it to kies it still says PDA:JW4/PHONE:JW4/CSC:JW5 (KOR) Your device does not support softwareupgrading via Kies - Any help would be apprieciated
Because jw5 is a non official firmware( the laterst release) and there is no official release for sgs.i think the last official release is jvu
You have to flash the right stock ROM that is available in your country.
Download the right ROM for your country and flash it and make sure its not a custom or modded ROM.
Hope this would help.
