[Q] Restore Galaxy S back to Original Android 2.1

Hi All,
I Upgraded my Samsung Galaxy S to Froyo 2.2. All seems well but the performance does not seem all that great as well.
If i want to restore back to the Standard Manufacturer Firmware (i was on JG4) that comes out of the box with the I9000 what do i have to do? Any help here would be appreciated.

Download the firmware from samsung-firmwares and flash your phone with odin. There is plenty of flashing tutorials about to show you how to do it. Although if you managed to update to froyo then you properly already know how to flash it again

Hello. I managed to get the firmware from samfirmware.com for the original 2.1 (Asian version) but I couldn't get it to follow through. There would always be an error with regards to MD5 or something. What do I do? Thanks

I have the same problem as well, any helps here please?

Alot of the the DXJG4 firmware out there is corrupted.
So, try download DXJF4 from samfirmware.com (and flash with Odin with 513 pit) then uprade to DXJG4 through KIES.
NOTE: If KIES says "Device version's cannot be upgraded". Then you need to change your product code back to "XSO" (Search the forum on how to change product code.... about editing the nv_data.bin file)
My Flash history:
DXJF4-->DXJG4-->XXJPK-->DXJG4

I'm pretty new....
The firmware versions you guys are talking about are I hope, all "software" version and not real hardware chip revisions?
thanks

why dont you just flash your phone with 2.2.1 or 2.3.3(latest).....i know 2.2 is quite unstable FW but 2.2.1 will help a lots......I dont think you need to downgrade the phone back to the stock FW to solve any problem

[Q] How to downgrade I9000 from 2.3.3 to 2.2 stock

Firstly, apologies if this is already posts elsewhere, but I have tried looking for this with no joy (there's aloooot of threads n here lol)
I recently upgraded to the leaked official 2.3.3 using odin (sbl version).
However, I would like to flash with stock software now to get the official upgrade on my Galaxy S via Kies.
Can someone please help or point me to a guide on doing this and where i can download the correct version. I assume its not as straightforward as simply downloading a stock version of Froyo and flashing as I did to upgrade.
My Current phone version is showing as PDA:JVK / PHONE: JVK / CSC:JVK (CPW)
I should point out that this is the first time ive flashed software on my phone, so ideally a step by step guide, if there is one out there
Thanks for any advice you can give

Ok first of all what you need to do is download an older firmware, preferably in 3 files.
Look here: www.samfirmware.com (you need to register, free)
or look here: http://forum.xda-developers.com/showthread.php?t=846913
when you have your selected firmware, you need to download a software called 'Odin', this is what we use to flash firmwares to our devices. Look here for a tutorial http://forum.xda-developers.com/showthread.php?t=723596
when you have 'Odin' and your 'Firmware' you may also need a 'PIT' file, this is explained in the above link. This will re-partition the device and restore the 'bad blocks' and remove any lagfix / altered file-systems ect ect.....
Because you are on Gingerbread at the moment, its possible that you have changed your boot loader, in order to restore this back to Froyo bootloader, i think the firmware you will need is JM1 ( you may need to search here / google for the correct answer)
anyway when the whole process is completed, you should be able to connect to KIES and flash the latest release.
Any problems just write back. im sure we can help get you going !!

I think that JM1 is eclair...
froyo works with the gingerbread bootloaders so you should just be able to flash a froyo rom i THINK.

Hi im also wanting to do the same looking at the samfirmware files would JS8 be ok to flash?

Any froyo ROM is fine as long as it contains the bootloaders as gingerbread ROMs have different ones.
Download your ROM. Check inside the PDA (sometimes code) tar. If you can't see by clicking on it find instructions how to untar it.
There should be a boot.bin and an sbl.bin if there is you're good to go. If not flash another one that has.
You can always reflash with your preferred froyo ROM after the initial flash has downgraded the bootloaders
This link tells you all you need to know about flashing with Odin.

Ok, I tried flashing using the JPY firmware. The process seemed to go okay.
But only getting the 'S' logo for ages then the phone starts ocaasional quick vibrations and screen eventually goes black.
Have tried rebooting ans reseting.
Please help

First boot after a flash does take a long time and you may get the odd little vibration. The screen may go black for a little while. Be patient. If nothing happens after six or seven minutes pull battery try again. If still no good reflash.
You did check repartition in Odin? And use. 512 pit? You need the pit file for a reflash.
Maybe md5 your firmware to check you didn't get a corrupted download.
If you can still get download mode don't worry you will be able to sort it. Most people on xda brick their phones most weeks!

well i reflashed the 2.3.3 leaked and its working for now, will try again tomorrow, getting a bit late.
Was wondering about whether I should try the JM1 instead of JPY. But, on the Sammyfirmware website they only had XW***JP1 which I understand is not for UK/Europe (mine is XX)?
But thanks everyone for your help so far, i may be back on in tears tomorrow

You can use any firmware - they were released with different codes in different regions but if you use a multi CsC like the one in the jpy ROM it doesn't matter because its the csc file that does the regional settings not the PDA file

Hmmm well showing on Samsungs FB page that the ginerbread update has been pulled (by Google)
Guess i'm sticking with the leaked version for now

Sorry to muscle in on this thread but I'm trying to go back from GB 2.3.3 to Froyo 2.2.1. I've flashed JPY with Odin, used repartition, 512 pit and registry patch 1.82 to XEU, phone works fine. Well, Kies then recognises that there is a new firmware (JPY as it happens) and starts the upgrade process, I then get an error message saying that this version can't be updated
Any ideas??

We now have two threads on the same subject but as this was started first I'll continue with this one.
Thanks for the suggestion, I flashed JPU but unable to connect to Kies so flashed the 1 file JPY but still got the same error message with Kies. Maybe I'll try reinstalling Kies and see what happens.

OK, I've reinstalled Kies, changed the product code in the phone with *#272*IMEI# to XEU and now Kies tells me that I have the latest firmware - great bring on the official version of GB.

can anyone give me a link of jpy firmware with bootloader?
the ones from samfirmare.com are WITHOUT bootloader...

Okay, seems that Samsung have finally released Gingerbread.....again. So am gonna make another attempt at downgrading to Froyo so I can get the official Gingerbread update.
However, because of the issues I had with my last attempt, I would like to make sure I am doing it correct.
Current Phone Software
Model: GT-I9000
Firmware Ver: 2.3.3
Baseband Ver: I9000XXJVK
Kernal Ver: 2.3.35.7-I9000XXJVK-CL75655 [email protected] #2
Build Number: GINGERBREAD.XXJVK
I believe the version I installed included the bootloader
The phone was purchased in the UK on T-Mobile but supplied through Carphone Warehouse
Steps:
Downloaded: I9000XXJPY (single file) & 512.pit from Samfirmware (does this contain bootloader? If not, will it cause an issue in updating on Kies?)
Remove sim & memory card
Start phone in Download mode
Plug in USB
Open Odin v1.3
Select .tar file as PDA
Select 512.pit file
Re-Partition - Not Ticked
Auto Reboot & F.Reset Time - Ticked
Click Start
Wait for installation to complete and phone to restart
Hopefully i've provided all the info required, but if not, please post or PM me. If anyone could please check my steps above and let me know if i'm doing this correct or not before I go ahead.
Much appreciated

hi there,
as i know, to run a 2.3.3 rom on SGS , we need to flash a new bootloader right?
but what if i wanna roll back to 2.2.1? do i need to do somthing to re-install a bootloader for 2.2.1?
cuz in most tutor of installing a 2.2.1 rom did mention DO NOT touch the "Phone Bootloader Update" option of odin3
thanks.

I have found a method to downgrade successfully and created a new post with the step by step guide

[Q] Update i9000 from Stock 2.3.3 to Latest Gingerbread

Hi friends,
i was an iPhone user since 2007 but now i bought Samsung Galaxy S GT-i9000, it has "Movistar" logo on its back,
i m completely noob on Android so please guide me.
when i bought my phone it was on 2.0 Eclair then i connected my phone with my laptop with data cable and Samsung Kies.
After connecting:
Samsung KIES showed me Gingerbread Updates
So First KIES updated my phone to 2.2 Froyo
And then it updated it to 2.3.3 Gingerbread.
"""i have read many posts here and as far as i know i think i m on Stock firmware and i updated my phone using Official updates from Samsung KIES and one more thing i want to clear here is before updating my phone my SIM CARD was working perfect no issues and after updating my phone still my SIM CARD is working absolutely fine so i think my phone is fully Unlocked (Please Clarify if i m wrong)"""
So after that long time has been passed i am waiting for Official updates for my phone of Gingerbread 2.3.4 or above but did not find any.
i used 2.3.4 on my friend's phone it works much smoother and faster than 2.3.3 thats why i want to upgrade it unofficially because i cant update it officially.
Can you Please tell me the procedure to update my phone to the latest Gingerbread Stock version unofficially?
Here is what written in "About Phone"
Model Number: GT-I9000
Firmware Version: 2.3.3
Baseband Version: I9000BGJV1
Kernal Version: 2.6.35.7-I9000BGJV5-CL307695 [email protected]#2
Build Number: GINGERBREAD.BGJV5

I updated my sgs to 2.3.4 JVR which works great for me, and I used a guide on the website androidsoul.com to go step by step how to do it with odin, and if you search around a little there are plenty if guides here on xda as well
Sent from my GT-I9000 using XDA App

Which firmware should i go for there are so many
XXJVP = 2.3.4
XXJVR = 2.3.4
XXJVS = 2.3.5
and many more
And what is the difference between firmware with boot loader and firmware without boot loader ?
Sorry for so many questions i m new to Android.

you should go for XXJVS, or for XXJVT, i use a JVT ROM, and its pretty cool.
well, you always have a boot-loader... BUT, you should not flash a boot-loader, because that is one of the rare ways to really "brick" your phone.
the things you need, are odin, the .tar files you want to flash (you should find jvt or jvs here to download, as well as odin)
and just google for flash guide odin, or sth like that, after a few minutes you wil know what to do.
read carefully! and if some points aren't clear for you, don't bother asking.
(The reason why we don't write a full "how-to" is, because it is really done quite often and should not be hard to find)

I have flashed XXJVS Successfully and its working faster and stable than 2.3.3 its amazing. Thank you All for your Support

[Q] Rooting 2.3.3

Howdy,
I got my phone replaced after an issue with a no service state. The phone i have now is a i9000. Refurbished, running 2.3.3 xxjvk. My question is does anyone have any solid advice as to which cf root package to flash? I found 2.4-3.1 on his page. My last phone started off with xxjvt which was easy to root. Im not sure what the difference between them all is. I need some help as I dont feel like bricking another phone as my last one died after flashing back to GB rom from an ICS rom. Thanks.

Look here for CF Root JVK kernel http://forum.xda-developers.com/showpost.php?p=12651359&postcount=6
http://forum.xda-developers.com/showpost.php?p=30067551&postcount=3 , using semaphore will give you CF root plus CWM recovery

Hey
You can Upgrade to 2.3.6 via odin and then root it...heres a guide

Ok. I got 2.3.3 rooted. I have a question about updating my phone tho, KOR is my region code for the phone...Im in Alaska, if 2.3.6 is for KOR I assume that I wont run into any issues? I didn't used to care with my last one, but since it died Im trying to be nicer to this phone as I need it to last more than 6 months.

If theres an update for csc KOR - which my phone is and 2.3.6 includes KOR, why cant I update using kies? I have the firmware pulled already, and want to move to it but was wondering if there was a different way to go about it than odin.

Sure, you can use KIES to upgrade your phone , just connect and try, if failed than you can use ODIN , they are both samsung software, firmware, Odin and KIES downloads can be found on MY Android Collection..link below

I guess Ill just flash it with Odin as Kies says no update available, which is always its response it seems. So thanks.
