[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] Flash Back to Samsung Firmware

Euro Tab
Just installed the Gingerbread official firmware from forums but Kies will still not show current firmware, when I installed a ROM before it changed the format.
Is there a way to put the Tab back to stock firmware so that it works with Kies again now that we have an official release rather than using Odin
Thanks in advance

English in the English forums please.....Whatever THAT language is it does not belong here.

Anybody
Still no answer is this not possible?
Just want to put tab back to out of the box state by re-flashing the tab using Kies.
I have done it using Odin and now have gingerbread but want it to sync with Kies for downloads again.

Well I did it.
I flashed Rotohammer v4 and used bootloader patch to see if there is a protected one. But as far as I know GB doesn't have protected bootloaders.
Then I flashed the P1000XWJJ4 firmware. Works for me. If this doesn't work try P1000XXJK5.
After that KIES recognizes your tab and offers you updates again.

Gtab DOES have protected boot loaders... They are generally loaded on from those official updates you seem to like... Be careful if you decide to put custom firmware on after reflashing stock as you might find you have a brick...

Can you clarify a bit more as I have flashed the official Gingerbread from Italy onto the device and it working fine apart from Kies does not show any firmware info.
Do I just need to flash the stock UK firmware including bootloaders when it is made avalible and then it should work again?
Tab states the following version info:
Firmware 2.3.3
Baseband P1000XXJPZ
Kernal 2.6.35.7 [email protected] #2
Build GINGERBREAD-XXJQ1

OK just tested again in Kies and it updated Kies to version 2
It now states:
This verision of the device can not be updated
Current firmware version: PDA:JQ1 / PHONE:JPZ / CSC:JQ1 (XEU)
Hopefully this means that when the UK update is released it will allow a force flash or something.

[Q] [i9000] restoring to Stock - but which ROM?

Hi All,
I have a Galaxy S I9000 that I purchased from Optus (Australia) that I have been flashing with different ROMs quite happily. Unfortunately in my excitement I did not take note of the original versions.
I had a nightly build of CM7 on it but now that Samsung Australia have released Gingerbread I wanted to do a stock upgrade (with Kies) to try it out.
So I reverted to a stock 2.2 I got from the ezRom guide (can't post the link)
BUT, kies says that it is not updateable.
So then I tried to revert to a ROM that is supposedly an Optus one. I have flashed it to (According to KIES):
PDA:JP5 / PHONE:JP3 / CSC:JP4 (NEE)
Or from the phone:
PDA: I9000DTJP5
PHONE: I9000DTJP3
CSC: I9000XSAJP4
Build info: 2010.11
But Kies still says "This version of the device cannot be updated."
Is it because of the CWM bootloader (v2.3?)?
Any suggestions / ideas?
Many thanks in advance

Have you tried using ODIN for flashing?

Good suggestion, and it flashed OK and works OK, but, KIES still says it cannot be updated.
Should I flash the bootloader? It is CWM.
I wonder if KIES looks for the bootloader.

Kies is a huge pile of dung. Why bother messing with the bootloader when you've already flashed what you wanted?

Several Reasons:
1) I want to see what Samsung's "Official" version of Gingerbread is like.
2) CM7 bluetooth pairing is broken. I am totally over having to go through the pairing process every damn time I get in my car.
3) I have to go back at least to 2.2 at some point as I have lost access to my External Flash card.

You should be able to grab the stock fimware from samfirmware.com and flash it with odin, no?

Hi,
I have successfully just done what you are trying to accomplish. I don't have the links to these files anymore but if you can't find them I'd be happy to make them available for you.
Firstly flash GT-I9000_FROYO_FULL_PDA.tar as it has a boot loader.
Secondly flash GT_I9000_DTJP5_DTJP3_XSAJP4 which is the original stock.

this looks like the link for the froyo full PDA tar: http://www.multiupload.com/3FFWC68UMC
so does this work? I want to get back to stock Optus and similarly didn't take note of any original versions or do any nandroid backups. idiot!

[Q] Help me please. 2.2

Okey, first of all, I'm a complete noob when it comes to this, so I need some help.
After long browsing I was able to root my Samsung Galaxy.
Now I want to update my Galaxy from 2.2 to Gingerbread.
Since I rooted my Galaxy it won't connect to Kies anymore, so I guess Kies won't work.
I have an Samsung Galaxy S I9000,
FROXO.XWJPA,
Kernel Version 2.6.32.9
Is it possible to update, if yes, how?
Thanks

anyone? :l

Download a FW from Samfirmware, the latest is I9000XXJVR (Its 2.3.4), then via Odin you flash a 3 file's, its CODE, MODEM and CSC, and pit file and tick re-partition

Xooley,
I'm new on the forums so cant post any links but if you search for "how to use Odin" then it's really not that difficult.
The biggest decision you have is whether to stick with a "stock" copy of firmware i.e released by the manufacturer or install one of the modded versions from the hard working developers on XDA.
if you have a rooted phone then this wouldn't normally prevent KIES from working, so it might be that your carrier (orange?) hasn't release a Gingerbread version yet.
You can get most stock roms from samfirmwares as stated above. If you've never installed a rom before, make sure you read about it (checked youtube) to see if there are any problems with the one that you have chosen.
best of luck
