[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] What firmware use to upgrade from 2.2 to 2.2.1

Hello,
I've a Galaxy-S (was from T-Mobile Uk, but I unlocked it, debranded it and so on), it used to be 2.1, so back in november I updated to 2.2 using the Kies trick (changing the area code and so on). Now I'm finding myself *not-so-happy* about many bugs that are around (sometimes apps just crash... etc..). I'd like to go to 2.2.1 if this would help. But Kies doesn't even show an available update, so I was thinking of flashing one with Odin. Which one do you recommend?
My firmware is XXJPP. I don't remeber how to get other info/codes, so tell me how if you need them.
Also, I'm ready to wipe everything, but I'd avoid it. So tell me how.
Thanks.

JPY or WJS8 in UK with CPW csc .
Build your own in the rom kitchen .

I suggest you the JS8 ROM. Is the last froyo 2.2.1 european firmware. You can use the JS8 rome in the romkitchen to customize your fw as you want

Odin for flashing Kies for orugnal upgrade

Is JS8 an official upgrade from JPY(2.2.1)? For the UK aswell????
Or is it just a general European(including UK) update?
I'm on JPY right now. Upgraded officially from JPO(2.2) in the UK.
Do you think it is better to flash JS8 firmware?
(I have tried 2.3.3 JVK but I would rather wait for the official gingerbread update)

JPY is still the most current firmware for UK. I'm in Australia and have been using it since release. Docs version of course.
JS8 is Nordic I think.

For stock go to samfirware.com, sign up, download Odin and jpy 2.2.1 (for UK). Install with Odin without repartition ticked and you should still have your apps/data.
Site has all the files and instructions you need. Just make sure you have download mode.
2.2.1 is miles better than 2.2. You'll wonder why you waited so long.

The networks do not upgrade all the incremental updates JPY last one in general use and none have bothered to push out the later upgrades preferring to wait for the official release of 2.3 .
Either JPY or WJS8 will work well on UK phones .

I tried both the kitchen and the: stock Rome. Even if the kitchen seems so clever and you don't need Odin in order to upgrade, I ended up with a 2.2.1 Tom that didn't have the market app, and other basic ones. Plus the media scanner was crashing every 10 seconds. Another one started up in Chinese and kept crashing various system apps. That's to say that it is not the best choice for stability. Instead I went to samfirmware got 2.3.2 and it is stable, clean and fast. Using Odin is easy in the end so I recommend this if you want a fully functional phone. And gingerbread is so faaaast

That's to say that it is not the best choice for stability.
You are doing something wrong then as its the safest and most problem free method .

I have 3uk sgs and immediately went for odin for all my flash updates.
First thing is to check u have three button combo working. Just pull the battery to get out of that mode.
I'd go straight to gingerbread JPK. And with the few, clockworkmod zips you can add battery percentage and a few other nice things that aren't included.
I haven't looked back as jpk is such a great rom - memory management is sorted so no need for autokillet or taskmanagers.

[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] Stock firmware that works with Kies?

I want to restore my SGS to stock firmware, so it works with Kies etc, as if I've not installed custom roms on it.
Which is the best route to go with this (e.g. which firmware version), preferably Froyo or Eclair.
Thanks!

Use Odin and install one of the Stock, or stock deodexed ROMs. Or if you want to revert back to original Vodafone ROM then check http://www.samfirmware.com to see if they have it. All stock firmware should work with Kies. Out of curiosity, why do you need Kies ? I never use it.

You can use Check Fus Downloader to download lots of stock roms. It depends on what country and carrier.

JPY did the trick, was correctly recognised by Kies and offered me the Gingerbread upgrade

The reason I wanted to install an earlier firmware was just to ensure the phone was correctly identified by Kies, and the Kies firmware update process would complete ok.
I'm probably going to sell the phone, hence need to make sure it's in "factory" working order.

Well from factory, all eu uk sgs phones will be shipping with jvo...

My phone was running a custom rom yesterday. Flashed froyo jpy when I had issues yesterday. connected it to kies and it gave me gingerbread jvo. No spoofs. It just worked. Now back on simply honey but at least I have a route out now!

How about an asian ROM that works with Kies Firmware Update?
I Flashed back to DXJF4 to try to update my firmware to at least DXJPA via Kies but the Update button is greyed out.

[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
