Dowgrading official firmwares? - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi,
I would just like to ask if it is possible to flash from a newer firmware back to an older one via Odin?
For example: My phone is on official JVS, can I downgrade it back to JVR/JVQ?
Is it possible to flash back from JVR to JVQ? I was thinking because they use the same CSC.
Thanks!

Yes u can downgrade....find firmware at www.samfirmware.com and u can flash any firmware any time.

Follow this and make sure repartition is checked in Odin so you can wipe the phone before installing the fw.
But ya you can go from Froyo to GB and back whenever you want on the SGS...

Thanks for the replies. Anyone else can confirm that downgrading official firmwares is possible? Just want to make 100% sure before I do.
Thanks in advance.

If you do it using Odin there is no problem. did that a few times.

My dear yes it is possible to any firmware at any time

I've upgraded and downgraded ROMs, custom and stock, using clockworkmod recovery.
The first root I did on my phone I used Odin, but the flash came with clockworkmod built in, so never needed to use Odin again.
I feel much more at ease using the recovery mode than through Odin for many reasons, but that's just my opinion, I'm sure it works fine if you follow all the steps.

If your new firmware is Stock firmware(released by samsung), you can flash with Odin(dont select reset partition in odin)
OR you can connect to Kies n update it.
OR Go to setting - about phone - software update, check if update available OTA, if available, you will get notice n update from there(easiest n fastest way)
Hello.
One week ago,I was forced to flash custom ROM,cause something goes wrong and I didn't have backup. However,I want back the stock ROM. Where can I download it? I don't want to install Kies to my laptop,because normally I don't need it. I am able to flash the ROM using CWM.

How to return to stock from Midnote v2.0 ROM?

First off I'd like to say I've read the majority of the stock threads and there was plenty of info there but i couldn't come to a conclusion on how to restore back to my original firmware.
This ROM uses the Abyss kernel and how would i go abouts restoring it?
I had originally a firmware that was directly rootable and i followed a video by cursed4eva to root it.
Please help with any suggestions

Now I revert back to stock ROM 2.3.5 and rooted. If I flash it to N7000DXLA1_N7000OLBKL2_XSE.zip, do I need to root again? Is there any method which can remain rooted after flash to stock ROM 2.3.6?

Hi,
Thanks alot, its work and now I'm on 2.3.6 stock ROM with rooted but when I use mobile odin pro to flash it that time, there isn't an option for me to select the 'Inject CWM Manager'...so now need to install again.
Any idea why don't have that option? Could it be the version of mobile odin?
Thank you.

You can do that using zergrush exploit.. You can follow the instructions given in the stock rom thread by Dr. Ketan.

Hi,
I'm very sorry if asking the noob question here as I'm new to android world.
What do you mean "using zergrush exploit"? To root? If yes then I know what you mean but I already rooted my device and flash the stock ROM 2.3.6 using mobile odin pro.
I just want to know why the my mobile odin pro (2.30)does not have the option called 'Inject CWM Manager'?
Thank you.
See change log
It is removed from Newer version of Mobile Odin pro.

Im on Stock ICS XXLQ2 can i flash stock GB XXLC1 using Odin PC after that i can do Full Wipe/Factory reset etc..

I got the idea i need to flash the Open europe version of stock GB via odin. But the one I found is Wipe version, will this trigger the eMMC bug? (my device is affected)

Afaik the full wipe part will be performed under the gb kernel as that is flashed before the from, so you'll be fine.

Cm kernels will not work with tw based roms, only with aokp/aosp, and vice versa. You'll have to read up on the kernel pages themselves on which rom types they support.
So flash to gb first, perform full wipe, root and install cwm, then you can install custom kernels and roms from there. Never install from ics kernel, only downgrade to gb to be safe.

Downgrading to gb means; directly flashing a gb rom right? Yes, i'm new to all this.

hi everybody
i am sorry for bothering you i just want to ask when using pc odin to downgrade from ics to gb stock rom is enough one pda file or i had to use the other phone and csc file with pit file and repartition, that is my first question.
the second one after flashing the stock gb can stay on stock kernel or it is unsafe.

Most of the rom files split down into three files but If you place the original tar file into pda, odin sorts out the partitions correctly for you.
All stock gb kernels are safe from emmc superbrick bug, safe to perform wipes.

Reverting back to standard ICS.

Hi folks. I have decided to return back to ICS to get the official JB update when it hits in the UK. I was on various Custom JB roms but mainly CM10.1 and now want to try back out the standard JB. Anyways being the sensible chap that I thought I was I done a back up of ICS and that has reinstalled perfect. However not being such a clever chap I forgot I done that back up after updating to 4.0.4 (XXLRK) via Odin when I had my pc and now Kies wont let me update via it. Second problem I have is I no longer have a pc (in my house) because I bought an iMac.
So my question is. Is there a way to get a the standard ICS firmware that should be on an O2 Carphonewarehouse N7000 in the form of a ROM rather than the Odin files somewhere? I still have CWM recovery and Philz 3.99 installed and working.
Thanks in advance.
You can download the firmware you want from samfirmware.com and place it on phone memory. Then use mobile odin to flash the rom.
Do not wipe on stock ics kernels.

Ok I shall look to that idea. Just as another quick question if I do install the firmware via mobile Odin will it change the Kernel or will it keep me on Philz and thus still be safe?
While selecting the rom in mobile odin, it will fill up the partitions. At that time change the kernel manually to philz ics kernel tar.md5 file. That way you will be safe.
Just a thought but i wonder would kies pick up on the kernel and not allow update because of that?
Sent from my GT-I9100 using xda app-developers app
No kies does not pick up kernel. Just PDA, phone and csc. But OTA won't work on other kernels and recoveries.
Had a look on Samfireware but no sign on 4.0.4 for United Kingdom. Am i just being blind?
Sent from my GT-I9100 using xda app-developers app
There is a cpw 4.0.4 in there which is xxlrk. I think that's what you already have.
Just looked one website via iMac and can see it. Not sure but here is a screen shot of my settings and i notice that the firmware seems to be the one listed.
Any other idea why kies not liking this?
Sent from my GT-I9100 using xda app-developers app
This is what my kies says.
Sent from my GT-I9100 using xda app-developers app
Could be because the baseband is incorrect. Open the rom file you downloaded and there will be a modem.bin file. Flash it using mobile odin. Use the modem tab.
Aha i knew it would be someething daft that i was missing. Thanks man.
Can you flash modem via cwm?
Sent from my GT-I9100 using xda app-developers app
I don't know what modem it comes with that's why I asked you to extract from the rom file. If you know then check in this

Go to Here to read and find your answers. If you're still stuck, then ask again. Even though there a few custom roms that can be flashed through Odin, I suggest you avoid using it unless you want to flash stock firmwares.

Hello. Firstly, I'm sorry to say that I don't have much experience as mine came directly from ICS. I can suggest a long roundabout way which is to update your android vers. from GB To JB through Odin procedure first, then just flash philz safe kernel. and then flash any roms u want. Or if you just want stock JB, then u can download stock JB firmware n flash it through odin.
Edit : Go Here And watch the video and read. The link for the kernel provided includes CWM. After Installing CWM, you can directly flash philz safe kernel, reboot to recovery, do a clean wipe and formats (Follow OP of the rom you want to install)
