I write this guide to help you, since I've had problems downgrading from ICS to Gingerbread.
Things you need:
1. Samsung drivers
2. Stock Gingerbread firmware with individual files (including bootloaders) I used JVZ Firmware
3. Odin
Procedure:
1. Install Samsung Mobile Drivers
2. Open Odin
3. Get the phone to the Download Mode by pressing(VolumeDown+Home+Power) buttons and connect the phone to your PC (your phone should be recognized)
4. Select PIT (usually 512)
5. Select BOOTLOADER (APBOOT)
6. Select PDA (CODE)
7. Select PHONE (MODEM)
8. Select CSC (CSC)
9. If 'Re-Partition'is not checked under 'Option', check it.
10. Press the Start button
Note:
If you want to upgrade to a later firmware (eg JW6 - It has only one .tar file),
1. go to the Download Mode again select the file under PDA.
2. DO NOT select the PIT, BOOTLOADER, PHONE, CSC files.
3. DO NOT check 'Re-Partition'.
4. Press the START button.
Hope this post helped you.
Thanks!

Stuck!
Your posting is very timely! Wife's i9000 on CM9 is acting up (wifi loop, random rebooting, and low memory errors). So I want to downgrade to my nandroid back-up with CM 7.1 or at least fresh install CM 7.2. BUT I keep ending up with my back-up on top of CM 9 boot and then getting stuck with a boot loop.
I'm guessing I need to revert to a Gingerbread boot then I can restore the nandroid backup or then upgrade to CM 7.2. I read your posting but I'm not clear where I can get the needed bootloaders. Would be great if I could skip reinstalling stock and just go straight to CM 7 (whatever version) as then I wouldn't have to reunlock the bootloader.
Suggestions? Thanks in advance.
The problem could be the version of CWM... both are v5? they said that nandroid backup of cwm 3 have some issues on cwm 5 (CM9 comes with cwm5).

A nicely written, well laid out, concise guide, nice work

adding the bootloader, imho isn't necessary. personally I never use them, just PDA+MODEM+CSC.
512.PIT is mandatory (yaffs2 -> rfs) , GB bootloader won't do any harm.
In case the update sequence was Froyo -> ICS, downgrade to GB will require GB bootloader.
Hi
ive download a stock odin rom from http://www.sammobile.com
but the file does not contain a PIT file
can some one please post one that i can use
im currently running the remICS rom and want to flash the latest rom for my country that ive download from http://www.sammobile.com/firmware/?page=8&view=4643
thanks
here: Odin + pit
same package as sammobile, w/o zip-password.
has 3 pit files, use pit-512 only!
ive download 2 diffrent stock odim roms but when i flash them i just get boot loops
both of the roms ive downloaded contain the one tar file so i flash it per OP
but i just get reboots so i have to reinstall the ics rom
can some one post a link to a GB rom that has all of pit,bootloader,pds,phone and csc in the one file
thanks

Thank you for the simple guide I downgraded from ICS to JW6 and got stuck in a bootloop, your guide helped me out of that
Thanks man, brilliant guide. Helped me a lot.
As I was busy I couldn't reply to all posts but I am happy this helped you all.
Do we really need a repartition ?
Can we downgrade from ICS to GB without this ?
Most of the forum suggest not to do that as it can lead to hard brick.

Do you have any better option to switch from ext4 to rfs?
Odin + PIT 512 + repartition prepare partition layout for Samsung stock ROM using rfs.

Thanks...
what if i am on a custom ROM like CM9,are the steps the same to going back to stock?
CM9 = ICS = Android 4.0.4

Possible to downgrade for GT-P1000
My phone have
Custom Binary count: No.
Device status: Official.
In the setting>about device>status>device status:Normal. Now, I'm getting on 4.1.2 from MJ5 4.3. I used the followings
1. flash the respective official 4.1.2 firmware from sammobile.com. after finish flashing , go to recovery mode and wipe data.
2. flash Philz recovery via Odin.
3. install updated 4.1.2 modem (XXDME4 / DXDMF1 / DDMG1) from http://forum.xda-developers.com/showthread.php?t=2044937 via CWM (at this step you should get IMEI back.)
4. root the device with CF-auto root.(CF-Auto-Root-t03g-t03gxx-gtn7100.tar)
5. install Triangle away to reset flash counter.
6. full unroot super SU
7. wipe all data/factory reset .
Check the device status in setting. And then go to download mode to check again.
I'm not sure is this steps working on every Galaxy note 2 N7100. But actually I've been downgraded to 4.1.2 and I can get OTA also (already checked).
I decided to downgrade my N7100 because most of the custom roms use high RAM usage.
When at the firmware upgrade fail status,
1. Just flash "Philz recovery" via Odin.
2. After finished, Long press Vol up + Home + Power button to get into recovery mode.
3. Choose Wipe data/factory reset and "CLEAN TO IN STALL NEW ROM"
All of this step finished, Go to download mode "Vol down + Home + Power button" and flash the firmware (4.3 or 4.1.2 again).
NOTICE.
Dear all,
The latest 4.3 official firmware (MK4 or later ) has KNOX enabled bootloader and can't be downgrade. So, don't try to downgrade If your bootloader is KNOX enabled.

Remove KNOX bootloader to return to stock - using Dr. Ketan Method
Hi Guys,
I just want you opinion before i do this step. Hence asking
KNOX enabled boot loader has messed up my idea of return to Stock either via KIES or via ODIN.
I flashed the official Indian 4.3 ROM on my EU model NOTE 2 over the leaked ROM with MJ5 and it failed. I couldn't recover the phone with KIES either.
KIES will say that firmware update / emergency recovery has encounterd an error.
ODIN says FAIL and "Device Unsupported" appears in Download screen.
Shall i try Dr. Ketan's KNOX bootloader removal method to get my mobile back ? ( http://forum.xda-developers.com/showthread.php?t=2500823 )
Can i then flash the original firmware N7100XXDMF1 on my Note 2 (EU version) ?
Would appreciate if you guys could help me on this.
I can still access the download mode with KNOX boot loader.
Thanks

I am using Indian 4.3 rom on my EU device (N7100 Note 2)
It use Know enabled Bootloader.
* When I try to flash MJ5 bootloader with Odin, it failed. (incorrect version)
* When I try to flash EU 4.1.2 rom with Odin, it failed. (incorrect version)
Is there a way to downgrade to EU 4.1.2 rom? I guess NO

Same problem here
I flashed the 4.3 indian version. After 40 minutes it doesn't finished and my laptop battery is discharged. When i switch on the phone, it shows me the message error "firmware upgrade encountered".
Kies doesn't work.
I'm not able to enter in the recovery mode. I'm able to enter in the download mode. If i try to flash the rom again with odin, it shows me this error:
Any suggestion? thanks
flash recovery thru odin then maybe restore a nand backup or flash the new rom via cwm
So is there some other here already tried this step and got success??? please post location and if your from custom rom or from official rom? thanks

I'm able to flash the recovery thru odin, just do it and now i'm able to boot in recovery mode.
But i'm not able to flash the new rom via cwm because i'm not able to mount the sd card (it works only as usb storage, not as sd card mode and so i'm not able to upload the rom file on it).
I can find a solution for this, but i'm not sure it will work because now i have the knox firmware (warranty bit 1) and it isn't downgradable. Am i right?
thanks

I don't recall the exact steps, but I flashed my old 4.1.2 stock rom through philz recovery then ran the efs restore through dr. Ketans multi tool. Before the efs restore I would get boot loops at the Samsung logo.

Put the phone into download mode
Connect to PC USB
Check ODIN has the COM port highlighted at the top
Add the stock ROM to AP in ODIN
When it is ready, press Start
When ODIN is finished flashing, it will reboot your phone into your new stock ROM
Stock ROM running on your phone after that will be able to take OTA updates (As long as you don't root / custom recovery)
If you want root and custom recovery again, just do the same as you did last time, and each time you want to update, just follow the above, that's how I update
