Hey guys, put quick and simply, I can't restore a nandroid backup of a gingerbread rom from september 2010. I've been going back and forth between those builds for months restoring and booting fine, but ever sine i've installed an ICS rom (ASUS stock) I can't restore and boot into my gingerbread ROM... So ultimately my question is ,buy flashing ICS does something change which messes up my Gingerbread?
CWM does not restore the kernel. So if going back to HC via a restore you still have an ICS kernel.
After the restore is done flash the HC ROM you were using to get the correct kernel back in place.

i have a nandroid of ji6. do i just apply that and flash a ji6 kernal? can someone link me to one if so? if not, can someone explain how to do it? thanks.
I believe you have to ODIN the official JI6 release (you can find it in the dev forum). Then you have to root, install ROM Manager, and nandroid your way back to where you were.
The key is to Odin a Rom, any Rom, that has the JI6 kernel.
Odin JI6 and then nandroid.
Nandroid doesn't install the kernel, so you would end up with a "brick" if you tried to nandroid on a 2.2 rom.
thanks guys! loving obsidian so far, but i think i need the signal strength boost from ji6.
Nope, I was on Obsidian and just flashed straight back to Bionic Fusion through clockworkmod recovery (straight, not through ROM Manager), and then Core kernel on top of that. I'm running perfect apart from slow market downloads (mostly my fault I think--accidentally deleted some system apparently and then restored; downloads work, but fussy)

that's because bionix flashes the kernal along with the rom. nandroid doesn't. that is why i asked if i could just flash the ji6 kernel after restoring my nandroid.
ATTN: Don't give advice if you don't know what you're talking about.
On to the post:
You can feel free to nandroid or flash to/from anything. However, if your Obsidian install is like many other peoples, you probably can't do crap in recovery. In that case, you need to Odin. However, if your recovery does work, just flash the rom and the kernel (or just the rom, if the kernel is included)
OK ill give it a shot if I decide I don't like obsidian. Thanks.

By can't do crap do you mean can't flash or can't access clockwork mod? (I can boot into clockworkmod just fine)

Ah, sorry. I thought the issue was whether you have to ODIN back to stock in order to roll back from Froyo.
For me the safest was to ODIN JFD, then flash JI6.
phone has been working crappy and i want to revert back to ics for the time being until google works it out. what's the easiest way to do so. can i just put a zip file and apply it through recovery like i did to update to ics?

Yep. via your file manager try the recovery trick
I've already seen a thread about that here but I can't find it quickly now. Anyway, you will need cwm recovery to revert back to Gingerbread from ICS because stock recovery won't allow you to do so.
EDIT : Here is the thread [Q] Downgrading Nexus S from ICS to Gingerbread.
EDIT 2 : If your phone is not unlocked you will need this to proceed... It looks like a pretty good and comprehensive tutorial to me Downgrade Nexus S from 4.0.3 To 2.3.6
You wanna go back to stock? Go on Peter Alfonso's web site. He has a stock rooted gwk74 zip you can just flash through cwm with a wipe.

yeah, just wipe then flash gb rom
So i flashed ICS on my note and found it quite buggy especially since i cant see whos calling me. i wanna go back to the stable Gingerbread but when i flash it hangs at flashing modem. Can someone advise me what am i missing. i managed to recover my device from brick using ODIN and im back on ICS.

Go into recovery.
Flash a GB kernel (franco in my case)
reboot into recovery (do not boot into android: menu: Advanced->reboot recovery)
flash GB rom, of restore backup. (backup in my case)
reboot
Worked for me.
I was on ICS. went back to GB using the above method.
Ah kernel first. Okay illl give it a shot thanks

Yes, because then you will have a GB compatible Recovery.

[*]flash GB rom, of restore backup. (backup in my case)

Thank you.

Either stock ROM or cooked. If you use stock, you will have to root again, so make sure you use a stock rom which can actually be rooted or you'll have to flash another. I think it's just easiest to go straight to a cooked ROM.

You cannot flash a stock rom through Recovery, you'll need Odin to flash a Stock ROM.
Hey guys i think there is something wrong with my phone because every time i do nandroid backup and then restore from it i always end up in a bootloop, no matter what rom or kernel i am on... it wasnt happening when i was on gingerbread roms like cm7, it started when i switched to ics rom (cm9) and since then every time i restore from nandroid, the phone ends up in a bootloop... can you guys please help me? If you dont see my sig - heres my specs: Galaxy S I9000 phone running on Slim 3.1 on Icy Glitch B6 kernel. The initial base ROM is KG3 2.3.3 Gingerbread - from there i went to cm7 then slim.
PS: yes ive tried completely wiping everything via Odin but still didnt fix the problem.
Are you restoring the backup using the same rom, cwm version that you used when you ran the backup?
eg if you took a backup of stock jvu, then upgraded to ics, you would need to flash stock jvu, then restore
Sent using TCP/IP
that's right. if you backup in jvu, you can restore only in jvu roms. If you try to restore a JVU backup on another rom, it will bootloop

The only time I have been able to restore successfully is from CM7 to another version of CM7. So flash Slim again, and then restore the nandroid backup.

What the ....?
If you do a complete Android backup, you can restore a jvu rom after flashing jw4. You cannot restore a jvu rom if you flashed a cm or miui from, but always a gingerbread on gingerbread from. Always a ics after flashing a ics rom. I was on icssgs 4.2 and flashed cm9. Restored icssgs without problems. And the same with slim ics....

Really? Because this time I tried going from cm9 back to my slim 3.3 and it bootlooped. I had to wipe data and reflash the slim ROM :/

Hi folks!
As the title suggests, I want out from JellyBean and back to MIUI Pickachu Edition 2.xz
I think the latest 2nd boot builds have the GB kernel since I see 4 Vsel levels, so should I flash the froyo kernel?
If so, what should be the order of flashing ROM -> Kernel or other way round?
Also, I have a nandroid backup of when I had MIUI. What steps do I have to follow to restore it, i.e, do I have to flash the ROM (and/or kernel since I was on froyo kernel when the backup was taken) to restore nandroid?
I read a lot about the fuss of latest nightlies changing /system and /data to ext4, but in my case they are ext3, so I guess I should be alright?
Reason for going back is LAG! the immense amount of time to open stuff. I tried loving it, but its just too slow to the point I feel like its running Windows 8 on Intel 8086.
Please post all questions in Q&A. Thread moved there.
Hi!
My friend was in same situation and he went ahead and tried to flash MIUI Pickachu edition, but his process got stuck and now his Defy won't boot.
Hes now flashing stock Froyo sbf.
Thats the reason why I need to know instructions to get back to MIUI without going through sbf flashing.
Any help gladly appreciated!

You need to flash a Froyo SBF. For some reasons going back to 2.3 always ends in a cache error, flashing 2.6 kernel, nandroid, fullwhipe etc. doesnt work

R U on Froyo or GB? if Froyo try to flash fixed sbf I will attached if needed.
Just flashing froyo kernel was ok for the 2nd boot builds upto 9 nov builds.
From 9th nov builds the cm10 rom formats our defy to ext4 file system, so in order to downgrade we need to flash the sbf.

My friend, thats what I have said, in my OP,
I have checked using mount command from rooted shell and I can confirm that my /data and /system are STILL in ext3 even though some say that the latest nightlies change the fs while formatting.
Try restoring your backup, you may succeed, otherwise you need to start all over again, with the sbf. I find it better to start all over anyway, no matter, what rom we are talking about. Those installed over a freshly flashed sbf proved to be snappier and absolutely bugfree - at least for me.
Simply try to restore your backup. I tried many roms so far, aslo the newest by Quarx and Epsylon and i always worked for me to install a new rom/zip/ withour anything further. Never installed a sbf.
Was quite late in posting a reply but I did end up flashing Stock Defy 2.2.2 SEA sbf.
I did flash successfully MIUI (Pikachu edition) but it was a bit off, so took a backup and flashed sbf.
Have been on stock ever since (been kinda busy).
