I am currently running bionix fusion which i know is an eclair rom however i want to flash obsidian, my question was can i flash a froyo rom just as i would any other rom or do i have to install a kernel for 2.2 and when going back to a 2.1 rom do i have to do anything? Sorry if my question is confusing...
Flash it like anything else (depending on the rom), instructions should be in the first post, most flash just like any other rom.
In going from 2.1 to 2.2, you can use CWR to flash the new ROM. The ROMs come with the kernels. But you will want to be sure to follow the install instructions of the ROM you've selected.
Now, if you should decide to go from 2.2 back to 2.1, you will need to flash a 2.1 ROM first. If all if you is a Nandroid recovery without flashing a 2.1 ROM first, you'll have to introduce yourself to ODIN.
so i should be good if say i go from obsidian to bionix as long as i dont do a nandroid backup first thanks for the quick reply by the way

The key word there is *should*.
From what I can tell, if you do a nandroid backup & restore, you want that to be to the same version of the OS. So, you probably don't want to do a backup from a 2.2 ROM and then recover to a 2.1 ROM, or visa-versa. No harm in doing the backup, however. The thing to avoid is the recovery into the wrong ROM.
As long as you flash a ROM that includes the kernel, you *should* be fine. That said, it is possible that something could go wrong, in which case having ODIN around can save you. (It took me several hours to figure out how to get the right drivers to connect my PC to my phone using ODIN. But once I figured that out, flashing JFD on the phone takes only a few minutes. But I don't flash "in the field", only at home - so if something goes wrong, I'm in a position to repair it).
EDIT: I'm not sure why you'd want to go from a 2.2 ROM back to 2.1 if you've already ventured into the custom ROM world. If you're not happy with the Obsidian performance, you might try Onyx or another ROM, like Axura.

Just to summarize, followed by a question of my own.
Correct me if any of this is wrong. These are the points I gathered from reading this thread.
-Ok Nandroid backup is a program which can be used to backup and at a later time restore your stock firmware, i.e. stock 2.1.
-Backing up your current 2.1 ROM is safe, restoring might get you in trouble if you don't have the correct 2.1 kernal to match.
-Any of the popular 2.2 ROMS (Axura, Macnut, Obsidian) all come with the 2.2 kernal coupled.
-Downgrading from a 2.2 ROM, and restoring your Nandroid Backup of 2.1 can get you into trouble, unless you install a 2.1 ROM first which would restore a 2.1 Kernal at the same time.
Now my question is this. How do you backup not only your 2.1 stock ROM, but your stock kernal also? If you decide you don't like custom 2.2 ROMS and want to go back down to your stock 2.1 rom and kernal, how can you avoid having to install another custom 2.1 ROM with kernal, just to be able to put your restore 2.1 back. Confusing question I know, but basically, how can you just go from a custom 2.2 rom/kernal back to your own stock restore of 2.1(ROM and Kernal), will Nandroid backup the kernal also?

Nandroid is the backup/restore component of the ClockworkMod's ROM Manager app. You can use it on any version of the ROM, not only the stock 2.1 version.

Backups are safe. And restoring can get you into trouble if you don't restore to the same version of the OS (more specifically, the kernal, as you've indicated) that you made your backup from.

For this, you have to read the notes for each build. Yes, as a general rule, the latest works are on 2.2 (which means they come with a 2.2 kernal of some kind).

Yes. My trick is that if I flash ROMs, I don't do worry about nandroid. If I'm trying to customize my current ROM, then that's where I do a nandroid. But you have to do what works best for you.

Good question. I've never backed up the kernal. I only flash ones that others have provided. I'll leave that question for people smarter that me to answer. ;-)

you flash the kernel first and then you restore nandroid for the system that ran on that kernel.

EDIT: don't forget the radio/modem as well, it is not being backed up by NANDROID.

Not sure if it was said AND I'm not 100% sure on this but I believe bionix (and a few others) include the kernals in there roms.
and im pretty sure you can just flash over the original fusion you were using and it will also install there kernals.
or you can scope out the bible in the development section to find a kernal.
umm ok so how do you backup your stock kernal, radio and modem?

I had zero problems when rooting and flashing my G1, but now with my Vibrant I am not sure what I did.
A few excellent stickies at the top but I seem to not be making any progress.
Here are the steps I took.
I had a stock Vibrant running 2.1
I downloaded ROM Manager, installed clockwork mod.
Did a backup of my current system ( was I supposed to do a clockwork AND nandroid?)
Downloaded and successfully installed a ROM called Blackhole 1.0
it runs ok but didn't give me the option to switch from 3G to EDGE data, and then I couldn't get internet access at all so i decided to restore my original stock vibrant system.
So I rebooted into recovery, selected restore (my phone won't go into recovery anymore for some reason) and waited, it took a while, then I rebooted (forgot to wipe), but it just got stuck on the Vibrant screen. So I booted into recovery mode again and wiped just user data not cache and rebooted, same thing stuck at Vibrant.
Now i keep hearing about something called ODIN, what I can tell it is some kind of flasher program for ROMS, nobody seems to give any kind of link or anything, is it greymarket or something?
So where am I now? I think the excellent noob guide needs to be updated a bit more.
My phone can get into download mode (whatever it is for i don't know) but it won't get into recovery mode anymore.
Everything you need is here: http://forum.xda-developers.com/showthread.php?t=771111
i think what happened to you is you flashed a 2.2 ROM then tried to revert back to 2.1 without doing the proper downgrading steps i.e. you did not flash a 2.1 kernel first.
but since you can get to download mode.. just flash stock JFD or JI6 through ODIN and you should be good.
good luck
Once you get back to stock don't give up on the 2.2 toms. Try axura or nero. They might have a few minor bugs but its way better then stock 2.1.
Powered by Axura with a dash of Voodoo
I have done the samething as you, coming from a nexus one it seemed easier to flash roms without worrying about downgrading kernels or what not. Recently I was on Nero froyo and flashed to a different rom, and tried to revert back but ended up stuck at the vibrant screen. Think it has something to do with voodoo lag.
Anyways I had to use Odin with the no brick froyo off ebproductions. Ran that and uploaded clockwork, reinstalled voodoo lag fix and was able to nandroid back to my Nero set up. Somewhat of a pain but once you've done it, no need to worry about bricking

Well as long as I can use Odin if I f-up royally like above then I might give it a shot.
Need to read about downgrading kernals or whatever. Might just wait for Cyanogen 6.1
Just so you know, the backup utility in Rom Manager (clockwork) is really just shortcut to a nandroid backup.
The way I have things set up for backups, and this is just for my personal convenience, is as follows...
I have a stock JFD ODIN rom to flash in case anything goes wrong. (A lot of people here will tell you to flash this whenever flashing a new rom. It is safer, and cleaner to do it this way, but not absolutely necessary)
I make a nandroid of my last stable rom (I only keep one at a time cause the files are huge) and keep a backup of that on my PC.
I backup all my apps and a few other things (call logs, bookmarks, sms) through Titanium backup. If you get the pro version, you can load it up after flashing a new rom and have it automatically restore all your apps in one click (system settings can be dangerous to restore when going from rom to rom, so be careful with those.) I also keep a backup of this on my PC.
I will also occasionally backup both of the sd cards to the PC.
Maybe overkill, but you probably wont ever lose anything forever.

Running Odin and my phone is in download mode, about to flash this b**ch.
wish me luck.
I flashed Odin on my phone to revert to stock. Re-Rooted it but now I can't flash Clockworkmod. Please help D:

Hello guys. I currently have Eugene Gingerbread Clone R2 Rom with JL4 Voodoo Lag Fix on my Vibrant.
I want to try other roms for fun. I have some apps and my contacts and stuff backed up and also the entire rom itself. i also have the Stock (Rooted) Backed up as well. My question is how do i go about going back to the "Stock Rooted" safely without using the odin program.

Well, assuming you have ALL of your apps and data and contacts and such backed up with Titanium Pro (make sure, you don't want to lose this stuff!), just reboot into clockwork recovery.
NEXT DISABLE VOODOO OR DIE.
I'm also assuming you made a backup of your "stock rooted rom" with Clockwork Mod Recovery? Now, just reboot into that green clockwork recovery and go to nandroid or backup and restore and click RESTORE.
Yes i have my stock rooted backed up and also my gingerbread rom backed up as well and also some of the important apps and my contacts backed up.
I will give it a try now.
I don't think it worked lol. Screen shows "Searching"
Sweep screen to unlock but screen is black and i cannot do anything.
cannot seem to get back to recovery either
Bob forgot a very important step, flashing a 2.1 kernal...
Best way out is to just flash another Froyo rom through clockwork since you don't want to mess with Odin.
I recommend Axura 2.2.5.7 as well as Nero V3. Go get those and see what you think.
*Edit* just saw your post 1min before mine. You may be using Odin after all.
Ok Thx. Makes sense lol
Nah i only use Rom Manager.
Ok i'm back to my Gingerclone.. I'm going to find Eclair 2.1 kernel, i assume thats the one i need to get and yes i will make sure to disable voodoo before i flash the 2.1 kernel .
Thx.

If you just want to flash other roms, you don't have to return to 2.1 IMO.
Just backup everything (Titanium/Nand/Launcher Pro if used), then clear data and cache in clockwork. After that go to install zip from SD and select the new Rom which should be sitting on your internal 16g memory and let it do it's thing.
Ok well i tried other roms. I tried Nero V3, That one was bad, internet was uber slow and Gps doesn't work.
I tried Axura 2.2.5.7, Worked very well except Gps also does not work.
Right now i'm going to stick with my Gingerbread R2 as for everything works extremely well.
My question:
Is it ok to recover a Nandroid backup that was created on a "Stock Samsung" ROM (meaning right out of the box) while you are currently running a Custom ROM? Or do you have to flash a Stock ROM first?
Same question goes for vice-versa.
Here are the details and why I am asking.
I searched and found an answer, but the poster was not 100% sure.
I have a stock 2.2-based Nandroid backup.
I flashed Biffmod ROM.
I realized I wanted to make a backup of one of my apps from my stock environment.
So, I recovered my stock 2.2 nandroid backup.
Recovery failed in the middle, and "soft-bricked" my phone. << this is why I am asking
I don't know if that is the correct term, but it wouldn't get past vibrant screen and couldn't get into recovery mode.
Incase you're curious, I was able to get into download mode just fine so no actual Bricking here.

im guessing it 'didnt work' because nandoird doesnt back up the kernel i dont think so you'll need to flash a compatible kernel seperatly after for the rom you backed up
You need to odin back to stock when coming back from a CM based (biff mod). I would suggest odining this JK2 rom.

I'm wondering how I can get CWM back on my stock gingerbread fascinate now... I used the speedmod kernel to root, which had CWM built in. Then I replace it with stock GB kernel.. which has 3e recovery.
When I run ROM manager now with gingerbread the fascinate don't come up in the list no more.. there are 2 i9000's, one of those is a MTD... and 2 others. 4 in total.
I have the update.zip file which I downloaded from Rom Manager when I was on Froyo. Will that work? I'm afraid to try.
I've also seen methods of ADB pushing the recovery.bin over the current 3e. I just really not to sure which is the best way to do it, and I've done so much reading now it's got me confused.

I don't want CM, I want to get clockwork recovery on my stock gingerbread.
I'm also in the same Boat. It would be nice to get clockwork recovery installed.
I have successfully rooted Gingerbread, part of the process is to flash the the Speedmod kernel first. With the Speedmod kernel, it has clockwork on it which you can boot into but unfortunately your phone cannot normally boot with that kernel.
I'm loving Gingerbread right now, it is so much smoother then 2.2, there is no way I want to go back to 2.2.

Right there with you - so much better than 2.2 EVEN with lagfix running - was very thankful for ROOT but would love CWM recovery back - very useful tool.
I don't know if it was this thread I made the post, but something I did mention that I did was...
When I used the speedmod kernel to root the phone, I made a nandroid backup. Then I flashed the stock kernel back. I'm assuming if I wanted to restore my phone with the backup I could just flash the speedmod kernel back, restore by backup, then flash the stock kernel back again.
I don't know if clockwork is programmed to backup certain partitions, or if its dynamic, but I'm tempted to try my restore, but at the same time I don't want to go through all the updating agan.
Another thing, I have the 3 ODIN CWM file, the purple, blue, and no color ones you find on here. If you extract those you get a recovery.bin file, and there is no zimage (kernel). If you take one of those clockworkmods with no kernel and overwrite the stock recovery.bin in the phone, shouldn't that work?
I'm still new to android, first time I laid hands on one was this june, I'm still new, but I'm a fast learner too, but I want to figure this one out.

Hey MrManiacNF,
Thanks for the idea, I guess it is a work around for now until we are able to get CWM installed on Gingerbread.
I ended up flashing the speedmod kernal back on, booted into CWM and made a full nandroid backup. Reflashed the stock gingerbread kernal back and booted up as normal.
Yea I do the same thing, I mean you can't make a backup without a pc to flash with, but a backup is better then none.
No love from ROM Manager
Saw ROM Manager had a few updates, but still seeing the limited device selection when trying to create a custom recovery, and still fails with the unsigned zip.
Just wanted to post that if anyone was wondering if recent updates corrected anything, as they have not (at least for me).
I can also confirm, actually no new phones added to the list. I've also tried an app call Root Toolbox Pro. It has options to backup your recovery or flash another. I tried flashing the fascinate-3.0.0.8.zip that I had from Rom Manager from Froyo. No luck, just hung at boot. Had to re-flash stock kernel in odin to fix.
Hey guys,
Wanted to get a sure answer.
Whats the safest way to restore back to the stock firmware fro CM10 (or any rom in general).
There are two answers that i seem to have come across.
Answer 1:
Just download the stock firmware. Extract tar. Load onto PDA, check auto reset the flash reset and then start. Boom done! Everything reverts to stock, modem, firmware, kernel, etc.
Answer 2:
YOU MUST first flash stock kernel. So flash that first via odin then open odin again and flash the rom. If you don't flash the stock kernel first and then just flash the stock firmware, you'll have some issues.
As you can see, both are a bit contradicting. Whats the right method?
You missed one.
Make a nandroid of your stock ROM. then once you're done checking out CM or whatever else, just restore that. A lot less headache.

Yep, nandroid is much much faster. In fact I went to lunch today and restored my CM10 nandroid to show a friend. 10 minutes later I was back to my Samsung ROM. Its much easier than flashing stock, then re-rooting, then loading all your apps and data back on.
I had heard that nandroid restores between stock/CM9/CM10 were causing bugs, or something of the sort.
If it really is working that easily, I might have to give these CM9/CM10 builds a try. I just didn't want to play around with it for a bit and then be forced to set up my stock configuration all again, because I do have a need for a certain level of stability.
Edit: Ah, I was thinking of our Verizon version however. I think it might require an Odin flash back to stock, then you can restore a stock nandroid backup.
While I can't guarantee you won't have problems, I can say that I haven't had any issues while restoring nandroids.
*your experience may differ.
