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. ;-)

thanks for the info, anyone know the answer to that last question?
you flash the kernel first and then you restore nandroid for the system that ran on that kernel.
Disclaimer: I am not responsible if you brick your phone
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?

So if Nandroid can be used to backup your stock ROM. Then how do you backup your stock kernal, radio, and modem?
Hey everyone, I recently obtained an unlocked Streak from Dell running the 347 baseband, There is sadly no update.zip on my SD as other with this build have said in other threads. So far I have successfully rooted my streak and want to move to Streakdroid 1.9 but have seen multiple threads with people coming from my build getting stuck in bootloops and such trying to move to Streakdroid.
Has anyone had success flashing from 347 to Streakdroid 1.9 or any other versions? If so, what extra steps, if any, were required to flash these ROMs without issues?
Thanks for all the help!
Mine was on 347 and i flashed to Streakdroid without issue.
Only problem i had was making a backup with Nandroid prior to flashing which i outlined in another thread in this section.
Other then that it has been smooth sailing and i have went back and forth testing stuff between both the Stock OS and Streakdroid and have had 0 issues to speak of .

did u do a factory reset or anything before flashing Streakdroid or did u just flash the update.zip and everything worked?
The first time i flashed the ROM i litterally just flashed right over the Original factory one.
After going back and forth messing with stuff i have done a factory reset on both the Original and DJ's .. Not sure i really had to or not but since DJ recommends to do a factory reset after the install i did it the second time i flashed his ROM .
I went back and forth a few times as of today and everything is peachy and am currently on his ROM with the Perfmod Volppt Tabmail in the install.txt file..
Another thing i believe people are making a mistake on possibly is when making the install file from notepad naming it install.txt when infact you just name it install because the txt suffix is on the end already you just dont see it in Windows unless you have file extensions enabled .
So as the title says I want to downgrade back to 2.2 and install simple streak 1.2
Don't think that I can downgrade directly.So how could I go abou3t it?
I wanted sonething nice and not so buggy.how is lobghorn compared to the simplestreak?
Are you aware that version 2.4 of GingerStreak is available and is far more stable than 2.3?
If you want to downgrade, restore a stock ROM first. Doing so replaces the broadband and amss files, as well as ensures that you have a consistent base to work from before putting on SimpleStreak. After that, replace the stock recovery with StreakMod then flash SimpleStreak.
You did search the forums before you asked this I hope?
I was.First thought was to do that.But i didn't quite know if that would replace the amss and the other files i had flashed.Figured i'd double check before attempting anything.
I somehow missed the stability of simplestreak so figured i'd jump to that since streakdroid is pretty much still in beta and some annoying issue or the other always pops up.
With the new StreakDroid comes new baseband and amss files, so you'd have to flash anyway. A stock ROM would put its baseband and amss files on the Streak in place of the ones you used for StreakDroid. But I completely understand the prospect of annoying issues cropping up.
I used the ROM for about a week without a single crash. But then I lost my battery cover and so had to go back to SimpleStreak which has the sensor disabled.
Flashed SS1.2 over 2.4, and did a factory reset. Simple!
Is this possible? The full details are I had my phone stolen, and got a new one with android 4.0.4 on it. I have on my computer a copy of my latest backup of my old cognition gingerbread rom. Can I just use CWM to recover to my old rom, or do i need to first downgrade to a gingerbread rom, and then recover?
Thankyou very much for assistance
Edit: Also, I don't actually want to use the old rom, I just need the contacts it saved, afterwards I'll wipe everything and install a clean ICS mod. In case there's any way of doing this without having to revert
You'll probably need to restore the backup with a version of CWM close to the one the backup was made with, you can often have problems restoring if you're using a CWM version a lot (say 12 mths or more) newer than the one you made the backup with.
So I'd probably go GB/with a rooted GB kernel first, restore the backup & go from there. I mean, it could work first try with an ICS kernel that's running a recent CWM build, but there's a fair chance it won't.
Edit - And be really careful with stock 4.0.4, don't do a wipe while you're running that.
Wow. I just... wow.
Ok, so I did the stupid thing and just tried to restore my old backup without doing proper downgrading first and it ended up soft bricking my machine, couldn't get recovery mode up, but I got into download mode. So I downloaded my country's stock gingerbread rom from samsung's site and flashed it with odin just to see what happens, and somehow my old rom was working again, and I have all my contacts and data. saved everything up to google, upgraded to ICS, import.
Everything went better than expected.
Thanks for the help
Told you Important thing is you managed to fix it yourself without asking silly questions in Q&A. Not many people seem to be able to do that these days.
Well done. I'm glad you got it sorted
Edit -You're welcome
Ok i tried to do my homework first but I am not completely sure for my given situation......
I made a nandroid backup using VRALJB. updated baseband to VRAMC3.
Questions:
can i flash to the nandroid backup i made using VRALJB?
Or will it not work because baseband is different?
What is are my options to flash back to the nandroid made with VRALJB?
Would it be a good (or even possible) option to... flash baseband back to VRALJB .......flash back to that nandroid backup.....flash back to VRAMC3.... then make a new nandroid on the new baseband?
Sorry if these questions are very basic or if i am not grasping simple problems.. trying to get the hang of this. Most of the threads i read are about other phones and i did not see one that even had the same problem.

The libs are not compatible. If you flash back you will be on VRALJB. To be able to use the VRAMC3 you need a C3 compatible rom. Suggestion. Wipe, install a C3 compatible or C3 rom and re-setup your device. Also make sure if you use a C3 rom, update your radios to C3.

I believe the baseband/modems are independent of the ROM. I understand VZW packages them so that they install together but when I updated to Jelly Bean 4.1.2 as an unlocked bootloader user, I was still using the I605VRAL4 baseband/modem before I performed a second flash to install I605VRAC3.
Check out this thread http://forum.xda-developers.com/showthread.php?t=2108510 as you will be presented with the 3 available baseband/modem options to flash. Post 14 of this thread is the OP indicating that he has flashed back and forth between JB and L4 baseband/modems without any negative side affects.

You are correct on the radio being independent of the rom but it all depends on if the OP used the feature in his recovery to back up the radio with his rom. If he backed up the radio then when he uses his nandroid it will put him back on the older radio but he can flash the new one again and will be golden.
OP, if you backed up the radio/modem with your rom in you nandroid the when you use that nandroid to go back you will be on the older radio. If you didnt back up your radio/modem with the rom in the nandroid then you will still be on the newest radio when you go back. Even if you did back up the radio in your nandroid it wont really matter, all you'd have to do is reflash it once you go back ti that nandroid. It isnt really a big deal and won't cause you any issues.
