I've flashed a few roms now (masters stock rooted voodoo versions of nexus s firmware) and every time I do the boot logo just keeps on going until I do a battery pull and reboot, and then it's ok.
It's not a problem, I just wondered why this happens??
did you wipe dalvik, factory settings, cache?
did you change the kernel?

No. These roms don't wipe anything and I don't want to lose my stuff. I don't think you are meant to wipe with them either.

I was asking if YOU did wipe them because if you're going from one ROM to the other ROM you are supposed to wipe.
You lose your settings and apps. Back them up using Titanium Backup (Or any other related app).
Or.. better yet, just perform a nandroid backup. After that, wipe those 3 and reboot. See if the problem is resolved, if it is then you already know. If not then nandroid restore.
If you're going from one ROM to a completely different ROM made by someone else, you have to wipe data/factory settings!
If you're flashing an updated version of the current rom you're using, wipe cache/dalvik-cache.
If you're flashing different roms every other day, go buy Titanium Backup to backup your apps/settings.
And uh what ROM are u flashing where "you're not meant to wipe"

I am new to this so I'm still getting my head around it.
From stock I went to the rooted voodoo version of this - http://forum.xda-developers.com/showthread.php?t=971690.
From there I went to the stock rooted version of this - http://forum.xda-developers.com/showthread.php?t=979851
In both cases it says:
Rom Information:
Does it wipe: No
Does it flash the radio: Yes
So since they don't wipe, I assumed I shouldn't wipe anything, but it looks like I was wrong. From your post it looks like I should have wiped the cache and dalvik cache. I know how to do this in CW but I've never done it and my roms are working fine.
So next time master releases an update I gather I should wipe cache and dalvik cache yeah?
Also, when I do this will it remove any of my settings or apps?
Hope you can answer these questions, and thanks for advice so far.
<<edit>>
Just did a bit of googling and it looks like you don't lose settings when you wipe dalvik cache and cache, so what does actually get removed.
There is a thread stickied in development called ref roms themes and kernels. It gives step by step directions on how to flash all three including what should be wiped. Check it out

because its saying that the ROM doesn't wipe. Some ROMs are built in a way so that it automatically wipes your phone to ensure best performance. The creator is just saying that it doesn't do that BUT you need to wipe. The keyword does and need are two different things. The basic concept between going from 1 ROM to another (unless its the same ROM series) requires a wipe in all three: dalvik, cache, factory. If you're going from the same ROM to a newer version and encounter bugs, its best if you wipe.
I'm a more advanced user when it comes to Android since the first Android phone. I know what I'm talking about. When you go from stock ROM to another, its going to have bugs if you don't wipe.
If you're using Axura 1.1.1.0 and its fine, and he releases a new version. You can flash without wiping (but you can wipe cache & dalvik to be safe; none of your settings will be wiped). Wiping factory settings is the only one that will wipe your settings / apps.
If you're going to be a flasher, its best if you purchase Titanium Backup Pro (or MyBackup.. but I highly recommend Titanium Backup). Use this program and it will save all of your apps + settings to them. Just don't use it to save SYSTEM apps/files because it will cause FCs.
Dalvik Cache / Cache.. its nothing you need to know in particular. It's just removing cache that your phone set up to increase speeds. It just wipes them and gets the Android system to re-establish them. So no caches from the previous ROM will carry over onto the new one.

That is a very helpful post and clears a lot up. Many thanks. Looks like I had better do it again and do it right this time.
I've got titanium backup. Bought it after I rooted, but never restored with it yet. Also, thanks for the info about no saving system files with it, as I currently do have it setup to backup all user apps and system data, so I will have to change that. I gather I should just change it to all user apps??

Backup all user apps is the one you want to do. You can backup bookmarks using Google sync or a app known as BookmarkSB
If you have system apps backed up, delete all backups using batch and reapply user app backup

Thanks for your help. I reflashed the rom and I did it properly this time. Had a bit of a problem with TB restore as I'm a noob but Joel from TB answered an email I sent him very quickly and I got it sorted (thanks joel).
How long does it take to flash a rom once you get good at it? Took me a while tonight because of mistakes.

I can usually get from booting into recovery to having a usable device with most everything set up in about...10 minutes? Assuming I already downloaded the ROM lol sometimes those mirrors are slooooooow.

Searched and didn't find this specific question or anything close - so I'll post
I've been flashing roms a lot now that I've got the hang of it, but I think I was creating a problem for myself with titanium backup, which I think I've maybe now solved, but I'm not absolutely sure.
On the last couple of nighlies of CM that I've flashed I've been getting unfixable FC of the phone app (rom manager fix permissions didn't fix it and neither did wiping dalvik cache).
So I flashed ns-collab and I like it, but today I got the same FC problems and had to restore my nandroid to get the phone working (I was at work).
NS-collab is meant to be stable so I was starting to think that it's not the roms that are at fault but something I'm doing, and I had a feeling it was what I do with TB. So here is exactly what I do when I flash a new rom.
____________________________
I have TB set to "backup all user apps". That's it - no system data.
Before flashing the rom (even if it's just an update) I clear data, cache, and dalvik cache.
When I've got the new rom flashed I do not allow google backup to restore my stuff as I want it done with TB.
In TB restore I run "Restore all apps with data". When I do this I select the app+data checkbox in TB before clicking "Run the batch operation".
___________________________
So, I had a look at the apps that get restored when I run TB "Restore all apps with data", and I noticed there is quite a lot of android stuff in there like the dialler and lots of other services that are part of the android os and don't need restored with TB really.
I've just flashed the updated version of ns-collab and I removed all these android services from the TB restore before I ran it so I'll see if any problems crop up now.
But my question is, was I causing the phone to be unstable by allowing these android services to be restored by TB. Remember I did not select to restore system data, but I am wondering if system data was restored anyway because there were android apps in the list and I had the app+data option selected.
Hope the above isn't confusing and any advice will be appreciated.
Lot of information but I say you found your problem yourself.
I have not had issues in the past restoring: bookmarks, contacts/calls storage, SMS/MMS/APN Dialer storage, SMS/MMS PREFS etc.
I do think you are giving yourself a little extra work than needed. It is not necessary to do a data wipe before updating a ROM, wiping cache and dalvik cache should be sufficient and a lot of people don't even do that. Of course a good clean wipe every now and then is good and gives you that warm fuzzy feeling inside like after you change the oil in your car
In general, I do not recommend a full batch restore like restore all apps and data. I find when restoring with TB it is a good time to clean up and only restore the apps your really want back on your phone. I also do a batch restore, de-select all and just go down the list and pick out the stuff I HAVE to have.

I think you are right about me giving myself work. Because I'm still a noob I'm still over cautious I think.
Maybe I'll try doing it your way. Sounds sensible.
Anybody know definitively whether me restoring everything via all apps and data would have contributed to the FCs I have been getting?

Did you try fixing permissions? I only use the batch for Backup all user apps.
Backing up bookmarks.. I use BookmarkSB and SMS (i know theres a app for that) but i use GVoice so i dont need it
I've never had a problem restoring user apps with data. Instead of restoring all, choose restore missing user apps with data or something like that.
Although, I've had problems restoring SMS and certain data for system apps on the NS. Can't figure out why it doesn't work but whatever.

I would suggest you install app2sd & move your application to the sd-card. Each time you flash a new rom just wipe the /cache, dalvik-cache and battery stats. This is all you would ever require.
Thanks for all the replies. Quite a few suggestions there which I will try out.
Didn't have any FC problems at all at work today, so I'm hoping my more cautious restore last night might have done the trick.

Yeah FCs happen when you backup system apps / bookmarks etc. It could interfere
Hi,
I can't find an answer to this question, maybe I don't know what to search for.
I have a new Nexus S that is rooted with CM7.0.2 and Clockworkmod recover installed already, as well as ROMManager (I've already had it d/l 7.0.3)
I see that CM7.0.3 is available, and I read in the comments that a wipe and a dalvik wipe are recommended.
I'm up to date on my backups with TB and Mybackup pro, but I just wanted to know if these updates will reset the phone to an initial state or not.
thanks

It does not bother me but it will bother others, so I'll tell you. You should have posted this in q&a. Easy mistake to make though, but I bet you get some grief for it
Anyway, you need to wipe data, cache, and dalvik cache before you flash, but this will not delete all your personal stuff on your sd partition. You will still have all your folders containing pictures, music, etc. It will not be like going back to when you bought the phone. Nothing like it. And if you have a TB backup then you're cooking with gas. Just tell TB to restore all missing apps or restore all user apps. Do not select the option to restore system data. That brings system info' over from one rom to another and can cause problems.
Thank you.
My bad. I had the General section open in another tab and I just overlooked where I posted.
Please go easy
Cheers.
you wont get any strife off me anyway
Does that help. You know what you are doing with this now?
If you are on 7.0.2 then you should be fine going to 7.0.3. But don't go from any other build of cm7 to 7.0.3. I don't remember the details, but apparently it causes problems.
Moved to Q&A.
Hi,
I backed up my phone with Titanium and after updating to 4.0.3 tried to restore data only, from that moment - messaging force closing.
what can I do ?
thanks
Clear any messaging related data, reboot, and then see what happens.
Thanks but it's the same - the app loads and than crashes immediately,
Can I re-download the apk somewhere ?
I know it's core element - but maybe it can be extracted from the whole update ?
Well just to reiterate make sure you wipe all relevant system apps in titanium as that should do it (just want to be sure ).
But you could reflash the rom again, or part of the rom.
And yes you could pull the apps from the rom and install them without reflashing (though you will have to use titanium to make it a system app probably).
Oh yeah you could try wiping the dalvik cache.
tried wiping the dalvik cache did not help. how can I flash only the messaging app ?

Well I haven't done such a thing for a while but when I did a similar thing I did it like this:
1. Get full rom zip
2. Open zip with 7-Zip (or similar program).
3. Delete anything you don't want to be flashed again (I guess in your case nearly everything)
4. Flash
Note: I said open the zip, not extract it.
Can't guarantee this will work though I would personally just do a full wipe, flash the whole rom again, and be careful what you restore (i.e. don't restore system data).
Never use Ti to restore data after changing roms. It's the first rule of Flash Club.
I am running Eagles Blood CM9. If I switch over to EGB AOSP will the "Backup and Reset" --> "Backup my data" and "Automatic Restore" features that are included in CM9 be available in AOSP?
I guess I am wondering if I have to reinstall apps manually or not?
Thanks,

When switching ROMs like that you should: ** In CWM
(You must do this so no bugs are created.)
1. Wipe data
2. Wipe cache and dalvik cache
3. Install rom
4. Install latest GApps(4/29/12)
This will wipe all your apps, which you will have to reinstall by going to the Play Store>Menu>My apps>swipe over, and there it will have all your apps. You'll have to do that if the play store doesn't automatically start downloading them. But, if you use titanium backup, you can try that, but I've read that it causes problems.
Lastly, you can dirty flash(don't wipe data, only cache and dalvik cache), but this will most likely cause bugs that aren't because of the rom. So, from coming from the Eaglsblood ICS to their AOSP ics build, do the first instructions to be safe.

I have had no problems with Titanium Backup. The only thing is that you must make sure to backup apps right before you flash.
Hi All,
I'm looking to change my rom from Oxygen to anything at this point. The complete lack of support has me disappointed but there are a few things that Oxygen seems to be missing too. I want to change and upgrade my rom but ideally I'd like to do without completely wiping everything if possible.
Any Suggestion?
Thanks

The short answer: you can't. You must perform a full wipe (system, data, cache, dalvik cache) when changing ROMs, please note that wiping data doesn't touch your internal storage though. Before you get off Oxygen you can use Titanium Backup to backup your user apps and then you can restore that backup once you've flashed your new ROM. So essentially you keep all of your apps and their data. Just don't backup/restore any system apps or data/settings because that'll cause major problems. If you need detailed instructions on how to flash you can check out my guide.
