Stuck in boot loop every time I flash a rom

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.

[Q] Restoring user settings after installing a new ROM

Hey guys,
I just installed CM7, which is awesome, but I'm wondering how everyone keeps up with the new nightly builds without spending an hour restoring their phone every day. Is there a way to backup everything about your phone - even your settings, shortcuts, widgets, etc. - and then restore those settings after you install a new ROM?
Any help would be very much appreciated. Thanks!

U don't need to wipe data between every nightlie, I only do that when going from cm7 to faux Rom or vice versa. Just wipe cache, dalvik cache, install zip, fix permissions , reboot.

You probably wanna flash gapps after the nightly, as well...or you won't have much fun.

+1 to this. You wont lose any of your installed apps or settings this way. If you've edited your build.prop file for Netflix then you'll have to do that after flashing a new nightly. And if you are using a custom kernel then you'll have to re-flash that after each new nightly.

between google backup and titanium i have pretty much everything restored in 10 minutes

what about using ROM manager?

All good ways, but I agree with the not doing a full wipe. But if you want to full wipe before each nightly another quick way to restore your apps is Android Commander, a pc program. Also, you do not have to do this:

Nice
Worked perfectly! Thanks to all of you for the tips.

How?
I have to wait for market to download every app (including titanium). I can't figure out how to get titanium running without waiting for it to get downloaded from market in some random order.
Thanks.

[Q] Need some help installing revolver please

Ok so I have mt TF rooted, CWM with backup done, I have the revolver rom on sd so do I need to do anything special like clear caches or anything and will I lose any of my installed games or apps ? I read that on Android rev hd you have to use super wipe lite and was wondering if you have to do that with revolver.
My tablet is brand new 3.2 HC but I do have some games and stuff I dont want to lose.
Thanks for your help.

I did not clear stuff for the first time, but it is recommended - and yes, if you wipe the system you'll lose your apps, but not what's on the internal memory (/mnt/sdcard)

As davebugyi said, it is not 100% required, but strongly recommended (you could run into issues if you don't do it) if you change roms. By that I mean switch between different roms, not just update your current one. I always do it when changing roms, using the CWM clear/wipe feature is usually sufficient (unless the ROM developer says otherwise in the intall instructions).
If you want to persist apps and app data, you can try one of the backup tools such as Titanium backup. I havent tried it yet with this device though..

Titanium backup
I use titanium backup to backup apps+data then do a complete wipe. Install revelover then restore titanium backup and all your files/games etc are restored.

Thanks Guys
I will do a backup with what you recommended and wipe then install. I just hope this revolver rom is worth it. Seems like everytime you look on the forum someone post a new rom.

best rom
The revolver rom is the best. One of it's features is when you click on the history icon it gives a list of history but they have a little red x in the top corner of each. Clicking the x closes the history for that screen. Keeps yout TF clean and fast. Other roms do not have that facility.
Enjoy

[Q] Eagles Blood CM9 to AOSP question

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,
-John

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.

Backups before Flashing

Hello fellow ROM-flashers!
What do you do too keep your setup when flashing, what do you backup? settings, data, accounts and so on.
Is there any good way to backup and keep your settings, and so on... or do you have to redo all that after you flashed a new ROM?
Perhaps its recommended to do it all over again and again? ... I use Pandoriam 5.7 and are happy with it :good:
But then again 6.0 around the corner I sure I want to have the latest update. Dont we all?
I find myself redo my phone settings more then I actual use my phone

Wouldn't it be awesome if there was a way to update it as you do with a stock ROM.. so you didnt had to wipe all when you go from 5.7 to 6.0 for example.
I guessing there are a lot of reasons why this isn't really a valid option... but would be great

..TitaniumBackup....
https://play.google.com/store/search?q=titanium+backup
in free version no batch backup / restore...
backup system+app data
wipe system / data / cache / davlik cache in cwm - flash new rom... installl TB ... restore all.... finish

This should be in the Q and A forum
But yeah, buying titanium backup is the best purchase you'll ever make if you often flash ROMs with full wipes. The batch backup/restore process is brilliant, I have it also saving my backups to dropbox so if anything happens to my phone, I have a copy there too (4G is awesome for this).
I've also found the best launcher is Nova, using Titanium Backup to backup and restore Nova, I don't even have to setup my homescreen again (4 sized widgets, 4 folders, completely customised - you can see it in the homescreen thread in the Q and A forum), even the widgets are there after a full wipe which wasn't possible with other homescreen launchers. The only thing I setup fresh each time is my work exchange account.
By the way, you mostly DON'T have to wipe between ROM versions. I always do because that's how I like to do things (and due to the above I have the process sorted), but most poeple don't..

When updating ROM's - I do a Nandroid + SMS/Call log backup + Titanium backup of all user apps +data.
I the upgrade the ROM over exissting without any data/cache wipe. If I run into FC's after updating the ROM, I either restore my Nandroid or do a clean install of the new ROM and restore apps + settings from my Titanium backup.

I use online nandroid to backup full data. Works a treat and you can use your phone while backing up!
