A dirty flash is only wiping cache and davlik then flashing your ROM....
a Clean flash is at LEAST factory reset/data wipe + wiping davlik(factory wipe takes care of /cache also)... Maybe doing a format /system also.
SO let the games begin! Which is better?! FIGHT!!

If I switch ROM's I factory reset then wipe cache and dalvik cache. If it's a theme for example I only wipe cache and dalvik cache since the theme is suppose to be made for your ROM right?....don't see the reason to reflash the ROM as well.
Wipe data? What's that for? Is THAT why my phone won't turn on..........
Nightlies: No data wipe (yes to cache/dakvik)
New rom, even if it's the same android build: always, full wipe
Themes: No wipe at all, flash right on, right after flashing rom's. Don't like to wait for two bootups!

Il throw a vote to whichever works.. I usually dirty wipe.. If I have issues then clean it and try again.. With nightlies I tend to be fine dirty a lot, but even still I will do a clean every couple weeks just because..
why do so many folks wipe cache and dalvik after they wipe data? A data wipe/factory reset wipes all three, there is no need to do anything else.
I always wipe data, flash rom, then advance restore data only from a nandroid...dirty flashing in its most elegant form
So we all agree that a dirty flash is just wipe cache/dalvik cache.
Do you wipe prior to re-flashing, or afterwards? Does it matter?

What about flashing a new, updated kernel for a rom you're currently using? What steps should be taken for that? For example, cleanrom 2.1 comes with cleankernel 1.1, but the kernel has been updated to 1.2 and is out as a seperate download. How would you update just the kernel that's made specifically for the rom you use?

I disagree. I believe a dirty flash also wipes system. If you are 100% certain that your ROM build effectively wipes system as part of it's install routine, then you could skip this step, however I always wipe system to be safe. This works for me and I rarely need to wipe data or sd card(s).

When changing Kernels but not the ROM in a separate recovery session than a ROM flash, you don't need to "dirty wipe." Just wipe cache and dalvik. Dalvik wipe is key so that the dalvik virtual machine can be rebuilt by the new kernel.
Thanks for the info guys.
I usually dirty on nightlies until I have issues. Always clean when switching roms.

I find that this method works better than just wiping cache and dalvik, since im advance restoring data over a clean flash. both ways are considered dirty flashing tho.
I wipe dalvik, cache and battery stats. Works like a charm thus far. Wiping data is what blows out the IMEI correct?

Incorrect, flashing anything is what may lead to losing your IMEI. Backup using the appropriate tools in the development section. Btw stop wiping battery stats, it's not necessary.

Factory reset doesn't touch the davlik(Which I speculate(Guess) has to do more with the kernel than anything)

Usually when I flash a new kernel, or a different kernel, I just wipe the davlik cache and I am fine. There was some reboots after the first boot on the AOSP ROMs but afterwards it ran fine.

SlimSnoop is correct. According to one of the developers of a very prominent ROM the IMEI issue was because our phones got confused sometimes(Randomly phone to phone) and tried to reset during a flash. The data it tried to reset was bogus, therefor losing IMEI. He is also correct far as the wiping battery stats. It's only usefull when you have really strange results with battery. Google for the real reason to use them.
Far as backing up your IMEI so you will never run into the problem of losing it.... go into your terminal (almost every ROM has a Terminal emulator)
Type this:
su
then hit enter. Grant permissions
then type:
reboot nvbackup
then hit enter. This will make your phone do some shyt and reboot, but you really shouldn't need to worry about your IMEI after this. Regardless of how many ROMs you flash or what you do or who you date or who you kiss, etc... blah blah....
This really should be the end all for the IMEI...

New rom only when their bases are different , like going from ics to jb, or the dev says to do it (Even then Ill try it without a wipe because im lazy).
Themes I never wipe anything
Nightlies never wipe anything.
Edit: If I do have issues I then go back and wipe delvik and cache . That usually straightens out any issues and allows me to keep my setup.

Hi all,
on my very first flash of CM7, I had to install gapps. All worked well and I was happy.
Since then, every time I flash CM7, I get gapps already installed (yes I wiped all, yes I cleared dalvik cache, I even did the lock/unlock thing in order to clear all data).
I somehow get the feeling that my flashes are not a "clean" install.
did anyone else experience this as well?
thanks...
On your first time on CM7, wipe everything, flash cm7, flash gapps. When you want to update cm7, jus wipe cache and dalvik, then flash the updated cm7. No need to reflash gapps, no need to do a full wipe either.... unless you want to.
-Nexus S
So you mean that from now on. Gapps will always be installed? Even after full wipe/ factory settings?

That's not what he meant. He meant that if you are upgrading CM7, you do not need a full wipe at all.
But after a full wipe your Gapsps should be gone. It's weird that it is still there after a wipe. :S
It's still there after a wipe... is there a way to make sure I full wipe correctly?

Wipe Factory/Dalvik/Cache: Full Wipe
Wipe Factory: Removes Apps + Settings
Wipe Dalvik/Cache: Wipes the cache but your apps + settings remain.
Wiping factory will delete your Gapps.
Proper way to flash CM7:
1. Wipe Factory/Dalvik/Cache
2. Flash CM7
3. Flash Gapps
4. Flash Kernel (Optional)
5. Reboot

Upgrading to newer versions will now keep all your data in tact, so gapps will be there etc.
great, I think it's all sorted out now.
just one question though, I've read that CWM dalvic cache wipe doesn't work. Is that true?
If so, what is the best way to wipe dalvic cache and do factory reset (fastboot/adb commands are also welcome..)

It works. Somebody confirmed this, the error that pops up during CWR is SD EXT.
You can check for yourself, run a logcat (search the forum) while the phones booting.
Just want to make sure what it means of a full wipe. Does it mean wiping data,cache and dalvik ? And does this erase the applications ? Specially if your updating from a older rom ver. To a new one. Sorry for my noobness and thanks for the info in advance.

Full mean everything cache, dalvik cache, data, and even system this will delete all your personal apps. Do this when going to different roms (cm7 to miui, or froyo to gb) when updating the same rom its not really necessary, but you can wipe cache and dalvik cache (wipe these two when flashing kernels) just to be safe, dalvik and cache wiping will not delete your personal apps.

Follow fcisco13's advice. If you wipe data/factory reset from clockworkmod it will wipe data, cache, and dalvik cache all at the same time. So just do that and then format /system and you'll minimize issues.
As said above, if you're only updating to a newer version of the same rom, or to a new kernel, then just wipe cache and dalvik cache.

Hmmm ... during the initial setup of Android are you selecting to let Google backup/restore your apps and settings? If so then your phone will automatically download and restore apps and setting that were backed up to Google's servers from your previous installation.

First I would reboot to recovery, then wipe cache, in advanced wipe dalvik cache, then fix permissions. If the problem comes back , I would back up your apps, msgs, that you want, then, wipe system,cache, wipe data/factory reset, and reflash. Maybe a newer rom.

I did the first thing you reommended, it didn't work and to make matters worse, ma phone doesn't pass the boot screen....
I quickly rebooted in recovery and made a nandroid backup - followed your second suggestion but i never made a backup of ma msgs because you didn't say so in the 1st suggestion... i can load new roms but can restore from ma nandroid backup
When you wipe dalvik cache, your phone can and will take several minutes to reboot, because it's rebuilding the dalvik cache. Secondly, wiping dalvik cache and fixing permissions wouldn't cause your phone to not boot. Between my wife's and my phone, I've flashed Roms, updated, experimented, fixed, stuff, etc... hundreds of times, and never has a dalvik cache wipe / fix permissions caused the phone to not boot. Hesitant to try to help, because you seem to be blaming me..... But if you can't restore a nandroid, it could be you're on a kernel in which the nandroid backup/restore feature doesn't work, you are running an earlier ICS build.

ALSO.... it's the second time i am seeing where reboot take way longer than usual after restoring from a nandroid backup. I av done quite a few and reboot takes less than 10mins. I attempted one the other day and 2hrs 30mins later all i saw was the splash screen and boot animation, phone HOTT!!
This evening again, it looked as if it was going to do the same thing thing... it passed 20mins, i can't sit around waiting for that again
It sounds like a flash to stock KK4 (Full Reparation) would be your best bet. If you're already on G. B. bootloaders, I would recommend the NO BOOTLOADER version, no use flashing bootloader unnecessarily. After that, I would flash the rom of your choice, following the instructions in the O. P. line by line.
Maybe a lot more current rom.

I've been tinkering with androids for well over a year now and have rooted unlocked and s-off'ed amongst other things many different devices. For some reason I'm having trouble flashing kernels to my s3. Yes I'm unlocked and yes I'm flashing aosp kernels to aosp roms and touchwiz kernels to touchwiz roms. The problem seems most persistent on aosp roms and yes I've also checked that they both had the same cm10 commits. The only kernel I could get to boot was clean kernel on beans custom. Other than that no other kernels will work. The device will boot then the screen will start glitching up and then eventually bootloop. I've also made sure to wipe dalvik and cache plus fix permissions. I've also tried just flashing the kernel after doing a full wipe and starting with a new rom and have root 66ed back to stock and re unlocked. Is there something I'm missing here? I'm getting frustrated as I love custom kernels. Oh and the latest combo I tried was liquid smooth rc3 and lean kernel 1.0. Thanks guys.

Ofc wipe cach and dalvik cache before also.

*Wipe Dalvik
*Flash Kernel
*Wipe Cache & Dalvik again
*Fix Permissions
Works like a charm every time.

now when you odin back to stock, your booting into stock recovery after flashing the rom(root66) and doing a data wipe/factory reset correct? you said full wipe, but just want to be clear. it may be corrupted internal memory and might need to be reformatted.
I actually don't think I was wiping after I used Odin. I'll try that as soon as I get home. Though I have done plenty of factory data resets and system wipes, just not right after I odined. And you mentioned formatting how would I go about doing that?

Always perform a full/mega wipe as:
1) Wipe data/factory reset
2) Wipe cache partition
3) Wipe dalvik cache
4) In mounts/storage section wipe /system
5) wipe /data
6) wipe /cache
7) wipe /preload
Then flash new ROM.
For flashing a kernel, please perform steps 2 and 3.

If you want the new rom to run without any issue wipe everything. I always do wipe cache, dalvik, data, system. Do it a few times, even reboot recovery between. I always do and never have any issue.

I do factory reset then wipe system then flash rom and has work every time.
When changing type roms, Like sense to aosp . wipe evrything.
When flashing update or newer version of same ROM , you can dirty flash. Saves you setting up the whole device over again. Just wipe cache and dalvik.
Always check advice if wipe is needed.
Wiping the same things multiple times over is just for your own mindset. Once is normaly enough.

Thank you for this!
I only wipe system and both cache partitions when flashing an updated version of a ROM. If I am flashing a completely different ROM, I wipe data as well. There is no point is wiping anything multiple times.
So just to make things clear here. It is safe to wipe everythinggggg? Also when backing up before rooting or flashing a new ROM where exactly does the back stores? I tried restoring it and i couldn't find its location :fingers-crossed:
