Some rom guides tell you to wipe data/factory reset after you have.flashed the rom but wouldn't this put your phone back to stock firmware?
What is non wipe and wipe because I have tried both and they wipe everything.

You can find Wipe- and Non-Wipe versions on some ROMs. So you can choose if everything should be wiped or not.
Factory reset = removing all user data

If you are updating same rom then generally you can use non wipe version, if you are coming from a different rom then use wipe to avoid data conflict

Wiping after flashing won't put your phone back to stock but may put it into a bootloop. Most instructions say wipe data before flashing, this will prevent any compatibility errors you may have with an old rom or version. Just remember to backup in case things go wrong.

Noob questions. Every time I flash a new rom I become narotic, and I first disable any lagfix, then go to cwm, and factory reset, cache, dalvik, and batt stats all wiped. I'm assuming I don't need to do this if it's a full wipe rom? Can I even skip the lagfix part or is that always necessary?
Also if I'm upgrading a version of a rom, ex, apex 6.4 to 6.5 or any other situation same as this, can I just flash it without doing any prep before hand?

if it's a full wipe ROM than yes, the ROM does all the wiping for you. And if the OP states for you to disable lagfix before flashing than i do so.. also if your just doing an update you can usually just flash over one another. But its always good to check with the ROM dev and see if he suggests any special wipes or whatnot.

You can still do whatever your used to and are comfortable with. BUT this is what I do before flashing any rom.
I go to market and make sure all apps are updated.
Next I go to titanium backup and backup all user apps and system apps with data (I NEVER RESTORE THE SYSTEM APPS OR DATA THOUGH)
Next I boot into recovery and perform a backup (which saves almost Evey aspect of my rom I am on before flashing
I boot back up and then reboot into recovery again.
Then I install whatever rom I am flashing at the time.
I DO NOT WIPE ANYTHING OTHER THAN CACHE WHILE IN RECOVERY AND BEFORE FLASHING THE ROM.
I have NOT had more than 1-2 issues flashing anything since I started using froyo, so that includes any froyo rom, the gingerbread rom that first was made, then Continuum and on my second cappy the same except I also have flashed CM7 on it.
The one or two times I had issues ALL I ever did was boot into recovery and run restore from the previous rom I was on. Then reflash the rom I was trying to get on to. I really have have had NO ISSUES NOT wiping anything other than cache.
I look at it this way, if it works the first time I flash a rom I am golden and do not need to reset up everything. If I have a issue then I CAN start from scratch with a factory reset and wipe cache and dalvich cache IF NEED BE. At least then I am ON the rom I was trying g to go on in the first place.
Then after all seems good I will restore my user apps and some user apps with data with Titanium Backup. So MOST of the time I have changed roms and all is working with no issues in 10 to 15 minutes.
Again this is HOW AND WHY I do it that way. A NANDROID BACKUP and TITANIUM BACKUP are your BEST FRIENDS in these cases.

6.5 is a wipe version which would take care of wiping caches. You dont need to disable lagfix. But as someone said always keep a nandroid backup
Also you may want to post these queries in ROM thread for quicker response
I always disable lagfixes just for good measure. Most roms do a full wipe so there's no need for any of the other stuff.
So every single rom for any phone I've seen says to clear the dalvik and the cache (or maybe its just the "dalvik cache") but when I went from stock to Thriller, I forgot to, and nothing went wrong. In fact, all my settings and apps were all intact from the previous stock rom.
I've considered that the only other phone I'd done any flashing on was a backflip, without Apps2SD and maybe that's why all my apps and settings were intact, so that still leaves me with the question: why clear it?
This may be a noob-ish question, and I apologize. Thanks for any help!

If there are any compatibility issues between the apk dalvik cache of your previous rom and the apks on the new rom wiping dalvik clears the previous apks stored dalvik cache. In most cases you can flash without a problem. But I recommend wiping between rom flashes just to eliminate any potential problems. Flashing something like Thriller over the stock rom you can probably get away with not wiping anything since all the apks are essentially the same. Flashing kernels you don't need to wipe anything. When flashing a rom with a completely different firmware I recommend a full data wipe. Restoring recovery backups such as nandroid require no wiping at all.
Also, wiping dalvik shouldn't affect any of your settings.

When switching ROM with different base apps, it is generally better to wipe caches than to get stuck in a boot loop, or having your apps and launcher FC on you. You never lose anything as the cache rebuilds itself on the next reboot, except maybe a few minutes

If you followed the instructions you did a full data wipe. When you do this the dalvik gets wiped as well. To just wipe dalvik look under the Advanced menu in cwm recovery.

clearing cache
i am using a nand rom in my HD2, and i also want to install another rom via SD in Magldr, but because of kernel issues i cannot load the Rom from SD unless i use the kernal i am advised to use. I am instructed to clear the dalvik and cache, but does this mean that i would lose anything from my current NAND rom? I still want to be able to use that of coarse so i just want to make sure there are no major risks when clearing cache.

Clearing dalvik and cache wont make you lose anything, used to do it with my shift because I'd flash about 10 zips a day sometimes...
Also when it comes to flashing any ROM I format system data cache wipe dalvik cache and do a factory reset just to be sure nothing from a previous ROM is left over also wipe my SD ext partition when running an a2sd ROM, my question is can I safely manually format the emmc partition of the thrill from the mounts and storage option of cwm

I am currently on stock+cfroot LA3. I have attempted to flash several custom ROM via CWM, however I always seem to get a bootloop. I follow directions first, then try the various other directions culled from other posts.
At there prerequisites to flashing a custom ROM such as being on the same base stock add the custom you are trying to flash?
what steps are you following? List them here please.

First is to follow the steps detailed in the ROM post exactly. Some recommend a full wipe, while others don't. Then I boot into CWM, select the zip file from sd card, wipe cache and dalvik, and reboot. Next is to try a full wipe regardless if I get into bootloop.
Looking about I realized that "full wipe" means different things to different people. I'm still curious if there are prerequisites such as the same base before flashing.
Curious about this cos i'm in your boat too. Follow everything but still get bootloops.

ive had the same issue too guys, for me, i started again with KKA, rooted it, and then flash my roms over that with the CF kernel, that works for me, but ive always found installing other roms over fm kernel or abyss will not work on my note, i get bootloops.
When flashing a stock, you should also do a full flash, use the pit file and bootloader if its avail and flash the lot, this way your getting a proper full flash, not just the 3 file method, but be careful and read up first, flashing bootloaders can be risky.

you should change the order you did, like this
if rom need fullwipe.
1. boot into recovery.
2. full wipe.
3. wipe cache and dalvik.
4. select the zip from sdcar.
if rom no need to wipe, ex rom of criskelo you only boot in recovery and select zip file, but you must flash over other custom rom.

In CWM, I don't have an option for "full wipe". I have:
* wipe data / factory reset
* wipe cache partition
and under the Advanced section:
* wipe Dalvik Cache
* wipe Battery Stats
I'm guessing you mean wipe data / factory reset? I HATE to guess!!
Another option that looks like it COULD mean "full wipe" is:
*#*#7780#*#* (on the phone keypad)
There's even:
*2767*3855#
I'll try with the wipe data and see what happens.
Yes, a full wipe or clean wipe is, factory data reset, wipe cache partition and dalvik wipe. So the 3 before flashing a rom and you shouldn't have any issues

Interesting that the first post AFTER the link is someone attempting to define "full wipe"!
I'll add the link to the Tips and Tricks post for future reference.
I have the following problem:
I have RocketROM v12 - ICS - 4.0.4 - XXLRT.
After I put my new simcard in the Galaxy Note, my Galaxy Note went in bootloop.
I can boot in CWM and download.
I have an older Nandroid backup and I did a new Nandroid backup without any problem.
On my internal SD-card I still have the above described ROM.
After re-installing the ROM I still have the problem with bootloop.
What is the best way to get out of the bootloop without losing my Nandroid Backup?
Have you done wipes of dalvik and cache? Do those first, see if it still remains.

may be do a wipe cache and dalvik.. and check.. if no go then do a factory reset from cwm

Thanks. I did wipe cache and dalvik, and the bootloop still remains.
If I do a factory reset, will I lose my Nandroid Backups?
no ur internal and external memory will be untouched
Thanks for all.
I am out of bootloop without lost of backup
Wow
hey guys,
which is the best method to clean your phone before flashing a new rom, or maybe bringing your phone to the state it was just after flashing a new rom. i tried data factory reset, wipe cache , wipe dalvik with kernels we have here and i found remainents of zip files i had flashed after setting up my rom and using newer mods. i dont want to format system, preload all the time.
which is your perfect, effective method ? speedmod kernel and its recovery or phillz , then which version ?
thanks

why you dont want format system and preload before flashing rom?
what I do before flashing any rom is:
flash philz kernel
wipe data / cache / dalvkk cache
format / cache / system / data / preload
and then flash new rom
and thats it, with this procedure I have never faced any issue with any rom I have flashed.
usualy I use this method even befoe restoring my nandroid backup.
above methods I using with philz and speedmod, but i prefer philz when wiping and flashing and making backup, because it has nice cwm for doing that. but after I flash new rom I immediatly flash speedmod because it is the better than philz if you drive your new rom, and you are not in cwm at the moment
hope this helped

completely agree with you djoni, but when you are flashing continuously, experimenting a lot ...you know ...this and that,
isnt a data factory reset , wipe cache, wipe dalvik supposed to bring you to that condition just after booting up after a new rom flash ? why were there remanents from a mod i had flashed after using the rom for some time ?
