Yes, if coming from a GB based rom you should wipe date/factory reset.
Is there any reason why you cant? All you need to do is backup apps/app data with Titanium Backup and then restore once you have fresh rom.

1. Yeah full wipe is recommended if you are downgrading or upgrading to another Android version.
2. If you don't do full wipe there are chances that your CM9 will not bee stable, freezes and lockups here and there

What about an ICS stock rom? that's the one I'm using right now . If I install the CM rom, and if I want to downgrade to the stock rom again, could I do that? Thank you for answering.

If you are moving from stock to Aosp Roms and vice versa, you have to do full wipe

Yes, you would just flash the stock ROM using Odin, and that would "unroot" your handset in the process.
If you try to switch from stock to a custom ROM, or between different custom ROMs without wiping your data, you can soft or hard-brick your handset. It's not worth the risk.

Hi. I've been wanting to root my phone. Is there a way to back up my apps before I wipe it and install the rooted rom so that I can restore them once I've rooted my phone? If not. What other options might I have? Thanks. Adam

You don't need to restore your apps after rooting your phone because rooting doesn't wipe anything.
You need a rooted phone and a clockworkmod or cfroot recovery to install any custom ROMs. For restoring apps, you can use Titanium backup. It's free and the paid version is even better.
Also, dont forget to take a nandroid backup before flashing a new ROM!
Okay thanks. But if I flash a rom does that not wipe the phone?

Yes flashing a new ROM needs wipe. It wipes your user apps/contacts/settings/messages, etc etc.
There are easy ways to get all of them back after rom installation.
A simple export,import could be used to restore ur contacts/messages, etc.
Titanium can restore your apps (with app data)
Your pics, videos, and other files will not be deletd on a ROM flashing !!

Yes if its a wipe rom no if its non wipe .Depends upon what sort of rom stock rom custom rom root kernel is not a rom /full firmware .
A Yes always backup you can not recover non backed up items .
Apps backup is Titanium Pro .
.and should not wipe anything .
CF Root and CWM should not wipe anything .

List is incomplete. Read ROM threads, and from user comments, you will know which ROM is best for you.

Whenever I install and ICS ROM it seems like it installs fine but then it just its at a black screen whenever I try to boot up. I'm pretty sure I'm following instructions right but I have no idea what's causing thus problem. Just ask if you need additional information.

do not use safestrap, this gains you lots of bugs and flash failures... it's quite not very 'safe' i think... use RAZRbootstrap instead...

Make sure you are on stock 2.3.6
If you are not on 2.3.6 then you will have to upgrade first and reroot before you can install any ICS ROM.
By the way, which ROM are you trying to install?

I am familiar with flashing. I had the LG Optimus LTE before this and flashed quite a few roms, This phone however has me awfully confused. I have been researching all day. And so far i am under the understanding that the touch cwm are not good and the use the 4.0.1.5 recovery. But what i don't understand is how do you install roms without wiping data/factory reset through cwm? don't most roms require this? and isn't that what causes the superbrick? Sorry for sounding like a noob. but can you tell me how you do your flashing?

Just use a different kernel, like siyah (www.gokhanmoral.com and make it's for the s2 not s3). Then you can wipe data. Just didn't not be on 4.0.4, and have a samsung based kernel (the kernel dev should have info in the op). Once you're on a safe kernel you can flash whatever you want and wipe data.

Yeah, you should be able to flash through Odin. And you can flash back to stock by getting a stock firmware from www.sammobile.com and flash through Odin

Yes I wiped data, cache and dalvik cache. Couldn't get into recovery so i just re-flashed my firmware via odin. All is good now and successfully flashed cm9 with no issues. Must have been a bug in the rom.

Just go to sammobile.com, download any stock ROM, and flash it with Odin. That will make your tab good as new.
Which one to flash? I remember some problems with WiFi and battery in some versions of 4.0

All of them are the same. I don't remember any problems with WiFi tho. There is a deep sleep issue but that is only fixable by installing a custom kernel.
