Rom flashing question

So I have a quick question for everyone here.
Is there anything else I need to do to clear all remnants of an existing ROM from my phone other than factory reset/wipe data and wipe cache before installing another ROM?
I seem to have residual bugs from a previous ROM on my current ROM. Maybe it's kernel related? I don't know. Any advice?
Edit: Gah. Sorry wrong forum. Please move.

Try wiping dalvik cache from recovery. Its in the advanced tab i believe.

What i usually do is go into the partitions menu and format data / system / cache, and then i go into advanced and format dalvik cache, and then i go to the main screen and do format data factory reset and then format cache... i do all those twice so its 100% gone absolutely nothing lingering around

Awesome. Thanks guys. I'll give that a whirl.

I have been checking the box in ROM Manager to clean cache and wipe when flashing new Roms

and then ... ?
After all this is done, and the new ROM flashed, what can one restore from Titianium Backup without restoring incompatible/bad stuff? Thanks

Don't restore system data, especially if you're going from a 2.1 rom to a 2.2 rom.
I always just restore user apps and data.

Having a huge problem with my phone not wiping.

Okay, I was on AOKP M4 and I wanted to upgrade to M5.
So I backup everything and make a backup of my ROM. I wipe the phone and caches and flash M5 with the GAPPS, with the latest CWM touch recovery. When my phone reboots I notice I have the same wallpaper as before and when I unlock my phone my pin is still requested and all of my apps and settings stayed exactly the same. I was never asked to sign into my Google account and the start up/set up screen never came up. I checked to see if I even updated and yes I was on M5. Now the ROM isn't very fast or smooth and I get a lot of force closes and things not working properly.
I tried the whole process again with the CWM non-touch recovery, and again my phone did not fully wipe and all my apps and setting remained exactly the same.
I tried it again with the TWRP touch recovery, and again my phone did not fully wipe and everything was the same and my phone remains kind of slow and I'm getting a lot of force closes.
Why is my phone not fully wiping? What can I do to fix this?
I would really appreciate some help!

you need to wipe factory / data.
wiping cache and dalvik doesn't wipe "/system/etc etc etc"
1. Wipe Factory
2. Wipe Data
3. Wipe Dalvik
4. Flash ROM
5. Flash Gapps.
6. Flash Kernel
for full wipe.

Yes, that is what I'm doing. I'm wiping factory/data and I'm still having the same problem

Like with the TWRP recovery, I went to wipe, I hit factory reset, then cache, then dalvik cache and then flashed the ROM and GAPPS and all my apps and settings stayed the same. It was like if I had dirty flashed it. I don't understand what's going on.

***FORMAT /SYSTEM*** (under mount in CWM I believe)

What does that do exactly? Would I have to worry about my media and sd card being wiped?

Okay thank you, I guess this time in TWRP I'll do factory reset, cache, dalvik cache, and system and see if it works out

Okay, so I did factory reset, cache, dalvik cache, and format system.
I flashed M5 and GAPPS, rebooted and everything was still the same. My phone did not fully wipe.
I don't understand what's going. I'm so frustrated right now

I would do a factory reset, if that doesn`t help flash a stock rom and root your phone again. BTW don`t you have a nandroid backup to revert to

I have a nandroid backup, but that doesn't solve the problem of my phone not wiping.
I guess I'll unroot my phone and lock the bootloader and re-do everything to see. I don't understand why my phone isn't wiping correctly.

sometimes cwm just doesnt work with factory wipe. i've used it a few times now and sometimes it works and sometimes it doesnt. i have no idea why. you can try doing a factory wipe from the phone settings>backup and reset. ive only done that twice but it worked both times. if that still doesnt work just go with a fresh flash of google images using fastboot.

Init.d folders can only be wiped with a factory reset afaik, or manualy off course. By locking and unlocking the phone you perform a factory reset anyway, so i would flash a stock rom and start fresh. No chance on left files or scripts. You can do it with GNex Toolkit, option 8. Put the downloaded and not extracted .tgz file here C:\Galaxy Nexus ToolKit\put_google_factory_image_here and flash.

Thanks guys, I'll try that!

yes do all for the cleanest install, I only do this if switching ROMs, or a developer tells you too in his updated thread. Some do it after every update. Basically I just overwrite old ROM with new update, which doesn't erase your data(always wipe dalvik and cache prior to doing this). Wiping data erases everything you've done to the newly installed ROM. Sometimes not doing a clean install even from the same ROM update can cause issues with certain apps that are reading your data. I had this issue with one app last update to jellybomb jb ROM.

Assuming you mean factory reset when u say wipe data. If u actually choose the "wipe data" option it will wipe internal sd.
But yes all 3 should be wiped, however factory reset usually wipes cache and dalvik-cache too. So factory reset by itself should do just fine

Full wipe procedure

Hello,
It's been awhile since I installed a custom rom.
What is the proper procedure in doing a full wipe?
thanks,

I always do a factory reset first. Then wipe cache, dalvik cache, data, and system.

RE..Root?

Hey guys,When I rooted my GS3 I wasn't sure how but kinda stumbled on having it done. When I did it I'm sure I didn't do a factory reset, or wipe the dalvik cache either,is this called a dirty flash? My question is if I want to RE root my phone,can I just simply follow the same procedure even though it's rooted already, and then re flash the WS Rom?..Thanks and please understand this is all new to me so any and all help is greatly appreciated..Phil

There is no need to Reroot. Yea, you did a dirty flash. A clean flash involves wiping cache, dalvik, data, and system. Sometimes it's a good idea to wipe your internal storage as well, copy everything you want off of it and then wipe. I always wipe everything 3 times, just habit. Then flash away!

Thanks, so I can just do a factory reset, wipe cache, wipe dalvik, and then re flash my rom? Cool, could this have anything to do with my battery life being bad after this?.. thanks again.

Factory reset isn't enough, you need to wipe data and system as well. As for the battery, anything could be the issue. A clean flash would help.

Update
Update.. I wiped my cache, wiped my dalvik cache, done a factory reset and system wipe ( I guess that's what it's called), and then reflashed the Wicked Sensations Rom, and my phone is operating much smoother. I read that after a new rom flash your battery should be re calibrated so I installed a battery calibrator. I'll post back in a few days with a report on whether or not there is a difference.
