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.
Sent from my ADR6300 using XDA App

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.

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!

[Q] updating a ROM - flash what? wipe what?

I want to update my Unofficial CM10 +3.x Kernel to the latest update from Hashcode.
UNOFFICIAL CM10 + 3.x Kernel for Kindle Fire [09/16 CHARGING+]
When you do an update like this, do you wipe everything like I did when I first flashed the ROM? I mean, when I installed, I wiped system, factory reset, cache and dalvik cache. Then I flashed the ROM and then I flashed gapps.
So now I just want to update the OS, what do I need to wipe? And will I need to flash gapps again?
CAn't ask this in the development thread 'cause my n00b hat it still too shiney.
Thanks!

A question like this doesn't belong in the development thread because it isn't development related.
If you're going from one ROM to a different one, you need to wipe System and Factory Reset (data and cache).
If the ROM is simply an update of an existing ROM, generally all you need to wipe is data and cache. There are always exceptions to this so it's always a good idea to make a backup in case things turn sour.
After installation of the ROM you have the option to wipe cache and dalvik. It isn't required but not wiping them has been known to cause some bugginess.

Thank you once again, soupmagnet. Yeah this is just an update to my current ROM. So .... I won't need to flash gapps again?
I'm slowly figuring this stuff out. hehehe... When I was 30 I picked this stuff up quick. Turning 60 on Thursday and stuff tends to need a little more pondering lately. hahaha
Anywho.... thanks

Oh, yeah. You need to flash Gapps if you wipe system.

OK, see, now you're messin' with the old man here... hehehe
On one hand I'm hearing if I am only updating my current ROM, I just wipe data and cache.
Then you tell me I have to flash gapps if I wipe System.
But prior you said I only need to wipe system if I'm going from one ROM to a different ROM.
So.... I'm just updating my current ROM. I wipe data and cache, flash the updated ROM, wipe dalvik.... done...
no flash gapps, right?
I need to look at TWRP again to see exactly how it presents the choices. Don't be hatin' on the old guy for bein' dumb now.
OK, booted to TWRP. When I select Wipe my choices are : Cache, Dalvik Cache, Factory Reset, System and then External Storage. So... in your first answer to me when you said to go to a different ROM I should wipe "System and Factory Reset (data and cache)" it appears you are telling me that "System and Factory Reset" is another way of referring to "data and cache". Is that correct?

Gapps go in the /system/app folder so if you wipe the system partition, Gapps will go along with it.

GAaaahhh..... I just wiped System and watched as it processed /system
and then I wiped Factory Reset and watched as it processed /data and /cache
So I guess that answers my confusion.

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

Should be an option in mount storage or advanced section of recovery to format .

STOP!!! TWRP is known for messing up your phone when you format internal memory. It will lead to bootloops and even the rom not booting at all. Switch recoveries to Clockwork or Philz and you will be fine. You may need to Odin back to stock to fix the issue first.

What to Wipe in TWRP
If you are switching ROMs (changing from one ROM to a completely different one) then you should perform a factory reset. A factory reset wipes data and cache (which includes dalvik cache). A factory reset will also wipe sd-ext and android_secure if your device has those items. 99% of the time, this is all that you need to wipe and you only need to do it once, not three times as some people would lead you to believe.
If you're installing a nightly update, then oftentimes you don't need to wipe anything at all. However, if you encounter strange behavior, then you may want to consider performing a factory reset. Of course, if the ROM maker recommends that you do a factory reset during an update, then it's a good idea to follow their recommendation.
The vast majority of ROMs wipe system as part of the zip install. This means that in most cases you do not need to wipe system... ever.
At this point, cache (not dalvik cache) is primarily used for recovery. It's used to store the recovery log and for storing OTA (Over The Air) updates. You probably don't need to wipe cache, and cache is already wiped as part of a factory reset.
In most ROMs, dalvik cache is stored in the data partition, so if you do a factory reset, you've also wiped dalvik cache. In a few custom ROMs, especially on older devices with small data partitions, the ROM maker may have moved dalvik to the cache partition to provide you with more room for apps. Since we wipe cache with a factory reset, again, you probably don't need to wipe dalvik. There are a few situations where you may need to wipe dalvik cache when installing updates, but you will know that it's needed when you are greeted with force closes when trying to open some apps.
Depending on your device and its configuration, you may have options for wiping internal storage, external storage, sd-ext, android_secure, and/or an option for formatting data. There's almost no reason that you would ever need to use these items. These options are there for convenience. For instance, if you're getting ready to sell your device, then it's a good idea to wipe everything on the device so that the new owner doesn't get your private data. Note that these wipe options may not be completely destructive. If you store especially sensitive information on your device or are really concerned about your private data, then you may need to look into other options to ensure that your data is fully destroyed.
