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.

[Q] N00b updating Custom ROM

I have installed MildWild CM-2.7 on my Desire but there is now MildWild CM-2.8 and I can't find a guide how to install/update my Desire.
I have got S-OFF and recovery by Revolutionary The guide I followed to S-OFF and ROOT
This is the ROM I using. MildWild CM ROM

Just flash it via recovery like you did with the previous version

Will flashing the new version cause me to loose everything on my current version I.e apps and data etc??
Thanks for the reply though

do back up first, wipe davik+cache and flash it... it should work if not do full wipe and restore back up
just post any result we will move from there

What should I use to hackup TIbackup? Or is there a better one that you reccomend?

Do I only restore the Titanium I am guessing, as restoring recovery would revert back to my current ROM? and I have thanks

Yes indeed. With titanium, only restore "missing apps with data".

ROM Manager can make updating so much easier - well worth the investment.

I can't speak for other devices but for Desire, nope it's not worth the time and money.

Things I've learned with all this flashing that may be helpful for you.
1. Before flashing, always backup your current system up. nandbackup via recovery, titanium for your apps, sd card if really needed for that you need to do.
2. If flashing an updated version of same rom, wipe cache and dalvik only on your recovery (unless explicitly specified by dev to make a full wipe.)
3. If you are having weird issues after upgrading the same rom, do a full wipe and start fresh. If issue is not resolved, report the issue to the Dev's thread.
4. Do a Full Wipe on recovery (System/factory, cache, dalvik if coming from a different rom).

Thanks for the reply.
In response to 2. I am using ClockworkMod as my Recovery and I am guessing you mean I have to wipe 'cache partition' and 'wike dalvik cache' under advanced?
I am creating a guide to help fellow N00bs how to update a rom and change between ROM's

Yes if I remember correctly there are the first three lines on that recovery is wipe system, cache partition (like you stated), and wipe dalvik. So if upgrading just wipe cache partition and dalvik cache.
System partition is where the "Android OS" resides. Wiping it is like formatting your computer. Most of the time, incremental updates of the same rom requires you to wipe just the cache partition and dalvik, otherwise if the rom update has a lot of changes, the dev might require you to wipe all three options on the recovery.

Having wiped my cache and dalvik cache. I am now wanting to install the new version. On the main screen I have 2 options which are tempting to click.
One is 'Apply update from SD card' and the other is 'Install zip from SD card'
I am unsure of which to choose but my gut instinct is to go with 'Install zip from SD card', is this correct or am i going to make a terrible mistake?

Install zip from SD

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)

5. Flash Gapps.

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] When to reformat and/or wipe data and/or cache and/or dalvik cache

Guys I tried searching and only found this thread http://forum.xda-developers.com/showthread.php?t=1147152&highlight=cache+dalvic+wipe
which didn't help me at all
Can someone please explain when to do each of the following?
Reformat
Wipe Data
Wipe Cache
Wipe Dalvik
I want to have the cleanest install, so do I do all?
Thanks
I will give thanks to all that help me clarify when to use what in what combination

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

[Q] Remnants

Hi there, apologies if this is a silly question. I'm not an expert by any means, just a guy who follows the directions given on helpful sites like this.
I recently flashed the Slimkat ROM onto my n7100 for various reasons. But when I did, I obviously didn't completely wipe everything (which is what I intended).
Because for example, I installed a couple games on there and found that my game-saves were still there, also there were some bits on the obb folder from apps that I had on my phone previously but haven't installed since flashing the new ROM.
Why is this? Did I maybe miss a step when flashing the ROM? I know I did the 'wipe and restore factory settings' part in CWM, but I'm not 100% if I did the part with wiping the dalvik and cache etc.
Would that be the reason?
And If I want to give my phone a completely clean wipe what's the best way to do that now? Would I have to go through the steps as if I were flashing the ROM all over again? Or could I just go into recovery mode and wipe the dalvik, cache, system, data etc and reboot?
P.S. Yes, I know that no one who gives advice is responsible if I brick my phone.

Just a follow up - I did a wipe + factory reset, wiped cache partition, wiped davlik cache, and was surprised to find I still had leftovers on my phone. For example I had some episodes of a tv show in my downloads folder and also there was still app leftovers in the obb folder. Meh... I'll just delete stuff manually.

Well, you will have to flash stock recovery then. after that, wipe data/factory reset and wipe cache. This will erase everything on internal SD card. I assume u have backed up EFS and other important stuff.
press thumbs up if u find this suggestion helpful.

By the way, I sort of overlooked the obvious - in the end I just did a factory wipe and reset from inside Slimkat i.e. not via recovery mode.
And that did the job fine. Cleaned up several gigs worth of clutter which apps like SD Maid seemed to have skipped over as well.
