wipe data(factory reset). people will also tell you to wipe dalvik and cache, but thats pointless since wiping data(factory reset) also wipes the dalvik and cache. some ocd individuals will tell you to wipe even more, but thats not really necessary.
Im not sure if im OCD but I do factory reset 3 times.. haha probably not necessary... but it doesnt take long after the first time and since in twrp your still on the screen I hit hit the enter key 2 more times... lol

only 3 times? i know people that do it more, plus dalvik and cache 3 or 4 times. and i know people that will complete wipe the partitions of the phone, so the phone has no rom and is completely blank, before they flash a new rom, lol

The last few times that i have wiped dalvik cache i get this
Cache wipe complete.
E:unknown volume for path [/sd-ext]
anyone have any ideas what this is/means?
thanks!!
Pretty sure this happens to everyone. It happens to me at least - don't worry about it is the point. dalvik is still wiped.
ok thanks as long as its nothing to worry about.

Agreed, always get that error.

ditto happens to me as well
I have a quick question. When switching ROMs should I also in addition to factory reset, also perform a system/wipe to wipe the already installed custom ROM? Thanks.
It is generally unnecessary, but not a bad idea to do so. Most devs have their updater script format /system, but you'll find the occasional one that omits that one line.

Alright. So I shouldn't worry about performing system wipe?

I think it's better to wipe the system. As I've faced many kind of froblem because of a dirty flash. And I've seen many bug reports on several ROM thread and it just came out that it's not the ROM but the dirty flash is causing the problem. It will probably take 1-2hr to get back to the previous position so what's the big didfference??

OK. So when switching ROMs I should perform factory restore, wipe all caches, as well as system/wipe to erase the ROM currently installed. I have done it that way before but I always get nervous when I wipe system, cause now it has no ROM installed at all and I don't want anything to happen in that case. But thanks for the quick reply

What could happen?? Hardbrick?? A little chance..... Here's what I think when I do something risky. Just Think like I don't have any device if I can get this device back it's bonus for me.
You can always flash a rom whatever it has one or not untill your device can be booted into fastboot. So don't be afraid if something bad(!?) happens and you can boot into fastboot mode. Once I even had no boot just the fastboot it took less than 5 min to get a system on it.
And dirty flash is always an option. I myself had and seen many people having problems with it.

Don't just say thank, there is a button for thnking.
Clean is always the best! But always make a backup before the wipe process!
Wipe:
/system
/userdata
/.android-secure
/dalvik-cache
/cache
After flashing MIUI on my N4 and going back to a nandroid of a previous AOKP rom, I am getting a "Unfortunately, System UI has stopped" message over and over. Also, I noticed that after going to another rom (either nandroid or clean flash), there are some files left from the previous rom (e.g., flashed Carbon then went back to nandroid of AOKP and had a PIE remnant, which I know is not present on AOKP). I'm figuring this has something to do with things not getting completely wiped (all this is after complete wipe in TWRP between flashes).
Anyone have any advice on how to get a complete wipe between flashes?
Thanks in advance
Wipe cache, wipe system, wipe dalvik cache and factory reset. Do all those in recovery mode.

I did all those. Although, if I remember correctly, there's no option to wipe system in TWRP. Not sure. But I did wipe everything I could in TWRP recovery.
Thanks though.

This happens to me to for some reason even if I do wipe system. The wallpaper from my previous ROM almost always gets carried over for some reason

This happens if you have it set for your apps and settings to be restored by Google. I never advice this

After this flash ROM, then skip set up wizard and go to settings > backup and reset and do a factory reset from there. It will reboot. Then everything from the other ROM should be gone.
Hit thanks if I helped

But will I have a ROM to go back to? I mean if I do a factory reset after flashing the ROM that doesn't erase the ROM?
Oh, and what if you're trying to restore a nandroid?

Doing that after a rom flash can cause issues. That is why I always suggest to doing a full and proper wipe before flashing. Though it does seem that MIUI for some reason doesn't always properly remove files when this is done.

What? A factory reset clears out user data and restores the ROM back to the way it is after a fresh install. It doesn't touch the system partition.
You do know that titanium can restore app data from a nandroid, right?
The noobness is strong with this one.

I never thought about the rom being left intact after a factory reset because I only do a full wipe when flashing a whole new rom (I've never wiped after flashing a new rom, only before). And yeah, I use Titanium Backup.

Google's built in backup can do that. Many custom ROM's custom settings can be restored as well if there are provisions in the ROM that allow that data to be backed up to the Google servers. Many of the custom settings I use on CM are restored by this mechanism in the rare event of a wipe. With "App Data" being able to be synced with Google's servers we'll see much more of this as well; I think it's great.
These are "non-essential" settings that won't/shouldn't affect stability, etc...

I've just sold my Nexus 7. I sold it as is, rooted already. Now I just want to wipe my data and any apps or app data I've left on it. I've done this before but I always mix up the options and end up wiping everything off the tablet. I believe I've got TWRP on there. Which option is the best for me? Thanks for the help.

Take your battery out, then re-enter recovery, clear cache and reboot. If it doesn't work, simply reflash via Odin to correct it.

In future, read a lot more, or don't mess around with your device. The amount of people that go on about "puking, Sick etc" is unreal. If you don't know what you are doing. don't do it. It's that simple.
