I'm getting conflicting answers.

I started using the cm7 nightly's today & i'm getting different answers on which to wipe between nightly's. Cache AND Dalvick or just one of them? Some ppl are saying u only have to wipe cache, i've seen just Dalvick & i've seen both. I'd asssume both but don't want to go thru an extra step if it's unnecessary. Thanks alot guys

It really depends on what changed in the nightly. It never hurts to wipe both, but it is usually the case that the system is smart enough to just rebuild odexes for the things that have changed therefore, I'd just go with the cache. I rarely wipe anything between CM7 flashes even many builds apart, but I live on the edge.

I've never used ROM manager so I can't say, but that sounds like the way to go.

I've had bad luck w/ Rom Mgr soft-bricking my phone. I prefer CWM.

Ok, thanks alot guys! I just wanted to make sure & yea, rom manager just doesn't feel as comfortable to me as doing it manually where can see what's going on & abort & restore if i can see something not going right. Mainly i just wanted to know if it was ok to download the rom from rom manager & then do it manually from there. Thanks again fellas :')

[Q] upgrading

ive been rooting my phones for the past couple of months now and recently been trying quite a bit of different roms and kernals, but i have a question if anyone does not mind answering for me. When doin a upgrade on on a certain rom would you recommend to always wipe: data, cache and dalvik cahce....thank you in advance for the help

It is recommended to do a full wipe, dalvik cache if you going from one type of Rom to another. Ex. from CM to Muiu, if you just trying to tests different version of same rom, full wipe is not necessary, but still recommended.

thanx for the help really appreciated....

It's for wiping /system, /data, and /cache. It also converts system back to ext3. It works on Gingerbread also. I don't recommend it. Just manually wipe through CWM Recovery.

Thanks for the info

Is that ALL it does?
Is that really required?
Have people become so lazy that they need this?
Or am I missing something here?
Before I flash a new ROM, I always (manually through clockworkmod recovery) wipe data, system, cache, dalvik.
Or does this do something else?

Good for you,would you like a cookie?
The app is meant for newcomers who might not know what all to wipe when flashing roms.

Yes please drunk bastard. I'd like a big glass of milk, and some cookies.
I just never knew an app like this existed.
I'm just shocked, that's all. I've not come across it before.

Thanks for this thread, very informative. I was under the impression it did more than that >_>.

Raises hand...
I "wrote" it. Yes, it is really that simple.
The truth is, of course, nothing is done in a vacuum. I was heavily inspired by BackToExt3 for the 2x by PaulOBrien. Of course, the g2x has some differences so it's not the same script, but basically does the same thing.
Yes there are other ways to do the same things, but once you have the script on your sdcard, it's the fastest way to wipe -- even for experienced users.
However, if your file systems were fully converted to ext4 (not just mounted as), and you want to flash to a bone stock rom without ext4 support, this script takes care of all the steps.

I added my thanks because it saves a lot of button pushing and possible errors when doing a lot of rom testing. It sounds like some others had bugs too which scares me. I'm also grateful for not having to do a lot of additional hunting for more info on proper cleaning for the "safest" flash.
So thanks again.

About Updating ROMs

So, I gotta ask, what's the deal with devs not posting explicit instructions on how to update their own ROMs? Usually if I ask in the thread, somebody just gets pissed and says "Search for it!" I do search for it, but I can never find it. Is it just an assumed task that every ROM upgrades the same way?

Yup. Most of them.

...Then what is it? I have yet to figure out... Do you have to always do a clean install?

Depends if it's a wipe or non wipe update. The op will say

Why would you think updating from say 4.1 to 4.2 would be different than 4.0 to 4.1?

You talking about sky ics? Totally different ball game there. Weird.
Sent from my SAMSUNG-SGH-I727 using Tapatalk 2

Most roms are pretty straight forward & stated clearly in the op...if its skyics thats a totally different .
If its a update:
1.Wipe cache & dalvic
2.flash
3.reboot
New base rom:
1. Factory reset
2. Format system
3. Wipe dalvic
4. reboot
Thats my method & I've never had a problem.

A clean install would always be ideal (even if its an update)

Mmkay. That sounds like a good guide to go by. Thanks for the replies everyone! Much appreciated!

Dirty vs Clean

I know this is simple stuff, and I probably already know the answer, but there's no specific thread on it that I could find by searching.
What's the difference between a clean flash and a dirty flash? Just wiping the data, dalvik and cache?
I'm new to flashing on the S3. Thanks
Sent from my SCH-I535 using xda app-developers app

Yeah a clean flash just means you wipe data in addition to wiping cache and dalvik. While you only wipe cache and dalvik in dirty flashes. You're usually guaranteed not to have issues with clean flashes but you lose your app data.

I always clean= wipe data

That's what I thought, but just wanted to make sure it wasn't some extra step I didn't know about. Many thanks

Format data and wipe system is what is needed for a clean wipe (plus caches)
