[Q] flashing zips: when to wipe data/cache/dalvik .. etc

flashed SRF 1.1.0 a couple days ago (first time rooting and all -- yeehaw!), so this is a n00b question
i know that for that, i had to data data, cache, and dalvik cache
i've also flashed the Vision kernel, which ... seemed like it didn't require wiping data or cache or dalvik cache
i've also flashed an impaled keyboard tweak and that one seemed to require wiping just cache and dalvik cache, but not data (as i recall)
so... i'm just confused, and wondering... when do i know if i need to wipe data, or just cache/dalvik, or none at all?
i just flashed the AOSP screen lock zip .. didn't see any instructions, so i figure wipe cache and dalvik, but not data (didn't want to lose my texts was my thinking)... and i just made that up. and that seemed to work. but i figure if i knew the rules of thumb, i'd feel better like i knew what i was doing
any clues / insights would be super appreciated!!

The only time u wipe:
1.
Data/Cache/Dalvik
For a rom flash that says on the rom thread wipe wipe wipe
2.
Cache/Dalvik
Is mainly when u flash themes its reccomended
3.
As for kernals and other mods unless it says to wipe then you dont need to...

Nice info so far.
After you have done this a while you can start drawing from your brain through osmosis and you will understand: if it doesn't work the way you want....EXPERIMENT.

the above post is correct, sorta.
anytime u flash something that mods /system its good practice to wipe cache and dalvik cache.
flashing a kernel, u will want to wipe cache/dalvik cache just to be safe. it prevents any sort of incompatibility between kernels.
my 2 cents

[Q] Flashing Supernova extreme

Hi
I am try to flash Supernova ROM but I can't seem to get past the HTC logo.
I have rooted my desire using unrevoked and I have partitioned my sd card using gparted. I have tried wipe cache's and the davilk cache but it just doesn't boot at all. I am using stock 2.2 and haven't changed any kernals or anything. Anybody got any ideas. I am new to flashing on the desire. I am able to get back to recovery and have restored my back up. I just cant get supernova to work.
Thanks

You tried wiping? Was it successful or not? Wipe all/wipe cache/ wipe dalvik cache (advanced...) should give you "dalvik cache wiped" e.g. if succesful....

Yes all the wipes were successful. I wiped them a couple of times

I had the same problem but just pulled out the battery, did a full wipe again, booted again and it worked. If that doesn't work post this question in the Supernova thread

Coming from HTC HD2

Hi there,
I'm coming from the HTC HD2 i used to wipe my device using Task29, just wondering if there's a Task29 for the Gnex, i always liked to have a clean device before flashing a ROM.
Thanks for your help in advance

CWM:
Mounts>Format System. (Rom.zip's do this themselves...)
Wipe data/cache.
Advanced>wipe dalvik (this is wiped with the data/cache option...but some users are OCD)
Wipe cache. (This too is wiped in data/cache wipe...)
That's as clean as it gets.

Oh... i remenber doing that when sometimes i used to update my HD2 at work and couldn't Task29, so i am familiar with that process, thought using a native Android device was different
Thanks for pointing me in the right direction

[Q] CWM Wipe Data \ Factory Reset wipes everything

So I use to install custom roms all the time with no issues, but on my last two android phones I have to Wipe Data / Factory Reset, Wipe Cache, Wipe Dalvik Cache and every time it wipes the OS, then I have to re-flash. I have done the following.
- Unlocked Phone
- Rooted Phone
- Flashed CWM Recovery
- Create Backup...Can only use this once I re-flash the phone,
Xperia Ion JB
I miss custom rom's lol, any idea`s...

Resolved!!!
This is how I have to do this and still not sure why, but I'm a rookie so...
- Root Device
- Install Rom Manager (Fix Permissions) - Reboot
- Install Busybox Application (Install with Smart Install)
- Install CWM Recovery
if I don't follow this exactly the wipe data deletes everything and I have to re flash.

Have u tried "format data, cache" in mounts and storage instead of wipe? i think u might hv messed with cwm.. or may be the cwm version isn't for ub? hv u checked that? tried other versions of cwm?

Wipe Dalvik cache without root on android 6?

Hi,
is there a way to wipe dalvik cache without root (maybe via adb) ? I always wiped cache+dalvik after flashing a rom or update on my Nexus 4. Is that still neccessary with android 6?
I am using the stock rom without any modifications. I usually install updates with fastboot+factory image.

You can wipe cache in stock recovery

Yeah but you can not wipe dalvik cache in stock recovery. I tried to wipe Dalvik cache with TWRP (via fastboot boot TRWP. img) but I only get the response that wiping failed.
