[Q] Dalvik cache to be wiped..??

When flashing new custom roms..
We wipe...via recovery select factory reset & wipe cache partition..!!
But do we also wipe dalvik cache before flashing together with the above step..??
What about after flash (i always factory reset/wipe cache partition) avoid force close error issues..
Can we select wipe dalvik cache after flash too (never tried just want to know if any harm will come.. will anything go wrong)
* if i did select all three reset/cache partition/dalvik > will it erase/wipe nandroid backup..??? *

For a wipe rom, I always backup, do a factory reset, flash rom, do another factory reset, boot, then wipe cache and dalvik cache. The dakvik cache is a temporary working area and can be wiped anytime, I clear both caches weekly or if I get any hiccups. Nandroid backups are stored on your sd card so dont get touched, but best to copy them to PC, just in case, keep the last 2 or 3

nandroid backup
So dalvik cache can be wiped any time...many thanks..
When i make nandroid backup via recovery mode, will android system only restore "last backup" or does it allow to choose "other backups"..???
(does it store multiple backups ? OR just one backup very last...
Thanks

You can choose which backup to restore. Standard practice is to wipe dalvik and cache BEFORE flashing.

Couple things on which way to do this when loading custom ROMS. What is the proper order of wiping, restoring and dalving cache?

[Q] Wipes and formats

One question, maybe noob ...
When we made flash a new rom from recovery, we made the wipes;
- Wipe cache
- Wipe Dalvik
- Wipe data / factory reset
But
I notice that when you make the wipe all data / factory reset, the system partition is not formatted, it influences the functioning of the new rom?
For sure, I always do the formats in "mount and storage".
- Format cache
- Format data
- Format system
Thank you! Hugs! :silly:

I only
- Wipe Dalvik
- Wipe data / factory reset
I thought when I do wipe data, then I delete the cache.
Sometimes I wipe SD for delete cache & thash of deleted apps.

Ok.
And the system partition?
When you wipe data / factory reset, the system partition is not formatted.
As I know the main files are in the system partition.

[Q] wipe cache and data?

hello there!
i'm a new little fellah in the rom flashing world, so i'm a little afraid before doing anything, so here's the situation :
i have a galaxy mini, rooted, and cwm is perfectly installed.
i want to install this rom : http://forum.xda-developers.com/showthread.php?t=2085347
In the description it's written to wipe data AND cache after every action.
I just have personally 2 thing to install : the rom and the gapps, that's all (no patch).
So i have to wipe cache and data before flashing the rom of course, and so my question is : do i have to wipe data AND cache after installing the rom? and then install the gapps, and then wipe again?
So should i do :
1) wipe data and cache
2) install from zip the rom
3) wipe data and cache
4) install from zip the gapps
5) wipe data and cache
6) reboot
Is that good? or am i doing a mistake anywhere?
thank you for your help !

normally this works
wipe data ,cache and dalvik cache
format system ( if going from stock to cm7 or vice versa)
install rom
install gapps
wipe data , cache
reboot

you can also wipe battery states but it's only optional, you dont have to but no harm in doing so.

[Q] What is needed to do when installing new rom?

I have found this from here:
FIRST OF ALL DOWNLOAD THE ROM AND THE ADD-ONS PACKAGE.
1. Back Up all Your Important Files as the Rom is wipe-only.
2. Copy the rom to SD CARD and Boot to CWM revovery.
3. Click WIPE CACHE PARTITION -> wipe
4. Click Advanced -> Wipe Dalvik - Cache -> wipe
5. Click Mount Partition ->
a. Format /System -> yes
b. Format /Data -> yes
c. Format /Cache -> yes
6. Click Wipe Data/Factory Reset -> yes
7. Install the rom
Some ROMs need just wipe data/reset factory and wipe dalvik cache.
SO could someone tell what is needed to do and what those 5abc means and are they really "must to do"- things?

All to be sure, to not have any conflicts...
With TWRP Recovery, go to "WIPE" section and check "Dalvik", "System", "Data", "Cache" swipe OK button and all it's done in one step
You just have to Install your new Custom ROM !!!

To be sure of the answer you can ask pulak861 as I see these are the instructions of his rom installation xD don't worry I think they're all ok just to make sure you don't have any issues while flashing your new rom and testing it then, I followed all these steps yesterday to flash the velocity rom and nothing unusual happened, before that the only thing I used to do was a wipe data factory reset, and wipe cache partition too.

When installing an update (not a new version) of the custom rom you already have it's not completely necessary to do a full wipe/data cache, but if you have fully working back up, do it just to be sure everything works fine

Extremely noob TWRP question

So I just started using TWRP and its awesome and I wanted to a simple cache partition wipe like you know the wipe cache partition on a stock recovery, so I was wondering if I should just select the Cache option in the Wipe menu or both the Cache and the Dalvik Cache?

i always wipe both, cache and dalvik - never hurts.

Thanks.
