If you're installing a new rom, ALWAYS do da factory reset, wipe dalvik cache and cache partition!
On the other hand, if you only want to install an "update" (new version) of the SAME ROM you already installed (MIUI for example), you don't need to do factory reset, wipe cache and dalvik cache is enough, copy and flash the updated rom and enjoy in the new version with all your data/apps/messages etc. there!

can u tell me what is stored in Dalvik cache?

if you're on stock roms, then going to cm/miui, do this:
go Recovery
-wipe dalvik cache
-wipe cache
-wipe data
-install the rom
-then it will reboot automatically(or after installation, reboot) then it will bootloop
-remove battery and put it back in, then do 3 button combo (recovery mode)
then install the rom again,
-optionally install kernels, etc
-reboot.
or if you're coming from a same rom, but new version, you don't have to wipe, just install the new version of rom.

I would recommend to never format boot, if not done correctly it may brick your phone.

Hi, I'm using nitrogen OS on my Redmi note 3. It got updated to 8.1.0(Oreo) through flashing from 8.0.0(Oreo). While doing so I didn't clear the necessary cache like dalvik, system in TWRP. Is it necessary to clear the cache in TWRP while upgrading in the android version?(Though I'm using same AOSP based nitrogen os for 8.0.0 & 8.1.0)

[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] How to install correctly?

Hi there!
How is the correctly way to reinstall "CM10.1 native emmc" on my nook? I have have installed 10.2 and want to delete all user data. I´ve tried, but real racing 3 has the right version, after installing.
I have tried following methode:
wipe data/factory reset
wipe cache
wipe dalvik
--unter mount & storage (auch Recovery):
wipe/format cache
wipe/format data
wipe/format system (am wichtigsten!)
wipe/format preload
Preload was not to find in my cwm.
Then I flashed the new file an d wipe cache wipe dalvik cache.
My personal game data was still on the nook.
Can anybody tell me, how to install any version of cm by deleting all data?
Greetings from germany (please forgive me my bad english)

Yes go to mounts and storage and format 'data and datamedia'. That gets rid of your media files too (where that game data is stored).

When you flash another rom I recommend wiping: Data, Cache, Dalvik Cache and System.
when you flash an update for that rom: wipe Cache and Dalvik Cache, Install update.
Stepts of installing a new rom:
1) Put the rom and gapps on your device
2)Wipe Data, Cache, Dalvik Cache and System
3)Flash the system and then the gapps
4)Reboot
Stepts of installing an update for the rom:
1)Put the updated file on your device
2)Wipe Cache and Dalvik Cache
3)Install updates
4)Reboot
