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.

installing RC1 using rom manager over original ROM

When installing CM 10.1 RC1 using rom manager over original ROM.
Do I need to clear some partitions manually or does rom manager do all for me?

For eliminating causes for some problems that may be appear is recommended to do:
- wipe data/factory reset
- wipe cache partition
- wipe dalvick cache
- format system
Doing that, you have a clear fresh device for installing new software.

shouldn't this be done by rom manager automatically?

Instruction

How do i update from cm 10.2.1 stable to cm 11 on Samsung I9000 Instruction is really needed!!!!

1. Download cm11
2. Do a full wipe (wipe data, cache, dalvik cache and format /system)
3. Flash cm 11
4. Flash gapps
5. Reboot
Sent from my GT-I9000 using XDA Free mobile app

Update recovery before updating to CM11.
Download CM11
Download GApps
I think you don't need to wipe cache dalvik data If you are updating from CM's previous version.
Install the ROM
Install GApps
Reboot system
Enjoy the ROM...

gapps

I used the wrong gapps and now they're system apps. Can I uninstall them and flash new gapps (already have new gapps). I also can boot into TWRP and trying to use the S SlimRom

Just wipe and reinstall SlimLP + the gapps you want.

What kind of wipe?

You can try wiping cache, dalvik cache and system. Aka dirty flash.
If there is any problem then wipe dalvik cache, cache, data and system.
